“…As a result of the extended age of stockpiles with their high depth (beyond 6m), the use of heavy equipment in the stockpiling process and the resultant nutrient volatilization, leaching, mineral compaction and sedimentation, there is a concomitant degradation of soil physicochemical properties including aeration, cation exchange capacity, gravimetric moisture content, soil carbon, nitrogen and phosphates among others. Again, the loss of vegetational biomass associated with the stockpiling process truncates the soil carbon cycle leading to loss of soil flora and fauna and soil biodiversity in general (Kuan et al, 2020).…”

Extractive resources, particularly minerals, soil and timber, have historically supplied the infrastructural, technological, energy and many other goods and services consumers enjoy. However, the global value chains for these high-valued commodities have been criticized as being abusive of economic, sociocultural and environmental rights of resource-rich communities and nations. Paradoxically, it has been found that countries with abundant natural resources such as gold, oil, bauxite, etc. tend to have less economic growth, poor democracy, and worse development outcomes than countries with fewer natural resources due to poor governance, limited accountability, poor transparency and weak technical capacity (Adams et al., 2018). The questions that development practitioners and scholars often ask has been how Africa's natural resources can be effectively governed to best serve the wellbeing and needs of Africans including staying within ecological limits and improving environmental quality. To this end the concepts of natural resource governance, sustainable mining and ecological governance among others are gaining popularity in discourses within the environment and natural resource space as activists and scholars question the role of extractive resources on human wellbeing and environmental sustainability. Questions such as what should inform mineral resource governance policy to guarantee sustainability?, how can existing policies be improved to facilitate the entrenchment and achievement of intergenerational equity for resource-rich countries?, what variables, themes and concepts should be prioritized or managed to achieve a balance between human wellbeing and environmental sustainability?, what role

“…Globally, most of the bauxite mining projects which are being executed in the tropical regions pose a significant threat to undisturbed forests and biodiversity hotspots (Mindszenty, 2016;Murguía et al, 2016). China and Malaysia have relevant experience in dealing with bauxite mining operations and environmental mitigation after mines are closed (Thorpe & Watve, 2015;Kuan et al, 2020).…”

given that a spatially driven design can provide much needed knowledge of the restoration/reclamation plan for Bauxite Mine Lands. Ecologically sound designs are a catalyst for devising mechanisms which can (help to) reduce environmental impacts. These designs can also help to boost the velocity at which ecological processes operate, in order to increase the resilience of ecosystems and the connectivity between forest patches and continuous pristine forests.

Phosphorus adsorption in a degraded soil under forestry recovery after bauxite mining in Paragominas, eastern Amazon, Brazil

The availability and retention of phosphorus (P) in soils under recovery process after mining operations play an important role in the management of this nutrient. The objective of this study was to evaluate the P adsorption in a reconstituted soil as a function of two forest recovery processes after bauxite mining. We evaluated three systems: native forest (FOR), planting of forest seedlings after bauxite mining (TPL), and natural regeneration of vegetation after bauxite mining (NRV). In each system, eight sampling plots were deployed. In each plot, we collected litter and soil samples. The soil samples were collected at depths of 0–5, 5–10, 10–20, and 20–40 cm, for soil chemical analysis and adjustment of P adsorption isotherms. We also performed an inventory of the tree vegetation to obtain basal area (G) and species diversity (H′). Forest was significantly superior with respect to most soil fertility, litter, and vegetation attributes, followed by natural regeneration and planting. In general, the adsorption curves and maximum phosphorus adsorption capacity (MPAC) in soil followed the order planting > natural regeneration > forest. We observed a negative relationship between phosphorus adsorption and soil organic matter, potential acidity, and available phosphorus. This result highlights the importance of biomass conservation and maintenance to ensure phosphorus availability in reclamation practices. Furthermore, such results indicate that both soil cover and plant species diversity should be considered when selecting species to improve P availability for reclamation of mined areas.
