The case links aquifers, utility planning and everyday household access. How can a utility move from groundwater to surface water without leaving some neighbourhoods short of supply in the meantime? Source-water quality, plant delivery times, network losses, tariffs and the needs of households that rely on shared or informal connections must be examined together.

The City's 2019 Water Strategy, as described by UCT News, commits to alternative sources (desalination, reuse, groundwater) adding more than 300 million litres per day over ten years and expects the supply share from storage dams to fall to about 75% by 2040 from the current 95%. In a City statement of 2 January 2026 the City set a summer usage target of less than 975 million litres per day and reported average use of 1 025 MLD on 31 December 2025, with dams at 70.5%; the City's weekly report for 7 October 2026 shows total storage at 75.4%. The case links water supply, wastewater treatment and reuse, treated-effluent networks and municipal procurement and finance. How do voluntary summer usage targets, dam storage and the timing of new-water projects interact in Cape Town's water supply planning? Rainfall and dam storage in the year concerned, the status of restrictions and tariffs, the pace of the New Water Programme projects, and the period and basis of each consumption figure would need to be examined together before any lesson could transfer elsewhere.

NParks reported in April 2023 that over 500,000 trees had been planted since March 2020 and said it expected to reach one million by end 2027.

How do the Green Plan's separate 2030 targets for trees, transport, buildings and waste interact in the same land-scarce city, and which published indicators show this?

For transport, SMG's January 2026 release reports more than 17 million cumulative Climate Card recharge transactions and average daily usage of about 720,000 people as of November 2025; the card was announced in 2023 at 65,000 won a month for subway, bus and public bike. For flooding, SMG's 2023 page plans deep underground rainwater tunnels at three sites and a rise in design rainfall capacity from 95 mm to 100-110 mm per hour.

How do Seoul's emissions target, its transport pricing scheme and its flood-drainage investments interact in budgets, timelines and measured outcomes?

Before any lesson transfers, the baseline of each measure (street grid, vehicle fleet, building stock, climate and the opening hours of public facilities) and the way outcomes were modelled or measured should be examined together. Political and legal changes to the plans over time, and who is counted as covered, also need to be compared.
