We obviously need water to survive, and no human rights without survival. Inadequate water supplies also cause diseases, violating our right to health. We need water – and clean water – to drink, but also to eat. Or rather, to produce our food. And we need a lot. People drink on average just a few liters a day, but they consume thousands of liters a day if we count the water required to produce their food. And evidently we should count it. Many areas of the world face already now face water shortages. A fifth of the world’s population already lives in areas short of water. A global water crisis waits around the corner, and one likely consequence is famine, another human rights violation.
If we want to do something about the water crisis, we should be aware of the effect of food production on water shortages. Especially the production of meat requires huge amounts of water, compared to the production of grains or even rice. People in the West eat a lot a meat, and therefore contribute substantially to water shortages. As incomes in the developing world increase, people there will consume more meat. Hence, global water consumption will also increase. Combine this future increase with the fact that there are already shortages and that these shortages will get worse with global warming, desertification etc., and you get a real crisis.
What are the solutions? Or how can we prevent things from getting worse?
- Jokingly we could ask people to become vegetarians. That would also be better for greenhouse gas emissions, by the way.
- More realistically: food production, and especially agriculture and farming, represent 70% of global water consumption. That number could be cut down significantly with better irrigation; “more crop per drop”. There’s incredible waste going on there. 70% of irrigation water is lost in the process. One reason: farmers rarely pay their water bills at market prices, hence no incentives to cut waste. Unfortunately, pricing water at market prices would drive up food prices, pushing many consumers into poverty. And many poor farmers already can’t pay for expensive irrigation systems. More expensive water surely wouldn’t help them. Moreover, market prices may mean the privatization of water, and that’s dangerous. You might as well privatize oxygen.
- Other solutions: cut waste in households and industries. Here, everyone can help. Also more recycling efforts are needed. Desalination, although expensive, is an option. As are better water storage facilities, especially for poor families in developing countries. All these efforts will not only reduce the risk of a major global water crisis, but will also improve crop yields, thereby reducing the price of food and hence the risk of poverty and famine.
