Brazil is expanding its focus on urban climate resilience and disaster management. The Ministry of Cities updated its primary urban risk management manual, ‘Mapeamento de Riscos: Conceitos e Métodos Aplicados a Processos Geológicos e Hidrológicos’, for the first time since 2007. This update, driven by climate urgency and El Niño, introduces a streamlined classification system for medium, high, and very high risk levels to help municipalities map vulnerabilities and access prevention resources. In the Amazon region, climate strategies are shifting from a primary focus on deforestation to include urban resilience. Through the ‘Brazil Mutirão’ program—a collaboration between C40 Cities and the Global Covenant of Mayors for Climate & Energy—11 Amazonian cities are receiving support for infrastructure, waste management, and sustainable mobility. Additionally, 50 municipalities are utilizing the ‘City Climate Compass,’ an AI-powered platform designed to synthesize climate data and emission profiles for evidence-based policy planning. Efforts in the Amazon are increasingly intersecting environmental preservation with a sustainable bioeconomy. Initiatives such as agroforestry and indigenous agriculture are transforming biodiversity into commercial products. As Amazon Day (September 5) approaches, the ‘Amazônia de Pé’ movement is mobilizing voters ahead of the October 4 elections, urging citizens to support candidates committed to forest conservation. While 2025 data indicated a decrease in deforestation rates to 5,731 km², the region remains under pressure from illegal mining and land grabbing. Climate change is intensifying through phenomena like El Niño, which has caused record heat in Acre and severe droughts affecting river navigation and food security. Indigenous leaders and women are demanding greater political protagonism and the legal recognition of nature as a subject of rights to combat high rates of violence against environmental defenders.
