Launch of Collection 2.0
COLLECTION 2.0 OF ANNUAL LAND COVER AND LAND USE MAPS OF THE AMAZON (1985 - 2018)
MapBiomas Amazonia is a mapping tool to monitor land use changes across the Amazon and track pressures on its forests and natural ecosystems. The Amazon Land Cover and Land Use Annual Maps Collection 2.0 will be presented this Thursday, July 2 through the platform youtube.com/mapbiomasbrasil, at 9:30 am Peru, Ecuador and Colombia; 10:30 am Bolivia and Venezuela; 11:30 am Brazil.
This Collection 2.0 provides more than 3 decades of history of the Pan-Amazonian Land Cover and Land Use in annual maps from 1985 to 2018 with a resolution of 30 meters, according to Sandra Rios, one of the Technical Coordinators of MapBiomas Amazonia for Collection 2. The MapBiomas Amazonia platform offers the possibility of visualizing the maps at regional, national and even local level, identifying the areas covered with forests, natural fields, mangroves, agriculture and rivers, among other types. It is possible to understand the dynamics of land use changes inside and outside an Indigenous Territory or a Protected Area.
A great contribution in this Second Collection is that the platform not only offers maps but also statistics presented in tables and dynamic graphs with changes in use in the period the user requires, being freely accessible and downloadable, Ríos mentioned. The Second Collection of MapBiomas Amazonía has been generated by technicians and specialists from each of the countries that are part of the PanAmazonia, which allows for greater accuracy in the results.
In 2019, the First Collection covering the period 2000 - 2017 was presented and now, after intense work by members of the Amazon Network of Geo-referenced Socio-environmental Information (RAISG), and the technical collaboration of the MapBiomas Brazil team, this second collection seeks to contribute to the knowledge and analysis of the Amazon region in a comprehensive manner, also including data on the vectors of pressure on forests and other coverages such as mining, oil, roads and hydroelectric plants.
This unprecedented mapping incorporates the entire Pan-Amazon, from the Andes through the Amazon plain to the transitions with the Cerrado and Pantanal. The results as of 2018 show that the PanAmazon maintains 83.4% of its natural vegetation cover. Between 1985 and 2018, the Pan-Amazon lost 72.4 million hectares of its natural vegetation cover, an area equivalent to the territory of Chile. On the other hand, in the same period there was a 172% growth in agriculture and livestock area.
For RAISG, publishing the MapBiomas Amazonía 1985-2018 Collection 2.0 is an important step towards the objective of "building and promoting an integral vision of the Amazon considering political aspects of a region shared by eight countries, as well as socio-environmental aspects of great importance", mentioned Beto Ricardo, Coordinator of RAISG.
For Tasso Azevedo, general coordinator of MapBiomas, the launching of the Amazon MapBiomas Collection 2 is an important step to guarantee the mapping of all South America with a degree of spatial and temporal detail unprecedented in other continents. With the launch of MapBiomas Amazonia Collection 2.0 and the ongoing initiatives of MapBiomas Brazil, Argentina, Paraguay and Uruguay more than 90% of the territory of South America will be covered with historical land cover and land use map series. This database is invaluable for understanding the dynamics of natural resource use in the region, as well as contributing to climate modeling and the calculation of greenhouse gas emissions and removals due to land use and change in the region.
The information contained in the mapping tool is compatible and harmonized for all the countries in the region and makes it possible to know the state of vegetation cover, as well as trends, in the unit to be worked on. It also makes it possible to identify changes in land use in a given period (year, five-year period, decades, etc.) between 2000 and 2017. Thus, for example, it is possible to identify red zones, where there were important changes, such as the replacement of forest by agricultural crops or pastures.
At the level of the Amazon region, it is of great value to be able to have this information with a spatial resolution of 30 meters and with the detail and precision of analysis that allows the tool developed by MapBiomas Amazonía. All data processing is performed using automatic classification algorithms through data in the cloud, on the Google Earth Engine platform.
Initially, the land use mapping tool was developed by MapBiomas to be applied in Brazil, and had to be improved with input from RAISG member organizations to adjust the results and analysis to the geography of each of the Amazonian countries. In this way, the existing knowledge at the local level has made it possible to improve the tool and refine the interpretation of the data. The information from each of the countries is perfectly compatible with that from the rest of the countries, allowing a comprehensive view of the Amazon region. Likewise, the method used has made it possible to standardize the biomes included in the analysis: the nine Amazonian countries share the Amazon Biome, while Peru, Ecuador and Bolivia also share the Andes Biome.
In particular, it was necessary to take into account the altitudinal variations specific to the Andean Amazon. Currently, the mapping tool contemplates 21 classes, ranging from Andean glaciers to the forest formations of the Amazonian plains.
RAISG is the Amazonian Network of Geo-referenced Socio-environmental Information, a consortium of civil society organizations from Amazonian countries oriented to the socio-environmental sustainability of the Amazon, with the support of international cooperation. RAISG generates and disseminates knowledge, statistical data and geospatial socio-environmental information of the Amazon, elaborated with common protocols for all the countries of the region; it makes it possible to visualize the Amazon as a whole, as well as the threats and pressures it faces.
MapBiomas is a multi-institutional initiative that brings together universities, NGOs and technology companies that joined forces to contribute to the understanding of the transformations of the Brazilian territory from the annual mapping of land cover and land use in Brazil. In August 2019, MapBiomas Collection 4 was published with land cover and land use maps of Brazil from 1985 to 2018.
