Equilibrium simulation and driving factors of dissolved oxygen in a shallow eutrophic Inner Mongolian lake (UL) during open-water period (vol 22, pg 6013, 2022)

A water quality monitoring buoy installed in the center of the eutrophic shallow lake Ulansuhai was used to explore the dissolved oxygen (DO) balance. A revised DO model for shallow eutrophic lakes was applied to identify trends in the lake's DO content during the non-frozen period and determine the equilibrium relationship of DO in the water body. The coefficient of determination and the Nash efficiency of the model proved the feasibility of the model. The main drivers affecting the DO balance of the lake were photosynthesis, aeration and the lateral movements of oxygen-rich water, which accounted for 49.28, 14.72 and 36%, respectively, whereas respiration and sediment oxygen consumption, on the other hand, accounted for 1.56 and 98.44%, respectively. These findings suggest that photosynthesis and sediment oxygen consumption dominate the DO balance in eutrophic shallow lakes. A trend analysis of the average oxygen production and consumption rates indicated a maximum of 0.22 mg/L·h for photosynthesis and 0.20 mg/L·h for sediment oxygen consumption. A correlation analysis showed that water temperature was involved in changing the DO level of the lake mainly by affecting the oxygen consumption process.

During the last few decades organic matter concentrations and water colour values have increased in a large number of lakes and rivers in Eurasia and North America. The upward shift in colour, often called water browning, and shortage of mobile cations have been linked to the recovery of catchments and lakes from acid deposition and increased precipitation. Here, long-term water chemistry responses of 33 boreal forest lakes to atmospheric and catchment scale drivers were studied in a small drainage basin in southern Finland. The longest data series cover four decades starting in 1979, and thus include the period of highest acid deposition in the middle of the 1980s and its dramatic decline during the next decade. The water quality data was taken during the autumn mixing, and in this long-term data set water colour increased significantly in 23 lakes, and the most uniform increase took place in the 1990s. In lakes fed predominantly by surface-waters, colour and iron have largely behaved in parallel, both responding to the variation in hydrology with higher concentrations after wet summers. Seepage lakes, in contrast, have responded to rainy periods less noticeably. In accordance with previous studies, the results indicate that most recent changes in colour have been hydrologically driven and are lake-specific rather than consistent among the lakes. In the long-term, the base cation concentrations have declined in most lakes, resulting in electrolyte dilution, loss of alkalinity, and decreased pH. In the uppermost headwater surface water lakes, iron concentrations showed an increasing trend since 1990, but in this century the trends have been less clear. Overall, the results suggest that 25 years after the most rapid reduction in atmospheric deposition, the studied lakes are still undergoing chemical recovery. Forestry practices and beavers may have impacted on many lakes as well, complicating interpretation of the chemistry patterns caused by changes in deposition an

Failure to match national level climate action with global climate policy has moved the world to a new reality of chronic climate-induced shocks. Underlying the failure to act are policymakers’ deep-rooted mental models. In this article we present a design for an audiovisual strategic crisis dashboard that persuades policymakers cognitively and affectively to make urgent decisions to cope with long-term environmental crises. The dashboard is the product of a design experiment involving eight decision-making exercises with high-level policymakers in three Finnish cities during 2019-2022. Unlike conventional dashboards that provide information for decision-making, the strategic crisis dashboard aims to stimulate policymakers’ imagination about the long-term implications of environmental disruptions. To convince policymakers of the urgency of addressing long-term environmental crises, the dashboard transports its viewers mentally to a plausible future. The dashboard tells a narrative of complex future crises and challenges policymakers to generate a policy relevant meta-level narrative of how to cope with threatening future shocks, including concrete alternative policy measures. Strategic crisis dashboards are likely to prove increasingly important as public and private administrations at all levels prepare for future crises while responding to and recovering from ongoing ones. © 2024, The Authors.

Promoting Sustainability Value in Earth's Orbit 73

Promoting Sustainability Value in Earth's Orbit

73rd International Astronautical Congress, IAC 2022

作者： Cirkovic, Elena Rathnasabapathy, Minoo Wood, Danielle Ecosystems and Environment Research Programme Helsinki Institute for Sustainability Studies University of Helsinki Max Planck Institute Luxembourg Yliopistonkatu 3 Helsinki00101 Finland Massachusetts Institute for Technology Media Lab 75 Amherst St CambridgeMA02139 United States

This paper aims to implement an interdisciplinary approach to sustainability and protection of the orbital environment in relation to the current commercial activities. It argues that orbital and planetary sustainability, and the corresponding evolution of domestic, international, and regional regulatory instruments, need to take place in conjunction with sustainability of the Earth System, where the term "Earth system" refers to Earth's interacting physical, chemical, and biological processes. The paper focuses on interaction of complex systems to engage with important challenges that lie at the intersection of these domains. The starting point is the international outer space law, as an adaptive anthropogenic system, and its broader contextualisation in relation to Earth System and non-anthropogenic agencies. The paper then situates the role of private corporations and argues for the promotion of Sustainability Values and Corporate Social Responsibility (CSR) in outer space and the Earth System. An example of such an initiative, the Space Sustainability Rating (SSR), proposed by an interdisciplinary seeks to foster voluntary action by satellite operators to reduce the risk of space debris, on-orbit collisions, and unsustainable space operations. The paper argues for a transdisciplinary, plural, and coordinated approaches to address the environmental impact of anthropogenic activities in the outer space-Earth System interactions. © 2022 by the International Astronautical Federation (IAF).

Towards Sustainable Urban Transportation Systems – Political Agenda Formation and Windows of Opportunity in Helsinki, Oslo, and Stockholm

SSRN

SSRN 2022年

作者： Linda Emilia, Karjalainen Ecosystems and Environment Research Programme Faculty of Biological and Environmental Sciences University of Helsinki Finland University of Helsinki Finland FI-00014 Finland

This paper examines urban transportation political agenda development through the lens of sustainability in Helsinki (Finland), Oslo (Norway), and Stockholm (Sweden). The objective is to critically analyse how the global sustainability concept emerges in the local political agendas. Utilising the Multiple Streams Framework (MSF), an overview of problems, policy solutions, politics that shape the political agenda is produced. Moreover, windows of opportunity that have occurred or are currently opening are identified. The data consists of 18 semi-structured expert interviews, conducted amongst leading municipal policymakers and planners in the three Nordic capital cities, that are thematically analysed. The results reveal the importance of global climate awareness that has resulted in a strong local focus on emission reductions. Simultaneously, many social aspects are pushed to the background, even though urban attractiveness and liveability are internationally trending planning approaches. All cities push to develop cycling and walking and have established modal hierarchies – an essential step for regulating car travel. However, cars present the most politically heated debate in all case cities. This debate strongly influences the implemented sustainability measures, or lack thereof, which are dependent on the presence of strong policy entrepreneurs. © 2022, The Authors.
