    Mastomys natalensis
    Opis:
    Lassa fever is an acute viral disease that is endemic in West African countries of Nigeria, Liberia, Sierra Leone and Guinea. Since the first case was reported in Lassa town Nigeria in 1969, Mali 2009, Ghana in late 2011 and serological evidences of the virus was reported in Togo and Benin in 2014 the virus has assumed an endemic proportion in West Africa. Deforestation which is the deliberate disruption of the natural forest ecosystem has been implicated as a major cause of the virus holding to the fact that the natural habitats of the rodent host have been tampered and hence they seek refuge in human homes. Most research work have been centered on the epidemiology ,hygiene and mode of transmission of the zoonotic virus without critical consideration of habitat destruction of this rodents that negate their relocation to human homes in search of food and alternative shelter. This review article aims to raise awareness on the urgent need to control deforestation acts in order to prevent further outbreak of Lassa fever.

    Opis:
    There are ample facts that the whole world is facing an ecological crisis by reason of heavy deforestation. Thus, this study assesses the influence of deforestation on some selected villages in Borgu Local Government Area, Niger State. Data were collected from members of the community using a set of structured questionnaire. This was then analyzed using descriptive statistics (percentages and frequency count). Findings reveal that the major occupation is trading (33.3%), followed by farming (30%). The causes of deforestation in the study area include: fuelwood removal (31.7%), urbanization (25.0), logging (20.0%), subsistence farming (15.8%), population growth and overpopulation (3.3%), commercial farming (2.5%) and inequitable distribution of wealth and power (1.7%). Global warming (31.7%) was the major effect generated by deforestation in the study area, followed by soil erosion (24.2%). Encouragement of better agroforestry practices (30.8%) was seen as the major strategy for reducing deforestation by the respondents. Other best practices include: afforestation (27.5%), public enlightenment (13.3%), enforcement of forest land and policy (12.5%), forest education (8.3%), forest conservation and preservation (7.5%).

    Opis:
    Charcoal production in Nigeria is a growing source of concern for government and forestry institutions because of its perceived impact on the environment. The agreed impact is deforestation, i.e., the clearance of indiscriminate cutting of forest trees. Forest degradation associated with charcoal production is difficult to monitor and overlooked and under-represented in forest cover change and carbon emission estimates. Emissions of greenhouse gases a consequence of deforestation from charcoal production in tropical ecosystems in 2009 are estimated at 71.2 million t for carbon dioxide and 1.3 million t for methane. Trees used for charcoal production are Vitellaria paradoxa, Ficus sur, Tectona grandis, Khaya ivorensis, Bombax buonopozense just to mention a few. This review aims to further discredit the act of indiscriminate forest tree falling for charcoal production which have proofed by various works as a promoter of deforestation.

    Forests are one the main natural factors that regulate and determine climate, weather patterns and amount of CO2 of an area. With rapid industrialization and rapid urbanization there is a significant increase in deforestation and as a consequence rise in global mean surface temperatures. Rapid and unchecked cut down of forest cover has resulted in some of the worst disasters during the last decades. This paper focuses on studying the role of deforestation, its influence on climate change phenomena and its consequences in Pakistan.

    Opis:
    Mountain forests constitute one of the most diverse ecosystems, not only in Europe but also all over the world. Mountain ranges, which frequently encompass multiple countries, constitute a unique link between various natural areas, which are very often completely different from the historical point, or which are characterized by different use and management types. Although the role of mountain forests is relatively well recognized nowadays, in the distant past, these areas were poorly penetrated, mainly due to the unfavourable climate and natural topography, which discouraged not only from settling down but also from moving around. Despite the fact that mountains had been the object of interest of mining, weaving, and glassmaking industries for hundreds of years, dramatic changes in the stands in these areas were sealed by the industrial revolution in the 18th and 19th centuries. The purpose of this paper is the analysis of forest dieback process in the mountain ranges of Sudetes and Western Carpathians placed in Poland. Stress factors have been divided into three main groups, however, it should be remembered that it is a very simplified division and some factors could be partially found in the anthropogenic, as well as biotic, and even abiotic factor groups. Neither the beginning nor the end of deforestation process was defined precisely in the study, which was deliberate in taking into account constant changes in the ecosystems. Generally, three periods may be distinguished here, regarding the spruce forests dieback process. Typically anthropogenic deforestation, caused by the industrialization of the areas during the industrial revolution and earlier, deforestation in the years 1970–1980 and partially before the year 2000 (Western Carpathians) caused by a set of various stress factors and the latest period, that is, generally understood climate change. The last several years have particularly contributed to the expansion of detailed knowledge about the dependencies and the influence of abiotic, biotic, and anthropogenic factors on the health condition of spruce trees. Although models have already been developed, which describe the course of insect outbreaks, the growth and health condition of spruces, or climate factors, no model has been developed so far that would allow to depict the process of hitherto deforestation, and to enable modelling the forthcoming changes. It seems that the development of such tool, not only from the forest management point of view, would constitute a milestone on the way to precision forestry.

    Opis:
    The aim of the study is to present – in the perspective of up to 2030 – plans about deforestation in the area administered by the State Forests, formulated at the level of communes and judged on the level of provinces (voivodeships), as well as plans for land reclamation into forests, formulated at the level of counties. The data was collected in 2013−2014 in a survey, which included the following groups of respondents: mayors of all rural and urban−rural communes, heads of all rural counties and marshals of provinces. According to information provided by 34.4% of communes, it is planned to cease the production on at least 517.1 hectares of forests, located in 64 forest districts. In relation to requests for deforestation, marshals of provinces presented various approach to their assessment, but always within the limits of applicable law. On the other hand, according to the data provided by 57.3% of counties, land reclamation into forests is planned to reach at least 498 hectares in 57 forest districts. Deforestation and forest reclamation affect both the landscape and the level of forest cover of the country. The results show a greater concern of commune heads about deforestation than it is in the case of heads of counties about land reclamation into forests. The balance in these activities proportion would be at least a positive natural, economic and social achievement. The processes of deforestation, afforestation, forest management and land restoration into forests – directly affecting the quality of the landscape – are important for assessing the implementation of the European Landscape Convention in Poland. Taking into account the current level of afforestation in Poland, it is unlikely to achieve the forest cover of 33% by 2050. Therefore, it is important to control the size of deforestation and to increase the scope and pace of land reclamation into forests.

    Opis:
    Recently, Google Earth Engine (GEE) provides a new way to effectively classify land cover utilizing available in-built classifiers. However, there have a few studies on the applications of the GEE so far. Therefore, the goal of this study is to explore the capacity of the GEE platform in terms of land cover classification in Dien Bien Province of Vietnam. Land cover classification in the year of 2003 and 2010 were performed using multiple-temporal Landsat images. Two algorithms – GMO Max Entropy and Classification and Regression Tree (CART) integrated into the Google Earth Engine (GEE) platform – were applied for this classification. The results indicated that the CART algorithm performed better in terms of mapping land use. The overall accuracy of this algorithm in the year of 2003 and 2010 were 80.0% and 81.6%, respectively. Significant changes between 2003 and 2010 were found as an increase in barren land and a reduction in forest land. This is likely due to the slash-and-burn agricultural practice of ethnic minorities in the province. Barren land seems to occur more at locations near water sources, reflecting the local people’s unsuitable farming practice. This study may provide use-ful information in land cover change in Dien Bien Province, as well as analysis mechanisms of this change, supporting environmental and natural resource management for the local authorities.

    This article describes the role of forests in climate change policy. It examines the inclusion of the forestry sector into the UNFCCC and the Kyoto Protocol, focusing mainly on two concepts currently being developed in international debates: LULUCF (Land Use, Land Use Change and Forestry) and REDD+ (Reducing Emissions from Deforestation and Forest Degradation). In addition to providing an overview and analysis of these concepts, the article also outlines their potential consequences for forests in Poland and reviews the EU actions to include the forestry sector into European climate policy. Finally, some issues related to forest use for carbon offsetting and energy generation are discussed as well.

    Opis:
    Erosion is a natural phenomenon which constantly changes the shape of the Earth’s surface, yet it is regarded as a very serious harmful factor by people in view of their economic and investments activities. Ski slopes are a special example of areas with a serious erosion hazard due to a permanent deforestation, considerable longitudinal slopes, engineering works, levelling ski slopes, but also because of abundant surface runoff. The aim of the research was to compare the extent of potential soil erosion in deforested areas intended for ski slopes, with various anti-erosion measures implemented, as well as to discuss the possibility of RUSLE erosion model application under these conditions. The researched objects were ski runs on the eastern slopes of Mount Jaworzyna Krynicka (The Beskid Sądecki Mts.). Potential erosion was computed in the areas of seven ski slope segments in four variants of the area cover and applied anti-erosion measures. Some computational data (the ski slope area, average slope gradients, soil granulometric composition) were obtained from the Forest Digital Map and Digital Terrain Model, whereas numerical indicators used for the model were established on the basis of the subject literature. Under presented conditions, potential erosion losses were greatly diversified. The biggest losses, expressed as erosion losses factor A, have been indicated for variant I (naked soil, without anti-erosion measures) and varied from ca. 18 to ca. 36 Mg•ha-1•year-1. Sodding ski slopes dimin ished potential erosion to 4.5% of the value obtained for the comparative variant (variant I), while shortening of the surface runoff length without sodding may reduce potential erosion losses to ca. 20÷25%. Combination of both measures may significantly reduce the erosion in these areas (to ca. 0.04%). The obtained results are analogous to other authors’ findings.

    Opis:
    The main aim of this study was the reconstruction of the environmental changes (identifiable at this stage of research) resulting from large-scale charcoal production for the needs of historical water-powered metallurgy in selected sites in the Mała Panew basin. The identification of the remains of charcoal hearths was carried out by analysing shaded relief models. Shaded relief models were created from data from Airborne Laser Scanning (LIDAR). In order to verify the charcoal hearth remains identified in digital images, ground proofing was carried out. The charcoal hearth remains were subjected to sampling. Fragments of charcoal were extracted from the samples, which were then sent for analysis to identify tree species. In order to determine the age of chosen charcoal hearth remains, 10 charcoal pieces were submitted for radiocarbon dating. The following taxa were identified: Scots pine (Pinus sylvestris), alder (Alnus sp.), birch (Betula sp.), oak (Quercus sp.), Norway spruce / larch (Picea abies / Larix sp.), Silver fir (cf. Abies alba) and ash (Fraxinus excelsior). The taxa identified are dominated by Scots pine (56%). This research demonstrates that valuable wood of deciduous species might have been overex-ploited at the initial stage of metallurgical production and very quickly exhausted, being replaced by fast-growing coniferous species. The excessive exploitation of the forests might have had negative environmental effects such as the transformation/modification of the species composition of the forest cover, significant deforestation of exploited areas, intensification of floods or the initiation of aeolian transport of sands. All the charcoal hearth remains investigated date to the period from 1677 to 1957 AD.

    Opis:
    The aim of the study was to determine the effect of deforestation caused by environmental pollution on the chemical composition of stream waters draining the small catchments located in the Skrzyczne massif (Beskid Śląski, southern Poland). In the 1950−60s this area was subjected to heavy anthropogenic pressure with excessive deposition of sulfur and nitrogen compounds. It resulted in the damage to the stands and deforestation of the ridge fragments of the studied area. The study was conducted in the catchment of the Malinowski Stream and its two subcatchments: forested and deforested in 2013. Waters of the studied streams characterized by low conductivity and mineralization. In the ridge subcatchments they were slightly acidic and in the main catchment – slightly alkaline. In all catchments anions were predominated by sulfates – with the largest in the deforested catchment (31% mval/L). Also nitrates had very large share in the structure of the chemical composition of water, particularly in the forested catchment (15% mval/L). Interestingly, there were low levels of bicarbonates, particularly in the ridge catchments, with their share lower than sulfates and nitrates. Cations in all streams were predominated by calcium. The structure of the chemical composition of water of the Malinowski Stream, expressed by the average share of individual ions was as follows: SO4−HCO3−NO3−Cl−F−Ca−Na−Mg−K−NH4, and in the case of streams draining small ridge catchments: – SO4−NO3−HCO3−Cl−F−Ca−Na−Mg−K−NH4. Conductivity of water decreased together with increased water levels in streams during floods. In the deforested catchment this decrease was more evident. The reaction of nitrate concentration to the increase in water level was however different, as in the stream draining the forested catchment it decreased sharply, while in the deforested catchment it decreased slightly or remained at the similar level. In the dry periods the chemical composition of waters of the examined streams were subject to far less change than during the floods, with the changes of e.g. conductivity being much higher in the stream draining the forested catchment.

    Opis:
    Głównym celem opracowania jest zdefiniowanie wyzwań dla zrównoważonej gospodarki leśnej w Chinach. Komunistyczny rząd dąży do przywracania podstawowych funkcji ekosystemu poprzez sadzenie drzew. Dąży do zwiększenia różnorodności biologicznej i odwrócenia procesu pustynnienia. Określa działania, które mogą być podjęte w celu zapobiegania wylesianiu i degradacji gruntów. Polityka leśna skupia się na ochronie środowiska jak również podkreśleniu ekologiczno-przyrodniczych, społecznych i gospodarczych funkcji leśnych ekostemów. Drzewa spełniają funkcję ochronne pochłaniając i neutralizując substancje toksyczne, tj. dwutlenek węgla w procesie fotosyntezy. Obecnie przed Chinami stoi konieczność  poprawy skuteczności w zakresie wdrażania i egzekwowania prawa ochrony środowiska na szczeblu lokalnym, jak i kwestia systematycznego podnoszenia świadomości ekologicznej wśród obywateli Państwa Środka.
    This paper aims at assessing the challenges for sustainable forest management in China. The Communist government is going to improve the essential ecosystem by restoring severely degraded forests. It wants to enhance the biodiversity of natural systems as well as prevent, control and reverse desertification. It defines actions that could be taken to prevent deforestation and land degradation. The forest policy focuses on environmental protection and emphasizes the ecological and socio-economic functions of forests resources. It mainly underlines their protective and regulatory functions to sequester carbon by capturing carbon dioxide from the atmosphere. Currently, China has to primarily improve the implementation and enforcement of existing laws and regulations at the local level as well as raise environmental awareness of Chinese community.

    Opis:
    Mitigation and adaptation are the main strategies to address climate change. Both of them are interrelated instruments and key elements of an integral approach to tackle the phenomenon. This interrelation is particularly strong in the land use sector, an area in which practically any policy has a significant effect on the goals of both strategies. Yet, in practice, mitigation and adaptation are treated as two different instruments. A poor understanding about the interactions between the mentioned strategies remains as a barrier to implement the integrated approach. To contribute to fill-in this knowledge gap, a hypothetical ecologic-economic system simulated under deep uncertainty was used to test environmental and welfare implications of different policy configurations. Taking the unregulated economy as a benchmark, the outcomes of the mentioned interventions were classified as synergies or different forms of trade-offs. Results indicate that measures based on internalization of externalities overcame monetary compensation schemes. Moreover, when externalities were corrected, synergies were more frequent and associated to higher environmental and welfare gains. Furthermore, the policy configuration that exhibited best synergic properties was an intervention integrating mitigation and adaptation measures. This indicates that synergies may be more accessible than previously considered, however, current policy approach and incentives may not be the best tools to trigger them.

    Opis:
    The Global Environmental Monitoring Index (GEMI) represents a vegetation index that allows for making analysis. The index is not that sensitive to atmospheric effects. GEMI has been applied for the investigation of disruptions in the coniferous forests in Pernik Province, which is situated in the western parts of Bulgaria. The basic data comes from Landsat 8 and Corine Land Cover. The results of the study show that the index performs well in the distinguishment of broad-leaved vegetation from the coniferous one. At the same time the index doesn’t always provide satisfying results when it comes to deforestation. In conclusion GEMI provides good results, yet it’s use should be controlled and supported by other vegetation indices.

    Opis:
    Forest plantation is reckoned to accounts for 7% of total global forest cover and has the potential to provide 75% of the global industrial round wood supply. The study analyzed forest resource use trend, mapped out areas of high biodiversity conservation,and made recommendations to promote and sustain large-scale plantation development against the background of anthropogenic pressure on vulnerable ecosystems and biodiversity management. The methodology adopted for the study involved the application of geographic information system (GIS) and remote sensing techniques, field survey and community interactions. Major findings of the assessment include substantial land use/land cover conversion from one category to another within the past 20 years as a result of agricultural expansion, urbanisation, charcoal production and wood fuel harvesting; dense woodland and riverine forest experienced decline for the 20-year period whilst agriculture open woodland/grassland and settlement were appreciated; floral diversity was high in the dense woodlands with low regeneration potential because of persistent annual wildfires; significant socio-economic and environmental impacts resulting in the conversion of woodlands and removal of riverine vegetation leading to drying out of streams; charcoal production and shifting cultivation leading to decrease in soil productivity and poor crop yields that promotes poverty amongst the inhabitants.

    Opis:
    The article presents the findings of research on attitudes of man toward the problem of destroying of tropical rainforests. The empirical measurement was obtained in the years 2014–2015 from a representative sample of 1,000 inhabitants of Kuyavian-Pomeranian Voivodeship. The respondents were asked to take a stance toward four statements which express approval or disapproval of the clearance of rainforests. Axiologically and normatively, the statements were adjusted either to anthropocentrism or biocentrism, which results from the division accepted in environmental ethics. The results indicate that a substantial majority of the respondents reject individualistic anthropocentrism, according to which rainforest clearance may be justified by the welfare and interests of particular individuals. Simultaneously, they give their full approval for biocentrism statements whose content voices an objection against the destructive impact of humans on the functioning of the tropical jungle. Most respondents allow for the clearance of tropical rainforests only when it serves the interests of the whole society and future generations.
    Artykuł prezentuje wyniki badań nad postawami człowieka wobec zjawiska niszczenia lasów tropikalnych. Pomiaru empirycznego dokonano w latach 2014-2015 na reprezentatywnej, liczącej 1000 osób, próbie mieszkańców województwa kujawsko-pomorskiego. Ankietowani zostali poproszeni o ustosunkowanie się do czterech stwierdzeń, które w swej treści wyrażają zgodę lub brak zgody na wyrąb lasów tropikalnych. Pod względem aksjologicznym i normatywnym stwierdzenia te zostały dopasowane do przyjętego w etyce środowiskowej podziału na stanowiska antropocentryczne i biocentryczne. Uzyskane wyniki wskazują, że zdecydowana większość respondentów odrzuca antropocentryzm indywidualistyczny, zgodnie z którym wycinka lasów tropikalnych może być uzasadniona dobrem i interesem poszczególnych jednostek. Jednocześnie wyrażają oni wysoką aprobatę dla stanowisk biocentrycznych, których treść zawiera sprzeciw wobec destrukcyjnej ingerencji człowieka w funkcjonowanie tropikalnej puszczy. Niemniej jednak, większość osób badanych dopuszcza możliwość wyrębu lasu tropikalnego jedynie wówczas, jeśli służy to dobru całego społeczeństwa i przyszłych pokoleń.

    Opis:
    Mangroves and the associated shoal forest known as ‘restinga' are ecosystems of great ecological relevance that play a significant role in the protection of the coastline in tropical regions. In Brazil, the coastal region has been severely affected by urban expansion. The Paranaguá Port, located in Paraná State (Brazil), is the fourth most important Brazilian port in throughput, and is located in an estuarine region which features large mangrove forests. An historical assessment of its inner access channel dredging rates was made to assess the impacts that the expansion of the Port in the last 30 years may have caused to the ecosystem. In the following, the historical data concerning the dredged volume in the inner access channel was compared to the mangrove and the shoal forest associated variation, aiming to establish a potential correlation between vegetation and siltation in the inner access channel to show as the preservation or restoration of specific ecosystems has potential to Nature-Based Solutions.

    Opis:
    The land use sector is an area with high potential to pursue mitigation and adaptation goals alike. However, due to the complexity derived from managing landscapes with multiple objectives and the lack of tools to assess the outcome, this potential is presumably subtilized in practice. In order to contribute to filling in this knowledge gap, this paper analyses climate policy integration – the joint implementation of mitigation and adaptation measures – in the presence of ecological thresholds. Based on a hypothetical, yet realistic, economic-ecological system, the synergic properties of different isolated and integrated policy configurations were analysed using a dynamic optimization framework and simulation tools. The results indicate that, regardless of specific circumstances (e.g. observing or not noticing a regime shift), the configuration which better complied with the definition of a synergy, corresponded to a cross sectorial approach: an intervention involving coordination between agriculture and forestry. This result suggests that harmonization among the elements that compose the land use sector is the main source of an enhanced policy outcome. Thus, effective integration requires looking at the land use sector as an entity (e.g. a landscape) rather than isolated components (e.g. agriculture and forestry sectors).
    Sektor użytkowania gruntów jest obszarem o dużym potencjale do realizacji i łagodzenia celów. Jednak ze względu na złożoność wynikającą z zarządzania krajobrazem z wieloma celami i brakiem narzędzi do oceny wyników, potencjał ten jest prawdopodobnie wysubtelniony w praktyce. Aby przyczynić się do wypełnienia tej luki w wiedzy, niniejszy artykuł analizuje integrację polityki klimatycznej - wspólne wdrażanie środków łagodzących i dostosowawczych - w obecności progów ekologicznych. Opierając się na hipotetycznym, realistycznym oraz ekonomiczno-ekologicznym systemie, analizowano synergiczne właściwości różnych izolowanych i zintegrowanych konfiguracji polityk przy użyciu dynamicznej struktury optymalizacji i narzędzi symulacyjnych. Wyniki wskazują, że niezależnie od konkretnych okoliczności (np. Obserwacja lub niezauważenie zmiany reżimu), konfiguracja, która lepiej odpowiadała definicji synergii, odpowiadała podejściu międzysektorowemu: interwencji obejmującej koordynację między rolnictwem a leśnictwem. Wynik ten sugeruje, że harmonizacja elementów składających się na sektor użytkowania gruntów jest głównym źródłem ulepszonych wyników polityki. Skuteczna integracja wymaga zatem spojrzenia na sektor użytkowania gruntów jako podmiot (np. Krajobraz), a nie pojedyncze elementy (np. Sektory rolnictwa i leśnictwa).

    Opis:
    As with many countries worldwide, Namibia is, despite its relatively small population and stable government, facing some significant environmental problems. This research sought to determine how a group of potentially influential tertiary-level students perceived the state of the environment in Namibia. To this end, a cohort of 20 preservice science teachers were interviewed to determine their perceptions of the environmental issues facing Namibia. The majority of the cohort identified deforestation as the major such issue. They also associated this concern with other problems such as soil erosion, salinity, and desertification. Some also raised concerns about global warming and associated climate change; several of the preservice teachers believed the country was already experiencing the effects of this. Although the population of Namibia is quite small relative to its area, the future teachers perceived population growth as a problem contributing to both environmental and social problems. All viewed education as key to reducing family size and alleviating social and environmental problems. However, none of the cohort made any connection between increasing patterns of consumption and environmental degradation.
    Jak wiele krajów na całym świecie, Namibia, poza względnie niewielką populacją i stabilnym rządem, boryka się z poważnymi problemami środowiskowymi. Artykuł przedstawia wyniki badań ukierunkowanych na określenie, w jaki sposób grupa potencjalnie wpływowych studentów trzeciego stopnia pedagogiki postrzega stan środowiska w Namibii. W tym celu przeprowadzono wywiady z grupą 20 przyszłych nauczycieli, aby zbadać ich postrzeganie wyzwań środowiskowych, przed jakimi stoi Namibia. Większa część respondentów stwierdziła, że głównym problemem jest wylesianie. Kojarzyli oni również zagrożenia środowiskowe z erozją, zasoleniem oraz pustynnieniem. Niektóre osoby wskazywały na globalne ocieplenie i powiązane z nim zmiany klimatyczne, kilku studentów uważało, że kraj już cierpi z powodu tych zjawisk. Pomimo że populacja Namibii jest dość niewielka w porównaniu do jej powierzchni, przyszli nauczyciele uznali wzrost liczby ludności za problem zarówno środowiskowy, jak też społeczny. Wszyscy respondenci postrzegali edukację jako klucz do zmniejszenia wielkości rodzin oraz złagodzenia problemów środowiskowych i społecznych. Jednak żaden z uczestników badania nie powiązał degradacji środowiska z umacniającymi się wzorcami konsumpcyjnymi.

    Opis:
    The world we live in has witnessed some drastic environmental imbalance in recent times. These imbalances have threatened sustainable development- which is the ultimate goal of man-environment relationship. This paper reviews the causes and effects of climate change on man and his environment with a view to using science education to solve the problems posed by climate change. Literature shows that climate change results mainly from human activities such as rapid deforestation for agricultural and industrial purposes, carbon dioxide emission from fossil fuel burning, carbon dioxide emission from burning gasoline for transportation, usage of chemical fertilizers on croplands and methane emission from animals, agriculture and arctic sea beds. The consequences of these activities include global warming, ozone layer depletion, greenhouse effect, rising sea level and acid rain. It is recommended here that the whole educational process be re-packaged to emphasize science education as a panacea for sustainable development. The argument here is that the educational institutions are the best media for the inculcation of proper morals and values. It is also recommended that teacher education programmes should allocate more funds to research in, and teaching of science in schools.

    Opis:
    Ostatnie 25 lat w Polsce cechują duże zmiany społeczno-gospodarcze, wyraźnie widoczne także w pokryciu i użytkowaniu terenu. W artykule przedstawiono charakterystykę ilościową, jakościową oraz przestrzenną zmian w pokryciu terenu, jakie zaszły w Polsce w latach 1990-2012, ze szczególnym zwróceniem uwagi na okresy: 1990-2000, 2000-2006 oraz 2006-2012. Analizy zostały wykonane na podstawie danych zgromadzonych w bazach CORINE Land Cover. Podstawowym celem badań była ocena zmian pokrycia terenu, które są następstwem zmian sposobu użytkowania ziemi w Polsce w okresie transformacji systemowej na przełomie XX i XXI wieku. Szczegółowo przeanalizowano przejmowanie gruntów rolnych i leśnych na budowę dróg oraz powiększanie terenów zabudowanych. Otrzymane wyniki pokazują, że powierzchnia zmian była stosunkowo niewielka i w żadnym z analizowanych okresów nie przekroczyła 1% powierzchni kraju. Zaobserwowano, że od 1990 roku następuje systematyczne zwiększanie terenów antropogenicznych głównie kosztem terenów rolniczych (gruntów ornych, sadów i plantacji oraz łąk i pastwisk) i zalesionych.
    The last 25 years in Poland are characterized by large socio-economic changes, clearly visible in the land cover. The article presents quantitative, qualitative and spatial characteristics of land cover changes in Poland in the years 1990-2012, with special attention paid to the periods 1990-2000, 2000-2006 and 2006-2012. The analyses base on CORINE land Cover data. The main objective of the study was to analyze the urbanization and accompanying land take of agricultural lands and forest for the construction of roads and the spread of built-up areas. The results show that the area of land cover changes was relatively small and it does not exceeded 1% of the country's territory. Since 1990 a systematic increase in anthropogenic areas is observed which is accompanying with afforestation, and decrease of arable lands.

The research aimed to substantiate the ecological and economic importance of forest resources in the Kyiv region and analyse their rational use and protection. The article shows that the Kyiv region belongs to the regions with an average level of forest cover – 592.8 thousand hectares or 22.2%. The level of forest cover is uneven in the area of the Kyiv Forest zone. It is 44%, and in the area of the Forest-Steppe, it is much lower and decreases from north to south. The use of forest resources in the Kyiv region in 2019 amounted to harvesting liquid wood of 999.5 thousand m2, and deforestation was carried out on 75.5 thousand hectares. The region’s volume of forestry works and services amounted to 8,9 million dollars, and the wood stock makes 90805,9 thousand m2. Emphasis is placed on the importance of protecting the Red Book species of plants and fungi that grow in the forests of the Kyiv region. Examples of harmful economic activity in the areas belonging to the nature reserve fund and large-scale fires in April 2020, which covered more than 3.5 thousand hectares of forests in the region and caused damage to forest fauna and flora. The studied region’s positive environmental and economic factors have been admitted by planting trees on an area of 2151 hectares and sowing seeds of forest species on an area of 67 hectares in 2020.

    Opis:
    The paper presents a hybrid classification method based on the determination of the optimal number of classes according to uncontrolled classification followed by image processing techniques of controlled classification. A criterion for determining the optimal number of classes is proposed based on the definition of averaged values differences of average spectral brightness among the classes. Space images from satellites Ikonos (2002, 2007) and QuickBird (2010) were used to study different time cuttings in the forests of the Carpathian region. A significant amount of ground observation was held for getting test information. A Hybrid Classification Method is used for different time cuttings by QuickBird satellite images and implemented in a software environment of ERDAS Imagine. In order to obtain acreage of cuttings made for the period of 2002-2007 and 2007-2010, a comparative analysis of cuttings is introduced in these time intervals and their area is determined on the basis of the digital images of polygons in the ArcGIS software environment.

    Opis:
    Nielegalne pozyskiwanie drewna oznacza, iż jego pozyskanie nastąpiło z naruszeniem przepisów kraju pozyskania. Jest to problem o charakterze globalnym, wywołujący poważne i negatywne skutki nie tylko o charakterze środowiskowym, ale również gospodarczym i społecznym. Niniejszy artykuł prezentuje instrumenty Unii Europejskiej mające na celu przeciwdziałanie handlowi nielegalnie pozyskanym drewnem na rynku Unii Europejskiej. Instrumenty te podzielone zostały na dwie grupy: wewnętrze i międzynarodowe. Następnie została dokonana analiza ich zakresu materialnego, ale również podjęto próbę odpowiedzi na pytanie, jaki jest ich charakter prawny, zarówno w prawie Unii Europejskiej, jak i w systemach krajowych państw członkowskich. Innymi słowy, czy mogą one efektywnie przyczynić się do przeciwdziałania handlowi nielegalnie pozyskanym drewnem na unijnym rynku wewnętrznym.
    Illegal logging is a significant problem of major international community concern because it has a devastating impact on some of the world’s most valuable remaining forests and contributes to tropical deforestation and forest degradation. Furthermore, it threatens biodiversity and undermines sustainable forest management, having a negative impact on poverty reduction, sustainable and inclusive economic growth and development. The article presents instruments adopted by the EU in order to combat illegal timber logging. The author describes their material scope and legal character, dividing them into two groups: internal and international legally binding instruments and soft law instruments, in order to answer the question about their legal character and position in the EU legal order and in national orders of the Member States.

    Opis:
    W opracowaniu podjęto próbę określenia wpływu różnych aktywności człowieka na stan lasów Świętokrzyskiego Parku Narodowego i jego otuliny. Do podstawowych przejawów działalności gospodarczej zaliczono starożytne hutnictwo żelaza, rozwój osadnictwa i z związane z nim rolnictwo, hutnictwo szkła, gospodarkę leśną, a także współczesny, masowy ruch turystyczny. Ustalono, że odbywały się one na dwóch etapach: 1 – okres wielofunkcyjnego, nieplanowanego użytkowania zasobów leśnych liczony w tysiącach lat(ostatnie 2000 lat) oraz 2 – okres planowej gospodarki leśnej (ostatnie 200-250 lat).
    The article attempts to determine the impact of various human activities on the state of forests of the Świętokrzyski National Park and its buffer zone. The basic forms of economic activity include ancient iron smelting, gradual development of human settlements and related to it agriculture, glass melting, forest management, as well as mass tourist movement It was stated that they were held in two stages: 1 – the period of multifunctional and unplanned using of forest resources measured in thousands of years (the last two millennia) and 2 – the period of planned forest management (the last 200-500 years).

    Opis:
    The purpose of this study was to identify the willingness of farmers to pay for small-scale irrigation (SSI) and its determinants. Additionally, this study analysed the physical water availability in the study area using 16 years’ (2004-2019) historical data of streamflow, rainfall and forest cover change. A structured questionnaire was used to collect the data from 100 farmers. A contingent valuation method was employed to elicit farmers’ willingness to pay (WTP) for irrigation water. The results show that the average WTP of farmers is US$ 215.84/ha/year. It accounts for 20% of farm revenue and is almost 20 times the water fee in large-scale irrigation systems. The study area experienced significant deforestation in the last two decades suffering a decrease of 11.72% of forest cover. It decreases the amount of stored rainwater and decreases the streamflow causing water scarcity during the dry season. Farm size, farmer income, distance to a small dam and usage of water-pump are the significant determinants. The results indicate that water scarcity caused by poor infrastructure increases the economic value of water in a SSI system.

    Opis:
    Celem badań było poznanie zróżnicowania cech teksturalnych oraz cech chemicznych osadów odprowadzonych ze zlewni tatrzańskich objętych wiatrowałem w 2013 roku. Zróżnicowanie to powiązane zostało z energią rzeźby zlewni oraz skutkami wiatrowału. W zlewniach dominowały osady złożone podczas małej dynamiki transportu, jednak dwie zlewnie charakteryzowały się pewnym udziałem (do 10%) osadów deponowanych w środowisku o większej energii. Jednak zróżnicowanie to związane jest z energią rzeźby badanych zlewni, natomiast wpływ wiatrowałów nie zaznaczył się jeszcze wyraźnie w cechach teksturalnych osadów.
    The aim of the research was to recognize the diversity of the textural and chemical characteristics of the sediments removed from the catchments of the Tatra Mts., which were affected by the windthrow event in 2013. The diversity was related to the morphometry of the catchments and the effects of the windthrow event. In catchments sediments deposited during low transport dynamics dominated, two of the catchments were characterized by some percentage (up to 10%) of the sediments deposited in the high-energy environment. However, this diversity is connected to the morphometry of the studied catchments and up to this time impact of the windthrows is not clearly reflected in the textural characteristics of the sediments.

    Opis:
    The study focused on the effects of deforestation by heavy winds and tree stand damage produced by bark beetle invasion on water chemistry of mountainous catchment of Kościeliski Stream in the Tatra National Park (southern Poland). 200 samples of stream and spring water were collected in three series: in July, August and October 2015. Water samples obtained from areas characterized by tree stand damage caused by heavy winds were found to have much higher mean concentration of nitrate (15.44 mg/L) as well as a much higher overall mean nitrate content (3.44% mval/L) than samples obtained from non−deforested areas (3.26 mg/L and 0.78% mval/L). The increase in nitrate concentration and its share in overall water chemistry was high enough that the anion sequence for the deforested areas became altered from HCO3>SO4>NO3>Cl to HCO3>NO3> SO4>Cl. The mean change in water nitrate concentration in areas with tree stands damaged by the bark beetle was smaller (6.17 mg/L; 1.60% mval/L) than that for areas deforested by wind. The concentration of NO3 – in stream water in deforested areas varied more than that in stream water in non−deforested areas.
