World Water Day on 22 March, was about water and climate change – and how the two are inextricably linked. The 2020 edition of the World Water Development Report (WWDR 2020) entitled ‘Water and Climate Change’ aims at helping the water community to tackle the challenges of climate change and informing about the opportunities that improved water management offers in terms of adaptation and mitigation.
Below a few key statements pertaining to sanitation:
"Water and wastewater utilities are reportedly responsible for between 3 and 7% of GHG emissions (Trommsdorf, 2015), but these estimates do not include emissions associated with discharging untreated sewage. Indeed, untreated wastewater is an important source of GHGs. Given that, in developing countries, 80–90% of the wastewater is neither collected nor treated (Corcoran et al., 2010; WWAP, 2017), the emissions related to the water supply and sanitation sector – and its potential to contribute significantly to climate change mitigation – should not be neglected." (Page 6)
"During this century, flooding from the rising sea level and storm surges will threaten the viability of some islands as well as some major deltas, such as the Nile and Mekong River deltas (WWC, 2009). In addition to direct impacts, this will also have severe impacts on water supply and sanitation infrastructure. " (Page 7)
