Recently, the Conservancy has been working with Monterrey’s FEMSA Foundation as well as the International Inter-American Development Bank and the Global Environmental Facility (GEF) on creating a water fund for the city, with the support of many other local stakeholders. High above the city, the Conservancy is helping local landowners plant tens of thousands of trees and improve management of natural areas to help secure drinking water supply at its source. This conservation work has also been designed to slow water and reduce sediments to minimize the impacts of heavy rains, protecting local communities when hurricanes occur. This important step has convinced many local leaders of the power of nature and conservation.
This water funds work has positioned our science and global expertise as a key source of credibility. Working with many of the same institutions and leaders, we are now ready to tackle the challenges of flood management and water recharge in strategic areas of the city. The Water Center for Latin America and the Caribbean at the Monterrey Institute of Technology and Higher Education has already begun mapping existing city parks, calculating their flood management potential, and projecting what green connections and additional natural infrastructure would be needed to create effective stormwater barriers.
The Gran Rio la Silla Park was conceived as a major attenuation tank for floodwaters, as the La Silla River swells during periods of heavy rain. The park hosts 350,000 visitors every year and, in case of heavy rains, protects the surrounding neighborhoods from flooding.
Even the city’s new C.F. Monterrey football stadium, located within the park, is playing a part: The parking lot is designed to absorb rainwater runoff with swales (natural areas where plants and soil absorb rain) and permeable pavements. And the stadium’s grounds are designed as public space that offers opportunities for families to play sports and interact with nature.
The Nature Conservancy’s green infrastructure work will also include water recharge areas in our mapping—specifically how we can not only stop floods but also provide more opportunities to use natural areas to capture water and recharge aquifers.
Cleaner, Healthier Air
And we will study the potential for nature to help clean up local air pollution that has grown as part of the ongoing construction boom. Global studies at the neighborhood scale have shown that trees and vegetation can remove 20-50% of fine particulate matter pollution, which comes from dust, car exhaust and factory emissions. As cities around the world have taken measures to clean up polluted air, the pollution in industrialized cities like Monterrey has grown worse. For neighborhoods near freeways or industrial centers, using trees to help address pollution can have positive outcomes on health, well-being and productivity.
Monterrey is among more than 250 cities that will be included in a global Planting Healthier Air Index this fall, which will help city planners understand “what kind, where and how much” nature can help with air pollution.
I can’t wait to return to Monterrey to see how nature can serve this rapidly transforming city. It’s a dynamic place, where change and growth have become a way of life, and the people I met during my visit are excited to bring the power of nature to Nuevo Leon.
