4. Contributions
• Mexican standard of environmental flow
(Norma Mexicana de Caudal Ecológico)
• Identification and feasibility analysis of water
reserves
5. Water Reserve
National Water Law:
– Art. 41… the federal government could implement
trough a decree the total or partial reservation of
national water with the objective of ensure the
minimal ecological flow for ecological protection.
– Art. 86 BIS 1, The Commission is allowed
to…“promote water reserves or ecological
reserve according to the law to preserve
wetlands”
6. • Criteria for the identification of water reserves
Water availability and stress (management units)
Biodiversity importance
Water extraction restrictions
Presence of hydraulic infraestructure (big dams)
Agricultural Irrigation Districts
Overexploited aquifers
Population density
7 Core variables
