Forest transitions in mosaic landscapes: smallholder’s flexibility in land-resource use decisions and livelihood strategies from World War II to the present in the Amazon estuary.
The question of how smallholders of the Amazon estuary, locally known as cabolcos, have adapted their land use systems to produce resources during booms and busts is analyzed in this article. We draw upon more than 50 years of census data and more than 30 years of remotely sensed land-cover data to ...

Regional climate modelling in CLARIS-LPB: a concerted approach towards twentyfirst century projections of regional temperature and precipitation over South America.
The results of an ensemble of regional climate model (RCM) simulations over South America are presented. This is the first coordinated exercise of regional climate modelling studies over the continent, as part of the CLARIS-LPB EU FP7 project. The results of different future periods, with the main f...

Development and challenges in Brazilian municipal solid waste management.
The generation of municipal solid waste (MSW) has increased over time in Brazil, along with changes in waste quality, which gives rise to discussions regarding the importance of properly managing and disposing of these wastes. Currently, issues involving the management of MSW have a central focus in...

Multi-scale participatory scenario methods and territorial planning in the Brazilian Amazon.
In recent years, discussions regarding scenarios methods for the Brazilian Amazon have been mostly explored from the sole perspective of deforestation concerns. This paper proposes an original approach using participatory scenarios as a method that may be able to put in perspective, at different lev...

Forest edge burning in the Brazilian Amazon promoted by escaping fires from managed pastures.
Understanding to what extent different land uses influence fire occurrence in the Amazonian forest is particularly relevant for its conservation. We evaluate the relationship between forest fires and different anthropogenic activities linked to a variety of land uses in the Brazilian states of Mato ...

Identifying areas susceptible to desertification in the Brazilian northeast.
Approximately 57 % of the Brazilian northeast region is recognized as semi-arid land and has been undergoing intense land use processes in the last decades, which have resulted in severe degradation of its natural assets. Therefore, the objective of this study is to identify the areas that are susce...

Natural and anthropogenic influence on soil erosion in a rural watershed in the Brazilian southeastern region.
Human activities have been driven land cover, provoking acceleration of the erosive process and alteration on the soil characteristics. To explore the effects of human disturbance, we investigated the influences of natural and anthropogenic features on soil quality and soil erosion indicators (EI) w...

Building a hybrid land cover map with crowdsourcing and geographically weighted regression.
Land cover is of fundamental importance to many environmental applications and serves as critical baseline information for many large scale models e.g. in developing future scenarios of land use and climate change. Although there is an ongoing movement towards the development of higher resolution gl...

High-speed video and electric field observation of a negative upward leader connecting a downward positive leader in a positive cloud-to-ground flash.
It has been discussed in past papers if a positive leader propagates in a stepped fashion or not. Some studies state that, in some positive cloud-to-ground flashes, the electric field pulses observed just before the connection of the positive leader to ground could be a manifestation of the stepping...
