In the end the long-term health of the whole Lowveld ecosystem including Kruger will depend on how the main rivers running through the area are managed and protected.
South Africa have some of the best water acts/laws in the world but the issue comes in with the implementation of these laws...
My hope is that one day our government will realise how vital healthy rivers are to the future of our country and that competent and passionate people will be appointed to enforce these laws.
At the moment the situation doesn't look so positive however... I guess it is also up to us normal citizens to help create awareness about these issues and also to be public watch dogs on this matter.
Just think if we can have a strong flowing Letaba river all year round again!
Cleaner and stronger flowing rivers will also have many positive spin-offs in Kruger that we don't always think about.
For instance, even more man-made waterholes could be closed which will help restore more natural animal distribution patterns and help re-awaken age-old migration routes.
Of course there are initiatives such as the Kruger to Canyon movement which specifically focus on the catchments of the Olifants and other low veld rivers.
I would be very interested to hear from some forumites that are involved in this, on how that initiative is going?
