Water Management - Water for people and for agricultural production

The importance of integrated management policies, models, and tools to ensure availability of fresh water for people and for agricultural production.

The earth has 1.4 billion cubic Km of water, but only 0.001% of this blue expanse is actually available for human consumption. In addition, the allocation of water resources at a planetary level is strongly uneven and imbalanced towards the agricultural sector, which absorbs approximately 70% (compared to 22% used by industry and 8% used at a domestic level).

Therefore, water is a scarce resource, even if renewable. As stressed by the World Bank, we can contain it, channel it, collect it, purify it, package it, transport, and transform it, but we cannot “produce” it. Water scarcity in 2025 will likely be dramatically worse than it is today: an increase in world population will result in an increase of agricultural activities and domestic use, so that between 15% and 35 % of current water collection for irrigation will not be sustainable in the future.

This simple observation leads to a complex truth: managing and controlling water resources and their use is one of the greatest overall challenges that we face today on a global scale.
