Table 2 Protocol to adapt the ESTIMAP recreation model for the special use in this study
Step | Key questions | Consideration |
|---|---|---|
Type of knowledge production | • What is the application of the final map? | The final assessment maps can inform local planners of different conditions of NBR at the city scale. The spatially explicit information can help to identify key locations for developing urban green spaces |
• How are stakeholders involved? | Designing the model considering literature, demographic reports, and local plans related to elderly people | |
Spatial and temporal scale | • What temporal and spatial scales are considered? | The model concerns the biophysical conditions of nature and human inputs at the city scale. The model is expected to be representative in the near future due to consistent urban renewal and demographic changes |
Model rules | • What components should be included? | Based on evidence of elderly people's preferences for NBR (Loukaitou-Sideris et al. 2016; Wen et al. 2018), the components should reflect environmental features that affect different aspects of preferences. Spatial indicators for features are developed based on (1) whether they can represent elderly people’s NBR in urban areas, and (2) whether data are available at the city scale |
• How can we combine these components? | The model needs to include both the “overlay” approach and “advanced look-up table” approach (Paracchini et al. 2014). The former helps to study related features by combining them into one category, while the later helps to study two different categories of features by cross-tabulation | |
Get feedback | • Are there any verifying maps from independent data? | Several input map layers can be validated by multi-source datasets, especially for the physical environmental features. For example, landscape components and certain facilities can be acquired from other data sources, such as satellite images. However, the maps of landscape aesthetics and opportunities are yet to be verified. So far, there have been no field studies investigating recreation opportunities for elderly people in the study area. Although conducting a spatially explicit field survey across the region is beyond the scope of this modelling study, future participatory works (e.g., Public Participatory Geographic Information Systems—PPGIS) can be used to validate and refine the results |
