‘Water Is Essential for Agricultural Production and Food Security’; Yet ‘Freshwater Resources Are Dwindling at an Alarming Rate’

2. Climate Change

Water scarcity is expected to intensify as a result of climate change. It is predicted to bring about increased temperatures across the world. More frequent and severe droughts are having an impact on agricultural production, while rising temperatures translate into increased crop water demand.

In addition to improvements in water-use efficiency and agricultural productivity, we must take action to harvest and reuse our freshwater resources and increase the safe use of wastewater. Doing so will not prevent a drought from occurring, but it can help in preventing droughts from resulting in famine and socioeconomic disruption.

3. Food Loss and Waste

Wasted food equals wasted water! When we waste food, we are also wasting the resources that went into producing it. Each year, one-third of all the food produced is either lost or wasted — that translates into a volume of wasted water that is equal to around three times the volume of Lake Geneva.

We can all make small changes in our daily life to reduce our food waste, from using our leftovers to shopping only for what we need.

4. Food systems

Water is often used inefficiently in the food value chain. In addition, key decisions such as site selection, technology and suppliers are frequently made without taking into account the impacts on water resources, especially when water is not a limiting factor either in quantities and/or in price.

FAO is working with countries to ensure water use in agriculture is made more efficient, productive, equitable and environmentally friendly. This involves producing more food with less water, building resilience of farming communities to cope with floods, droughts and the ever-changing climate, and applying clean water technologies that protect the environment.

The issue of water scarcity is at the very core of sustainable development. It comes down to the fact that we simply can’t grow the food we need if we don’t have enough water! We need to change our habits and act now to protect this precious resource. It is one of the most important ingredients to achieve a #ZeroHunger world!
