Other

The "Other" bucket in a growth diagnostics exercise is the residual where a constraint is visible and costly but does not fit cleanly into the canonical HRV branches of finance, returns to capital, or appropriability. In South Africa's case, the binding character of several such items flows from a specific institutional pathology: the state has inherited large stocks of legacy liabilities — environmental, infrastructural, and fiscal — whose unresolved status imposes a drag on private investment decisions well beyond their nominal balance-sheet value. Derelict and ownerless mines are the paradigm case. The Department of Mineral Resources and Energy's own inventory records well over 6,000 such sites, with rehabilitation cost estimates by the Auditor-General and the Council for Geoscience ranging into the tens of billions of rand. Because liability for adjacent land, water, and community health is legally ambiguous, the overhang deters both greenfield mining investment and downstream land-use conversion — a textbook case of a constraint that is binding through uncertainty rather than through price.

The single idea currently logged here, the Derelict and Ownerless Mines Rehabilitation Fund, proposes a ring-fenced financing vehicle to absorb and sequence remediation of orphaned sites, presumably capitalised through a blend of fiscal allocation, industry levy, and possibly concessional climate finance given the methane and acid-mine-drainage co-benefits. Its modest 2/5 growth-impact rating is honest: rehabilitation is not a productivity lever in itself, but it clarifies property rights over large tracts of Mpumalanga, Gauteng, and Free State land, and it removes a contingent liability that quietly shadows the mining cadastre reform agenda. The common thread — even in a database of one — is institutional: the bottleneck is not money so much as a credible custodian.

Watch three things over the next year: whether Treasury and the DMRE agree on a governance shell for such a fund, whether the forthcoming amendments to the Mineral and Petroleum Resources Development Act clarify successor liability, and whether any pilot rehabilitation site moves from gazette to spade.
