I genuinely don't understand how first-world countries manage to get into severe drought conditions in terms of potable water, and essential water for agricultural purposes.
In the UK for instance, we have had two years of spring drought in the south and yet, to coin a phrase `You need to grow webbed feet to live in the North West'. Climate may affect weather patterns and precipitation, but when an estimated 92k-litres of fresh rain water falls on the roof of every house in the Uk annually, and when you have land and technology to create reservoirs (and potentially a water grid ... thinks canal network upgrades), the issue is no longer one of the environment but becomes one of planning, investment and the will to plan and invest.
If nothing else this article proves that common sense is not common.
