Efeitos socioambientais das enchentes de 2013/14 do Rio Madeira no extrativismo da castanheira do Brasil (Bertholletia Excelsa H. & B) e da seringueira (Hevea Brasiliensis Müll. Arg.) na Resex Lago do Capanã Grande, Manicoré-Am.

Abstract

The causes and socio-economic consequences of mortality in Brazil nut trees (Bertholletia excelsa H. & B) and rubber trees (Hevea brasiliensis Mev. Arg.) were studied in the Lago do Capanã Grande extractive reserve, Manicoré, Amazonas. Mortality was associated with the 2013-2014 extreme flood in the Madeira River by statistically analyzing the mortality of georeferenced individuals of the two species in four communities, considering diameter at breast height (DBH) and the time under root asphyxia in eight Brazil nut and five rubber stands. To estimate the impact and socioeconomic consequences of the extreme event on communities, interviews were conducted with 15 families who were residing in the study area and who had extraction of rubber and Brazil nuts as structural economic activities for their family income.
