Global scale climate–crop yield relationships and the impacts of recent warming
Changes in the global production of major crops are important drivers of food prices, food security and land use decisions. Average global yields for these commodities are determined by the performance of crops in millions of fields distributed across a range of management, soil and climate regimes. Despite the complexity of global food supply, here we show that simple measures of growing seaso...
متن کاملActual impacts of global warming on winter wheat yield in Eastern Himalayas
Himalayas, are among the areas most vulnerable to global warming, however, little is knownabout warming impacts on the crops. Therefore, the actual affects of anticipated warming onwinter wheat were tested in Tibet, China. During the period 1988-2012, Tibet region hasexperienced a large increase in daily mean, minimum and maximum temperatures during wheatgrowing seasons by 0.50, 0.67 and 0.51 o...
متن کاملClimate change impacts on crop yield: evidence from China.
When estimating climate change impact on crop yield, a typical assumption is constant elasticity of yield with respect to a climate variable even though the elasticity may be inconstant. After estimating both constant and inconstant elasticities with respect to temperature and precipitation based on provincial panel data in China 1980-2008, our results show that during that period, the temperat...
متن کاملClimate change impacts on crop yield, crop water productivity and food security – A review
This paper provides a comprehensive review of literature related to the assessment of climate change impacts on crop productivity using climate, water and crop yield models. The existing studies present that climate change models with higher spatial resolution can be a way forward for future climate projections. Meanwhile, stochastic projections of more than one climate model are necessary for ...
متن کاملWarming puzzle for Tibetan plants
and its tourist industry, a new report, commissioned by the UN Development Programme, with British and Caribbean partners, highlights the threat to other tropical islands. Released at the Cancún meeting, it estimates in detail the impacts of rising sea level on the 15 member Caribbean states of the Caricom regional community. While many of the islands are mountainous, the report highlights that...
