Competition for limited water supplies is increasing world wide. Especially hard hit are the irrigated crop production regions, such as the Lower Rio Grande Valley and the Winter Garden areas of south Texas. To develop production techniques for reducing supplemental water needs of vegetable crops, an ancient water harvesting technique called rainfall capture was adapted to contemporary, large scale irrigated muskmelon (Cucumis melo var. reticulatus L.) production systems. The rainfall capture system developed consisted of plastic mulched miniature water catchments located on raised seed beds. This system was compared with conventional dry land and irrigated melon production. Rainfall capture resulted in 108% average yield increase over the conventional dry land technique. When compared with conventional furrow irrigation, rainfall capture increased marketable muskmelon yield as much as 5355 lb/acre (6000 kg·ha-1). As anticipated,the drip irrigation/plastic mulch system exceeded rainfall capture in total and marketable fruit yield. The results of this study suggest that rainfall capture can reduce total supplemental water use in muskmelon production. The major benefit of the rainfall capture system is believed to be in its ability to eliminate or decrease irrigation water needed to fill the soil profile before planting.

This research was conducted through the rain season 2009 -2010, in Mehasseh Research Center at (Al Qaryatein), The area is characterized by a hot and dry climate in summer and cold in winter with an annual average rainfall of 114 mm. Three slopes (8%, 6%, 4%) were used in semicircular bunds water -harvesting techniques with bunds parallel to the contours lines at flow distance of 18, 12 and 6 m. The bunds were planted with Atriplex Halimus seedlings. Graded metal rulers were planted inside the bunds to determine soil loss and sedimentation associated with the surface runoff, and metallic tanks were placed at the end of the flow paths to determine agricultural soil loss from water runoff. A rain intensity gauge was placed near the experiment site to determine the rainfall intensity that produced runoff. The treatments were done in three replications. The amount of soil erosion (in tons per hectare per year) increased with increasing of the slope, the highest recorded value was 38.66 at slope of 8% and the lowest 0.05 at 4% slope. The amount of soil erosion also increased with increasing of water run distance, which was 38.66 T.ha-1.yr-1 at 18 m and 0.05 T.ha-1.yr-1 at 6 m . Bunds with different diameter of water harvesting reduced soil erosion by about 65% at slope of 8%, 55% at 6%, and 46% at 4%. The input parameters of Universal soil-loss equation were found to be suitable for determining soil erosion in this arid and semi-arid region.

Day By Day

Efficient use of water, one of the most critical life elements in the world, is becoming more and more important day by day. With the continuous increase in population and with climate change problems occur in terms of both consumption rate and usage patterns of water resources. It is becoming increasingly important to apply and research methods that can solve these problems all over the world. One of these solutions is the “Water Harvesting” method, which goes back many years. Water harvesting can be defined as the accumulation of runoff generated by precipitation to provide water for human, animal or crop use. While it is possible to see the use of the technique with roof and farm systems in micro-catchment dimension; wadi-bed and off-wadi (diversion) systems are used in macro-catchment dimension. In agricultural production, which uses a significant part of water resources, most of the rainwater falling into arid and semi-arid regions where production continues, goes away before could using efficiently by evaporation or flow. For this reason, the use of water resources becomes mandatory by using traditional irrigation methods in agricultural lands. With the water harvesting technique, after storing rain water, it can be held to be applied to crops. Hence the method since there will be no losses due to evaporation or flow, it will increase the total amount of irrigation water and reduce the pressure on water resources. Except for the protection of water resources, its role in preventing soil erosion is also seen as one of the main benefits of the method. In general, when the appropriate method is selected according to the appropriate geography, water harvesting has low inputs and is not difficult to apply. With a few exceptions, it does not require the use of pumps or energy input to deliver or deliver harvested water. In this study, information is given about the main elements, different usage areas and techniques of water harvesting.

AbstractMediterranean countries are still characterized by a great variety of historical cultural landscapes, as a result of the millenary human presence that has shaped the territory through agro-silvo-pastoral practices. In the arid regions of south eastern Tunisia, the land use is predominantly olive trees cropping and, because of the difficulties related to water scarcity, local population have developed a peculiar water harvesting technique ensuring the cultivation activities and minimising the risk from droughts. Jessour consist of small dams built across gullies and wadi thalwegs, creating a succession of terraces that partially retain the surface water and sediments required for crop growth. These structures are commonly built inside the watercourses to intercept runoff and sediments or at the foot of slopes. Considering that the biodiversity associated to traditional agricultural practices is important, especially in difficult environments, for ensuring food and nutrition to local communities, it results fundamental to preserve these peculiar practices. Moreover, taking into account that the presence of these water harvesting techniques allows the existence of a wide variety of flora and fauna species it result to be even more important to identify and maintain them from an ecological point of view. The research focused on the jessour identification and mapping in order to define their distribution nearby Douiret, in south of Tunisia, and describe the wide variety of species cultivated thanks to this traditional water harvesting solution. Moreover, using QGis software it was possible to analyse both jessour structure and peculiarities as well as their distribution according to the local morphological structure.

Abstract This article discusses the various water harvesting techniques used in the oases of Boussemghoun, Moghrar and Tiout for more than nine centuries. Several hydrological assessments have been conducted in the three oases since 2002 including surveys and investigations with the local communities. The results obtained showed that after the decrease in discharge of the sources, the population had resources to various ancestral hydraulic infrastructures such as: well, foggara, and small dams (Essad). The water harvesting technique is specific to the region and depends on the hydrogeology and the topography. Traditional low-flow water-saving technologies preserve the environment, modern hydraulic techniques give more water but have a negative impact on the environment. The drying up of springs and lowering of water tables are the result of the population growing and the socio-economic development. They require more and more water. A compromise between traditional and modern techniques (or types of management) can solve this problem.
