| Abstract | Fires in Amazonia are a major source of greenhouse gases to the atmosphere, changing carbon and nutrient cycles and severely affecting vegetation characteristics. Descriptions and summary of how fires occur have thus broad interest for environmental studies. For example, mathematical relations that can represent fire activity and effects are strongly needed in surface models for climate studies in the region. As indicated by previous studies, contemporary patterns of fire activity in the region can be largely explained by a combination of climate and land-use dynamics. Here we present analyses that explore spatial relationships between fire activity and connection to markets, a major land-use driver in Amazonia. Data on fire activity are based on remote-sensing detections from MODIS sensor between 2001 and 2010. Information on connection to markets for the year of 2006 was calculated considering Euclidean distances and topological connections to important consumption markets, weighted by paved and non-paved roads network. Confronting both datasets, we found that the number of fire detections was different according to the proximity to consumption markets. In summary, low fire activity was related to either very low or very high connectivity to markets. High fire frequencies, on the other hand, were related to intermediate values of connectivity to markets. These broad-scale patterns are consistent with the observed dynamics of deforestation frontiers. Land-cover change in areas with low connectivity to markets is generally difuse. Very high connectivity can be associated with places where fires do not figure as a tool in most cases, such as large-scale agriculture and urbanized areas. These results have thus important implications for environmental studies in the region, by contributing to current descriptions of the relations between fire and land-use change in areas that can provide important ecossystem services. | |||
