Abstract The Balbina hydropower dam in the Central Amazon basin, established Uatumã River 1980s, is emblematic for its socio‐environmental disaster. Its environmental impacts go far beyond reservoir and dam, however, affecting floodplain forests (igapó) downstream area (dam shadow), which have been assessed using a transdisciplinary research approach, synthesized this review. Floodplain tree species are adapted to regular predictable flood pulse, with high‐ low‐water periods occurring during...
Abstract Extreme climatic events and anthropic disturbances affect the hydrological regime of Amazonian rivers connected floodplain forests. This study aims to investigate impacts Balbina hydroelectric power plant on forests Uatumã River, in Central Amazon. For this, tree age diameter increment from most abundant species three different topographic levels were obtained analyzed affected area downstream dam (Uatumã River) compared an undisturbed site (Abacate affluent) considering structure...
Groundwater has been used intensively throughout Brazil. In southern Amazonas state, the water supplies of some municipalities are derived exclusively from wells. Yet this region generally no wastewater treatment, leading to potential contamination underground water. We classified and mapped vulnerability groundwater in urban peri-urban area Humaitá State. GOD method (Groundwater occurrence; Overall Lithology unsaturated zone; Depth table) score classes. The results revealed existence...
No presente artigo são analisados o padrão do desmatamento na Amazônia Legal (AML), as relações entre desmatamento, atividades agropecuárias e a fiscalização ambiental AML, além de revisar gestões dos diferentes regimes políticos que governaram Brasil. O objetivo destas abordagens é realizar periodizações da evolução AML. Com base no espacial, agentes vetores AML definidos dois grandes períodos, com divisor temporal nos anos 2000. Por outro lado, considerando os modelos ocupação...
O Índice de Área Foliar (IAF) é determinante nos processos trocas massa e energia ecossistemas, sendo fundamental para o entendimento das mudanças no clima regional na dinâmica do ecossistema. objetivo deste trabalho foi analisar, por meio da geoestatística, a variabilidade dependência espacial dos valores índice área foliar em áreas naturais campo 'baixo', 'alto' floresta transição Sul Amazonas. Os IAF foram determinados numa malha regular com 33 pontos cada estudada, aquisição dados feita...
