In the Sindh deserts of Pakistan, the water situation is desperate:  some women walk for four hours to collect water for their family.  Fariel Salahuddin has an answer to the problem though, GOATS!  There are a lot of goats in the desert, every family has a goat or three, but money is scarce.  So, villagers club together, each providing a goat or whatever they can spare and Fariel and her friends sell them for during Eid when the price is high.  The money is used to pay for solar water pumps to provide water for drinking, bathing and cooking.  Perhaps the biggest impact though, is on society:  families are happier and the villagers are socialising more.
