Extensive forest restoration is a key strategy to meet nature-based sustainable development goals and provide multiple social environmental benefits
In degraded tropical pastures, active restoration strategies have the potential to facilitate forest regrowth at rates that are faster than natural recovery, enhancing litterfall, and nutrient inputs floor. We evaluated litterfall dynamics under four treatments: plantation (entire area planted), tree islands (planting in six patches of three sizes), control (same age regeneration), young secondary (7–9-yr-old regeneration). Treatments were established plots 50 × m replicate sites southern...
Abstract Brazil's riparian forests are continuously threatened by conversion into agricultural areas, causing not only degradation and loss of vegetation but also negative changes in soil properties ecosystem services. In order to select variables that affected evaluate whether forest structure can be used as a proxy for services, two watersheds eastern Amazon were chosen study area which four levels identified (very high, moderate low), based on canopy openness height. Vegetation structural...
Tropical forests provide essential environmental services to human well-being. In the world, Brazil has largest continuous area of these forests. However, in state Maranhão, eastern Amazon, only 24% original forest cover remains. We integrated and analyzed active fires, burned area, land use cover, rainfall, surface temperature datasets understand fragmentation fire dynamics from a remote sensing approach. found that Maranhão Amazon region had net reduction 31,302 km2 between 1985 2017, with...
Riparian forests provide ecosystem services that are essential for human well-being. The Pepital River is the main water supply Alcântara (Brazil) and its disappearing. This affecting volume distribution in region. Promoting forest restoration imperative. In deprived regions, success depends on integration of ecology, livelihoods traditional knowledge (TEK). this study, an interdisciplinary research framework proposed to design riparian strategies based ecological data, TEK social needs....
Resumo O Mosaico Gurupi esta localizado entre o oeste do Maranhao e leste Para, na Area de Endemismo Belem, que embora seja a regiao mais desmatada Bioma Amazonico no Brasil, preserva uma diversidade cultural biologica superlativa. mosaico engloba seis Terras Indigenas (Alto Turiacu, Awa, Caru, Arariboia, Rio Pindare Alto Guama) Unidade Conservacao (Reserva Biologica Gurupi). Essas areas protegidas conservam os principais remanescentes florestais da garantem manutencao servicos...
Partial harvesting has been proposed as a key aspect to implementing ecosystem management in the Canadian boreal forest. We report on replicated experiment located mixedwoods of Northwestern Quebec. In winter 2000–2001, two partial treatments, one using dispersed pattern, and second, which created (400 m2) gap were applied 90-year-old aspen-dominated mixed stand. The design also included clear cut control. Over course following eight years, live tree, coarse woody debris, regeneration ground...
Abstract Multi‐year studies comparing changes in litterfall biomass and nutrient inputs sites under different restoration practices are lacking. We evaluated dynamics at 5 yr after a decade of recovery four treatments (natural regeneration—no planting, plantation—entire area planted, tree islands—planting patches, reference forest) multiple an agricultural landscape southern Costa Rica. inter‐planted two native species ( Terminalia amazonia Vochysia guatemalensis ) naturalized N‐fixing Inga...
O Centro de Endemismo Belém (CEB) -região biogeográfica localizada entre os rios Tocantins e Pindaré- é a área mais desmatada da Amazônia. Estudar biota do solo dos remanescentes florestais áreas em regeneração (capoeiras) CEB fundamental para promover práticas agrícolas sustentáveis orientar ações restauração degradadas. Dessa forma, o objetivo desse estudo foi identificar principais determinantes composição diversidade grandes táxons macrofauna (uso atual solo, núcleos geográficos,...
As florestas ripárias provêem serviços ecossistêmicos essenciais à humanidade, mas estão sendo degradadas em um ritmo acelerado na Amazônia. Esse estudo teve como objetivo quantificar os estoques de carbono acima e abaixo do solo com quatro níveis degradação (muito alta, média baixa) duas microbacias (Rio Pepital Rio Grande) Alcântara (Maranhão), Amazônia Oriental. Foram instaladas 24 parcelas permanentes 1.000 m2, onde a vegetação (árvores, arbustos, herbáceas, lianas palmeiras), necromasa...
Brazil's Cerrado region, a tropical savanna ecosystem globally recognized for its rich and endemic biodiversity (1) importance in water regulation (2), faces escalating threats to environmental services due deforestation (3). The state of Maranhão, with an area 33 million hectares, contains both (65%) Amazon (35%) biomes (4). In the state's Amazonian predatory has led poverty violence against traditional Indigenous peoples which is currently deliberating zoning policies, must ensure that...
Amazon deforestation damages nature, people, and their closer biocultural relationship, eroding fundamental elements for its reproduction. The recognition use of traditional knowledge to plan implement restoration efforts are essential success. This study identified forest tree species value indigenous communities, quilombolas, settled farmers in Maranhão state, eastern Brazilian Amazon. Semi-structured interviews, informal conversations, Free Lists, guided walks were carried out three...
<title>Abstract</title> Extensive forest restoration is a key strategy to meet nature-based sustainable development goals and provide multiple social environmental benefits. Yet achieving at scale requires cost-effective methods. Tree planting in degraded landscapes popular but costly method, which often results less biodiverse forests when compared natural regeneration techniques under similar conditions. Here, we assess the current spatial distribution of pantropical (from 2000-2016) use...
O presente trabalho teve por objetivo o aproveitamento da água residuária proveniente de um sistema biológico tratamento esgotos domésticos como alternativa à fertirrigação convencional viveiros florestais, visando a produção mudas Croton floribundus (capixingui) e Copaifera langsdorffii (Copaíba) via subirrigação. As variáveis avaliadas mensalmente foram altura diâmetro do coleto muda e, ao final experimento, peso matéria seca parte aérea raiz, área foliar, razão aérea/ análise nutricional...
Tropical forest restoration strategies have the potential to accelerate recovery of nutrient cycles in degraded lands. Litter production and its decomposition represent main transfer organic material nutrients into soil substrate. We evaluated litter production, accumulation on floor, under three strategies: plantation (entire area planted with trees), island (trees patches different sizes) control (natural regeneration) plots. also compared young secondary (7-9 yr). Restoration treatments...
Este trabalho teve por objetivo estudar a viabilidade do uso de águas residuárias provenientes um sistema biológico tratamento esgotos domésticos como alternativa à fertirrigação convencional viveiros florestais, visando produção mudas Eucalyptus grandis via subirrigação contínua. As variáveis avaliadas foram: altura, diâmetro coleto, peso da matéria seca parte aérea e raiz, área foliar, razão raiz/parte concentração nutricional foliar. O desenvolvimento das plantas, em geral, foi superior...
This article explores factors that incentivize farmers to adopt diversification practices in agriculture (agroecological transition). The research was conducted between January 2013 and November 2017, involving eight agrovilas (rural villages built for relocated communities) the Alcântara municipality, Maranhão– Brazil. Activities included training courses, workshops, farmer's field visits, implantation of productive systems, continuing technical assistance. Semi-structured interviews were...
