Double Nature Summit
Planning for regeneration and natural
carbon restoration at scale
May 22-25, 2023
Co-organized by






4 days of collective inspiration and action to double nature
The Double Nature Summit is a 4-day participatory platform bringing together a diverse range of stakeholders, including regenerative pioneers, investors, scientists, businesses, policymakers, non-governmental organizations, indigenous people, and local communities. Based on Paul Hawken’s Drawdown and Regeneration, and many others, our common goal is to double nature – applying regenerative practices to re-store carbon dioxide in the land and oceans. We think this can be done best with entrepreneurial drive and distributed scaling and we work towards a regenerative economy with which we can live in fairly distributed prosperity within planetary boundaries.
Learn about current ecosystem challenges, get inspired by pioneers and innovations, exchange knowledge and expertise, grow collaborations, and contribute to the design of new initiatives that help nature grow twice as big and strong. Join the community of regenerators!
Who were there

Domain-Specific Conferences (May 22 – 24)
Each year, the Double Nature Summit aims to drive action across all possible domains of nature based solutions: on land, in the oceans, via rock weathering and with bio-based construction. Participate in one of the Domain-Specific Conferences to:
- Network with fellow pioneers, get up to date with recent practices and scientific findings and share expertise.
- Gain an in-depth understanding of current barriers to scaling nature-based solutions within your sector, and work towards solutions together.
- Understand what business cases we can base ourselves on to implement nature-based solutions and double nature.
Insights from these days will feed into the Double Nature Day. Each domain has its unique program. Read more on the Sector-Specific Conferences below.
The Double Nature Day: Connection, Integration, Action (May 25)
Join the Double Nature Day, uniting all the domains and beyond. Get a comprehensive overview of the state of the regenerative economy with reports from the domain-specific conferences and keynotes. Gain skills and knowledge in in-depth workshops focused on your role in the system and work towards implementation in act-shops. Connect and network with your fellow regenerators – pioneers, entrepreneurs, investors, policymakers, and all the other change agents.

How can storytelling help to Double Nature? How do we tell that story? To whom? At what places? –Session in Dutch
@ Jeppe van Pruissen (Change the Story)
CREATING SELF GOVERNING COMMUNITIES
Many great initiatives have come to fruition because of one driving force, a visionary, entrepreneur… you name it. Yet when they step down the project windels down. By introducing the case study of Utopia Eiland we will discuss and investigate what is needed to create a self governing community which can move forward even when the instigator steps down.
@ Xavier San Giorgi (Stichting Weerwoud)
REGENERATIVE FINANCE AND THE GOVERNANCE LADDER

How can we see, think and act in a way that respects and builds on the potential of the places we live in, while benefiting social and ecological systems? Through a series of Actshops, participants have the opportunity to collaborate on specific case studies provided by enterprises, aided by principles of regenerative community design. You can choose to work with one case study.
@Josine Bakkes (Architects of Communities)
CO-CREATING THE COMMONS
Voedselpark Amsterdam is an alternative to the outdated plans for a distribution center on the last fertile soil of Amsterdam. They aim to create an ecological living lab and regenerative food hub on 60 hectares, on the edge of Amsterdam.
Challenge: How might we create a commons mindset in politics and municipal governments?
@ Natacha Hulst (Voedselpark Amsterdam)
@Bonnie Chopard
(Inlandschap)
DOUBLE NATURE AND MANGROVES
Bonaire hosts the largest mangrove forest within all of the Dutch Caribbean. These forests provide immense biological, economical and cultural value to the island.
Challenge: How might we restore mangrove forests and the communities around them to preserve one of the most important and threatened ecosystems on the planet?
@ Eelco Leemans (Climate Cleanup) @ Sabine Engel (Stinapa)
BIO-BASED BUILDINGS STORE CARBON, SOCIAL AND DISTRIBUTED
Easy Housing co-creates circular-, regenerative and disaster-resilient homes in collaboration with communities in the Global South.
Challenge: How might we scale up our housing technology service through inclusive home financing and carbon credits?
@Niels van den Berge (Easy Housing)
WEAVING THE TRIBES OF EUROPE AND TURTLE ISLAND
Lyla’s doctoral research focused on exploring the ways in which pre-colonial Indigenous Nations shaped large regions of Turtle Island to produce abundant food systems for humans and non-humans.
Challenge: How might we weave together indigenous nations across turtle island and Europe?
@ Lyla June Johnston (Lyla June)
LIFETIME CARBON CLEANUP
All of us have benefitted from the use of fossil fuels. However, we now know this has enormous consequences for our planet.
There are changemakers they however are not being financed. How can we pay them for the service of cleaning up the climate and double nature?
Challenge: How can we make cleaning up lifetime emissions using nature-based carbon removal as normal as health care?
@ Bart van Beuzekom (Scave.World)
THE FUTURE MACHINE
The Future Machine is an exhibition showcasing the miracles of people, nature, and technology. An immersive meeting place for innovators, entrepreneurs, and creators. Right here at Tolhuistuin.
Challenge: How might we find business partners who want to showcase their work and co-create the Future Machine?
@Matthea de Jong (Tolhuistuin)
BE AN OCEAN FARMER
Current developments within seaweed farming, are opening up a whole new industry of low trophic oceanic agriculture. An immense potential for the good of the planet.
Challenge: How might we roll-out the oceanic agriculture industry, so that it maximizes positive impact, while also distributing its profit to as many people as possible?
@Alexander Ebbing (Hortimare)
RESTORE LANDSCAPES VIA LOING TERM PROCESS FUNDING
Commonland works all over the globe with a diverse range of partners to protect and restore landscapes and to build sustainable business cases which generate an income for local communities.
To be successful, landscape restoration takes 20 years. This means that Commonland focuses on funders who are willing to commit themselves for a longer period to fund local organizations, offices, and other overhead costs vs funders who are only interested in short-term projects and results.
Challenge: How can we act together to shift funder’s preference from short term project to long term process funding?
@Mariken van den Boogaard (Commonland)
@Eva Cappon (Commonland)
17:00 Launching “Pathways to Double Nature Plan”
Double Nature Actions, the DNA of our plan, are place-based, regenerative and systemic actions that contribute to doubling nature. Double Nature is a radically positive plan to reverse climate change. It is not about doing less, but about doing more. It brings health, restores carbon and regenerates life.

RESTORE LANDSCAPES VIA LOING TERM PROCESS FUNDING
Commonland works all over the globe with a diverse range of partners to protect and restore landscapes and to build sustainable business cases which generate an income for local communities.
To be successful, landscape restoration takes 20 years. This means that Commonland focuses on funders who are willing to commit themselves for a longer period to fund local organizations, offices, and other overhead costs vs funders who are only interested in short-term projects and results.
Challenge: How can we act together to shift funder’s preference from short term project to long term process funding?

17:00 Launching “Pathways to Double Nature Plan”
Double Nature Actions, the DNA of our plan, are place-based, regenerative and systemic actions that contribute to doubling nature. Double Nature is a radically positive plan to reverse climate change. It is not about doing less, but about doing more. It brings health, restores carbon and regenerates life.
