Resumen : In the region of the Low Segura River Valley, in the southern area of the
Alicante province, the reduction in irrigation water availability and the political
debate draw a difficult situation for agriculture. During recent years, as a result
of the application of the National Irrigation Plan, irrigated areas are being
modernised, improving their irrigation network infrastructure. But, for
modernisation to go beyond isolated or point measures, it should spread through
all procedures that allow the Water User’s Associations comprehensive
management and control of irrigation water. The work presented here aims at
analysing and quantifying the problems and needs perceived by some WUAs
about irrigation. A survey was made by a 76 items questionnaire structured in
four main topics: i) WUA identification and general information; ii) aspects
related to decision making and management processes; iii) services for members
provided by the WUA, and iv) future perspectives and improvement

Resumen : Climate change scenarios in Mediterranean basin point to a decrease in the amount of annual rainfall and the increased frequency of drought. In this framework of greater water scarcity, an increase in irrigation costs is expected, so its rational and efficient use is an unavoidable issue in modern irrigated agriculture. In the last 60 years in Portugal, it had a great increase in the efficiency of water use in agriculture, accompanied by a great increase in energy consumption, and the variation was 15,000 to 6000 m3/ha.year and 200 to 1500 kWh/ha, respectively. The rational application of fertilizers is a priority, to prevent the contamination of superficial and subterraneous waters, and the process of soil salinization in semi-arid conditions. The pressure of
water demand by agriculture implies the use of other water sources. For example, in 2010, the volume of unconventional water resources in Spain rose to 4.540 hm3/year.
Of the total used in agriculture, 450 hm3 of water comes from the reuse of treated water, and 690 hm3 comes from desalination. The use of modern/smart technologies in irrigated agriculture, like information and communication technologies, allows the rapid share of information between all the system components and can promote optimized answers at different scales.2024-02-05T12:34:28Z
