Abstract
Close relationship between the hydrological cycle and climate system there. Water resources to reduce Middle East with regard to global climate change will be. Iran country and consequently Middle East in the semi arid region located in arid and water resources are limited. Runoff, river discharge, groundwater, flood and drought are all strongly influenced by rainfall, one of the most important elements are among climate, accommodation. In this paper, relying on staff information (IPCC) and obtaining information from relevant agencies to assess the effects of climate change on water resources, water crises in the Middle East and paid for Analytic Research enmity - are documents, the purpose of research, of climate change in recent years the Middle East and prevent the water crisis in Iran. Also provide part of the results of studies done on temperature and precipitation changes that indicated increased fluctuations in temperature and precipitation is in the country, the possible effects overset balance between the country’s climatic and hydrological systems, including increased flooding due to rainfall and temperature, changes in water levels of lakes and above all competition between water needs will be referred.
Highlights
Climate change and wide fluctuations in the overall climate of a region that is Earth’s temperature warming trend as part of climate change are considered
Climate change and possible effects on the distribution of rainfall, runoff and underground water table is fed, so that you cannot assume that the future pattern of hydrological phenomena such as past [3]
The report states that the rich countries are facing water shortages
Summary
Climate change and wide fluctuations in the overall climate of a region that is Earth’s temperature warming trend as part of climate change are considered. Climate change is one of the biggest environmental challenges facing the world today. Rising world temperatures that weather patterns can change rising sea levels and changing weather on the eve of the consequences of climate change is causing non-uniformity be distributed rainfall affects on water resources. Water Resources of the Middle East issue is no exception and the lack of water supply in future will face consecutive droughts and the growing demand for water as well as the broad challenge of water scarcity in the region, especially Iran focuses on. According to FAO in more than 80 percent of models to estimate climate change, precipitation in the region over 40 mm per year will be reduced [1]. The world’s average annual rainfall of 833 mm square, while the amount in some parts reaches to 50 mm
