Seite - 94 - in Biodiversity and Health in the Face of Climate Change

94 published within the last 5  years (2013–2017, Fig.  5.1). The analysis was therefore restricted to papers published in English from 2013 onward to highlight recent advances in the subject. Web of Knowledge© was used as the scientific search engine to find appropriate articles. The search profile was based on a number of primary search terms related to particular categories related to the topic. The first main term related to the topic ‘urban green’, the second to ‘availability’ and ‘access’, the third to socio-economic and socio-demographic profile of neighbourhoods or affected populations, and included key search terms such as ‘income’, ‘age’ or ‘class’, and the fourth to health including terms such as ‘health’, ‘disease’ and ‘well-being’. The respective terms were chosen based on the author’s own experiences with the topic and other reviews, existing theories and initial literature studies that revealed some inconsistent relationships on the green space associability link. The operators AND between and OR within categories were used. It was decided to restrict the search to scientific peer-reviewed papers. Excluded from the literature search were research reports and other non-scientific publications or bibliographies. However, these were used in searches for additional literature as was done with other existing reviews that touched on the topic (Kabisch et  al. 2017; van den Bosch and Ode Sang 2017). Articles found through the search strategy were screened and included in the final sample if the content matched the main research objectives. An article was evalu- ated as not relevant if no direct link to health outcomes related to urban green could be found, or when the article presented a method only as main content. This strategy resulted in a total of 25 papers. All final articles were analysed using a standardised data extraction sheet based on pre-defined questions for review. This included gen- eral information such as publication date, case-study location, respective scale of interest, particular assessment method or data used.
