The challenges of irrigated agriculture

Irrigated agriculture produces over 40% of the world's food on less than 20% of cultivated land.

Irrigation consists of acting on the natural water cycle to manage and secure crops in geographical contexts where rainfall is either insufficient or random. It is essential for global food security, which is subject to geographical challenges.

However, there are many challenges to sustainable irrigated agriculture if we are to meet current and future needs: integrated water resource management, social equity for farmers with regard to land and water allocation, the economic and financial viability of irrigated systems, water governance and appropriate institutions, water saving and wastewater reclamation, agroecological practices to reconcile productivity with environmental and climatic challenges, and the preservation of biodiversity, are all dimensions that must be taken into account.
