Recent policy developments in Europe consider the importance of water ecosystems to human wellbeing and the detrimental effects that multiple pressures may have on them. Several directives and measures which culminated with the design and the implementation of the Water Framework Directive, have attempted to address the issue of sustainable water management while aligning with targets of economic development.

Cities are wrestling with the practical challenges of transitioning urban water services to become water sensitive; capable of enhancing liveability, sustainability, resilience and productivity in the face of climate change, rapid urbanisation, degraded ecosystems and ageing infrastructure. Indicators can be valuable for guiding actions for improvement, but there is not yet an established index that measures the full suite of attributes that constitute water sensitive performance.

Urbanisation is increasing in many countries, leading to the establishment of 33 megacities, representing huge water demand which is increasingly difficult to supply, exemplified by the recently avoided Day Zero event in Cape Town (2018) and the ongoing water crisis in Chennai, India. The ongoing growth of megacities could lead to the potential for further Day Zero events in countries ill-equipped to deal with such a situation. This study analyses the water supply and demand situations in 12 megacities hosting 194 million people.

Soil and water salinity and associated problems are a major challenge for global food production. Strategies to cope with salinity include a better understanding of the impacts of temporal and spatial dynamics of salinity on soil water balances vis-à-vis evapotranspiration (ET) and devising optimal irrigation schedules and efficient methods. Both steady state and transient models are now available for predicting salinity effects on reduction of crop growth and means for its optimization.

Water–Sanitation–Hygiene (WASH) remains vital for the 2030 Agenda for Sustainable Development, yet many countries have not localised the 17 Sustainable Development Goals (SDGs), including SDG 6, which focuses on ensuring the availability and sustainable management of water and sanitation for all. Even in leading African economies such as South Africa, many communities still use the bucket system for sanitation.

Using a consumption-based Multi-Regional Input-Output (MRIO) model, we investigate the distinctive characteristics, self-efficiency or external dependency, of energy demand's water footprint in China's two biggest and fastest developing megalopolises. We find that energy demand water footprint in the Jing-Jin-Ji and the Yangtze Delta amounted to 2.41 and 9.59 billion m³of water withdrawal respectively in 2010, of which 848.06 and 973.91 million m³was consumed. Among all energy products, electricity contributed the largest share to the energy sector's water footprint in both regions.

This study supports SDGs 3 and 6 by showing that elementary WASH interventions alone were insufficient in reducing the prevalence of stunting, anaemia, and diarrhoea in children in rural Zimbabwe; these findings call for greater investment into, and scale-up of, WASH programmes in rural settings, in order to achieve more meaningful improvements in child health outcomes.
