Climate Finance as a Pillar for Strengthening Climate Adaptation in Brazilian Cities
By Sândrya Neves (CFC-GS/UFPA) The climate emergency has pushed the world into new scenarios in which the economy, the market, and especially agriculture need to adapt to unprecedented rates of change. In this context, cities also become central and immediate elements of change, since they concentrate populations and infrastructure essential to ensuring minimum conditions of safety and well-being, especially those that are most vulnerable due to their characteristics, such as coastal municipalities that require rapid responses and climate financing directed toward adaptation and resilience. The goal is clear: to reduce the increasingly intense impacts of the climate crisis, whose manifestations range from sea level rise, extreme heat waves, recurrent flooding, intense storms, and prolonged periods of drought. In Brazil, this reality takes on even more worrying contours. Most municipalities already face historical structural difficulties, including a lack of adequate basic sanitation, insufficient drainage, irregular occupations, and a lack of effective urban planning. These deficits not only accentuate the vulnerability of the population, but also highlight deep social inequalities and a pattern of urbanization marked by disorder. Lower-lying areas in urban centers, often prone to flooding, are occupied by marginalized groups, while peripheral regions far from the urban center encroach on remaining forests, putting even more pressure on the environment and amplifying cumulative impacts. In this scenario, cities become the most immediate spaces for transformation, and it is precisely in them that climate finance proves not only necessary but also structural. Furthermore, these dynamics reveal how the climate emergency also reinforces structures of socio-environmental injustice, including expressions of environmental racism. Black, peripheral, and low-income populations are disproportionately affected by extreme events, while having fewer resources to adapt. Given this, it is urgent to ask: do the urban works and policies implemented today in Brazilian cities take into account the environmental scenarios predicted for the coming decades? The answer, although uncomfortable, is often no. Although there have been some advances, we still lack a solid and integrated set of public actions that prioritize climate adaptation, urban resilience, and the reduction of socio-environmental inequalities. The transition to cities prepared for the future involves everything from strengthening green infrastructure, such as parks, ecological corridors, reforestation, and nature-based solutions, to robust investments in urban drainage, decent housing, intelligent water resource management, and the expansion of sanitation in all its dimensions. For all this to be possible, climate finance emerges as a fundamental tool. It represents not only a source of resources, but also a strategic mechanism for enabling public policies, driving innovation, and stimulating sustainable practices. Therefore, addressing the climate crisis through adaptation actions requires planning, science, social participation, and, above all, financial resources capable of transforming diagnosis into action.
