    The objective of this study was to model and analyze the influence Vallerani rainwater
    harvesting (RWH) structures have on the soil moisture dynamics in the Jordanian Badia
    and to test viability of these structures when influenced by climate change. HYDRUS-2D
    was used for the modelling. A three-month fieldwork was performed to set up and
    calibrate the model. The results show that most of the soil moisture is located
    underneath the furrow of the Vallerani RWH structures. The impact on water availability

    In the Mediterranean mountain areas of NW Syria, land degradation is a serious problem (Masri et al, 2005). Olive orchards dominate the landscape in Afrin area, and olive oil represents the most important cash income source for rural communities in this area. However, olive yields in many orchards have been decreasing steadily over the last 20 years. Low return to labour has resulted in livelihood insecurity, increased reliance on off-farm labour, and out-migration.

    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.

    MENA’s permanent cropland – currently at less than 6% of the total land area – is shrinking due to serious land degradation and recurrent droughts. The region faces the most severe water shortage in the world with annual renewable water resources per capita estimated to decline from 1,045 m3/yr in 1997 to 740 m3/yr in 2015.

    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.

    Jordanian rangelands are a source of valued livestock produce, carbon storage, biodiversity, and medicinal plants. They also serve as watersheds that receive rainfall, yield surface water, and replenish groundwater throughout the area east and south of the western Jordan highlands. Appropriate land management, which is currently lacking, can protect and maximize these services for society. With the acceleration of desertification, land degradation and drought during the twenty-first century in the arid and semi-arid regions of Jordan, these services are becoming jeopardized.

    The threat that the degradation of terraces in the highlands of Yemen poses to the livelihood of rural households and to national economic development has been widely recognized. The aim of this study was to contribute to the development of policy recommendations for the improvement of the life of rural families in the Yemeni mountains. Three small mountain watersheds (200-700 ha) in the northern, middle and southern mountain regions of Yemen were selected as the testing grounds for this study.

    Water scarcity and land degradation are widespread problems that affect agricultural productivity, food security and environmental quality in several parts of the world, particularly in the dry areas. Sustainable management of soil and water is necessary to optimize the use of limited rainwater for crop production and to decrease soil erosion. One management option is utilizing rainfall more efficiently through water harvesting. In arid areas, different types of water harvesting techniques (WHT) are being developed by
