Evaluation of the Efficiency of Implementation of the Sustainable Development Program at Nickel-Cobalt Ore Mining Enterprises

The environmental crisis and the accelerated depletion of natural resources require strategies that balance economic growth and environmental protection in accordance with the principles of sustainable development. In this context, the mining industry, despite playing an important role in economic development, has significant negative impacts. The application of sustainable practices helps to mitigate these impacts. This study evaluates the effectiveness of rehabilitation measures applied in the abandoned mine of Punta Gorda, Cuba, using an integrated system of socio-environmental and economic indicators. The methodology, based on a procedure for socio-environmental and economic management in mine rehabilitation, comprises six stages and fourteen steps, including the valuation of ecosystem goods and services, economic valuation, and monitoring of rehabilitation results. Key results show a 5.95% improvement in economic efficiency in 2023, partial recovery of the ecosystem after rehabilitation, and improved health of mine workers. The study emphasizes the importance of multidimensional assessment tools to align mine rehabilitation with the Sustainable Development Goals (SDGs), particularly SDG 11, and highlights the role of corporate social responsibility in improving the well-being of the mining community. The proposed framework provides a replicable model for sustainable mine rehabilitation, emphasizing the integration of economic, social, and environmental indicators.
