Carbon sequestration and nutrient cycling in agroforestry systems on degraded soils of Eastern Amazon, Brazil

Background:

Among various approaches to forest restoration, passive restoration via natural regeneration stands out as the most cost-efective option. However, the resilience of the forest is heavily influenced by factors such as water availability, soil integrity, and the presence of seed dispersers in the landscape. In situations where resilience is low, successful restoration relies on active human interventions. Unfortunately, many restoration projects, especially those involving smallholders, face budget constraints. In such circumstances, Agroforestry Systems emerge as a restoration strategy that combines both socio-economic and ecological advantages.

Restoring soil carbon and chemical properties through silvopastoral adoption in the Colombian Amazon region

Background:

The traditional livestock production in this region causes the loss of forest areas each year, leading to soil degradation and loss of biodiversity. Silvopastoral systems have become an attractive alternative with positive effects for the environment, society, and the regional economy. The study was conducted in two counties in the northwestern Colombian Amazon, which are representative of the hilly landscape typical for Silvopastoral systems implementation.

Agroforestry systems recover tree carbon stock faster than natural succession in Eastern Amazon, Brazil

Background:

Under the global context of climate change mitigation and adaptation, forests and land use practices in carbon sequestration and ecosystem resilience in the Amazon regions is of critical importance. Understanding the effectiveness of agroforestry systems in recovering tree carbon stock contributes to the broader discourse on sustainable land management, biodiversity conservation, and climate change mitigation strategies. Therefore, this study aims to address the gaps in knowledge regarding the carbon recovery potential of agroforestry systems and their role in sustainable land use in the Amazon region.

Carbon loss and removal due to forest disturbance and regeneration in the Amazon

Background:

Deforestation and forest degradation urges scientists to understand the dynamics of carbon loss and removal in the Amazon, particularly due to significant role of the Amazon rainforest in the global carbon cycle and the potential implications for climate change. By addressing this topic, the study aims to enhance our understanding of the Amazon's role in the global carbon cycle, provide insights into the spatial and temporal patterns of carbon loss and removal, and contribute valuable information for informing climate change mitigation strategies and tropical forest conservation efforts.

Discolouring the Amazon Rainforest: how deforestation is affecting butterfly coloration

Background

Butterflies are among the most colorful organisms in the world, and color plays a central role in many of their life-history strategies. However, sudden environmental changes, including anthropogenic disturbances such as habitat loss and fragmentation, could affect the efficacy of coloration strategies in these and other animals. Therefore, this study aims to investigate how deforestation is affecting butterfly coloration in the Amazon Rainforest and to provide insights into the potential consequences of anthropogenic disturbances on these beautiful creatures.

Do primary rainforest tree species recruit into passively and actively restored tropical rainforest?

Background

In many restoration projects, recruitment is dominated by a low diversity of regionally-abundant pioneer species and species with small, easily dispersed seeds. These species are characteristic of secondary rainforest and do not include the far more diverse suite of species characteristic of the original, primary rainforest. As restoring ecosystem processes is one of the central goals of restoration, this raises the question of which, if any, of the available rainforest restoration methods may be used to promote the recruitment of primary rainforest species.

The effect of ecological restoration methods on carbon stocks in the Brazilian Atlantic Forest

Background

There is a critical need for effective ecological restoration strategies in the Brazilian Atlantic Forest, one of the most threatened biodiversity hotspots globally, with extensive areas degraded due to human activities such as deforestation and land use change. Especifically, to understanding how different restoration methods impact carbon sequestration in this ecosystem and promote the recovery of this vital ecosystem.

Direct seeded and colonizing species guarantee successful early restoration of South Amazon forests

Background

South Amazon forests have been highly deforested, including the legally protected riparian forests. Direct seeding is a low cost method, easy-to-implement at large scale. The authors emphasize the imperative to reduce the costs and enhance the outcomes of restoration efforts, which have become mainstream solutions in countering biodiversity loss and climate change around the world.

An overview of forest loss and restoration in the Brazilian Amazon

Background:

The accelerated process of forest loss and degradation in the Brazilian Amazon began in the 1970s due to government-promoted economic development initiatives. This led to significant deforestation, with approximately 20% (780,967 km2) of the region being affected . Nevertheless, the region still lacks scientific studies that reinforce the choice of best practices for forest restoration, and the information currently available is not enough to quantify what has already been recovered or the potential area to be restored.

Evaluating the success of direct seeding for tropical forest restoration over ten years

Background

The main causes of deforestation in the Amazon are large-scale agriculture and cattle ranching, which have led to the loss of millions of hectares of forest. To address this issue, different mechanisms have been implemented since 2005 to reduce deforestation and increase forest restoration.  However, highly modified, degraded areas with a long history of use may take a long time to regenerate naturally or may not recover into a secondary forest. Therefore, active restoration methods are needed to accomplish this massive obligation.
