“…Reducing thermal stress due to shadow casting and transpiration [7][8][9]; • The leaves in the canopy act as a filter for gaseous pollutants (NO 2 , SO 2 , O 3 , CO) and particulate matter (PM 10 , PM 2.5 ) [10][11][12]; • The canopy can intercept huge amounts of water during rainfall [13,14] which leads to decreased storm water runoff; • CO 2 sequestration through photosynthesis helps to reduce greenhouse gases from the atmosphere [15,16]; • Trees provide a habitat for different animal species groups like insects, birds and mammals [17,18] and enhance biodiversity in cities.…”

Cooling Effects and Regulating Ecosystem Services Provided by Urban Trees—Novel Analysis Approaches Using Urban Tree Cadastre Data

Abstract:The provision of ecosystem services by urban trees is not yet routinely integrated in city administrations' planting scenarios because the quantification of these services is often time-consuming and expensive. Accounting for these welfare functions can enhance life quality for city dwellers. We present innovative approaches that may appeal to the numerous city administrations that keep tree inventory or cadastre databases of all trees growing on city property for civil law liability reasons. Mining these ubiquitous data can be a feasible alternative to field surveys and improve cost-benefit ratios for ecosystem service assessment. We present methods showing how data gaps (in particular tree height and crown light exposure) in the cadastre data can be filled to estimate ecosystem services with i-Tree Eco. Furthermore, we used the i-Tree Eco output for a noval approach which focus on predicting energy reduction as a proxy for cooling benefits provided by trees. The results for the total publicly owned and managed street trees in our study site of Duisburg (Germany) show that the most important ecosystem services are the removal of particulate matter by 16% of the city emissions and the reduction of 58% of the direct and thermal radiation in the effective range of the trees in the cadastre.

“…It is based on the mapping of urban biotope types as well as an analysis ofterrestrial and aerial photographs. It enables the identification and description of all areas within a city characterized by vegetation according to type, size, structural characterization as well as density, structure and building type (Lehmann et al, 2014). Basic information about the area of investigation, its ecology, species, etc., is to be gathered and selected.…”

Abstract. The aim of this contribution is mapping and analysing of biotopes sensitivity in Antakya urban city with its surroundings. The three objectives were: (1) to identify the biotope types which display the structural characteristics of the study area, (2) to map the biotopes using object-oriented classification and (3) to determine sensitivity of these biotopes using rarity and reestablishment of research area. The study mainly carried out in two stages: the first one determination of biotope types using information from field surveys and aerial images; the second stage determination of biotope sensitivity to human disturbance. The sensitivity assessment based on two parameters; the rarity and the re-establishment ability of biotopes. Based on sensitivity results, 1.581 ha of the research area -forest, river banks and river and banks-is very sensitive, 454,6 ha of the research area -cemetery, settlement with site, and maquie-of land sensitive.

“…In addition, they serve to counteract or weaken the negative repercussions of inner-city heat islands, which frequently arise on hot summer days in urban areas with highly dense structures and extensive soil sealing (Matzarakis, 2001). One study that applied the HIRVAC model to examine the relationship between the structure of urban vegetation (in terms of the specific green volume) and the temperature lowering effect in 57 different urban structures (so-called urban vegetation structure types) confirmed that, alongside forest structure types, the structure types of green spaces in the urban environment displayed the greatest temperature lowering capacity (Lehmann et al, 2014). The question of how the cooling effects obtained by a city or an urban district are influenced by having one large as opposed to many smaller green spaces was investigated using the HIRVAC-2D model (Goldberg & Bernhofer, 2001) for a site of approx.…”

“…Open spaces provide a safe environment for wild plants and animals, help reduce levels of atmospheric and water-borne pollution, and last but not least, can play a decisive role in regulating the urban climate (Haase, 2001). A large number of case studies and scientific investigations have shown that one crucial ecosystem service of urban vegetation is its regulatory effect on the urban (miro-)climate (Bowler et al, 2010;Endlicher et al, 2008;Gill et al, 2007Gill et al, , 2009Lafortezza et al, 2009;Lehmann et al 2014, Nohl 1993Oke et al 1989;Wilmers, 1990;Alexandri & Jones, 2008). The type, size, and spatial distribution of public green spaces and water bodies are therefore key factors.…”

The type, size, and spatial distribution of public green spaces and water bodies are key factors for the microclimatic quality of urban areas, particularly within densely built-up districts, where they influence the quality of life. The analytical method presented in this paper looks at entire cities in a GIS-based approach that identifies potential critical areas of the city (with regard to heat stress or the accessability of green spaces) and quantifies their size and location in relation to green space and water bodies. The advantage of this method is that analysing the urban environment can be largely automated by the use of available geo base data. This requires the application of algorithms from the field of landscape ecology to the urban environment. The method is based on multifactorial evaluation. Comparisons between cities are made possible by extremum normalisation. Densely built-up areas as well as all green spaces and water bodies within settlements are quantified in the form of areal indicators. Thus the proximity of densely built-up areas to green space or water bodies is measured by the indicator "Euclidian distance." By correlating the resulting potential heat islands with population data from the 2011 National Census, it is possible to determine the likely number of residents affected. The method presented, which has been tested on seven cities in Germany, is part of a wide-ranging investigation into urban densities aimed at improving efficiency and environmental quality.
