With the help of our friends at Solar Energy International (SEI) and Lakota Solar Enterprises (LSE), students installed a solar water pump at our recent Sustainable Agriculture and Solar Water Pump Workshop. Powered by a solar array, the pump pulls water from the nearby creek and feeds into a gravity drip-irrigation system to water our garden at Solar Warrior Farm. Now that is sustainable!
The training also included an overview of drip irrigation systems and vermicomposting with John the Worm Man. Thanks to everyone who made this training a success!
Sustainable Development, Sustainable Livelihoods 
I am doing a research project on Pine Ridge, SD and Agriculture Production and Food Security. This post was most helpful and I hope to learn more about what is being done to combat the problem of extreme poverty. I am hopeful of changes that are happening. Thank you for posting.
