Acid Mine Drainage from Gold Mining in South Africa: Remediation, Reuse, and Resource RecoveryBACKGROUND:Acid Mine Drainage (AMD) is a persistent issue in South Africa, stemming from both active and defunct mines. It generates from waste materials, leading to severe environmental consequences such as water pollution and ecosystem disruption. The acidic and metal-rich nature of AMD poses significant environmental hazards if not properly managed. Open access copy available |
The principles of natural climate solutionsBACKGROUND:Natural Climate Solutions (NCS) were consolidated as a holistic concept in 2017, leveraging human interventions in land management to mitigate climate change by adapting existing conservation knowledge for climate action. Over the past six years, the implementation of NCS has seen a rapid increase in attention, as indicated by a significant rise in social media discussions and funding commitments, though these efforts still fall short of the levels required to meet global climate mitigation goals. The authors use a comprehensive review of scientific literature and best practices to distill foundational and operational Open access copy available |

Climate Risk ManagementBACKGROUND:Worldwide efforts are underway to devise and apply strategies to manage these risks effectively. Key challenges in climate risk management include the integration of necessary scientific disciplines, articulating stakeholder values and objectives, and quantifying pivotal uncertainties and trade-offs, all of which are vital for crafting effective management strategies. The paper addresses the intensification of global climate risks driven by accelerating climate change. The authors review these challenges based on existing literature to identify potential avenues to overcome them. Open access copy available |
Advances and shortfalls in applying best practices to global tree‐growing effortsBACKGROUND:Over the past three decades, there has been a rapid increase in the number of organizations engaged in tree planting to meet international targets exceeding a trillion trees. These initiatives aim to sequester carbon, conserve biodiversity, enhance water quality, and reduce social inequity. Despite these goals, frequent failures and unintended ecological and social impacts have led to the creation of numerous best practice guidelines for reforestation. Open access copy available |
Livelihoods, Forests, and Conservation in Developing Countries: An OverviewBACKGROUND:Poverty is a huge challenge, with 2.8 billion of the world’s 6 billion people living on less than $2 a day. The paper highlights the alarming extent of poverty in developing countries and addresses the rapid deforestation, which compromises ecological integrity and exacerbates social inequities. The authors focus on exploring whether poverty alleviation and forest conservation can be aligned as complementary rather than conflicting objectives. Available with subscription or purchase |
Forest concessions in the Maya Biosphere Reserve, Guatemala: A decade laterBACKGROUND:Over the past few decades, there has been a significant shift in conservation strategies from traditional command-and-control approaches to more inclusive, community-focused philosophies. This transition was driven by the recognition of the failures of strict protectionism, which often led to diminished ecological and institutional resilience. Simultaneously, the recognition of rural communities as both impacted by and impactful within natural systems has grown, advocating for incentive-based, participatory strategies to address human-environment conflicts effectively.

Nitrogen Fixing Trees for Animal Production on Acid SoilsBackgroundNitrogen-fixing trees play a crucial role in improving pasture and livestock systems on acid soils, which are prevalent in tropical regions. Acid soils often challenge agricultural productivity due to low fertility and high aluminum toxicity. Nitrogen-fixing trees, such as Erythrina poeppigiana, Cratylia argentea, and Alnus acuminata, enhance soil chemistry and fertility by adding nitrogen through organic matter and improving physical soil properties like porosity and bulk density. They are integrated into silvopastoral systems, where trees and shrubs coexist with pastures, offering multiple benefits such as soil stabilization, increased forage quality, and diversified farm outputs.
