There is concern regarding the loss of ecosystem goods and services as a result of land use changes such as the expansion and intensification of agricultural activities. Assessments of these interactions require innovative analyses that combine qualitative and quantitative economic analyses. The Millennium Ecosystem Assessment framework was applied to a peri-urban region in British Columbia, Ca...
Considering their contribution to global warming, the sources and sinks of methane (CH4) should be accounted when undertaking a greenhouse gas inventory for grazed rangeland ecosystems. The aim of this study was to evaluate the mitigation potential of current ecological management programs implemented in the main rangeland regions of China. The influences of rangeland improvement, utilization a...
Human-wildlife interactions are present wherever both humans and wildlife found. Interactions can be positive or negative for include impacts that range from damage to property, agriculture, health human safety, emotional effects. Livestock-wildlife form a major component of human-wildlife conflicts with foci often centered on the implications livestock predation by wildlife. While most vulture...
Land sharing, conserving biodiversity on productive lands, is globally promoted. Much of the land highest in California’s used for livestock production, providing an opportunity to understand sharing and species conservation. A review United States Fish Wildlife Service listing documents 282 threatened endangered California reveals a complex varied relationship between grazing According these d...
Occasionally foot and mouth disease (FMD) can be destructive of wildlife, as apparently occurred in South Africa in the late 19th century where large numbers of impala Aepyceros melampus succumbed, and more recently in Israel where high mortality occurred in mountain gazelles Gazella gazella (Macaulay, 1963; Shimshony, 1988). More usually, as is often the situation with domestic livestock in ex...
Cryptosporidium is an enteric parasite that is transmitted via the faecal-oral route, water and food. Humans, wildlife and domestic livestock all potentially contribute Cryptosporidium to surface waters. Human encroachment into natural ecosystems has led to an increase in interactions between humans, domestic animals and wildlife populations. Increasing numbers of zoonotic diseases and spill ov...
Kenya over the last few decades, and the change from a nomadic lifestyle to communally owned ranches, wildlife in the Samburu District is under threat from deforestation, land degradation, overgrazing by livestock, and unsustainable water use. Alexander Njue, who is also involved in a separate Earthwatchsponsored project studying the wildlife habitats in this area, hopes that wildlife can also ...
Identifying the ecological dynamics underlying human-wildlife conflicts is important for the management and conservation of wildlife populations. In landscapes still occupied by large carnivores, many ungulate prey species migrate seasonally, yet little empirical research has explored the relationship between carnivore distribution and ungulate migration strategy. In this study, we evaluate the...
Humans have never been healthier, wealthier or more numerous. Yet, present success may be at the cost of future prosperity and in some places, especially in sub-Saharan Africa, poverty persists. Livestock keepers, especially pastoralists, are over-represented among the poor. Poverty has been mainly attributed to a lack of access, whether to goods, education or enabling institutions. More recent...
The role of wildlife as important sources, reservoirs and amplifiers of emerging human and domestic livestock pathogens, in addition to well recognized zoonoses of public health significance, has gained considerable attention in recent years. However, there has been little attention given to the transmission and impacts of pathogens of human origin, particularly protozoan, helminth and arthropo...
