Brazil’s Urban Nature Strategy Treats Maintenance as National Policy

Brazil has opened consultation on a national strategy for nature-based solutions in urban and peri-urban areas. The draft sets 12 national guidelines and a 2026–2035 action plan, with the ambition of registering and implementing nature-based solutions in 17.5 per cent of Brazilian municipalities by 2035.

The target is visible, but the structure beneath it is more consequential. The action plan is divided into six axes: institutionalisation and regulatory integration; communication and capacity; socio-environmental justice and participation; finance and scaling; maintenance and adaptive governance; and data, information and research. That list treats urban nature as a public-delivery system rather than an inventory of parks, rain gardens or restored waterways.

This is a necessary shift. Nature-based projects often enter policy through a capital program: a wetland is restored, a slope planted or a drainage corridor greened. The benefits then depend on responsibilities that are less photogenic. Someone must protect the land, manage sediment and invasive species, inspect drainage, replace vegetation, keep data current and adapt the intervention as rainfall, heat and land use change.

By naming maintenance and adaptive governance as a national axis, the draft puts those continuing duties inside the strategy rather than leaving them to project aftercare. The distinction matters because a nature-based asset is not static. Its performance develops over time and can improve or deteriorate with ecological condition, surrounding development and municipal capacity.

The governance model is correspondingly broad. It involves the federal government, states, the Federal District, municipalities, civil society, the private sector and academia. The strategy was developed through workshops in all five regions, virtual consultations and institutional meetings. The regional activities involved 442 participants, including public authorities, researchers, businesses, civil-society organizations, traditional peoples and communities, and state and municipal managers.

Participation does not guarantee implementability, but it helps expose the differences a national strategy must accommodate. A coastal metropolis managing heat and stormwater does not face the same operating conditions as an inland municipality dealing with drought, erosion or landslide risk. A common national framework therefore needs enough definition to guide finance and measurement without forcing unlike places into one project template.

The justice axis is equally practical. Brazil’s Periferia sem Risco program already connects slope stabilisation, macro- and micro-drainage, risk mapping, community plans and nature-based solutions in vulnerable urban areas. The draft strategy can strengthen that work if it directs resources toward exposure and service gaps rather than counting projects wherever delivery is easiest. A municipal percentage alone cannot show who is protected, which hazards are reduced or whether the benefits reach informal and underserved neighborhoods.

Finance and regulatory integration will determine whether the strategy moves beyond pilots. Nature-based measures compete with familiar grey infrastructure that fits established budgets, engineering specifications and procurement categories. Integrated rules can make green and hybrid options visible in land-use, drainage, water, biodiversity and climate decisions. Finance needs to cover design, land, community engagement, monitoring and upkeep—not merely construction.

The data axis can provide the discipline. Registration is useful if it records location, intervention type, responsible institution, condition, cost and intended service. It becomes more valuable when performance is measured against the local problem: reduced runoff, lower heat exposure, stabilised slopes, restored habitat, improved water quality or safer public space. Counting a project without recording condition and outcome would turn the 17.5 per cent target into an administrative milestone rather than a resilience measure.

The strategy remains a proposal under consultation. Its governance arrangements, targets and actions are not yet proof of adoption, funding or municipal delivery. The ten-day consultation period is also short relative to the range of institutions expected to implement it. Final policy will need to show how responsibilities, finance and national data connect to local plans.

Brazil’s strongest idea is that scaling urban nature requires more than replication. A project becomes durable infrastructure when it has an owner, an operating routine, a maintenance budget, performance information and a way to adjust. The draft has placed those functions in the same national frame. Its success will depend on whether the final strategy gives municipalities the capacity and money to keep them together.
