This study aims to conduct a survey of visitor reviews of the Plitvice Lakes National Park in Croatia to detect strengths and weaknesses of the park. In total, 15,673 reviews written in the period between 2007 and 2021 were scraped from the social media platform TripAdvisor. The research applies a comprehensive combination of multidimensional scaling, sentiment analysis, and natural language processing approaches to a sample area of international naturalistic interest. Analyzing the opinions of visitors, the authors identify: the main topics of interest related to the management of the park; and the strengths and weaknesses on the basis of definitely positive and decidedly negative reviews, respectively. The tested methodology is easily applicable for the analysis of different naturalistic contexts and protected areas, even in different countries, thanks to the use of translated reviews. The results obtained show that visitors to protected natural areas are not only interested in naturalistic and landscape aspects but also in issues such as accessibility and management of routes and visits.

Cultural ecosystem services (CESs) are non-material benefits generated by natural and human ecosystems that substantially contribute to human wellbeing. Estimating the monetary value of CESs is challenging because there is no real market for these services and therefore there is no actual market price. This study seeks to define an economic evaluation method for these services, with special reference to a recreational CES that has so far received little discussion: hunting. We conducted an online survey in the province of Siena (Tuscany, Italy). The Consumer Surplus estimate of hunters was made using the travel-cost method with a detailed analysis of the annual expenditure on hunting activities, and a negative binomial statistical regression. The results reflect the nature of hunting activity and show the dynamics that have occurred over recent decades. In fact, whereas hunting used to be strongly connected to the rural world as it was an income supplement for local communities, nowadays it has turned into an elitist and almost exclusively recreational activity. In any case, knowing the economic value of ecosystem services constitutes an essential background for planning effective land management and development policies in the short and long term.

The purpose of this study was to examine two biomass district heating plants operating in Tuscany, with a specific focus on the ex-post evaluation of their economic and financial feasibility and of their environmental benefits. The former biomass district heating plant supplies only public users (Comunità Montana della Lunigiana, CML: administrative body that coordinates the municipalities located in mountain areas), the latter supplies both public and private users (Municipality of San Romano in Garfagnana). Ex-post investment analysis was performed to check both the consistency of results with the forecasts made in the stage of the project design and on the factors, which may have reduced or jeopardized the estimated economic performance of the investment (ex-ante assessment). The results of the study point out appreciable results only in the case of biomass district heating plants involving private users and fuelled by biomasses sourced from third parties. In this case, the factors that most influence ex-post results include the conditions of the woody biomass local market (market prices), the policies of energy selling prices to private users and the temporal dynamics of private users’ connection. To ensure the consistency of ex-post economic outcome with the expected results it is thus important to: (i) have good knowledge of the woody local market; (ii) define energy selling prices that should be cheap for private users but consistent with energy production costs and (iii) constrain private users beforehand to prevent errors in the plant design and in the preliminary estimate of return on investment. Moreover, the results obtained during the monitoring activities could help in providing information on the effectiveness of the supporting measures adopted and also to orient future choices of policy makers and particularly designers, to identify the most efficient configuration of district heating organization for improving energy and environmental performances of communities, and to develop a chain model for the optimization of energy use in the municipality.

Urban parks are key components of metropolitan green infrastructure, contributing to residents’ well-being. However, perceptions of disorder and safety may substantially shape how these spaces are experienced, particularly during evening hours. This study investigates the structural relationships between perceived disorder, fear of crime, avoidance behaviors, perceived safety, and service satisfaction. The primary objective is to disentangle the pathways linking disorder perceptions to behavioral and perceptual outcomes using a Structural Equation Modeling (SEM) framework. A structured survey was administered to users of a large metropolitan urban park (N = 742). Latent constructs representing Perceived Disorder, Fear of Crime, Avoidance Behaviors, and Service Satisfaction were specified, controlling for Age and Gender. The SEM was estimated using robust methods for ordinal indicators. The measurement model demonstrated good reliability and validity. Results indicate that Perceived Disorder acts as a strong precursor to Fear of Crime. Fear of Crime emerged as a pivotal mediator, significantly increasing Avoidance Behaviors and strongly reducing Perceived Safety at night. Furthermore, significant demographic effects were observed: female users reported significantly higher levels of fear, while age showed a direct positive association with perceived safety. While disorder strongly impacted the emotional and behavioral dimensions (fear and avoidance), its direct link to Service Satisfaction was less prominent compared to safety perceptions. The findings suggest that the impact of disorder on the park experience is largely channeled through psychological mechanisms of fear. Integrated policies addressing social disorder and fear reduction are likely to be more effective than purely physical interventions to enhance safety perceptions and park usage.
