What Kenya Can Learn from Kwale Before the Next Mine Opens

By Aron Kecha, Senior Sustainability Researcher

Kenya is entering a new phase of mineral development. Interest is growing in copper, niobium, rare earths and other strategic minerals, and with it comes a question that is easy to postpone: what will a mine leave behind once the minerals are gone?

Kwale gives us a real case to think with. Base Titanium began mining there in 2013 and stopped at the end of 2024, once the ore reserve was depleted (Okello & Vickers, 2024) [1]. It was Kenya’s largest mine, and the site is now in decommissioning, rehabilitation and post-mining land-use planning. Because of its size, the way its closure unfolds will be watched closely, and it is worth being careful about what we can and can’t yet say about it.

Kwale is a useful case for two reasons. It shows what early planning, engineering and regulatory oversight can achieve, and it shows where the evidence is still thin and where some people still have unanswered questions.

Planning for closure started early

NEMA’s National Guideline on Mine Site Decommissioning and Rehabilitation says closure planning should begin at the design stage and continue through the life of the mine, so that costly clean-up isn’t left until the end [2]. At Kwale, the company says it worked this way, with closure planning beginning before mining did and land being rehabilitated in phases while operations continued [11]. According to evidence put before the court in the case described below, NEMA approved a comprehensive closure and decommissioning plan in 2024 [8].

The technical approach is described in a paper by Base Titanium staff: landforms designed for stability, topsoil management, tailings co-disposal, wetland creation and planting of indigenous species [1]. It is a useful account of the methods, but because the authors work for the operator, it is best read as the company’s own description of its work.

Most of the progress figures so far come from government and company sources. The Mining Principal Secretary said in 2025 that about 55 per cent of the mined land had been restored [12]. In 2026, NEMA’s Coast regional officer commended the company for complying with regulations and restoring land, and a representative of the Kwale Mining Alliance referred to independent assessments finding restored areas close to their natural condition [16]. The Kenya News Agency reported in May 2026 that the rehabilitation was gaining recognition as a model for restoration in Kenya [3].

These are encouraging signals. They are also statements rather than data, and the assessments mentioned aren’t cited or linked in the reports, so readers can’t check them for themselves. Publishing the underlying monitoring results would do more for public confidence than any number of endorsements.

Where the picture is still unsettled

Residents of Kinondo went to the Environment and Land Court in early 2026, alleging environmental degradation, and obtained orders on 26 February that halted dismantling, decommissioning and land disturbance at the site [13][8]. At the start of April the court varied those orders so that work could continue under conditions. The two reports I have seen describe the ruling a little differently. Business Daily says decommissioning must proceed in line with the approved closure plan, the existing EIA licences and NEMA’s directions [8]. The Standard quotes the judge permitting “limited, safety-critical decommissioning activities” alongside disclosure and an independent audit [13]. Either way, the main petition goes on to a full hearing, so the questions the residents raised have not yet been decided [8].

Separately, the Supreme Court has directed that a pollution case against the company proceed before the Environment and Land Court [14]. That decision concerned jurisdiction, and the allegations themselves are still to be determined. The company’s position, as reported, is that it carried out environmental impact assessments, obtained NEMA’s approvals and complied with its licence conditions [14].

Community voices matter here too. At a 2026 meeting reported by the Kenya News Agency, residents of Fingirika, Nguluku and Mchanga Mweupe called for stronger representation, fairer access to post-mining benefits and productive use of the rehabilitated land, and one resident raised concerns about displacement and compensation [17]. These echo earlier academic work on conflicts over land, compensation and corporate social responsibility around the project [7].

On the future of the land, the Mining Cabinet Secretary launched an Advisory Report on Post-Mining Land Use for the project in Kwale on 10 January 2026, intended to guide land allocation and investment as the county moves into a post-mining economy [15][9]. It’s early days, and how well it reflects community priorities will become clearer as it is put into practice.

A stronger rulebook, still to be tested

Kenya’s rules have also been moving. The NEMA guideline covers closure obligations, engagement with project-affected persons, post-closure audits and monitoring, and financial provision [2]. A guideline is guidance, so what matters is how it is built into licence conditions in practice.

On the financial side, the Environmental Management and Co-ordination (Deposit Bonds) (No. 2) Regulations, 2025 (Legal Notice 67 of 2025) were published in March 2025, replacing an earlier set issued the month before. They cover mining and quarrying, require a Deposit Bond Assessment Report that NEMA reviews for adequacy and reliability, allow the bond to be reassessed, and list factors for inspection such as public safety, ecological recovery and stakeholder involvement [6]. Before that, a 2022 study of deposit-bond use in Kenya’s titanium mining projects had pointed to weaknesses in the framework as it then stood [5]. The new regulations look like a considerable step forward, though it is too early to say how they will work on a real closure. NEMA and the State Department of Mining have also published draft guidelines on mining deposit bonds and on participatory environmental monitoring for public comment [10].

Three practical questions will probably decide whether the framework delivers. Is the bond large enough to cover the credible cost of rehabilitation? Can the money be reached quickly if an operator defaults or becomes insolvent? And is release of the bond tied to demonstrated results, such as ecological recovery, stability, safety and an agreed after-use, rather than to promises? The regulations point in the right direction on the last of these [6]. The first two will depend on how assessments and enforcement work out.

Verification and long-term responsibility

Several headline claims about Kwale, such as the area rehabilitated or the share of process water recycled, come from the company, government agencies or both. That doesn’t make them wrong, but they would be easier to trust if they were published, independently checked and based on methods others could reproduce. A single, independently verified water balance for the life of the mine is one example of what would help.

Some risks also don’t end with the last shipment of ore. Tailings facilities, groundwater, drainage and rehabilitated ecosystems may need monitoring for years. The company has pledged continued maintenance of the rehabilitated areas [16], and the NEMA guideline expects post-closure audits and clear monitoring responsibilities [2]. Its idea of “unacceptable liability”, meaning a closure that leaves regulators, communities or landowners with a greater ongoing management burden than existed before mining [2], is a good test to apply to every closure decision.

What would help

Kenya now has much of the policy architecture it needs for responsible mine closure, so the practical focus is on implementation. A few steps that would help:

1. Treat closure planning as part of the licensing decision from the outset, and update it through the life of the mine [2].
2. Keep financial assurance current, with bonds that reflect independently assessed closure costs and are reviewed as the mine changes [6].
3. Link rehabilitation to measurable licence conditions, such as annual targets for landform stability, vegetation, biodiversity and agreed after-use.
4. Verify key claims independently, including water, soil, biodiversity, tailings stability and ecological recovery, and publish the results.
5. Bring communities into monitoring, with access to the results; the participatory monitoring guidelines now in draft [10] could be a natural vehicle.
6. Name who monitors and who pays for tailings, groundwater and drainage after the operator leaves.
7. Document the Kwale experience, including costs, successes, shortcomings and unresolved issues, so the next round of licensing can learn from it.

Judging Kwale fairly

Kwale will probably be judged over years rather than months. The court case is still open, the land-use plan is only beginning to be implemented, and the new bond regulations haven’t yet been tested on a closing mine. What Kenya can do now is make sure that, whatever the eventual verdict on Kwale, the evidence exists to reach one: published monitoring data, independent checks, and communities who can see and question both.

The aim is simple enough. When the minerals are gone, neither the public nor the environment should be left carrying costs the mine was meant to cover.
