The focus of this research is to check if urban crime is related to the social spatial urban structure and to identify the most unsafe territories in the city of Klaipeda from the point of view of crime and urban structure. Space syntax theory and method, as well as correlation analysis have been used for this purpose. The research results have revealed that all types of crimes depend on global integration and global depth: the more integrated and shallow the open public spaces are the more crime incidents in these spaces happen.

In this study, ideal but realistic numerical experiments are performed to explore the relative effects of changes in land use and emission distribution on air quality in the Pearl River Delta (PRD) region in winter. The experiments are accomplished using the Lagrangian particle transport and dispersion model FLEXPART coupled with the Weather Research and Forecasting model under different scenarios.

In this study, the impact of different urban development scenarios on neighbourhood climate are examined. The investigation considers the relative impact differing policy/planning choices will have on the local-scale climate across a city during a typical climatological year (TCY). The aim is to demonstrate a modelling approach which couples a climate-based land classification and simple urban climate model and how this can be used to examine the impact differing urban forms and design strategies have on neighbourhood scale partitioning of energy and resulting consequences.

Given the regional geographic specificities of Central Andean valleys, the social and environmental impact of dispersed urbanization on smallholder farmers is particularly high in the new urban peripheries of Peruvian mountain cities.

Collaborative planning processes have been criticized for inefficiency, but attempts to improve them in planning of urban nature have been limited by lack of usable evaluation methodologies. This paper presents a framework for evaluating and designing collaborative processes in strategic planning of land use and nature areas. A framework with four key perspectives and their success criteria was developed with the help of literature and data from interviews and focus groups in two case areas in the Helsinki metropolitan area, Finland.

Woodland fragments, in small historical cities, are commonly regarded as temporary voids in an urban matrix, yet to be allocated a land-use, under city planning regulations. However, they could display relevant plant diversity, and contribute to urban ecosystem services. This study combined surveys at 100 m², and at patch level, with the aim to investigate how patch size, stand and urbanization, affected the structure of plant communities in thirty woodland fragments (0.1–2 ha), spontaneously developing in the small, historical city of Padova (Northern Italy).

The relationship between sustainable urban development and environmental sustainability is crucial to every strategy of urban transformation, renewal and regeneration. In particular, urban regeneration entails programmes of urban transformation that involve the rehabilitation of existing parts of a city, re-use previously built-up area and abandoned buildings, and redevelop blighted urban spaces to increase urban sustainability.

This work describes a methodology for Strategic Environmental Assessment of urban areas in Latin America based on the recently approved European Planning Directive, and applies it to the Metropolitan Area of Concepción (Chile). The method is based on the Land Suitability Index (LSI), a cartographic GIS-based index originally developed for the region of Barcelona (Spain) and aimed at determining the suitability of each point in a region for urban development, considering three sub-indexes: (i) Naturalness, (ii) Ecological Connectivity and (iii) Natural Risk.

Cities are facing considerable challenges resulting from imminent climate change impacts. Urban planning to minimise adverse impacts of climate change at the city level can establish a climate-resilient city. Mitigation strategies to reduce CO₂ emissions would lead to a climate-friendly city. Integrating climate change adaptation and mitigation into sustainable city planning should not be merely added as a single level of sustainable city planning, but requires a wide range of multi-level cooperation.

Quantifying the urban landscape pattern and its change is fundamental for monitoring and assessing the ecological and socio-economic consequences of urbanization. Using Indian Remote Sensing Panchromatic (IRS-PAN) imagery of 2002 and combining gradient analysis with landscape metrics, we compared the landscape patterns between metropolises and small-sized cities with increasing grain size. Landscape metrics were computed along a 51 × 9 km transect cutting across Shanghai and a 16 × 2 km transect cutting across Zhangjiagang with a moving window.

Hollow-bearing trees provide habitat for diverse taxonomic groups and as such they are recognised for their importance globally. There is, however scant reference to this resource relative within urban forest patches. The functional ecology of habitat remnants along an urbanisation gradient plays an important ecological, social and economic role within urban landscapes. Here we quantify the impacts of urbanisation, landscape, environmental, disturbance (past and present) and stand variables on hollow-bearing tree density within urban forest patches.

Urban green areas are important sites established for recreational, ecological, and aesthetical purposes. Urban green areas are different form the other green space usage, can be used by the all parts of the community. Public green space standards, construction law No. 3194 of the plan to be built on the basis of 10 m² per person in the regulations "active green space" is defined as. About the amount of green space in the regulation applies to active green space. Active green space are defined parks, children's playground and play areas.
