Vale Institute of Technology ´s research that monitors water resources and the use and coverage of the soil in Rio Itacaiúnas basin, in southeastern Para, received an award during the 36th International Symposium on Remote Sensing of Environment. The event was held 11-15 May in Berlin, Germany.

The symposium, which brought together more than a thousand researchers, is the main forum for discussion on the subject worldwide. The Vale Institute of Technology (ITV), which first participated in the event, received the award 'Buddy Bear Berlin - Best Poster'. "We present the work in a poster that was available to participants for a whole day. The public was thus able to better understand the search results and discuss them directly with the author, "explained Peter Walfir, principal investigator of the work and who represented the Institute at the event.

The ITV competed with 399 other works presented in the symposium. "Among the advantages of our research is the methodology used, which shows the dynamics of use and occupation of the Itacaiúnas River basin, from the beginning of the occupation cycle, in the decade 70, a period that coincides with the launch of the first satellites of global coverage, launched by the Space Agency America, "said Pedro.

About the research

The Itacaiúnas Project collects and transmits real-time information on the features and the availability of water resources in the basin. Thus, the scientific community and the general public will benefit because the information will support the work of bodies such as the Civil Defense for the prevention of extreme events.

In terms of spatial dynamics study, the monitoring is made from images of Landsat satellites, provided by the US Geological Survey, pointing to successive decrease in vegetation cover over the last 40 years, where the forest gave way mainly to pasture.

In five different tiles you see the advancement of devastation, preferably linked to the expansion of pasture areas, which has led more than 20 square kilometers, equivalent to two million hectares, or half of the forest that existed in the 1970s. The year of 1973 was chosen to the research because it marks the beginning of the activities of the Carajás project. Back in 1985, it was when they started up the production and export of the ore produced in the region. In between each decade it is possible to note the impact that some economic activities and preservation policies were taken in place. The great contribution of the research was to show that the major mining projects are located in areas of environmental protection, in which the forest is conserved.
