Drought Model Warns of Shrinking Herds in Southern Africa
Researchers project that drought will reduce livestock numbers and widen wealth gaps across seven southern African nations.

Should governments fund feed aid for drought-hit herders, even if wealthier owners benefit most?
Researchers modelled how climate-driven rainfall changes will affect livestock herds and pastoralist wellbeing in Botswana, Eswatini, Lesotho, Mozambique, Namibia, South Africa and Zimbabwe. The agent-based model found that drought reduces herd sizes and that owners who can afford supplemental feed keep a larger share of their animals.
Why it matters
Herds serve as savings for pastoralists, who depend on wet-season rains to grow fodder, so drought erodes both income and assets. The findings suggest that without intervention, drought could deepen economic inequality among livestock keepers in the region.
The model covers seven nations and three scenarios, comparing a baseline climate-change projection against an intervention in which supplemental feed is supplied to herders. Exact herd-size changes and inequality measures for each scenario are not stated in the extraction.
The players
Meat Naturally
A South African meat-marketing initiative that partners on a mobile-slaughter service operating in South Africa.
Conservation International
A global nonprofit conservation organization that partners with Meat Naturally on the mobile-slaughter service in South Africa.
The details
Researchers linked rainfall projections for the seven countries to livestock numbers and individual pastoralists' wealth. Providing supplemental feed alone increases herd sizes, while combining mobile slaughtering trucks with improved seasonal forecasts can largely neutralise drought's inequality-amplifying effects.

Agriculture Outlook
The study applies agent-based modelling, a method for simulating individual herders' decisions, to show how drought affects both herd totals and wealth distribution. It extends earlier livestock-resilience work by testing mobile slaughter and seasonal forecasting as mitigation tools.
For livestock keepers, drought erodes the herds that act as savings, so access to feed and slaughter markets can decide who stays solvent. The findings point to mobile slaughter and better seasonal forecasts as practical tools to protect smaller herd owners.
The takeaway
Protecting smaller livestock keepers during drought may depend less on herd size alone and more on timely feed access, market outlets for animals, and reliable seasonal forecasts. Early planning around these tools could limit the widening wealth gap the model projects.
