The global water resource forecast predicts that the global crisis of water and environmental will take an unprecedented scale in the coming years with a significant increase in water deficit and an increased environmental degradation ( water pollution, drying up of rivers, desertification and salinization of soils, flooding and erosion of soils, reduction of forest areas, etc.).
Today, it is accepted by all that all regions of the world to varying degrees will not be spared by the impact of this crisis that affects all aspects of life (health, ecosystem, biodiversity etc.). ..).
Starting from the fact that:
The world's population has tripled in the 20th century and water needs have increased sixfold.
1/6 of the world's population does not have access to drinking water; 1/3 is not connected to sanitation systems.
07 million people die each year from water transmitted diseases.
Irrigated areas have increased fivefold during the past century and 70-80% of the world's eastern water is used in agriculture.
In developing countries, 70% of wastewater is discharged without any treatment into watercourses.
50% of the wetlands disappeared during the 20th century.
1/3 of the watersheds have lost up to 75% of their original forest area.
In front of this bitter report, the population of our planet has tripled since 1925. The damage we inflict on our environment are becoming more obvious. This situation could increase further in 2050 with the passage of the world population from 6 to 9 billion, as estimated by demographers. This population explosion would not be a concern if we do not consume the resources of our planet faster than they are formed.
The overconsumption of northern countries, coupled with the increase in food needs in southern countries, promotes soil degradation and premature depletion of natural resources, particularly water. Anthropogenic effects are beginning to be felt on the various elements of our environment (water, air, land and plants) which are now affected and modified in frightening proportions.
At the level of the Mediterranean basin, water is a scarce, fragile resource unevenly distributed over the different zones that make up the territories. The demand for water is continually increasing. Temporary or structural water shortages are noted. In addition to the tensions linked to the water resource, are added the degradations of the ecosystem and the biodiversity caused by the anthropic intervention and amplified by the water deficits.
Water and the environment have thus become a priority concern for sustainable development in this area; This is why the National School of Hydraulics (ENSH) as a specialized knowledge center devotes a significant part of its scientific activities to the handling of these issues. The theme of water and the environment has been the subject of an in-depth analysis since 1995 at the various seminars organized by the ENSH.
Research activities focus mainly on topics related to mobilization, improvement of distribution, rational use of the water resource, protection and preservation of the environment.
The question of the introduction of desalination technologies for seawater is a very interesting way forward. Certainly, able to significantly reduce the dependence of water needs climate hazards. This concern occupies a singular place in the research work developed by the School.
The results are published and widely disseminated through specialized structures and institutions, to prepare decisions to be made by policy makers to reverse trends and secure a better future for our natural resources.
The school is known for the quality of the product formed and put on the labor market. The lessons taught are in perpetual updating, taking into account innovations and scientific discoveries on the one hand and on the other hand the concerns and expectations expressed by users.
This specificity has become possible thanks to the available laboratories and equipments as well as to the rich and experienced teaching staff of the School, thus offering the student ideal working conditions.
Knowledge was and will remain an inexhaustible element in the service of its owner.
