World Toilet Day 2015: Making sanitation sustainable and safe

By Dr Michael Templeton, Reader in Public Health Engineering

Today, Thursday 19th November, is World Toilet Day. Sadly, it is estimated that 2.5 billion people around the world still lack access to an adequate toilet. Many others rely on only basic pit latrines which eventually fill up and can become unsanitary. Many countries failed to meet their Millennium Development Goal target for access to improved sanitation, and the recently stated Sustainable Development Goals continue to emphasise improving sanitation as a key objective towards global development.

Research at Imperial College London by the group of Dr Michael Templeton in the Environmental and Water Resource Engineering section of the Department of Civil and Environmental Engineering is investigating ways to make sanitation more sustainable and safer.

Making it pay by simple addition: win-win solutions for health and the environment

By Dr Kris Murray, Grantham Lecturer in Global Change Ecology

Our planet is ill. Ongoing loss and endangerment of species, degradation of marine and terrestrial ecosystems and their services, and man made changes to the global climate are dramatic symptoms of a major decline in the planet’s environmental health.

In glaring contrast, human health has improved, in some cases radically. Decreases in malnutrition, mortality due to infectious diseases and infant mortality rates, accompanied by substantial increases in life expectancy, can be observed in every major region of the world.

So why is health winning a war, while the environment is losing one?

WaterAid UK / International World Toilet Day

Today 36 prominent international health and development experts including representatives from WaterAid, The World Medical Association, the Institute of Global Health Innovation, Amref Health Africa,  Bangladesh Medical Association, British Medical Association, Commonwealth Medical Association, Global Health Council, Indian Medical Association, International Confederation of Midwifes, Nigerian Medical Association, and the Royal College of General Practitioners amongst many others, have called for an end to a crisis that has claimed the lives of over 10 million children under the age of five since the year 2000.  

In an Open letter to the Secretary-General of the United Nations, Ban Ki Moon, the signatories, representing over 620,000 health professionals globally, highlight the desperate waste of life caused by people not having access to a basic toilet.
