Cattle are one of the main instruments for economic (e.g., milk, meat, and cattle sale) and social (e.g., marriage, death, dispute settlement, and gift giving) exchange in Uganda. They serve as the main source of livelihood for a large majority of rural Ugandans, especially in the cattle corridor. Recent statistics demonstrate that the livestock sector contributes 13.1 percent of the agricultural gross domestic product (GDP) and 5 percent of the national GDP.

The climate change (CC) caused by increase in atmospheric concentration of CO2 and other Greenhouse Gases (GHGs), can be addressed through adaptation and mitigation strategies. Adaptation consists of strategies which minimize vulnerability to CC. The objective is to increase resilience of the ecosystems and communities through adoption of specific sustainable land management (SLM) techniques that have adaptive benefits. On the other hand, the goal of mitigation strategies is to enhance soil and vegetation (land) sinks for absorbing atmospheric CO2 and to minimize net emissions.

The economic value of the Upper Tuul ecosystem in Mongolia reports on a study carried out under the auspices of the World Bank and the Government of Mongolia. The goal of the study was to improve understanding about the economic value of the Upper Tuul ecosystem for Ulaanbaatar's water supplies and how this might be affected by different land and resource management options in the future.

Presents results of a study of grazing behaviour and forage resources utilisation by herded cattle belonging to agropastoralists at Abet & Kurmin Biri in the subhumid zone of Nigeria as well time spent on walking, resting & watering. Subdivides grazing activities into natural range grazing, browsing, grazing of crop residues and of burnt areas.

The study was carried out in Metema Woreda of Amhara National Regional State. The objectives of the study were to describe the goat production systems in the study area and to identify major constraints and opportunities of goat productivity; to evaluate the effect of supplementation with different protein sources on live weight gain of grazing goats under farmers management and to evaluate the economic feasibility of the feeding system under farmers condition.

In recent years governments and donor agencies have devoted considerable resources to efforts to improve the management of communal grazing lands. Range and livestock projects have been designed to address such familiar pastoral problems as endemic overgrazing of rangelands, often leading to permanent degradation of vegetation, soils, and water resources, and reduced livestock productivity, adversely affecting the welfare of rural people.

Extending livestock grazing to the steep slopes has led to unstable grazing systems in the East African Highlands, and new solutions and approaches are needed to ameliorate the current situation. This work was aimed at studying the effect of livestock grazing on plant attributes and hydrological properties. The study was conducted from 1996 to 2000 at the International Livestock Research Institute at Debre Ziet Research Station. Two sites were selected: one at 0-4% slope, and the other at 4-8% slope.

Livestock manure is an important source of nutrients for crop production in semi-arid West Africa. An assessment of the potential of manure to sustain crop production calls for an estimation of the amounts of manure that could be produced and captured and the feed resources required to maintain livestock used for manuring. This paper presents estimates of the amounts of manure produced by cattle, goats and sheep fed ad libitum under confinement. A model is presented to predict the yearly faecal output by grazing ruminants under fluctuating feed supplies.
