Floating urbanization is a promising solution to reduce the vulnerability of cities against climate change, population growth or land scarcity. Although this type of construction introduces changes to aquatic systems, there is a lack of research studies addressing potential impacts. Water quality data collected under/near floating structures were compared with the corresponding parameters measured at the same depth at open water locations by (i) performing scans with underwater drones equipped with in situ sensors and video cameras and (ii) fixing two sets of continuous measuring in situ sensors for a period of several days/months at both positions. A total of 18 locations with different types of floating structures were considered in this study. Results show small differences in the measured parameters, such as lower dissolved oxygen concentrations or higher temperature measured underneath the floating structures. The magnitudes of these differences seem to be linked with the characteristics and type of water system. Given the wide variety and types of water bodies considered in this study, results suggest that water quality is not critically affected by the presence of the floating houses. Underwater images of biofouling and filter feeders illustrate the lively ecosystems that can emerge shortly after the construction of floating buildings.

Fresh water systems are rapidly changing and water quality is deteriorating as a result of climate change. Aquatic drones can help us understand these changes - which will be key to tackling water-related challenges ahead.The ideas presented in this article aim to inspire adaptation action – they are the views of the author and do not necessarily reflect those of the Global Center on Adaptation.

Ecocentrism is the broadest term for worldviews that recognize intrinsic value in all lifeforms and ecosystems themselves, including their abiotic components. Anthropocentrism, in contrast, values other lifeforms and ecosystems insofar as they are valuable for human well-being, preferences and interests. Herein, the authors examine the roots of ecocentrism and discuss its mixed history of international recognition. They argue that non-human nature has intrinsic value irrespective of human preferences or valuation, and they refute the claim that ecocentrism is misanthropic. They then summarize four key examples from the academic literature in which anthropocentrism fails to provide an ethic adequate for respecting and protecting planet Earth and its inhabitants. The authors conclude that ecocentrism is essential for solving our unprecedented environmental crisis, arguing its importance from four perspectives: ethical, evolutionary, spiritual and ecological. They contend that a social transformation towards ecocentrism is not only an ethical but a practical imperative, and they urge support for ecocentric understanding and practices. https://www.ecologicalcitizen.net/article.php?t=why-ecocentrism-key-pathway-sustainability https://www.linkedin.com/in/helenkopnina/

The research presented in this thesis has highlighted (bio)geochemical, hydrological, and wetland ecological processes that interact and enhance ecosystem development on wetlands built on fine sediment. A combination of greenhouse and laboratory experiments were conducted. Some measured data from these experiments formed important input for subsequent analysis in a modeling environment. The findings presented in Chapters 2-6 can be divided into four topics: 1) Plant–soil interactions in the terrestrial zone, 2) wetland–terrestrial processes influencing nutrient availability in the land–water zone, 3) effects of plants on sediment consolidation in the terrestrial zone, and 4) effects of bioturbation on nutrient availability in the aquatic zone. The next sections give a summary of the results for these four topics. The last section summarizes the recommendations formulated for the Marker Wadden project.

The concept of biodiversity, which usually serves as a shorthand to refer to the diversity of life on Earth at different levels (ecosystems, species, genes), was coined in the 1980s by conservation biologists worried over the degradation of ecosystems and the loss of species, and willing to make a case for the protection of nature – while avoiding this “politically loaded” term (Takacs, 1996). Since then, the concept has been embedded in the work of the Convention on Biological Diversity (CBD, established in 1992) and of the Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services (IPBES, aka ‘the IPCC for biodiversity’, established in 2012). While the concept has gained policy traction, it is still unclear to which extent it has captured the public imagination. Biodiversity loss has not triggered the same amount of attention or controversy as climate change globally (with some exceptions). This project, titled Prompting for biodiversity, investigates how this issue is mediated by generative visual AI, directing attention to both how ‘biodiversity’ is known and imagined by AI and to how this may shape public ideas around biodiversity loss and living with other species.

Large floating projects have the potential to overcome the challenge of land scarcity in urban areas and offer opportunities for energy and food production, or even for creating sustainable living environments. However, they influence the physical, chemical, biological and ecological characteristics of water bodies. The interaction of the floating platforms affect multiple complex aquatic processes, and the potential (negative/positive) effects are not yet fully understood. Managing entities currently struggle with lack of data and knowledge that can support adequate legislation to regulate future projects.In the Netherlands the development of small scale floating projects is already present for some years (e.g. floating houses, restaurants, houseboats), and more recently several large scale floating photovoltaic plants (FPV) have been realized. Several floating constructions in the Netherlands were considered as case-studies for a data-collection campaign.To obtain data and images from underneath floating buildings, underwater drones were equipped with cameras and sensors. The drones were used in multiple locations to scan for differences in concentrations of basic water quality parameters (e.g. dissolved oxygen, electrical conductivity, algae, light intensity) from underneath/near the floating structures, which were then compared with data from locations far from the influence of the buildings. Continuous data was also collected over several days using multi-parameter water quality sensors permanently installed under floating structures.

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

Anthropocentrism is the belief that value is human-centered and that all other beings are means to human ends. The Oxford English Dictionary defines anthropocentrism as “regarding humankind as the central or most important element of existence”. Anthropocentrism focuses on humanistic values as opposed to values found in non-human beings or ecosystems. With the popularization of the concept of ecosystem services, the idea of protecting the environment for the sake of human welfare is reflected in the SDGs. Within the SDGs, the instrumental use of the environment for the sake of alleviating poverty, combatting climate change, and addressing a range of other social and economic issues is promoted. Since the conception of the SDGs, there has been a discussion about anthropocentrism in ‘sustainable development’ (e.g., Kopnina 2016a and 2017, Strang 2017, Adelman 2018; Kotzé and French 2018) and how the SDGs can be antithetical to effective responses to sustainability challenges. The SDGs’ accent on economic growth and social equality as well as environmental protection actually result in ethical as well as practical paradoxes. While central to the SDG’s is ‘sustained and inclusive economic growth’ (UN 2015), the prioritization is on the economy, NOT the planet that nurtures both social and economic systems. Anthropocentrism, in this case, refers to the exclusive focus on short-term human benefits, whereas biodiversity loss is not considered a great moral wrong (Cafaro and Primack 2014). The three overarching anthropocentric SDG goals, economic growth, resilience, and inclusion, will be critically examined below and ways forward will be proposed. https://www.springer.com/gp/book/9783319959801 LinkedIn: https://www.linkedin.com/in/helenkopnina/
