The rate of deforestation of the Gran Chaco Region during December 2017, at 31,742 hectares, was considerably lower than the 61,748 hectares in November 2017. This represented a deforestation rate of 1,024 hectares per day, compared with 2,058 hectares per day in November. By way of comparison, the loss of 31,742 hectares of Chaco forest is equivalent to an area more than 2.8 times that of the city of Asunción and equivalent to more than 1.6 times that of the city of Buenos Aires.
Argentina accounted for the largest share of the 31,742 hectares of woodlands that was converted to agricultural and other uses in December 2017, with 47% of the total deforested area, followed by Paraguay with 43% and Bolivia with 10%. In the specific case of Paraguay, the average rate of deforestation was 443 hectares per day, compared with 483 hectares per day for Argentina, and 98 hectares per day for Bolivia..
The locations in the Gran Chaco that experienced the greatest changes of land use in each country were as follows: in Paraguay, the Municipality of Mariscal Estigarribia in the Department of Boquerón (8,897 hectares); in Argentina, the Department of Chaco in the Province of Almirante Brown (1,986 hectares); and in Bolivia, the Municipality of Charagua in the Department of Santa Cruz (2,014 hectares). The geographical distribution of the deforestation of the Gran Chaco is available, disaggregated by municipality.
flood plains, it was possible to discern a reduction in the area under water in general terms in December 2017 in the combined water systems of the Gran Chaco, which covered a total of 1,954,752 hectares, an area considerably lower than the 3,224,402 hectares under water in November 2017. It is important to note that because these images are made to a spatial resolution of 250 metres, there may well be smaller bodies of water that have gone unregistered.
From 1 to 31 December 2017 a total of 26,853 focuses were identified in the four countries of the Gran Chaco region (Argentina, Brazil, Bolivia and Paraguay), representing a considerable reduction from the number of heat focuses detected during November 2017 (56,446). Some 51% of the total heat focuses were detected in Argentina, 38% in Paraguay, and 11% in Bolivia.

Guyra Paraguay also has these files available in PDF format and will also upload the files in Google Earth format to the website of “Amigos de Guyra Paraguay”.
