Rangeland water requirement satisfaction index under rainfall variability and predicting future rainfall scenarios: implication for availability of feed resources
Introduction: Rangeland ecosystems provide multiple ecosystem services, including feed resources for wild and domestic herbivores in semi-arid areas. However, under the ever increasing environmental changes, the impact of rainfall variability on the productivity and vegetation dynamics of rangelands are the great challenges that pastoral community are facing today. As a result, the potentials o...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولAtmospheric warming induced changes in future rainfall and implications on water and agriculture in India
The projected rainfall change under various scenarios is likely to have both positive and negative implications on agriculture and water supply because in rainfall pattern across the country. Rise in rainfall is seen over all states except Punjab, Rajasthan and Tamil Nadu, which show slight decrease in precipitation in the future scenarios. Marked increase in covering the Western Ghats and nort...
متن کاملInvestigation of Rainfall Variability for Pakistan
Abstract Pakistan is an agricultural country mainly dependant on irrigation through the Indus water system. The country has developed the world’s largest contagious canal network. Monsoon precipitation is the lifeline of Pakistan which not only caters the national power supply and standing crops water demands but help gathers the reserves to meet the requirements of low flow period in the next ...
متن کاملKinetics of gravity-driven water channels under steady rainfall.
We investigate the formation of fingered flow in dry granular media under simulated rainfall using a quasi-two-dimensional experimental setup composed of a random close packing of monodisperse glass beads. Using controlled experiments, we analyze the finger instabilities that develop from the wetting front as a function of fundamental granular (particle size) and fluid properties (rainfall, vis...
