Summary: International initiatives for reducing carbon emissions from deforestation and forest degradation (REDD+) can significantly contribute to tropical countries' national climate commitments. This study evaluates the effectiveness of a partnership between Norway and Indonesia, which implemented a moratorium on new concessions in certain forests. The results show that the moratorium had limited impact on dryland forests but failed to protect carbon-rich peatland forests. Despite its limitations, the moratorium resulted in significant emissions reductions and contributed to Indonesia's climate goals.

Summary: This article analyzes the challenges and scope of implementing REDD+ in the Guaviare region of Colombia, finding that in the post-conflict context, there are many obstacles to successful implementation, including power vacuums, land grabbing, and corruption among regional elites.

Summary: This study found that during the Amazon rainforest fire season, the atmospheric CO2 concentration is about 2 ppm higher than in surrounding areas, mainly due to surface biomass burning, enhanced sinking air over the eastern part of the Amazon, and surface winds.

Summary: One of the main elements in the mechanisms proposed by REDD+ is to pay countries for real reductions in deforestation and GHG emissions, as well as other benefits. To estimate emission reductions, a Reference Level needs to be established using historical average or Business as Usual scenarios. However, the current proposals set the Reference Levels equal to historical deforestation, which differs from the predictions of the Forest Transition theory. Our study shows how incorporating the predictions of the Forest Transition theory and other socio-economic variables into predictive models can accurately estimate future deforestation.

Summary: The southeastern Amazon is a net carbon source due to drying conditions. This study assesses the origins of precipitation in the carbon source region and its relationship with vegetation productivity and land cover. Results show that 13% of the precipitation in the carbon source region has evaporated from the same area, and fully forested areas have higher carbon productivity. The study highlights the importance of maintaining the Amazon forest to sustain carbon and hydrological cycles.

Summary: An Integrated Assessment Model (IAM) and a Narrative Policy Framework (NPF) were used to investigate land use changes in the Brazilian Amazon. The results demonstrate that employing an IAM with a systems approach facilitates stakeholder participation and enables the establishment of effective land use and management policies to address environmental, climate change, and economic sustainability issues.

Summary: Carbon capture, storage, and sequestration play a crucial role in mitigating the adverse effects of climate change. To achieve the 2 degrees C target, it is essential to implement both artificial and natural carbon capturing techniques and utilize renewable resources. This review critically examines various natural carbon pools, methodologies, and modeling techniques for carbon accounting, providing specific recommendations and highlighting the potential benefits of natural carbon sinks. Ground and field measurements are identified as the most accurate methods, while satellite earth observation, drone, and airborne measurements show significant potential for enhancing ecosystem analysis.

Summary: Deforestation and degradation in the Amazon have led to significant losses in biomass carbon, outweighing the gains from regrowing forests. This study provides a pessimistic assessment of the Amazon's carbon balance and highlights the urgent need to address the rising deforestation and degradation, especially in the Brazilian Amazon.

Summary: Leakage is a common issue at all levels of implementation in climate mitigation, particularly concerning REDD+ where reduced deforestation in one area may lead to forest loss in another. Managing leakage requires addressing it locally through avoided deforestation projects, nationally through well-designed policies, and internationally through demand-side standards for forest-risk commodities. Integrating avoided deforestation projects into larger REDD+ programmes can help manage and monitor leakage at various scales.

Summary: Selective logging is widespread in tropical regions, causing depletion of forest biodiversity and carbon stocks. Carbon payments can protect forests from degradation, but their feasibility in the Amazon is uncertain. A study finds that a relatively low carbon price can effectively safeguard large tracts of the Amazon rainforest and provide cost-effective opportunities for protection.

Summary: Forest carbon flux is the difference between carbon loss and CO2 removal due to photosynthesis. The Amazon rainforest contributes a quarter of global emissions from land use change, largely due to its size and carbon storage. Despite deforestation being the main contributor to carbon loss, degradation and natural disturbance also play significant roles.

Summary: In order to limit global temperature rise to 2 degrees Celsius, a large portion of coal, gas, and oil reserves need to be left untouched underground. However, there is a lack of discussion on institutional mechanisms and financial mechanisms for compensating right-holders. An auction mechanism is proposed to determine which fossil fuel reserves should be kept untapped, alongside discussions on funding through taxes. Effective identification of unburnable fossil fuel reserves and accompanying funding mechanisms is crucial for climate negotiations.

Summary: The Galapagos Islands have experienced a temperature increase of 0.6 degrees Celsius since the early 1980s, becoming drier with delayed onset of the wet season. Future climate projections suggest a potential increase in precipitation of 20-70%, along with more extreme wet and hot conditions. Regional sea surface temperatures have risen by 1.2 degrees Celsius over the last two decades, leading to potential deterioration of marine ecosystems.

Summary: Dengue fever is not only a major health issue in large urban tropical areas, but is also observed in rural regions. Studies have shown that the physical landscape and sociodemographic factors can influence vector populations and dengue virus incidence rates. Research findings indicate that rural spatial organization can help explain disease risk, with Afro-Ecuadorian households being more susceptible to symptomatic dengue fever compared to Indigenous Chachi households, a relationship that can be attributed to vegetation proximity and distance to public spaces like football fields.

Summary: This research, conducted in the city of Esmeraldas in Ecuador, aims to create a predictive scenario of urban growth linked to future climate projections. The study finds a positive relationship between urban growth, the proportion of Afro-Ecuadorian people, and the risk of landslides and flooding. The findings suggest that future urban growth in Esmeraldas may increase vulnerability to climate change.
