Should governments prioritize limiting farmland expansion to protect wildlife from conflict?
Researchers published a study in PNAS Nexus on 7 July 2026 predicting that the area at high risk of elephant crop raids in Southern Africa could grow by 33% to 100% by 2085. The analysis drew on reported raids from 2004 to 2020 across 38 communal conservancies in Namibia.
Why it matters
Human population growth, expanding cropland and increasingly dry conditions are intensifying encounters between elephants and farmers, a pressure that bears on the region's roughly 290,000 savanna elephants. The findings suggest conservation and land-use planning will face growing strain as conflict hotspots spread.
The projections are modeled outcomes based on 2004 to 2020 raid reports from 38 Namibian conservancies, not direct observations of future conflict. Whether actual raid rates will track the modeled scenarios depends on future population, land-use and climate trajectories that remain uncertain.
The players
PNAS Nexus
PNAS Nexus is an open-access interdisciplinary journal published by the Proceedings of the National Academy of Sciences that publishes peer-reviewed research across scientific fields.
The details
Researchers combined causal statistical methods with machine-learning models, mapping hotspots using vegetation cover, distance to rivers, roads and wildlife fences, population density and vegetation productivity. Drier conditions within protected elephant habitats predicted more wet-season raids in neighboring communities, suggesting shortages of natural resources push elephants toward farmland.

2085: Projected endpoint for expanded high-risk crop-raid areas.
Big Picture
The study builds on Namibia's communal conservancy system, which gives local communities a stake in wildlife management, by using its conservancy-level crop-raid records to project conflict through 2085. It extends that record from past incidents into long-range scenarios for the wider Southern African elephant range.
For readers following wildlife and agriculture, the findings point to rising crop losses for farmers near elephant habitat as cropland expands. They also signal that conservation policy in the region will increasingly weigh the cost of conflict alongside protection goals.
The takeaway
Reducing elephant conflict will depend on how communities balance farmland expansion with natural resource availability inside protected habitats. Monitoring crop-raid data over time can help flag emerging hotspots before losses mount.
