WORLD ENVIROMENTAL HEALTH DAY

-SEPTEMBER 26

World Environmental Health Day, observed annually on September 26 (4th of Mehr in the Iranian calendar), was commemorated this year by the Department of Environmental Health Engineering at Shiraz University of Medical Sciences with a diverse set of academic, educational, and community-based programs. Aligned with the international theme “Clean Air, Healthy People,” our department designed activities to increase awareness, promote dialogue among experts, and encourage environmentally responsible behaviors among both the university community and the public.

The message of World Environmental Health Day 2026 is: “Standing with Science to Protect Communities through Environmental Health.” This theme is not merely a call to protect the environment; it connects science, evidence and collective responsibility directly with the protection of human health. The greatest need today is to understand that environment and health are not two separate subjects. The air we breathe, the water we drink, the soil in which our food is grown, the temperature in which our bodies survive, and the biodiversity surrounding us are all invisible foundations of our health. If the environment becomes unhealthy, human beings cannot remain healthy; and an unhealthy way of life, in turn, further damages the environment.

The global population has crossed eight billion, and water scarcity is no longer a concern for the future—it is a reality of the present. According to the United Nations, around 3.6 billion people face inadequate access to water for at least one month every year. Since 2000, flood-related disasters have increased by 134 percent, while the frequency and duration of droughts have increased by 29 percent. This means not merely that water is becoming scarce; it also means that the conditions for disease, displacement, food insecurity and psychological stress are becoming more severe.

The harshest face of climate change is now visible on the human body itself. According to the World Health Organization (WHO), heat-related mortality among people aged over 65 increased by approximately 85 percent during 2017–2021 compared with 2000–2004. Extreme heat is not simply a matter of discomfort; it can aggravate cardiovascular and respiratory diseases, diabetes, mental-health conditions and several other illnesses. Therefore, the time has come to stop treating climate policy and health policy as separate domains. Environmental risks have become a silent global health crisis. The WHO estimates that nearly 24 percent of deaths worldwide could be prevented by reducing environmental risks. Air pollution alone is associated with millions of premature deaths every year. Therefore, increasing the number of hospitals cannot be the ultimate objective of a health system. If the air is polluted, water is unsafe, soil is contaminated and cities are becoming hotter, expanding treatment facilities while leaving the causes of disease untouched will always remain an incomplete response.

The world must now move from a “treatment-oriented health system” to a “prevention-oriented environmental health system.” A hospital responds after illness occurs, but clean air can reduce the likelihood of disease before it develops. Safe drinking water reduces the burden on hospitals. Green spaces support mental well-being. Clean energy reduces the risk of respiratory illnesses. Efficient public transportation can simultaneously reduce air pollution and carbon emissions. This is the true synergy between environment and health. The very definition of development therefore needs to be reconsidered. High-rise buildings, wider roads, greater consumption and increased production do not automatically constitute development. True development is that which gives equal consideration to human beings, rivers, forests, soil, animals, birds and the lives of future generations. The United Nations Environment Programme’s latest Global Environment Outlook-7 has also highlighted that investment in a stable climate, healthy nature, better land management and a pollution-free environment can generate substantial economic benefits over the coming decades, whereas the destructive path being followed today could impose enormous costs on climate, biodiversity, land and human health.

There is also a significant opportunity here for India. Water conservation must become not merely a government programme but a people’s movement. Rainwater harvesting, revival of ponds and lakes, protection of the natural flow of rivers, scientific groundwater management, prevention of water wastage and expansion of water-efficient agricultural technologies are all environmental measures that are equally important health measures. Every restored pond does more than conserve water; it also contributes to reducing the risks of future disease, displacement and food insecurity. Similarly, the protection of forests and biodiversity must be brought to the centre of the health agenda. When human beings have cut down forests, destroyed wildlife habitats and disrupted the balance of nature, the consequences have extended far beyond trees and animals. The WHO increasingly emphasizes a “One Health” approach that views human, animal and environmental health as interconnected. Its message is clear: human health cannot be protected as an isolated island. A healthy human being requires a healthy ecosystem.

The new direction should be for every city to prepare an “Environmental Health Budget.” Such a budget should not focus only on roads and buildings but also include indicators such as per-capita green space, clean air, safe water, tree cover, water harvesting, waste management, protection from extreme heat and biodiversity. Schools should not limit environmental education to planting a sapling on Environment Day. Children should instead be encouraged to become local guardians of the rivers, ponds, groundwater, air quality and biodiversity of their own surroundings. Hospitals, too, should become more energy-efficient, low-carbon and water-conscious. Science should guide this movement, while compassion should provide its foundation. Data tells us the scale of the crisis, but compassion inspires us to act. We must accept that nature is not an external object that we are merely trying to save—we ourselves are an inseparable part of nature. Saving a river means protecting the water that sustains our own bodies; saving forests means protecting the air we breathe; saving soil means protecting our food; and protecting the climate means protecting our future.

The need today is not for a debate between environment and development, but for development that respects and sustains the environment. Science is showing us the way, while nature is warning us about the cost of inaction. The choice now rests with humanity: will we behave as owners who exhaust our resources, or as custodians who preserve them for generations to come? The real message of World Environmental Health Day 2026 should be clear: the Health Ministry alone cannot create a healthy society, and the Environment Ministry alone cannot protect a healthy planet. The two must move together. Clean air, pure water, healthy soil, safe food, a stable climate and rich biodiversity are not merely environmental concerns; they are fundamental conditions of human life.

Ultimately, we must create a world where there are fewer hospitals and more healthy lives; where buying bottled water is not a necessity but safe natural water is a normal part of everyday life; where trees are not treated as decoration but as companions of life; and where rivers are not viewed merely as resources but as living heritage. Healing the environment is healing human health, and ensuring healthy human life is itself the greatest protection we can offer the environment. This integrated vision can create a new trinity of a healthy environment, healthy human beings and a healthy world. That is the true meaning of standing with science—and the real significance of World Environmental Health Day.

This year's theme directly aligns with WHO’s science-based decision-making narrative and highlights the role of environmental health professionals as applied public health scientists translating research into policy, regulation and community protection.As always, WEHD can be used to highlight any Environmental Health topic that is relevant to your local or regional part of the world.

As part of the Breathe Kampala Campaign and in commemoration of the 2025 World Environmental Health Day, students from the Makerere University Environmental Health Students’ Association (MUEHSA), joined by the Mulago Environmental Health Students’ Association (MEHSA), conducted a community outreach at Komamboga Health Centre III on Friday, 26th September 2025. These were joined by Ms. Sylvia, the Forestry Officer at Kampala Capital City Authority (KCCA) and a team from Tree Adoption Uganda (TAU). The entire team was warmly received by Dr. Daphne Akoth, the in-charge of Komamboga Health Centre III who consented to procession of the activities while offering guidance. The day’s activities focused on health education and tree planting, aimed at raising awareness about air pollution and promoting environmental stewardship within the community.The event followed a pre–World Environmental Health Day webinar held on 25th September, where experts and students reflected on the theme “Breathe Kampala, Breathe Africa: Youth, Science, and Health in the Fight for Clean Air.” The outreach served as a practical follow-up to translate discussion into community action.
