Global crop water consumption of green water resources  is projected to increase by about 8.5% by 2099 relative to 1971-2000 as a result of climate drivers , with additional smaller contributions by land use change  . In India, a substantial increase in green and blue water consumption is projected for wheat and maize, with a slight reduction of blue water consumption for paddy fields . Temperate drylands, especially higher latitude regions, may become more suitable for rain-fed agriculture . Locally and regionally, however, some of those areas with currently larger areas under rain-fed production, for example, in Europe, may become less suitable for rain-fed agriculture  .
