In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, hybrid...

In Senegal, one of the highest rice import-dependent countries in Sub-Saharian Africa, double cropping is recommended in the new national program for the Great Offensive for Food and Abundance (GOANA) to boost rice production. This target impels the respect of cropping calendar by using improved...

The article uses the Average Treatment Effect (ATE) to estimate the population potential adoption rates of New Rice for Africa (NERICA) varieties in Nigeria when awareness of the new varieties and access to their seed are not constrained to farmers. It thus extends previous works in the...

We apply a program evaluation technique to data obtained from rural Kenya to assess the patterns of adoption of improved pigeonpea varieties. The sample adoption rate of improved pigeonpea is found to be 36% while potential adoption rate is estimated at 48%. The adoption gap resulting from the...

This paper examines the informational origin of the low adoption rates of modern agricultural technologies in smallholder agriculture in sub-Saharan Africa. It argues that a large part of these low rates can be explained by the fact that many smallholder farmers are unaware of the existence of...

This paper shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random. It is proved that instead the sample adoption rate is a consistent estimate of the population joint exposure and adoption rate, which does not inform...

L’objectif de la présente étude est d’évaluer la diffusion et l’adoption des variétés de riz NERICA en Guinée cinq années après leur introduction. Les données collectées en 2002 sont relatives à 1535 paysans choisis dans 79 villages des quatre régions naturelles de la Guinée....

Rice sector contributes significantly to secure households with regard to their food needs but also to the creation of employments and income generation. The sector development and its evolution over the years have been marked by various policies and approaches. These development stages of the...

Collective actions groups have many advantages and are sometimes essential, yet they can reinforce or perpetuate inter-and intra-gender inequalities when their functioning is left entirely subject to internal community dynamics and they are not well managed. This is well illustrated by the case...
