- This paper reports on the findings of an experimental study that investigated the impact of various environmental factors on the growth of lettuce and basil plants in vertical farms. The study employed the Taguchi method, a statistical design of experiments approach, to efficiently identify the optimal growth conditions for these crops in a hyper-controlled environment. By reducing the time and cost of designing and running experiments, this method allowed for the simultaneous investigation of multiple environmental factors that affect plant growth. A total of 27 treatments were selected using the Taguchi approach, and the signal to noise ratio was calculated to predict the optimal levels of each environmental condition for maximizing basil and lettuce growth parameters. The results showed that most of the parameters, except for EC and relative humidity for certain growth parameters, were interrelated with each other. To validate the results, confirmation tests were conducted based on the predicted optimal parameters. The low error ratio between expected and predicted values (1-3%) confirmed the effectiveness of the Taguchi approach for determining the optimal environmental conditions for plant growth in vertical farms.

Planning Education and Transformative Capacity for Climate-Neutral Cities

Journal article (peer-reviewed)abstract
- To achieve their goal to become climate neutral, Swedish municipalities must significantly improve their transformative capacities. Adapting the roles and practices of urban planners is an important element in this process. This paper critically reflects on the way in which improved planning education may help to enable a new generation of planners to face the challenges of rapid urban transformation and provides them with the knowledge and tools needed for these new roles. The results suggest that there are interdependencies between the demand of municipalities for knowledge and skills and the capacity of educational programs for educating planners with transformative abilities.

Size matters : action space for sustainability transition among planners in Swedish municipalities
- 2023
-
In: Urban Research and Practice. - : Taylor & Francis. - 1753-5069 .- 1753-5077.
-
Journal article (peer-reviewed)abstract
- We analyse the action space for strategic planning and sustain-ability transition among planners in Swedish municipalities. We use qualitative and quantitative materials from 103 survey responses obtained from Swedish municipal planners. Our analysis shows that the size and type (e.g. population and density) of the municipality where the planners work are connected to their perceived action space, where policies for densely populated cities are less relevant for rural municipalities. Even if size matters for the action space for sustainability transition, this action space can be modified (e.g. access to resources and participation in networks) and continuously constructed.
