Water Rights and Water Fights: Resolving Conflicts Before They Boil Over (APHA, 2009) [Abstracts of five presentations given at APHA’s 137th Annual Meeting, Philadelphia, 7−11 November]
Abstract of the presentation Water rights and water fights: Resolving conflicts before they boil over − An overview: As the world's population grows from 6.5 billion people now to 9.0 billion by 2050, as countries modernize, and as climate change evolves, there will be increasing conflicts, including armed conflicts, over the finite supply of fresh water. Already, during the past two decades, there has been a substantial increase in the number of international and intranational conflicts, many of them violent conflicts, over water. This presentation will describe the nature of these conflicts and provide specific examples and also describe the application of international and national laws, diplomacy, mediation and arbitration, and other approaches for resolving these conflicts before they boil over. These approaches may provide a basis for resolution of other issues that might otherwise lead to armed conflict.
