The benefits of Nature Based Systems in a changing and uncertain world
Multi-functional nature-based solutions (NBS) can help urban areas become more climate proof, adaptable, and provide a range of societal goals. Alongside chronic impacts from climate change, the Covid-19 pandemic has illustrated the disruption that unexpected and acute shocks can bring to society. Measures like NBS can help reduce the vulnerability of urban areas and increase resilience. Traditional infrastructure planning relies on strong business cases to demonstrate the economic value of a scheme. Numerous approaches assign economic value to the benefits from using NBS. However, this value is more than can be accounted by traditional finance methods as there are many different perspectives on ‘value’. Decision making processes for selection of NBS measures require stronger integration of these value perspectives. This paper considers these perspectives in the business models that are being used in the decision processes regarding use and selection of NBS. Examples are drawn from case studies in the EU BEGIN project and also from the Living With Water (LWW) partnership in the UK illustrate how value perspectives can be included in business cases for NBS, also signposting the need to account for potential future changes using scenario planning.
期刊介绍:
Engineering Sustainability provides a forum for sharing the latest thinking from research and practice, and increasingly is presenting the ''how to'' of engineering a resilient future. The journal features refereed papers and shorter articles relating to the pursuit and implementation of sustainability principles through engineering planning, design and application. The tensions between and integration of social, economic and environmental considerations within such schemes are of particular relevance. Methodologies for assessing sustainability, policy issues, education and corporate responsibility will also be included. The aims will be met primarily by providing papers and briefing notes (including case histories and best practice guidance) of use to decision-makers, practitioners, researchers and students.
