Empowering communities? local stakeholders’ participation in the clean development mechanism in Latin America.
Under the United Nations Framework Convention on Climate Change, the Clean Development Mechanism (CDM) requires local stakeholders to participate by sharing their comments on CDM activities. This stipulation aims at promoting social equity, a key element of sustainable development. We draw on the st...

Using the U-net convolutional network to map forest types and disturbance in the Atlantic rainforest with very high resolution images.
Mapping forest types and tree species at regional scales to provide information for ecologists and forest managers is a new challenge for the remote sensing community. Here, we assess the potential of a U-net convolutional network, a recent deep learning algorithm, to identify and segment (1) natura...

Representation of fire, land-use change and vegetation dynamics in JULES.
Disturbance of vegetation is a critical component of land cover, but is generally poorly constrained in land surface and carbon cycle models. In particular, land-use change and fire can be treated as large-scale disturbances without full representation of their underlying complexities and interactio...

Combined exposure to hydroelectric expansion, climate change and forest loss jeopardies amphibians in the Brazilian Amazon.
Aim: Human-driven impacts constantly threat amphibians, even in largely protected regions such as the Amazon. The Brazilian Amazon is home to a great diversity of amphibians, several of them currently threatened with extinction. We investigated how climate change, deforestation and establishment of ...

Impact of intensive fish farming on methane emission in a tropical hydropower reservoir.
Fisheries and aquaculture are important sources of food for hundreds of millions of people around the world. World fish production is projected to increase by 15% in the next 10 years, reaching around 200 million tonnes per year. The main driver of this increase will be based on fish farming managem...

Biomass burning emission disturbances of isoprene oxidation in a tropical forest.
We present a characterization of the chemical composition of the atmosphere of the Brazilian Amazon rainforest based on trace gas measurements carried out during the South AMerican Biomass Burning Analysis (SAMBBA) airborne experiment in September 2012. We analyzed the observations of primary biomas...

Climatic diagnostics associated with anomalous lightning incidence during the summer 2012/2013 in Southeast Brazil.
The State of São Paulo in Southeast Brazil experienced during the 2012/2013 summer one of the most severe electrical storm events in recent years, causing various impacts to society, e.g. fires and fatalities. Thus, the objective of this work is to understand which mechanisms and climatic variabili...

Unfolding long-term late pleistocene–holocene disturbances of forest communities in the southwestern Amazonian lowlands.
Linking the distribution of plant species to geology has generally been biased by the over-simplification of landscape evolution and the lack of understanding of complex geological processes. The Amazonian lowlands have forests in different successional stages, and a growing perception is that such ...

Calibration and combination of monthly near-surface temperature and precipitation predictions over Europe.
A Bayesian method known as the Forecast Assimilation (FA) was used to calibrate and combine monthly near-surface temperature and precipitation outputs from seasonal dynamical forecast systems. The simple multimodel (SMM), a method that combines predictions with equal weights, was used as a benchmark...

Spatial and temporal changes in the land use and cover of the Paraíba Valley in São Paulo, Brazil: development of future scenarios.
The Paraíba Valley in São Paulo, Brazil, is marked by great transformations. The Brazilian economic cycles changed this region and transformed it into a great mosaic of pastures, forest fragments, and urban areas. Temporal studies on land use and cover have given information on these changes and e...

Towards a reproducible LULC hierarchical class legend for use in the southwest of Pará State, Brazil: a comparison with remote sensing data-driven hierarchies.
Land Use and Land Cover (LULC) classes defined by subjective criteria can diminish the significance of a study, hindering the reproducibility and the comparison of results with other studies. Having a standard legend for a given study area and objective could benefit a group of researchers focused o...
