Check out this great initiative carried out in Pemba, Zanzibar by Community Forests International:

Pembans have built massive rain water storage systems, wired solar micro-grid, and worked alongside nature to grow over 1,000,000 trees spanning 30 different species!  Now we want to help expand these innovative approaches and technologies and share them far and wide.  Join with us, as we take rural innovation to the next level.
