Land use still matters after deforestation.

Careful management of deforested Amazonian land cannot replace, but must complement, efforts to preserve the rainforest. Sustainable agricultural practices that promote diverse uses can help minimize climate and environmental impacts....

Out of steady state: Tracking canopy gap dynamics across Brazilian Amazon.

Canopy gaps are evidence of disturbances on forest landscapes. A forest stand is in constant flux, with long stretches of biomass accumulation punctuated by episodic disturbances. We used multitemporal airborne laser scanning data to compare the gap dynamics of four Amazon forest sites. We assessed ...

Evaluating carbon and water fluxes and stocks in Brazil under changing climate and refined regional scenarios for changes in land use.

Climate change and land-use change can alter the role of natural vegetation as a sink or source of atmospheric carbon. In this work, we evaluate the response of water and carbon fluxes and stocks in Brazilian biomes as a proxy for ecosystem services of regional climate regulation under two contrasti...

Sea-air CO2 fluxes along the Brazilian continental margin.

Measurements of the marine carbonate system on tropical and subtropical continental margins are poorly distributed in space and time, with many uncertainties persisting regarding the role of carbon exchanges at the ocean-atmosphere interface in these areas. To calculate sea-to-air CO2 fluxes in Mari...

Spatial inequalities in access to safe drinking water in an upper-middle-income country: a multi-scale analysis of Brazil.

Access to drinking water is recognized as a human right, meaning that it is necessary to guarantee its universal and equitable access. Since analyzing only the average access rates to drinking water may obscure inequalities, studies have adapted socioeconomic inequalities indices to assess dispariti...

Dinâmica da paisagem e fragmentação de ecossistemas em três bacias hidrográficas na Amazônia Oriental entre 1985 e 2019.

O Nordeste Paraense sofreu profundas mudanças no decorrer dos seus ciclos de ocupação. Nessa região, a conversão de floresta para outras classes de uso e cobertura da terra ocorre há centenas de anos. Com o advento do Sensoriamento Remoto, é possível quantificar essas mudanças. Nesse senti...

Participatory pathways to the Sustainable Development Goals: inviting divergent perspectives through a cross-scale systems approach.

The United Nations Sustainable Development Goals (SDGs) include social and ecological goals for humanity. Navigating towards reaching the goals requires the systematic inclusion of perspectives from a diversity of voices. Yet, the development of global sustainability pathways often lacks perspective...

Impacts of climate change on the potential distribution of epiphytic cacti in the Caatinga biome, Brazil.

The Caatinga biome is the largest dry tropical forest region in South America as well as one of the most vulnerable regions in the world to the climate changes forecast for this century. Climate forecasts for the biome include increased air temperature, reduced rainfall and aridization. This biome d...

Impact of land tenure on deforestation control and forest restoration in Brazilian Amazonia.

This study examines how land tenure constrains Brazils ability to meet its deforestation control and forest restoration goals in its Amazonia biome. Our findings are based on an updated assessment of land tenure and land use in the region. Between 2019 and 2021, 44% of deforestation in Amazonia occu...

Comparação entre os modelos digitais de terreno gerados por radar em banda P e LiDAR na Amazônia, um estudo de caso no Amapá (Brasil).

The Digital Terrain Model (DTM) is an important product used in geosciences, but its extraction in dense forest areas is still a challenge. One of the major difficulties in extracting a DTM via remote sensors is in dense forest areas, as the generated information becomes degraded due to the fact tha...
