The countries of West Asia and North Africa (WANA) have long had the challenge of providing sustainable livelihoods for their populations in the fragile ecosystems of semi-arid and arid areas. Climate change is already a reality in WANA and it places additional constraints on the already fragile ecosystems of dry areas and limited natural resources in WANA. A comprehensive and integrated approach to planning and implementing the climate change adaptation strategies across the wide range of agro-ecosystems in different countries in WANA could help both the planners and the local communities to deal effectively with the projected impacts and also contribute to overall sustainability of agricultural production systems. This book addresses the important issue of climate change and food security in West Asia and North Africa and presents the appropriate strategies which could help in the development of new policies to better adapt agriculture production systems and enhance food security in WANA.

The Gulf Cooperation Council (GCC) is a political and economic union of Arab states, namely Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the Unites Arab Emirates. The GCC was formed in 1981 to strengthen the members’ economic, social and political ties by harmonizing regulations in various fields including economy, finance, trade and customs. The region extends over a territory of 2 673 108 km2 and is home to about 50 million people. The common denominators of the GCC countries are limited natural fertile land, scarce water resources and harsh climate. Depending on the country, the agriculture sector may use as much as 75 percent of the national available water resources. This has enormous environmental costs and significantly affects the sustainability of overall development in the Arabian Peninsula.According to Al-Rashed and Sherif (2000), the lack of renewable water resources is one of the critical constraints to sustainable development in the GCC countries. Rainfall in the Arabian Peninsula is scarce and infrequent. Over-exploitation of fossil groundwater resources, mostly to meet irrigation demands and create greenery lands, has already affected the productivity of aquifers, both quantitatively and qualitatively, despite the fact that much of the freshwater demand in the GCC countries is already covered using desalinated water. Reducing water consumption and increasing water efficiency are essential to enhancing agriculture and moving towards increased self-sufficiency with the production of high-quality, safe and diversified foods in the GCC countries. Exploiting the full potential of protected agriculture should save significant amounts of water, which can be used not only for agriculture but for other needs as well.

This book comprehensively introduces stripe rust disease, its development and its integral control. Covering the biology, genetics, genome, and functional genomics of the pathogen, it also discusses host and non-host resistance, their interactions and the epidemiology of the disease. It is intended for scientists, postgraduates and undergraduate studying stripe rust, plant pathology, crop breeding, crop protection and agricultural science, but is also a valuable reference book for consultants and administrators in agricultural businesses and education.
