Population growth, increasing demands for food, ever-growing competition for water, reduced supply reliability, climate change and climate uncertainty and droughts, decline in critical ecosystems services, competition for land use, changing regulatory environments, and less participatory water resources governance are contributing to increasing difficulties and challenges in water resource management for agriculture and food. These problems vary from small to big and are different for different countries all over the world. Water is essential for agricultural production and food security. Food sovereignty puts sustainability and justice first, rather than seeing them as optional add-ons we somehow can’t afford.

An integrated view on water, the biosphere and environmental flows is required to devise sustainable agricultural and economic systems that will allow us to decelerate climate change, protect us from extremes and to adapt to the unavoidable at the same time. Agriculture is a term that refers to farming, which can include growing crops and raising animals in order to produce food. The water used by plants is nonrecoverable, because some water becomes a part of the chemical makeup of the plant and the remainder is released into the atmosphere.
