The climate change opportunity
There is common understanding that we are facing a serious set of problems
Water is a key issue in economical and human development and conservation (Food, Water and Energy Security)
The water and conservation science communities hold a wealth of tools, data products and solutions
There is an opportunity to demonstrate a conservation based approach to development

Climate change vulnerabilities:
– Extreme events: physical capacity to mange /attend risk foods
– Variability in water availability: with main focus in droughts
• Overallocation

Water reserves: – Reduce user water risk– Prevents overallocation– Reduce water resource vulnerability– Secure/increase adaptive capacity of both people and nature

THE MEXICAN PUBLIC POLICY CASE• Water Reserves are considered in National Water Law• It came out the need for a National Standard to
estimate that water reserve. o It was developed based on mexican and international
experience, with the participation of the academy, government agencies, and NGO.
o It recognizes: – A needed balance between water use and ecologicalimportance
– Surface and groundwater integration– Preventive principle for sensible ecosystems– Climate variability

1. Built on national water law which recognizes the environment water‐needs
2. Turns a limiting regulation into a securing regulation
3. Safeguards ecosystem resilience
