Wolves (Canis lupus) have expanded their distribution into areas of the midwest United States that have not had wolves for several decades. With recolonization of wolves into agricultural areas, there is increasing concern of wolf–livestock conflicts. To assess the risk wolves may pose to livestock, we initiated a 3-year study investigating the activity patterns, movements, habitat use, visitat...

Achieving water security remains one of the central challenges to many developing countries today. According South African Water Research Commission, availability safe and affordable is crucial in ensuring a healthy productive life for all. Despite national standards set measure quality Africa, sources ‘quality standards’ rural Eastern Cape remain major concern. Based on empirical research with...

natural resources have been attracted a great deal of attentions and have been frequently exploited for many years. dust is one of natural disasters mainly in recent years; here, in south west of iran, it had destroyed the rangelands. the dust has detrimental effects on the rangelands, livestock and livestock production. high concentrations of dust may lead to the coughing, nasal discharge, whe...

Mixed crop-livestock systems provide livelihoods for a billion people and produce half the world’s cereal and around a third of its beef and milk. Market orientation and strong and growing demand for food provide powerful incentives for sustainable intensification of both crop and livestock enterprises in smallholders’ mixed systems in Africa. Better exploitation of the mutually reinforcing nat...

The livestock sector contributes considerably to global greenhouse gas emissions (GHG). Here, for the year 2007 we examined GHG emissions in the EU27 livestock sector and estimated GHG emissions from production and consumption of livestock products; including imports, exports and wastage. We also reviewed available mitigation options and estimated their potential. The focus of this review is on...

Semi-nomadic pastoralism was replaced by sedentary pastoralism in Inner Mongolia during the 1960's in response to changes in land use policy and increasing human population. Large increases in numbers of livestock and pastoralist households (11- and 9-fold, respectively) during the past 60 yrs have variously degraded the majority of grasslands in Inner Mongolia (78 M ha) and jeopardize the live...

ABSTRACT- Overgrazing accelerates soil and vegetation degradation in rangelands. This study aimed to assess livestock pressure on natural resources of Khuzestan province, located in the south western part of Iran, using Geographic Information System (GIS) tools and a model-based procedure. FAO/UNEP Model which uses a ratio of potential carrying capacity of region to current liv...

A region is considered self-sustainable when the feed provision is adequate for all livestock demands. Livestock is fed in order to supply nutrient needs for maintenance, growth, and reproduction purposes. This study aimed to determine whether Madura Island inIndonesia is able to independently provide sufficient forage for its ruminant livestock. A Carrying Capacity Index (CCI) in four regions ...

Mixed crop-livestock systems, combining livestock and cash crops at farm level, are considered to be suitable for sustainable intensification of agriculture. Ensuring the survival of mixed crop-livestock systems is a challenge for European agriculture: the number of European mixed crop-livestock farms has been decreasing since 1970. Analysis of farming system dynamics may elucidate past changes...
