The World Bank has issued a stark warning on the devastating impact of poor sanitation across Africa, revealing that the continent loses an estimated $200 billion annually due to inadequate hygiene and sanitation systems.
The new report, titled “The Global Sanitation Crisis: Pathways for Urgent Action”, highlights the economic, health, and environmental consequences of neglecting sanitation and calls for urgent intervention from governments and stakeholders.
According to the global lender, poor sanitation is one of the most under-addressed development challenges despite its far-reaching implications. Nearly two in five people worldwide still lack access to safe sanitation facilities, with Africa shouldering a disproportionate burden.
The Bank estimates that Africa’s Gross Domestic Product could grow by as much as five percent if countries make adequate investments in water and sanitation infrastructure.
The World Bank report underscores that poor sanitation drains Africa’s wealth through reduced productivity, healthcare costs, and environmental degradation.
Every dollar invested in sanitation services yields up to seven dollars in economic returns, yet chronic underfunding has left millions vulnerable to diseases such as cholera, typhoid, and diarrhoea.
The institution explained that the $200 billion annual loss stems not only from treatment of preventable illnesses but also from lost work and school days.
Children often miss classes due to waterborne diseases, while adults are unable to work, further stalling economic growth.
“Resilient sanitation reduces pollution, cuts greenhouse gas emissions, and protects global ecosystems.
In Africa, the absence of such systems perpetuates poverty and undermines long-term growth prospects,” the report stated.
Health experts have long linked poor sanitation to preventable deaths, particularly among children under five.
The United Nations estimates that 3.5 billion people globally lack access to safe sanitation, making it a leading cause of disease outbreaks.
In Africa, rapid urbanisation has worsened the problem, with informal settlements lacking sewage systems, leaving residents dependent on unsafe alternatives that contaminate water sources.
The World Health Organisation has repeatedly emphasised that poor sanitation keeps millions trapped in a vicious cycle of ill health and poverty.
Without access to clean toilets and effective waste management, communities remain exposed to infections that claim hundreds of thousands of lives each year.
The World Bank also warned that climate change is compounding the effects of poor sanitation.
Rising sea levels, frequent flooding, and prolonged droughts have damaged fragile sanitation infrastructure, leaving many communities at greater risk of contamination and disease.
“In low- and middle-income countries, one-third of urban residents face a triple burden of inadequate sanitation, poverty, and climate risks,” the report noted.
“Investing in climate-resilient sanitation systems can break this cycle and create healthier, more productive communities.”
Beyond health and the economy, poor sanitation has a profound social impact.
The Bank’s findings show that inadequate sanitation facilities in schools discourage enrollment, particularly among adolescent girls who require sex-specific facilities.
Citing examples from India and Brazil, the report revealed that improved access to clean toilets led to higher school attendance and completion rates.
The World Bank stressed that addressing poor sanitation in Africa could yield similar outcomes, improving literacy, gender equality, and long-term social development.
To reverse the staggering economic and health costs, the World Bank has urged African governments and development partners to prioritise sanitation in national policies.
The report recommends:
Increased funding for inclusive and climate-resilient sanitation systems.
Adoption of innovative technologies for safe waste management.
Integration of sanitation planning into broader urban development frameworks.
Public awareness campaigns to promote hygiene and sanitation practices.
Partnerships with private sector players to scale investments.
The Bank also highlighted the potential of circular economy approaches, where faecal sludge and wastewater are converted into energy, water, and other valuable resources.
Such initiatives, it said, would not only reduce pollution but also create jobs and boost local economies.
Concluding its findings, the World Bank called for immediate and coordinated action to address poor sanitation.
It warned that without urgent investment, Africa risks losing its demographic dividend and undermining efforts to achieve the Sustainable Development Goals, particularly Goal 6 on clean water and sanitation for all by 2030.
“Achieving climate-resilient urban sanitation is possible, but action must begin now,” the report stressed.
“Governments, service providers, businesses, and communities must work together to build systems that protect people, prosperity, and the planet.”
As the continent continues to grapple with rapid urbanisation, weak infrastructure, and the threats of climate change, experts agree that tackling poor sanitation will be pivotal to Africa’s economic transformation and human development.
