The world is not on track to achieve SDG 6 by 2030. Some sobering statistics give a sense of the challenge:
- Billions of people still lack safe water, sanitation and handwashing facilities causing millions of deaths because of preventable diseases like diarrhea and facilitating the transmission of deadly viruses and bacteria.
- Over 80 percent of the world’s wastewater – and over 95% in some least developed countries – is released to the environment without treatment.
- The world has lost about 70 per cent of its natural wetlands over the last century.
In the past, ‘solving water’ meant providing more people access to drinking water supply and sanitation – no doubt a key element in improving people’s lives and opportunities. However, the bar was rightfully raised for SDG 6. To sustain water access, we also need to ensure that other aspects of water management – such as water governance, wastewater and water-related ecosystems – are improved. Hence, SDG 6 sets ambitious targets to achieve equitable, sustainable and efficient water and wastewater management and governance.
The water system is strongly linked to many other natural systems (e.g., vegetation, fauna, soils, climate) and human systems (e.g., food, energy, many economic sectors). Thus, achieving SDG 6 is essential for making progress in many other SDGs and vice versa. Without advancing on our water goal, it will be extremely difficult to achieve the other noble goals related to poverty, food security, gender equality, energy security, sustainable settlements, inequalities, sustainable production and consumption, climate action etc.
While there has been some progress, particularly related to water supply and sanitation, there is a growing realization that far too little has been achieved to address all targets of the comprehensive SDG 6. Thus, the question arises: Do we need to work harder and do more of the same?
Our comment in Nature Sustainability argues that more of the same is not enough. A rapid change is needed of the water economics, water engineering and water management frameworks that have guided water policy and investments so far. We need more ambitious and decisive actions along new pathways that clearly go beyond traditional approaches.
Without significant change we won’t address contemporary water challenges and, due to the central and interlinked nature of water potentially undermine efforts across the 2030 agenda. The reality is that we can’t resolve the issues of the SDGs one by one, but need to address all of them simultaneously, look at the bigger picture and manage inevitable tradeoffs. New approaches in water management can help us to move in this direction.
The predicted dramatic increases in poverty and food insecurity due to the Covid-19 pandemic and the critical role of water addressing these issues are only two of the reasons that show that we have no time to lose.
