Livestock production may account for 30% of all water  used in agriculture  and can negatively affect water quality. Cropland feed production accounts for 38% of crop water consumption . High-input livestock systems may consume more water than grazing or mixed systems, though water used per kg beef produced, for example, depends on country, context and system . In systems where feed production is rainfed, livestock and crop water productivity may be comparable . Direct water consumption by livestock is <1-2% of global water consumption . Rising temperatures increase animal water needs, potentially affecting access of herders and livestock to drinking water sources .
