Agricultural yields for farmers in sub-Saharan Africa tend to be lower than the rest of the world, and African farmers tend to use fewer productivity-enhancing agricultural technologies like fertilizer. This may be because of poor access to markets for farmers in remote rural areas, leading to higher delivered prices for inputs, lower net prices for output, and therefore, lower profitability of yield-enhancing technologies.
In Burkina Faso, as in many sub-Saharan countries, farmers struggle with low crop yields. Most established techniques to increase agricultural productivity rely on the use of technologies like fertilizer, but these inputs are expensive and inaccessible to many farmers in the region.
In parts of southern Africa, environmental pressure on the land from over-grazing has contributed to land and water shortages and made communities more vulnerable to drought. In Namibia, researchers are measuring the impact of a community-based natural resource management program on livestock assets, income, social cohesion and land quality.
Small farm productivity in sub-Saharan Africa lags behind that in Asia and other parts of the world. One reason for this may be low rate of adoption of inputs such as fertilizer. In Tanzania one reason for this may simply be the absence of local retailers, especially in more remote areas. Researchers are testing if their absence may be because of the costs of entering these markets or demand, with interventions targeted to each.
The agricultural sector in Sub-Saharan Africa has been changing in recent years, with more farmers living near urban areas, selling more of their crops for income, and also engaging in more off-farm work and non-agricultural activities to supplement farm revenue. However, little evidence exists thus far on how these trends are affecting nutrition, especially that of the most vulnerable members of farming families—women and children.
Farming is risky: a drought, bad harvest, or dip in crop prices can leave small farmers in developing countries without much-needed income. Attempts to mitigate these risks with agricultural insurance have typically been unsuccessful because farmers have chosen not to buy insurance. Researchers partnered with a large sugar cane company to see if delaying the premium payment until after the harvest would increase farmers’ demand for insurance.
Curbing deforestation in developing countries may be a cost-effective way to reduce carbon emissions and address climate change. Innovations for Poverty Action worked with researchers to evaluate the effectiveness of a payments for ecosystem services (PES) program, in which Ugandan landowners were paid not to cut forest trees on their property.
Seasonal hunger affects 300 million of the world’s rural poor. Seasonal migration can help some people find temporary employment, but many of those who could potentially benefit from migration face financial constraints that prevent them from traveling during the lean season. Researchers investigated whether providing low-cost travel incentives increases migration, and whether migrants experience better food security as a result of their travel.
Intensified use of agricultural inputs, particularly fertilizer, is a possible route to improved agricultural productivity. Evaluations of fertilizer use show substantial increases in yields, but they are typically done on highly monitored experimental plots rather than by farmers themselves.
Efficient targeting of public programs is difficult when the costs or benefits to potential recipients are unobservable. This study examined the potential of self-selection to improve allocational efficiency in the context of a program that subsidized tree planting in Malawi.
Adoption of agricultural technologies like fertilizer and improved seeds is low in African countries compared to other developing countries and evidence suggests that using these technologies can dramatically increase farm productivity and income. In an ongoing study, researchers are collaborating with One Acre Fund to examine the effect of credit and savings on the adoption of fertilizer and hybrid seeds, farm productivity, and farmer livelihoods.
In perfectly competitive markets, higher valued agricultural products should translate into higher prices, putting more money in the pockets of farmers. However, changes in value tend to reach producers at a lower rate in developing economies, which may be a result of the nature of the relationships between farmers and traders in this context.
The economic impacts of the Ebola virus required monitoring in real time for policymakers to estimate the short- and long-term costs of the epidemic and respond appropriately, yet information on the magnitude of the effects was scarce. The aim of this monthly survey in Sierra Leone was to measure the economic and social impacts of the outbreak on households and provide timely updates on the survey's findings to policymakers.
Researchers are testing whether access to improved-yield agricultural inputs and agricultural extension advice—when provided individually or in combination—leads to more intensive land cultivation and increased earnings among farmers in northern Ghana who receive access to rainfall insurance.
Many farmers in developing countries lack the capital necessary to invest in potentially profitable inputs, as these investments must be made months after the harvest when households lack cash. Commitment savings accounts, which have features to discourage withdrawals, have been shown to help the poor save, and could help farmers put aside money to invest in their farms. However, demand for these products is low.
