How climate change and deforestation interact in the transformation of the Amazon rainforest

Nature Communications
The Amazon rainforest is one of Earth’s most diverse ecosystems, playing a key role in maintaining regional and global climate stability. However, recent changes in land use, vegetation, and the climate have disrupted biosphere-atmosphere interactions ...

Expansion of the Brazilian Sugarcane Bioenergy System Promotes Greenhouse Emission Reductions and Sustainable Development Without Compromising Food Security

Sustainable Development, EarlyView.
ABSTRACT The growing global demand for biofuels has raised concern about compromising food security. This study uses two independent economy‐wide models to evaluate the impact of expanding the Brazilian sugarcane bioenergy system on economic growth, social outcomes and food security.

Discriminating Land Use and Land Cover Classes in Brazil Based on the Annual PROBA-V 100 m Time Series

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Brazil, with more than 8 million km2, presents six different biomes, ranging from natural grasslands (Pampa biome) to tropical rainfall forests (Amazônia biome), with different land-use types (mostly pasturelands and croplands) and pressures ...

Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

Wildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

Journal of Animal Ecology, EarlyView.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

The Economic and Ecological Impact of Soy in Brazil: A Synthetic Control Method Approach

Journal of Agricultural Economics, EarlyView.
ABSTRACT In recent decades, soy expansion in Brazil has generated significant environmental, social and economic impacts. However, there is no consensus about benefits and drawbacks, calling for a more careful account of the economic and ecological diversity of the territories where this phenomenon has been unfolding.

The MapBiomas Uruguay initiative to monitor annual land use and land cover changes from 1985 to 2023

Ecología Austral
1. Land use and land cover change has been identified as one of the most significant drivers of the Earth system. In this context, the production of accurate, detailed and long-term maps is essential.2. Here, we present Collection 2 of MapBiomas Uruguay, which provides annual land use and land cover maps for the country spanning the period from 1985 to

Aligning Transnational due Diligence: The EU Deforestation Regulation and Brazil's Fragmented Beef Governance

Global Policy, EarlyView.
ABSTRACT Transnational due diligence regulations, such as the European Union Regulation on Deforestation‐Free Products (EUDR), are reshaping sustainability governance by transforming voluntary norms into binding global rules. Yet, their effectiveness depends on how well they align with domestic governance systems and on the power asymmetries that ...
