Ethiopia’s Gamo Zone Landslides Signal Recurring Climate Disaster Risk and Weak Resilience Gains

The disaster struck last week, when intense and sustained rainfall saturated mountainous slopes across Ethiopia's Gamo Zone. The result was a series of devastating landslides that have now claimed 125 lives. The toll has risen steadily, with regional authorities confirming 70 deaths earlier in the week before updating the figure to 125 by Sunday. Over 11,000 people have been displaced, forced from their homes by the widespread destruction.

The event unfolded in a known high-risk area. The Gamo Zone's steep, highland terrain, particularly around Arba Minch, is inherently vulnerable. When prolonged rains infiltrate the soil, pore water pressure builds, weakening the slope's stability. This triggers failures where the resisting forces within the soil can no longer counteract gravity, sending large volumes of mud and debris downhill to bury homes and infrastructure.

The national political response has been swift. Prime Minister Abiy Ahmed visited the affected areas on Saturday, offering condolences and pledging government support. His visit underscores the national significance of the tragedy and the pressure on authorities to manage the recovery and address the recurring risk in these vulnerable highland communities.

Historical Precedent and Climate Context

This latest disaster is not an isolated tragedy but a grim echo of a pattern. Just over a year ago, in July 2024, a similar sequence of intense rains triggered catastrophic landslides in the neighboring Gofa Zone. That event claimed at least 257 fatalities and displaced over 15,000 people, becoming the deadliest landslide in the nation's recorded history. The scale of loss in the Gamo Zone this week, with a death toll now at 125 and over 11,000 displaced, shows the vulnerability remains acute and the risk of recurrence is high.

Ethiopia's exposure to these events is amplified by a stark climate imbalance. Despite contributing only 0.53% of global emissions, the country is ranked among the top 10 most vulnerable nations to climate disasters. This is climate injustice in practice: the nation bears a disproportionate burden of extreme weather it did not create. The mechanism is clear-rising global temperatures intensify rainfall patterns, leading to heavier, more erratic downpours that saturate mountainous soils and trigger failures.

The outlook for the coming months increases the likelihood of further events. Regional forecasts indicate a 45% chance of above-average rainfall during the critical March–May season. This sets the stage for more saturated ground and heightened instability in highland zones like Gamo and Gofa. The historical precedent of 2024, combined with this forecast and the nation's systemic vulnerability, suggests the current disaster is part of a worsening trend, not a one-off occurrence.

Structural Vulnerability and Adaptive Capacity

The repeated failure of saturated slopes points to a deeper, systemic issue: inadequate long-term land-use planning and slope protection. Highland communities in the Gamo Zone are often settled on or below steep terrain where rainfall runoff naturally concentrates. When prolonged rains infiltrate the soil, pore water pressure builds, weakening the slope's stability. In many cases, the resisting forces within the soil are no longer able to counteract gravity, leading to rapid failures. The evidence shows that saturated soils can lose stability rapidly, especially where vegetation cover has been disturbed or drainage is poor. This mechanism is not new; it was the same process that triggered the deadly 2024 landslides in the neighboring Gofa Zone.

Recovery efforts are hampered by the very conditions that caused the disaster. Search and rescue operations have been complicated by blocked roads, damaged bridges, and continuing rainfall. This pattern of damaged infrastructure and ongoing rain, which also hindered relief in 2024, creates a vicious cycle. It delays aid, increases the risk to rescue workers, and prolongs the suffering of displaced populations. The government's response, including a three days of mourning and the mobilization of resources, is a standard, high-profile reaction to national tragedies. A relief fund has been established to collect donations from private citizens and businesses.

Yet the effectiveness of this mobilization depends entirely on coordination and reach. The challenge is to get supplies to remote, displaced communities where residents were observed searching through deep mud deposits for survivors. Without robust logistics and local partnerships, even well-intentioned aid can be delayed or misdirected. The bottom line is that while the state can rally quickly, the adaptive capacity of these vulnerable highland zones remains low. The recurring risk demands more than a reactive response; it requires a sustained investment in slope stabilization, improved drainage, and land-use policies that move settlements away from the most hazardous paths.

Catalysts and Watchpoints

The path from this week's tragedy to lasting change hinges on a few critical catalysts. The immediate watchpoint is the final toll. The death count has already climbed to at least 102, with dozens still missing. As search operations continue, this figure will serve as the clearest gauge of the disaster's full human cost and the urgency for a durable response.

Beyond the numbers, the key signal will be the government's shift from relief to resilience. The declaration of a three days of mourning and the mobilization of a relief fund are standard reactions. The real test is whether these efforts are followed by concrete, long-term adaptation funding. Watch for official announcements detailing specific infrastructure projects for slope stabilization and improved drainage in the Gamo Zone. Without such commitments, the cycle of disaster and recovery is likely to repeat.

The most critical watchpoint for preventing future loss of life is the implementation of early warning systems and community relocation plans. Officials have already urged residents in vulnerable areas to take precautions, but warnings are only effective if backed by action. The government must move swiftly to install reliable monitoring systems that can detect rising soil moisture and slope movement. Simultaneously, any plan to relocate communities from the most hazardous paths must be developed and funded. The 2024 Gofa disaster, which killed over 200, showed that such measures are possible. The recurrence of a similar event in Gamo this week suggests they are not yet a priority. The coming weeks will reveal whether this tragedy finally compels a change in that calculus.
