Why Sanitation

Public Health, Environment and Sanitation

There are major public health and environmental concerns linked to inadequate urban sanitation. Evidence shows that a large number of diseases are caused by poor water, sanitation and hygiene, with diarrheal diseases being the most significant. According to recent estimates, diarrhoea causes nearly one in every 10 deaths in children under five in India. Another consequence of inadequate sanitation is malnourishment leading to stunting in childhood. From an environmental perspective, the inability to adequately treat wastewater is leading to the pollution of water bodies and contamination of groundwater aquifers.

Economy and Sanitation

These public health and environmental impacts exact a heavy economic cost and limit the development potential of low-income countries such as India. A 2010 study on the economic impacts of inadequate sanitation in India estimated losses to be at 6.4 per cent of the country’s GDP. With a lack of access to adequate sanitation, daily routines are disrupted leading to loss of productivity. Often this economic impact is greater among vulnerable groups such as women, persons with disability and low-income communities, who are also the least able to afford adequate health care.

Climate Change and Sanitation

The effects of poor water and sanitation are further exacerbated by climate change, one of the most significant challenges of our times. Extreme events of precipitation, heat stress, droughts, and flooding are increasingly impacting drinking water and sanitation systems. The United Nations Sustainable Development Goals (SDGs) are a global response to tackling climate change.

Recognising the many disproportionate impacts of inadequate sanitation, SDG 6 was framed to “achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations”. Our work with the urban poor, many of them women, and our onus on inclusive sanitation finds resonance in SDG 6.
