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.

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:
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:
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.

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 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:
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.

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:
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.

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:
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.
