The United Nations General Assembly designated 22 March 1993 as the first World Water Day. Since then, World Water Day is held annually on 22 March as a means of focusing attention on the importance of water and advocating for the sustainable management of freshwater resources. The UN, its member nations, non-government organizations, and the public get involved to implementing UN recommendations and promoting concrete activities within their countries regarding the world’s water resources.
World Water Day is coordinated by a different UN agency each year. This year is the turn of the Food and Agriculture Organization. The theme is Water and Food Security, which aims to highlight the relationship between fresh water and food production. It can take 2,000 to 5,000 L of water to produce one person’s daily food. At all steps of the supply chain, from producers to consumers, actions can be taken to save water and ensure food for all:
- follow a healthier, sustainable diet;
- consume less water-intensive products;
- reduce food wastage: 30 % of the food produced worldwide is never eaten and the water used to produce it is definitively lost!
- produce more food of better quality with less water.
To celebrate World Water Day, ChemistryViews presents some of our recent, water-related content along with new articles on the topic.
