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:
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:
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:
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:
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:
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:
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:
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 phenomenon of climate change is addressed through two main strategies: mitigation and adaptation. It is broadly recognized that both strategies are interrelated, yet in the land use sector this connection is particularly strong. In fact, the mentioned sector is one of the most promising areas to combine mitigation and adaptation into a single intervention. In spite of its potential, in practice mitigation and adaptation are still treated as two different policy instruments. Concerns about efficiency have emerged as a result of such a dichotomy. However, how to manage an integrated implementation of mitigation and adaptation is still poorly understood. In this research paper, enabling conditions for an enhanced policy outcome in the land use sector were studied. Specifically, a dynamic optimization problem based on the concept of forest transition – the process of changes in forest cover over time as a country or region develops in social and economic terms – was suggested and solved. Forest transition was used to define initial value problems. After that, steady states were characterized for an unregulated economy and different policy configurations. The results show that partial policy interventions (only adaptation or only mitigation) improved the unregulated economy situation but delivered sub-optimal land allocation. It is only under an integrated implementation that optimality can be restored.

Opis:
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.
