The sustainability of diets in sub-Saharan Africa
Sub-Saharan Africa (SSA) faces unique food security and sustainability challenges. The diets in SSA are insufficient on average, but how they compare across various population segments in terms of nutritional adequacy and environmental footprints is not sufficiently understood. Life cycle assessment (LCA) of diets can be useful, but existing life cycle inventories mostly refer to high-income countries. Hence, data and methodological adjustments a…
Spousal cooperation and dietary quality in Cameroon
Spousal cooperation is considered an important intra-household factor that improves wellbeing, yet its role in shaping diets and nutrition remains underexplored. Here, we combine a lab-in-the field experiment with survey data from Cameroon to analyze how spousal cooperation relates to household, children’s, and women’s dietary quality. Spousal cooperation is measured in terms of husband’s and wife’s budget allocations to a public goods game. Regr…
The effects of internet use on smallholder farmers’ income and dietary quality in Bangladesh
Internet access in rural areas of low- and middle-income countries is expanding at a rapid rate and affects how people produce and consume food and other goods and services. This may have implications for the incomes and diets of smallholder farm households, where poverty and undernutrition are still commonplace. In this study, we use primary data collected from 720 farm households in Bangladesh to analyze how internet use affects agricultural pr…
Seasonality of employment and food security in rural sub-Saharan Africa
Many rural households in sub-Saharan Africa rely on rainfed agriculture, meaning that harvests and incomes from farming are highly seasonal. This leads to recurring periods of food insecurity, commonly referred to as lean seasons. Off-farm employment may help mitigate seasonal food insecurity, but evidence on whether it actually does remains scarce. Using panel data from high-frequency phone surveys in Burkina Faso, Malawi, and Uganda, covering t…

Evolving Farm and Off‐Farm Income Sources and Jobs in Rural Africa
Livelihood sources in rural Africa are diverse and dynamic. Using recent primary survey data from four African countries—Kenya, Namibia, Tanzania and Zambia—we consider regions with different conditions related to climate, agroecology, infrastructure and nature conservation to analyse the role of various income sources for households and individuals. Although most rural households are involved in small‐scale farming, we challenge the conventional…
Agrivoltaics increases public acceptance of solar energy production on agricultural land
Competition for land is a key challenge for decarbonized energy transitions. Open-space solar energy farms are gaining in importance but have large land requirements and displace agricultural production. Agrivoltaics offers a compromise, integrating solar panels into existing farming operations. However, adoption of Agrivoltaics remains limited, as it has lower energy output per hectare and higher installation costs than open-space solar. Here, w…

Urbanizing food environments in Africa
Impacts of supermarkets on child nutrition in China
In many emerging countries, agri-food value chains are transforming rapidly. One emblematic trend is the proliferation of supermarkets and other modern retailers. Supermarkets affect the way supply chains are organized and may also influence the types of foods purchased and eaten by consumers. Research on what this means for people’s diets and nutrition is still relatively scant. Here, we analyze the effects of supermarkets on child diets and nut…
Market food environments and child nutrition
Child malnutrition remains a widespread public health problem in sub-Saharan Africa. Providing access to nutritious foods for all is key, but it is not clear how this can be achieved in various local contexts. Here, we analyze the role of markets and food environments for child diets and nutrition in Malawi along a rural-urban continuum. We develop a new methodology to characterize food environments in terms of the variety of fresh and processed …
Maternal employment in high-value agriculture and child nutrition
Maternal employment in floriculture negatively affects child nutritional status. • Floriculture employment reduces women’s time for childcare and diet quality. • Yet, floriculture employment increases female financial autonomy. • It increases total household income mainly for poorer households. • Policy action needed to improve conditions and avoid undesirable social outcomes. In many low- and middle-income countries, agri-food supply chains are …
Marriage customs and nutritional status of men and women
Analysis of links between marriage customs and nutritional status in Indonesia. • Patrilocality is linked to lower BMI in women, suggesting gender discrimination. • Matrilocality is associated with reduced discrimination against women. • Bridewealth practices are associated with higher BMI among both women and men. • Marriage customs should be explicitly considered in nutrition research and policy. Malnutrition remains a serious problem. While va…
Patterns of temporary rural migration
Migration from rural to urban areas is common in many low- and middle-income countries. However, temporary migration from rural to other rural areas also occurs and is not yet well understood. Here, we conceptualize what drives rural people to migrate temporarily to other rural areas, rather than to urban areas where wages are usually higher. This question is analysed with qualitative data collected through group discussions and in-depth intervie…
Spatial heterogeneity in smallholder oil palm production
What about her? Oil palm cultivation and intra-household gender roles
Oil palm is one of the fastest expanding crops in tropical regions, leading to massive land-use changes and far-reaching social implications. In Indonesia, much of the oil palm land is cultivated by smallholder farmers. While household income effects of oil palm cultivation were analyzed in previous studies, effects on intra-household gender roles are not yet well understood. Here, we use sex-disaggregated survey data from farm households in Suma…
Oil palm cultivation improves living standards and human capital formation in smallholder farm households
Oil palm cultivation is a controversial topic because of its manifold sustainability implications. Recent research in Southeast Asia suggests that oil palm cultivation is associated with income gains for many smallholder farmers, but whether these income gains also translate into longer-term improvements in household living standards remains unclear. Here, we use three rounds of panel data from smallholder farmers in Sumatra, Indonesia, to analyz…
Mobile phones, women's physical mobility, and contraceptive use in India
Women's economic and social empowerment is facilitated by their ability to move around independently and safely. However, in many developing countries women's physical mobility is restricted by social norms, structural impediments related to poor quality of roads and transport systems, and security issues. Restrictions on female physical mobility and low levels of empowerment can also have negative implications for women's access to healthcare se…
Smallholder Farmers’ Dissatisfaction with Contract Schemes in Spite of Economic Benefits
Contract farming is typically seen as a useful mechanism to help smallholders in overcoming market access constraints. However, in spite of economic benefits, high smallholder dropout rates from contract schemes are commonplace. We use quantitative and qualitative data from Ghana to show that smallholder farmers benefit from a resource-providing contract in terms of higher yields and incomes, but that most of them still regret their decision to p…
Using Google data to measure the role of Big Food and fast food in South Africa’s obesity epidemic
Many developing countries face a rapid increase in overweight and obesity, inasmuch as the prevalence has now nearly converged to levels observed in high-income countries. Among other factors, the rise in obesity is caused by a nutrition transition involving higher affordability and consumption of heavily processed or otherwise unhealthy foods containing high amounts of added sugar, fat, and salt. This development is accompanied by the growing ex…
Fairtrade, Agrochemical Input Use, and Effects on Human Health and the Environment
It is often assumed that voluntary sustainability standards – such as Fairtrade – could not only improve the socioeconomic wellbeing of smallholder farmers in developing countries but could also help to reduce negative health and environmental impacts of agricultural production. The empirical evidence is thin, as most previous studies on the impact of sustainability standards only focused on economic indicators, such as prices, yields, and income…
Land-use change, nutrition, and gender roles in Indonesian farm households
Many tropical countries are experiencing massive land-use change with profound environmental and socioeconomic implications. In Indonesia, oil palm cultivation is rapidly expanding at the expense of more traditional crops – such as rubber and rice – and forest land. While environmental effects of the oil palm boom were analyzed in many studies, much less is known about social effects. Here, we analyze how oil palm cultivation by smallholder farme…
Subsistence production, markets, and dietary diversity in the Kenyan small farm sector
Undernutrition and low dietary quality remain widespread problems in poor population segments, especially among smallholder farmers in sub-Saharan Africa. Hence, the question how smallholder systems can be made more nutrition-sensitive is of particular relevance for research and policy. Recent studies analyzed whether increasing farm production diversity may help to improve nutrition. Most existing studies found a positive but small effect on die…
Supermarket contracts and smallholder farmers
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 supe…
Supermarket procurement and farmgate prices in India
Supermarkets have gained in importance in the food systems of many developing countries, with profound implications for smallholder farmers. Several studies analyzed effects of selling to supermarkets on smallholder productivity and income. However, no previous work systematically analyzed effects of supermarkets on farmgate prices, even though prices are important determinants of farmers’ profits and livelihoods. Here, we use data from smallhold…

Can mobile phones improve gender equality and nutrition? Panel data evidence from farm households in Uganda
Since 2000, mobile phone technologies have been widely adopted in many developing countries. Existing research shows that use of mobile phones has improved smallholder farmers’ market access and income. Beyond income, mobile phones can possibly affect other dimensions of social welfare, such as gender equality and nutrition. Such broader social welfare effects have hardly been analyzed up till now. Here, we address this research gap, using panel …
Supply chain differentiation, contract agriculture, and farmers’ marketing preferences
Supermarket Shopping and Nutritional Outcomes
Overweight and obesity are growing health problems in many developing countries. Rising obesity rates are the result of changes in people’s diets and lifestyles. Income growth and urbanization are factors that contribute to these changes. Modernizing food retail environments may also play a certain role. For instance, the rapid spread of supermarkets in many developing countries could affect consumer food choices and thus nutritional outcomes. Ho…

Trading off nutrition and education? A panel data analysis of the dissimilar welfare effects of Organic and Fairtrade standards
Millions of smallholder farmers in developing countries participate in different types of sustainability standards. A growing body of literature has analyzed the welfare effects, with mixed results. Yet, there are important knowledge gaps. First, most existing studies have looked at the effects of one standard in one country. When comparing between studies it is unclear whether dissimilar outcomes are the result of different standards or differen…
Land markets, Property rights, and Deforestation
We examine the emergence of land markets and their effects on forest land appropriation by farm households in Jambi Province, Sumatra, using micro-level data covering land use and land transactions for a period of more than 20 years (1992–2015). Based on a theoretical model of land acquisition by a heterogeneous farming population, different hypotheses are developed and empirically tested. Farm households involved in forest land appropriation dif…

Obesity trends and determinants in Indonesia
Obesity is becoming a serious issue in many developing countries, with negative implications for economic growth and human wellbeing. While previous micro level studies on obesity have mostly used cross-section data, we analyze trends and determinants with panel data from Indonesia. Over the past 20 years, obesity has increased remarkably in Indonesia across all population groups, including rural and low income strata. The problem is particularly…

The impact of agricultural biotechnology on yields, risks, and biodiversity in low-income countries
This paper shows that the current generation of transgenic crop varieties has significant potential to improve economic welfare in low-income countries. These varieties might increase crop yields in low-income countries in cases when pesticides have not been used. They will reduce negative health effects of chemicals when they replace them. With low transaction costs, appropriate infrastructure, and access to intellectual property, multiple varie…

The Impact of Bt Cotton on Poor Households in Rural India
The impact of genetically modified (GM) crops on the poor in developing countries is still the subject of controversy. While previous studies have examined direct productivity effects of Bacillus thuringiensis (Bt) cotton and other GM crops, little is known about wider socioeconomic outcomes. We use a microeconomic modelling approach and comprehensive survey data from India to analyse welfare and distribution effects in a typical village economy.…

Gender, agricultural commercialization, and collective action in Kenya
With the commercialization of agriculture, women are increasingly disadvantaged because of persistent gender disparities in access to productive resources. Farmer collective action that intends to improve smallholder access to markets and technology could potentially accelerate this trend. Here, we use survey data of small-scale banana producers in Kenya to investigate the gender implications of recently established farmer groups. Traditionally, …
