    Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands.

    O território do norte paraense possui 270.040,7 km², distribuídos em nove municípios: Alenquer, Almeirim, Curuá, Faro, Monte Alegre, Óbidos, Oriximiná, Prainha e Terra Santa. Tal área ocupa 22% do estado do Pará, o equivalente à soma dos estados de São Paulo e Sergipe (IBGE, 2019). Em 2019, esse território abrigava uma população estimada em apenas 344.385 habitantes (4% da população total do Pará). Além disso, seu incremento populacional tem ficado abaixo da média do restante do estado. De fato, a população do Norte do Pará aumentou somente 51.480 habitantes entre os anos 2000 e 2019.

    Tree root systems stabilize hillslopes and riverbanks, reducing landslide risk, but related data for the humid tropics are scarce. We tested fractal allometry hypotheses on differences in the vertical and horizontal distribution of roots of trees commonly found in agroforestry systems and on shear strength of soil in relation to root length density in the topsoil. Proximal roots of 685 trees (55 species; 4–20 cm stem diameter at breast height, dbh) were observed across six landscapes in Indonesia.

    Forest conversion to agriculture can induce the loss of hydrologic functions linked to infiltration. Infiltration-friendly agroforestry land uses minimize this loss. Our assessment of forest-derived land uses in the Rejoso Watershed on the slopes of the Bromo volcano in East Java (Indonesia) focused on two zones, upstream (above 800 m a.s.l.; Andisols) and midstream (400–800 m a.s.l.; Inceptisols) of the Rejoso River, feeding aquifers that support lowland rice areas and drinking water supply to nearby cities.

    Neste relatório avaliamos a situação da exploração madeireira no estado do Pará entre agosto de 2017 e julho 2018. Para tanto, comparamos inicialmente as informações das Autorizações para Exploração Florestal (Autefs) operacionais no período, emitidas pela Semas-PA (Secretaria Estadual de Meio Ambiente e Sustentabilidade), com imagens de satélite processadas para verificar a consistência e execução dessas autorizações.
