Nature-based solutions (NbS) are being integrated into climate strategies across Latin America and the Caribbean to address biodiversity loss and climate change. While they offer significant economic and ecological potential—such as protecting coastal resilience and sequestering carbon—they cannot replace the need for deep emissions reductions from fossil fuels. The document warns that vague definitions of NbS can lead to 'greenwashing' by polluting corporations and risk the displacement of Indigenous and local communities through land grabs and monoculture plantations. For NbS to be sustainable, the author argues they must be based on local knowledge, ensure Free, Prior, and Informed Consent (FPIC), and be supported by diverse financing mechanisms beyond voluntary safeguards.

The project examines hydroclimate variability in the American cordillera, specifically in western Canada, Mexico, the Altiplano, and Southern South America. Using tree-ring data, glacier studies, and streamflow records, the research analyzes the relationships between precipitation, runoff, and climatic drivers like ENSO and PDO over the last 300 years. Key outputs include long-term drought and precipitation reconstructions for central Mexico and the Bolivian Altiplano, as well as snowpack and river reconstructions for the Southern Andes.

The document reports that tropical dry forests in the Americas are highly endangered, with only 40% of their original extent remaining and only 4.5% protected. Satellite data from 1982 to 2006 shows divergent productivity trends: forests in the Brazilian Caatinga and parts of Mexico are losing productivity, while those in the Llanos of Venezuela and Colombia, Northern Mexico, and the Chaco of Argentina and Bolivia are seeing increases. These shifts are linked to global warming's effect on rainfall and moisture. The text warns that productivity losses threaten carbon storage and water resources, while productivity gains may encourage further deforestation and agricultural intensification. It advocates for expanded protection beyond national parks, including economic incentives and sustainable land management.

The document reports that as of September 30, 2024, the Inter-American Institute for Global Change Research had received 38% of its member contributions for the 2024-2025 fiscal year. Total accumulated expenditures for the first three months of the fiscal year were $375,107, which is 10.7% lower than the budgeted amount of $420,000. Reductions in spending were most notable in operating costs (-22.7%) and travel and training (-10.9%).

The briefing examines the expansion of LNG infrastructure in Latin America and the Caribbean, highlighting significant planned investments in Mexico, Argentina, and Brazil. It argues that these projects risk becoming stranded assets and conflict with global climate goals to limit warming to 1.5°C, suggesting that the region should instead prioritize its abundant renewable energy resources.

Since 2023, Chinese firms have committed over US$100 billion in outbound foreign direct investment (OFDI) across at least 130 major cleantech transactions, spanning solar, wind, batteries, and new energy vehicles (NEVs). This 'going global' strategy is driven by domestic overcapacity, which has caused solar module prices to drop 60% and battery prices 50% year-on-year, and a need to circumvent trade barriers from the US and EU. The report highlights China's dominance in the global battery supply chain, where it holds over 80% of manufacturing capacity, and its expansion into markets like Morocco, Brazil, and Thailand. For Australia, the report notes that Chinese OFDI reached a multi-decade low of US$613 million in 2023, and argues that Australia should clarify its foreign investment rules to attract Chinese private capital for onshore value-adding in critical minerals and renewable energy infrastructure.

The report analyzes the hydrological impacts of forest fires and deforestation in the Chiquitania region of Bolivia, specifically focusing on the Curichi Grande and Tucavaca watersheds. It details the development of a multi-criteria prioritization tool using Google Earth Engine (GEE) and a hydrological model using WEAP to assess water availability and soil retention. Field findings from 2021-2022 highlight critical water scarcity and quality issues in local communities following the 2019 and 2020 fires, while the report argues that integrating fire risk into water management is essential for sustainable regional development.

The IAI Executive Directorate is implementing CoP-32 mandates by strengthening scientific communication, developing digital monitoring systems for its Strategic Plan, and establishing partnerships with institutions like CR2, FAPESC, and STRI. Key initiatives include the 'Tropical Forests' Collaborative Research Action (CRA), the 'Climate, Environment and Health' (CEH) program, and the creation of the Center for Science Diplomacy. The Directorate is also advancing gender, equity, diversity, and inclusion (GEDI) policies and establishing advisory committees for indigenous peoples and local communities.

The BEST-P project investigates the relationship between land cover dynamics and ecosystem services in southern South America, specifically focusing on carbon and water regulation. Using remote sensing and field studies, the project has quantified the impacts of deforestation and afforestation in the Chaco region, analyzed the influence of different landholder types on conservation, and developed tools to integrate biophysical and human dimensions into territorial planning. The initiative also provides evidence to support legal actions against illegal deforestation in Argentina by demonstrating cross-province climatic impacts.

The project establishes a Nitrogen, Society, and Environment Network (Nnet) to study the impacts of human activity on the nitrogen cycle across various Latin American ecosystems. It integrates empirical measurements of biological nitrogen fixation, atmospheric deposition, and fertilizer use with regional modeling to inform policy and environmental management.

The project aims to create a regional understanding of the nitrogen cycle in Latin America by measuring biological nitrogen fixation, atmospheric deposition, and the impacts of land-use changes. Initial findings include high nitrogen pollution in Venezuelan rivers, low biological nitrogen fixation in Chilean forests affected by copper mining, and the influence of urban and industrial areas on NOx concentrations in São Paulo. The initiative seeks to provide guidelines for policymakers to manage nitrogen and minimize environmental degradation.

The report assesses climate vulnerability and institutional adaptive capacity in the Mendoza, Choquecota, and Elqui river basins. It finds that current adaptive capacities of producers and governments are insufficient to meet future climate challenges, citing poor institutional coordination and lack of integrated water management. While commercial farmers in Argentina and Chile have some protection due to capital and institutional frameworks, poor populations and traditional farmers in Bolivia remain highly vulnerable, relying on local resources and traditional knowledge. The study highlights a critical lack of early warning systems across all basins and suggests that policies targeting resource concentration and risk prevention could reduce vulnerability.

The project examines how changes in land cover—such as the transition from forests to agriculture and grasslands to tree plantations—affect the hydroclimate of the La Plata Basin. Using data from 1980 to 2005 and the Weather Research and Forecasting (WRF) modeling system, the research assesses changes in soil moisture, infiltration, runoff, and the intensity and duration of droughts and floods. A key methodological innovation is the use of Ecosystem Functional Types (EFTs) to replace static land cover types in regional models.

The document analyzes the vulnerability of agricultural communities in three Andean river basins (Mendoza, Argentina; Choquecota, Bolivia; and Elqui, Chile) to climate variability. It finds that adaptation capacity is critically limited by poor institutional coordination, lack of water data, and absence of early warning systems. While stronger state frameworks in Argentina and Chile benefit large commercial producers, poor populations remain highly vulnerable. In Bolivia, the lack of state presence makes traditional farmers particularly susceptible, relying primarily on traditional knowledge for adaptation.

The document examines the relationship between soil microorganisms and plants, focusing on arbuscular mycorrhizal fungi (AMF). It argues that land-use and climate changes affect these microorganisms, which in turn impacts plant nutrition and agricultural yields. Findings indicate that AMF diversity and symbiotic capacity can decline during warm and dry seasons, potentially leading to a loss of the symbiotic relationship. In the páramos region, this research has been applied to create biofertilizers that increase potato growth in Bolivia and Ecuador.

The MAP-Fire project investigates the increasing risk of wildfires in the Amazon, particularly in the transborder region of Madre de Dios (Peru), Acre (Brazil), and Pando (Bolivia). It aims to quantify fire impacts, identify bottlenecks in monitoring strategies, increase population risk awareness, and influence conservation policies to support Sustainable Development Goals and the Sendai Framework for Disaster Risk Reduction. Findings indicate that 2019 fires in Acre burned 1,802 km2—an 80% increase over 2018—leading to 21 days where air pollution exceeded WHO limits. The project also highlights that standard wildfire contingency plans are ineffective during extreme droughts, which increase forest vulnerability and affected areas.

The MAP-Fire project (2019–2022) focused on the 'MAP' region (Madre de Dios in Peru, Acre in Brazil, and Pando in Bolivia) to address the increasing risk of forest fires driven by climate change and land-use changes. Key achievements include the development of a real-time fire monitoring platform, the quantification of significant economic losses in Acre, Brazil, and the identification of air quality crises linked to fire events. The project also integrated fire risk education into public schools and provided technical reports to governments to support National Determined Contributions (NDCs) and the Sendai Framework for Disaster Risk Reduction.

The document examines debt-for-nature swaps, where foreign currency debt is cancelled in exchange for local currency investment in environmental projects. While popular in Latin America and the Caribbean, the tool is described as having a very small market impact, offsetting only 0.11% of debt payments for low- and middle-income countries between 1987 and 2023. The IMF suggests that conditional grants or comprehensive debt restructuring are often more effective depending on debt sustainability. Case studies from Bolivia, Costa Rica, and Ecuador highlight risks including loss of national sovereignty, negative real interest rates, and the exclusion of Indigenous communities.

Between August 22 and 25, 2024, over 60 million people in Brazil faced extreme temperatures and wildfires exacerbated by climate change. High temperatures were forecasted to be five times more likely due to global warming, with anomalies reaching up to 10°C above normal in São Paulo. Wildfires have burned over 760,000 hectares in the Amazon and 1.3 million hectares in the Pantanal, with climate change increasing Pantanal fire intensity by 40%. On August 20, PM2.5 pollution levels reached 11 times the World Health Organization's recommendations, causing increased respiratory illnesses and affecting 10 Brazilian states as well as Bolivia, Paraguay, and Peru.

The report assesses gender inequalities and diversity challenges in the Amazon Basin, highlighting disparities in land tenure, political representation, and access to water and sanitation. It emphasizes the critical role of indigenous women in biodiversity conservation and the disproportionate impact of climate change on vulnerable populations.
