I saw a documentary the other day where Beavers were introduced to some south American country sorry can't remember which country or why they were introduced. The gist of the story was they the beavers had become a nuisance causing flooding because beavers do what they do best and that is dam rivers. In this particular case they were running amock because they didn't have any natural predators. I would also guess that the locals don't know how to deal with beavers. A beave will only dam and cut trees if he hears running water so if you install sumberged slanted pipes or some such thing which there are lots of examples the beaver will only cut enough wood and sapplings to feed himself. I guess it is a natural inborn instinct to stop anything that sounds like running water. Remove the sound he stops building.

Tonight I was listening to short wave some South African country reception was bad but they were saying how a famine was looming if the rains didn't come soon. The affected areas were the East coast of africa and ivory coast.

Having been to Eritrea and Ethiopia I have a little experience with their landscape at least in that area.

I have blogged about this before how I and the locals were impressed and hopefull about the possibility of salt water irrigation.

That is the reason for this blog though. I got to thinking about the landscape, and it occured to me that there were lots of river beds where I was but more often than not they were dried up and only saw water during the rainy season. So how to retain this water for the rest of the year without entailing astronomical costs involved with man made dams? BEAVERS

You might say it is to hot for beavers in Africa but according to the experiment in South America it shouldn't be. Because it would seem they thrived and actually worked to well at retaining water.

Just a thought.

Update:
It wasn't a documentary it was a news clip on Global and while this particular story is negative in nature with reference to introducing beavers to a foregn land I still think the benefits for the South African drought prone areas would far out weigh the negatives.
