Spatial dynamic modeling of deforestation in the Amazon.

New GIS technologies have been employed to support public policies and actions towards environmental conservation, aiming to preserve biodiversity and mitigate the undesirable side-effects of human activities. The spatio-temporal simulation of systems dynamics is an example of such new technologies ...

Biodiversity, ecosystem and commodities in Amazonia.

The Amazonian Region has undergone constant pressure from human activities in the past 100 years, with dramatic changes in the landscapes caused by significant impacts on a great number of rainforest biotic communities. Historical data show that the last pulse of expansion of the forest, which initi...

Aerosol and trace gas retrievals from remote sensing fire products.

Annually, anthropogenic fires devastate large areas of forest and grasslands over the world, releasing a large amount of greenhouse gases and aerosols into the atmosphere. This issue affects the environment, altering the atmospheric and surface radiation balance, besides the biogeochemical and hydro...

Carbon dynamic and emissions in Brazilian hydropower reservoirs.

As well documented by the scientific literature and strongly stated by the Intergovernmental Panel on Climate Change (IPCC), changes in the atmosphere composition, due to increasing emissions of greenhouse gases (GHG), may result in drastic environmental consequences, both in a regional and in a glo...

Climate change in the Amazon basin: tipping points, changes in extremes and impacts on natural and human systems.

The Amazon River system is the single, largest source of freshwater on Earth and its flow regime is subject to interannual and long-term climate variability, which translate into large variations in downstream discharge (Richey et al., 1989; Marengo and Nobre, 2001; Marengo 2004, 2005, 2006, 2007; M...

Entities and relations for agent-based modelling of complex spatial systems.

This work presents a contribution towards generalising the representation of geospatial entities and their relations for simulating complex spatial systems using the agentbased approach. We analyse the literature, and argue that each of the four types of relation is necessary. These relations can be...
