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:
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.

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.

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.

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.

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.

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.

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:
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.

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.
