Supermarkets and high-value exports are currently gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on farming efficiency have hardly been studied. Using a survey of Kenyan vegetable growers and a stochastic frontier approach, we show that participation in supermarket channels increases mean technical efficiency by 19%. This gain is bigger at lower levels of efficiency, suggesting the potential for positive income distribution effects.
It is now widely acknowledged that biotechnology will have significant implications for development. While biotechnology’s potential for low income economies is still the subject of controversy, this paper argues that it is precisely in these countries that food and agriculture related biotechnology could efficiently contribute to the achievement of development objectives. To date, however, biotechnological advances have been realized predominantly in industrialized countries.
Most micro-level studies on the impact of agricultural technologies build on cross-section data, which can lead to unreliable impact estimates. Here, we use panel data covering two time periods to estimate the impact of tissue culture (TC) banana technology in the Kenyan small farm sector. TC banana is an interesting case, because previous impact studies showed mixed results. We combine propensity score matching with a difference-in-difference estimator to control for selection bias and account for temporal impact variability.
This paper considers genetically modified (GM) seed adoption decisions by farmers in a developing country under two alternative information regimes (with and without perfect information regarding production conditions) that allows the monopolist producer of GM seeds to either practice perfect discrimination or uniform pricing. Under each regime we analyze two scenarios: when the government can and cannot credibly commit to the announced form of welfare enhancing intervention in the domestic seed market.
The UNDP Strategic Plan 2018-2021 recognizes the global importance of sustainable commodities to achieve the SDGs. This Guidance Note is designed to assist UNDP Country Offices in programming and policy support for national sustainable agricultural commodity projects. The Note is based on UNDP’s environmental, poverty, governance, finance and private sector work on sustainable commodities and their supply chains.
