This paper addresses the problem - with increasing values of land, crops and livestock in the semi-arid region, what happens to the livestock component? The conventional wisdom is that abundant land in more remote areas is more conductive to livestock Development than where human population densi...

Five mathematical models were evaluated for their ability to describe ruminal degradability profiles of protein sources composed of herbaceous legumes, browse species and oilseed cakes. Degradability constants of dry matter, organic matter, nitrogen and neutral detergent fiber of the feeds were t...

Animal trypanosomosis is particularly important in Ethipia where 7-10 million cattle are at risk. A geo-referenced census of over 5000 households was conducted between March and July 1996 to better understand factors affecting demand of the a cypermethrin pour-ons used since January 1991 to contr...

Since 1986 the Joint Vertisol Project (JVP) which involved a number of national and international research and Development institutions in Ethiopia gave high priority to developing alternative management practices for increased and sustainable food and feed production in highland vertisols. The J...

To understand the environmental impacts of controlling trypanosomosis, there are two principle questions to answer: 1) How does controlling trypanosomosis affect the pattern and rate of land-use/land cover change? 2) If these changes occur, how do they affect ecosystem structure and function? For...

In the Sahel, opportunistic resource management operates with communal access rights and land tenure systems that include particular access rights and land tenure systems that include particular access rights to key pastoral resources. The pastoral Development approaches attached to the concept o...

Cross bred cow adoption is an important and potent policy variable precipitating subsistence household entry into emerging bulk markets. This paper focuses on the design of policies that create and sustain milk-market expansion among a sample of households in the Ethiopian highlands. In this cont...
This document describes the process for developing strategic priorities for inclusion in ILRI's medium term plan for 1998-2000. It indicates the rationale for quantitative ex ante assessment of program impacts, the method to be followed, the time and resources required, and the people involved in...

The note is divided into five parts, viz, sampling methods, multicollinearity or intercorrelation, autocorrelation, and estimable and testable functions. The first part discusses sampling procedures, sample size determination, random sampling, sampling by deliberate stratification, blocking and i...
