The sustainable management of forest resources is greatly influenced by forest operations (FO). Interactions between humans and nature describe how people engage with and are impacted by the natural world. As we enter the Anthropocene epoch, we are being compelled to reevaluate our past and present methods of managing and planning our forest operations in order to find new ones that are more adaptable and successful at addressing the growing unpredictability resulting from accelerating global change. We briefly discuss the goals and constraints of the prior and current management and planning principles for forest operations in this study, focusing on how these principles have evolved on a worldwide scale. We then propose a promising idea, such as managing forest operations as complex adaptive systems and approaches based on resilience and sustainable use of forest resources, in order to achieve the necessary economic, social, and ecological goals. An in-depth understanding of the ecological, economic, and social factors that influence forest resilience is necessary for planning and managing forest operations efficiently. The proposed strategy combines the effectiveness of forest operations with a functional, complex network approach in order to manage forests for the Anthropocene.

The sustainable management of forest ecosystems is directly linked to the management of forest fires. The increasing occurrence of wildfires has prompted the need for the establishment of infrastructure aimed at addressing them. The placement of anti-fire water reservoirs can address the lack of water intake points. This study introduces a decision support system (DSS) tailored for the optimal allocation of anti-fire water reservoirs in Mediterranean forest ecosystems, ensuring a reliable water supply for firefighting operations. The methodology integrates the analytical hierarchy process (AHP) and the technique of order of preference by similarity to ideal solutions (TOPSIS) methods, facilitating precise location determination through comprehensive criteria analysis. Additionally, the analysis of the forest road network is incorporated to optimize the placement of water reservoirs. In the forest complex of Taxiarchis, Chalkidiki, Greece, 100 potential reservoir sites were identified and prioritized based on factors such as fire risk, proximity to existing water sources, and coverage area using optimal pathways. The study’s findings demonstrate that by establishing 34 water reservoirs, firefighting forces can access a replenishment point within a 5-min travel time. The conclusions underscore the efficacy of this methodology as a valuable decision-making tool for sustainable wildfire prevention planning. This approach contributes to allocating resources judiciously, effectively mitigating the wildfire risk in Mediterranean forest ecosystems, and therefore promoting sustainability.

The forest road network contributes to all aspects of the management and protection of natural ecosystems, such as fire protection and access to settlements, infrastructure and forest recreation. This has led to a constant demand for new roads and increased road density in forest areas. However, due to the environmental impact of such roads, a tool that takes into account all the parameters that they affect and evaluates the spatial distribution of forest-road-induced disturbance is needed. The present research highlights a multi-criteria evaluation (MCE), based on a spatial approach that utilizes geographical information systems (GIS), for estimating both the impact of the forest road network and the absorptiveness of the natural environment for that impact. The University Forest of Taxiarchis, Greece, was selected as it combines both timber production and recreation characteristics. Primary data were collected through the management plan for the area and the road network was categorized. A variety of factors regarding forestry, wood extraction methods and production, and social and topographical criteria were examined and scored based on their weighting factors. The results regarding the impact and the absorptiveness were analyzed in order to assess the spatial disturbance. The analysis showed that the spatial environmental impact of the forest roads is crucial and that MCE methods should be applied in environmental impact assessment (EIA) in order to support decision-making systems (DMS) for new road construction and to enhance environmental integration.

With the increase in population and commercial development, urban development has led to a decrease in natural vegetation and an increase in solid surfaces, which negatively affect the environment. Maintaining green spaces in cities is emerging as a critical intervention for improving living conditions. This research, conducted in Thessaloniki, revealed that citizens face problems in using green space, which needs to be addressed. Through questionnaires distributed online, we examined citizens’ concerns about urban green space, including the peri-urban forest of Thessaloniki and its cities. The need for regeneration and new green networks is highlighted, as well as the importance of citizen participation in the management of these spaces at the local level. The analysis of the data results in proposals for action, including the regeneration of green spaces, their interconnection with cycle paths and pedestrian walkways, and the creation of a network of applications to inform citizens. These proposals are important for improving the environment and enhancing sustainability in urban development.

This study proposes a sustainable ecotourism framework for the development of semi-mountain and mountain regions of Paiko in Greece, focusing on the strategic design and ranking of trail paths using the multi-criteria decision-making (MCDM) VIKOR method. Aiming to balance environmental conservation with economic benefits, we designed 19 trails paths and allocated signage for resting and recreation facilities. The trail paths were assessed based on criteria such as length, difficulty, scenic appeal, and accessibility. This approach identified key trails that combine scenic beauty with infrastructure suitable for a broad range of visitors, thereby enhancing sustainable tourism appeal. Stakeholder engagement was integral to shaping the trail network, ensuring that the selected paths reflect local values and priorities. This study highlights how the VIKOR method can optimize resource allocation by ranking trails according to their environmental and visitor-centered attributes, supporting regional economic growth through ecotourism. This framework offers a replicable model for other mountainous regions seeking to harness ecotourism’s potential while preserving natural ecosystems. The findings demonstrate the capacity of well-planned trail networks to attract nature-based tourism, stimulate local economies, and respond to the rising post-pandemic interest in outdoor recreation, while promoting long-term conservation efforts. This approach offers a replicable model for the sustainable development of mountainous and semi-mountainous areas in Greece and beyond.

Forest road network planning and development is important in providing accessibility to remote forest areas for timber harvesting, transportation to markets, and recreational activities, as well as preventing environmental degradation, soil erosion, water pollution, and an increased risk of forest fires and wildlife habitat fragmentation. Within the context that careful forest road transportation planning and design promotes sustainable forest management and development, this paper develops a multilayer network model for supporting sustainable forest transportation development. The model builds on a total environment conceptualization and the network paradigm, and it is composed of several layers, each containing information from an environmental aspect or a forest road network land use. By using community detection analysis from network science, the model provides insights into the decomposition of the forest network into functional areas, highlights the importance of places that connect different communities to maintain market integration, and provides a list of policies and good practices for the resulting communities. Overall, this paper presents a quantitative methodological framework that can be used for sustainable forest transportation.
