Recently the planning of green infrastructure (GI) has become a general practice around metropolis (Paris, München, Budapest, etc). A complex methodology is required that goes beyond the scope of traditional green surface systems. However, there are various policy implications in the EU, the smaller towns are lagging to apply them. The paper presents a potential evaluation method through the case study of Keszthely, HU. As Keszthely at Balaton Riviera, is a popular touristic target of CEE, the environmental planning is an essential part of sustainable development. After a literature analyses of assessment methods of GI and ecosystem services, the aspects of GI have been valued on grade scales, based on field surveys and indicators. The current status of the GI was surveyed which is a base for further development and monitoring activities. The paper introduces the methodology, which contributes to preservation of ecosystems.

Environmental Impact Assessment (EIA) has been formally applied in Germany since 1990, and has over time developed a methodological and technical routine in environmental planning practice. It can now be considered an established instrument; nonetheless, substantial challenges to the further development of the EIA, and to even stronger implementation of environmental requirements in planning and decision-making practice in Germany, still exist. This paper reports briefly on the application and the main achievements of the EIA in Germany, and, in the second section, primarily provides a perspective for addressing remaining and new challenges involving this instrument. The paper also includes specific proposals for the further optimization of the EIA at the EU level, as well as for Germany. The current status and future challenges facing the EIA, which are described herein, range from screening and scoping through public participation and monitoring to the area of application.

This study highlights the importance of including detailed (local-scale) biodiversity and ecosystem services data for land-use management and promotion of protected areas using the National Park and UNESCO Global Geopark of Chelmos-Vouraikos (Greece) as a case study. Along with the conducted field surveys and literature review for the National Park’s flora documentation, ecosystem type mapping and assessment of ecosystem services have been performed, following National and European Union (EU) guidelines for the Mapping and Assessment of Ecosystems and their Services (MAES) implementation across EU Member States. Main results include floristic diversity indicators, ecosystem type mapping and assessment, and ecosystem services identification and assessment of their actual and potential supply. By this, a scientifically informed baseline dataset was developed to support management and policy needs towards a holistic National Park management and a sustainable spatial planning for protected areas. Additionally, local scale ecosystem type and ecosystem services data have been produced as input for the MAES implementation in Greece and the EU.

Abstract In Vietnam, pond culture of marine finfish including mullet, milkfish and seabass has been developed since the 1960s (Dao, 1996) and significant expansion took place in the early 1990s with the appearance of a live fish market. Groupers (Epinephelus akaara, E. bleekeri, E. coioides, E. fuscoguttatus, E. malabaricus, E. merra and E. sexfasciatus) are currently among the major cultured species. There are approximately 500 ha of coastal pond culture of marine finfish in Vietnam producing more than 1,000 t of products, mainly groupers with a farm gate value of more than VND100 billion (more than US$7 million) in 2003. Khanh Hoa, a province in the south of central Vietnam with an area of 5,258 km2 and a population of approximately 1 million, is one of major localities producing groupers in ponds with a total estimated production of 100 t in 2003. This case study reviews the current status of pond culture of groupers, and identifies major technical, economic and social constraints to further development in Khanh Hoa province as well as elsewhere.

AbstractThe arrival of new customers along the new Iron Silk Road also brings new transport opportunities. The liberalization of railway transport has created many wagons over the railway market throughout the EU, especially in the field of freight transport. Choosing the preferable carrier that can fit the needs of customers is challenging. Each rail freight operator currently shapes its profile by focusing on a specific group of commodities as a matter of priority. By specializing, they gain a dominant market position in their sector that helps them to maintain and expand their clientele. The article aims at bringing a decisive system with clear rules and standards for choosing the right business partner in the freight railway market. The article is designed as a case study that starts with an analysis of four different freight carriers. Other parts of the article are about the evaluation of their ability to meet the needs of a customer.

Computer-aided conceptual design of mechatronic products is becoming more and more important since it offers much convenience in design scheme retrieval and enhances the utilization of existing designs. One of the key technologies for computer-aided conceptual design is an efficient search algorithm for retrieving existing designs. As such, it’s necessary to find a feasible way to select the most suitable design out of a number of candidates for further development. By applying behavioral modeling method for representation of conceptual design, this paper proposes a node matching algorithm for searching behavioral model, together with a model similarity evaluation method. Based on these methods, a framework for computer-aided conceptual design is subsequently proposed. Finally, a case study is presented to illustrate the applicability of the proposed methodologies.

Abstract Cage culture of lobsters started in Vietnam in 1992 in Khanh Hoa province. Since 2000, there has been significant expansion in lobster culture in southern central Vietnam from Da Nang City to Binh Thuan province. Ornate or spiny rock lobster (Panulirus ornatus) is the most important cultured species but P. hormarus, P. longipes and P. stimpsoni are also cultured. There are approximately 33,000 grow-out cages of which 17,000 are located in the coastal waters of Khanh Hoa province. These marine cages produce approximately 1,500 t of lobsters with a farm gate value of more than US$40 million in 2003. This case study reviews the current status of cage culture of lobsters, and identifies major technical and socio-economic constraints to further development.

<abstract> <p>The tunnel collapse is one of the most frequent and harmful geological hazards during the construction of highway rock tunnels. As for reducing the occurrence probability of tunnel collapse, a new dynamic risk assessment methodology for the tunnel collapse was established, which combines the Cloud model (CM), the Membership function, and the Bayesian network (BN). During the preparation phase, tunnel collapse risk factors are identified and an index system is constructed. Then, the proposed novel assessment method is used to evaluate the probability of tunnel collapse risk for on-site construction. The probability of tunnel collapse risk in the dynamic process of construction can provide real-time guidance for tunnel construction. Moreover, a typical case study of the Yutangxi tunnel is performed, which belongs to the Pu-Yan Highway Project (Fujian, China). The results show that the dynamic evaluation model is well validated and applied. The risk value of tunnel collapse in a construction cycle is predicted successfully, and on-site construction is guided to reduce the occurrence of tunnel collapse. Besides, it also proves the feasibility of the dynamic evaluation method and its application potential.</p> </abstract>

As we all know, the degree of farmland immersion is affected by many factors such as soil moisture content, natural pore ratio, saturation, soil lithology and so on. However, the conventional submergence assessment method only uses the relative relationship between the depth of phreatic water and the rising height of capillary water to judge the degree of submergence, which is obviously unreasonable. Therefore, in this paper, a method of farmland immersion evaluation based on trigonometric whiteness weight function grey clustering is proposed. The physical properties of soil, surface soil lithology of vadose zone and groundwater level elevation are included in the evaluation index system, and the degree of submergence is classified, and then the weight function is constructed to determine the degree of submergence hazard of each observation point in the immersion area. Case study shows that the method is reasonable and feasible for farmland immersion evaluation.

Standardized delimiting of local climate zones (LCZ) will be better applicable to the urban adaptation to climate change when the ecohydrological properties of LCZ units are known. Therefore, the properties of LCZ units based on the methodology of ecohydrological zoning of the urban landscape, which was created in GIS as a basis for planning blue-green infrastructure of cities in the Czech Republic, are presented in the paper. The goal of this study is to compare approaches and results of our own ecohydrological zonation and standardized LCZ delimiting in the city of Pilsen. Both methodological approaches differ in input data, resolution details and parameters used. The results showed that the areas of the individual LCZ classes show different levels of ecohydrological qualities. Internal heterogeneity of LCZ classes demonstrated by variance of ecohydrological parameters’ values can be partly explained by different techniques and data sources for delimitation of both zonations, but by different sets of delimitation criteria. The discussion is held on the importance of terrain slope for supplementing the LCZ classification. A case study can be a stimulus for further development of holistic urban zoning methodologies that would take into account both climatological and ecohydrological conditions.
