Ferro-cement Lined tanks are in-ground storage tanks made of cement and iron wire mesh. They collect water from low-flow and intermittent sources, and are typically pumped into header tanks for irrigation purposes. If the tank is built at a higher elevation than the field (up a hill, for instance), a pump may not be required to extract the water. These tanks can support daily irrigation of fields up to 2,000 square meters, or can support a smaller field through a dry period.
iDE is an international non-profit dedicated to ending poverty in the developing world not through handouts, but by helping farm families access the tools and knowledge they need to increase their income.
iDE's origins as a formal organization lie in a visit to a Somalian refugee camp in 1982. It was there that founder Paul Polak noticed a critical lack of transport limiting the economic opportunities of refugees who were relying on manual transportation for all commodities. Following the principle "in technology, simplicity is the ultimate sophistication," iDE re-engineered the local donkey cart and interested local artisans in manufacturing one with a more efficient center of gravity, using abandoned car parts for affordability. The donkey carts were a success; more than 500 were sold, producing $1 million of net income for cart owners.
