Clusters agropecuários na emissão de gases de efeito estufa no nordeste brasileiro

Abstract

The present study seeks to carry out an analysis of the spatial distribution of Greenhouse Gas (GHG) emissions in the Brazilian Northeast, during the period from 2010 to 2019. Thus, it aims to contribute to the understanding of GHG emissions associated with agriculture and livestock in the region northeast. The information generated has the potential to provide valuable insights to guide climate change mitigation policies and promote sustainability. The main objective of the research is to identify the so-called agricultural clusters in the region and their possible spatial relationship with these emissions. To achieve this purpose, a spatial approach is adopted that investigates the contribution patterns of agricultural activities to climate change in the area. The results revealed that the 20 largest municipalities emitting greenhouse gases from Agriculture, among the 1,794, are responsible for 10.11% of all emissions in 2019, and in their spatial distribution, the formation of agricultural clusters in these municipalities predominates agricultural practices. Furthermore, through the use of the Global Moran Index, as well as the Local Spatial Association Indicator (LISA), four different types of spatial associations are identified: high-high, low-low, low-high and high-low. Analysis of these patterns points to the presence of significant GHG spillovers in areas with agricultural expansion in the Northeast.
