Impacts of Disturbance
How much deforestation in sub-Saharan Africa has been caused by mining?BACKGROUND:Sub-Saharan Africa has become a major mining hub due to its vast mineral resources, which has led to significant economic growth and investment in the region since the early 2000s. However, the expansion of mining activities, especially post-2000, has raised concerns about their environmental impact, particularly in terms of deforestation and habitat disruption. The paper aims to assess the extent of deforestation caused by mining activities in Sub-Saharan Africa, employing geospatial and statistical analysis to compare areas with and without mining operations.

Expanding forest carbon sinks to mitigate climate change in AfricaBACKGROUND:Forests play a crucial role in climate change mitigation by acting as carbon sinks that sequester atmospheric CO2. African forests, covering 22% of the continent, provide substantial benefits but are under threat from deforestation and degradation. A comprehensive strategy that integrates social, economic, and environmental aspects is essential to preserve their ability to capture carbon effectively. The authors seek to examine the relationship between forest loss and increased CO2 emissions in Africa. Open access copy available |
Uso del efecto de borde de la vegetación para la restauración ecológica del bosque tropicalBackgroundEl artículo aborda la fragmentación de hábitats causada por la deforestación, lo que genera cambios en los procesos ecológicos, específicamente el efecto de borde. Este efecto se caracteriza por la generación de microclimas variables y condiciones dinámicas del suelo en la interfase entre el bosque nativo y la vegetación adyacente inducida. A nivel global, los bosques tropicales han sufrido una deforestación considerable, impactando negativamente la biodiversidad y los ciclos ecológicos. Available with subscription or purchase |

El aumento de la deforestación en la cuenca del río Madre de Dios, Amazonía peruana, incrementaría la escorrentía superficial y la concentración de sedimentoBackgroundEn la Amazonía sudeste del Perú, se encuentra la cuenca del río Madre de Dios, uno de los focos de biodiversidad mundial. Sin embargo, la alta tasa de deforestación en la cuenca del río Madre de Dios genera una gran preocupación pues la cobertura vegetal es de vital importancia en la conservación de los ríos y suelos. En ausencia de la cobertura vegetal, la precipitación impacta directamente en el suelo y la cantidad de agua que no puede ser infiltrada discurre a través de arroyos definidos por la topografía de la cuenca.

Influencia de la minería aurífera aluvial en la geodinámica fluvial del río Madre de Dios, Amazonía peruana, en el periodo 1984-2020Background:La dinamica de la rios es escencial en mantener la extraordinaria biodiversidad de los bosques tropicales. Sin embargo en la Amazonia de Madre de Dios (Peru) estos rios estan siendo fuertemente impactados por la mineria artesanal de oro, que hasta la fecha ha deforestado mas de 100 000 ha de bosque amazonico. La mineria aluvial es de especial preocupacion pues puede alterar la dinámica fluvial natural de los ríos al modificar el ancho, la profundidad, la sinuosidad y la estabilidad del canal.

Deforestation-Induced Climate Change Reduces Carbon Storage in Remaining Tropical ForestsBackground:Deforestation of tropical forests alters the biophysical properties of the forest's surface, which contributes to regional warming and drying. These environmental changes, in turn, could impact non-degraded forests, reducing the rates of photosynthesis and increasing the release of carbon through autotrophic respiration, as well as the risk of a wildfire. Consequently, it is important to improve the accuracy of carbon and climate benefits of a land management action (e.g., avoided deforestation) to enable a more effective valuation of the carbon credits issued for a specific project.

Aboveground carbon responses to experimental and natural hurricane impacts in a subtropical wet forest in Puerto RicoBackgroundCarbon sequestration is a major climate mitigating process. Tropical forests in particular sequester high amounts of carbon, however disturbance events such as storms can alter the ability of forests to sequester more carbon. Hurricanes create forest gaps and increase ground debris which both provide resources that may promote plant recruitment and growth. Open access copy available |
