A group of 176 Zambian farmers has filed a US$80 billion lawsuit against a Chinese state-owned mining company over a major toxic spill. In February, the collapse of a dam that was supposed to control mining waste released 50 million litres of toxic wastewater into the Kafue River system, killing fish, destroying crops and contaminating water sources for thousands of people. The compensation demand highlights broader questions about mining governance, environmental oversight and corporate accountability.

What’s this lawsuit about, and why are farmers seeking US$80 billion?

The farmers are suing Sino-Metals Leach Zambia, a subsidiary of the Chinese state-owned China Nonferrous Metal Mining Group, because on 18 February, the company’s tailings dam collapsed, releasing an estimated 50 million litres of acidic, toxic wastewater and up to 1.5 million tonnes of waste material into the Kafue River. This led to water pollution affecting communities in Chambishi and Kitwe, far beyond the immediate mining area.

The lawsuit reflects real harm and frustration. From the farmers’ perspective, the company is clearly responsible. Their livelihoods have been destroyed, their land contaminated and their future made uncertain. In that context, seeking accountability through the courts is a rational response.

That said, the US$80 billion figure is likely exaggerated. It shows the absence of credible damage assessments rather than a precise calculation. When no one provides clear data on losses, communities respond by anchoring their claims in worst-case scenarios.

This case also highlights a broader accountability gap. Mining companies should be held responsible, but governments must also be questioned. These projects are approved, inspected and regulated by state authorities. If a dam was unsafe, why was it authorised? Why was oversight insufficient?

It should be noted that Zambia’s legal framework allows communities to bring such cases domestically, which is a significant step forward compared to earlier cases where affected communities had to sue foreign companies in courts abroad.

What caused the toxic spill?

There is no single, uncontested explanation. There were clear structural weaknesses in the tailings dam. Reports from civil society and media suggest the dam was not built to the required standards under Zambian regulations. But the company argues the dam complied with existing standards and that it was encroachment by surrounding communities that weakened the structure over time.

These two narratives are not mutually exclusive. Even if community interactions with the site occurred, the primary responsibility still lies with the company. Mining operations take place in complex social environments, and companies are expected to anticipate these realities and design infrastructure that is robust enough to withstand them. Ultimately, this incident reflects governance and regulatory failures. It was not an isolated accident.

What were the consequences of the spill?

The impacts have been severe and multidimensional. The spill polluted large sections of the Kafue River, reportedly extending over 100 kilometres. It killed large numbers of fish, contaminated riverbeds and disrupted ecosystems. Agriculturally, farmers using river water for irrigation saw their crops destroyed or rendered unsafe. Livestock and soil quality were also affected. Acidic and toxic substances entered water sources used daily for cooking, drinking and washing, and communities were exposed to serious health risks.

What makes the situation particularly troubling is the lack of reliable and independent data. There has been no transparent and comprehensive assessment released by the government, the company or an independent body. This absence has left communities uncertain about long-term environmental damage and health effects, and fuelled emotionally charged debates instead of evidence-based responses.

Was the disaster preventable?

Absolutely. At a technical level, stronger infrastructure, better-quality materials and stricter adherence to safety standards could have significantly reduced the risk. At an operational level, companies know mining sites are rarely isolated, and community proximity, informal access and social dynamics must be factored in when designing and securing tailings dams.

But prevention also depends heavily on governance. Mining companies are profit-driven entities, and in weak governance environments, the temptation to cut costs is high. This is not unique to Chinese firms. The main difference in how companies operate is not their origin but their context: the same companies often operate very differently in countries with weak or strong regulatory oversight. Where rules are enforced, behaviour improves; where oversight is weak, shortcuts become the norm.

The key issue here is enforcement. Zambia has good environmental laws and standards on paper. The problem is their implementation.

Could this case set a precedent?

This case has the potential to strengthen existing accountability mechanisms rather than create a new precedent. Zambia has seen similar cases before, including lawsuits involving western mining companies. What is different now is the increased legal space for communities to act locally.

If successful, the case could reinforce civil society advocacy for responsible mining, greater transparency and stronger enforcement of environmental regulations. It could also raise awareness among communities living near mining sites about their rights and the risks they face.

USERRA DAS ALMAS, Brazil, Dec 29 2025 – “The work of collecting seeds saved me from depression,” caused by her daughter’s suicide at the age of 29, said Maria do Desterro Soares, 64, who lives in the poor rural community of Jatobá in northeastern Brazil.

She drew her younger sister, Maria de Jesus Soares, 45, who lost her husband in a car accident and also struggles to avoid falling into depression, into the activity. The two walk together for nearly two hours to reach the forests where seeds abound.“The reserve is a great water reservoir. A study we conducted on avoided runoff showed this 6,285-hectare area can retain an astonishing 4.78 billion liters per year” – Gilson Miranda.

They only earn some 1,000 reais (US$185) in a “good year,” but “it’s my work, my pleasure, it’s what I want and I like doing it,” claimed Maria do Desterro, who also makes ice cream and medicines for flu and other illnesses with locally sourced juices, teas, peels, and honey.

She is one of the 121 people trained by the Caatinga Association (AC) through 2023 for the collection and management of seeds from native plants of this biome exclusive to Brazil, as a way to generate income and restore forests.

The association, founded in 1998 to protect the caatinga, the biome of the semi-arid region in the Brazilian northeast, manages the Serra das Almas Natural Reserve (RNSA) and disseminates social technologies for coexistence with the semi-arid ecoregion in surrounding communities.

The caatinga occupies 10% of Brazil’s vast territory and is home to 27 million people. Its vegetation is generally low, with twisted branches and trunks, appearing dead in the dry season and turning green just days after rain. It also features large trees that reach heights of tens of meters.

Coexistence, instead of fighting against nature

To coexist, rather than fighting droughts, is a guiding principle of the actions that are improving life in Brazil’s poorest region, the Northeast, offering a climate lesson for the country and the world.

This slogan, set in motion by civil society organizations, spurred several social technologies as solutions for water scarcity. Best known is the rainwater harvesting cistern for domestic use, with over 1.2 million units built since 2003.

Cisterns, bio-water (a system that cleans household water for reuse in planting), green septic tanks (a concrete tank with soil, filters, and a banana plant base), solar ovens, and eco-efficient stoves are the five tecghnologies being disseminated.

The AC website reports that 1,481 of these “technologies” have been implemented.

The AC has the RNSA for environmental education and as a source of income through eco-tourism. It works in 40 communities nearby where some 4,000 families live, implementing social technologies and supporting the conservation of the reserve and the entire caatinga.

Headquartered in Fortaleza, the capital of the northeastern state of Ceará, and in Crateús, in the west of that same state near the RNSA, the association stands out from other non-governmental organizations by having this conservation unit of 6,285 hectares of dense forests and four streams.

The caatinga mitigates climate change

“The reserve is an open-air laboratory, where research on fauna, flora, carbon, and water takes place, so we can understand the importance of this area, and of the entire caatinga,” explained Gilson Miranda, a biologist and manager of the RNSA for the Caatinga Association.

In 2015 – 2022, the caatinga was responsible for nearly 40% of the carbon removed from the atmosphere in Brazil, he said, based on a study by São Paulo State University on greenhouse gas capture.

This is because the rapid regreening of the vegetation, an indicator of intense photosynthetic activity when it rains, makes the caatinga a major greenhouse gas sink, different from the Amazon, which is an immense carbon reservoir.

“That is why preserving and conserving the caatinga is strategic in a climate adaptation scenario,” said Miranda in an interview with IPS.

This biome, exclusive to Brazil, covers an area of 844,453 square kilometers.

Water is another wealth of Serra das Almas, which was designated a Private Natural Heritage Reserve (RPPN) in the year 2000.

“The reserve is a great water reservoir. A study we conducted on avoided runoff showed this 6,285-hectare area can retain an astonishing 4.78 billion liters per year,” said Miranda.

Around the springs, there are very tall, green trees that differ from the usual biome. The gameleira (Ficus gomelleira), can reach up to 40 or 50 meters, according to Jair Martins, the tourist guide on hikes along the six trails of Serra das Almas.

This water, retained in the soil by the forests, actually drains slowly. The four springs preserved in the reserve do not dry up, but are unable to sustain year-round the streams that feed the Poti River, whose course passes to the east and north of Serra das Almas.

Nor is this moisture enough to keep the caatinga vegetation green, which is very dry in December, with the green of some shrubs or trees more resistant to water stress.

Mitigated drought

In the surroundings of the RNSA, the drought is harsher.

Maria Clemente da Silva, 59, relies on bio-water to supplement the water she uses to irrigate her small garden. The public water supply only operates for two to three hours per day, which is not enough for cultivating vegetables, such as lettuce and onions, or fruit trees like papaya, banana, acerola, orange, and cashew.

About 100 meters behind her house, a forest of tall, very green trees reveals that, with water, the caatinga vegetation gains exuberance. It is the moisture that remained in a low-lying area of a river that practically dried up due to deforestation and fires set to “clear” the land, explained Elisabete de Souza Soares.

Water is the most keenly felt shortage, according to Souza and other women who spoke to IPS and a group of journalism students visiting the Jatobá community, in the municipality of Buriti dos Montes, in the state of Piauí, where the AC’s socio-environmental actions benefit the population and the protection of the RNSA.

All of them received cisterns, the small three-burner ecological stove, and other “technologies” that reduced difficulties in their lives. “Before the cistern, we would fetch water from a public fountain about a kilometer away, carrying cans on our heads,” recalled Souza.

When she was pregnant with her daughter Maria, 11 years ago, she thought about moving away from the community where she had always lived in search of water. “Now I won’t leave here, where I was born,” she said.

The Caatinga Association adopted a comprehensive conservation model with broad participation from the local population, including in the economic benefits of work within the RNSA, such as guiding ecotourists and providing other services.

The AC’s approach is always socio-environmental, a main component in protecting the reserve and the caatinga in general, stated Miranda.

Inside the reserve, there is a modest hotel that can accommodate up to 36 people. Local tourism tends to expand due to promotion by the governments of the states of Ceará and Piauí, which share the Serra das Almas Natural Reserve.

The nearby Poti River flows through a 140-kilometer-long canyon and has become a major tourist attraction.

The reserve is a legacy of the US Johnson family, owners of the SC Johnson company, which, because it uses vegetable wax for its furniture cleaning and conservation products, imported carnauba wax, a palm abundant in Ceará, Piauí, and Rio Grande do Norte, another Northeastern state.

In 1998, the leader of the family’s fourth generation, Samuel Johnson, repeated an expedition to Ceará that his father had made in 1935 and decided to establish a Caatinga Conservation Fund, using part of his fortune. This led to the RNSA and the Caatinga Association, composed of environmental specialists in the biome.
