Climate change and the human rights to
safe drinking water and sanitation
The human rights to safe drinking water was recognized by the UN General Assembly (resolution
64/292) and the Human Rights Council (resolution 15/9). In its General Comment No. 15, the
Committee on Economic, Social and Cultural Rights clarified that the human right to water means that
everyone is entitled to sufficient, safe, acceptable, physically accessible and affordable water for
personal and domestic uses.
In its General Comment No. 15, the Committee on Economic, Social and Cultural Rights (CESCR)
outlines that “States parties should adopt comprehensive and integrated strategies and programmes
to ensure that there is sufficient and safe water for present and future generations”, including by
“assessing the impacts of actions that may impinge upon water availability and natural-ecosystems
watersheds, such as climate changes, desertification and increased soil salinity, deforestation and loss
of biodiversity”.
In 2010, the Independent Expert on the human right to water and sanitation, Catarina de
Albuquerque, wrote a position paper highlighting the impacts of climate change on the normative
content of the human rights to water and sanitation. Her findings are summarized below:
Explanation of normative content
Impact of climate change
Availability holds that the water supply for each person
must be sufficient and continuous for personal and
domestic uses. These uses ordinarily include drinking,
sanitation, washing of clothes, food preparation,
personal and household hygiene.
Water availability will be threatened by
increased water scarcity and competition
for resources.
Quality means that the water required for each
personal or domestic use must be safe and free from
contaminants that threaten health. Water should be of
an acceptable colour, odour and taste for each personal
or domestic use.
Water quality will decline through
overexploitation of groundwater and
increased concentration of pollutants.
Accessibility means water facilities and services have to
be accessible to everyone without discrimination.
Accessibility has four overlapping dimensions: physical
accesibility, economic accessibility, non-discrimination,
and information accessibility.
The accessibility of water and sanitation
services will be threatened through
widespread damage and infrastructure
due to flooding and extreme events.
Affordability means that access to sanitation facilities
and services, including construction, emptying and
maintenance, must be available at a price that is
affordable for all people without limiting their capacity to
access other human rights.
The affordability of water services may
decline as increased competition between
uses of water leads to rising costs.
Acceptability means that water and sanitation services
must be culturally acceptable. This includes that they
should be safe, and ensure privacy and dignity.
Under increasing stress, it is likely that the
cultural acceptability of water and
sanitation services is not prioritized and is
in some cases ignored.
