Share 2 good BBC documentary on Reforestation in China & Afrcia, Rwanda .
Part 1 of BBC Documentary: Reforestation in China
http://www.youtube.com/watch?v=BjGYFhMRjfE
Overgazing & overfarming in Lus plateau [near Si Cuan], have caused servere land degradation. When the land is stripped of vegetation, water washes away top soil which further degrades the land till the land becamea barren area.
Restoration Effort :
1. Stop animal-grazing / Stop farming on the land.
2. Plant vegetation. Build terrance to retain water.
3. Vegetation will slow down water flow.
When enough vegetation grows, streams will form.
More water encourage more vegetation which retains more water [positive cycle]
In 3 to 5 years the land would be restored.
The local community would benefit as they can then farm the land and gain food security. :>
Part 2 of BBC documentary: Reforestation in Afrcia Rwanda.

Reforestation in Africa Rwanda restored barren land to one full of vegetation.These protects the wetlands which ensures that enough water can flow to drive the hydro power-station downstream.
The documentary ends with a meaningful question: "Since we can restore the degraded land in China & Africa, which brings vegetation back to the land, and secures the future of the local people [as they can then farm on these lands], Why don't we reforest ALL the degraded land in the world? "
Surely we can do that :>:):>
The restored land can also sequece much CO2 in the soil.
That will be a BIG help in the fight against Climate change.
