Rural settlements in mountainous regions are a typical process that occurs in many places around the world and have a number of implications on the landscape. Among them is a threat it possesses to the conservation and management of Afromontane ecosystems. This study assessed the socio-economic factors that drive the changes in land use and forest cover and the extent of land use and vegetation cover in and around Magamba Nature Reserve. Focus group discussion, direct field observation and household survey were used to acquire socio-economic information that impacts land use and forest cover. Through the use of Remote Sensing and GIS methods Landsat satellite images of 1995, 2008 and 2015 were employed to identify the extent of the changes in land use and forest cover. The perceived factors for the changes include education level, unemployment, landless/limited, landholding, population pressure, expansion of built-up areas and agricultural land at the expense of other land covers. This study revealed the transformation of natural forest and associated vegetation from one form to another. There was a decrease in natural vegetation from 61.06% in 1995 to 26.02% in 2015 and increase in built-up areas by 6.69% and agricultural areas by 4.70%. This study recommends conservation monitoring and strong law enforcement relating to natural resources so as to promote sustainable use of resources to rescue the diminishing ecosystem services.

AbstractUnderstanding and modeling of land use change is of great significance to environmental protection and land use planning. The cellular automata-Markov chain (CA-Markov) model is a powerful tool to predict the change of land use, and the prediction accuracy is limited by many factors. To explore the impact of land use and socio-economic factors on the prediction of CA-Markov model on county scale, this paper uses the CA-Markov model to simulate the land use of Anren County in 2016, based on the land use of 1996 and 2006. Then, the correlation between the land use, socio-economic data and the prediction accuracy was analyzed. The results show that Shannon’s evenness index and population density having an important impact on the accuracy of model predictions, negatively correlate with kappa coefficient. The research not only provides a reference for correct use of the model but also helps us to understand the driving mechanism of landscape changes.

Poland is not one of the leaders in the use of renewable energy sources (RES), and most energy is still produced using hard coal and lignite. Therefore, there are noteworthy emissions of air pollution (including ashes and greenhouse gases), and the Polish energy sector is characterized by a substantial degree of carbonization, which, as a result, threatens to expressively increase the costs of electricity production, leading to financial penalties imposed by the EU. The aim of this paper is to analyze socio-economic factors influencing the development of the RES sector in Poland. According to this aim, expert research was carried out, in which the factors influencing development potential of RES were assessed at two levels (level II – 5 factors, level III – 15 factors) according to the factor tree analysis. Based on the analysis of the level II factors, it can be concluded that the development of the RES sector in Poland will depend to a decisive extent on factors such as: EU decisions and Polish legislation affecting the development of the RES sector in Poland, prices and availability of conventional energy carriers. Other two factors – regional policy on ecology and ecological awareness in Poland – have so far little impact on the development of this sector in the state. The analysis of the level III factors shows that the greatest impact on the development of the RES sector in Poland is the influence of European lobbying of manufacturers of machinery and equipment for renewable energy production on EU law, the impact of Polish lobbying of conventional energy producers on Polish law in the production of renewable energy and the influence of European lobbying of renewable energy producers into EU law.

Abstract  – The calculation of the value of the Reasonable Land Turnover Terdamapak Job Reaktifasi railway line for arbitration was Muaro Logas was part of the study of the action of liberation/land and buildings for the reform plan of the reaktifasi railway line between Muaro-Logas is part of the planning of the reactivation railway line. This study analyzes regulations and policies, perceived an inventory and survey/census by identifying the affected community land procurement, with regard to the characteristics and the types of harm experienced, agreement agreement between the local government, the province and the Center in funding the acquisition of land; analyze optimum land procurement and analyse livelihood for the population affected by socio-economic factors, analyzing the parameters with the social, cultural, and economic related to population, the impact of the procurement of land and influence implementation of the work against the poor, residents of the tribal minorities, alienated, and other vulnerable groups, including women, as well as the institutional framework in planning the liberation of land and the settlements back including duties and responsibilities each institution. In the calculation of the Reasonable Replacement Value using Standar Penilaian Indonesia306 (SPI 306) about the assessment of the provision of Land for development for the benefit of the public

Background: Violent behaviour in youth is regarded as a significant public health problem associated with severe physical and psychological consequences. Despite the availability of rehabilitation programmes rendered at child and youth care centres (CYCC's) in the Limpopo Province, South Africa, there is an escalation and repetition of violent behaviours among the youth due to some underlying socio-economic factors. Objective: The study sought to explore and describe the factors contributing to violent behaviours among the youth. Methods: A qualitative, explorative, and descriptive research design was used. A non-probability, purposive sampling method was used to select participants in this study. The study population consisted of youth, from the age of 15-20 years old, who were admitted to the child and youth care centres due to violent behaviours. Focus group discussions and in-depth individual interviews were used to collect data from participants. A semi-structured interview guide and focus group discussion guide were used to collect data until data saturation which occurred after interviewing 48 participants. Data were analysed following Tesch’s open code data analysis technique. Measures to ensure trustworthiness and ethical principles were adhered to. Results: Two themes emerged from the analysed data, namely, the socio-economic factors contributing to violent behaviours among the youth in CYCCs and the effectiveness of rehabilitation programmes for violent youth behaviours in CYCCs. Eight sub-themes were derived from the two main themes. The home environment, the influence of delinquent peers, availability, and misuse of drugs and alcohol were most cited as the factors contributing to violent behaviours among the youth in CYCCs in the Limpopo Province. The study's findings revealed that youth had little knowledge of the impact that violent behaviour has on the victim, themselves, their families, and society. Conclusion: Rehabilitation programmes for violent behaviours among the youth will have better outcomes by involving the youth's family, especially the parents/guardians. Also, the child and youth care centres and youth violence policymakers need to emphasise family education as one of the most crucial violence prevention strategies in vulnerable youth.

The number of Internet users around the world has been steadily growing and this growth has provided the impetus and the opportunities for global and regional e-commerce. However, as with the Internet, different characteristics (infrastructure and socio-economic) of the local environment have created a significant level of variation in the acceptance and growth of e-commerce in different regions of the world. Our research focuses on the impact of these infrastructure and socio-economic factors on e-commerce development in China and the findings provide insights into the role of culture in e-commerce, and the factors that may impact a broader acceptance and development of e-commerce in China. In this chapter, we present and discuss our findings, and propose some strategies for success for e-commerce in China.
