Basic Sanitation

The Amazon boasts a great environmental heritage and abundance of water resources, it is in this remarkable biome where the worst rates of access to basic sanitation services and public health indicators are. This research aims to use the SWOT analysis to generate knowledge capable of subsidizing the public manager in the elaboration of strategic planning to implement sanitary sewage according to the National Policy for Basic Sanitation in a municipality of the Brazilian Amazon under development and urban expansion. The practices adopted for this task relate to the concepts of the SWOT matrix, public policies for basic sanitation with a focus on sanitation, urban sprawl and social impacts on human health related to poor sanitation. Identifying in the municipal legal norms the strategic planning to order the development and the urban expansion and the practices foreseen to meet the National Policy for the Basic Sanitation and implantation of the sanitary sewage in the studied municipality. This is a descriptive exploratory research based on document and field research according to legal and environmental norms with qualitative and quantitative results. Despite the result demonstrating that the strategic planning for the implementation of sewage in urban expansion projects results in sustainable urban development, the municipality under study did not meet the legal and environmental standards for the implementation of sewage in new subdivisions causing environmental, social and economic problems.

This paper focuses on the suitability of urban expansion in mountain areas against the background of accelerated urban development. Urbanization is accompanied by conflict and intense transformations of various landscapes, and is accompanied by social, economic, and ecological impacts. Evaluating the suitability of urban expansion (UE) and determining an appropriate scale is vital to solving urban environmental issues and realizing sustainable urban development. In mountain areas, the natural and social environments are different from those in the plains; the former is characterized by fragile ecology and proneness to geological disasters. Therefore, when evaluating the expansion of a mountain city, more factors need to be considered. Moreover, we need to follow the principle of harmony between nature and society according to the characteristics of mountain cities. Thus, when we evaluate the expansion of a mountain city, the key procedure is to establish a scientific evaluation system and explore the relationship between each evaluation factor and the urban expansion process. Taking Leshan (LS), China—a typical mountain city in the upper Yangtze River which has undergone rapid growth—as a case study, the logic minimum cumulative resistance (LMCR) model was applied to evaluate the suitability of UE and to simulate its direction and scale. The results revealed that: An evaluation system of resistance factors (ESRFs) was established according to the principle of natural and social harmony; the logic resistance surface (LRS) scientifically integrated multiple resistance factors based on the ESRF and a logic regression analysis. LRS objectively and effectively reflected the contribution and impact of each resistance factor to urban expansion. We found that landscape, geological hazards and GDP have had a great impact on urban expansion in LS. The expansion space of the mountain city is limited; the area of suitable expansion is only 23.5%, while the area which is unsuitable for expansion is 39.3%. In addition, it was found that setting up ecological barriers is an effective way to control unreasonable urban expansion in mountain cities. There is an obvious scale (grid size) effect in the evaluation of urban expansion in mountain cities; an evaluation of the suitable scale yielded the result of 90 m × 90 m. On this scale, taking the central district as the center, the urban expansion process will extend to the neighboring towns of Mianzhu, Suji, Juzi and Mouzi. Urban expansion should be controlled in terms of scale, especially in mountain cities. The most suitable urban size of LS is 132 km2.This would allow for high connectivity of urban-rural areas with the occupation of relatively few green spaces.

Research Facilities

The urban expansion currently under development around the two materials science facilities MAX IV and European Spallation Source in Lund, Sweden, surrounds two meticulously designed research facilities steered by global demands. The new urban area, together with the research facilities dedicated to science and the development of knowledge, expands the city of Lund onto high-quality agricultural land. In doing so, the municipal planning is attempting to align contemporary ideas of sustainable urban development with large-scale scientific infrastructure. This actualizes an ethical dilemma as the urban expansion onto productive agricultural land overrides previous decisions taken by the municipality regarding land use. It can also be understood as going against national land use policy which states that development on productive agricultural land should be avoided. As the planning stands today, the research facilities heavily push local urban development into the area while the intended research outcomes primarily relate to a global research community tied to international scientific demands for materials science. Although the Brunnshög area is realized through a neutralizing planning strategy, thought to balance and compensate for the development on farmland, the effects of the counterbalancing acts are primarily played out at a local urban level in terms of diverse, exciting, and locally sustainable neighbourhoods. The land use protection policies meant to secure national food production rather operates on a national scale. The argument made in this text is that sustainable development, and the intended balancing acts it involves, ought to be carefully considered in terms of scalar effects. Sustainable planning<em> </em>effects’ <em>scalar extent</em> should be taken into account through careful assessment of the step between good intentions and expected outcomes.

Urban Sprawl is a disturbing issue to geographers, urban planners and allied professionals in the 21st century.  The anxiety is based mainly on the social, political, economic, cultural and environmental consequences of rapid urban growth.  Hence, this study examines the reasons for urbanization, as well as encroachment of urban development into the border belt.  Next, the study probes into the causes, consequences and adverse effects of uncontrolled infringement and conversion of rural land to urban uses.  Likewise, the study investigates the processes of land use development, population expansion and physical growth, as well as their ecological foot prints.  Consequently, the study identified the major causes of urban sprawl as rapid population increase, high level of urban development pressure, provision of housing, changes in living standard, as well as technological changes among others.  Also, the study found out that urban sprawl is desirable because of the benefits of spread of development, low rent at the periphery, as well as lesser pressure on the environment of the border belt.  Also, the effects of urban sprawl were recognized as destruction of the means of livelihood of the rural dwellers at the urban fringe belt, land fragmentation, food scarcity, changes in the ecosystem, environmental pollution, biodiversity loss, as well as loss of wildlife habitat.  For the achievement of sustainable urban development in the 21st century and beyond, the study recommends environmental monitoring with the aid of geographic information systems and remote sensing techniques, environmental impact assessment, development control, farm land policy, regulation of land allocation, sustainable land use management, as well as enforcement of planning policies.

Cities, the core of the global climate change and economic development, are high impact land cover land use change (LCLUC) hotspots. Comprehensive records of land cover land use dynamics in urban regions are essential for strategic climate change adaption and mitigation and sustainable urban development. This study aims to develop a Google Earth Engine (GEE) application for high-resolution (15-m) urban LCLUC mapping with a novel classification scheme using pan-sharpened Landsat images. With this approach, we quantified the annual LCLUC in Changchun, China, from 2000 to 2019, and detected the abrupt changes (turning points of LCLUC). Ancillary data on social-economic status were used to provide insights on potential drivers of LCLUC by examining their correlation with change rate. We also examined the impacts of LCLUC on environment, specifically air pollution. Using this approach, we can classify annual LCLUC in Changchun with high accuracy (all above 0.91). The change detection based on the high-resolution wall-to-wall maps show intensive urban expansion with the compromise of cropland from 2000 to 2019. We also found the growth of green space in urban regions as the result of green space development and management in recent years. The changing rate of different land types were the largest in the early years of the observation period. Turning points of land types were primarily observed in 2009 and 2010. Further analysis showed that economic and industry development and population migration collectively drove the urban expansion in Changchun. Increasing built-up areas could slow wind velocity and air exchange, and ultimately led to the accumulation of PM2.5. Our implement of pan-sharpened Landsat images facilitates the wall-to-wall mapping of temporal land dynamics at high spatial resolution. The primary use of GEE for mapping urban land makes it replicable and transferable by other users. This approach is a first crucial step towards understanding the drivers of change and supporting better decision-making for sustainable urban development and climate change mitigation.

Lake Change

With the development of urbanisation, the contradiction between urban expansion and lake protection becomes increasingly evident. Particularly, lake reclamation of urban construction causes serious damage to the water system and further affects the ecological environment of urban areas. On the basis of the interpretation and analysis of long time-series remote sensing images, this study evaluated the spatial pattern and dynamic changes of urban built-up areas and lakes in Wuhan from 1987–2018 and analysed the role of urban policies in this process. A coupling coordination degree model was used to analyse the correlation between them. Results show that with the continuous advancement of urban construction and renewal of urban policies, the coupling degree between urban expansion and lake change in Wuhan has been on the rise in the past 30 years. Moreover, the antagonistic relationship between urban construction and lake protection has gradually eased from severe imbalance to slightly balanced, and the negative impact of urban development on lake change has gradually decreased. The findings underscore the need for Wuhan to adhere to policies that promote lake protection. Lake supervision should be strengthened, and ecological restoration should be actively promoted. Furthermore, sustainable urban development policies should be maintained to improve the quality of urban development.

Understanding the spatiotemporal characteristics of urban expansion is increasingly important for assisting the decision making related to sustainable urban development. By integrating remote sensing (RS), spatial metrics, and the cellular automata (CA) model, this study explored the spatiotemporal dynamics of urban expansion and simulated future scenarios for Hangzhou City, China. The land cover maps (2002, 2008, and 2013) were derived from Landsat images. Moreover, the spatial metrics were applied to characterize the spatial pattern of urban land. The CA model was developed to simulate three scenarios (Business-As-Usual (BAU), Environmental Protection (EP), and Coordination Development (CD)) based on the various strategies. In addition, the scenarios were further evaluated and compared. The results indicated that Hangzhou City has experienced significant urban expansion, and the urban area has increased by 698.59 km2. Meanwhile, the spatial pattern of urban land has become more fragmented and complex. Hangzhou City will face unprecedented pressure on land use efficiency and coordination development if this historical trend continues. The CD scenario was regarded as the optimized scenario for achieving sustainable development. The findings revealed the spatiotemporal characteristics of urban expansion and provide a support for future urban development.

Urban waterfronts have inevitable linkage with sustainable urban living. To ensure sustainable urban development, waterfronts of the cities must be considered carefully while planning for an urban area. This study aimed at finding out the existing problems of waterfront areas of Bhairab River in Khulna city and thereby proposes some effective recommendations to improve the condition of the waterfront areas. Moreover, this study aims at pointing out the importance of waterfronts in urban perspective and how they influence urban development in aesthetic and economic issues. Performing questionnaire survey this study collected data on social, economic and environmental factors of influencing or representing the waterfront area (e.g. economic condition, income, savings, housing condition, education level, encroachment, waterlogging). Results of SWOT analysis showed the major strengths, weakness, opportunity and threats of the area. The major strength is the income generated from industries and the weakness is the excessive disposal of industrial wastes. The approved Detailed Area Plan (DAP) 2018 of Khulna Development Authority (KDA) has proposed a well decorated railway and tourist information center. Both quantitative and qualitative analyses were carried out to develop a conception about the study area and socio-economic condition of its local people. The study found that waterfront areas in Khulna city face a number of problems (e.g. pollution, waterlogging, encroachment, inadequate recreational facilities). Considering existing condition this study provided some policy recommendation subdividing the study area into five zones to organize existing land use following proper planning standards. Consequently, waterfronts in Khulna city will be attractive places for people and that will contribute to the sustainable development of the city.

The City

Rapidly changing framework conditions for city development such as globalization, demographic trends, deindustrialization, technological developments or the increasing urbanization as well as the economic, social and political changes are profound and change our urban life. This leads, that the cities of tomorrow will differ essentially from today´s city principles. Therefore innovative, strategically wise and quick action becomes a criterion for success. Here, more than ever, local conditions and requirements must be taken into account as well as global framework conditions. The responsible parties have to set the course so that the “City” remains competitive and sustainable in the future. Therefore, innovation processes and sustainable strategies for dealing with the diverse and complex agendas of a city in dialogue with those who are responsible for it must be initiated and management systems established so that new things can develop continuously and systematically. This work illustrates how the boundaries created to manage and market future liveable and sustainable city destinations are the root of the practical and academic problems that trouble city management these days.  This paper aims to develop the new integrated Smart Urban Profiling and Management model, which presents a new integrated approach for city marketing as an instrument of sustainable urban development. In this way, comprehensive research was conducted to evaluate if the holistic city marketing concept that integrates elements of smart city strategies and adaptive management is a more suitable instrument and integrative process than conventional city marketing in order to improve the sustainable urban development. Therefore, in this work, the designed “Smart Urban Profiling and Management model” for city management introduces an alternative and holistic perspective that allows transcending past boundaries and thus getting closer to the real complexities of managing city development in dynamic systems. The results offer the opportunity to recognize the city and consequently allow to developing successful strategies and implementation measures. This study targets to contribute to this endeavor in order to produce new impulses and incitements in the city management field and shall provide a fresh impetus for a new understanding of city marketing as the initiator of development processes, mobilization and moderator in concerning communication and participation processes. This paper is written from a perspective addressing those responsible for the city- management, city- & urban marketing and development.
