“…An important challenge of the 21st century is the global water shortage that is exacerbated by droughts and rapid population growth [ Clarke , ; Cosgrove and Rijsberman , ]. Water shortages have led to increased reliance on groundwater, with subsequent broad reductions in groundwater resources [ Alley et al ., ; Konikow and Kendy , ; Leblanc et al ., ; Konikow , ; Scanlon et al ., ; Hejazi et al ., ].…”

Options for increasing reservoir storage in developed regions are limited and prohibitively expensive. Projected increases in demand call for new long‐term water storage to help sustain agriculture, municipalities, industry, and ecological services. Managed aquifer recharge (MAR) is becoming an integral component of water resources around the world. However, MAR faces challenges, including infrastructure costs, difficulty in enhancing recharge, water quality issues, and lack of available water supplies. Here we examine, through simulation modeling of a hypothetical agricultural subbasin in the western U.S., the potential of agricultural managed aquifer recharge (Ag‐MAR) via canal seepage and off‐season field irrigation. Weather phenomenon in many regions around the world exhibit decadal and other multiyear cycles of extreme precipitation. An ongoing challenge is to develop approaches to store greater amounts of water during these events. Simulations presented herein incorporate Ag‐MAR programs and demonstrate that there is potential to enhance regional recharge by 7–13%, increase crop consumptive use by 9–12%, and increase natural vegetation consumption by 20–30%, where larger relative increases occur for lower aquifer hydraulic conductivity and higher specific yield values. Annual increases in groundwater levels were 7 m, and sustained levels following several years of drought were greater than 2 m. Results demonstrate that Ag‐MAR has great potential to enhance long‐term sustainability of water resources in agricultural basins.

“…De hecho, el cambio discursivo del manejo del agua a la gobernanza del agua, en la última década, refleja un reconocimiento de la relevancia del agua a una gama más amplia de actores sociales (Conca, 2006;Nowlan y Bakker, 2010). Para ponerlo en los términos del World Water Council ['Consejo Global del Aguá], «el agua se ha vuelto el negocio de todos» ( Cosgrove, 2000). De acuerdo con esta perspectiva, tanto los académicos críticos como la sociedad civil han asumido el rol de explorar la naturaleza de la conexión entre la sociedad y el agua.…”

En este artículo desarrollamos el concepto del ciclo hidrosocial. Definimos el ciclo hidrosocial como un proceso socionatural, mediante el cual el agua y la sociedad se hacen y rehacen recíprocamente a través del espacio y del tiempo. Nuestro objetivo es presentar un concepto que servirá a los investigadores como un marco teórico y analítico para investigar las relaciones hidrosociales desde una perspectiva crítica.

“…Crop productivity and its water functions under the prevailing water shortage are among the first priorities of many researches in the world such as; [1][2][3][4][5]. [6] demonstrated that the consumptive use (ET) of 110 to 130-day sorghum crops range between 450 and 750 mm, depending on evaporative demand.…”

The present study was carried out at Sakha Agricultural Research Station (clayey soils) during 2018 and 2019 to find out the role of water deficit on yield and some water relations for sorghum and cowpea summer forage crops. Three irrigation levels were executed; 100% (full irrigation), 90% (10% deficit) and 80% (20% deficit). Results showed that increasing water deficit, markedly led to decreasing fresh, dry yield and plant height at the three cuts in the two seasons. Regarding water relations, irrigation level with 90% (10% deficit) resulted in several advantages; almost same yield as recorded under full irrigation, 10% water saving as well as the highest values of water productivity (WP) and productivity of irrigation water (PIW). The mean values of fresh sorghum forage yield can be arranged in descending order as; 2917.0 > 2857.5 > 2561.0 kg.plot-1, while the corresponding values of the dry weight were; 381.6> 367.8> 319.6 kg.plot-1. Plant height for cowpea slightly affected with different irrigation treatments. On the contrary, both fresh and dry yields were significantly affected with water level or deficit irrigation. Moreover, the effect was highly significant in connection with the combined analysis. In this regard, mean values of fresh yield descending arranged as; 1502.5> 1447.0> 1321.5 kg.plot-1 for treatments A(control), B (90%) and C (80%), respectively. The corresponding values regarding dry yield are 253.5, 241.0 and 215.4 kg.plot-1. Comparing the deficit treatments with the control irrigation (Trt. A), overall mean decrease in fresh yield was 3.7% for treatment B (90%) and 12% for treatment C (80%). While, the corresponding decrease in dry yield were 4.9% and 15.0%.We can conclude that forage yield of sorghum and cowpea not affect by water irrigation deficit about 10% at Middle North Nile Delta area.
