Karu, V 2025, 'A mine closure case study: Aidu oil shale open cast as a centre for future rowing champions after closure', in S Knutsson, AB Fourie & M Tibbett (eds), Mine Closure 2025: Proceedings of the 18th International Conference on Mine Closure, Australian Centre for Geomechanics, Perth, pp. 1-9, https://doi.org/10.36487/ACG_repo/2515_38 (https://papers.acg.uwa.edu.au/p/2515_38_Karu/) Abstract: The Aidu oil shale open cast mine in Estonia has transformed remarkably from an industrial extraction site into a world-class rowing channel. After closing the mining activities, extensive rehabilitation efforts reshaped the post-mining landscape into a sustainable water sports facility. The former mine site’s unique geological and hydrological conditions enabled the creation of a long, deep, and calm water body, ideal for competitive rowing and recreational water activities. This case study explores the environmental, engineering, and socioeconomic aspects of repurposing Aidu as a rowing venue, highlighting the challenges and opportunities of post-mining land use. The project demonstrates how industrial landscapes can be revitalised for ecological restoration and community development, contributing to regional tourism and economic diversification. Aidu’s transformation sets a precedent for sustainable post-mining rehabilitation, balancing environmental recovery with new public and sports infrastructure.
