Presentation
In this beginning of the XXI° Century, pressures exerted on water resources are increasingly strong because in particular of an increasing demand as well of quantitative and qualitative aspects. The generalization of drinking water networks in rural areas, extension of irrigated zones, diversification of agricultural products, urban explosion, industrial and tourist development are some of many factors which contribute to increase the pressure on water resources. Thus, research, exploitation and mobilization of more and more water resources, has become the first national priorities of many Mediterranean, Middle East and African countries.
In addition, in these areas, water resources are limited and characterized by a high temporal variability which is generated by the recurrence of drought over several decades. This aspect can be associated to many other aspects such as an unequal space distribution of these water resources, their overexploitation, the increase in water demand, the use of non-economic irrigation techniques, and the vulnerability of water resources to pollution and the impact of hydraulic installations.
These constraints are being reflected on the availabilities of water and thus encourage reconsidering the policies of water resources management. This management should be based on an integrated approach of water supply and demand. Installation of such strategy depends closely on the control of inputs and outputs at watersheds level.
The concept of integrated water resources management requires the use of both surface water and groundwater to satisfy the water demand for socio-economic development in many countries, but also the use of non-conventional water resources such as revalorization (recycling) of wastewater and desalinization of sea water and saline water and artificial recharge of aquifers.
However, despite all these efforts, no development can be qualified as sustainable if it is not operated with complete respect for natural resources in general, and water resources in particular.
This scientific meeting which comes following the first edition of 1st GIRE3D held in Marrakech, May 2006 and within sight of the success which knew this first edition, the congress will be an occasion for the different operators in the field of water resources management (researchers, decision makers, planners, laboratories, contractors, engineers and design departments, etc.) to present and exchange the results of their work around advances of new methodologies and new technologies for the improvement of integrated water resources management.
