Framework for designing greening strategy for cities based on the concept of ecosystem service flows
The greening process, rather than being limited to setting up of parks and amenities, should be an adaptation mechanism that counters the loss of natural landscapes resulting from urbanization. The proposed poster presents a comprehensive framework for designing a greening strategy for cities based on the concept of ecosystem service flows and benefits. The study demonstrates how simple measures can be employed to redefine the concept of a smart city to being ecologically and climatically smart; through customization of greenery to address local concerns like provision of nutrients to poorer sections of society, along with facilitating regulatory services such as climate amelioration, biodiversity conservation, etc. The outcome of such an ecologically designed greening strategy is in the form of a customized green plan right from a neighbourhood to a community and finally a city scale which is currently being implemented in Naya Raipur, India
Abstract: Urban parks are an important element of the urban green infrastructure. The urban park Parc des Moulins, is one of the largest green areas on the edge of the Troyes conurbation. We developed and conducted survey for the park users with the objective to determine the factors influencing the probability of park users’ willingness to pay (WTP) to enjoy an urban park in a medium-sized conurbation in the French context. To obtain a quick glance at how local governments and city planners see the benefits of parks, we developed an additional questionnaire.

Abstract: The mechanism of noise pollution propagation is considerably affected by 1) the type and configuration of its receiving environment and 2) the distance that sound waves pass to reach that environment. This study adopts a spatio-statistical approach to quantify and model associations between noise pollution levels and landscape metrics of land categories (built-up structures and urban green covers). Accordingly, noise levels were measured employing a sound pressure meter to quantify equivalent levels (Leq in dB A), in addition to their corresponding percentiles (L10 and L90). A collection of 30 sampling points were selected to measure noise data within the fall season and between 4 p.m. and 8 p.m. hours of the day. A hierarchical distance-sampling framework based on buffer areas with different radius (300m, 600 m and 1 km) around each sampling point was compiled to measure composition and configuration metrics of land categories within each buffer area. The results derived from Pearson correlation analysis and multiple-linear regression models indicated that there is a distance-dependent relationship between the metrics of green areas and noise levels. We didn’t find remarkable distance-dependency between built-up structures and noise levels. Based on our new spatio-statistical approach, we conclude that more connected and compacted pattern of green areas closer to pollution centers can significantly alleviate the effects of noise propagation mechanism and appropriate pattern of built-up areas follows a low density distribution with coming green areas in between. Findings of this study highlight the potential of landscape ecology approach as an effective planning paradigm for designing greener and calmer cities.

Abstract: In this paper we examine the performance of formal programs associated with tree plantings in Washington, D.C. and Baltimore, MD to understand the relationships between the implementation of urban greening programs and the social and ecological characteristics of a city. Previous research has examined variations in patterns of existing and possible tree canopy cover relative to different social theories. Less attention has been paid to the processes of how the current patterns of tree canopy cover have developed. The goal of this paper is to address this gap by examining current programs to increase tree canopy. This paper utilizes public records, administrative data, a geodemographic market segmentation database, and high-resolution land cover data to assess where programs work, who participates in these programs, and whom the programs fail to reach. Recruiting households to plant trees can be hard work. In this paper, we find that programs might be most successful where it is easiest but have the lowest need. Free or reduced-cost programs for tree planting on private lands were most effective in the most affluent neighborhoods of Washington, D.C. and Baltimore, MD. These areas tended to also have the most existing tree canopy on both private residential lands and the public right of way. An outcome of this research is a framework for further testing which land management strategies are most effective, where, and with whom in order to improve the ability to plan and enhance urban sustainability and resilience through urban forestry.
