THE NATIONAL WATER RESERVE PROGRAM: A MEXICAN EXPERIENCE IN IMPLEMENTING ENVIRONMENTAL FLOWS

In 2012, Mexico launched the National Water Reserve Program (NWRP) to implement environmental flows (e-flow) as a nationwide strategy for freshwater conservation. The NWRP is based on the premise that leaving enough water for nature sets the foundation for long-term water availability for all uses, and an adaptation strategy in the face of a changing climate. Water reserves (i.e. e-flows) were determined by applying holistic and hydrological methodologies described in the National Environmental Flow Standard. A multidisciplinary team coordinated by WWF and Mexico’s National Water Commission, analyzed field information through different conservation scenarios and the risk of different alternatives for water resource management, to adopt a preventive allocation of water for the environment. Water reserves in nearly 300 river basins have been established through presidential decrees, representing the conservation of 55% of the total country’s surface water. Of the total volume of reserved water, 79% is destined to ecological conservation, 1% to human consumption to cover population needs by 2070, and only 20% is available for new uses. The NWRP represents an advance in interdisciplinary research and multi-stakeholder coordination showing that ecosystem conservation and water management are two compatible practices.
