Edible City Solutions for a better world!

Second Diamond Model Workshop in Rotterdam Helps Green Urban Food Initiatives Identify, Visualise & Strengthen Their Core Values

The latest EdiCitNet Diamond Model workshop in Rotterdam was full of inspiring discussions and vivid collaboration.

On the afternoon of May 10, 2022, eight representatives from different Edible City Solution Initiatives in

Rotterdam and two representatives of the City of Rotterdam came together at the green initiative Stadskwekerij De Kas for a Diamond Model workshop, based on the Diamond Model concept developed as part of the EdiCitNet Marketplace. The diamond model tool can be used by urban food initiatives to help them gain a new perspectiveidentify their core values and develop strategies that will ensure the initiatives stay strong, stable and thriving long into the future. The Diamond Model can also help you learn how to communicate effectively about how, why and to whom your organisation makes a difference.


Similar to the Business Model Canvas, the Diamond Model supports business model innovation and strategising. But it’s not just for profit-oriented organisations – it can be used to support all types, including NGOs, NPOs and associations too.

This workshop was the follow-up of the previous Diamond Model workshop held in April 2022 . After a short introduction to the model, participants crafted their own diamonds representing the positive values created by their respective initiatives. Then three value loop analyses were carried out, taking examples from the challenges that different initiatives are facing.

This workshop was initiated by Groen010s local working group “Visibility and Values of Green Initiatives” with Nienke Bouwhuis (Groen010/Groene Connectie), Paul De Graaf (Groen010/Coöperatie Ondergrond) and Alice Bischof (Wageningen University) who worked to organise the workshop together.

New EdiCitNet Publication: “Let’s Do It Online!? Challenges and Lessons for Inclusive Virtual Participation

The latest EdiCitNet publication explores the ongoing challenges of digital equity and the affects of the pandemic on participatory planning processes.

The Covid-19 pandemic has had a huge impact on the participatory planning process in the Edible Cities Network project, in particular the work with the project’s Follower Cities (Berlin, Carthage, Guangzhou, Lomé, Montevideo, Sant Feliu and Sempeter pri Gorici) who are working – mostly online – to develop Edible City Masterplans. The project partners involved in this work have been assessing this impact in order to learn from the pandemic – about what can be done to make digital processes more effective and identify what challenges occur.

With this paper, published in Frontiers in Sustainable Food Systems, the EdiCitNet Follower Cities provided insights into their disrupted workflow and helped the project to better understand the difficulties in each city during the pandemic. Additionally, the reflections in this paper offer learnings from the disruptions caused by Covid-19 to better understand how participatory planning processes can be managed online along the lines of equity, access, and participation. The findings demonstrate how participatory processes in the ongoing crisis can be maintained, with relevance to future waves of this and other pandemics.

Under the slogan “Economy meets science”, the annual event “BuGG Day of Research and Education” took place in Stuttgart on the 10th of May 2022, organized by the German Federation for Building Greening (Bunderverband Gebäudegrün – BuGG).


In attendance were all universities and research institutions active in the fields of roof, façade and interior greening, as well as BuGG members and other building greening experts.

The aims of the “Building Greening Research and Education Day” are:

– To present current research projects

– To identify further research needs

– To network and get to know each other

– To exchange experiences across disciplines

The BuGG Research and Education Day was divided into two parts this year. In the first part (mainly in the morning), the participating universities and research institutions had the opportunity to give short presentations about themselves and their university or institution with their current research and funding projects. Rebecca Gohlke from BuGG presented the EdiCitNet project to the almost 100 participants.

After the lunch break in the second part, there was the opportunity to casually network, get to know each other and exchange ideas.
