The aim of this study is investigation of climate change impact on Karoon3 basin in future periods. For this purpose, the simulated precipitation and potential evapotranspirationof four AOGCM models was used to simulate drought index. Monthly precipitation was calculated by inverse distance weighted method. Reclamation Drought Index (RDI) was used as watershed drought index. RDI was calculated ...

climate change impacts on precipitation and temperature world-wide are not yet well understood (especially for precipitation), due to their complexity and regional variability. in this study in order to explicit the impact of climate change on precipitation and temperature in iran, 15 aogcm whose greenhouse gases scenarios ran under a2, a1b and b1 were used. monthly precipitation and temperatur...

due to the growth of industries and factories, deforestation and other environmental degradation a well as greenhouse gases have been increasing greenhouse gases on the earth's surface in recent decades. this increase disturbs the climate of the earth and is called climate change. an increase in greenhouse gases in the future could exacerbate the climate change phenomenon and have several ...

introduction today, climate change issue is one of the main challenges for scientists and due to the critical role of water in human life, the study of climate change impacts on severity and frequency of drought in each region seems to be indispensable (hulme et al., 1999). drought is usually occurred over a period of water shortage owing to less rainfall, high evapotranspiration and pumping a ...

The aim of this study is to investigate climate change impact on Karoon3 basin in future periods. For this purpose, the simulated precipitation of 10 AOGCM models, including BCM2.0, CGCM3T63, CNRMCM3, CSIROMK3.0, GFDLCM2.0, GISS-ER, HADCM3, INMCM3.0, IPSLCM4, MIROC3.2 MEDRES was used to simulate drought index. Monthly precipitation was calculated by inverse distance weighted method. Standard Pr...

Climate changes pose great threats to the main services of ecosystems such as food security, water security and health. This research was carried out in Haraz river basin rangelands, Mazandaran province in the north of Iran in 2015-2017 to analyze the perspectives of Haraz river basin (HRB) pastoralists about climate change. From 5236 local pastoralists, the sample size was consisted of 350 one...

India is the second largest producer of potato in the world. The Indo-Gangeticplains (IGP) is the main potato growing region accounting for almost 85% of the1.8 Mha under the crop in India where it is grown as an irrigated crop during thewinter season. Since IGP is in sub-tropical plains, duration of the thermally suitablewindow is the main determinant limiting yields. Hence the impact of clima...
