Zimbabwe’s renewed emphasis on completing major dam projects — especially Gwayi-Shangani and Kunzvi — signals a welcome shift from treating water infrastructure as a background technical matter to recognising it as a central pillar of economic security.
In a country where drought cycles appear to have become more frequent, rainfall less predictable, and the margins for agricultural failure narrower, the case for storage capacity is no longer ideological; it is practical. Dams, when completed and properly managed, can provide irrigation water, stabilise livestock production, support fisheries and hydropower, and protect urban supplies. In the language of development planning, they are not just “waterworks”. They are nation-building assets.
The story from Mangwe District in Matabeleland South frames this renewed push as part of the Agriculture Food Systems and Rural Transformation Strategy 2 (AFSRTS2) for 2026–2030, under the “Dam as an Economy Model”.
That framing matters. Too often, infrastructure programmes are celebrated for the day the first stone is laid or the dam wall rises — only for the expected economic transformation to stall when water is not translated into productive activity.
Concrete and earthworks do not feed people by themselves. A dam’s promise can remain trapped in the language of percentages and projected timelines unless the country commits to the harder, more continuous work of converting stored water into livelihoods.
There is also something politically and economically significant about the Government’s focus on specific dams with clear completion targets. Prof Obert Jiri says Gwayi-Shangani is now over 70% complete and could be finished at the end of 2026, while Kunzvi is over 75% complete, with pipeline development from Kunzvi to Harare already underway and impounding having started. Such statements do more than communicate progress; they invite accountability. In development, targets are not just promises — they are tools that allow citizens, farmers, investors, and oversight bodies to test whether public resources produce outcomes on schedule.
Gwayi-Shangani, is expected to improve water security for Bulawayo and unlock irrigation potential from existing dams such as Upper Ncema, Lower Ncema and Insiza as demand for potable water shifts. Kunzvi is presented as a solution not only for Harare’s requirements but also for irrigation and downstream opportunities. If these linkages are real, then the dams will become catalysts for “second-stage development”: the agricultural and industrial ecosystems that can only grow when water is reliable. This is where the “Dam as an Economy Model” must move to practice.
Zimbabwe’s scale of opportunity is striking. The Government points to a network of more than 10 600 water bodies, including large dams capable of irrigating over two million hectares. Zimbabwe requires at least 350 000 hectares under irrigation to guarantee cereal self-sufficiency.
These numbers are not just statistics; they represent a potential shift from a rain-dependent agriculture that repeatedly collapses under drought pressure to a more predictable food system. In an environment where households face the painful arithmetic of failed harvests and rising food prices, irrigation is effectively a form of economic protection.
Drought and El Niño risks have made water security a national economic issue rather than a narrow agricultural concern. But water security is not achieved simply by capturing water in a reservoir. It is achieved when water reaches crops, livestock and communities on time and at manageable cost.
There are suggestions that dams can be paired with irrigation schemes to generate forage — cereal stover and other feed resources that help farmers bridge the dry season. This is precisely the kind of integrated planning that Zimbabwe should deepen. Dams should be treated as platforms for value chains, not isolated projects. When the water system is complemented by pasture management, crop choice planning, and market access for livestock and crops, resilience becomes durable rather than temporary.
The private sector endorsement from the Chamber of Commerce chapter adds another dimension: dams are positioned as national investment platforms with downstream impacts on mining, manufacturing, fisheries, tourism, hydroelectric power generation and urban supply. That breadth is persuasive because it acknowledges reality.
Water infrastructure affects the entire economy: it influences operating costs for industries, the reliability of power supply, the growth of agro-processing, and the attractiveness of regions for investment. Still, private sector confidence should be matched with public-sector discipline. Investors will look for predictable timelines, transparent procurement, credible maintenance plans, and clarity on how irrigation schemes and water delivery systems will be managed.
The Government argues that dams will cushion the country against a projected El Niño by improving storage and supporting hydropower, irrigation and downstream activities.
This is a logical strategy because the drought calendar does not wait for procurement delays. Yet the country must avoid a complacent “wait until the dam is finished” mentality. If impounding has already begun at Kunzvi and works continue at other sites, Zimbabwe should concurrently accelerate the readiness of irrigation and water delivery components — so that the first stored water quickly becomes first productive gains.
In short, Zimbabwe’s dam programme deserves strong support. It is difficult to overstate the value of water infrastructure in a climate-challenged agricultural economy. But completion — while necessary — is not sufficient.
The next phase must ensure that every dam becomes a working economic engine: water delivered reliably to fields and livestock systems, institutions capable of managing operations and maintenance strengthened, and downstream value chains supported through inputs, extension, and markets.
If Zimbabwe finishes Gwayi-Shangani and Kunzvi by the end of 2026 as projected, it will have achieved a major engineering milestone. The real success, however, will be measured later — by irrigated hectares actually under production, herds surviving the dry season, food security improving sustainably, and rural economies growing around water. Dams can be Zimbabwe’s insurance policy against climate volatility. But like all insurance, their value depends on timely, responsible execution — and on building the economy that lives downstream.
