This week in SA reform — Infrastructure Delivery Management System in committee

The Infrastructure Delivery Management System — mandated since 2015, adopted by fewer than 40% of departments — was in committee this week, with 22 linked sittings. South Africa returns R5–8bn of capital budgets to Treasury each year because departments cannot plan and execute, not because money is scarce. Also this week: water boards and the NWRIA, and a 567-paper expansion of the research corpus.

Climate shocks, labour market dynamics and inequality in South Africa: Evidence from administrative data tax

Sefa Awaworyi Churchill, Yohannes Kefale Mogess, Yuvana Jaichand · UNU-WIDER · 2026-01-01

Temperature shocks are already eroding South African earnings. Using satellite temperature data merged with administrative tax records from 2009 to 2022, a one-standard-deviation rise in average temperature is associated with a 1 per cent fall in earnings and a 1.3 per cent fall in total income. Income inequality, by contrast, shows no statistically significant response, suggesting the losses are broadly distributed across the earnings distribution rather than concentrated among lower earners in the tax net. Projections drawing on CMIP6 climate models indicate that, absent mitigation and adaptation, income could be 5 per cent lower by 2100 relative to a scenario with widespread renewable energy uptake and emissions reduction. For South African reform, the findings tie climate policy directly to fiscal and labour market outcomes, strengthening the case for embedding adaptation measures and a just energy transition within broader economic planning.

Detecting profit shifting in administrative data: A South African perspective

Matthew Amalitinga Abagna, Ronald B. Davies, Miroslav Palanský · UNU-WIDER · 2026-01-01

Fewer than 1% of multinational enterprises operating in South Africa display persistent signs of profit shifting, yet this narrow group accounts for a disproportionate share of the corporate tax revenue at risk. Using linked administrative tax and customs records, Abagna, Davies and Palanský flag firms that report profits persistently below their industry average and simultaneously exhibit at least one additional warning sign — elevated related-party debt, unusual intra-group service payments, or trade routed through tax haven jurisdictions. The layered filter isolates a small population of high-risk firms without relying on transfer pricing documentation or bespoke data collection, drawing instead on records SARS already holds. For South African reform, the method offers a low-cost, replicable basis for audit prioritisation and strengthens the empirical case for tightening rules on interest deductibility, service fees, and haven-linked trade as part of domestic resource mobilisation.

Idea of the week

South Africa returns R5–8 billion in capital budgets to Treasury each year not because the money is scarce but because departments cannot plan and execute projects to spend it. The Infrastructure Delivery Management System has been policy-mandated since 2015 and adopted by fewer than 40% of national and provincial departments. The binding constraint is government capacity: DPWI's vacancy rate for engineers and project managers exceeds 35%, and the standardised framework Treasury and DPWI built sits unused while roads crack and clinics leak. Fixing execution is fiscally neutral, which is either the good news or a quiet indictment, depending on the reader.

The professional project management mandate would make IDMS compulsory for projects above R30 million, deploy registered PMs through the PMTE, publish live dashboards to oversight committees, and use CIDB accreditation of implementing agents as the enforcement lever. Consequence management for officials who bypass IDMS controls is the piece most likely to be diluted, and the piece that matters most; standardised frameworks have a long South African history of being observed decoratively.

Activity this week — 22 new links to meetings across Public Works and Infrastructure and Water and Sanitation — suggests the diagnosis is landing in more than one committee room, though the idea has been raised formally only once. Watch whether DPWI's next quarterly report to the Public Works committee moves from lamenting under-expenditure to naming an IDMS compliance rate, and whether CIDB signals it will expand its PM accreditation pipeline before the medium-term budget.

Constraint check-in

As of August 2026, government capacity remains the binding constraint on delivery, and the week's movement reinforces rather than relieves it. Only the National Water Resources Infrastructure Agency has crossed into partial implementation; the balance — the Infrastructure Delivery Management System's professional project management mandate, ring-fenced building maintenance budgets, and the Equitable Share Formula review — sits at the proposal stage, each rated feasibility 3. The pattern is familiar: diagnosis is converging faster than institutional build-out, and the Finance Select Committee's engagement with the fiscal framework review confirms that reprioritisation is now being contemplated without a corresponding upgrade in administrative throughput.

Watch the Portfolio Committee on Water and Sanitation's oversight of NWRIA's transitional arrangements over the next quarter. Whether the agency inherits functioning project pipelines and technical staff from DWS — or is stood up as a shell dependent on the same constrained departmental capacity — will indicate whether the "agencification" route can genuinely substitute for line-department reform, or merely relocate the bottleneck.
