Research in India found that a combination of climate-related stresses on sheep - for example, excessive heat and lower nutritional intake - had severe impacts on the animals' biological coping mechanisms (Sejian et al., However, projected drier conditions in the extensive rangelands of southern Africa would increase water scarcity, in Botswana, the costs of pumping water from boreholes increases 23 percent by 2050. In the Near East, declining forage quality, soil erosion and water scarcity will most likely be exacerbated in the semi-arid rangelands (Turral, Burke and Faures, 2011). In Europe, global warming is likely to increase sheep tick activity, and the risk of tick-borne diseases, in the autumn and winter months (Gray et al.,
