‘Non art is more art than art art’, Allan Kaprow claimed in 1972. He concluded: ‘Artists of the world, drop out! You have nothing to lose but your professions.’ Are we ready to move on? From the 6th until the 9th of June 2024, an international group of art workers gathered at Floating Berlin to explore this question during the Konteksty Postartistic Congress.

The rapid implementation of large scale floating solar panels has consequences to water quality and local ecosystems. Environmental impacts depend on the dimensions, design and proportions of the system in relation to the size of the surface water, as well as the characteristics of the water system (currents, tidal effects) and climatic conditions. There is often no time (and budget) for thorough research into these effects on ecology and water quality. A few studies have addressed the potential impacts of floating solar panels, but often rely on models without validation with in situ data. In this work, water quality sensors continuously monitored key water quality parameters at two different locations: (i) underneath a floating solar park; (ii) at a reference location positioned in open water. An underwater drone was used to obtain vertical profiles of water quality and to collect underwater images. The results showed little differences in the measured key water quality parameters below the solar panels. The temperature at the upper layers of water was lower under the solar panels, and there were less detected temperature fluctuations. A biofouling layer on the floating structure was visible in the underwater images a few months after the construction of the park
Urban delta areas require innovative and adaptive urban developments to face problems related with land scarcity and impacts of climate change and flooding. Floating structures offer the flexibility and multi-functionality required to efficiently face these challenges and demands. The impact of these structures on the environment, however, is currently unknown and research on this topic is often disregarded. This knowledge gap creates a difficulty for water authorities and municipalities to create a policy framework, and to regulate and facilitate the development of new projects.Monitoring the effects of floating structures on water quality and ecology has been difficult until now because of the poor accessibility of the water body underneath the structures. In this work, a remote controlled underwater drone equipped with water quality sensors and a video camera was used to monitor dissolved oxygen near and under floating structures. The collected data showed that most water quality parameters remain at acceptable levels, indicating that the current small scale floating structures do not have a significant influence on water quality. The underwater footage revealed the existence of a dynamic and diverse aquatic habitat in the vicinity of these structures, showing that floating structures can have a positive effect on the aquatic environment. Future floating structures projects therefore should be encouraged to proceed.
HZ University of Applied Sciences (HZ) together with Dutch SME’s Recycled Island Foundation and Upp! Upcycling Plastic will be executing a feasibility study into the most efficient and effective collection system of floating macro-plastics in the Mekong delta in Vietnam (floating passive litter traps, litter fishing, or other). All three project partners are (separately) already active in The Netherlands, Belgium, Indonesia and Vietnam in the field of environmental (practice based) research and development (among others in Living Lab settings with local universities and communities). This project aims at expanding cooperation between all three project partners including partners’ partners in the living lab network in Vietnam. The results of the feasibility study enables the research group Building with Nature of HZ acquiring experience in and expertise of a possible new research topic “reducing macro-plastics in water systems and re-using it in an effective and efficient manner”. Moreover, the results of the project will enable both SME to expand their export opportunities and business to Asian countries, which severely suffer from increasing plastic waste.
