Do post-socialist urban areas maintain their sustainable compact form? Romanian urban areas as case study

The compact city is regarded as an important concept in promoting sustainable development, especially within the European Union. The socialist urban planning system maintained a high compactness of the urban areas through almost exclusive predominance of the public sector in housing provision, and ideological nature of the planning strategies. After the 1990's, the administrative decentralization allowed local authorities to adopt particular urban development strategies. However, development was directly influenced by the importance of the urban administrative centre. The aim of the paper is to determine if post-socialist urban areas maintained their compact urban form or they encountered different evolution trajectories. We determined the type of changes by calculating urban form indicators at two time moments: 1990 and 2006. Furthermore, the two-way repeated-measurement ANOVA was used to identify significant changes, and to assess the effect of the development level of the urban area on the variance of form indicators. The results show that Romanian post-socialist urban areas either shifted from the compact form, "inherited" after the collapse of socialism, to more dispersed patterns, either expanded in a compact manner. Moreover, as development level got higher, urban areas were more likely to be affected by suburbanization and periurbanization. In order to respond to these challenges, new instruments such as setting of metropolitan areas or spatial framework plans could be used. Furthermore, planning should be adapted to local circumstances and to the different development trajectories of big and mid-sized urban areas

Correlation of Dissolved Organic Matter Fluorescence and Several Metals Concentration in a Freshwater System

AbstractDissolved organic matter (DOM) strongly influences several ecosystem processes, including the reduction of solar radiation, control of nutrient availability, modification of contaminant toxicity, and energy cycling. Using fluorescence spectroscopy, one of the most important DOM features, metal binding affinity, has been characterized, due to its direct effect on aquatic ecosystems. This paper presents the analysis of the relationship between type and concentration of metal ions and DOM fluorescence for water sampled from Arges River. The results suggest that certain competitive complexation processes occur among metal ions and that iron and chromium ions have the most significant impact on DOM fluorescence

Spatial analysis of locational conflicts: case study: locational conflicts generated by the expansion of built up surfaces in the northern area of Bucharest, Romania

The aim of this paper is to identify and analyze land use conflicts existing in the northern area of Bucharest and to spatially model their impact on the expandint residential areas. The main objectives are: 1) to analyze the dynamics of built up surfaces between 1975-2010; 2) to analyze the spatial and temporal dynamic of locational conflicts and 3) to spatially model the impact of locational conflicts on residential areas.Peer Reviewe

Scaling up from protected areas in England: The value of establishing large conservation areas

Protected areas (PAs) are vital for conserving biodiversity, but many PA networks consist of fragmented habitat patches that poorly represent species and ecosystems. One possible solution is to create conservation landscapes that surround and link these PAs. This often involves working with a range of landowners and agencies to develop large-scale conservation initiatives (LSCIs). These initiatives are being championed by both government and civil society, but we lack data on whether such landscape-level approaches overcome the limitations of more traditional PA networks. Here we expand on a previous gap analysis of England to explore to what extent LSCIs improve the representation of different ecoregions, land-cover types and elevation zones compared to the current PA system. Our results show the traditional PA system covers 6.37% of England, an addition of only 0.07% since 2001, and that it is an ecologically unrepresentative network that mostly protects agriculturally unproductive land. Including LSCIs in the analysis increases the land for conservation more than tenfold and reduces these representation biases. However, only 24% of land within LSCIs is currently under conservation management, mostly funded through agri-environment schemes, and limited monitoring data mean that their contribution to conservation objectives is unclear. There is also a considerable spatial overlap between LSCIs, which are managed by different organisations with different conservation objectives. Our analysis is the first to show how Other Effective Area-Based Conservation Measures (OECMs) can increase the representativeness of conservation area networks, and highlights opportunities for increased collaboration between conservation organisations and engagement with landowners

The role of urban green spaces in care facilities for elderly people across European cities

Urban green spaces (UGS) are increasingly acknowledged for their importance for the well-being of urban populations. However, studies are lacking the consideration of the demand and use of UGS by different population groups and connecting UGS with social infrastructure. In an era of worldwide urbanization and ageing, this European study sheds light on the role of UGS for care facilities for elderly. 126 care facilities from 17 cities in Austria, Germany, Norway, Poland, Romania and Slovenia took part in an online survey. Administrations of care facilities gave insights on the (1) importance of gardens related to care facilities for the quality of life for the seniors, (2) importance of UGS outside of care facilities for the quality of life for the seniors and (3) the consideration of natural and age-friendly designs and management of ecosystem disservices of UGS. The results emphasize not only the importance of UGS for the quality of life of seniors residing in care facilities, but also for the staff and visitors. UGS contribute to physical activities, recreation, and social interactions. The study found that in particular facilities with an own garden are highly aware of the benefits UGS provide. The study holds important lessons for urban green space planning, management and design not only to focus on the quantitative supply of UGS, but also to consider age-sensitive amenities in and access to UGS of high quality for seniors. social infrastructure, urban green space design, urban green space access, healthy ageing, urban green space management, quality of lifeacceptedVersio

Conflicting interests between local governments and the European target of no net land take

To halt land take in Europe, the European Union set a “no net land take by 2050″ target in 2011. However, land take continues to occur in European countries, with recent studies suggesting that local decision-making is playing a major role in these land-use conversions. In this study, we investigated how urban growth boundaries (UGBs) are used by local governments to manage urban growth in Romania. A mixed-method approach was adopted, combining analysis of UGB changes over the past decade in all Romanian cities (N = 319) with a survey among representatives of local governments involved in land-use decision-making (N = 91 cities). The results showed that many cities have expanded their UGBs, despite population loss and sufficient undeveloped land within UGBs, showing that local government decisions conflict with policy targets at the European level. This is even the case when there is no physical need for land-take limits to be exceeded. We show that population dynamics and the extent of nature conservation areas significantly contribute to UGB changes, though these explain just a small fraction of all UGB changes. Furthermore, we identified a wide range of motivations among decision-makers regarding changing UGBs, including not only the fiscal system but also cities’ competitiveness and decisions about the long-term vision for development. We argue that policy innovations in urban containment should (i) aim to balance the interests of governments at different administrative levels, (ii) account for the particularities of each state member's planning system, and (iii) allow for integrated and strategic city planning
