Método aglomerativo de Ward aplicado ao rendimento agregado da castanha-do-brasil no estado do Amazonas, ano de 2019

Abstract

The Non-Timber Forest Product – PFNM is of great importance for the regional deve- lopment of populations that work in forest management. Among the NTFPs, Brazil nut (Bertholletia Excelsa) stands out, also known as Brazil nut or Amazon nut, native to the Amazon region, a growing and relevant product for the economy and environment of the State. from Amazon. Today the Brazil nut, in addition to being extracted, is cul- tivated in conservation units, despite the delay in the production of urchins, today there are already cataloged and georeferenced cultivation species in the region. In view of this, this work aims to analyze the aggregate yield by Ward's agglomerative method, analyzing the similarity and dissimilarity in the extraction and cultivation of Brazil nut between the sub-regions of the State of Amazonas. In order to disseminate data and information from this study to the actors of regional public policies in the State, and lead to the development of Non-Timber Forest Products - PFNMs, especially Brazil nuts. It is worth mentioning that although Brazil nut production is concentrated in spe- cific sub-regions and municipalities, in some sub-regions the production is high for little labor, while other sub-regions have production as high as, however, with a greater number of Manpower, thus decreasing its Aggregate Income, in other sub-regions there is no production or it is very low, showing that the supply chain in the state of Amazonas is not very efficient. The research is qualitative-quantitative, exploratory in nature, and the methodology to be used will be cluster analysis, or cluster analysis, hierarchical and multivariate, and its connection is performed by Ward's Method. The research data were extracted from SIDRA/IBGE and IDAM in the year 2019. We found in this research that the Jutaí/Solimões/Juruá sub-region had the highest yield for ex- tractivism with 32.74%, while the Madeira sub-region had the highest yield for cultiva- tion with 31.22%, these being the most dissimilar among all the other 9 sub-regions.
