Energy sustainability indicators for urban environments

Sustainable development comprises of three dimensions. The three dimensions are the environment, the social and the economic. There have been many indicators used to measure the three dimensions of sustainability. For example air pollution, consumption of natural resources, quality of open space, noise, equity and opportunities and economic benefits from transport and land use. Urban areas constitute the most crucial factor in the sustainability. Urban systems affect and are affected by natural systems beyond their physical boundaries and in general the interdependence between the urban system and the regional and global environment is not reflected in urban decision making. The use of energy in the urban system constitutes the major element in the construction and function of urban areas. Energy impacts across the boundaries of the three dimensions of sustainability. The objective of this research is to apply energy-use-indicators to the urban system as a measure of sustainability. This methodology is applied to a case study in the United Kingdom.

Sustainability indicators and local governance in Portugal

Esta tese tem como principal objectivo compreender o papel dos indicadores de sustentabilidade na governação local em Portugal, bem como perceber o seu potencial para transformar práticas institucionais correntes para o desenvolvimento sustentável. As duas últimas décadas têm testemunhado um crescente debate em torno dos indicadores de sustentabilidade e três abordagens específicas da literatura ganharam corpo: a ‘técnica’, a ‘participativa’ e a de ‘governação’. Esta tese pretende contribuir para a abordagem mais recente e menos explorada da ‘governação’, através do estudo da realidade local portuguesa. Considera crucial perceber como e em que circunstâncias e contextos o papel destes indicadores pode ser diminuído ou potenciado. Desta forma, pretende avaliar se e de que forma é que os indicadores de sustentabilidade têm contribuído para alterar e desafiar contextos de governação locais para o desenvolvimento sustentável no nosso país e se e de que forma estes indicadores têm sido usados. Foram seleccionados e analisados em detalhe sete casos-de-estudo na tentativa de compreender cada um e de construir uma grelha comparativa entre eles utilizando como suporte normativo um conjunto de critérios ‘ideais’ de boa governação. Assim, a tese identifica os principais obstáculos da construção destes indicadores em Portugal, bem como os seus principais contributos positivos e usos. Enquadra igualmente as suas conclusões no contexto de outras experiências locais Europeias e tenta formular algumas recomendações para reforçar o potencial contributo e a utilização destes indicadores. Através dos casos-de-estudo, foi possível verificar que a sua implementação não tem contribuído para fortalecer o diálogo entre os diferentes níveis de governo, para promover a participação de mais actores nas redes de governação, ou mesmo para melhorar mecanismos de participação e comunicação entre governos, cidadãos e actores locais. De qualquer forma, é importante acrescentar que as experiências mais bem sucedidas permitiram efectivamente mudar as capacidades dos governos locais na coordenação horizontal de políticas sectoriais, nomeadamente através de novas relações entre departamentos, novas rotinas de trabalho, novas culturas de recolha e tratamento de dados locais, novos estímulos de aprendizagem, entre muitas outras. O maior desafio coloca-se agora na transposição destes efeitos positivos para fora da esfera governamental. Esperamos que a tese possa contribuir para que decisores políticos, técnicos, académicos e comunidades locais encarem os indicadores de sustentabilidade como processos de aprendizagem que melhoram a capacidade das cidades enfrentarem os complexos desafios e as incertezas do desenvolvimento sustentável.

Linking sustainability indicators of Indian wild caught ornamental fish industry

The Indian ornamental fish industry is divided into two- the domestic market and the export market. 90% of the freshwater ornamental fish exported from India are wild caught indigenous species. The study formed the criteria and indicators assessing the sustainability of wild caught ornamental fish exported from India. These indicators were then analyzed for their interactions, connections, linkages and relationships using cognitive mapping. The work is first of its kind in the ornamental fisheries

Experiences with sustainability indicators and stakeholder participation: A case study relating to a 'Blue Plan' project in Malta

The practical application of systemic sustainability analysis (SSA; Bell and Morse, 1999) as applied in-a project instigated and managed by 'Blue Plan', one of the regional activity centres of the Mediterranean Action Plan, is set out and explained in this paper. The context in which SSA was applied and adapted to SPSA (systemic and prospective sustainability analysis). is described in the Mediterranean, primarily in Malta. The SSA process is summarized, its extension and linkage to the prospective approach is described and the comments of stakeholders in the context are added. Some preliminary outcomes are suggested. The pauticular focus of the paper is on the lessons learned from doing SSA/SPSA within a classic blueprint project framework. It is-not assumed that SSA/SPSA is 'finished' or 'definitive'. Rather, we suggest that it is a developing and changing approach that practitioners can adapt and change to meet the specific needs of the circumstances that confront them.

Integrating methods for developing sustainability indicators that can facilitate learning and action

Bossel's (2001) systems-based approach for deriving comprehensive indicator sets provides one of the most holistic frameworks for developing sustainability indicators. It ensures that indicators cover all important aspects of system viability, performance, and sustainability, and recognizes that a system cannot be assessed in isolation from the systems upon which it depends and which in turn depend upon it. In this reply, we show how Bossel's approach is part of a wider convergence toward integrating participatory and reductionist approaches to measure progress toward sustainable development. However, we also show that further integration of these approaches may be able to improve the accuracy and reliability of indicators to better stimulate community learning and action. Only through active community involvement can indicators facilitate progress toward sustainable development goals. To engage communities effectively in the application of indicators, these communities must be actively involved in developing, and even in proposing, indicators. The accuracy, reliability, and sensitivity of the indicators derived from local communities can be ensured through an iterative process of empirical and community evaluation. Communities are unlikely to invest in measuring sustainability indicators unless monitoring provides immediate and clear benefits. However, in the context of goals, targets, and/or baselines, sustainability indicators can more effectively contribute to a process of development that matches local priorities and engages the interests of local people.

Local perceptions of sustainability indicators: issues of scale and implications for management

A key factor impacting upon sustainable development are the perceptions people hold of their local social, economic and ecological environment. These perceptions influence how communities fashion the local landscape and in turn help to condition the ways people adapt themselves to their local spatial realities. Implicit in these perceptions are indicators of sustainability that may or may not be integrated across the social, economic and ecological realms. Further, these local indicators may not accord with those adopted at the national or global scale. Accordingly, spatial scale presents a particular set of challenges in identifying appropriate indicators of sustainability. In the same way that aggregated changes at a local scale influence sustainability on a broad scale, national and global externalities profoundly affect perceptions relating to sustainable development at the finest of spatial scales.

This paper focuses on one aspect of the issue of scale in sustainable indicator selection: local perceptions of sustainability. In this paper we report on a survey of perceptions of sustainability conducted across thirty-two sub-catchments in three major catchments in south west Victoria. We sought to uncover what people within each sub-catchment perceived as socially, economically and ecologically sustainable. Responses were compared across sub-catchments to determine whether perceptions at the sub-catchment scale were shared across the region. The results indicate that perceptions of sustainability varied between sub-catchments, which means that perceptions relating to sustainability at the regional scale may mask local trends.

Sustainability indicators: is there consensus among stakeholders?

Measuring regional sustainability must include local approaches, as sustainability will be determined by what the community values and the relative importance of these values will depend on community expectations, which vary. One of the biggest challenges for introducing strategies for sustainability is that multiple stakeholders are involved and they have differing objectives. This paper reports on a study conducted in the south-west region of Victoria, Australia, which investigated the level of consensus among stakeholders involved in determining indicators for measuring the region's progress toward sustainability. Principal Component Analysis was used to determine if there was a difference between stakeholder groups when it came to selecting appropriate indicators. The organisations demonstrated a high degree of consensus about which indicators were important. These findings suggest that although organisations have different aims and strategic goals, their views on what should be measured to determine progress toward sustainability are indeed similar.

Urban growth in arid environments : developing water sustainability indicators for Abu Dhabi (UAE)

The United Arab Emirates (UAE) face a serious water problem. It has a very dry climate, high evaporation rate, combined with large water consumption from fast growing population, economic activities and uncontrolled uses of water for irrigation. Currently, UAE has one of the largest water footprints in the world. Groundwater is overexploited. Waste water is increasingly being treated to supply non-drinking water, but it still cover a small proportion of the demand. Desalination of sea water is the main source of potable water in UAE, but the high economic cost of desalination, its intensive energy demand and the adverse effects of its effluents on the marine life are a major concern. Other factors contributing to the problem are the focus of water management policies on keep supplying the growing demand for water, the increase of the per capita water consumption, and the free water charge for most of population. This research goal is to develop a water sustainability set of indicators for the challenging context of UAE. This paper presents the first stage of the research. Based on a review of the literature, the proposed framework involves 19 indicators, divided into four categories: water availability; water quality; water use efficiency; and policy and governance. Using an integrated cause-effect approach (DSR - Driving force, State, Response), the indicators were related in terms of their interdependencies, with a holistic view of the city water cycle. A preliminary test of the indicators to Abu Dhabi as a case study allowed an evaluation of the main 'Driving force' on the system, such as the scarcity of water due to natural constraints of the region, and increasing water consumption patterns of modern society; an assessment of the current 'state', which is under serious water stress. Also it indicated some potential 'responses', such as implementing policies for increasing efficient use.

Sustainability indicators for environmental management and decision making

The general objective of this research is to explore theories and methodologies of sustainability indicators, environmental management and decision making disciplines with the operational purpose of producing scientific, robust and relevant information for supporting system understanding and decision making in real case studies. Several tools have been applied in order to increase the understanding of socio-ecological systems as well as providing relevant information on the choice between alternatives. These tools have always been applied having in mind the complexity of the issues and the uncertainty tied to the partial knowledge of the systems under study. Two case studies with specific application to performances measurement (environmental performances in the case of the K8 approach and sustainable development performances in the case of the EU Sustainable Development Strategy) and a case study about the selection of sustainable development indicators amongst Municipalities in Scotland, are discussed in the first part of the work. In the second part of the work, the common denominator among subjects consists in the application of spatial indices and indicators to address operational problems in land use management within the territory of the Ravenna province (Italy). The main conclusion of the thesis is that a ‘perfect’ methodological approach which always produces the best results in assessing sustainability performances does not exist. Rather, there is a pool of correct approaches answering different evaluation questions, to be used when methodologies fit the purpose of the analysis. For this reason, methodological limits and conceptual assumptions as well as consistency and transparency of the assessment, become the key factors for assessing the quality of the analysis.
