The carbon sink of secondary and degraded humid tropical forests

Background:

The Forest and Land use Declaration from the 26th Climate Change Conference of the Parties underscores the crucial role of tropical moist forests  as a nature-based solution to address climate and ecological emergencies. However, the Amazon, Borneo, and Central Africa forests experience ongoing forest cover losses due to various anthropogenic drivers. This has led to a mosaic of recovering forests at different stages post-disturbance, with limited understanding of their impact on forest carbon dynamics.

El aumento de la deforestación en la cuenca del río Madre de Dios, Amazonía peruana, incrementaría la escorrentía superficial y la concentración de sedimento

Background

En 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 1984-2020

Background:

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.

Metodología de reforestación y restauración de paisajes amazónicos degradados por minería: análisis de costos

Background:

La actividad minera aurifera artisanal conlleva la deforestación, degradación del suelo, pérdida de biodiversidad y contaminación por mercurio. A medida que esta actividad crece, surge la necesidad imperante de desarrollar metodologías que permitan la reforestación y restauración de las zonas degradadas en los países amazónicos.

Artisanal gold mining activity leads to deforestation, soil degradation, loss of biodiversity and mercury contamination. As this activity grows, there is an urgent need to develop methodologies that allow reforestation and restoration of degraded areas in Amazonian countries.

Mapping tree species vulnerability to multiple threats as a guide to restoration and conservation of tropical dry forests

Background:

The global biodiversity crisis is exacerbated by anthropogenic threats such as climate change, habitat conversion, and overexploitation. Evaluating the susceptibility of ecosystems and species to these threats is imperative for strategic and cost-effective planning of restoration and conservation efforts.

Survival and Early Growth of 51 Tropical Tree Species in Areas Degraded by Artisanal Gold Mining in the Peruvian Amazon

Background:

Artisanal and small-scale gold mining has dramatically changed the landscape of tropical ecosystems, completely removing the soil and vegetation and polluting it with mercury disposals. In order to recover these degraded spaces, reforestation projects need to enhance their knowledge of restoration species growth and survival rates under different site conditions, as well as their fertilization needs.

Goals:

The authors of this study aim to (1) test 51 species with potential for ecological restoration and/or forest rehabilitation; (2) assess the potential for biochar amendments for use in reforestation efforts; and (3) explore species performance regarding their contrasting wood density traits.

Biochar Effects on Two Tropical Tree Species and Its Potential as a Tool for Reforestation

Background:

Although biochar is starting to be recognized as a potential soil fertilizer, most of the current studies are focused on the growth response of herbaceous crops and not on the impacts of biochar on tree development.

Goals:

The authors measure the survival rate, growth, and biomass accumulation of the seedlings of two tropical tree species Terminalia amazonia (“terminalia”) and Guazuma crinita (“bolaina”) under abandoned gold mine conditions: nutrient-poor and sandy soil. The seedlings were tested under six different treatments (three doses of biochar, with and without fertilizer) for six months.

Protocolo: Mantenimiento y Fertilización de Parcelas de Reforestación

Background:

Como parte del trabajo de investigación que viene desarrollando el Centro de Innovación Científica Amazónica (CINCIA), se ha realizado la instalación de parcelas experimentales de reforestación en áreas degradadas por actividad minera en Madre de Dios.

As part of the research work being carried out by the Center for Amazonian Scientific Innovation (CINCIA), experimental reforestation plots have been installed in areas degraded by mining activity in Madre de Dios.

Assessing the Carbon Capture Potential of a Reforestation Project

Background:

Reforestation projects are receiving more and more attention due to their potential to sequester carbon and limit the increase of the global average temperature above 2 Celsius degrees. Consequently, is important to evaluate the accuracy of the GHG capture results made by the increasingly funded reforestation platforms.

Disrupted montane forest recovery hinders biodiversity conservation in the tropical Andes

Background

In the U.N. Decade on Restoration, recovering degraded forests is a high priority. Andean montane forests are a biodiversity hotspot, storing large quantities of carbon, and providing many sources for human livelihood. Many parts of the Andean forests are recovering after agriculture abandonment, but it is not yet known how the dynamics of these recovery processes progress over time. Knowledge of forest regeneration trajectory is crucial for further restoration planning.
