I have written articles about the importance of water before In our daily life An inexhaustible resource, but has certain requirements for human life And other species.
Follow up on SDG 6 at the international level, Data portal and indicators Focus on the following:
- Water for human drinking.
- Drinking water sanitation.
- waste water.
- Water quality.
- Processing efficiency.
- Lack of water.
- Drinking water management.
- Transboundary waters (river, lake, aquifer, other waters).
- Ecosystems that depend on water bodies.
- International financial flows.
- Multi-stakeholder participation (governance).
How does Mexico comply with the SDG 6 roadmap?
According to the above portal data, we noticed Mexico within a certain range, The average compliance rate is between 40%-60%. In order to provide context for these current results, several factors need to be considered.
- in accordance with Conical, About One third of Mexico’s population Being in poverty due to social deprivation; among them Lack of drinking water, septic tank system and drainage equipment, Such as basic housing services.
- UNICEF and the World Health Organization created a An international portal to monitor the improvement of sanitation facilities by country, Mexico also has its profile, shown in Health conditions improved by 50% from 2000 to 2017.
- according to OECD, 80% of the country’s population can use wastewater treatment; however, in Mexico has no geo-referenced map of wastewater discharge, only one map From Wastewater treatment plant Estimated in 2018 63.8% processed of 215.8m³/s of collected wastewater.
- according to OECD, Their country/region wastes an average of 21% of drinking water; nevertheless, Mexico’s waste (in some cities) is between 40%-60% due to illegal consumption, poor infrastructure quality and measurement errors.
- CONAGUA passed National Water Quality Measurement Network, Monitoring of major water bodies in the country.Divide them into surface water and ground water Selected biochemical and toxicity indicators; In both cases, the result is Only one third of the available drinking water meets quality requirements Areas where drinking water is heavily polluted are located in the middle of the country.
- according to OECD, more than 90% of cities Found that the biggest difficulty in managing drinking water is Public infrastructure: old and dilapidated.
- in accordance with Data from the World Resources Institute (WRI), Mexico in The 24th place on international water stress: The demand for drinking water is higher than the available quantity.
Drinking water management
- according to CONAGUA’s Public Registry of Water Rights (Repda), Activity with The consumption of drinking water is: hydropower (does not affect water consumption), agricultural water and Provide housing and local public services.
Transboundary waters (river, lake, aquifer, other waters)
- in accordance with player, Mexico has 18 transboundary aquifer systems: 11 on the northern border and 6 on the southern border.
- In the case of the southern border, the Yucatan peninsula’s aquifer is regarded as the country’s most important freshwater storage area, but the area is poorly managed. Enerall Corporation, Reported by Greenpeace Before the federal administration because of a conflict of interest.
Ecosystems that depend on water bodies
International financing flows
- The Colorado and Bravo rivers receive the most attention If it is the northern border area, the project involves the initiative of the US government,Xinhe Project“Until you get The Rio Bravo Adaptation Project of the Global Environment Facility implemented by the Organization of American States.
- Financial products such as Sustainable bonds issued by RotoplasIn addition to solving environmental and social challenges, the purpose of the plan is to provide financing or refinancing for projects to improve water supply and sanitation, and is an innovative mechanism to attract international private capital.
Multi-stakeholder participation (governance)
- according to OECD, This Diversity of all parties involved in the design and implementation of public policies Issues related to water management can present governance challenges in the following situations Coordination mechanism There is no clear description.
- The most common problem is Except for power overlaps or legal loopholes, there is a lack of horizontal strategic vision, power asymmetry among government authorities, and a lack of consistency in national and local legislation. in this aspect, Water Advisory Committee. A brief assessment of Mexico was made.
In short, The contextualization of drinking water management in Mexico requires a multidisciplinary perspective, in which many factors need to be analyzed from a complex system framework. The achievement of SDG 6 by 2030 requires that the annual goal be achieved through a monitoring system that can generate data visualization for use by the general public.
