Health impacts of environmental conditions
What this life looks like
You protect communities from the environmental conditions that make people sick. Environmental Health Officers investigate and control environmental hazards to human health — contaminated water, unsafe food, air pollution, housing hazards, vector-borne disease breeding sites, and occupational health risks. It is a role that sits between public health, environmental science, and regulatory enforcement, and it is critically underfunded across Africa.
What she actually does
You inspect water sources, food establishments, housing, waste sites, and workplaces for health hazards, collect water and food samples for laboratory testing, investigate disease outbreaks linked to environmental causes, enforce public health and environmental regulations, educate communities and businesses on sanitation and hygiene, manage vector control programmes (for mosquitoes, rodents, and other disease vectors), and respond to environmental health emergencies.
Where you can work
| Sector | Places in Africa |
|---|---|
| Local Government | Municipal environmental health departments — the primary employer of environmental health officers across Africa |
| National Government | National departments of health environmental health directorates, national public health institutes |
| Occupational Health | Mining companies, construction firms, manufacturing plants — occupational and environmental health roles |
| International | WHO Africa, UNEP, CDC Africa — international environmental health programme roles |
Why it matters in Africa
Environmental health risks kill more Africans than malaria. Contaminated water causes diarrhoeal disease that kills hundreds of thousands of children annually. Urban air pollution from traffic and industry causes respiratory disease in major African cities. Inadequate sanitation spreads cholera, typhoid, and hepatitis. And workplace health hazards — from mining dust to pesticide exposure — affect millions of workers. Environmental health officers are the primary protection system against all these threats.

A woman in this field
Lorna Rutto
Kenya
Lorna is a highly renowned Kenyan eco-preneur and the founder of EcoPost, a social enterprise created in response to Nairobi's severe plastic waste management crisis. Leaving her comfortable career in banking, Lorna built a venture that collects immense volumes of urban plastic waste and manufactures it into commercial-grade, eco-friendly plastic lumber. Her sustainable waste management model has diverted millions of kilograms of plastic from fragile ecosystems and landfills, saved hundreds of acres of forests from timber harvesting, and created sustainable jobs and manufacturing livelihoods across Kenya.
Take your first step
- Research the Environmental Health Association of South Africa (EHASA) at ehasa.co.za and the Institute of Public Health and Environmental Health Administrators (IPHEHA) in Nigeria — they are the professional bodies for environmental health practitioners
- Study what the WASH (Water, Sanitation, and Hygiene) framework involves and how it is implemented in African communities — it is the most important public health framework for environmental health in Africa
- Contact your local municipal environmental health department and ask about the possibility of observing an inspection — seeing the practical work of an environmental health officer is the best introduction to the career
- Research what Ebola, cholera, and typhoid outbreaks look like from an environmental health investigation perspective — the WHO and CDC publish outbreak investigation reports that show exactly what environmental health officers do in the field
