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.
Successful Food-energy-water (FEW) nexus projects will be more likely to succeed if a transdisciplinary approach is used. Ecological modernization (ecological technology) policies and practices, and sustainable supply chains influence the FEW nexus from a commerce and industry perspective. Taking these perspectives and considering their intertwined linkages is important for advancing research and adoption of FEW nexus efforts. This paper provides an overview of these perspectives and interlinkages.
Recent research and professional interest in planning for sustainable and resilient cities emphasizes the assessment of a broad spectrum of urban ecosystem services. While such assessments are useful to establish specific benchmarks, and for measuring progress toward sustainability and resilience goals, they do not motivate, or support the innovations required to provide specific ecosystem services as an intentional part of routine urban and infrastructure development activity by municipalities and professionals.
