This paper outlines a general framework for analysing the distributional impact of commodity and factor price changes on the welfare of disaggregate households. The impact may be decomposed into an average effect and the departures from that average. The latter departures may be attributed to int...

Assessing the distributional impact of technical change in livestock and grains production in developing countries
New technologies must be developed in sub-Saharan Africa which are sustainable and economically viable. This paper discusses a methodology for measuring the agricultural sustainability and economic viability of tropical farming systems for new technology evaluation. The approach is based on the c...

Measuring the sustainability and economic viability of tropical farming systems: a model from subSaharan Africa
Most upland soils in humid and sub-humid tropical Africa are characterized by low inherent fertility and are also susceptible to soil erosion and compaction with cultivation. Based on simulation model, this study uses a capital budgeting approach to determine the profitability of alternative land...

10 years of livestock policy analysis. Policies for improving productivity, competitiveness and sustainable livelihoods of smallholder livestock producers
Using a household bioeconomic modelling approach, this paper analyses the impact of advancing in-kind credit in the form of fertilizer and seed on smallholder farmers with different levels of wealth in the Ethiopian highlands. Cropland allocation and household consumption patterns are examined in...

As human populations continue to grow, the intensification of agricultural production is occurring in order to maintain food consumption and rural income levels in developing countries. The demand for livestock products is generally income-elastic, so that, with increases in real incomes in most ...

Livestock-environment interactions under intensifying production
Agricultural intensification involving greater crop-livestock interactions and integration is emerging as the most promising strategy for improving agricultural production and productivity in much of sub-Saharan Africa. In West Africa, where this process is at various stages of evolution, 559 far...

Factors affecting farm-specific production efficiency in the Savanna zones of West Africa
The demand for livestock products in sub-Saharan Africa is increasing steadily. This demand is driven by human population, rural-urban demographic shifts and income growth. In sub-Saharan Africa, population is expected to increase from the present 500 million to nearly 1300 million in 2025. Urban...

Some evidence of encouraging changes in rural land and labour use systems that are indicative of evolving and perhaps sustainable agricultural production in Ethiopia is provided from a 1993 survey of 228 households in seven villages in the central Ethiopian highlands. Information is discussed tha...
