Displaying 1 - 2 of 2Contour Laser Guiding for the Mechanized “Vallerani” Micro-catchment Water Harvesting Systems
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.
Performance and Adaptation of the Vallerani Mechanized Water Harvesting System in Degraded Badia Rangelands
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.
