Environmental resources and restraints to agricultural production in a mediterranean-type environmeAnalysis of the agro-climatology of the semi-arid and arid zones of the Near East has been undertaken by de Brichambaut and Wallén (1963), and Kassam (1981) reviewed the land resources and agricultural potential of the region. To complement these broad studies, this paper attempts a more detailed analysis for a few locations.

Water dynamics in the soil-plant-atmosphere system,The water problem in agriculture is related both to weather and to the reserves of water in the soil that are available to plants. Water dynamics in the soil-plant-atmosphere system concerns the capacity of the soil water reservoir, its depletion and replenishment, and its efficient management for crop production.

Optimizing the use of water and nitrogen through soil and crop management,Many factors limit crop production, e.g. diseases, insects, weeds, poorly adapted varieties, poor stands and nutrient deficiencies, but the major limiting factor is the supply of water. When there is little or no chance that the water supply will increase through irrigation or improved rainfall, one must learn how to use it more efficiently.

This paper reviews the climatic and soil resources in the region served by ICARDA within which the term ‘Mediterranean’ has been applied to a wide range of environments.

Modelling the interaction of water and nitrogen,esses which interact during the plants’ life cycle. In some cases, it may be obvious which growth factor is the major determinant of that final result. Especially in high intensity agriculture as practised in Western Europe, a state of ‘potential growth’ often exists where the available radiant energy during the growth period determines the yield.
