Mignouna, Djana B.Abdoulaye, TahirouAlene, A.Manyong, Victor M.Dontsop Nguezet, Paul M.Ainembabazi, John H.Asiedu, Robert[A microeconometric analysis of household consumption expenditure determinants in yamgrowing areas of Nigeria and Ghana]A microeconometric analysis of household consumption expenditure determinants in yamgrowing areas of Nigeria and Ghana

The Yam Improvement for Income and Food Security in West Africa (YIIFSWA) project was initiated to assess and understand yam-based systems in order to identify the opportunities of interventions that could potentially help to increase productivity in the region. The project consists of two phases...

This paper evaluates the impact of an emergency research for development project implemented in the Democratic Republic of Congo from 2000 to 2009 by a various actors including the International Institute of Tropical Agriculture in response to the outbreak of the Cassava Mosaic Disease that threa...


Rusike, J.Mahungu, N.M.Lukombo, S.S.Kendenga, T.Bidiaka, S.M.Alene, A.Lema, A.Manyong, Victor M.[The impact of the emergency response to the outbreak of the cassava mosaic disease in the Democratic Republic of Congo]The impact of the emergency response to the outbreak of the cassava mosaic disease in the Democratic Republic of Congo

Sustainable agricultural intensification requires the use of multiple agricultural technologies in an integrated manner to enhance productivity while conserving the natural resource base. This study analyses the adoption and impacts of sustainable intensification practices (SIPs) using a dataset ...

This paper measures the technical, allocative, and economic efficiencies of farmers within and outside the Extension Package Program (EPP) in high and low potential agro-ecological zones in eastern Ethiopia. Within-group farmer efficiencies are analyzed relative to respective technologies to exam...


Alene, A.Hassan, R.M.[Efficiency of food production under old and new technology: the case of farmers within and outside the Extension Package Program in Ethiopia]Efficiency of food production under old and new technology: the case of farmers within and outside the Extension Package Program in Ethiopia

We use DNA‐fingerprinting to estimate the poverty reduction effect of adoption of improved cassava varieties in Nigeria. We estimate the counterfactual household income distribution of cassava producers by combining farm‐level treatment effects with a market‐level model. Our results suggest that ...

Cowpea covers the largest area of any grain legume in Africa and is especially important in West Africa where Nigeria and Niger alone account for over 75% of the total cowpea production in the world. Despite successes of international and national cowpea improvement research in the development an...


Manda, J.Alene, A.Hirpa Tufa, A.Abdoulaye, TahirouKamara, A.Olufajo, O.Boukar, O.Manyong, Victor M.[Adoption and ex-post impacts of improved cowpea varieties on productivity and net returns in Nigeria]Adoption and ex-post impacts of improved cowpea varieties on productivity and net returns in Nigeria

A translog stochastic production fronter was used to analyse the technical efficiency of small farmers using improved maize production technology in Western Ethiopia. The study estimated a mean technical efficiency for the entire sample of 76%, indicating that a significant potential for gains fr...


Alene, A.Hassan, R.M.[Determinants of farmlevel technical efficiency among adopters of improved maize production technology in Western Ethiopia]Determinants of farmlevel technical efficiency among adopters of improved maize production technology in Western Ethiopia

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...
