In Africa, there have been successes in cassava research in terms of the development of production technologies, particularly improved varieties with high yield potential. The study addresses the question of whether and to what extent adoption of improved cassava varieties has led to rural povert...

Non-farm activities have been generally considered as important strategy for overcoming credit constraints faced by rural households as well as for reducing poverty through income effect. This paper employs binary probit and average treatment effect to estimate the impact of participation in non-...


Dontsop Nguezet, Paul M.Manyong, Victor M.Abdoulaye, TahirouAlene, A.Amato, M.S.Ainembabazi, John H.Mignouna, Djana B.Okafor, C.[Non-farm activities and adoption of improved cassava and beans varieties in South-Kivu, DR Congo]Non-farm activities and adoption of improved cassava and beans varieties in South-Kivu, DR Congo

This paper investigates the determinants of adoption of improved cassava varieties in south-western Nigeria. The data come from a farm household survey of 841 households selected using a three-stage stratified random sampiling procedure. The data collection was conducted in 2011 by the Internatio...

Previous studies on the adoption and impacts of improved crop varieties have relied on self-reported adoption status of the surveyed households. However, in the presence of weak variety maintenance and poorly functioning seed certification system, measurement errors in self-reported adoption stat...

Achieving sustainable food security in Nigeria is feasible through organic farming. However, unavailability and resource constraints hamper the adoption of agricultural inputs; hence the market offers opportunity for use of purchased organic inputs. In assessing the importance of the market, the ...

This study explores the intra-household impact of improved dual-purpose cowpea (IDPC) from a gender perspective, in terms of productivity and food, fodder, and income availability, the impact of which is linked to the income thus placed in the women’s hands. Surplus income is important in providi...

Achieving sustainable food security and increased farm income will depend on how efficient production systems are in converting available inputs to produce outputs. Using data from Malawi, we estimate a Bayesian directional technology distance function to examine the relationship between farm siz...
