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

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%...

A dynamic bio-economic model is used to examine natural resource use, the resulting nutrient balances and economic outcomes in a poor country under a range of technological and policy intervention scenarios. With limited technological intervention over a twelve year planning period, incomes rise...

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...

Poverty, low crop and animal productivity and large-scale resource degradation are major problems in the agriculture sector in the East African highlands. Among others, integration of forage legumes in cereal based cropping systems has been proposed as a promising strategy to improve the...

Vertisols are important underutilized resources in the East African highlands because of their inherent waterlogging problem. In this paper, group experience in the design, development and diffusion of a technology package through farmer participation for improving management and productivity of...

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%...

Accurate assessment of farmers’ credit constraint condition is important in order to understand the circumstances under which credit would have its greatest impact. In this study a switching regression model was used to determine the impact of credit on smallholder dairy farms in the East...

This paper examines the theoretical and practical aspects of natural resource use in the poor tropics given limited technological and policy intervention. Results show that if farmers were to reallocate their land use activities based on land suitability, and utilize between 10-20% of their farm...

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...
