Water is not only the source of life for human beings but it has also always played a central role in the economic, social and environmental development of countries. With the looming challenge of climate change, governments are increasingly recognising the urgency of ensuring the sustainable management of water resources. Successful water policies can set a strong basis for improving the life of all citizens, and the 2030 Water Agenda provides a solid start to this process in Mexico. There is now an opportunity for the new administration to make Mexico a leading example of successful water reform in OECD and Latin American countries.
