    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:
    Site and situation specific assessments of ecosystem services are crucial to sustainably conserve and manage the Chilmo forest. In this specific study, an attempt has been made to identify how local communities depend on Ecosystem services and on other stakeholders involved in sustainable forest management. The study triangulated primary data collection methods such as field observations, household surveys and key informant interviews. Secondary data was also used to support and verify the primary data. SPSS version 20 software and Microsoft excel were then applied to describe the socioeconomic characteristics of the study population’s households. Data collected through discussions and observations was analyzed qualitatively. Four forest ecosystem services (provisioning, regulating, habitat and cultural services) were identified in the study area. Even though agriculture is the main economic activities, sample respondents earn money from diverse sources such as from homestead, wood lots, honey production, petty trade and from the selling of timber and non -timber forest products, from forest dividends and other forest related employment. Chilmo forest, on average, contributes more than a third of total annual income of the sample households. Surprisingly, almost all sample respondents participate in fuel wood collection, both for household consumption and market. Similarly, fuel wood collection generates the highest income, compared to other activities, because fuel wood is the sole source of energy in the study area. Therefore, provisioning services are the main source of livelihood and subsistence incomes for local communities. The findings greatly contribute towards the management of the Chilmo forest and will be used as input for further valuation work.

    Opis:
    Mountain forests are facing substantial changes. The need to adapt forest management to climate change is overlaid by the consequences of demographic changes that alter the form of land use profoundly. The European policy is aware of the challenges and supports mountain regions by the Regulation for Rural Developments and other strategies. Regional efforts of the Forest Authorities account for the changing ownership structure in order to ensure sustainable forest management and the provision of the dependent ecosystem services.

    Opis:
    Some alien woody species used in commercial forestry become invasive and, as invaders, cause major problems in natural and semi-natural ecosystems. However, the deliberate introduction of aliens can bring unintended negative changes also within areas of their cultivation. This paper presents the effects of the intentional introduction of the North-American Quercus rubra in European mixed Scots pine-Pedunculate oak forests (POFs): Querco roboris-Pinetum (W. Mat. 1981) J. Mat. 1988. Phytosociological data from field research combined with GIS data analysis of the current distribution of Northern Red oak in the studied habitat were used to determine the composition and structure of forest communities in plots with and without Q. rubra participation. The results show that Q. rubra significantly reduces native species richness and abundance, both in old-growth and in secondary (post-agricultural) forests. Not one resident vascular plant benefits from the introduction of Northern Red oak and only a few are able to tolerate its co-occurrence. The natural restocking of all native woody species is also strongly limited by this alien tree. The introduction of Northern Red oak significantly limits the environmental functions of the POF ecosystem and weakens its economic and social aspects. However, its further cultivation is justified from an economic point of view, as the essential function of the studied forests is commercial timber production, and the introduction of this fast growing alien tree supports the provisioning ecosystem services. A clear description of the level of trade-off between the accepted negative and positive effects of the introduction of Q. rubra on forest ecosystem services requires further interdisciplinary studies.

    Opis:
    In the face of growing urbanised areas, the presence of forests and their appropriate shaping is a key challenge for contemporary urban planning. The importance of forests is largely identified with natural, economic and social functions in non-urban areas; however, forests are of vital value in urbanised areas. This article explores young Polish urbanites’ awareness of the role forests play, and submits diagnoses of the forests multidimensional benefits and their functions in Poland’s urban areas. Moreover, the research is based on the premise that the management of urban forests must ultimately lead to the satisfying of social needs. Based on empirical research, the perceptions of the value of urban forests as assessed by young people (students) in the Śląskie Voivodeship are presented, leading to the authors’ postulation that urban forests are underestimated resources. Furthermore, the study suggests that young Poles do not recognise the multi-beneficial aspects of urban forests; and the authors indicate feasible directions for local policy to achieve sustainable development. The final statements argue that in the face of serious threats to the functioning of Earth’s ecosystem, a campaign for the presence of forests and green spaces in cities is necessary.
    W obliczu rosnącej powierzchni terenów zurbanizowanych obecność lasów miejskich i ich odpowiednie kształtowanie jest jednym z kluczowych wyzwań dla współczesnej urbanistyki. Znaczenie lasów utożsamiane jest głównie z funkcjami przyrodniczymi, ekonomicznymi, czy społecznymi na terenach pozamiejskich. Jednocześnie tereny leśne niosą istotną wartość na terenach zurbanizowanych. W wielu krajach obserwujemy rosnącą świadomość znaczenia lasów dla zdrowia fizycznego i psychicznego mieszkańców oraz prawidłowego kształtowania się relacji społecznych. Sąsiedztwo lasów pozytywnie wpływa na jakość życia mieszkańców miast. Interesujące poznawczo jest na ile mieszkańcy miast w Polsce mają świadomość roli lasów w miastach oraz w jaki sposób z nich korzystają. W artykule dokonano diagnozy wielowymiarowych korzyści funkcji terenów leśnych na obszarach miejskich. W oparciu o badania empiryczne przedstawiono percepcję wartości lasów miejskich w ocenie młodego pokolenia województwa śląskiego (studenci). Na podstawie przeprowadzonej analizy roli lasów autorzy zaprezentowali kierunki wsparcia polityki lokalnej ukierunkowanej na zrównoważony rozwój. Zdaniem autorów, w obliczu poważnych zagrożeń dla funkcjonowania ziemskiego ekosystemu niezbędna jest kampania na rzecz obecności lasów i drzew w naszych miastach.

    Opis:
    Ectomycorrhizal (ECM) fungi and their symbiotic associations with forest trees are among major drivers of key ecosystem functions such as carbon and nitrogen cycling, plant nutrient and water uptake from soil, plant-plant facilitation/competition and diversity regulation via common mycorrhizal networks. Through their functional traits and interactions with both abiotic and biotic environment, they also significantly affect the process of open land colonization by trees as well as vegetation succession coupled with soil and ecosystem development. Here we review the role of ECM fungi in the early primary and secondary succession following major anthropogenic disturbances. Based on the examples of mine spoils and post-agricultural lands, we demonstrate key ecosystem services provided by ECM fungi in the processes of forest restoration. We point out ecological mechanisms and adaptations which underpin ECM fungal community successional interactions, particularly life histories, dispersal, spatial structure, host preferences, and sensitivity to environmental filters. We emphasize the need of better understanding the role of ECM fungi in the forest restoration practice as it seems crucial for afforestation success and biodiversity rehabilitation. Thus, ectomycorrhizal traits should be a prime consideration in afforestation and carbon sequestration polices, sustainable forest management and biodiversity conservation practices.
