This study developed and employed a socio-economic-ecological-modeling (SEEM) framework in its analyses. The SEEM is made up of four resource use domains of highlow population density and highlow access to market and two agro-ecologies in the savanna of Nigeria. Data used comprises a sample of 32...

Agriculture in the dry savannas is intensifying in response to increasing populations of humans and livestock. As a result, increased productivity demands are placed upon integrated crop-livestock systems and more emphasis is on the roles of legumes such as cowpea. Cowpea has the potential to fun...

Phosphorus is important for cowpea production in many tropical African soils with inherent low P fertility. Most farmers in Africa, however, do not have access to P fertilizer. Selection of cowpea lines that produce good yield under low soil P or those with high P-use efficiency can be a low inpu...

The potential impact and return to investment from introducing improved dualpurpose cowpea for food and fodder in northern Nigeria was investigated using a combination of farmers' workshops and village and household level surveys. Out of the 462 households surveyed, 41 % were adopters, 9% had bee...

The Guinea savannas of Nigeria have a high potential for the production of maize because of favorable environmental conditions. Despite this high potential, the yields obtained under farmers' conditions are still very low. Low soil fertility and intermittent drought are among major constraints li...
