Water, water, everywhere…
Rain, rain, go away. Come again another day.
(Old English nursery rhyme)
Rain, rain, come back!
(New English nursery rhyme!)
With the hose-pipe ban in the UK my thoughts have recently been focused on water resources and drought. In Bavaria this is not really an issue, since many gardeners have their own well, and underground reservoirs ensure a safe water supply long-term. The reservoir near my hometown in England was, however, fairly low when I visited, and restrictions on watering are now in place in the south and east of the country.
Then I saw a TED Talk the other day which shows, among other things, what has happened to the Aral Sea on the border of Kazakhstan:
“Formerly one of the four largest lakes in the world with an area of 68,000 square kilometres (26,300 sq mi), the Aral Sea has been steadily shrinking since the 1960s after the rivers that fed it were diverted by Soviet irrigation projects.” (Wikipedia)
If you are short of time, just look at the photo on Wikipedia:
And if you have a few minutes, watch the whole TED talk here:
It looks at the whole issue of land and water in agriculture, and it really gets you thinking…
