“…Private adaptation options to these impacts include agronomic practices such as conservation tillage or irrigation management (Olesen and Bindi 2002;Oweis and Hachum 2005). Increased competition for scarce water resources may promote the introduction of more efficient irrigation systems ).…”

This study links climate change impacts to the development of adaptation strategies for agriculture on the Mediterranean region. Climate change is expected to intensify the existing risks, particularly in regions with current water scarcity, and create new opportunities for improving land and water management. These risks and opportunities are characterised and interpreted across Mediterranean areas by analysing water scarcity pressures and potential impacts on crop productivity over the next decades. The need to respond to these risks and opportunities is addressed by evaluating an adaptive capacity index that represents the ability of Mediterranean agriculture to respond to climate change. We propose an adaptive capacity index with three major components that characterise the economic capacity, human and civic resources, and agricultural innovation. These results aim to assist stakeholders as they take up the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.

“…In the existing research, the technical improvement of rainwater harvesting is highlighted because the water yield from early rainwater harvesting techniques is insufficient for modern agricultural purposes (Hatibu et al 2006;Oweis and Hachum 2006). Technical improvement does effectively facilitate the operation of a new system, but does not determine its successful operation.…”

“…Many studies have pointed out that rainwater harvesting could effectively relieve the pressure of water scarcity (Helmreich and Horn 2009;Li et al 2000;Oweis and Hachum 2006). The farmers in places of water scarcity would have more incentives to use new water resources than the farmers located where there is water sufficiency.…”

“…The low amount of rain during the winter wheat growing seasons only provides 30% of the crop water requirements, and almost 70% of irrigation water is required to maintain the potential yield of winter wheat (Ouda, 2016). Long dry spells usually occurs during the critical growth stages i.e., flowering and grain filling which severely affect the final yield (Oweis & Hachum, 2006). The mean grain yield of wheat in this area ranges from 0.35 to 2 t/ha based on the rainfall amount and distribution, soil characteristics and used variety, which is a way far from the country average of 7.3 t/ha .…”

N ARID and semi-arid regions, the amount of rainfall and its …distribution greatly affect the productivity of crops in these regions. Rainfall deficits during the critical growth stages can cause a sever crop yield losses. The study was carried out at the agricultural Experimental station, Sustainable Development Center of Matrouh Resources, Egypt, during 2014/2015 and 2015/2016 rainfall seasons to evaluate the effect of different supplemental irrigation treatments on wheat yield . The irrigation treatments included rainfall only (control), one irrigation of 50 mm at tillering or booting or grain filling, two irrigations of 100 mm at tillering and booting or tillering and grain filling or booting and grain filling, and three irrigations of 150 mm at the three stages of tillering, booting and grain filling. The obtained results showed that the application of supplemental irrigation of 150 mm at the three stages of tillering, booting and filling secured the highest significantly values of plant height (61.47 cm), spike length (9.07 cm) and number of grains/spike (46.67) in the first season only, 1000 grain weight (39.72 and 48.53 g), biological yield (5.10 and 8.72 t/ha), grain yield (1.55 and 3.40 t/ha) , straw yield (3.54 and 5.35 t/ha) and WUE (0.672 and 1.08 kg/m 3 ) in both seasons, respectively. Wheat yield in the second season under the different supplemental irrigation treatments was simulated using the Root Zone Water Quality Model. Results showed a very good agreement between simulated and observed yields with a NashSutcliff Efficiency (NSE) of 0.93. It could be concluded that supplemental irrigation is highly important for achieving a good economic yield of wheat under the rainfed condition of Matrouh Governorate, moreover the RZWQM successfully simulated the wheat yield under water stress conditions.
