Welcome

Despite the challenges of COVID-19, the climate and biodiversity crises are ongoing. Transformative action to address these interrelated crises is needed now more than ever. To this end, on 7-9 July 2020 the Nature-based Solutions Initiative hosted a virtual event, NbS Digital Dialogues, to discuss each of four key guidelines for successful, sustainable nature-based solutions (NbS) outlined in www.nbsguidelines.info. Over 750 people registered from across the globe and tuned into a series of keynotes, panel discussions and poster sessions in which we debated the main challenges around the implementation, financing and governance of NbS, and how to overcome them. We also reflected on the role of NbS for economic recovery from COVID-19 across the world.

NbS Digital Dialogues served as a primer to the Nature-based Solutions Conference, now postponed to July 2021, with many of our speakers for the 2021 conference contributing to this virtual event as well.

What’s next? You can find recordings of all the sessions here and below. We will soon provide written summaries of key messages and post them here. The posters from the event can be downloaded from the galleries below. To keep up to date with the Nature-based Solutions Initiative, including news on the upcoming conference in 2021, you can sign up to our newsletter via our main website.

Programme

The event comprised three keynotes and six 75-minute panel sessions over three days. Sessions involved 4-5 short presentations, a facilitated panel discussion, Q&A sessions with our remote audience, and poster sessions. Our facilitators and speakers were world-leading experts from across science, policy and practice working at the nexus of climate change, biodiversity and development.

Session 01 7th July

NbS for climate change mitigation

Guiding principle 01: NbS are not a substitute for a rapid fossil fuel phase-out and must not delay urgent action to decarbonise our economies

Nature-based solutions for climate change mitigation are currently in the limelight, but uncertainties on the potential contribution of NbS to tackling climate change and serious concerns about trade-offs and unintended consequences remain. In this session, we discussed current understanding of the mitigation potential of NbS, highlighting their role in reducing peak warming and enabling long term cooling. We then discussed major issues around scaling up bioenergy, BECCS, intensifying agriculture, and afforestation including inappropriate tree-planting on naturally open ecosystems such as grasslands, savannas, and peatlands. Finally, we debated the moral hazard of promoting NbS at the expense of delaying fossil fuel emissions reductions.

We asked: Is biological offsetting of carbon emissions good or bad?

NbS in all ecosystems

Guiding principle 02: Successful, sustainable NbS involve the protection and/or restoration of a wide range of naturally occurring ecosystems on land and in the sea, not only forests

Currently, high-level multilateral pledges for nature focus on forests. In this session, we will highlight how other ecosystems provide important carbon storage services, help society adapt to climate change, are rich in biodiversity, and support the livelihoods of millions of people. We highlighted the vital role of drylands, freshwater, coastal and marine habitats in storing carbon and shielding humans from climate change impacts and promoting resilient landscapes that support livelihoods. In particular, we focused on how this knowledge can be harnessed in a landscape planning context to prioritize nature-based solutions.

We asked: How should ecosystems be prioritised for restoration and protection? Who should decide/or/through what modes of governance should these decisions be made?

NbS with, by and for people

Guiding principle 03: Successful, sustainable NbS are implemented with engagement and consent of Indigenous Peoples and local communities, apply robust social safeguards, and are designed to build human capacity to adapt to climate change

What makes the NbS framing different and powerful? The answer is people. In this session, we will discuss how Indigenous Peoples and local communities drive transformative NbS. With reference to diverse examples from across the globe, we discussed why local knowledge and engagement, leadership and collective action are central to nature-based solutions for climate change and highlighted the importance of recognising, respecting and upholding people’s livelihoods and rights.

We asked: How can Indigenous Peoples and local communities be empowered to engage with other stakeholders and drive the delivery of NbS? What structures enable such agency to emerge?

Biodiversity and NbS

Guiding principle 04: Successful, sustainable NbS sustain, enhance or support biodiversity

Biodiversity plays a vital role in the healthy functioning and resilience of ecosystems. It secures the flow of essential services, reduces trade-offs among them, and supports human capacity to adapt to climate change. In this session, we highlighted the contribution of biodiversity to climate mitigation and/or adaptation in the context of protecting intact ecosystems, restoring landscapes and sustaining agriculture. Then we discussed how knowledge of biodiversity’s importance could better inform the policy and practice of NbS. We will discuss interlinkages between the CBD’s Global Biodiversity Framework and the UNFCCC’s Paris Agreement and reflected on how best to overcome key obstacles to biodiversity-based policy targets.

We asked: as we take NbS to scale, how do we ensure that they support biodiversity and are resilient in a rapidly changing world?

Financing NbS

Overcoming obstacles and mobilizing investments for successful, sustainable NbS

To mobilize large and sustainable flows of finance to nature-based solutions we need to break out of existing paradigms. In this session, we discussed what this paradigm-shift looks like across companies and industries, financial institutions, private investors, governments, multilateral agencies and the global community.

We asked: what role can and should nature-based solutions play in enabling a green recovery post-Covid19?

Governing NbS

Overcoming the governance challenges of taking Nature-based Solutions to scale

Nature-based solutions depend on innovative and effective governance at local, national, and transnational scales. In this session, we will compare the successes and challenges in the governance of nature-based solutions across a diverse array of countries facing different challenges for sustainable development and we will explore which models can be replicated and scaled up. Looking ahead to the CBD COP15 and UNFCCC COP26 in Glasgow in 2021, we discussed what we can learn from these experiences to further catalyse and scale-up effective NbS.

We asked:  What are some key innovations or successes in NbS governance? What can COP26 and/or COP15 do to support success at the national level?
