Freshwater is becoming an increasingly precious commodity. In the near future, control of it could lead to the type of political instability that is now associated with energy shortages.

This book addresses the different aspects of irrigation, including not only the management of water resources and scientific and technical aspects but also matters related to policy and economics. The objective of the Conference Series is to provide a venue for an international presentation and dissemination of papers related to sustainable ways of conducting irrigation.

Sustainable irrigation has three key aspects, i.e.

i) developing ways of using scarce water resources most efficiently to maximize food production while minimizing the environmental impact of irrigation activities on the affected land and water resources;

ii) ensuring that the extraction of water from surface and groundwater sources is set at sustainable levels to maintain healthy aquatic ecosystems to secure a continued supply of quality water for irrigation, recreation and urban/industrial uses;

iii) facilitate an equitable distribution of the water available for consumption between competing users, which is essential to maintain sustainable communities.

Attracting researchers in academia and industry, as well as professional practitioners and policymakers, the Third International Conference provided a platform for a review of the state of the art from the scientific, technological, political and economic points of view. Papers from the Meeting are published in this volume, and cover the following topics: Irrigation Management; Modelling and Simulation; Sustainable Irrigation – Farmers’ Actions, Environmental Benefits and Socio-economic Consequences
