Uranium Extension or Tourism Corridor: Water as the Deciding Constraint
A regional planning committee in the Namibian interior must advise on two competing applications for the same 1,200 hectares of semi-desert. The Kalahari Uranium Project wants a nine-year mine: 700 jobs in two years of construction, 450 operational jobs, a wage bill of N$480 million a year, of which the company estimates 85% is spent locally, plus corporate tax and a royalty. It needs 4.5 million cubic metres of water a year from an aquifer whose measured recharge is about 6 million cubic metres a year and from which farms, the town of 4,200 people and a lodge already abstract 4.2 million. It would employ mostly skilled workers from outside the region. The alternative is a conservancy-linked tourism corridor: 120 beds, about 90 permanent jobs, a wage bill of N$34 million a year and water use of 0.35 million cubic metres. Local unemployment is 34% and only 28% of adults have completed Grade 12. Both applications say they will fund a clinic.
1. Evaluate the two options and recommend one, showing your reasoning with the figures.

Water first, because it is the binding constraint. Recharge is about 6.0 million m³/yr; existing abstraction is 4.2 million, leaving a safe headroom of roughly 1.8 million. The mine's 4.5 million is about 2.5 times that headroom and would take total abstraction to 8.7 million - around 145% of recharge. That is mining the aquifer: water levels fall, farm boreholes and the town supply fail, and the mine itself may not have water in year nine. The tourism corridor's 0.35 million fits inside the headroom with about 1.45 million to spare, though it still needs a licence and metering.
Jobs and money: the mine dwarfs tourism - 450 operational jobs versus 90, and a wage bill of N$480 million versus N$34 million, with an 85% local spend giving a large multiplier through local suppliers. Tourism's smaller wage bill is spread more widely and is more resilient; mine jobs end abruptly at closure.
Skills fit: only 28% of adults completed Grade 12, so most of the 450 operational posts would be filled by outsiders unless the company funds a real training and local-procurement agreement. Construction's 700 jobs are temporary.
Recommendation: refuse the mine at the requested volume. If the region wants mining, it must be conditional on a much smaller allocation (no more than the 1.8 million m³ headroom, shared), an independent recharge study, borehole monitoring, and a funded closure plan. Otherwise approve the tourism corridor and treat water as the priority allocation.
2. The committee chair argues that jobs matter more than water because the mine creates five times as many posts. How would you answer, and what evidence would you ask the mine to supply?
Read the worked answer
Answering the chair: five times as many jobs only matters if the jobs last and if the region survives their demands. Two points. First, job numbers should be compared as job-years: 450 posts for nine years ≈ 4,050 job-years, and 90 posts for 25+ years ≈ 2,250 job-years - the gap is real but much smaller than 5:1. Second, the mine's water use damages the livelihood of every farm and the town supply, which is itself employment; destroying the aquifer to create 450 jobs can produce a net loss of livelihoods and will not be forgiven at closure.
Evidence to demand:
- A hydrogeological model, independently reviewed, showing drawdown at each neighbouring borehole over nine years, not a single regional average.
- Metered abstraction records and a commitment to a hard annual cap with published compliance.
- A local-content plan with named posts, a training budget and a target share of Grade 12 completers in the workforce.
- A closure and rehabilitation bond, funded progressively, not promised at the end.
- Water-saving evidence: dry or low-water ore processing, recycling rates, and whether saline or alternative sources were considered.
- An economic model of the 85% local-spend claim, showing how much is wages spent in the region versus procurement from outside.
With those, the committee can negotiate a capped allocation. Without them, the 4.5 million m³ figure is an unsupported assumption and the 5:1 jobs claim is being used to avoid the real question.
