Zimbabwe’s government has begun piloting cloud seeding, a technique that uses aircraft or ground generators to encourage rainfall from existing clouds, as forecasters warn the coming season could bring a severe El Nino-linked drought. The move, confirmed in government briefings in late September, sits alongside a wider six-pillar agricultural strategy announced by the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development.
Cloud seeding works by dispersing particles, typically silver iodide, into clouds that already contain moisture, encouraging water droplets to form and fall as rain more efficiently. It cannot create rainfall where no moisture exists, and its effectiveness varies considerably depending on atmospheric conditions, which is why meteorologists generally describe it as a marginal enhancement rather than a guaranteed drought solution. Zimbabwe’s programme is understood to be a limited pilot rather than a nationwide rollout, targeting specific catchment areas ahead of the main rainy season.
Grain reserves as the other line of defence
The cloud-seeding pilot follows months of work rebuilding Zimbabwe’s strategic grain reserves, which officials reported reaching close to a million tonnes in surplus stock earlier in 2026. That stockpile is intended to buffer consumers against price spikes if the harvest falls short, functioning as a more predictable safeguard than weather modification, which by its nature cannot be relied upon to deliver a specific outcome.
Agriculture permanent secretary Obert Jiri has framed the government’s approach as six interlocking pillars: strategic grain reserves, climate-smart farming practices, agricultural finance, livestock feed security, strategic food imports where needed, and improved early-warning systems. Cloud seeding falls under the climate-smart practices pillar, alongside the near-simultaneous launch of a new climate-resilient wheat variety, SW9104, bred to yield up to 10.5 tonnes per hectare under favourable conditions. Officials have presented the two initiatives as complementary: one aims to make more rain fall, the other to make better use of whatever rain does arrive.
A regional drought pattern, not an isolated risk
Zimbabwe’s preparations reflect a broader concern spreading across Southern and East Africa. Forecasters at the US-funded Famine Early Warning Systems Network flagged a heightened risk of below-average rainfall across large parts of the region in their September 2026 outlook, a pattern separately confirmed for the Horn of Africa by regional meteorological agencies. While Zimbabwe’s exposure is distinct from that of Ethiopia, Somalia or Kenya, the underlying driver, an unusually strong El Nino pattern disrupting normal rainfall distribution, is shared across the wider region.
Weather modification programmes have a long, mixed history globally, and independent verification of how much additional rainfall Zimbabwe’s pilot actually produces will likely take at least a full season to assess properly. Meteorologists caution that any apparent success is difficult to attribute cleanly to seeding rather than natural variability, since it is impossible to know with certainty how much rain would have fallen without intervention.
For Zimbabwean farmers watching the skies ahead of planting season, the more concrete signals of government intent are the reserves already stockpiled and the new seed variety already on sale, both of which offer a hedge regardless of how much rain the cloud-seeding pilot delivers this season.
Regional experience with cloud seeding elsewhere has been mixed enough that most meteorological agencies treat it as a supplementary measure rather than core drought policy. South Africa and Kenya have both experimented with limited seeding programmes in past drought years, generally reporting modest and difficult-to-verify gains. Zimbabwean officials have not disclosed the scale of investment behind the current pilot, nor set out clear criteria for judging its success, which independent meteorologists say will make it hard to assess objectively once the season ends.
