Nature-based solutions: Actions addressing societal challenges through sustainable management.

There are new or ‘emerging’ pollutants such as macro- and micro-plastics and pharmaceutical products (Geissen et al. 2015). Thus, against this landscape in constant flux with the changing nature of contaminants, the design and delivery of NBS is challenging. In 2018, The Hindu reported that the East Kolkata wetlands, the world’s largest organic sewage treatment facility, had been used to organically clean the sewage of Kolkata for several decades through the use of algae. This natural system, in use since the 1930s, was discovered by Dhrubajyoti Ghosh, an ecologist and municipal engineer in the 1970s, while he was working in the region. It had been a practice in Kolkata, one of the five largest cities in India, for the municipal authorities to pump sewage into shallow ponds .

United Nations Environment Programme and International Union for Conservation of Nature . Nature-based Solutions Policy Platform – explore how the world’s nations including nature in their climate change policy. Since 2016, the EU has supported a multi-stakeholder dialogue platform (ThinkNature) to promote the co-design, testing, and deployment of improved and innovative NBS in an integrated way. The creation of such science-policy-business-society interfaces could promote market uptake of NBS. The project is part of the EU’s Horizon 2020 Research and Innovation programme, and will run for 3 years. There are a total of 17 international partners involved, including the Technical University of Crete , the University of Helsinki and BiodivERsA. Museum Collections and Biodiversity Conservation explores how biodiversity researchers, biodiversity managers and museum curators consider the potential of museum collections to address the conservation of biodiversity, and manage climate impacts.

• However, heavily degraded urban environments can be challenging for restoration and rehabilitation (Pavao-Zuckerman 2008; Coleman et al. 2011; Fernandes & Guiomar 2018).
• Apart from that, smaller interventions usually require less coordination among diverse actors37,38,39.

We asked Garo Batmanian, Lead Environment Specialist at the World Bank, to explain. Building on the IUCN Global Standard for Nature-based SolutionsTM and its early applications, IUCN also offers stakeholders from all sectors the opportunity to earn aProfessional Certificate on NbS through the IUCN Academy. Conservation approaches and environmental management initiatives have been carried out for decades.

The IUCN defines NBS as “actions to protect, sustainably manage, and restore natural or modified ecosystems that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits” . An intervention is termed as non-NBS in this study when no aspect of working with and/or enhancing nature is found e.g. grey engineered interventions. The integration of solutions based on nature for robust policy-making has been highlighted in many sectors including transport, housing, energy and health policies, climate regulation strategies and territorial planning . Policy makers need to understand the evidence for the effectiveness of NBS co-benefits, co-harms and trade-offs across multiple policy domains. There have been several reviews looking at evidence about associations between HWB and natural environments.

We recognise it is a snapshot in time and understand that if the stakeholder consultation was repeated a different set of priority challenges may emerge. The decision to restrict the geographic scope was informed by our consultation with the stakeholders who reported that the evidence they needed for operationalising decisions relating to NBS actions should be provided in situations as socio-economically and culturally similar as possible to the UK.

The Nordic countries have different approaches to planning and implementing nature-based solutions for biodiversity, climate change adaptation and mitigation. Implementation mechanisms and guidance to different target groups may also vary across the Nordics. We therefore aim to provide a catalogue that gives an overview of the wide range of NbS projects in order to compare and share experiences among the Nordic countries. This will form a basis for knowledge sharing and development of future projects on the topic. Recently, world leaders and global organizations have increased their commitment to integrating NbS into national policies, plans, and targets based on expert analyses and evidence from practical fieldwork. Despite its multiple benefits, there are still ongoing debates about the effectiveness of NbS, especially on its standards and safeguards to avoid possible harm to people and the environment.

What You Need To Know About Nature-based Solutions To Climate Change

Later work was also dominated by studies conducted in the urban environment (77% of studies published 2012–2019). Ultimately, 115 single study articles were included in the final systematic map. Output from the CADIMA software of excluded articles with exclusion criteria is listed in Additional file 4 and coded data for all studies included in the systematic map database in Additional file 5. Nature-based solutions are ways to solve issues related to climate change or environmental deteriation that are supported and inspired by nature. Fast growing, developing cities mean there is a need to integrate NBS during planning and design, rather than retrofitting, as is frequently the case in already urbanised countries (i.e. in Europe). Retrofitting is usually more expensive and, in some cases impossible, due to a range of constraints including existing incompatible infrastructure and complex planning processes. However, in cases where NBS have been utilised, they may represent only short-term solutions, as rapid development, weak commitments and poor planning mean areas dedicated to NBS may be lost to urban development in the future.

This article reported primary data on both the economic and material living standards of people in Melbourne, Australia . Urban blue-green spaces are increasingly being degraded and lost in many Southeast and East Asian countries due to rapid rates of urbanisation. The majority of research on this topic has been conducted in high income nations where population growth rates are relatively low and stable, combined with urban development that is more regulated. Due to the speed of development and urbanisation, we believe there is a greater urgency for research on the application of NBS in countries in Southeast and East Asia in order to address its unique socio-ecological challenges.
