Municipalities and local communities across Latin America and parts of Southeast Asia continue to implement sanitation, waste management, and environmental maintenance initiatives, transitioning from basic upkeep to sophisticated climate risk mitigation. In Argentina, efforts include remediating open-air landfills in Jujuy via the GIRSU Project and managing flood risks through drainage works in Paraná and Reconquista. New legislative and administrative measures have emerged, such as a proposed law for an integrated water basin monitoring system and the formation of a Municipal Risk Management Committee in Santa Fe following a water emergency. Local actions also include cleaning campaigns in river areas and updating hydrological risk maps in Chascomús. Circular economy and waste management strategies are expanding. In Mexico, Querétaro continues organic waste composting, while Morelos’s tire transformation project has recovered over 90,000 tires to produce alternative fuel. In Chile, Mejillones has delivered used tires for recycling to prevent fires and pest accumulation. Additionally, Mexico’s Ministry of Environment is advancing a National Restoration Program to recover rivers and mangroves. Urban maintenance and infrastructure improvements are also widespread. In Chile, Alto Hospicio and Arica have invested in vehicle fleets for cleaning and green space upkeep. In Bolivia, the La Paz Mayor’s Office has deployed machinery to manage waste following contractor service interruptions. In Venezuela, authorities are working to restore the Laguna de Urao through sediment removal and invasive vegetation extraction.
