Abstract In south west Ethiopia, the numbers of immigrants from other parts of the country have been large over the last few years. This huge migration is considered to be a fundamental factor in the degradation of the natural forest because of the livelihood strategy difference of non-migrants and migrants. Thus, we investigated the link between internal migration, rural livelihood strategies and sustainable forest management in the study area. The study investigated the effect of internal migration and peoples’ livelihood strategy choice on sustainable forest management systems. The research was based on both primary and secondary data. The primary data was collected from 392 household questionnaires. The descriptive analysis was supported with an empirical analysis using a multinomial logistic regression model. Internal migration is high because of push and pulls factors related to the migrant people. In addition, there is a livelihood choice difference between migrants and non-migrants. Migrants choose farm activities rather than a forest based livelihood means relative to non-migrants. These high population pressure and livelihood choice differences coupled with weak institutional frameworks have created a burden on the natural forest. Thus, informed policy options regarding internal migration, livelihood strategies and sustainable forest management would be a useful approach to reducing the burden on the natural forest.

Abstract Though urbanization promotes development, the gender gap is being perceived in many socio-economic aspects, in the Indian urban economic scenario. With a 31.16% urban population (in 2011), India has experienced a lopsided development of its urban hierarchy in favour of metropolitan growth which accommodates 42.31% of the total urban population. For various socioeconomic reasons it has a declining female economic participation rate. Sehore M.C. (Madhya Pradesh), an upcoming Class I city, located near the metropolitan cities of Bhopal and Indore, is showing perceptible changes in female work participation, indicating a potential for development in Sehore M.C. along with other smaller cities in Madhya Pradesh. Based on the methodology for the Global Gender Gap Index (GGGI, WEF 2018), the ward wise figures for Sehore M.C. for the partly adopted subindices of Survival, Social, and Economic Participation were calculated using local area indicators from standard international and national agencies to bring out the inter-ward variations in gender gap for Sehore M.C.. Spatial mapping of GGI showed that approximately 91% of wards belonged to the high category but 9% of wards were from the medium category. Suggestions for the promotion of gender parity in the city are made for the overall empowerment of females in Sehore M.C. within the constraints of an urban economic scenario.

Abstract Lagos State, which is home to Lagos metropolis and the eighteenth largest urban agglomeration in 2018 in the world, has been characterized by rapid urbanization. An earlier study of the eastern segment of the state revealed dramatic urban growth in previously rural local councils where it replaced mostly ecological assets. For a statewide view of the landscape pattern changes, this study examined the western segment of the state to characterize the magnitude and trend of these changes. This was done with Landsat images for 1984, 2006 and 2015 along with ENVI 5.0 software and FRAGSTATS v.4.2 spatial pattern analysis program. Results show that cumulatively, the ecological assets, which comprised 75% of the area in 1984, have been whittled down to about 34% by 2015 having been lost through urban development. At the council level in 2015, the highest growth areas, in decreasing order of magnitude, were Alimosho, Badagry, Ojo and Amuwo Odofin local government areas. Both class and landscape-level metrics confirmed the dominance and fragmentation of the resultant landscape in 2015 by urban development. In 1984, vegetation dominated the landscape at 55% coverage and was the largest feature with the highest area-weighted contiguity or connectedness index. Thirty-one years later in 2015, built-up areas were the dominant patch with 54% coverage and the highest contiguity and area-weighted contiguity index, higher than vegetation. These findings have narrowed the information gap about the spatial and temporal changes in the ecological assets of the western segment of Lagos State as a result of rapid urban expansion.

Abstract The paper presents changes in the landscape of inland dunes in one of the basins in the eastern part of Silesian Upland. Based on the analysis of archival maps and historical sources, the former dune landscape of Dąbrowa Basin was reconstructed. The current state of its preservation was determined based on contemporary cartographic materials and field research. It was established that the dunes occur on the floodplain, under-slope flattening, and cuesta escarpment (Ząbkowice Hummock)). The source of aeolian sands was fluvioglacial and alluvial deposits, which, as a result of aeolian transport, were moved to higher and higher morphological levels and stabilized on a substrate of different lithology and age. The impermeability of the bedrock – tills, clays, mudstones, siltstones had a significant influence on the dune landscape. It resulted in the presence of wetlands and peat bogs in the vicinity of most dunes. Consequently, the landscape of the valley was distinguished by a lot of contrast in terms of vegetation - dry pine forests or grassy areas on the dunes and moisture-loving vegetation in their surroundings. However, this landscape was under strong human pressure. Most of the dunes (3/4) have been destroyed in the last hundred years due to sand mining and industrial and residential construction. One of the largest dune fields in the Przemsza River basin and most floodplain and under-slope flattening dunes were utterly destroyed. In addition, an interesting dune at Triassic clays was almost fully exploited, and a rare case on the Silesian Upland where a dune entered the Triassic limestones was partially covered with concrete. There are only 25 dunes in the study area - they deserve protection both as the last fragments of the inland dunes landscape in this part of the Silesian Upland and for historical and natural reasons.

Abstract Acquisition of large-scale agricultural land for urbanization and industrialization is a widespread phenomenon in Vietnam. This acquisition has impacted those households whose land was expropriated in many ways, such as economic, cultural, and social aspects. In this research, the author surveyed 100 households who lost their land for Da Nang Hi-Tech Park project to collect data about the change in their livelihoods and the satisfaction level with their quality of life. This study aimed to answer three questions relating to employment, compensation expenses, and life. The results show that these householders still have many difficulties adapting to a new life after nearly ten years. The unemployment rate increases, but it depends on the gender and age of the worker. Compared with the five years ago, the households’ incomes also decreased by 190 USD/household. The misuse of compensation money paid for their has also had negative impacts on their livelihoods. Some other problems such as environmental pollution and social evils have put pressure on households who lost their land. Hence, most of these households want to return to their previous agricultural life.

Abstract Recurrent wildfires in Ukraine exert severe impacts on the environment, human health and security as well as damage to private and public assets. From 2007 to 2020, the frequency of large wildfires has increased and reached a level that has not occurred previously. The period during April-October 2020 was the worst in modern Ukrainian history for the occurrence of catastrophic fires, e.g. in the Chernobyl Exclusion Zone (67 000 ha), Zhytomyr oblast (43 000 ha), Lugansk oblast (35 000 ha) and Kharkiv oblast (8 000 ha). In Ukraine there is the additional problem of open burning, mainly burning agriculture residues, which covers two million hectares (ha) annually. State forestry enterprises who are responsible for the management of 71% of the Ukrainian forests (7.6 million ha)and agricultural holdings are also responsible for the management of 41.3 million ha of croplands. The remaining forest users manage forest areas of 3.1 million ha within reserves and national nature parks. This article presents a brief overview of the problem of forest fires as well as of fires in other landscapes in Ukraine, and includes a critical reviews of the current wildfire management system and a description of the main features of the national wildfire management strategy. It also highlights the results of a survey of numerous stakeholders conducted on landscape fires in Ukraine. Based on the review of global and regional experiences, as well as existing fire risks in Ukraine, recommendations were developed for implementing an integrated landscape level national fire management approach.

Abstract The aim of the study was to diagnose the current and projected pace of ageing in the societies of European post-communist countries from the point of view of its being an increasing economic burden on the economically active population. The analysis covered the years 1990–2050. Ageing is already visible and, according to the forecast, the process will accelerate even more. The old-age dependency ratio (OADR) is expected to exceed 50 in half of the countries in the study by 2050. This will result in major threats to the further development of these countries and will lead to poverty and social exclusion of the elderly. In order to slow down the ageing process, the authorities of these countries should take a number of actions, the most important of which are the implementation of an effective and efficient pro-natal policy (so that the total fertility rate would increase above 2.1), and a well-thought-out migration policy.

Abstract CO2 emissions are one of the main causes of the global problem of climate change, the solution to which requires the efforts of every country. One of the main polluters is the energy sector, which includes transport. Despite the seemingly small share of aviation in emissions, its role as a polluter and CO2 emitter cannot be underestimated due to calculated specific rate and a number of factors that were researched. The purpose of this study was to analyze the aviation share in the polluters’ structure and to study if Covid-19 restrictions influence on it, to investigate the share of CO2 emissions from air transport in Ukraine and to assess its impact, to forecast CO2 emissions in Ukraine by 2030 and to build scenarios of possible changes in the direction of decarbonization in the aviation industry. Analysis and synthesis, comparison, methods of pairwise regression and modelling scenarios were used for solving these tasks. The results show that the aviation industry could achieve the carbon reduction targets only by applying different types of carbon pricing with conducting the research and development in the sphere. The last significant improvement in aircraft design technologies and flight operations was achieved almost 60 years ago. Economic incentives at the international and local scales should be used to stimulate aviation manufacturers to invest significant money on R&D to find stable solutions to achieve decarbonization. Development of Ukrainian aviation industry should not stand aside from global trends and must meet modern challenges, including environmental issues. The created scenarios show solutions to achieve decarbonization goals that align with EU best practices.

Abstract Hingol National Park (HNP), in Baluchistan, Pakistan, is rich in biodiversity and has a variety of eco-services and marine eco-services. It has dune and mountain habitats that provide a significant environment for wildlife, including amphibians, dolphins, green marine turtles, and migratory birds, but the number of species is declining. HNP faces many problems such as unregulated tourism and lack of a budget to protect and conserve precious wildlife. The study used a negative binomial regression model and a zero-truncated regression model to estimate the visitors’ travel demand and recreational value of the National Park by collecting a sample of 210 respondents.. The study estimated a consumer surplus of USD 270 per person per visit and thus a total annual recreational value of the park at USD 35.11 million. Since the elasticity of demand is low, the study suggests the imposition of an entrance fee of USD 0.86 (PKR 100) that would generate an annual revenue of USD 113,000. It is recommended that both provisional and federal governments should take the necessary steps to maintain and promote heritage tourism in the region by reshaping the national parks for the protection of scarce natural resources and the protection of biodiversity.

The study estimated a consumer surplus of USD 270 per person per visit and thus a total annual recreational value of the park at USD 35.11 million. Since the elasticity of demand is low, the study suggests the imposition of an entrance fee of USD 0.86 (PKR 100) that would generate an annual revenue of USD 113,000. It is recommended that both provisional and federal governments should take the necessary steps to maintain and promote heritage tourism in the region by reshaping the national parks for the protection of scarce natural resources and the protection of biodiversity.","PeriodicalId":54005,"journal":{"name":"Environmental & Socio-Economic Studies","volume":"9 1","pages":"52 - 62"},"PeriodicalIF":1.1,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48867091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Several urban centres of different sizes have developed over time, and continue to grow, within the basin of Lake Victoria. Uncontrolled urban development, especially along the lake shore, puts environmental pressure on Lake Victoria and its local ecosystem. This study sought to monitor the extent and impacts of urban development (as measured by population growth and built-up land use/land cover) in the Lake Victoria basin, Kenya, between 1978 and 2018. Remote sensing and GIS-based land use/land cover classification was conducted to extract change in built-up areas from Landsat 3, 4, 5 and 8 satellite imagery obtained for the month of January at intervals of ten years. Change in population distribution and density was analysed based on decadal census data from the Kenya National Bureau of Statistics between 1979 and 2019. A statistical regression model was then estimated to relate population growth to built-up area expansion. Results indicate that the basin’s built-up area has expanded by 97% between 1978 and 2018 while the population increased by 140% between 1979 and 2019. Urban development was attributed to the rapidly increasing population in the area as seen in a positive statistical correlation (R2=0.5744) between increase in built-up area and population growth. The resulting environmental pressure on the local ecosystem has been documented mainly in terms of degradation of lake water quality, eutrophication and aquatic biodiversity loss. The study recommends the enactment and implementation of appropriate eco-sensitive local legislation and policies for sustainable urban and rural land use planning in the area. This should aim to control and regulate urban expansion especially in the immediate shoreline areas of the lake and associated riparian zones.
