Climate Change: Water Scarcity, Hunger, Agriculture And Food

Water: we can’t live without it. Of course, people need it to survive, but water is also the throbbing vein of nature: vegetation, soil and lakes are dependent on fluids. Without water, our agricultural production and food security will collapse, and so will our nutritional security. That’s why we are facing an enormous problem: our freshwater resources are dwindling at an alarming rate. The UN reported that almost half of the population can be affected by water scarcity by 2050. Meanwhile, the world´s population keeps on growing, with higher living standards than ever before. How can we stop this growing water scarcity?

ZeroHunger

First, it is important to understand the extent to which water is used in our existence. Did you know, for example, that we consume much more water through the food we eat then what we drink? According to an article from the Food and Algriculture Organization of the United Nations, we need 2.000 to 5.000 litres of water to produce to food consumed daily by one person. The FAO has evidence that suggests that two-thirds of the world population could be living in water-stressed countries by 2025 if current consumption patterns continue. “To achieve a #ZeroHunger world by 2030, we need to take action now,” the organisation states.

Crops: choose it wisely

Agriculture is and will continue to be one of the main causes of water scarcity – one of the bigges, actually. The FAO states that farming accounts for almost 70 percent of all water withdrawals, and up to 95 percent in some developing countries. The choice for other crops is an answer to fight water scarcity because of agriculture, according to the FAO. For example, pulses crops have a small water footprint. For one kilogram of lentils, there is 1250 litres of water necessary, comparing to 13.000 litres for the same amount of beef.

Wastewater use to decrease the risk of famine

We are facing climate change. As a result of the warming global environment, more water will be needed to keep food production going. On the other hand, there will be more frequent and more serious droughts that will further increase water scarcity. The solution? According to FAO, we need to take action to harvest and recycle our freshwater reserves. We can use wastewater to decrease the risk of famine and socioeconomic disruption.

We have yet a lot to learn about the efficient use of water in are food value chain. According to FAO, “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”.

Food waste is water waste

Last but not least: food waste equals wasted water. To fight water scarcity, we have to fight wasted food. Let’s remember that if we throw away food, we also throw away the sources that made this food – water! According to FAO, “one-third of all the food produced is either lost or wasted each year — that translates into a volume of wasted water that is equal to around three times the volume of Lake Geneva”. The solution to foodwaste is simple: stop buying more than what you need. You can even go dumpster diving, to save the environment and some money!

As FAO says: “The issue of water scarcity is at the very core of sustainable development.” Without water, we can't grow our food. Fortunately, by changing our habits we can fight water scarcity.
