This E-Team is addressing the problem of agricultural water shortages in Malawi, in sub-Saharan Africa. Without irrigation, local farmers produce 200g of maize per capita, while baseline nutrition calls for 600g per person. This grant aims to further develop and refine the team's existing water pump, conceived, produced and tested between September '04 and March '06, in part with NCIIA funding. Following a visit to Malawi to test their prototype, the team optimized the design and investigated local manufacturing and distribution possibilities. They also distinguished their product from competitors by sourcing locally available parts, thereby ensuring that when pumps fail they can be repaired on-site, cheaply and quickly.
