The rising demand for critical metals presents a major economic opportunity mineral-rich countries. For sustainable transition to low-carbon future, it is essential minimise impacts of mineral resource development the environment, ecosystems, and societies these nations. Although there has been considerable progress in social aspects mining sector, environmental metrics are not showing comparable improvement. Philippines exemplifies this challenge as country that aims conserve its exceptional biodiversity maximise ecosystem services while expanding activities growth, geographical setting with high potential vulnerability natural hazards climate change. Similar many areas, baselines mostly non-existent, compounded by legacy despite an established policy framework. We review issues associated large- small-scale identify underlying research challenges opportunities Philippines. Potential pathways include (i) innovative approaches catchment scale characterisation identification contaminant sources; (ii) quantifying predicting transport; (iii) deployment flexible monitoring devices larger-scale water quality programmes; (iv) tailings dam management; (v) assessment metal recovery ores tailings. By integrating geomorphological tools geochemical data, well 2D/3D numerical modelling techniques, becomes possible predict understand behaviour fate contaminants across different spatial temporal scales. cost-effective protocols can help overcome logistical wider range hydrological conditions. Advanced applications remote sensing, combined machine learning, geophysical systems provide new detect footprints observe change dams more effectively. mine wastes be further minimised exploring technologies such use metal-accumulating native plant species environmentally safe solvents reprocess modern Insights from will enable realisation through incorporation findings into existing future governmental small- large-scale practice. This lead society, particularly nations positioned benefit development.

The B1 tailings dam of Córrego do Feijão iron-ore mine owned by Vale, S.A. company collapsed in 25 January 2019 releasing to the Ferro-Carvão stream watershed (32.6 km2) as much 11.7 Mm3 waste. A major share (8.9 Mm3) has been deposited along channel and margins forming a 2.7 km2 patch. main purpose this study was question whether deposit impacted local water cycle how. Using Soil Water Assessment Tool (SWAT) hydrologic model, balance components 36 response units (HRU) were calculated for pre- (S1) post- (S2) rupture scenarios represented appropriate soil, land use cover. results revealed an increase evapotranspiration from S1 S2, related sudden removal vegetation valley replacement with blanket mud, which raised exposure Earth's surface sunlight hence soil evaporation. For 11 HRU (10.3 located around deposit, decrease lateral flow observed, accompanied percolation slight groundwater flow. In case, changes observed between S2 reflected barrier effect imposed flows tailings, shifted towards vertical direction (percolation). Thus, followed easier route until reaching shallow aquifer being converted into As per modelling outcomes, impacts are relevant because they affected 1/3 watershed, claim complete tailings.

Tailings ponds, essential components of mining operations worldwide, present considerable potential hazards downstream in the event tailings dam failures. In recent years, instances failures, carrying environmental safety hazards, have occasionally occurred on a global scale due to limited technical approaches available for supervision ponds. this study, an innovative WebGIS-based unmanned aerial vehicle oblique photography (UAVOP) method was developed analyze storage capacity change and failure risk Its applicability then validated by deploying it at pond Yunfu City, Guangdong Province, China. The results showed that outcomes two phases real-scene 3D images met specified accuracy requirements with RSME 0.147–0.188 m plane 0.198–0.201 along elevation. capacities phase I II ponds were measured 204,798.63 m3 148,291.27 m3, respectively, 56,031.51 m3. Moreover, minimum flood control widths, free heights, slope ratios determined comply requirements, indicating low pond. This pilot case study demonstrated performance UAVOP evaluating It not only enhanced efficiency dynamic but also offered valuable references globally analogous research endeavors.
