Development is a human problem and is aimed at changing man and his economic, social, ecological environment. Throughout history, man has acquired new knowledge to shape his future. As human needs multiplied and became more complex, science and technology – processes of systematic inquiry for...

A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50%...

The Multi-purpose Tree (MPT) species have the ability to fit into the farming systems of the East African region where low agricultural productivity, widespread land degradation and hence a diminishing capacity to support the growing human and livestock population are major problems. GIS has...

In developing country production environment, farm production efficiency is often measured in terms of on-farm resources and producer characteristics. In this paper we postulate that input and output market related factors also influence farm production decisions hence its efficiency. Stochastic...

Empirical studies on agricultural technology adoption generally divide a population into adopters and nonadopters, and analyse the reasons for adoption or nonadoption at a point in time. In reality, technology adoption is not a one-off static decision, rather it involves a dynamic process in...

Cattle rearing in humid west Africa was nearly impossible in the past owing to the prevalence of trypanosomiasis, a disease caused by the tsetse fly. However, in recent times, with population pressure, jungle clearance, crop cultivation and tsetse control measures, the challenge has been...

Stochastic frontier production function was used to assess technical efficiency and its determinants for a stratified sample of 1118 poultry farms in Vietnam for which data were collected in 1999. In general there are significant differences in the production behaviour and efficiency level...

Policy analysis matrix (PAM) was applied to assess the competitiveness of local, crossbred and exotic breeds of poultry and pig production in North and South Vietnam using data from a stratified sample of 2,213 farms collected in 1999. Results show that poultry meat and egg production is...
