    sustainable forest management
    Opis:
    The aim of the presented research was to analyse the efficiency of forest management as an approach to promote sustainable multifunctional forestry. A total of 17 Regional Directorates of State Forests (RDSFs) in Poland were studied with the use of data envelopment analysis (DEA). This method has been proposed and tested using criteria and indicators (C&Is) as inputs and outputs of the created models. The research process was divided into two stages: first, we analysed the efficiency of simple DEA models and models with additional variables, which allowed us to determine the major models providing the best combination of efficiency evaluation criteria. Second, we used these models to assess the efficiency of sustainable management of forests by RDSFs. According to our results, RDSFs were found to be highly efficient in converting resources into production and nonmarket results. Nevertheless, the implementation of sustainable development principles requires further actions, in order to fulfil all ecological, economic, and social functions in a more effective way. They are connected with the necessity to increase the areas of both protective forests and promotional forest complexes. Thus, the results of this study might be a valuable source of information for the planning process of forestry services at the strategic and operational levels.

    Opis:
    The conception of sustainable development has been implemented into practice in numerous economic sectors, including forestry. Forest ecosystems are extremely important in the global ecological system, therefore maintenance and appropriate management of forest resources according to sustainable development principles have engaged a great deal of attention. The concept of sustainable forest management (SFM) encompasses three dimensions: ecological, economic and social. A powerful tool to promote SFM are criteria and indicators. The aim of the article was evaluation of SFM in Poland, using one of the methods proposed by the Food and Agriculture Organization (FAO). According to data available, Polish forestry has a number of advantages: Poland has avoided the problem of deforestation, forest area has been permanently increasing, there has been observed improvement of forest health and vitality as well as a significant share of forests has carried out protective functions with no impact on timber production. Poland’s model of SFM is an adaptive process of balancing the ever-changing set of economic, environmental and social expectations. Such a complicated undertaking requires constant assessing and adjusting forest practices, in response to new circumstances, scientific advances and societal input.

    Opis:
    Purpose of the work: Mountainous areas, with altitude over 700 m, intense relief and slopes between 16–20%, cover 43% of Greece and they are usually characterized by low population density and long-term unemployment. The Greeks have a dependent connection among environment, economy and society as the history illustrates. Many of Greece’s historic, cultural landscapes and native ecosystems have been degraded or isolated over the years. There is scientific evidence that Greece’s natural/semi-natural forested areas cannot be sustained without watersheds, ridges and other natural corridors that connect its native landscapes and ecosystems. Logging systems are really ancient by using often only mules or horses. The aim of the work is to estimate how harvesting systems should be technologically upgraded improving forest work and social wellness maintaining at the same time ecological sustainability. Approach: The study area is held at Samarina region, a mountainous area of Northern Pindos in Greece. Social data were collected with questionnaires and local visits for better understanding of human resources for forest authorities and other administrative information’s. DTM, Forest Inventory data and other GIS data have been derived by paper maps and previous studies. A registration of road-net and human resources within the protected area of Valia Kyrna and their contribution as factors for the sustainable development was used.The development of a Spatial Decision Support System that can concern all the conditions that are need in order to make an estimation of the optimal way of harvest a stand is really a challenge. Expected results: A GIS program is a powerful decision support tool in order to give the opportunity to the offices of Forestry to choose the optimal way of harvesting a stand and also to realize visually the effect’s of such a kind of work; that is going to be held to the inhabitants and to the tourists of the area. Conclusion: The potential of social and ecological factors is examined as it concerns the promotion of the protected area within sustainable rural development. Advantages of registration in the form of a spatial tool, especially when many types of information participate, are presented.

    Can payments for ecosystem services contribute to sustainable development in the Brazilian Amazon?

    Opis:
    The Brazilian Amazon supplies the world with several forests ecosystem services, many of which are essential to sustain human life on earth. Nevertheless, the Amazon is threatened by deforestation and degradation implying in reductions on the provision of these. According to economic theory, as ecosystem services are positive externalities and public goods, agents do not take into consideration the costs and benefits of their consumption and production of ecosystem services into their economic decisions. To address this problem payment for ecosystem services – PES – emerged, aiming to provide a source of income to the poor people living in forest areas, stimulating them not to deforest, and making agents who are indebted with the nature pay for their overconsumption of ecosystem services. There is still controversy about possible impacts of the instrument. This article accesses the potentials of PES to contribute to sustainable development in the Brazilian Amazon using the three goals related to sustainable development proposed by the ecological economics theory: efficient allocation, fair distribution, and sustainable scale. The study shows that PES as a pure market approach is unlikely to solve neither the scale nor the distribution problems. Therefore, for PES to achieve sustainable development, markets for ecosystem services should first be constrained by a maximum sustainable scale. Then, measures should ensure fair distribution in second place. Only after these questions have been tackled, it is desirable that agents interact in the ecosystem services markets to lead to an efficient allocation of resources.

    Opis:
    The issue of sustainable tourism within valuable natural areas has been extensively discussed ever since the emergence of sustainable development philosophy in the 1990s. In view of growing public interest in nature recreation and tourism development, the importance of addressing this subject matter has hitherto increased significantly. The main objective of the present paper was to offer a tool for supporting development and promotion of sustainable tourism in Poland’s forests managed by the State Forests – National Forest Holding. GIS technology, and specific tools for network analysis were used in the project. During task realization, only free and open software sources were used. The work was performed based on the example of the Forest District Żołędowo (Regional Directorate of State Forests in Toruń, Poland) with the use of District’s spatial data resources. A web application was created to present information about tourist attractions and infrastructure on an interactive map with tools for route planning. As a result, there has been developed the web mapping application which provides general access to tourism related information and enables planning touristic routes by pre-specified criteria. Implemented routing algorithms can help traffic management and further protection of the areas vulnerable to anthropogenic pressures. The system created not only promotes attractive tourist sites but also, supports targeting tourist traffic, and accordingly – adds to the progress of sustainable tourism.
