A thriving,
biodiverse Bulb region

The world-famous Bulb region is a national pride and of great value to the Dutch economy. What about the future of the region? The central question in this project is: what is needed to achieve a transition to a circular economy, better health, more sustainable use of raw materials, and higher quality of working and living environment with more nature and biodiversity? Facilitated by Naturalis Biodiversity Center, entrepreneurs, researchers and policymakers from and around floriculture are committed to a thriving, biodiverse Bulb region.

A new way
of collaboration

The project is set up to collaborate based on the demand of bulb growers, other entrepreneurs and industry organizations on a future-proof Bulb region, nature-inclusive, liveable and economically attractive.

The bulb growing sector includes many parties such as entrepreneurs from within and outside the sector, industry associations, governments, social organizations and research institutes. The role of Naturalis's team 'NL Biodiversity & Society' in this project, in collaboration with Erasmus University Rotterdam, is to facilitate this process of innovative collaboration.

and ambitions

The products delivered by the project are directly in line with the challenges faced by entrepreneurs and other stakeholders in practice. In the form of KICK vouchers (Knowledge and Innovation for Circular Economy and Cycles), the parties involved collaborate to quickly find answers to knowledge questions from entrepreneurs. In addition, the parties collaborate to make knowledge user-friendly (knowledge mobilization), divided over the three topics:

  • Circular cultivation and chain: Research into the possibilities for a Biodiversity Monitor for the Bulb region - Naturalis, Leiden University, NIOO-KNAW
  • Liveable region: Inventory of the roles that parties in the Bulb region can play in a circular bulb cultivation - Erasmus University
  • Natural capital: Development of a decision-making tool and area approach -  Institute of Environmental Sciences (CML), Leiden University and Erasmus University

In this way, a contribution is made to the flourishing of the Bulb region in the future, in line with the long-term ambitions of the Bulb region.
