Managing the endangered Rio Grande River across the U.S.-Mexico border
Consensus solutions for an international quandary
Nava, a native of Mexico who did her Ph.D. in international studies in Canada, made an extensive analysis of documents and case studies related to the Rio Grande/Bravo water management practices and policies. She conducted two rounds of fieldwork and 77 interviews with people across the Rio Grande/Bravo basin, asking them about their perceptions and interests related to the river.
“The interviewees included water managers in Colorado; pecan farmers, water engineers and managers, researchers, citizens, and environmental groups in New Mexico and Texas; and water managers, members of the academia, and environmental groups in Mexico: basically anyone who relies on the river or cares about it. We wanted to cast as wide a net as possible because these are the people who know the river — who better than them to talk about the existing problems and the potential solutions,” says Nava.
Based on the perspectives and interests gathered through the interviews and analysis, Nava and colleagues proposed four policy recommendations that could help strengthen water resources management in the region:
- Allow for reciprocal and temporary water re-distribution, meaning that during times of drought, water could be moved from one purpose to another. For example during a drought it might make economic sense for a farmer to transfer their water to another use, like city or municipal use or fish farming. Such a scheme would allow them to temporarily transfer their water right to another willing user, who would give them back their water in times of water abundance.
- Take better advantage of the many experts in the region, and bring them together to work and communicate among themselves.
- Formulate small-scale strategies to reach sustainability across the basin. For example this could mean, for the region above Elephant Butte Dam in New Mexico, strengthening efforts to restore native habitats and protect the forest. For the region between Elephant Butte Dam to El Paso, Texas it could mean removing sediments in the river and to bring it alive even during the non-irrigation season. And for the binational stretch of the river, to agree on a common interpretation on water quality related issues that need to be solved.
- To reach a binational agreement for the Rio Grande/Bravo, adapting the scope of the 1944 treaty to account for pressing current problems and future challenges.
IIASA Water Program Director Simon Langan says that the Nava’s work confirms the increasing importance of global drivers such climate change, population growth, and ecosystem health, at the regional level. He says, “This study adds to and complements the growing global recognition of the importance of water and the potential for increasing conflict where increasing demand for water exceeds supply. Nowhere is this more important in significant transboundary river basins where there is an urgent need to recognize and develop wider participation aimed at building consensus on solutions for future water management.”
