Planning Methods

One of major factors of deterioration in a microclimate of urban development in the conditions of the Rostov region, is degradation of landscapes owing to violation of water balance of the territory. In article the main reasons for violation of water balance which included natural features of the region, a consequence of anthropogenic influence, climatic changes, etc. are considered. Examples from the world practice of urban planning, which show the relevance and effectiveness of compensation for the effects of anthropogenic im-pacts and climate change using planning methods, are given. The experience of the United States, the Nether-lands, Canada and other countries that use water-saving technologies in planning is considered. The rela-tionship of urban planning and the formation of sustainable urban landscapes is shown. The integration of water-saving technologies into the urban environment can be a means of optimizing landscapes and a means of creating unique urban spaces. Reclamation of the urban landscape of low-rise buildings is a necessary step in creating a modern and comfortable urban environment in the conditions of the Rostov region. Meth-ods are proposed to compensate for negative changes in urban landscapes that can be applied at the stage of urban planning. As well as the proposed methods can be applied in the reconstruction of urban low-rise buildings. The considered methods concern not only urban landscapes, but also agricultural landscapes that surround small and medium-sized cities of the Rostov region. In article the author's concept of the organiza-tion of the low housing estate on a basis Urban- facies is submitted. Planning methods of regulation of water balance of the territory on the basis of models the ecological protective of landscapes are offered: an ecolog-ical core, an ecological corridor and an ecological barrier and also analogs from town-planning practice are considered. The reclamation of urban landscapes based on urban planning methods for regulating the water balance of the territory will allow creating unique urban spaces that are resistant to local climatic conditions and the possible consequences of climate change.

The article provides an overview of spatial and legal solutions related to the issue of water management in cities in the context of climate change. The aim of the research is to identify the main differences between the traditional and integrated approaches to water-related infrastructure based on case studies of European Cities at different scales. Gathering, ordering and comparing adequate solutions will allow to establish guidelines for the development of Polish cities and point out directions for architects and urban planners designing urban spaces. The comparison of good examples with theory would make it possible to verify whether practise corresponds with theory, and whether it can actually - through the synergy of measures – bring new quality to urban areas.

Cities For Climate Protection

Abstract The article concerns urban spaces highly responsible for climate change in the country, Europe, and the world. This topic is now of major importance because it reflects on every citizen of Europe and the world in that we all confront the necessity of climate protection and adaptation also in law, to climate change in urban areas. It is associated with a radical change of lifestyle in the world’s cities, mainly in terms of energy consumption and its methods of production. The research results presented in the article indicate the need to adapt current methods for slowing down adverse climate change into functional and spatial systems of urban development and their economic, legal, and social conditions affecting the pace of implementation of new technologies for climate-friendly sources such as low-carbon, energy-saving, and renewable energy. Attention was also paid to the possibility of ecological revitalization of the existing urban structure of buildings, among other things, in order to significantly reduce greenhouse gas emissions adversely affecting the climate. On the other hand, modern ideas for an Eco-City and solutions for a Green-City and Solar-City, presented in the article, implemented through sustainable development in the field of planning activities and energy management methods, can be additional indicators of the direction of sustainable development for Polish cities for climate protection and adaptation to its changes.

Rising global sea level, a consequence of climate change, results from an increase in the world ocean’s water volume and mass. Recent climate warming is responsible for producing the highest rate of global average sea-level rise of the past few millennia, and this rate will accelerate through the 21st century and beyond, exposing low-lying islands and coastal regions to significant flood risks. The flood risks can be compounded or diminished locally because changes in sea level are not uniform. In this review, we briefly discuss ice sheets as drivers of global and local sea levels, and how they could evolve under modern climate change. We underline some of the impacts of sea level change on coastal communities, and emphasize that local sea-level projections can be very different from estimates of the global average.

Abstract. As China is urbanized, flooding has become a regular feature in major cities. Assessing potential urban flood risks under climate change has become crucial for better managing such risks given the severity of the devastating disasters (e.g., the current 2016 flooding across China). Although the impacts of future climate change on urban flood risks have been investigated in many existing studies, the effects of both climate mitigation and adaptations have rarely been accounted for in a consistent framework. In this study, we assess the benefits of (1) avoided greenhouse gas (GHG) emissions and (2) adapting drainage systems on urban flood risks within the context of global warming through a case study in the Northern China. The urban drainage model, Storm Water Management Model (SWMM), was employed to simulate urban floods under current conditions and two feasible adaptation scenarios (i.e., pipe enlargement and low impact development), driven by bias-corrected meteorological forcing from five general circulation models (GCMs) in the Coupled Model Intercomparison Project Phase 5 (CMIP5) archive Based on the results, the volume of urban floods is projected to increase by 52 % in the period of 2020–2040 when compared to that in 1971–2000 under the business-as-usual scenario (i.e., Representative Concentration Pathways (RCP) 8.5). The magnitudes of urban floods are found to increase nonlinearly with changes in precipitation intensity, and highest risks associated with floods with smaller return periods below 10 years are identified. Despite the high level of uncertainty, it is obvious that avoided greenhouse emissions will be beneficial in terms of reducing risks associated with urban floods. On average, the magnitude of projected urban floods under RCP 2.6 is 13 % less than that under RCP8.5, demonstrating the importance of global-scale efforts on GHG emission reduction in regulating local to regional hydrometeorological responses. Moreover, the two feasible adaptation scenarios are shown to be able to further reduce risk associated with floods effectively. This study highlights the importance of accounting for local climate adaptation efforts in assessing urban flood risks under a changing climate.
