Urbanization in Southwest China, an extensive mountainous region, has been unprecedentedly rapid in the past two decades, particularly with the implementation of “Great West Development”. However, most present studies on urbanization of Chinese cities are limited to coastal area. Little is known about the urbanization pattern and underlying mechanism in this region. The main purpose of this research is to analyze the process of rapid urbanization and its impact on mountain environment, using Chongqing, the well known “mountain city” in China, as an example. Four time-series satellite images were employed to extract the landscape data. The result was assessed by several “landscape metrics”. The research also investigated how complex natural factors as well as socio-economic factors exerted influence on the urbanization. Based on examination of present landscape, a planning model which was believed suitable for mountain urban development was proposed.

This study integrated multi-temporal Landsat images, the Markov-Cellular Automation (CA) model, and socioeconomic factors to analyze the historical and future farmland loss in the Delhi metropolitan area, one of the most rapidly urbanized areas in the world. Accordingly, the major objectives of this study were: (1) to classify the land use and land cover (LULC) map using multi-temporal Landsat images from 1994 to 2014; (2) to develop and calibrate the Markov-CA model based on the Markov transition probabilities of LULC classes, the CA diffusion factor, and other ancillary factors; and (3) to analyze and compare the past loss of farmland and predict the future loss of farmland in relation to rapid urban expansion from the year 1995 to 2030. The predicted results indicated the high accuracy of the Markov-CA model, with an overall accuracy of 0.75 and Kappa value of 0.59. The predicted results showed that urban expansion is likely to continue to the year of 2030, though the rate of increase will slow down from the year 2020. The area of farmland has decreased and will continue to decrease at a relatively stable rate. The Markov-CA model provided a better understanding of the past, current, and future trends of LULC change, with farmland loss being a typical change in this region. The predicted result will help planners to develop suitable government policies to guide sustainable urban development in Delhi, India.

As most of the forest fires in South Korea are related to human activity, socio-economic factors are critical in estimating their probability. To estimate and analyze how human activity is influencing forest fire probability, this study considered not only environmental factors such as precipitation, elevation, topographic wetness index, and forest type, but also socio-economic factors such as population density and distance from urban area. The machine learning Maximum Entropy (Maxent) and Random Forest models were used to predict and analyze the spatial distribution of forest fire probability in South Korea. The model performance was evaluated using the receiver operating characteristic (ROC) curve method, and models’ outputs were compared based on the area under the ROC curve (AUC). In addition, a multi-temporal analysis was conducted to determine the relationships between forest fire probability and socio-economic or environmental changes from the 1980s to the 2000s. The analysis revealed that the spatial distribution was concentrated in or around cities, and the probability had a strong correlation with variables related to human activity and accessibility over the decades. The AUC values for validation were higher in the Random Forest result compared to the Maxent result throughout the decades. Our findings can be useful for developing preventive measures for forest fire risk reduction considering socio-economic development and environmental conditions.

<p>A hipótese desta pesquisa surge através da premissa de que a maioria das áreas verdes localizadas em municípios brasileiros acabam sendo alteradas negativamente pelo processo de expansão urbana e pelo aumento populacional. O objetivo da pesquisa é realizar uma análise multitemporal da expansão urbana relacionada com o aumento populacional de Maringá-PR que influenciaram na mudança da paisagem das áreas verdes do município, caracterizando por meio de períodos estabelecidos em décadas como foi sendo materializada a expansão da malha urbana em direção as áreas verdes. Concluiu-se que a urbanização acelerada do município começou a envolver as áreas verdes da cidade em todas as direções e os primeiros processos de degradação ambiental começaram a surgir, restando pequenas manchas de mata nativa. Verificou-se que os principais problemas ambientais do Parque Municipal do Cinquentenário coincidem com a aproximação da urbanização no entorno deles, em suas áreas limítrofes. Concluiu-se também, que a metodologia aplicada da análise multitemporal, mostrou-se eficiente quanto às avaliações temporais urbanas e ambientais, tornando-se ferramenta útil para um futuro plano de gestão ambiental dos órgãos governamentais responsáveis.</p><p><strong>Palavras-Chave:</strong> Análise multitemporal, expansão urbana, aumento populacional, degradação ambiental, áreas verdes.</p><p><strong>Abstract </strong></p><p>The hypothesis of this research comes from the premise that the majority of green areas located in municipalities end up being changed negatively by the process of urban expansion and population increase. The objective of the research is to conduct a multi-temporal analysis of urban expansion related to the population increase of Maringa-PR that influenced the landscape change from green areas of the city, featuring through periods established for decades as it was being materialized the expansion of the urban fabric toward the green areas. It was concluded that the rapid urbanization of the city began to engage the green areas of the city in all directions and the first environmental degradation processes began to emerge, leaving small patches of native forest. It was found that the main environmental problems of the Cinquantenaire Park Municipal coincide with the approach of urbanization in their environment, in their neighboring areas. It was also concluded that the methodology applied in the multi-temporal analysis, proved efficient as to urban and environmental temporal ratings, becoming a useful tool for future environmental management plan of the responsible government agencies.</p><p><strong>Keywords:</strong> Multitemporal analysis, urban expansion, population increase, environmental degradation, green áreas.</p>

From hard to soft: theory and Neolithic studies in Scotland

The Past

The Scottish Theoretical Archaeology Group (STAG) conference organisers expressed some doubts about how far theory has changed, and impacted, archaeological establishment and academia in Scotland. In this paper, I will argue that Scotland is certainly not isolated in a theoretical sense, although in the past, Scottish archaeology could be accused of being theoretically conservative, or at least dependent on ideas and models developed elsewhere. A case-study looking at Neolithic studies will be used to illustrate that despite some recent critical historiographies of the study of the period in Scotland, archaeologists in Scotland and those working with Scottish material have been theoretically innovative and in step with wider paradigm changes. The study of the Neolithic in Scotland, it could be argued, has been shaped by theory more than the study of any other period; we are not isolated, but rather part of wider networks of discourse.

Globalisation combined with resources of oil and gas has led to an industrial society in Malaysia.  For the past 30 years, rapid urban growth has shifted from 73% rural to 73% urban population. However, the peak oil crisis and economic issues are threatening the growth of urbanisation and influencing the trends of population mobility. This paper documents the beginnings of a reverse migration (urban-to-rural) in Malaysia.  The method adopted case study that involves questionnaires with the urban migrants to establish the desires, definite intentions and reasons for future migration. Based on this data, it predicts a trend and rate of reverse migration in Malaysia.

Some of the renowned world tourism countries have special peculiarities in character in terms of their nature reserves and built environments; that made them stand out for their attractions and visits. These qualities range from conservation and preservation of nature reserves, built environments- epoch architectural supports over the years; historical heritage; political; religious; socio-economic; cultural; and  high technology that enhance culture. The virtues of multi- ethnic groups and multi- cultural nature gave Nigeria a rich cultural heritage, and she is blessed with natural wonders, unique wildlife, and a very favorable climate. More often than not less attention and importance are placed over the nature reserves and built environments to the detriment of tourism in lieu of other sectors. Summarily the country lacks the culture of conservation and preservation of her abundant resources to promote cultural tourism. Case study strategy was applied in the research tours with reports of personal experiences, documentaries and analyses of sites visited in Europe and Nigeria were highlighted with references to their attributes in terms of structures and features that made up the sites as relate to culture and attraction.The task in keeping rural, city landscapes and nature reserves alive stands out as the secret of communication link from the past to present and the future; which tourism developed nations reap as benefits for tourist attraction.
