The political objective calling for environmentally sustainable development has provided the canvas for lively dialogue amongst scientists and analysts. Be that as it may, what have been found wanting are operational conditions for the achievement of environmental sustainability within specific anthropogenic systems, with cities being cited as a prime example of such systems. Indeed, from a historical perspective, cities have always been based on the concentration of humans and man‐made elements, resulting in respective confinement of natural assets. As cities possess particular properties for their environmental basis, the general conditions governing sustainability require suitable modifications when applied to cities. In this context, the present paper examines the conditions for environmentally sustainable development in urban systems. The specific natural and socioeconomic characteristics of urban systems are systematically taken into account for defining environmentally sustainable development in cities. The paper proposes an operational framework for evaluating urban systems for their environmental performance. Urban systems, presenting specific characteristics necessary for creating welfare with high density, ask for particular conditions for their environmentally sustainable development. These conditions differ substantially from those defining sustainability in broader geographical systems. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.

For many decades, the Region of Western Macedonia has been Greece’s energy hub, contributing significantly to electricity supply and national growth with the exploitation of lignite deposits for power generation. Lignite, though, has been banned from EU energy source policies towards achieving CO₂ emissions reduction, with profound implications on the economy of the region. Despite the importance of this energy transition, a combinatorial analysis for the area in the coal phase-out regime is missing. Therefore, a combined analysis is performed here, and more specifically, a strengths, weaknesses, opportunities, and threats (SWOT) analysis in all the affected sectors, in combination with the examination of the degree of satisfaction with the EU’s energy priorities. The results of the study show that the Region of Western Macedonia has profound strengths and offers many new opportunities during its transition to a new production model. On the other hand, it has high unemployment rates and low rates of competitiveness and innovation. The main threat is the Region’s desertification due to the inability to find sufficient jobs. Considering the Energy Union’s priorities, the Region of Western Macedonia satisfactorily follows the priorities of Europe in its transition to the new production model, with plenty of room for improvement. The analysis performed allows for a just transition strategic planning to minimize social, economic and energy challenges while maximizing sustainable power generation and has implications for all relevant stakeholders, contributing to the implementation of Energy Union governance and climate actions.

The current European policy on water resources use in cities is undergoing radical reform in an attempt to confront the water quality problems and the dramatically intensified water scarcity. Among the most elaborate documents concerning current water policy is the Water Framework Directive (WFD), which spells out the targets of water policy at the European level. The confrontation of water scarcity, deterioration in quality, and the reduction in costs of the water supply industry emerge as decisive principles of the new European policy on water use in cities. These targets are currently assimilated in the agendas of national water policies in almost all European countries. To achieve these objectives several policy instruments have been applied in Europe. The more prevailing instruments are: demand management, privatization of water companies and efficient/full cost pricing of water use. The present article aims at systematically evaluating the effectiveness and efficiency of the current water policy for urban systems, by examining the coherence of its instruments as well as their appropriateness for achieving the policy's targets. To start with, the paper presents an elementary economic analysis of the current water policy. The effects of the most common policy instruments are systematically traced in the framework of economic analysis. Next, three indicative case cities are presented and examined. As it turns out, however, the results of the implementation of the main instruments are contradictory. This drastically reduces the effectiveness of the water policy. We indicate that these contradictory effects are inherent in the water policy and originate in the lack of appropriate social processes and institutions for the management of natural resources.

The concept of Ecologically Sustainable Economic Development (ESED) has led to relentlessly heated debate. Yet, it still remains without a clear operational framework. At the micro level where a multitude of projects and programmes are designed, the absence of operational principles has serious repercussions. In order to tackle this ineffectiveness, ESED may be viewed as a pattern of economic process and evolution that takes into account the constraints imposed by the natural environment. In effect, the economic process should ensure the preservation of the human race by maintaining the biological basis responsible for the healthy evolution of the race. In addition, economic development should not lead to Pareto suboptimal positions by precluding production potentials. Based on these principles, the present paper outlines an operational framework for ESED at the micro level of projects and programmes. Copyright © 2006 Inderscience Enterprises Ltd
