× We assessed the potential effectiveness of human milk banking and lactation support on provision of human milk to neonates admitted in the newborn unit (NBU) at Pumwani Maternity Hospital, Kenya. This pre–post intervention study collected data from mothers/caregivers and their vulnerable neonates or term babies who lacked sufficient mother's milk for several reasons admitted in the NBU. The intervention included establishing a human milk bank and strengthening lactation support. Preintervention data were collected between 5 October 2018 and 11 November 2018, whereas postintervention data were collected between 4 September 2019 and 6 October 2019. Propensity score-matched analysis was performed to assess the effect of the intervention on exclusive use of human milk, use of human milk as the first feed, feeding intolerance and duration of NBU stay. The surveys included 123 and 116 newborns at preintervention and postintervention, respectively, with 160 newborns (80 in each group) being included in propensity score matched analysis. The proportion of neonates who exclusively used human milk during NBU stay increased from 41.3% preintervention to 63.8% postintervention (adjusted odds ratio [OR]: 2.68; 95% confidence interval [CI]: 1.31, 5.53) and those whose first feed was human milk increased from 55.0% preintervention to 83.3% postintervention (adjusted OR: 5.09; 95% CI: 2.18, 11.88). The mean duration of NBU stay was 27% (95% CI: 5.8%, 44.0%) lower in the postintervention group than in the preintervention group. The intervention did not affect feeding intolerance. Integrating human milk banking and lactation support may improve exclusive use of human milk among vulnerable neonates in a resource limited setting.

× Dairy foods are an important source of essential macro- and micronutrients in household diets, and their consumption is associated with reduced malnutrition, especially among young children. Low dairy consumption in many developing countries is a justification for programs that promote dairy livestock ownership, help develop dairy value chains, or stimulate dairy demand. While several studies confirm the beneficial effects of such dairy-specific interventions on nutritional outcomes, the purpose in this study is to consider more broadly the contribution of dairy to overall diet quality. Our assessment of consumer preferences for dairy, coupled with simulations of consumption responses to dairy price and household income changes, provide quantitative evidence that can inform policymakers about the possible effects of public policies on dairy consumption and diet quality. While our analysis is based on data from Kenya and Uganda, both countries with established dairy sectors, our findings are relevant for other East African countries with similar dietary patterns and emergent dairy sectors.

× Seed systems are essential to bring good genetic material to farmers. Women farmers, however, have benefited less than men farmers from seed systems in low and middle income countries. We identify factors that inhibit and promote women's success in seed businesses through three case studies of women's and men's entrepreneurship across seed-related value chains and country contexts: tilapia seed production in Ghana, marketing and trading of improved maize and sorghum seeds in Kenya, and chicken seed dissemination in Tanzania. Applying a gender lens, we use key informant interviews and focus group discussions to analyze women's and men's motivations to engage in seed businesses, the challenges they confront to start and build their enterprises, and prospects for sustainability and continued success. We use quantitative data to characterize the levels of empowerment of the agripreneurs sampled. For women, the results show that the social normative context of the sector is critical. Time flexibility and profitability are important considerations for women's engagement. Furthermore, across all three country cases, family and external support are frequently key to women's participation and success in seed agripreneurship. The article discusses the importance of government bodies, NGOs, and donors in challenging the normative context around gender resource gaps, as well as provide technical packages and training to develop business acumen. Supporting change of restrictive gender norms in non-threatening ways - such as ICTs - is key.

× Child undernutrition is a persistent challenge in arid and semi-arid areas due to low and erratic rainfall, recurrent droughts and food insecurity. In these settings, caregivers face several challenges in accessing health services for sick and/or malnourished children, including long distances to health facilities, harsh terrain, and lack of money to pay for transportation costs to the health facilities, leading to low service coverage and sub-optimal treatment outcomes. To address these challenges and optimize treatment outcomes, the World Health Organization recommends utilizing community health volunteers (CHVs) to manage acute malnutrition in the community. This study explored the perceptions of community members regarding acute malnutrition treatment by CHVs in Turkana and Isiolo counties in Kenya. The study utilized a cross-sectional study design and included a purposive sample of caregivers of children, CHVs, officers who trained and supervised CHVs and community leaders in the intervention area. Focus group discussions and key informant interviews were used to explore perceptions towards the management of acute malnutrition by CHVs. Generally, caregivers and CHVs perceived the intervention to be beneficial as it readily addressed acute malnutrition treatment needs in the community. The intervention was perceived to be acceptable, effective, and easily accessible. The community health structure provided a platform for commodity supply and management and CHV support supervision. This was a major enabler in implementing the intervention. The intervention faced operational and systemic challenges that should be considered before scale-up.

× We investigate the effect of a modest food safety premium on semisubsistence farmers' investment in a food safety technology. We demonstrate theoretically that in the face of production uncertainty, a market incentive below the marginal production cost of achieving the safety standard can increase food safety investment among farmers motivated by private health returns. We test this prediction through a randomized controlled trial in Kenya through which members of existing farmer groups were offered an opportunity to purchase a food safety input, and half were offered a 5% market premium for produce that met the associated regulatory standard. Access to the premium more than doubled investment in the food safety technology. In line with the model's prediction, most premium-induced adoption was by farmers motivated by a combination of health and financial rewards.

× Prosopis juliflora is an invasive alien leguminous tree introduced as a way of combating desertification, deforestation, and improving soil fertility. Over time, the tree has reported significant negative externalities to farmers. Different strategies such as management through utilization and complete eradication have been proposed to reduce these externalities. We investigate the various factors associated with adherence to these strategies. In the first place, we assess the correlates of charcoal production, beekeeping, and willingness to completely eradicate Prosopis. We then examine the welfare effects of charcoal production and beekeeping. We use survey data from 530 smallholder households in the Baringo county of Kenya who are currently contending with infestation from the invasive tree. Besides other factors, we show that a positive perception about Prosopis invasion increases the probability of engaging in charcoal production and is adversely related to beekeeping and the willingness to completely eradicate Prosopis. Delving into welfare and poverty effects of these activities, we find charcoal production to be income increasing. We argue that a blend of both management and eradication of Prosopis could offer a win-win solution to both improving the welfare and socio-economic conditions of households while also ensuring environmental and ecological safeguards, with implications for broad-based sustainability.

× Anaemia is a global public health problem affecting 800 million women and children globally. Anaemia is associated with perinatal mortality, child morbidity and mortality, mental development, immune competence, susceptibility to lead poisoning and performance at work. The objective of this article is to identify whether antenatal care-seeking was associated with the uptake of iron supplementation among pregnant women, adjusting for a range of covariates. This article used data from the cross-sectional recent Demographic and Health Surveys (DHS) of 12 countries in Asia, Africa and Latin America & the Caribbean regions. The individual-level data from 273,144 women of reproductive age (15−49 years) were analysed from multi-country DHS. Multiple Logistic regression analyses were conducted using Predictive Analytics Software for Windows (PASW), Release 18.0. Receiving at least four antenatal care visits was significantly associated with the consumption of 90 or more iron-containing supplements in 12 low and middle income countries across three regions after adjusting for different household and respondent characteristics, while mass media exposure was found to be a significant predictor in India and Indonesia. Antenatal care seems to be the most important predictor of adherence to iron intake in the selected countries across Africa, Asia, Latin America and Caribbean regions.

× Food insecurity remains a serious challenge for many households in Africa and the situation is even more prevalent among young people. However, there is a dearth of empirical evidence on youth food security status in Africa. We assessed the level and determinants of food security among young farmers in Africa. We adopted a multi-stage sampling technique to select 400, 429, and 606 young farmers in Kenya, Nigeria, and Uganda, respectively. Individual food consumption was assessed following a 7 days recall method. The Food Consumption Score, which combines dietary diversity and consumption frequency was used to assess food security status while the determinants of food security were identified using a logistic regression model. Results suggest low dietary diversity across the three countries. Also, the majority of the respondents had an unacceptable food consumption score, suggesting that despite being food producers, young farmers are still food insecure. The odds of being food secure was positively determined by access to extension services, participation in the ENABLE TAAT business incubation programme, and access to market information but, negatively by access to credit, number of employees, Covid-19 pandemic, and location. Additionally, the food security status of young female farmers was positively influenced by age, suggesting that younger youths are less food secure compared to older ones. These results suggest that more efforts should be directed towards improving the food security of young African farmers and that policy- and programme-level interventions should support access to extension services, market information, and land. Additionally, more investments should be directed towards developing need-based agribusiness incubation programmes with an effort to scale existing programmes beyond the regular one-time period.

× This article analyzes two longitudinal datasets (October – December 2020; April 2021) of 1,000 and 900 women in Kenya and Nigeria, respectively, alongside in-depth qualitative interviews with women at risk of changes to time use, to study two pandemic issues: women’s substitution of paid for unpaid work and how these shifts compromise their mental health. Women devote more time to domestic care (30–38 percent), less time to employment (29–46 percent), and become unemployed (12–17 percent). A rise in domestic work is correlated with depressive (Nigeria) and anxiety symptoms (Kenya and Nigeria). Women with greater agency (Kenya) and fewer children (Nigeria) are less likely to report a domestic burden or loss in paid activities. Social protection programs may fill the void of assistance traditionally provided by informal networks in the short term, while campaigns shifting norms around household work may preserve women’s economic participation in the long term.

× Background: The coronavirus disease 2019 (COVID-19) pandemic has had large negative effects on countries’ economies and individual well-being throughout the world, particularly in low- and middle-income countries. Pandemic-related changes in behavior and government restrictions in Kenya may have negatively affected food supply chains and household food access; however, the empirical evidence is currently limited.
Objectives: The study explored changes in informal milk markets, dairy consumption, and food insecurity among low-income households in urban and periurban Nairobi, Kenya, following the start of the COVID-19 pandemic in the country.
Methods: Baseline data on milk sales and consumption were collected in late 2019 from dairy vendors operating in the informal sector and their dairy customers. We conducted 2 longitudinal telephone surveys with the same study participants in July and September–October 2020, respectively.
Results: At the first follow-up, the volume of milk sold by informal vendors had dropped by 30% compared with their baseline level, and the volume of milk from informal markets consumed by households decreased by 23%. By the second follow-up, the volume of milk sold and consumed had recovered somewhat but remained lower than the volume observed 1 y prior in the same season. Large reductions in the consumption of other animal–sourced products were also observed. The rate of food insecurity increased by 16 and 11 percentage points in the first and second follow-up periods, respectively, compared with baseline.
Conclusions: The evidence, therefore, suggests that the timing of the pandemic and the related restrictions were associated with a decrease in the supply and consumption of milk from informal markets in Nairobi and a decrease in the food security of periurban consumers.

× Background
Malaria remains a public health problem in Kenya despite several concerted control efforts. Empirical evidence regarding malaria effects in Kenya suggests that the disease imposes substantial economic costs, jeopardizing the achievement of sustainable development goals. The Kenya Malaria Strategy (2019–2023), which is currently being implemented, is one of several sequential malaria control and elimination strategies. The strategy targets reducing malaria incidences and deaths by 75% of the 2016 levels by 2023 through spending around Kenyan Shillings 61.9 billion over 5 years. This paper assesses the economy-wide implications of implementing this strategy.

Methods
An economy-wide simulation model is calibrated to a comprehensive 2019 database for Kenya, considering different epidemiological zones. Two scenarios are simulated with the model. The first scenario (GOVT) simulates the annual costs of implementing the Kenya Malaria Strategy by increasing government expenditure on malaria control and elimination programmes. The second scenario (LABOR) reduces malaria incidences by 75% in all epidemiological malaria zones without accounting for the changes in government expenditure, which translates into rising the household labour endowment (benefits of the strategy).

Results
Implementing the Kenya Malaria Strategy (2019–2023) enhances gross domestic product at the end of the strategy implementation period due to more available labour. In the short term, government health expenditure (direct malaria costs) increases significantly, which is critical in controlling and eliminating malaria. Expanding the health sector raises the demand for production factors, such as labour and capital. The prices for these factors rise, boosting producer and consumer prices of non-health-related products. Consequently, household welfare decreases during the strategy implementation period. In the long run, household labour endowment increases due to reduced malaria incidences and deaths (indirect malaria costs). However, the size of the effects varies across malaria epidemiological and agroecological zones depending on malaria prevalence and factor ownership.

Conclusions
This paper provides policymakers with an ex-ante assessment of the implications of malaria control and elimination on household welfare across various malaria epidemiological zones. These insights assist in developing and implementing related policy measures that reduce the undesirable effects in the short run. Besides, the paper supports an economically beneficial long-term malaria control and elimination effect.

× Small and medium enterprises (SMEs) in Kenya were severely affected by the COVID-19 pandemic and restrictions put in place to contain it. This study assesses the impact of these restrictions on the midstream of the potato and fish value chains, with a focus on traders and processors, and investigates the short- and longer-term responses and ‘pivoting’ strategies deployed by these firms. Longitudinal data were collected from 937 respondents with three recall periods: (1) the pre-pandemic situation (2019); (2) the period of strictest restrictions, necessitating immediate adaptations by firms (2020); and (3) a period of anticipated recovery with longer-term business adaptation strategies (2021). Firms in both value chains reported a dramatic drop in turnover in 2020. Potato SMEs partially recovered in 2021, but fish SMEs reported further declines in turnover. In the face of restrictions, SMEs shifted toward more localized procurement and sales, shorter supply chains (often by-passing intermediaries and increasing use of contracts), use of smaller vehicles, and toward the adoption of information and communication technology (ICT) to search for and engage with business partners. Smaller firms and the biggest of businesses were more resilient and less subject to large fluctuations in business turnover, suggesting an inverted U-shape relationship between firm size and impact. Firms located close to production areas and selling primarily within their own county were also less affected. We provide recommendations for increasing business resilience to shocks based on these findings.

× Aspirations influence future-oriented behavior and ensuing outcomes but they may also fail to do so when the aspired-to-status is far away from the current one. Theoretical predictions suggest an inverted U-shaped relationship between this aspiration gap and the effort to achieve what is aspired to. Aspirations that are ahead but not too far ahead of the current status serve as the best incentives for investments. We examine the income aspiration gap of smallholder households and relate it to livestock in a pastoral setting in Northern Kenya. Our focus on livestock is guided by the burgeoning recognition of livestock as an investment and saving conduit for many households in pastoral communities in developing nations. Employing different empirical strategies including parametric and semi-parametric techniques, we find livestock to be increasing with aspirations up to a threshold, from which it then declines to lead to an aspiration failure. Delving into livestock heterogeneity, we uncover evidence that cattle and poultry respond more to the aspiration gap than small ruminants such as sheep and goats. Different U-shaped tests confirm this relationship, bolstering the evidence of an aspiration failure. These findings are robust to the inclusion of relevant controls, truncations at zero, and different variable transformations. We also show that the findings are unlikely to be driven by unobserved heterogeneity. Additionally, we find that internal locus of control, that is the degree to which individuals believe they control outcomes in their lives is associated with livestock investments.

× Scant evidence exists to identify the effects of the pandemic on migrant women and the unique barriers on employment they endure. We merge longitudinal data from mobile phone surveys with subnational data on COVID cases to examine whether women were left more immobile and vulnerable to health risks, relative to men, during the pandemic in Kenya and Nigeria. Each survey interviewed approximately 2000 men and women over three rounds (November 2020–January 2021, March–April 2021, November 2021–January 2022). Linear regression analysis reveals internal migrants are no more vulnerable to knowing someone in their network with COVID. Rather, rural migrant women in Kenya and Nigeria were less vulnerable to transmission through their network, perhaps related to the possible wealth accumulation from migration or acquired knowledge of averting health risks from previous destinations. Per capita exposure to COVID cases hinders the inter-regional migration of women in both countries. Exposure to an additional COVID case per 10,000 people resulted in a decline in women’s interregional migration by 6 and 2 percentage points in Kenya and Nigeria, respectively.

× Several countries across the developing world have designed and implemented agricultural export incentives. However, little is known about the effects of these policies on various aspects of domestic food security. This study utilizes economywide models linked top-down with microsimulation modules to analyze the impacts of increased agricultural export promotion on the four dimensions of food security – availability, access, utilization, and stability – in three structurally food-insecure economies of Ethiopia, Kenya, and Uganda. We find that agro-export promotion adversely affects all four aspects of food security in urban areas and at the national level due to significant increases in food prices domestically. However, it generally benefits households in rural areas. The food security effects are stronger in Ethiopia and Kenya. We also find that risks associated with the volatility in international markets and declines in domestic productivity can lead to further deterioration in access to food when countries implement outward-oriented agricultural policies

× Limited access to reliable financial instruments makes it difficult for rural households to manage daily cash flows. Selling goods through cooperatives can improve savings, but cooperative income is not easily accessible when facing an emergency. Cash-constrained households may therefore side-sell in local markets that pay on the spot, while insurance could reduce the need to side-sell. We test these hypotheses using panel data for farmers from two Kenyan dairy cooperatives. Both cooperatives pay only once a month, with local market vendors paying a lower price but upon delivery. We find that farmers sell less milk to the cooperatives when facing uninsured health emergencies or when cash on hand is low. Health insurance reduces side-selling. These findings highlight that selling, saving and risk-coping decisions are intertwined, with side-selling providing a strategy to manage temporary cash constraints. This suggests that linking agricultural and insurance contracts can enhance cooperatives’ financial sustainability.

× The COVID-19 pandemic prompted social distancing, workplace closures, and restrictions on mobility and trade that had cascading effects on economic activity, food prices, and employment in low- and middle-income countries. Using longitudinal data from Bangladesh, Kenya, and Nigeria covering a period from October 2020 to April 2021, the paper assesses whether knowledge of a person infected with COVID-19 is associated with food insecurity, job loss and business closures, and coping strategies to smooth consumption. The likelihood of households to experience food insecurity at the extensive and intensive margins increased among those who knew an infected person in Bangladesh and Kenya.

× As an unobservable attribute, food safety is likely to be under-provided by markets where regulatory enforcement is weak. In such settings, stimulating consumer demand for safer food can potentially encourage market actors to invest in food safety. Through a randomized trial in Kenya, we test the impact of informing consumers about which maize flour brands are most likely to comply with the regulatory standard for aflatoxin, a carcinogenic fungal byproduct. Providing information on safer brands alone does not significantly affect consumption behavior. However, when the same information is combined with a test performed on the maize flour stocked by the household, the likelihood that a safer brand is consumed 2 months later is 76% higher than in the comparison group. Our findings suggest that providing information on the relative riskiness of substitute foods could encourage consumers to make safer choices.

× Parthenium hysterophorus L. (Asteraceae) is an invasive alien weed with detrimental effects on agricultural production, biodiversity, human and animal health, threating rural livelihoods in Asia and Africa. The problem emerged recently in the Kenyan Rift Valley, where it began to affect the landholdings of both agro-pastoralists and crop farmers. These vulnerable smallholders depend heavily on natural resources for their livelihoods. In this study, we assessed the severity of parthenium invasion and farmers’ management responses using a sample of 530 agro-pastoralists in Baringo County, Kenya, in 2019. We hypothesise that the implementation of existing management strategies depends on the state of parthenium invasion and household socio-economic characteristics. The prevalence and severity of parthenium invasion differed greatly among field plots. To control weeds, farmers resort to either hand weeding, the use of synthetic herbicides, or intensive tillage, sometimes in combination with mulching. A multivariate probit regression model shows that households’ characteristics determine the type of control strategies used as well as their complementarity and substitutability. Hand weeding is the most common option, adopted by almost 40% of farmers. The use of agrochemicals or soil-based control strategies appears to be related to knowledge and information characteristics such as access to extension services, membership in organisations and the educational level of household heads. While hand weeding and the use of synthetic herbicides depict significant substitutability, the latter strategy is limited to a few larger farms with market-oriented production. As parthenium invasion continues, policies need to improve farmer awareness and access to knowledge to enable pro-poor and environmentally sustainable control of parthenium on smallholder farms.

× Non-cognitive skills such as locus of control (LOC) and self-efficacy have been theoretically shown to influence behavioural and economic decision-making. While this effect has been confirmed empirically, the factors that can induce change in non-cognitive skills are not yet fully understood. Examining exogenous variation in the spread of invasive species, this study investigates the association between an ecological shock and non-cognitive skills through a survey of smallholder households in Baringo county Kenya. The results show an adverse relationship between ecological shocks and LOC. Individuals are less likely to believe that they have control over outcomes in their lives when faced with shocks. The study also demonstrates a negative association of shocks with self-efficacy which is related to the perceived judgement of capability. In addition to robustness to alternative specifications and the inclusion of additional relevant controls, we establish that the results are unlikely to be driven by unobserved heterogeneity. We find further suggestive evidence indicating that ecological shocks lead to economic adversity, which may well explain reductions in individuals' perceptions of capability and the extent of convictions regarding control over their lives. Overall, ecological shocks diminish perceived LOC and self-efficacy, with associated policy implications for poverty reduction.

× Consumption of microbiologically contaminated food is one of the leading causes of diarrheal diseases. Understanding the source of enteric pathogens in food is important to guide effective interventions. Enterobacteriaceae bacterial assays typically used to assess food safety do not shed light on the source. Source-specific Bacteroides microbial source tracking (MST) markers have been proposed as alternative indicators for water fecal contamination assessment but have not been evaluated as an alternative fecal indicator in animal-derived foods. This study tested various milk products collected from vendors in urban Kenyan communities and infant foods made with the milk (n = 394 pairs) using conventional culture methods and TaqMan qPCR for enteric pathogens and human and bovine-sourced MST markers. Detection profiles of various enteric pathogens and Bacteroides MST markers in milk products differed from that of milk-containing infant foods. MST markers were more frequently detected in infant food prepared by caregivers, indicating recent contamination events were more likely to occur during food preparation at home. However, Bacteroides MST markers had lower sensitivity in detecting enteric pathogens in food than traditional Enterobacteriaceae indicators. Bacteroides MST markers tested in this study were not associated with the detection of culturable Salmonella enterica and Shigella sonnei in milk products or milk-containing infant food. The findings show that while Bacteroides MST markers could provide valuable information about how foods become contaminated, they may not be suitable for predicting the origin of the enteric pathogen contamination sources.

× Aquaculture must grow above the current rate of 11% per year to meet projected demand and reduce dependence on seafood imports. Government support and private investment are urgently needed for sustainable growth.

× Background: Milk is a common infant food in peri-urban Kenya that can transmit diarrhea-causing enteric pathogens. Little is known about how contamination of milk at point of purchase and household handling of milk-based infant foods contribute to infant exposure to enteric pathogens.
Objective: To compare the prevalence and concentrations of bacterial indicator organisms and enteric pathogens in unpackaged, fresh pasteurized, and ultra-high temperature (UHT) treated milk at purchase and assess the influence of the type of milk used to prepare infant food on contamination of this food.
Methods: Paired samples of purchased milk and infant food prepared with this milk were obtained from 188 households in low-income neighborhoods in Kisumu, Kenya. Samples were cultured on selective media to isolate Salmonella enterica, Shigella spp., Klebsiella aerogenes, Proteus spp., and Escherichia coli, with pathogens validated by PCR. Probability of detection of these bacteria was compared by milk product treatment and packaging method, and between milk at point of purchase vs. food at point of infant consumption.
Results: Unpackaged milk was most contaminated at point of purchase, but bacterial contamination was also present in pasteurized and UHT milk at purchase. Presence of bacteria in UHT and fresh pasteurized milk at purchase predicted presence of the same bacteria type in infant food. Prevalence of bacterial contamination and concentration level for bacterial indicators generally increased between point of purchase and consumption in UHT and fresh pasteurized milk-based food but decreased in unpackaged milk-based food. Prevalence of the four fecal bacteria were similar in infant foods prepared with each type of milk.
Conclusion: Both pre-market contamination and post-purchase handling influence the likelihood of infants ingesting foods contaminated by diarrheal pathogens.

× This study assesses the extent of COVID-19-related food insecurity in Kenya, Tanzania, and Namibia. Using the Household Food Insecurity Access Scale, we measure food insecurity in various dimensions and document several food access disruptions associated with the COVID-19 pandemic between April and July 2020. Furthermore, we assess the association of COVID-19 countermeasures with the adoption of various strategies in line with the coping strategies index. We rely on a unique phone survey that followed households who participated in an earlier field-based survey. First, through Ordinary Least-Squares and Probit regressions, we show a strong and statistically significant association between COVID-19 countermeasures and food access disruptions and food insecurity in each of the three countries. We then use a multivariate probit regression model to understand the use of the various coping strategies, including reducing food intake, increasing food search, and relying more on less nutritious foods. We provide evidence on the complementarities and trade-offs in using these coping strategies. COVID-19 and related lockdown measures coincided with a deleterious increase in food insecurity in rural Africa.

× Multistakeholder platforms (MSPs) are the subject of increasing attention and investment in the domain of collaborative natural resource governance, yet evidence-based guidance is slim on policy and investment priorities to leverage the MSP approach. We provide a comparative analysis of eight landscape-level MSPs spanning seven countries (Peru, Brazil, India, Tanzania, Ethiopia, and a cross-border case from Kenya and Somalia), representing a diversity of resource systems covering forests, rangelands, and multiuse agricultural landscapes. Applying an adapted social-ecological systems framework, our synthesis identifies the influence of these MSPs on patterns of stakeholder interaction and draws implications for the design and organization of MSPs that are both appropriate and effective. From the cases, we distill lessons addressing: (1) how to design an MSP in relation to the governance context, including the fit between institutional and ecological dimensions of the system and with attention to cross-scale linkages; (2) how to implement inclusive processes that address power inequities, including through capacity building and procedural rules; and (3) how to support adaptive learning to expand the MSP’s influence over time, including monitoring outcomes, adapting the scope of stakeholder engagement, and investing in MSP durability.

× There is resurging interest in community-based natural resource management (CBNRM) as an approach for achieving global biodiversity conservation goals. Yet, CBNRM remains dominated by men, elevating the importance of designing programs that give voice and agency to women. Arguments for increasing gender balance within CBNRM often assume women have strong preferences for equality and altruism and would therefore be better environmental stewards. Evidence on the effect of gender balance on commons management, however, remains mixed. We report on two framed field experimental games with community members directly engaged in the use and management of natural resources in rural Kenya. Participants were randomly assigned to single-gender (all male n = 23; all female n = 28) or mixed gender groups (n = 36) to assess the role of gender composition on group and individual decisions. The two games provide unique insights into the give (public good games) and take (extraction games) decisions common in natural resource management. We find mixed gender groups tend to achieve more socially optimal outcomes than single-gender groups in the public goods game context, but all male groups tended to conserve the most in the extraction game. Women are not necessarily more likely to make prosocial decisions than men, and factors such as framing and social relations affect decisions. Our results indicate gender composition affects group decision-making and is therefore important for commons management, and that mixed gender groups can be more effective than single-gender groups. Improving gender balance in CBNRM may help achieve more desirable outcomes from a social and conservation perspective but understanding decision-making contexts is critical.

× Informal milk trading in peri-urban Nairobi plays a key role in supporting both livelihoods and nutrition, particularly among poor households. Gender dynamics affect who is involved in and benefits from milk trading. To better understand gendered constraints and opportunities in informal, peri-urban dairy marketing, a qualitative study was conducted in 2017 with 45 men and 50 women milk traders in Dagoretti, a peri-urban area of Nairobi, Kenya. The findings show that milk trading is more lucrative for older men than for women and younger men among the respondents. This article illustrates the differences between these women’s and men’s experiences as milk traders and explores the reasons behind these differences. It discusses the implications of the findings for agricultural research and development interventions that aim to enhance the sustainability and equity of the dairy sector.

× In 2022, the world is experiencing the greatest cost of living crisis in a generation.1 Crises have always highlighted inequities in our societies. With food prices at near record levels globally, rapidly rising inflation, and economic instability, many people living in situations of constraint have no choice but to skip meals, reduce the amount they eat, prepare meals with fewer nutritious foods, and buy cheaper, starchy staples and ultra-processed foods.2, 3 The implications for health inequalities are dire: increased dietary disparities will worsen food insecurity, undernutrition, obesity, and diet-related disease among those who are struggling most.

× Mechanization, digitalization, and rural youth engagement are central to African agricultural transformation. Each of these topics is associated with debates on opportunities, risks, and appropriate policy actions, which become visible in international research discourses and policy fora. In contrast, little is known about the viewpoints of national stakeholders. This paper explores the viewpoints of 195 respondents from different stakeholders categories in Benin, Kenya, Nigeria, and Mali. The results reveal hitherto neglected aspects, e.g., the role of animal traction, the continued appeal of state-led mechanization, and data sovereignty concerns. Gender, age, and education influence the viewpoints on some topics. Paying attention to local stakeholders can help to choose and design the most promising policies/programs and ensure their implementation on the ground.

× In countries where regulatory enforcement is weak, voluntary third‐party verification of firms' food safety processes can allow concerned consumers to select safer products. However, due in part to their legal ambiguity, and the potential to attract additional regulatory scrutiny, food safety claims are rarely made by firms. As a result, the impact of such claims on consumer demand is not well understood. We examine how labeling maize as tested for aflatoxin, a carcinogen also associated with stunting in children, affects sales. By randomly varying the timing and intensity of a marketing campaign to promote the first maize flour brand in Kenya labeled as tested for aflatoxin, we characterize dynamic consumer response to information about food safety. We find an immediate response in sales to marketing alone, which disappears as soon as marketing ceases. Sales remain elevated in the weeks after a temporary discount is offered, but this effect also fades over time and is not associated with greater awareness of the firm's food safety claims. These results suggest that it is unrealistic to expect for‐profit firms serving mass markets in low‐ and middle‐income countries to invest heavily in marketing based on food safety claims.

× Over the last two decades, prevalent technologies and Internet of Things (IoT) systems have been found to have potential for carrying out environmental monitoring. The data generated from these infrastructures are readily available and have the potential to provide massive spatial coverage. The costs involved in using these data are minimal since the records are already generated for the original uses of these systems. Commercial microwave links, which provide the underlying framework for data transfer between cellular network base stations, are one example of such a system and have been found useful for monitoring rainfall. Wireless infrastructure of this kind is deployed widely by communication providers across Africa and can thus be used as a rainfall monitoring device to complement the sparse proprietary resources that currently exist or to substitute for them where alternatives do not exist. Here we focus this approach’s potential to acquire valuable information required for agricultural needs across Africa using Kenya as an example.

× Evidence is emerging that foodborne illness accounts for a staggering health burden in developing countries. However, standard approaches used by developed country governments to ensure food safety are not appropriate in settings where regulatory enforcement capacity is weak and most firms are small and informal. Using a randomized field experiment, we test the impacts of subsidies and a price premium for safer produce on farmer adoption of technologies that improve food safety. We find that the food safety practices of farmers who produce maize for sale are inferior to those of farmers who produce maize only for household consumption, but that both a price incentive and technology subsidies can partially close this gap. We combine our experimental adoption results with prior evidence on the efficacy of the technologies studied to simulate the public health impacts of alternative policies. Our simulations show that interventions to reduce aflatoxin exposure are likely to be cost-effective based on averted poisoning deaths and cancer cases alone. Potential impacts on stunting, which are not as well established and more difficult to value, would imply additional health benefits. Of the policy options considered, providing training and plastic drying sheets to farmers free of charge is the most cost-effective.

× The optimal design of informal contracts in agricultural value chains depends on when farmers prefer to be paid for their output. While the evidence from time preference experiments suggests a preference for early payments, field studies often indicate that farmers will defer regular payments if given the opportunity. In this study, we explicitly test whether farmers are more patient regarding regular, earned income than regarding experimental windfall payments. We asked farmers in a dairy cooperative in Kenya to allocate both their milk income and a one-time gift between an early and a deferred payment date. We find that a large majority of participants deferred their milk payments, while rarely choosing to defer the gift. Participants’ survey responses suggest that we observe this difference because of mental accounting: participants earmarked their regular milk payments, but not the gift, to save for bulky expenditures. We conclude that deferred payments can provide value to producers by functioning as a savings device, even when decisions over windfall income suggest a preference for early payments.

× Texas A&M AgriLife Research (hereafter AgriLife) introduced a quality systems approach to accurately measure and manage aflatoxin that resulted in improved food safety for approximately 10 million Kenyans. A quality systems approach contains elements that ensure laboratory testing competence. In this study, quality system elements included analyst training and qualification, proficiency testing, use of reference material to support analytical traceability and define analytical uncertainty, development and implementation of a food safety plan by commercial maize (Zea mays) millers, and verification of testing accuracy at the AgriLife laboratory accredited by the Kenya Accreditation Service under the International Organization for Standardization/International Electrotechnical Commission 17025:2005 standard. In 2014 and 2015, five proficiency rounds were performed, ranging in aflatoxin concentrations of 5 to 40 μg/kg. Five laboratories had a z-score of >3, and all of these were for the fifth proficiency round with an aflatoxin content of 5 μg/kg. In 2015, 31 analysts qualified to participate in the program at 15 maize mills. The analysts' qualification for seven test samples, which ranged from 3.1 to 28 μg/kg total aflatoxin, resulted in an average relative standard deviation of 19.2% across all participants and test methods. Independent testing of participating mill verification results before and after analyst implementation of the quality systems approach revealed an improvement in measure accuracy.

× Violence against children is a pervasive public health issue, with limited data available across multiple contexts. This study explores the rarely studied prevalence and dynamics around disclosure, reporting and help-seeking behaviours of children who ever experienced physical and/or sexual violence.

× Food systems in developing countries are changing rapidly with a growing role of modern supermarkets. Supermarkets influence supply chains and the way agricultural products are sourced from farmers. Especially for the procurement of fresh fruits and vegetables, supermarkets often contract farmers directly to ensure consistent and high-quality supply. One important question, which is addressed here, is whether smallholder farmers benefit from supermarket contracts. Previous studies address this question, but mostly focus on income effects without exploring implications for other dimensions of household welfare, such as nutrition, health, or housing conditions. Moreover, most existing studies rely on cross-section data. We add to the literature by analyzing effects of supermarket contracts on income and multidimensional poverty using three rounds of panel data collected from smallholder vegetable farmers in Kenya and econometric models with household fixed effects. On average, supermarket contracts increase household income by over 40%. We also find significant reductions in income poverty and multidimensional poverty. Quantile regressions show that farmers in all income groups benefit, but richer households benefit more than poorer ones in absolute terms. However, supermarket contracts cause the strongest reductions in multidimensional deprivations among the poorest households.

× Implementation of decentralized and pluralistic policies in provision of extension services has led to increased availability of actors providing extension services to farmers in most developing countries including Kenya. What is unique about extension services providers is that they have a shared goal of improving agricultural productivity. However, in some cases these providers differ in their knowledge regarding the practices or knowledge that is required to improve agricultural productivity. Lack of shared knowledge among providers has contributed to delivery of uncoordinated and duplication of efforts thereby limiting the effectiveness of efforts in extension services delivery. Moreover, in some cases lack of shared knowledge has contributed towards provision of conflicting information which has left farmers confused. Enhancing coordination and collaboration among these representatives is of paramount importance if their efforts to improve agricultural productivity are to be successful. Having structures in place that bring together organizations that have shared goals is an important step in facilitating coordination. This is based on findings of a case study that was conducted in Kenya with the Kenyan Forum for Agricultural Advisory Services (KeFAAS). The results of the study provide insights that can be used as a starting point when strengthening coordination in extension services delivery in decentralized and pluralistic environments.

× Poultry are important for many poor households in developing countries, but there are many constraints to poultry production, including disease. One of the most important diseases of chickens is Newcastle disease (ND). Even though there are effective vaccines against this disease available in most countries, uptake by small-scale poultry keepers is often low. In this study, two areas in Kenya and Tanzania were studied, where some villages had received additional support to get vaccination and other villages had not. In Kenya, 320 households from 10 villages were interviewed, of which half of the villages had active promotion of vaccination through village-based advisors. In Tanzania, 457 households were interviewed, of which 241 came from villages that have had active support through either a project or government extension services. Knowledge about vaccines and the attitudes towards vaccinating against ND was evaluated using mixed multivariable logistic models. Results indicate that in Kenya, the most important determinants for understanding the function of a vaccine were having had support in the village and to have knowledge about ND signs, while in Tanzania gender and previous vaccine use were important in addition to having had support. Attitudes towards vaccination were mainly determined by knowledge, where more knowledge about how vaccines work in general or about ND contributed to more positive attitudes. Among Kenyan farmers that had never used the vaccine before, the amount of birds they lost to disease and predators also influenced attitudes. In conclusion, this study supports the notion that knowledge is a very important component of extension support and that simply making vaccines available may not be sufficient for high levels of uptake.

× Empirical evidence on the link between agrobiodiversity and dietary diversity appears to be inconclusive. Thus, there arises a need to determine other factors that could significantly influence dietary diversity in different agro-ecological zones, as factors may vary from region to region. The objective of this study was to document the status of agrobiodiversity and dietary diversity and to assess the determinants of dietary diversity among women of reproductive age in two different agro- ecological zones of Rongai Sub-County in Kenya. A cross-sectional study of 384 women aged 18–49 years was conducted. Agrobiodiversity was measured using the Shannon-Wiener index, species richness (count) and production diversity score. A 24-hour dietary recall was used to determine minimum dietary diversity for women (MDD-W) of reproductive age.

× Smallholder producers in sub-Saharan Africa are often unable integrate into markets and access high-value opportunities by effectively participating in global chains for high-value fresh produce. Using data from a survey of large avocado farmers in Kenya, this study examines the determinants and impacts of smallholder-producer participation in avocado export markets on labor inputs, farm yields, sales prices, and incomes, using a switching regression framework to control for selection effects. We found that farmers who participate in export markets differ significantly from nonparticipating farmers: They are older, have somewhat larger farms, have received more training, and own more avocado trees of the Hass variety, the type favored in export markets. Living near a well-functioning avocado farmers’ group is also positively associated with participation in export markets. Participation in avocado export markets will have positive impacts on incomes, revenues, prices, and labor inputs. However, there is an offsetting effect in terms of higher prices and lower volumes, reflecting the stricter quality requirements of export markets. Applying a decomposition analysis, we found that not only differences in endowment sizes, but also differences in returns from endowments in export versus domestic markets, are key to understanding differences in yields, revenues, sales prices, and labor inputs. This suggests that policymakers should not only focus on resource accumulation for farmers, but also pay attention to the inclusiveness of export market participation for smallholder farmers.

× Aflatoxin contamination in maize represents a significant food safety hazard in Kenya. To manage this risk, millers need to properly sample incoming bags of maize. In this study, three firms allowed researchers access to sample three incoming trucks each to quantify sources of variability using a hierarchical sampling design. A total of 180 samples consisting of two samples per bag, ten bags per truck, three trucks per mill, and three mills were sampled in April of 2014 and analyzed for aflatoxins using the Romer-FluorQuant test method. Samples from three trucks were analyzed twice for aflatoxin to define intra-bag variability, and extracts were analyzed in duplicate to quantify analytical variability. The variance was partitioned as follows: mill (1.9%), truck (4.1%), bag (60.8%), in-bag (26.6%), analytical error (6.3%) and residual error (0.3%). Using these data, a power study was conducted to optimize the number of bags per truck that should be sampled. The power test, depicted using a power curve, indicated that 20 bags provided a statistical probability of 0.83. This study characterizes the sources of variability in sampling, and the inclusion of a power study highlights the tradeoffs in the number of bags sampled and the ability to detect small effects in estimating the level of aflatoxin contamination in maize.

× We assess the impact of a package of post-harvest technologies on aflatoxin contamination of maize through a randomized trial in rural Kenya. Some elements of this package (training and provision of plastic sheets for sun-drying) were provided free of charge to all participants in treatment villages and were widely adopted. Others (a mobile drying service and hermetic storage bags) were provided free to a subset of randomly selected farmers in treatment villages while others had to pay. Overall, the intervention reduced aflatoxin contamination by over 50%. Most of this reduction appears to be due training and the use of drying sheets, the lowest-cost of all the technologies offered.

× This paper documents a positive relationship between maize productivity in western Kenya and women’s empowerment in agriculture, measured using indicators derived from the abbreviated version of the Women’s Empowerment in Agriculture Index. Applying a cross-sectional instrumental-variable regression method to a data set of 707 maize farm households from western Kenya, we find that women’s empowerment in agriculture significantly increases maize productivity. Although all indicators of women’s empowerment significantly increase productivity, there is no significant association between the women’s workload (amount of time spent working) and maize productivity. Furthermore, the results show heterogenous effects with respect to women’s empowerment on maize productivity for farm plots managed jointly by a male and female and plots managed individually by only a male or female. More specifically, the results suggest that female- and male-managed plots experience significant improvements in productivity when the women who tend them are empowered. These findings provide evidence that women’s empowerment contributes not only to reducing the gender gap in agricultural productivity, but also to improving, specifically, productivity from farms managed by women. Thus, rural development interventions in Kenya that aim to increase agricultural productivity—and, by extension, improve food security and reduce poverty—could achieve greater impact by integrating women’s empowerment into existing and future projects.

× This paper summarizes evidence on six perceptions associated with cash transfer programming, using eight rigorous evaluations conducted on large-scale government unconditional cash transfers in sub-Saharan Africa under the Transfer Project. Specifically, it investigates if transfers: 1) induce higher spending on alcohol or tobacco; 2) are fully consumed (rather than invested); 3) create dependency (reduce participation in productive activities); 4) increase fertility; 5) lead to negative community-level economic impacts (including price distortion and inflation); and 6) are fiscally unsustainable. The paper presents evidence refuting each claim, leading to the conclusion that these perceptions—insofar as they are utilized in policy debates—undercut potential improvements in well-being and livelihood strengthening among the poor, which these programs can bring about in sub-Saharan Africa, and globally. It concludes by underscoring outstanding research gaps and policy implications for the continued expansion of unconditional cash transfers in the region and beyond.

× Advanced parametric financial instruments, like weather index insurance (WII) and risk contingency credit (RCC), support disaster-risk management and reduction in the world’s most disaster-prone regions. Simultaneously, satellite data that are capable of cross-checking rainfall estimates, the “standard dataset” to develop such financial safety nets, are gaining importance as complementary sources of information. This study concentrates on the analysis of satellite-derived multi-sensor soil moisture (ESA CCI, Version v04.2), the evapotranspiration-based Evaporative Stress Index (ESI), and CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data) rainfall estimates in nine East African countries. Based on spatial correlation analysis, we found matching spatial/temporal patterns between all three datasets, with the highest correlation coefficient occurring between October and March. In large parts of Kenya, Ethiopia, and Somalia, we observed a lower (partly negative) correlation coefficient between June and August, which was likely caused by issues related to cloud cover and the volume scattering of microwaves in sandy, hot soils. Based on simple linear and logit regression analysis with annual, national maize yield estimates as the dependent variable, we found that, depending on the chosen period (averages per year, growing or harvesting months), there was added value (higher R-squared) if two or all three variables were combined. The ESI and soil moisture have the potential to close sensitive knowledge gaps between atmospheric moisture supply and the response of the land surface in operational parametric insurance projects. For the development and calibration of WII and RCC, this means that better proxies for historical and potential future drought impact can strengthen “drought narratives”, resulting in a better match between calculated payouts/credit repayment levels and the actual needs of smallholder farmers.

× Observational studies have documented an association between aflatoxin (AF) exposure and reduced linear growth in infants and young children. Our objective was to assess the effectiveness of reducing AF exposure on child linear growth and serum AF levels in rural areas in Eastern Kenya. Methods: A cluster randomised controlled design was used (28 intervention and 28 control clusters). The intervention arm received a swapping (contaminated maize was replaced with safe maize) and a stockist intervention (households were encouraged to purchase from a stockist supplied with clean maize). Women in the fifth to final month of pregnancy were invited to enrol in the study. Outcomes were child length-for-age Z-score (LAZ), the prevalence of stunting and child serum AFB1-lysine adduct level 24 (endline, primary outcomes) and 11 to 19 months (midline, secondary outcomes) after trial commencement, respectively. The trial was registered with socialscienceregistry.org. Results Of the 1230 unborn children enrolled in the study, 881 (72%) were included in the LAZ and 798 (65%) in the serum AFB1 analysis. The intervention significantly reduced endline ln serum AFB1-lysine adduct levels (intervention effect—0.273, 95% CI −0.547 to 0.001; one-sided p=0.025), but had no effect on endline LAZ or stunting (mean LAZ at endline was −1.64). At midline, the intervention increased LAZ by 0.16 (95% CI −0.009 to 0.33; one-sided p=0.032) and reduced stunting by seven percentage points (95% CI −0.125 to −0.007; one-sided p=0.015), but had no impact on serum AFB1 levels. Conclusion Improving access to AF-free maize substantially reduced endline serum AF, but had no effect on child linear growth. The midline analysis suggests that AF may affect linear growth at younger ages.

× Like many African countries, Kenya is vulnerable to avian flu given its position along migratory bird routes and proximity to other high risk countries. This raises concern about the effect of an outbreak on rural livelihoods. We use a dynamic computable general equilibrium model of Kenya to simulate outbreaks of different severities, durations and geographic spreads. Results indicate that even a severe outbreak does not greatly reduce economic growth. It does, however, have larger implications for poverty, since poultry is an income source for many poor farmers and a major food item in poor consumers’ baskets. Reducing an outbreak's duration and spatial transmission substantially reduces economic losses, although losses still occur when poultry demand falls, even without a confirmed outbreak. Continued monitoring of poultry production and trade is therefore needed, even if an outbreak has not yet occurred. Efforts to enhance government capacity to respond rapidly to infections and improve farmers’ and consumers’ awareness of avian flu are also needed.

× Positive internal innovation has long been a central element of African agricultural development, even if modern efforts to stimulate technical, institutional, and policy innovations in African agriculture have tended to look outwards. This paper examines the role of positive deviance in Kenyan agriculture over the last 75 years to cast doubt on the alleged authoritative sources of policy advice and mandates from the outside. Positive deviance and appreciative inquiry are suggested as organizing frameworks for identifying and amplifying the generation and uptake of internal African innovations." -- Author's Abstract

× This paper suggests that explanations of property rights transformation need to move beyond models of relative price change and state enforcement to include accounts that accommodate conflict and competition among actors, and the possibility that state actors may not provide the enforcement that is often taken for granted. The transition from collective to individualized holdings in Kenya’s Maasailand is burdened with politics and procedural problems that can undermine the gains anticipated in that move. Moreover, in semi-arid ecological settings, individualization results in unstable land holdings, necessitating re-contracting, and reaggregation by individual parcel owners. " -- Author's summary

× This article addresses the methodological complexities inherent in researching poverty, examining how to differentiate the poor from other social groups, and how to assess the relationships between poverty and technology adoption and impact. The use of specific types of quantitative and qualitative methods, the degree to which their integration was achieved, and the benefits of integration are analyzed. Qualitative and quantitative methods are both necessary for understanding the relationship between poverty and technology adoption, but significant interactions between the scientists at all stages of the research is required for the benefits to be fully achieved." --Author's Abstract

× This article explores the factors that contribute to the emergence and adoption of wildlife partnerships in Kenya. This is a management approach based on the concept of collaborative management (comanagement). In addition, the article analyzes two case studies and examines how successful the implementation of partnership projects has been in terms of stewardship, distributional aspects, and fulfilling conservation interests. The key factors found to favor wildlife partnerships include enabling policies, the presence of organizational capacity within user groups, and the access of local communities to benefits from wildlife through land ownership. Furthermore, it was found that the approach has had mixed success because important challenges emerged from its implementation. The article concludes by highlighting several implications for the future of wildlife partnerships in Kenya." -- Authors' Abstract

× The authors describe the case study as follows: "Kenyan horticultural exports have grown at over 6 percent per year for the past 30 years. Since 1974 the value of Kenya’s horticultural exports has increased fourfold in constant dollar terms, reaching US$167 million in 2000 (see figure). As a result, horticulture has become the third largest source of foreign exchange after tourism and tea. More than 25,000 small farmers participate in the sector, accounting for over half of Kenyan horticultural exports." They then examine the impacts and the driving forces of the Kenyan experience and conclude with the key lessons for future successes.

× The recent wave of subdivision of Maasai group ranches is not an isolated event, but rather part of a broader, historical process of transformation in land relations and policy development in Maasailand. Maasai have over time supported land privatization, first by formalizing collective rights in group ranches and more recently by individualizing collective land holdings. Privatization is perceived to be an effective strategy for safeguarding Maasai land claims against appropriation by non-Maasai, the government and elite Maasai. Construction of the Uganda railway in early twentieth century and the subsequent influx of European settlers who were granted individual title to secure their investments are events that began the institutional path of privatization. The persistence and dominance of individualized arrangements regardless of other more optimal property rights options is a result of the dominance of elite interests (supported by state institutions) even as state imposed institutions replaced Maasai customary systems of land allocation. -- Author's Abstract
