Establishing Protected areas (PAs) could displace or cause ‘leakage’ of deforestation into adjacent areas. Such leakage would potentially offset PAs' conservation effort by jeopardizing forest conservation goals and impeding financial mechanisms such as Reducing Emissions from Deforestation and forest Degradation - REDD+. Here we investigate forest...

Habitat loss is the leading cause of the global decline in biodiversity, but the influence of human pressure within the matrix surrounding habitat fragments remains poorly understood. Here, we measure the relationship between fragmentation (the degree of fragmentation and the degree of patch isolation), matrix condition (measured as the extent of h...

Habitat loss is the leading cause of global biodiversity decline, but the influence of human pressure within the matrix surrounding habitat fragments remains poorly understood. Here we measure the relationship between fragmentation, matrix condition (measured as the extent of high human footprint levels), and the change in extinction risk of 4,327...

Land free of direct anthropogenic disturbance is considered essential for achieving biodiversity conservation outcomes but is rapidly eroding. In response, many nations are increasing their protected area (PA) estates, but little consideration is given to the context of the surrounding landscape. This is despite the fact that structural connectivit...

protected areas (pAs) are a foundational and essential strategy for reducing biodiversity loss. However, many pAs around the world exist on paper only; thus, while logging and habitat conversion may be banned in these areas, illegal activities often continue to cause alarming habitat destruction. in such cases, the presence of armed conflict may ul...

Este documento presenta un análisis inicial de las causas de la degradación forestal en Colombia a partir de la revisión de información secundaria y de información espacialmente explícita disponible, en donde se abordan las causas directas de este proceso.

La dificultad de definir y cuantificar la degradación de bosques es una limitación que la mayoría de los países en desarrollo tienen para incluir compromisos de reducción de emisiones en el contexto del enfoque de Reducción de Emisiones por Deforestación y Degradación de Bosques, Aumento de las Reservas de Carbono, Conservación y Manejo Sostenible...

Propuesta metodológica para la estimación y monitoreo de la degradación forestal causada por la tala selectiva en Colombia.

The southern Yucatán (SY) has been recognized as a hotspot of biodiversity with great risk of deforestation. Land change analysis, based on classified Landsat TM and ETM + satellite imagery (1990, 2000 and 2006), was used to estimate the annual deforestation rates of 141 land management units of the SY, and spatial patterns of forest fragmentation...
