Level 1"The food systems of the future must deliver healthy and quality food for all, while preserving the environment.... We need to change our focus from producing more food to producing more healthy food" (da Silva, 2019, June 10)

From the opening address by United Nations Food and Agriculture Organization (FAO) Director-General José Graziano da Silva to the Future of Food International Symposium, Rome, 10 - 11 June 2019.

Future food | Water & aquaculture: Water use in agriculture

Background informationLevel 2Humans use a lot of water to grow our food. "We typically eat 500 times more water than we drink. "(Institute on the Environment, n.d.). The following image shows how much water is typically used to produce different foods. However, the amount of irrigation water consumed to produce a particular food depends greatly on where its grown. For example, a cow that eats hay watered with irrigation water uses more water than a cow eating rain fed grass. One big challenge to food system sustainability is to manage irrigation better to produce food in places where water is scarce." (Institute on the Environment, n.d.). See the following article for more details.

"Water is in short supply in much of the world - but what if we use seawater? It's been a dream for many years, but now technology is making it possible. This new seawater greenhouse uses a clever cardboard design to distill fresh water from salt water cheaply and efficiently. It's helping grow crops in Somaliland, and could help stop the water crisis in Africa and other parts of the world that are susceptible to drought. The founder of Seawater Greenhouse, Charlie Paton, explains how unlike traditional greenhouses - which are hothouses - this one is a "cool house" that is ideal for growing temperate crops in deserts or other hot, arid regions."
