Bien qu’étant une des ressources les plus essentielles pour toute vie sur Terre, l’eau douce ne représente que 3% des ressources d’eau de la planète, et seulement 0,5% de cette eau douce est facilement accessible aux humains.

ICARDA continued to play a critical role in the development, improvement, and dissemination of climate-resilient crop varieties last year. The varieties strengthened food and nutritional security and provided a critical defense against extreme temperatures, water scarcity, and the emergence of new pests and diseases.
Estimating the potential land resources suitable for irrigation and evaluating the possible impact of climate change on land suitability is essential for planning a sustainable agricultural system.
A reliable supply of water is critical for agricultural intensification and yield improvement. Technological devices that lift, transport and apply water contribute to increased yield from improved crop varieties and high input cultivation. The increasing use of motor pumps is a significant contribution to the development of small-scale irrigation.
This publication provides conceptual material for use in the preparation of national regulations for the management, development, use and protection of freshwater resources. The conceptual material is arranged according to the principal functions of water resources management, and it is complemented and illustrated by examples of original water management regulations.
