The intrinsic link between the urban water cycle and climate variables, in particular rainfall, is forcing water supply managers to revise future water plans to incorporate the likely impact of climate change. However, there is great uncertainty surrounding how climate change will affect urban water security due to difficulties in projecting rainfall and the variability in rainfall projections ...
Climate variability poses a significant challenge for most of Africa, particularly given the continent‟s reliance on rain-fed agriculture. This uncertainty is aggravated by global climate change. We develop an integrated biophysical and dynamic economywide modeling framework that explicitly links uncertain future climate realizations to economic outcomes. Results for Zambia indicate that climat...
food security in the world that water shortages are faced is very important, especially in arid regions. effects of climate change on agricultural water requirement have doubled this importance. in this study, the risk of water demand has been assessed for a wide range of products under climate change. aogcm models have been used to simulate climate variables. the climate change scenarios of cl...
BACKGROUND Forests occur across diverse biomes, each of which shows a specific composition of plant communities associated with the particular climate regimes. Predicted future climate change will have impacts on the vulnerability and productivity of forests; in some regions higher temperatures will extend the growing season and thus improve forest productivity, while changed annual precipitati...
Effects of climate change on productivity of agricultural crops in relation to diseases that attack them are difficult to predict because they are complex and nonlinear. To investigate these crop-disease-climate interactions, UKCIP02 scenarios predicting UK temperature and rainfall under high- and low-CO(2) emission scenarios for the 2020s and 2050s were combined with a crop-simulation model pr...
Understanding the variations of streamflow of rivers is an important prerequisite for designing hydraulic structures as well as managing surface water resources in basins. An overview of the impact of climate change on the streamflow in the Hablehroud River, the main river of a semi-arid basin in north-central Iran, is provided. Using the LARS-WG statistical downscaling model, the outputs of Ha...
