Road construction inside the Sian Ka'an Biosphere Reserve continues despite a government statement to minimize development.

The ongoing road projects threaten mangroves, cenote sinkholes, and dunes within this protected area. Environmental groups argue that such activities could lead to irreversible ecological damage, impacting biodiversity and local ecosystems crucial for climate resilience.

Local communities fear the construction will harm their livelihoods dependent on tourism and fishing, which rely heavily on preserving the natural beauty of the reserve.

The long-term vulnerability includes degradation of critical habitats, increased erosion, and loss of carbon sinks that protect against rising sea levels.

What is the long-term climate outlook for this region?

Continued road construction could exacerbate coastal erosion and reduce natural buffers against storms. This threatens not only biodiversity but also the resilience of local communities to climate impacts.

The outlook remains negative due to ongoing development pressures.
