Abstract
The Rio Grande is 3,057 Km long with water sources from the Rocky Mountain
snowmelt, the Rio Conchos in Mexico and the Pecos River in Texas. It serves as
the only major source of surface water for two U.S. and five Mexican states, and
supports 5 million people. The Lower Rio Grande Valley is one of the most
productive agricultural areas in the U.S., generating roughly $ 500 million of
annual growth sales and accounting for approximately 85 percent of the region’s
water use. However, the population in the Basin is expected to double in the next
50 years causing doubled municipal water demands and serious agricultural
impacts. The Treaty of 1906 distributed the water between Mexico and the U.S.,
giving 74 million m3 per year to Mexico, while the Treaty of 1944 divided the
waters of the Lower Rio Grande and the Colorado River and stated the U.S.
should receive 432 million m3 of water per year from Mexico over 5 year cycles.
However, between 1992 and 2002, only half of the required water was delivered.
The water debt grew and Mexico currently owes 81.9 million m3. The future of
irrigated agriculture in the Rio Grande Valley is facing many challenges. The
Rio Grande Basin Initiative is focused on helping solve these rising problems by
implementing the following nine task groups: Irrigation District Studies;
Irrigation Education and Training; Institutional Incentives for Efficient Water
Use; On-Farm Irrigation System Management; Urban Water Conservation;
Environment, Ecology and Water Quality Protection; Saline and Wastewater
Management and Reuse; Basinwide Hydrology, Salinity Modeling and
Technology; and Communications and Accountability. This presentation
discusses the concerted results and outcomes from these tasks.
Keywords: efficient irrigation, water conservation, Rio Grande.
