The AC-CReWS project aims to enhance climate resilience on Ambergris Caye, Belize, by upgrading water and wastewater infrastructure and governance. The project focuses on transitioning to low-carbon systems through the installation of a 3 MW grid-tied PV system, upgrading sewage treatment to tertiary levels for reclaimed water reuse, and implementing SCADA for automated monitoring and leak detection. With a total indicative cost of USD 49.893 million, the project targets 40,000 direct beneficiaries and expects to mitigate 148,140 tCO2eq over a 30-year lifespan. It also proposes a Revolving Adaptation and Mitigation Fund Facility (RAMFF) to sustain small-scale climate initiatives.

The study identifies a positive association between dengue fever occurrence in the Belize District and both precipitation and minimum temperature. Projections for the 2050s suggest a general warming trend with an increase in the frequency of days where minimum temperatures exceed 18°C, which may increase DF occurrence. Conversely, a projected increase in days where maximum temperatures exceed 32°C may create less favourable conditions for the disease. The report emphasizes that non-climate factors, including changes in health reporting structures and socio-economic drivers, also influence DF trends.

The report identifies high-risk hotspots in Belize's coastal tourism sector, particularly Ambergris Caye, Caye Caulker, and the Central and South Central regions, which face significant threats from sea-level rise, thermal stress on coral reefs, and hurricane intensity. It highlights that 86% of tourism facilities are highly vulnerable to sea-level rise, with potential GDP losses of over US $61 million from a 1m rise. While some regions like the Northern and Southern areas show medium vulnerability, the overall outlook suggests a high potential impact on the industry's future viability.
