In the neighborhoods of Benguela province, the water has receded, but for thousands of Angolans, the disaster is far from over. In areas like Calomanga, hundreds of families continue to sleep in the open, their lives reduced to the few possessions they could carry before the Cavaco River breached its banks.
The collapse of the Cavaco River dike on April 12, 2026, was not merely a consequence of heavy rainfall, but a failure of infrastructure that had been deteriorating for decades. According to a report by Human Rights Watch, the disaster killed at least 19 people and left 31 others missing, displacing thousands and leaving the region’s most vulnerable populations in a state of precariousness.
For those now residing in overcrowded temporary shelters, the immediate crisis of drowning has been replaced by a struggle for basic dignity. Reports from the ground describe a lack of sanitation, food shortages, and a distribution of aid that many residents claim is opaque, and inequitable.
A Legacy of Infrastructure Neglect
The scale of the destruction suggests a foreseeable tragedy. Local residents and journalists report that the Cavaco River dike—the primary line of defense for the city—had not undergone significant maintenance since 2002. This 24-year gap in upkeep left the structure unable to withstand the seasonal pressures of heavy rainfall.
“The dike protecting the city had not been maintained since 2002,” said Dino Calei, a local journalist who has monitored the impact of the floods. In neighborhoods like Tchipiandalo, the result was total: Calei noted that significant portions of the community have practically ceased to exist.
The failure was not a surprise to those living in the shadow of the dike. A 35-year-old resident of Calomanga recalled warning local administrators during public consultations and making pleas through local radio stations. Those warnings went unheeded. On the morning of April 12, the river entered the neighborhood around 8 a.m. Without warning, sweeping away children and the elderly.

Inhumane Conditions in Displacement Centers
While the Benguela provincial government established temporary accommodation centers at the Ombaka National Stadium and the old and new Campismo facilities, those on the inside describe a different reality. Volunteers and lawyers assisting the displaced say the centers are incompatible with basic standards of human dignity.
Maria do Carmo, a volunteer at the old Campismo, highlighted the specific risks facing women and children. She described bathrooms that lack privacy and cleanliness, forcing many to relieve themselves in the open to avoid infection. By early May, some centers had reportedly run out of charcoal for cooking, forcing victims to organize their own means of survival.
The crisis is compounded by allegations of unfair aid distribution. Tiago Ngana, a local activist, noted that while aid has arrived from across the country, it is not reaching the most desperate. “Some people lost everything and received only a bag of cement, while others have access to more support,” Ngana said.
A Pattern of Recurrent Vulnerability
The disaster in Benguela did not happen in isolation. Weeks prior, heavy rains caused significant flooding in Luanda, the capital, killing at least a dozen people. Together, these events underscore a systemic failure in Angola’s disaster preparedness and urban planning.
Human Rights Watch argues that the Angolan government is in breach of several international treaties, including the International Covenant on Economic, Social and Cultural Rights and the African Union Convention for the Protection and Assistance of Internally Displaced Persons in Africa (the Kampala Convention). These agreements obligate the state to prevent foreseeable risks and ensure nondiscriminatory assistance to those displaced by disaster.
“Governments have an obligation not only to respond in an emergency but also to uphold their populations’ human rights,” said Sheila Nhancale, Africa researcher at Human Rights Watch. She emphasized that the affected families deserve more than mattresses and cement; they deserve an explanation as to why the dike was allowed to fail.
The physical toll extends beyond housing. Satellite imagery analyzed by Human Rights Watch confirms the collapse of the dike in at least three locations and the destruction of two bridges—one pedestrian and one railway—along with significant damage to National Road 260, which has hampered the delivery of emergency supplies to the hardest-hit areas.
The immediate focus now shifts to the demand for an independent and credible investigation into the dike’s collapse. Survivors and legal advocates are calling for a transparent accounting of the funds allocated for infrastructure maintenance over the last two decades and a concrete plan for the permanent resettlement of those whose homes are now uninhabitable.
