“…Domestic gardens are a key element of urban green space and are an integral part of urban environments (Gupta et al, 2012). Urban green space is open space within a city boundary with vegetation cover planted deliberately or inherited from pre-urbanisation vegetation (Jim and Chen, 2006), covering a mixture of landscape types including public parks, sports grounds and all natural areas inclusive of domestic gardens.…”

• Front gardens in urban areas have seen a change in land cover.• This change is a shift from permeable to impermeable surfaces, for car parking.• This amounts to an average of 22.47% of land area, over a twenty year period.• Meanwhile the required attenuation storage volumes have increased by 26.23%.• Our study indicates an increase in flood risk in known flooding hotspots. a b s t r a c t a r t i c l e i n f o This study addresses the consequences of widespread conversion of permeable front gardens to hard standing car parking surfaces, and the potential consequences in high-risk urban flooding hotspots, in the city of Southampton. The last two decades has seen a trend for domestic front gardens in urban areas to be converted for parking, driven by the lack of space and increased car ownership. Despite media and political attention, the effects of this change are unknown, but increased and more intense rainfall, potentially linked to climate change, could generate negative consequences as runoff from impermeable surfaces increases. Information is limited on garden permeability change, despite the consequences for ecosystem services, especially flood regulation. We focused on eight flooding hotspots identified by the local council as part of a wider urban flooding policy response. Aerial photographs from 1991, 2004 and 2011 were used to estimate changes in surface cover and to analyse permeability change within a digital surface model in a GIS environment. The 1, 30 and 100 year required attenuation storage volumes were estimated, which are the temporary storage required to reduce the peak flow rate given surface permeability. Within our study areas, impermeable cover in domestic front gardens increased by 22.47% over the 20-year study period and required attenuation storage volumes increased by 26.23% on average. These increases suggest that a consequence of the conversion of gardens to parking areas will be a potential increase in flooding frequency and severity -a situation which is likely to occur in urban locations worldwide.

“…This type of small green spaces is generally located in consolidated urban centres, which may have a strong connection with the local lifestyle, having a social action component (Herzele & Wiedemann, 2003). There is a long-lasting tradition in research that explores the relationship between the characteristics of proximity and the individual well-being (Macintyre & Ellaway, 2000in Tzoulas et al, 2007: it has been proved that the level of proximity and the availability of green spaces affect the quality of the environment, helping in restoring stress, increasing the feeling of safety (Maas et al, 2009), the social interaction and the real estate value (Jim & Chen, 2012in Gupta et al, 2012 and also providing a recreational space for the physical and mental development of children (Jacobs, 1961in Gupta et al, 2012.…”

ABSTRACT:The identification of service areas of urban green spaces and areas with lack of these is increasingly necessary within city planning and management, as it translates into important indicators for the assessment of quality of life. In this setting, it is important to evaluate the attractiveness and accessibility dynamics through a set of attributes, taking into account the local reality of the territory under study. This work presents an operational methodology associated with these dynamics in local urban green spaces, assisting in the planning and management of this type of facilities. The methodology is supported firstly on questionnaire surveys and then on network analysis, processing spatial data in a Geographic Information Systems (GIS) environment. In the case study, two local green spaces in Lisbon were selected, on a local perspective explorative approach. Through field data, it was possible to identify service areas for both spaces, and compare the results with references in the literature. It was also possible to recognise areas with lack of these spaces. The difficulty to evaluate the dynamics of real individuals in their choices of urban green spaces and the respective route is a major challenge to the application of the methodology. In this sense it becomes imperative to develop different instruments and adapt them to other types of urban green spaces.

“…Urban heat island and air quality research often rely on these vegetation indices [58,71] to calculate the cooling effect of vegetation, to quantify the role vegetation plays in improving air quality [72], and links to socioeconomic patterns [73]. Researchers have also explored how urbanization has altered net primary productivity (NPP) [74] showing losses in temperate regions and decreases in arid regions [75]. Vegetation indices are also used to model changes in surficial biogeochemistry such as nitrogen across an urban gradient showing differences between high density urban, suburban, and rural areas [48].…”

This paper reviews how remotely sensed data have been used to understand the impact of urbanization on global environmental change. We describe how these studies can support the policy and science communities' increasing need for detailed and up-to-date information on the multiple dimensions of cities, including their social, biological, physical, and infrastructural characteristics. Because the interactions between urban and surrounding areas are complex, a synoptic and spatial view offered from remote sensing is integral to measuring, modeling, and understanding these relationships. Here we focus on OPEN ACCESSRemote Sens. 2014, 6 3880 three themes in urban remote sensing science: mapping, indices, and modeling. For mapping we describe the data sources, methods, and limitations of mapping urban boundaries, land use and land cover, population, temperature, and air quality. Second, we described how spectral information is manipulated to create comparative biophysical, social, and spatial indices of the urban environment. Finally, we focus how the mapped information and indices are used as inputs or parameters in models that measure changes in climate, hydrology, land use, and economics.
