This document summarizes and analyzes the Lesotho Highlands Water Project (LHWP) between Lesotho and South Africa. It makes two key arguments:
1) As theorized by Deudney, resource scarcity (water shortage in this case) can facilitate international peace by stimulating cooperation. The LHWP helped avoid conflict between Lesotho and South Africa over water access.
2) However, while the LHWP enabled international cooperation, it also intensified tensions within the two states by displacing communities and unequally distributing resources, indicating conflicts can emerge at the domestic level even when cooperation exists internationally.
