RESUMEN

Many of the outcomes of environmental plans are difficult to measure. Therefore, little is known as to whether such plans achieve their goals, whether outcomes are reached and lessons learned to influence future plans. Our study aims to address this gap by systematically evaluating the implementation of Local Environmental Action Plans (LEAPs) of 29 counties in Romania and the factors affecting it. We draw on both quantitative (official statistical data) and qualitative (planners' assessments) evaluation methods and two conceptions of plan implementation success (conformance and performance based) to assess LEAP implementation. Our findings indicate mixed levels of conformance and performance. While the implementation of LEAPs conforms with the plans from the perspective of progress of overall policy implementation, this does not conform with the plans in terms of positive changes on the ground. LEAPs perform well in mitigating local environmental problems and coordinating with other planning initiatives but badly in terms of their usefulness in the decision-making process, having little influence on lower-level plans. Furthermore, the quality of LEAPs may not be important in relation to their implementation, while investments in the capacity of planning agencies, as well as local political support and participatory approaches, may improve the implementation of LEAPs in the future. The results of our study may assist the devising bodies in enhancing the implementation of future versions of LEAPs by revealing the main opportunities and constraints influencing implementation.

RESUMEN

Environmental action plans are important instruments intended to provide sustainable solutions for the most pressing environmental issues. As they should be updated regularly, efforts to evaluate their quality are essential for enabling incremental improvements in upcoming versions. The aim of our study was to systematically evaluate the quality of Romania's Local Environmental Action Plans (LEAPs) by following a theoretical framework that includes principles from both rational and communicative approaches to assessing plan quality. We selected 32 LEAPs and applied an evaluation protocol that enabled a comprehensive assessment of the plans. Our results showed an overall moderate quality of the LEAPs. Although most plans identify many environmental problems in need of solutions, in reality additional urgent environmental problems often exist. Furthermore, LEAPs perform only moderately in identifying tools for implementation provisions and ensuring the participation of the public in the planning process, and they are even weaker in establishing goals and achieving coordination across different governmental levels. Overall the assessment reveals that plans are rarely able to craft an appealing policy message. Our findings could be used as guidance for LEAP coordinating agencies to improve the plans in the upcoming updating processes, as they identify plan weaknesses and suggest ways to achieve high quality environmental plans. Furthermore, our novel plan assessment method based on rational comprehensive and communicative approaches to plan quality evaluation can be adapted easily to other studies.

RESUMEN

Nutrition is considered as one of the main drivers of global environmental change. Dietary patterns in particular, embedded in the international trade of foods and other biomass based commodities, determine the dimension of beneficial or harmful environmental impacts of the agri-food sector - both domestically and abroad. In this study we analysed different dietary scenarios from a virtual land flow perspective, based on representative consumption data for Germany in the years 2006 and 1985-89. Further we identified the consumer groups that would have to adapt most to balance Germany's virtual land import and analysed the impact reduced food wastage. For the study, official data sets concerning production, trade and consumption were used. We derived land use data from environmentally extended input-output data sets and FAO statistics. The conversion of agricultural raw products to consumed commodities is based on official processing and composition data. Subgroup-specific intake data from the last representative National Nutrition Survey in Germany were used. We analysed 42 commodities, aggregated into 23 product groups, seven land use types and six nutrition scenarios. The results show that in the baseline scenario the average nutrition in the year 2006 leads to a virtual land import of 707m(2)p(-1)a(-1), which represents 30% of the total nutrition-induced land demand of 2365m(2)p(-1)a(-1). On the other hand, the German agri-food sector exports virtual land, in the form of commodities, equivalent to 262m(2)p(-1)a(-1). In this paper we calculate that the resulting net import of virtual land could be balanced by way of a shift to an officially recommended diet and a reduction in the consumption of stimulants (cocoa, coffee, green/black tea, wine). A shift to an ovo-lacto-vegetarian or vegan diet would even lead to a positive virtual land balance (even with maintained consumption of stimulants). Moreover, we demonstrate that a shift in the average diet profile could lead to maintained or even expanded export competitiveness and simultaneously enable environmental benefits. Since such a diet shift complies with official dietary recommendations, it follows that public health benefits may well result. We show further that a reduction of avoidable food losses/wastage would not be sufficient to level out the virtual land balance of the average nutrition in Germany. Regarding the dietary developments in the last 20years, we argue that a dietary shift resulting in a zero land balance is within reach. The population groups that would have to be addressed most are younger and middle-aged men. Nevertheless, women's land saving potentials should not be ignored neither. Due to the fact that a western-style diet prevails in Germany, we argue that our basic findings are applicable to other industrialised and densely populated countries.

RESUMEN

Soil sealing has negative impacts on ecosystem services since urban green and soil get lost. Although there is political commitment to stop further sealing, no reversal of this trend can be observed in Europe. This paper raises the questions (1) which strategies can be regarded as being efficient toward ecologically sustainable management of urban soil sealing and (2) who has competences and should take responsibility to steer soil sealing? The analyses are conducted in Germany. The assessment of strategies is carried out using indicators as part of a content analysis. Legal-planning, informal-planning, economic-fiscal, co-operative, and informational strategies are analyzed. Results show that there is a sufficient basis of strategies to secure urban ecosystem services by protecting urban green and reducing urban gray where microclimate regulation is a main target. However, soil sealing management lacks a spatial strategically overview as well as the consideration of services provided by fertile soils.

RESUMEN

Determining the performance of ecosystem services at the city or regional level cannot accurately take into account the fine differences between green or gray structures. The supply of regulating ecosystem services in, for instance, parks can differ as parks vary in their land cover composition. A comprehensive ecosystem service assessment approach also needs to reflect land use to consider the demands placed on ecosystem services, which are mostly neglected by current research yet important for urban planning. For instance, if a sealed surface is no longer used, it could be unsealed to improve ecosystem service supply. Because of these scientific shortcomings, this article argues for a conceptual framework for the non-monetary assessment of urban ecosystem services at the site scale. This paper introduces a standardized method for selecting representative sites and evaluating their supply of and demand on ecosystem services. The conceptual design is supplemented by examples of Salzburg, Austria.

RESUMEN

Although a number of comprehensive reviews have examined global ecosystem services (ES), few have focused on studies that assess urban ecosystem services (UES). Given that more than half of the world's population lives in cities, understanding the dualism of the provision of and need for UES is of critical importance. Which UES are the focus of research, and what types of urban land use are examined? Are models or decision support systems used to assess the provision of UES? Are trade-offs considered? Do studies of UES engage stakeholders? To address these questions, we analyzed 217 papers derived from an ISI Web of Knowledge search using a set of standardized criteria. The results indicate that most UES studies have been undertaken in Europe, North America, and China, at city scale. Assessment methods involve bio-physical models, Geographical Information Systems, and valuation, but few study findings have been implemented as land use policy.
