South Africa 2026

Afrika Selatan

South Africa enters 2027 as a middle-income economy of 63.5 million people whose water and electricity sistem are under strain, whose food supply is currently ample, and whose floods have become deadly at provincial scale. Greenhouse-gas emissions were about 478 Mt CO₂e in 2022 excluding land use, with energy supplying 78% of the total.

01 · Readings

South Africa in six readings.

Six readings that frame the South Africa baseline, and the eight questions this edition answers, each with its status and source.

  • 63.5millionpopulation, mid-2026 [1]
  • 10.7%aged 60 or over, 2026 [1]

02 · Sectors

Six sectors, one hexagon.

Water first, then Energy, Infrastructure, Food, Health and Biodiversity. Each count is the findings of this edition in that sector: coverage of the evidence, never a score. Infrastructure is not assessed: the edition holds no Infrastructure finding and its coupling matrix does not assess it.

03 · Hazard exposure

The hazards this edition reads.

The edition’s own risk objects, in its order, each read across driver, exposure, vulnerability, capacity, cascade and horizon. The hexagon marks the sectors the cascade reaches; the domain beside each is an editorial reading of its hazard words.

Scenario · SCN-ZAF-PWR-01

Power shortfall and wastewater stress in a dense province

Under this scenario, results describe a conditional season under stated assumptions. It is not a forecast, and no intervention described here has been carried out.

04 · Couplings

How the sectors carry risk into each other.

The South Africa matrix types the twenty couplings between the five core sistem. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.
