    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.

    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).

    Rainwater harvesting in micro-catchments such as contour ridges and semicircular bunds is an option for utilizing the limited rainfall, improving productivity and combating land degradation in dry rangeland areas (Badia). However, implementation of this practice using manual labor or traditional machinery is slow, tedious and costly, and often impractical on a large scale. These limitations can be overcome using the ‘Vallerani’ plow for quickly constructing continuous and intermittent ridges.

    The shortage of water in arid zones represents the most serious obstacle to poverty reduction because it limits the extent to which poor producers of crops and livestock can take advantage of opportunities arising from emerging markets, trade, and globalization. Water shortage in arid zones limits the variety and quantity of crop and livestock products a smallholder can produce, thus narrowing their range of options.

    The Badia constitutes about 90% of the total land area of Jordan, which is 89 342 km2. Its average annual rainfall is < 200 mm. The area with annual rainfall of 100–200 mm is considered the promising rangeland for rehabilitation. The Badia (part of the rangeland) supplies the livestock sector with about 20% of forage needs, while all the other sources provide the sector with only about 5% of forage.

    This will ensure more sustainable ecosystems and improved rural livelihoods. Emphasis is given to building on local knowledge by using existing data, social capital, research linkages, partnerships and proven methodologies and technologies in the region thereby ensuring the sustainability of the impacts achieved. The Initiative also draws from a wide pool of multi-disciplinary expertise from within and outside the region and targets the three major agro-ecosystems in the region – rainfed, irrigated and rangeland.

    How suitable an area is for WH depends on local society, farming practices, and whether the area meets the basic technical requirements of the WH system in question. When planning such systems, appropriate data must be available on the climate, soil, crops, topography, and socioeconomics of the project area. The available tools and methods of data acquisition for planning, designing, and implementing WH systems, include field visits, site inspections, topographic and thematic maps, aerial photos, satellite images, and geographic information systems (GIS) must also be considered.

    This report will focus on results of 2004/05 and 2005/06 seasons in which the conventional handmade microcatchment was compared to the mechanized one through research done at the Jordan University of Science and Technology site.
