Abstract [en]

Cypriot development is highly dependent on fossil fuel imports for supporting country production levels to meet the local demand.  With the island’s entry in the European Union, a long term strategy for converging the unsustainable development with sustainable development is necessary.  In our attempt to assess Cyprus sustainability, several factors that affect the system have been observed.  The most significant environmental impacts are drought, water pollution, erosion and wildlife preservation. The uneven precipitation levels and absence of natural reservoir catchments have striking effects on soil quality and life. The purity of the water supply is threatened by industrial pollutants, the lack of adequate sewage treatment and pesticides used in agricultural areas. The environmental load becomes a debt in the national liabilities.  Adding to the complexity, the effect of tourism poses more risks on the local communities. Resource availability and resource scarcity are a global concern. How, then, can models help in the assessment of Cyprus sustainability? Integrated assessment models – integrating e.g. geographic information, populations statistics, and environmental load – illustrate the interconnected relationships and limits of the socio-natural system and the biosphere.  For example, the albedo effect in the future under different assumptions can be estimated. Assumptions can be made regarding e.g. Cyprus future population, economic growth and indigenous resource availability.  The general ecologic view on global resource availability is that the Earth is finite.  Models like the “The Limits to Growth”, by Meadows et al. (1972) and “The Pulsing Paradigm” by Odum et al. (1995) represent the striking events of fossil fuel-based societies. Models can also be manipulatied in the quest for a high output/input ratio than in reality.  The ability to use modeling knowledge and facilitate decisions before the implementation stage helps avoiding crisis and system collapse.

Abstract [en]

Emergy analysis (emergy synthesis) is one of the methods in the sustainability assessment toolbox. In the way it is using stocks and flows of energy and matter it is similar to Life Cycle Assessment (LCA), Material Flow Analysis (MFA) and Substance Flow Analysis (SFA). However, Emergy accounting also includes stocks and flows of money and information. In its mechanism of relating to a global baseline of renewable flows Emergy accounting is similar to Ecological footprints in that it is not just revealing which of two alternatives is using more or less of different stocks or flows but also comparing the use to available renewable flows on a global annual basis.

This paper address the contribution of four different aspects of Emergy analysis, to the overarching goal of sustainability from a modelling perspective.

The four different approaches of assessing sustainability identified are: 1) the Emergy Sustainability Index (ESI), 2) emergy as a normalizing measure, 3) emergy as a network measure, and 4) the pulsing paradigm.

Abstract [en]

This paper, inspired by Sven Erik Jørgensen's academic life, takes a systems ecology perspective on sustainability in wastewater sludge management. First, an overview identifies the indicators and methods currently used to assess sustainability and sustainable development in the area of wastewater sludge. Second, two systems ecology conceptual models are presented. Third, the indicators and methods are discussed in the perspective of these systems ecology models. Four methods were found common in assessing wastewater sludge sustainability: Life Cycle Assessment (LCA), Exergy Analysis (ExA), Emergy Analysis (EmA), and Cost Benefit Analysis (CBA). Environmental Risk Assessment (ERA) was added since it was found to be used in the larger wastewater treatment context, and complements the other four methods. When comparing the indicators and methods with the systems ecology models it was found that no method covered every aspect of the models. ExA, EmA and ERA covered the full extent of the models but not from every aspect interesting from a sustainability point of view. LCA and CBA had a lower reach at the ecosystem side of the models, but produced deeper knowledge regarding environmental impacts for LCA, and economic flows and storages for CBA. The investigation concludes that a complementary approach of methods and indicators is needed to assess sustainability, and they are suggested to be used in an integrated way, in the spirit of Sven Erik Jørgensen's findings.

Abstract [en]

Environmental Science aims to study the relationships between human beings influence on and dependence of nature, the interaction and integration of ecological, social and technical systems as well as the strategies for sustainable use of natural resources. The linking of social, ecological and economical aspects in Environmental Science can provide useful tools for the study, management and conservation of freshwater crayfish from a broad social perspective. Therefore, it is of interest to explore the relationships between Environmental Science and Astacology. By analysing the aims of the International Association of Astacology and the content of some volumes of Freshwater Crayfish from an Environmental Science perspective we found that Astacology is operating within the field of Environmental Science. The focus is mainly on identifying underlying mechanisms of environmental issues. We will point out unexplored scientific perspectives and propose some advice of how to study freshwater crayfish from a broad systems perspective.
