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:
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:
Forests perform essential ecological functions - water protection, sanitation, health, recreation, and aesthetics. 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:
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:
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.

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:
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.

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:
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.

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 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.
