International organizations, advocacy coalitions, and domestication of global norms: debates on climate change in Canada, the US, Brazil, and India.
National climate policies are shaped by international organizations (IOs) and global norms. Drawing from World Society Theory and the Advocacy Coalition Framework (ACF), we develop two related arguments: (1) one way in which IOs can influence national climate policy is through their engagement in ma...

Widespread reduction in sun-induced fluorescence from the Amazon during the 2015/2016 El Niño.
The tropical carbon balance dominates year-to-year variations in the CO2 exchange with the atmosphere through photosynthesis, respiration and fires. Because of its high correlation with gross primary productivity (GPP), observations of sun-induced fluorescence (SIF) are of great interest. We develop...

Future climate change scenarios in Central America at high spatial resolution.
The objective of this work is to assess the downscaling projections of climate change over Central America at 8-km resolution using the Eta Regional Climate Model, driven by the HadGEM2-ES simulations of RCP4.5 emission scenario. The narrow characteristic of continent supports the use of numerical s...

Tropical land carbon cycle responses to 2015/16 El Nino as recorded by atmospheric greenhouse gas and remote sensing data.
The outstanding tropical land climate characteristic over the past decades is rapid warming, with no significant large-scale precipitation trends. This warming is expected to continue but the effects on tropical vegetation are unknown. El Nino-related heat peaks may provide a test bed for a future h...

Investigating the mechanisms responsible for the lack of surface energy balance closure in a central Amazonian tropical rainforest.
This work investigates the diurnal and seasonal behavior of the energy balance residual (E) that results from the observed difference between available energy and the turbulent fluxes of sensible heat (H) and latent heat (LE) at the FLUXNET BR-Ma2 site located in the Brazilian central Amazon rainfor...

Historical carbon fluxes in the expanding deforestation frontier of Southern Brazilian Amazonia (1985–2012).
In tropical areas, pioneer occupation fronts steer the rapid expansion of deforestation, contributing to carbon emissions. Up-to-date carbon emission estimates covering the long-term development of such frontiers depend on the availability of high spatialtemporal resolution data. In this paper, we p...

Water sustainability at the River Grande basin, Brazil: an approach based on the barometer of sustainability.
Water resources are fundamental for the social and economic development of a country and sustainability is the best approach to treat water-related problems. Therefore, sustainability studies of water resources are deemed urgent. Sustainability analysis methods should enable space-temporal monitorin...

Evaluation of optical and radar images integration methods for LULC classification in Amazon region.
The main objective of this study is to evaluate different methods to integrate (fusion and combination) Synthetic Aperture Radar (SAR) Advanced Land Observing Satellite (ALOS) Phased Arrayed L-band SAR (PALSAR-1) (Fine Beam Dual mode-FDB) and LANDSAT images in order to identify those which lead to h...

Modelling land sharing and land sparing relationship with rural population in the Cerrado.
Agricultural expansion and intensification enabled growth of food production but resulted in serious environmental changes. In light of that, debates concerning sustainability in agriculture arises on scientific literature. Land sharing and land sparing are two opposite models for framing agricultur...

Multi-temporal flood mapping and satellite altimetry used to evaluate the flood dynamics of the Bolivian Amazon wetlands.
The Bolivian Amazon wetlands are extensive floodplains distributed over the Mamore, Beni, Madre de Dios and Guapore Rivers. Located within the upper Madeira River Basin, the wetlands play important roles in regulating the biogeochemical processes and hydrological cycle of the region. In addition, th...

Reptile species persistence under climate change and direct human threats in north-western Argentina.
Protected areas have been established historically in residual places where the potential for extractive uses is low, implying that places at risk are usually under-protected. Argentina is no exception, with few protected areas established in productive regions that are prone to conversion. Here, us...
