Irrigated agriculture has considerable impacts on the environment. To minimize negative effects and maximize positive effects, it is necessary to provide comprehensive analyses beyond the strictly technical domain. In this study, we apply a methodology for determining priorities in implementing irrigation plans using multi-criteria analysis methods on a specific case study area in the sub-catchment area of the Orljava River in Požega–Slavonia County, Croatia. Five potential irrigation areas (Orljava–Londža, Pleternica, Ovčare, Treštanovci, and Venje–Hrnjevac) were analyzed according to five selected criteria: environmental protection, water-related (four sub-criteria), social, economic, and time criteria with different criteria importance (weight). The aim of this study was to confirm the adequacy of using six multi-criteria analysis (MCA) methods (mostly used: PROMETHEE, AHP, ELECTRE TRI, and the less used: DEXi, PRIME, and PCA) in determining priorities for fulfilling irrigation plans, present models for preparation of the input data, apply certain methods, and compare the results on the selected case study area. The methods’ adequacy was confirmed during the research. Five of the six MCA methods identified the Ovčare area as the most appropriate for irrigation development (i.e., it has priority in implementing the irrigation plan). According to one (AHP) of the six methods, Orljava–Londža has more advantages over other areas. All MCA methods, except PCA, chose Venje–Hrnjevac as the least advisable (last to be implemented) alternative. Conclusions from this research confirm findings from recently published research regarding the application of MCA on water management problems.

Solid Waste Landfills

Ultimate disposal of wastewater sludges is one of the most concerning steps of sludge management. As an alternative disposal, reuse of sludge as a soil conditioner or fertilizer has had some success. Another alternative is the addition of sludge to the solid waste landfills. Many researchers have studied the effects of sludge addition to the solid waste stabilization in landfills. However, part of the researchers found positive effects, while others found either negative effects or no effects at all. This study investigates the remaining stabilization potential of the solid waste retrieved from an operating landfill by sludge addition. Determination of the remaining stabilization potential of landfilled solid waste is an important issue in solid waste management. In this study, the further stabilization of landfilled solid waste is achieved by the addition of anaerobically digested sludge to the solid waste with different sludge to waste ratios. Four 10-litre laboratory-scale batch digesters operated under constant temperature of 34°C are used in the experiments. One of the digesters was the control unit operated without any sludge addition. The other three digesters had different sludge to waste ratios; 1:9, 1:6, 1:4 (on wet basis) respectively, in order to find the optimum ratio for the solid waste stabilization. The comparison of gas production and quality and other indicator parameters provided an opportunity to determine the remaining stabilization potential and its significance. The results are translated in terms of conventional landfill practices, as well as emerging technologies for innovative sludge management.

The Relationship

The long-term and uncontrollable stress of KPSS (Personnel Selection Examination) candidates disrupts their psychology, weakens thinking and decision-making, and thus decreases academic achievement. The aim of this study is; It is the determination of the relationship between the level of hope and perceived stress of teacher candidates prepared for KPSS.A total of 382 teacher candidates participated in a special KPSS preparatory course in Kayseri. Candidate teachers who graduated from different departments and universities are between the ages of 21-25 in 41.6%. When we look at socio-demographic characteristics; 68.4% male; 59.9% single and 51.5% were at medium income level. Perceived Stress Scale (PSS-10) and Adult Hope Scale (AHS) were administered to the participants. The mean AHS score of the teacher candidates was 27.73±1.92. This shows the high level of hope of the participants. Perceived Stress level was found to be medium at 53.6%. As a result of the analysis, a significant a negative correlation was found between level of hope and perceived stress (p <0.01). According to regression analysis, level of hope in teacher candidates showed a statistically significant positive effect on perceived stress (p <0.01).As a result, negative relationships were found between hope and perceived stress. It is thought that highly hopeful people perceive stress lower and life satisfaction increases. Therefore, in order to increase the level of hope and to reduce the negative effects of stress, educators should support KPSS candidates. Programs related to the high level of hope to be implemented in schools may have positive effects on individuals' low stress and examinations.

Ecotourism can be defined as responsible travel to natural areas that conserves the environment and cultural heritage and improves the well-being of local people. Sustainable planning and management of ecotourism development are important and necessary for increasing positive and decreasing negative effects on the complex environment. This paper analyses the suitability of selected protected natural areas in the Serbian Danube region for the purposes of ecotourism development. The multi-criteria analysis includes several natural and socio-economic factors and criteria which influence ecotourism development. The integration of Geographic Information System (GIS) and Analytic Hierarchy Process (AHP) greatly facilitates the decision-making process in the ecotourism destination planning. A suitability map of the analysed protected natural areas for ecotourism development as one of the sustainable tourism types is highlighted as a result of this paper. Such analysis assists in the objective promotion of ecotourism destinations and thus contributes to the improvement of Serbian tourism development.

AbstractNegative effects of tourism development in a destination are usually the consequence of the high concentration of tourists, accommodation facilities and the activities that are practiced in a relatively restricted area. One of the most important measures to protect the areas is to calculate the maximum number of tourists that can simultaneously reside in a region, i.e. the determination of the carrying capacity. This paper outlines a method for determining carrying capacity based on zoning of environmental resources and zoning within a region. The paper argues for a return to the idea of identifying maximum appropriate number of users. The main hypothesis of the paper is based on the statement that the development of tourism in Fruška Gora (Mountain) National Park in Northern Serbia must be in accordance with the basic principles of sustainability, including the determination of carrying capacity. The main research goal was to show the opinion of local residents about the uncontrolled development of tourism, and to determine the carrying capacity in four sports and recreational zones of the mountain. The carrying capacity of the area is calculated by Lavery and Stanev formulas.

Ongoing Monitoring

The concept of sustainable tourism development presupposes constant endeavour, ongoing monitoring, and improvement of all stakeholders involved in order to minimize the negative and maximize the positive effects of tourism. The authors of the paper examine a case study of the area of Goriška Brda (municipality of Brda), located in the western part of Slovenia along the border with Italy, where the predominant (traditional) economic activity is agriculture, and more recently tourism as well. The question is whether the development of tourism in Brda has been sustainable, and how it has affected the life of the local population. What are the perceptions of the local residents of the various effects of tourism in their municipality? Analysis of the state of tourism and a survey research on a representative sample of the local population highlighted predominantly positive influences and consequently positive perceptions. Many inhabitants of the Brda municipality are directly or indirectly dependent on tourism, so they are willing to overlook or minimize the existing negative effects.
