CLUSTER C: PATTERNS OF LAND USE, SOCIAL FABRIC, AND CONSUMPTION
The modelling study on the relationship in the rural-urban interface between green areas and bio-physical and socio-economic variables and corresponding gradients bases upon the land use mapping of the German counterpart project C02 and the observation network of the Bangalore Development Agency. It will support the sustainable management of green spaces in the study area, for example, through identification of suitable composition and configuration of green spaces. As such, the outcome of the project will form an important basis for developing green spaces at the rural-urban interface and for devising corresponding management options. A comprehensive information base on the spatial pattern of green spaces will be complemented that will be of direct utility for informed decisions of policy planners in the Garden City of Bangalore. The structural diversity as assessed during this project and the German counterpart project C02 will be indicative also of overall biodiversity and habitat suitability and link, therefore, directly to the biodiversity related German and Indian projects. The assessment and description of spatial structures at reasonable and affordable cost is a key to manage urban green spaces. The knowledge of vegetation structure and development is an important input to informed planning of green spaces along the rural-urban interface in particular when it comes to monitor the development of these areas as a function of the manifold external natural (e.g. precipitation) and human-induced (e.g. pollution and soil compaction) factors.
In this project, we will assess relationships between variables like composition and configuration of green areas and bio-physical and socio-economic variables in urban areas, in peri-urban areas and in surrounding rural areas in Bangalore. We hypothesize that presence, pattern, and structure of green areas and their relationships to bio-physical target variables like urban heat and socio-economic target variables like average income exhibit gradients in multiple ways along the interface from urban to rural environments. Input data will partly be generated by this project, partly be taken from the Bangalore Development Agency and partly by project C02 of the German counterpart proposal.
The following work packages/analyses are envisaged which define at the same time the outcomes:
- Spatial pattern analyses of land uses and their development over time. This activity is closely related to the remote sensing based analyses of the German counterpart project C02 and focuses on the statistical analyses and description of status and transitions, which will be one basis of the identification of potential drivers of these changes.
- Analyses of the temperature pattern at the rural-urban interface as a function of the pattern of urbanisation and of green spaces, where the green spaces will be broken down into different classes like parks, alleys, gardens, scattered green plots, and agricultural fields. This analysis builds upon research on “urban heat islands” and will combine space-borne thermal remote sensing and ground measurements with a thermal camera supplied and also used by the German counterpart project C02.
- A comparison of different quarters of Bangalore regarding green areas will also be done.
The proposed project is methods-oriented and has a strong focus on quantitative analyses. The linking of variables and the modelling of relationships between variables will require close links to other projects that generate the corresponding data.
