With the rapid development of city, many large and medium-sized cities sprawl in urban space,triggering a series of socio-economic issues related to land-use. Based on RS and GIS, selected Kunming as study area for its typical representation of Yunnan plateau mountain cities, used the method of spatial quadrant orientation analysis, obtained the number and structure of construction land expansion in specific direction of study area in period of two different years, and calculated the intensity index and fractal dimensions of the urban expansion. Finally, according to local conditions, spatial expansion variations features of Kunming were analyzed systematically.

The urban fringe, as a part of an urban spatial form, plays a considerably major role in urban expansion and shrinking. After decades of rapid development, Chinese cities have advanced from a simple expansion stage to an expansion–shrinking-coexistence stage. In urban shrinking and expansion, the urban fringe shows different characteristics and requirements for specific aspects such as urban planning, land use, urban landscape, ecological protection, and architectural form, thereby forming expanding and shrinking urban fringes. A comprehensive study of expanding and shrinking urban fringes and their patterns is theoretically significant for urban planning, land use, planning management, and ecological civilisation construction.

This review paper compiles research related to debris flows and hyperconcentrated flows in the central Andes (30°–33° S), updating the knowledge of these phenomena in this semiarid region. Continuous records of these phenomena are lacking through the Andean region; intense precipitations, sudden snowmelt, increased temperatures on high relief mountain areas, and permafrost degradation are related to violent flow discharges. Documented catastrophic consequences related to these geoclimatic events highlight the need to improve their understanding in order to prepare the Andean communities for this latent danger. An amplified impact is expected not only due to environmental changes potentially linked to climate change but also due to rising exposure linked to urban expansion toward more susceptible or unstable areas. This review highlights as well the need for the implementation of preventive measures to reduce the negative impacts and vulnerability of the Andean communities in the global warming context.

The article is devoted to the analysis of the Ukrainian market for the spread of cloud technologies, an overview of growth dynamics, application segments and identifies leading companies that offer services using cloud computing. According to the unanimous forecasts of the world’s leading consulting companies, the rapid improvement and spread of cloud computing is now one of the key trends that in the next 5-8 years will significantly affect the global development of not only the IT industry but also business, finance, public administration, medicine, education and many other areas of human life. Prospects for the rapid development of cloud services in Ukraine encourage more careful consideration of the experience of their application in more «mature» markets and identify the main benefits and risks of these technologies in local conditions. People perceive the cloud as a platform only for storage and computing. However, there are many other opportunities that cloud technologies offer with cloud computing. Currently, cloud computing technologies are becoming increasingly popular. The advantages of this technology are obvious: economy, speed, elasticity, versatility of access. In the future, their use will create a powerful information and telecommunications system, which will be a technological solution for the construction and development of new infrastructure in the country. The world’s largest IT vendors (Microsoft, Amazon, Google and others) somehow implement cloud computing services, providing a wide range of opportunities for users. Thus, cloud computing is software and hardware that is available to the user via the Internet (or local network) in the form of a service that allows you to use a user-friendly web interface for remote access to dedicated resources (computing resources, programs and data). Thus, cloud computing is the next stage of information development of mankind.

<p>The rapid development of Balikpapan City has an impact on the increasingly high demand for land for urban expansion needs. The expansion of Balikpapan City is more directed towards coastal areas which are dominated by mangrove forests. This study discusses the destruction of the mangrove forest and its causal factors and how conservation efforts are being carried out to maintain sustainability. Mangrove forest damage data obtained through surveys and image analysis using NDVI. While the factors causing the damage to mangrove forests were obtained from observations and interviews with the mangrove center manager of Balikpapan. The results showed that there were many mangrove forests that had rare or already damaged that were spread in the West Balikpapan, North Balikpapan, and East Balikpapan Sub-district. This damage is caused by natural and non-natural factors. Natural factors that cause damage to mangrove forests are pests and sedimentation. The non-natural factors are due to the pollution and the opening of fish ponds. Preservation efforts are carried out by replanting mangroves which are only carried out by the mangrove center and some CSR and environmentalists and do not involve the community at large. These Conditions make the mangrove forest in Balikpapan City threatened its sustainability.</p>

With the advent of the Internet Age, the rapid development of modern rural construction and urban-rural integration, the revival of traditional culture and environmental improvement and many other factors, the multi-semantic social relationship of the beautiful countryside has been formed gradually based on the space, culture and locality. The reconstruction and reshaping of beautiful countryside in the Mobile Internet Age takes Yuan Ye as a theory and path to improve the quality of Internet rural culture, and combines the current technological innovation to expound such design ideas as poetic charm, adaptation to local conditions and so on in garden culture, injecting new design vitality to the inheritance of cultural resources and construction of modern rural society.

ResumoEste artigo analisa o processo de expansão urbana recente em Altamira – PA, de modo a verificar as novas tendências de crescimento a partir da instalação da usina hidrelétrica de Belo Monte. São utilizados como bases teóricas os conceitos ligados à morfologia urbana e à produção social do espaço urbano. A expansão urbana recente se constitui a partir de fatores articulados ao processo de instalação da usina hidrelétrica, onde se verifica um crescimento acelerado da malha urbana em várias direções, respeitando o sentido das vias estruturantes. Tal crescimento chega a ultrapassar 50% e se dá a partir de novas instalações urbanas para habitação e uso coletivo, públicas e privadas, que alteram o desenho da cidade, sua paisagem e estrutura urbana. Nesse novo cenário, cabe destaque ao papel dos agentes imobiliários e do poder público, bem como da empresa Norte Energia S.A como indutora de processos e agente ordenador do território.Palavras Chave: Expansão urbana, morfologia, Altamira, Belo Monte.  AbstractThis article analyzes the process of recent urban expansion in Altamira, Pará State, in order to check for new growth trends after the implementation of the hydroelectric plant of Belo Monte. The concepts related to urban morphology and social production of urban space are used as theoretical basis to this study. The recent urban expansion is composed by factors related to the hydroelectric plant implementation process, which shows a rapid growth of the urban mesh in several directions, respecting the way of structuring roads. Such growth exceeds 50% and it happens by means of public and private new urban facilities for housing and collective use that alter the design of the city, its landscape and urban infrastructure. In this new scenario, it is highlighted the real estate agents’, government’s, and  Norte Energia corporation’s roles, being the former one considered an originator territory agent and responsible for  inducing this processes.Keywords: urban expansion, morphology, Altamira, Belo Monte.  ResumenEn este artículo se analiza el proceso de reciente expansión urbana en Altamira-PA, con el fin de comprobar si hay nuevas tendencias de crecimiento después de la instalación de la central hidroeléctrica de Belo Monte.

Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The Urban-Water Harmony (UWH) model is based on the concept of harmony and offers a more integrated approach to urban water management. This model calculates four dimensions, namely urban development, urban water services, water–society coordination, and water environment coordination. And the Analytic Hierarchy Process has been used to determine the indices weights. We applied the UWH model to Beijing, China for an 11-year assessment. Our findings show that, despite the severe stress inherent in rapid development and water shortage, the urban water relationship of Beijing is generally evolving in a positive way. The social–economic factors such as the water recycling technologies contribute a lot to this change. The UWH evaluation can provide a reasonable analysis approach to combine various urban and water indices to produce an integrated and comparable evaluation index. This, in turn, enables more effective water management in decision-making processes.

Hope is much discussed as a future-oriented affect emerging from uncertain living conditions. While this conceptualisation illuminates the role that hope plays in shaping life trajectories, hope itself remains largely unaddressed. In this paper, we approach hope ethnographically as practice through the lens of material-semiotics. We draw on fieldwork in Ouagadougou, Burkina Faso, where hoping turns out to be co-constitutive of peri-urban life and landscape. We challenge person-centred understandings of hope in order to bring materiality back in two ways: first, hoping in its various modes and forms is always situated in particular settings, thus, its enactment has to be reflected; and second, hoping “takes place”, it is co-constitutive of the transformation of urban life. Additionally, we consider the temporality of hoping and highlight how hoping persists through urban space. We conclude that a more profound and thoroughly materialised understanding of hoping’s generative and stabilising potential may strengthen the role of anthropology in current research on socio-ecological transformations.
