La gestion durable des ressources en eau est devenue le grand défi mondial du 21ème siècle. En effet l’accès à l’eau est essentiel à la stabilité des sociétés humaines et à la durabilité des écosystèmes. De plus en plus les responsables à tous les niveaux prennent conscience que la pénurie d’eau est susceptible d’entraîner des troubles politiques e...

The chapter provides an overview of the legal and institutional aspects of groundwater governance

Many agricultural production areas worldwide are characterized by high variability of water supply conditions, or simply lack of water, creating a dependence on irrigation since Neolithic times. The aim of this paper is to provide an overview of the evolution of irrigation of agricultural lands worldwide, based on bibliographical research focusing...

Drought is widely recognized as a slow creeping natural hazard that occurs as a consequence of the natural climatic variability. In recent years, concern has grown world-wide that droughts may be increasing in frequency and severity given the changing climatic conditions. Responses to droughts in most parts of the world are generally reactive in te...

The Near East region extends from Turkey in the north to Somalia in the south and from Mauritania in the west to Afghanistan in the east. It is characterized by aridity and scarcity of water which explains its dependence on irrigation since ancestral times. The aim of this paper is to give a brief overview of the history of water management and irr...

The presentation demonstrates the need for increased investments in agriculture water in the Near East Region and indicates the priority areas such investments should target

– With the most acute water-deficit in the world, the Near East Region challenge for economic and social development is likely to be jeopardized unless drastic measures are taken. The increasing need for water stems from population growth, national economies based primarily on agriculture and harsh climatic conditions and climate change that make r...

Water pricing policy is being increasingly recognized as a key instrument for improved water allocation, better conservation and quality preservation. It induces better demand management of water resources and is seen by many as the ultimate solution in water-deficit areas where supply is limited or cannot be augmented. The various uses of water...

La variabilite de longues series de precipita-tions est etudiee au niveau de differentes regions. L'etude a permis de degager que, meme quand les precipitations sont importantes, leur variabilite est tres accentuee. Elle a egalement permis de degager un certain nombre de modeles pouvant caracteriser cette variabilite. * Spatial and temporal variabi...

Different amounts of water are applied at 5 and 10 day intervals during the period when irrigation of sugar cane takes place and water is the limiting factor. The water balance method is used to measure sugar cane consumptive use and estimates of evapotranspiration using different empirical formulas are compared to the measured consumptive use in o...

Multidimensional spatial processes are often encountered when soil variables such as temperature and water and salt content are observed as a function of space and time. Time- or spatial-domain methods based on state-space models are useful for describing the movement of these series through space and time. The detection of important periodicities...

Soil surface temperature, measured on a 36-by-64 regular grid in a 6-hectare field, is modeled using two-dimensional spectral analysis and a signal-detection procedure. Temperature is found to behave randomly in one direction of the field (width), whereas the distribution in the other direction can be described as a superposition of four cyclic fun...

The effect of soil bulk density on soil water diffusivity and on infiltration is studied using data from 13 soils, widely ranging in texture. It is shown for horizontal infiltration of water into initially air dry soil that although changes in the slopes of plots of the distance to the wetting front as a function of square root of infiltration time...

This paper looks at water resources management from the perspective of being a tool for both preparation to and mitigation of drought. The focus is on water use in agriculture in the Near East region and elsewhere. It analyzes briefly past experiences and their success as well as shortfalls to achieve proper drought preparedness and mitigation, the...
