• Climate Change

In the Mexican state of Jalisco, a member of Regions4, flows an important river called Santiago. Originating from Lake Chapala, it winds around Guadalajara and empties into the Pacific Ocean. Despite its importance, decades of severe pollution have made it one of the most contaminated rivers in Mexico.

Stretching over 400 kilometers, the river has long been central to the region’s history, economy, and the livelihoods of its surrounding communities. However, environmental degradation in the Santiago River Basin has deeply impacted natural heritage and quality of life for its inhabitants.

In late 2018, hope emerged through the “Comprehensive Strategy for the Recovery of the Santiago River,” known as “Revivamos el Río Santiago” (Let’s Revive the Santiago River). This initiative, led by the Jalisco government, focuses on both ecological restoration and improving conditions for nearby communities.

The strategy is built around six key components: governance, healthy communities, natural heritage, rule of law, development resources, and infrastructure and services, all tied to the protection of human rights, particularly Economic, Social, Cultural, and Environmental Rights (ESCER).

At the heart of the initiative lies the principle that the health of the river is inseparable from the health of its inhabitants. It is not merely an environmental rescue plan but a holistic approach to addressing the social needs of citizens affected by the pollution of this vital water resource.

From Words to Actions on the Ground

The Revivamos el Río Santiago strategy is a tangible commitment backed by concrete actions. It focuses on a Priority Intervention Area comprising 18 municipalities where the most urgent problems are concentrated, enabling efforts to be targeted through a basin-focused approach.

Nonetheless, its reach extends throughout the entire territory of Jalisco, just as the river itself does.

Over the years, the strategy has evolved through improved governance, leading to innovative programs, infrastructure projects, and technological advances that have reshaped the narrative surrounding the Santiago River.

Domestic water treatment coverage in the Santiago, Verde, and Zula river basins has risen from 61% in 2018 to 75% in 2024, with projections reaching 98% upon completing current technical projects.

The path to full recovery remains long, but the Government of Jalisco is steadfast in its commitment to the future. Revivamos el Río Santiago is not only a vision for the 2018–2024 period but also for generations to come.

Each step in the Revivamos el Río Santiago journey highlights the essential role of subnational governments in driving change. With their dedication, determination, and regional knowledge, they can revive not only a river but also the vital connection between people and nature, contributing to a more sustainable, biodiverse, and climate-resilient world.
