Tropical surface gold mining: A review of ecological impacts and restoration strategies

BACKGROUND

Filling a void: Analysis of early tropical soil and vegetative recovery under leguminous, post-coal mine reforestation plantations in East Kalimantan, Indonesia

BACKGROUND

Surface mining is a common practice for obtaining coal, the world’s leading energy source. Surface mining removes vegetation, soil, and rocks to extract resources. In Indonesia, the world’s fifth largest coal producer, coal mining companies are required to rehabilitate mined sites. Companies typically plant exotic legume tree species because they quickly achieve canopy closure, limit invasive weeds, improve soil nitrogen, and create a light environment that helps with the recruitment of woody plants. This article looks to see whether natural forest succession occurs under leguminous plantations at rehabilitated coal mines in East Kalimantan, Indonesia. 

Carbon-focused conservation may fail to protect the most biodiverse tropical forests

Introduction

The authors examine the relationship between carbon and biodiversity at the landscape-level across four gradients of disturbances and offer insight on optimizing carbon conservation projects with biodiversity conservation.

Potential for low-cost carbon removal through tropical reforestation

background

The UNFCCC COP21 (UN Framework Convention on Climate Change Conference of the Parties) created the Paris Agreement in 2015, which pledges to “limit global warming to well below 2, preferably 1.5 °C.” For this to happen, we must both reduce how much carbon dioxide (CO2) that is released and find ways to capture CO2 that is already in the atmosphere. This study explores two ways this might happen using Nature-based Solutions: tree planting in the form of reforestation and afforestation, and the prevention of deforestation.
