Natural resource degradation and environmental damage are important concerns today. Through the influence of overgrazing, overstocking and feeding of crop residues, livestock have undoubtedly contributed to these processes. All too often, however, allegations about the detrimental impact of lives...

Inadequate feed and nutrition are major constraints to livestock production in sub-Saharan Africa. National and international research agencies, including the International Livestock Research Institute (ILRI), have developed several feed production and utilisation technologies. However, adoption ...

Livestock, especially ruminant, production is an important component of farming systems in upland areas of the Philippines. Moreover, since upland agriculture is becoming unsustainable because of soil erosion and productivity of crops is limited by poor soils, livestock production is a particular...

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...

The degree to which prevailing land tenure arrangements constrain agricultural productivity, and the sources of inefficiency associated with land tenure systems in sub-Saharan Africa are unresolved. Using a stochastic frontier production function, this paper examines the economic efficiency and t...

In Ethiopia smallholder livestock producers have adopted components of improved dairy technologies but the intensity of adoption remains low. It is hypothesized that credit-related constraints limit the ability of many smallholder farmers to make investments in crossbred cows and/or to purchase c...
