Human and livestock evacuation during volcanic crises is an essential component of volcanic risk management. This study investigates the evacuation of human and livestock populations from areas impacted by ashfall from the 1991 Hudson eruption, Patagonia. The eruption was one of the largest in the 20 century resulting in significant impacts on rural communities in affected areas, including the ...

Livestock production is a key income source in eastern Africa, and 80% of 22 the total agricultural land is used for livestock herding. Hence, ecological and 23 socio-economically sustainable rangeland management is crucial. Our study aimed at 24 selecting operational economic, environmental and social sustainability indicators for three 25 main pastoral (P), agro-pastoral (AP), and landless in...

Biodiversity in rangelands is decreasing, due to intense utilization for livestock production and conversion of rangeland into cropland; yet the outlook of rangeland biodiversity has not been considered in view of future global demand for food. Here we assess the impact of future livestock production on the global rangelands area and their biodiversity. First we formalized existing knowledge ab...

One way to use the timber resources of our country more efficiently is to convert the refuse from logging and manufacturing operations into food. Research at the Forest Products Laboratory therefore is aimed in part at the conversion of wood to sugar solutions, which have been tested as livestock feed by several agricultural experiment stations. The investigations indicate that w^ood wastes can...

OBJECTIVES Administration of antibiotics to food animals may select for drug-resistant pathogens of clinical significance, such as methicillin-resistant Staphylococcus aureus (MRSA). In the United States, studies have examined prevalence of MRSA carriage among individuals exposed to livestock, but prevalence of multidrug-resistant S. aureus (MDRSA) carriage and the association with livestock ra...

Crop diversification and integration of livestock into cropping systems may improve the economic and environmental sustainability of agricultural systems. However, few studies have examined the integration of these practices in the semiarid areas of the Northern Great Plains (NGP). A 3-yr experiment was conducted near Bozeman, MT, to compare the effects of crop rotation diversity and weed manag...

A key risk factor for climate change is the growth in the human population, projected to be about 35 per cent between 2006 and 2050. In the same period the FAO projects that the number of livestock worldwide will double, as will their emissions, while it is widely expected that emissions from other industries will drop, they say. “This would make the amount of livestock-related emissions even m...

Use of livestock guardian dogs (LGDs) to reduce predation on livestock is increasing. However, how these dogs influence the activity of wildlife, including predators, is not well understood. We used pellet counts and remote cameras to investigate the effects of free ranging LGDs on four large herbivores (eastern gray kangaroo, common wombat, swamp wallaby, and sambar deer) and one mesopredator ...

The introduction of domestic livestock particularly sheep and rangeland grazing by Norse settlers to Faroe during the 9th century has generally been described as a major pressure on a sensitive landscape, leading to rapid and widespread vegetation change and contributing to land degradation. This view has, however, been developed without consideration of Norse grazing management practices which...
