The document outlines twelve projects (SG-CEH-01 to SG-CEH-12) focused on the climate-environment-health nexus. Key research areas include the expansion of dengue and diarrheal diseases in Peru, Argentina, Colombia, and Cuba; the impact of extreme heat on older adults and urban populations in Mexico City, Buenos Aires, and Chile; and the effects of climate change on nutrition and agroecology in Bolivia and Uruguay. The projects emphasize the need for intersectoral coordination, community participation, and the integration of climate data into public health surveillance and urban planning to build resilience against climate-driven health risks.

• In Peru, the climate crisis is intensifying the prevalence of dengue and diarrheal diseases, particularly in Amazonian territories with structural deficits in water, sanitation, and health services. Vulnerability is multidimensional, involving social, environmental, and institutional factors, with pregnant women, children, and older adults being the most affected.
• Research in Argentina and Guatemala reveals a 'capacity paradox' where regions with higher technical training may still experience high dengue incidence if the public health response remains fragmented. Effective institutional capacity requires the coordination of technical expertise, networks, and local context rather than isolated technical capabilities.
• In Chile, satellite data and spectral indices (NDWI, AWEI) show potential for identifying high-risk areas for waterborne infectious diseases like salmonellosis, though prolonged droughts and gaps in microbiological data hinder the immediate use of operational models.
• Extreme heat in Mexico City is causing symptoms such as dehydration, fatigue, and dizziness, but these impacts are underreported in official health statistics. There are significant territorial inequalities in access to green spaces, with Iztapalapa having a considerably lower index of green spaces per inhabitant than Benito Juárez.
• Cuba's SAT-DENCLIM project developed a bioclimatic early warning system that can predict dengue transmission peaks approximately one month in advance, contributing to a reduction of up to 60% in infestation rates and dengue cases.
• In Micaya, Bolivia, climate-driven frosts and droughts have led to severe nutritional deficiencies, with over 80% of the population lacking vitamin B12 and 40% lacking folate. Additionally, about one-third of participants showed evidence of genotoxic damage, primarily among those exposed to pesticides.
• In Buenos Aires, older adults in vulnerable neighborhoods are disproportionately affected by heat waves and report a greater need for assistance with water and food, though a gap exists where many aware of preventive measures do not implement them, such as insufficient hydration.
• In Jamaica, Airbnb properties are concentrated in areas highly vulnerable to climate risks, including hurricanes and flooding, often lacking adequate access to emergency services or minimum safety and resilience standards.
• In Quilpué, Chile, a correlation was identified between high temperatures and an increase in hospital visits, with residents perceiving a deterioration in thermal conditions in modern housing compared to traditional construction.
• Argentina's climate, environment, and health data are fragmented with moderate compliance with FAIR principles, particularly regarding interoperability and reuse, which hinders evidence-based decision-making.
