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

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...

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 ...


Assfaw Wossen, TesfamichealAlene, A.Abdoulaye, TahirouFeleke, S.Rabbi, Ismail Y.Manyong, Victor M.[Poverty reduction effects of agricultural technology adoption: the case of improved cassava varieties in Nigeria]Poverty reduction effects of agricultural technology adoption: the case of improved cassava varieties in Nigeria

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
Autor: Alene, A.

The question of whether the intended gains in food production from new varieties have actually been realized by poor farmers has received little or no attention in the literature. This paper used a stochastic frontier efficiency decomposition methodology to derive the technical, allocative and ec...

This article examines the magnitude and sources of yield variation among adopters of improved cowpea varieties in northern Nigeria promoted through farmer-to-farmer diffusion. The results reveal important efficiency differences between the lead farmers who have contacts with breeders and the foll...

Growing concern for poverty in the face of declining agricultural research budgets has increasingly required formal priority setting of public agricultural research in developing countries to ensure that scarce research resources are allocated in ways that will have the greatest impact on the poo...
