This document compares two projects: the Orangi Pilot Project in Pakistan and the Gal Oya irrigation project in Sri Lanka.
The Orangi project involved local communities in planning and installing basic sanitation infrastructure without government funds. It promoted simple, affordable technologies and built local capacity through social organizers. The Gal Oya project aimed to increase rice production through irrigation but displaced indigenous groups and caused ethnic tensions by favoring Sinhalese settlers over Tamils. Both projects provide lessons about participatory development and whose interests are being served by different approaches.
