The international locations of West Asia and North Africa (WANA) have lengthy had the problem of supplying sustainable livelihoods for his or her populations within the fragile ecosystems of semi-arid and arid components. weather swap is already a fact in WANA and it locations extra constraints at the already fragile ecosystems of dry components and restricted ordinary assets in WANA. A accomplished and built-in method of making plans and imposing the weather swap variation concepts around the wide selection of agro-ecosystems in numerous nations in WANA may well support either the planners and the neighborhood groups to deal successfully with the projected affects and likewise give a contribution to total sustainability of agricultural construction platforms. This e-book addresses the real factor of weather swap and nutrients protection in West Asia and North Africa and provides the perfect recommendations that may assist in the advance of latest guidelines to higher adapt agriculture construction structures and increase foodstuff defense in WANA.

Reduction of precipitation of 10–20 % (IPCC 2007a) is expected and runoff by 40 % in many areas (FAO 2010) is predicted. 5 °C surface temperature by the end of the twenty-first century and this increase would be coupled with a projected decrease in precipitation from 0 % to 20 %. These projected changes mean shorter winters, dryer and hotter summers, a higher rate of heat waves, a higher level of climate variability and more frequent extreme climate events. The nature of the impacts of sea level rise will vary from place-to-place and is due to a variety of factors, depending on local conditions such as elevation of the land and geological land subsidence.

It is a high priority for the region to install monitoring and early warning systems for impending disasters and to develop disaster preparedness plans for meeting any threat to food supplies and agriculture output. It is also important to enhance capacity for prevention of disasters and reduction of its impacts including trans-boundary plant and animal diseases. Enhancing institutional and technical capacities in monitoring and assessment of climate change impacts is another area of urgent action.

The agricultural productivity of most crops exhibited noticeable increases during recent years. This increase was observed in limited areas due to irrigation and improving management practices. On the other hand, the majority of the countries in WANA have serious problems in increasing cropping options and crop diversification largely due to water scarcity; and to some extent agricultural diversification as a result of limited economic resources, low levels of technology, and environmental limitations (Abou-Hadid 2009).
