Emerging Technologies and Sustainable Mining Practices in Tanzania: Innovations, Challenges, and Strategic Pathways

Abstract

The mining sector is a fundamental engine of economic development in Tanzania; however, it remains one of the most environmentally and socially intensive industries. While global discourse emphasizes the integration of emerging technologies and low-impact practices to align mining with the Sustainable Development Goals (SDGs), a significant knowledge gap exists regarding the localized adoption and impact of these innovations in Tanzania. Grounded in the Theory of Technological Innovation, Sustainable Development Theory, and Stakeholder Theory, this study investigates the role of emerging technologies and low-impact methods in enhancing operational efficiency and environmental sustainability in Tanzanian mining operations. Employing a mixed-methods research design, the study collected data from 100 diverse mining stakeholders including government officials, mining employees, community members, and technical experts through structured surveys and key informant interviews (KIIs). Quantitative data were analyzed using descriptive statistics, while qualitative data underwent thematic analysis. Findings reveal a strong stakeholder consensus (Mean scores > 4.0) that automation, real-time safety monitoring, and renewable energy integration significantly improve operational efficiency, reduce downtime, and enhance worker safety. Similarly, low-impact practices such as controlled blasting, mechanized excavation, and water recycling are proven to lower operational costs and mitigate environmental footprints. Despite these recognized benefits, the widespread adoption of sustainable practices is severely constrained by financial limitations (75%), limited technical capacity (72%), regulatory bottlenecks (70%), and restricted access to modern technology (68%). Qualitative insights confirm that without government-backed incentives and targeted capacity building, these technologies remain underutilized, particularly among artisanal and small-scale miners. The study concludes that while technological innovations offer a viable pathway for sustainable mining, realizing their full potential requires strategic interventions, including financial support mechanisms, comprehensive training programs, and the harmonization of regulatory frameworks.
