    Asia and the Pacific, for the purposes of this book, encompasses a vast territory extending from Mongolia in the north to New Zealand in the south; from the Cook Islands in the east to Kuwait in the west (Map 1). The environmental diversity of Asia and the Pacific is therefore vast, and is contrasted by the region’s coldest and hottest deserts, verdant tropical rainforests, extensive steppe, desert steppe, grassland and rangelands, mountains and plains.

    Dryland mountains are among the least-known environments in the world, and certainly one of the most overlooked by decision- and policy-makers. Dryland mountains have an outstanding strategic value. They act as water towers for surrounding dry lowland areas, as shown by the examples of the Rocky Mountains of North America, the Central Andes, the mountains of the Mediterranean Basin, the Sahara and Sub-Saharan Africa, West Asia, and Central Asia

    This report is a documentation of data gathered during the project for the Badia Benchmark, organized in a way to facilitate the on of various disciplines. The purpose is, to facilitate the use of this data for better management of resources during the project and to provide accessible and user friendly database that is suitable for use beyond the project lifetime. It is anticipated that future research and development projects, will build upon this database and continue the documentation to enhance the use of data for the Badia and similar areas.

    The Central and West Asia and North Africa (CWANA) region encompasses large areas of arid and semi-arid zones. These zones may be defined as areas where rainfall, relative to the level of evapotranspiration, is inadequate to sustain reliable crop production. Most of the arid and semi-arid zones of the CWANA region are rangelands and are characterized by wide variability in rainfall and temperature. Droughts are common, resulting in low forage production and crop productivity as well as water scarcity.

    Mechanized construction of micro-catchments for water harvesting (WH) was successfully tested in the Badia (dry rangeland) areas in Syria and Jordan, using the “Vallerani” plow, model Delfino (50 MI/CM), manufactured by Nardi, Italy. The plow was able to construct intermittent and continuous contour ridges, and could potentially be used to rehabilitate degraded rangelands. However, one major issue for large-scale implementation is the high cost and time required to manually identify contours for the plow to follow.

    CropSyst is the crop growth model chosen as a decision tool for the Tadla Benchmark project. CropSyst is a daily time step simulation model. The model was developed to serve as an analytic tool to study the effect of cropping systems management on productivity and the environment. The model simulates the soil water budget, soil– plant nitrogen budget, crop canopy and root growth, dry matter production, yield, residue production, and decomposition. Management options include cultivar selection, crop rotation, irrigation, nitrogen fertilization, tillage operations, and residue management.

    The rangelands of West Asia and North Africa are the grazing grounds for the Bedouin with their flocks of sheep, goats and camels and are known as al Badia in the Middle East region. Average annual rainfall in the Badia ranges between 50 and 250 mm (Haddad 2006). Despite its scarcity, rainwater is generally poorly managed and much of it is lost through runoff and evaporation. To improve production in hese areas, there is a need for the sustainable management of natural resources – land and water (FAO 1983).
