Header bags are used to supply water to a drip irrigation system. They are suspended above field level by a locally-made platform or frame. The higher they are suspended, the greater the pressure that will feed the drip system. Header bags were designed to replace more expensive buckets or tanks, which can be twice as costly. Header bags are also easier to store and ship, as they are made from a collapsible plastic exterior with an interior plastic liner. Each bag can hold approximately 200 liters (53 gallons) of water.
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.
