Linking Health with Nature Experience: Restoration and Other - PowerPoint PPT Presentation

Linking Health with Nature Experience: Restoration and Other Pathways Terry Hartig Institute for Housing and Urban Research and Department of Psychology Uppsala University

Relation between amount of green space (in a 3 km radius) and self-perceived health (percentage stating their health is less than good), with controls for urbanity, sociodemographic and socioeconomic characteristics (from Maas et al., 2006).

Incidence rate ratios for deaths from circulatory disease in income-deprivation quartiles 2 – 4, relative to income deprivation quartile 1 (least deprived), stratified by exposure to green space (from Mitchell & Popham, 2008).

Restoration Cumulative effects

Logistic regression analysis of early retirement for health reasons among 19,221 men in Sweden during 1998-99, after 9 years of follow-up (from Hartig & Fransson, 2009). Variables OR (95% CI) Age in 1997 1.179 (1.157 to 1.202) 10-12 years education (ref: 6-9 years) 0.718 (0.513 to 0.865) 13+ years education 0.666 (0.586 to 0.878) Income from work 1997 0.862 (0.849 to 0.875) Family disp.

Relevance to biodiversity protection Restoration as a motive for nature protection

I need time in nature to be happy. Sometimes when I am unhappy I find comfort in nature. Being out in nature is a great stress reducer for me. Norwegian adults (N = 1293) endorsement of three statements about use of nature for psychological restoration (i.e., either agree or do not agree) (from Hartig, Kaiser, & Strumse, 2007).

The association between the use of nature for psychological restoration and general ecological behavior (from Hartig, Kaiser, & Strumse, 2007).

Relevance to biodiversity protection Constrained restoration and the ”pasteurization” of nature

Concluding remarks Progress is being made in building the body of evidence on the processes through with nature experience becomes linked with health. Psychological restoration is a key process. Restorative experiences in nature can help to support efforts to preserve biodiversity. Yet, the desire for restoration in nature may also hinder efforts to preserve biodiversity.
