“…This pit lake became a new tourism and sightseeing area near Banjarmasin, the capital of South Kalimantan, probably due to the lack of tourism areas for residents. This pit lake is about 30 m deep and has a very acidic pH, around 3.75, which is certainly not suitable for long-term daily use [197]. This shows that more in-depth and serious attention is needed to study the characteristics of pit Planting multi-species at post-coal-mining lands accelerates the succession stage, increases plant biodiversity [129], and serves as a food source for various wild animals that support the diversity of the fauna [198].…”

Tropical forests are among the most diverse ecosystems in the world, completed by huge biodiversity. An expansion in natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices are needed as an effort to reclaim their function. This paper summarizes the existing practice of coal mining, covering the regulatory aspects and their reclamation obligations, the practices of coal mining from various sites with different land characteristics, and the reclamation efforts of the post-mining landscapes in Indonesia. The regulations issued accommodate the difference between mining land inside the forest area and outside the forest area, especially in the aspect of the permit authority and in evaluating the success rate of reclamation. In coal-mining practices, this paper describes starting from land clearing activities and followed by storing soil layers and overburden materials. In this step, proper handling of potentially acid-forming materials is crucial to prevent acid mine drainage. At the reclamation stage, this paper sequentially presents research results and the field applications in rearranging the overburden and soil materials, controlling acid mine drainage and erosion, and managing the drainage system, settling ponds, and pit lakes. Many efforts to reclaim post-coal-mining lands and their success rate have been reported and highlighted. Several success stories describe that post-coal-mining lands can be returned to forests that provide ecosystem services and goods. A set of science-based best management practices for post-coal-mine reforestation is needed to develop to promote the success of forest reclamation and restoration in post-coal-mining lands through the planting of high-value hardwood trees, increasing trees’ survival rates and growth, and accelerating the establishment of forest habitat through the application of proper tree planting technique. The monitoring and evaluation aspect is also crucial, as corrective action may be taken considering the different success rates for different site characteristics.

Pit lakes may present significant risks to ecological and human receiving environments but can also provide beneficial end use opportunities. The understanding of many processes that influence the magnitude of these risks and opportunities remains limited, and even where our understanding is adequate, the application of that knowledge is not consistently applied. From initial planning to long-term closure, regulation and corporate management of pit lake closure can be improved to realise more sustainable pit lake legacies. In this two-part manuscript, we recommend focus areas for future research by academics (Part 1), and strategies to structurally improve the practice of pit lake closure for mining industry regulators, corporate sustainability officers, global practice leads, and site mine closure planners (Part 2). Here we identify barriers that often limit the understanding of pit lake processes and closure practices and suggest ways that corporate leaders, closure practitioners, and regulators can improve pit lake management. Recommended corporate changes include: conducting risk assessments at an early planning stage; funding pit lake research and trials; allowing data sharing and case study publication; avoiding the simplifying assumption of a fully mixed pit lake when making predictions; integrating climate change into pit lake predictions; improving the quality of technical reporting; generating industry guidance for pit lake rehabilitation; maximizing opportunities for subaqueous, in-pit disposal of mine wastes; creating a positive legacy through beneficial uses of pit lakes; and verifying predictions using long-term monitoring. Recommended regulatory advancements include: raising expectations of corporate pit lake closure planning and execution; acknowledging good pit lake closure examples; balancing the need to simulate long closure periods with expectations of model reliability; considering the value of pit lakes as future water resources during permitting; and requiring closure costing and bonding commensurate to closure risk.
