Studies of rainfall variation generally focus on large areas. For example, in India, the area average monsoon rainfall series of the whole country or meteorological subdivisions are used. This would be of no use for local agriculture, particularly in places where rainfall is very high or very low, especially for crops like small cardamom and vanilla which are very sensitive to soil moisture and...

The world’s arid lands are some of the most beautiful landscapes on Earth, and their paucity of vegetation often makes it possible to see landforms and structures with great clarity (Figure 1.1). In addition, they have many characteristics both in terms of landforms and geomorphological processes that render them different from other major environments (see, for example, Laity, 2008; Parsons an...

Understanding nitrous oxide (N2O) fluxes from agricultural soils in semi-arid regions is required to better understand global terrestrial N2O losses. Nitrous oxide fluxes were measured from three rain-fed, cropped soils in a semi-arid region of south-western Australia on a sub-daily basis from 1995 to 2014 using automated chambers. Western Australia’s grain-belt includes 7 million hectares of a...

More accurate forecasting of monthly rainfall is significantly important in drought forecasting in agriculture, irrigation schedule, water resources management, and crop pattern design. In this paper, ability of time series models in forecasting the rainfall according to the climate conditions is estimated. For this purpose, rainfall data of four different climates in Iran was selected. Using t...

Water scarcity is one of the factors limiting plant growth and development. More than onethird of the global terrestrial ecosystems is located in arid and semi-arid regions. The mostimportant limiting factor for plant growth is water shortage. Drought could significantlychange the natural vegetation cover. Rainfall reduction in Iraq, Turkey and Syria hasreduced vegetation cover so that dust sto...
