The paper is based on a review of the established principles for evaluating the natural qualities of landscapes and developing procedures that can contribute to current methods, upgraded with ...indicators derived from the perception and attitudes of the public. They were implemented into an integrated model of natural landscape qualities. The method included modeling of the natural landscape qualities for the southern part of the Krka National Park in Croatia. The first evaluation model was based on a survey whose responses were processed and classified using the AHP method and GIS. The results showed that the respondents recognize the diversity of land cover and relief forms and the degree of their fragmentation as the highest natural landscape quality. The second step included overlapping the vulnerability model of natural landscape qualities and the model of perception of natural qualities. It was found that the implementation of perceived natural qualities in the evaluation process affects the model of vulnerability of landscape quality. It also indicates the possibility of implementing the perceived natural qualities of certain landscape types into the complete landscape evaluation process, which encompasses all values in the space, including human perception. Therefore, the whole procedure pointed out the importance of the implementation of perceived values into landscape evaluation, something which is also emphasized by the European Landscape Convention (ELC).
is a plant traditionally used for skin-related disorders that is becoming an increasingly popular ingredient in cosmetic products. In this work, a "green" ultrasound-assisted extraction method for
...phenolics was developed using skin-friendly cyclodextrins (CDs). Extraction conditions needed for the greatest yield of target compounds (total phenolics, phenolic acids, and flavonoids) were calculated. The composition of the extracts was determined using LC-MS and spectrophotometric methods. Among the tested CDs, 2-hydroxylpropyl-beta-CD (HP-β-CD) was the best suited for extraction of target phenolics and used to prepare two optimized extracts, OPT 1 (the extract with the highest phenolic acid content) and OPT 2 (the extract with the highest total phenol and flavonoid content). The extracts were prepared at 80 °C, using 0.089 g of plant material/g solvent (0.6 mmol of HP-β-CD), with or without addition of 1.95% (
) lactic acid. The main metabolite in both extracts was 3,5-
-dicaffeoylquinic acid. It was found that the addition of lactic acid greatly contributes to the extraction of arzanol, a well-known anti-inflammatory agent. IC
values of the anti-elastase (22.360 ± 0.125 μL extract/mL and 20.067 ± 0.975 for OPT-1 and OPT-2, respectively) and anti-collagenase (12.035 ± 1.029 μL extract/mL and 14.392 ± 0.705 μL extract/mL for OPT-1 and OPT-2, respectively) activities of the extracts surpassed those of the applied positive controls, namely ursolic and gallic acids. This activity deems the prepared extracts promising ingredients for natural cosmetics, appropriate for direct use in cosmetic products, removing the need for the evaporation of conventional solvents.
Increasing development pressure on the Croatian coastal zone has lead to environmental degradation due to a lack of appropriate strategies and policies in promoting well-planned and managed urban ...areas. Research has shown that six coastal cities have been facing problems connected with climate change (storm waters, floods, soil erosion and urban heath). Key elements of urban sustainability, in spatial context, are based on a balanced relationship between built and open urban spaces on one hand and connectivity between urban open spaces and between such spaces and surrounding landscapes at the regional scale (principles of urban green infrastructure). Detailed research based on comparative analysis shows that ecological problems have to do with unbalanced urban morphology in Dubrovnik (disappearance of green areas as absorptive surfaces and loss of connectivity). The findings offer a possible conceptual solution on applying the principles of green infrastructure, where the preservation and linkage of ecologically valuable green areas within urban fabric is crucial. These areas are planned as multifunctional spaces; they are important for biodiversity, urban morphology, and urban social life, as well as for mitigating the consequences of climate change.
The urban and landscape professions of the 21st century are developing diverse theoretical and practical models that they apply in solving the problems of the modern city. One of these models is ...landscape urbanism, which can be understood as a newer way of looking at the city and its infrastructure again, incorporating the relationship between the city and nature, and ecological and landscape principles into its fundamental core. In a theoretical but also a practical sense, it suggests new modalities that are considered to be able to contribute to the current problems of modern cities, especially those related to the ecology of the city. By reviewing the development stages, methodological framework and practical applications, this paper determines the potentials and limitations of the concept of landscape urbanism and suggests modalities of application in the modern city.
This paper investigated the need for the inquiry of landscape values and public participation within the decision-making process on spatial changes. They are taken into account as an important ...segment in the harmonization of conservation and development requirements in the planning of sustainable spatial development. The method for obtaining that information was established, and new approaches in landscape research were tested through the perception of its values as the first step to solving the conflicts between spatial conservation and development. Through the research of the experiences and theoretical knowledge on the nature protection issues within the spatial planning context, this paper indicated the need for determination of the effectiveness of the standardization approach to nature protection. Also, it emphasized the importance of testing a possible application of new approaches, which would be based on a mutually agreed approach to the protection and development of space. Modeling the landscape qualities of the space was presented as a basic tool within the presentation methodology and within the inclusion of different public segments in the spatial planning procedure. Its usefulness has been shown in the possibility of preparing the cartographic presentation of the harmonized model, which simultaneously includes the opinions of all relevant groups and can be easily implemented in the planning procedure using the GIS tools before decision-making. This paper pointed out that such an approach contributes to solving the practical problems in the protection of landscape qualities that represent public good and the link between nature and culture, and biophysical, perceptional, social, and developmental elements within the space.
This paper presents research on the conversion of the abandoned Kanfanar–Rovinj railway into a bicycle–pedestrian path, with the aim of including it in the existing network of bicycle–pedestrian ...paths in the Istria County in Croatia. This would enable better connection of the repurposed railway corridor with the surrounding natural and cultural values and better use of the spatial potential, which would create more favorable conditions for the revitalization of the wider rural environment. In order to identify the existing potential of the area, as well as the impact of the proposed intervention on critical areas, a method of multicriteria analysis was used. The result of the analysis was a model of the suitability of the space, i.e., five value categories that make the space more or less suitable for accommodating new pedestrian and bicycle paths. In order to emphasize the importance of individual spatial contents in the modeling process, the method of weighted linear combination was used. Finally, the nature of the project and its potential impact on the environment have conditioned the selection of the appropriate aspect of the model and of the space’s suitability, which is further used for locating the new pedestrian and bicycle paths.
This paper explores the application of sustainable nature-based solutions as an alternative to conventional grey infrastructure for managing waterways in the city of Zagreb, Croatia. The city has an ...extensive network of canalised urban streams, some of which are closed, flowing into the City’s sewage system and into the Sava River. However, some of these open watercourses are not fully utilised due to the inadequate management of blue infrastructure. Climate change adds pressure to conventional approaches, creating an urgent need for flexible solutions. This paper analyses different locations to assess the possibilities for safeguarding, revitalising, and developing blue and green infrastructure. Based on a thorough analysis, the synthesis of previous urban practice examples for the city area, and the research of the experiences and theoretical knowledge on the issue, this paper proposes sustainable solutions for Medveščak and Črnomerec streams in Zagreb, such as water storage and purification. The proposed solutions hold significant potential to address issues related to water supply, protection, and nature preservation in a more flexible and adaptable manner. This paper proposes solutions that provide a practical framework for the future implementation of nature-based solutions and development in other urban regions.

Research has been motivated by a wide range of concepts of the term urban green infrastructure. As the aim was to indicate a clear basis for the term, an investigation of its development was a ...necessity, not only in the European, but also in a broader context. Although green infrastructure is included in the 21st century policies of protection and development of EU landscapes, its foundations can be traced back to the models of ideal Renaissance towns and urbanist concepts mainly from the 19th and 20th century. In these historical periods used concepts meant urban landscapes as systems, a part of the environment, as seen in green corridors, green belts, green wedges, green networks and through the perception of urban green systems. As a modern concept the urban green infrastructure has been upgraded with developed roles, extending functions, scopes and scales from previous historical models. In that sense it maintains its social role of improving the quality of life in towns, while at the same time defining town texture with its urban morphological significance. At the same time it also develops ecological values and extends its scale to nonurban local, regional and international contexts.
Despite its benefits, spatial planning documents in the Republic of Croatia still lack measures and actions which would recognise the true benefit of green infrastructure in spatial development.
Dinara Mountain massif is recognized as an area of exceptional value, which led to its recent protection as a nature park, the second largest one in Croatia. The protected area includes the territory ...of two counties with four cities and nine municipalities, five of which are included with over 50% of the territory. The paper explains how landscape planning methods establish potential spatial conflicts and propose a compromise between landscape conservation and spatial development. The basic method was the identification and analysis of the landscape value models in 3 categories: natural, visual-experiential, and cultural-historical values. The creation of the models is preceded by a detailed analysis of all environmental components and the collection and creation of spatial data with the help of GIS tools. By overlapping the basic models, a cumulative model of the overall landscape values of the space is produced, which clearly shows which parts of the landscape have a higher value, regarding the protection requirements. The final value model is overlapped with the planned interventions and a clear overview of the vulnerability and possible conflict zones in the area is obtained. The paper describes the impact of individual interventions on the landscape qualities that need to be preserved and suggests guidelines for spatial plan corrections for the purpose of minimal impact on existing values, thus helping to prevent unwanted changes.
