“…Further, the scenario projections concerning climate variability add value in robust planning of city-scale mitigation strategies. 39 For instance, a study by Vemula et al on Hyderabad City, India, 30 shows that the present stormwater design falls short for future climate change scenarios. The combined information on flooding extent (by accounting for the stormwater drainage conveyance capacity) and potential vulnerability to the road network should culminate into the flood warning system.…”

Urban floods are paralyzing surface transportation and inflicting heavy economic losses. Climate-induced increase in frequency and intensity of rainfalls and excessive urbanization makes urban centers even more vulnerable to floods. It is necessary to quantify all dimensions of losses caused to road connectivity to improve flood mitigation policy. There is a need to consolidate the existing body of peer-reviewed contemporary literature on flood inundation modeling and its impacts on road connectivity. This will improve the awareness of policymakers and researchers and help in science-based decision making. Articles archived in the Web of Science database having the keywords floods and road in their title published between 1977 and 2020 were analyzed using the blibliometrix library of R. Analysis shows that the flood inundation and flood extent modeling has evolved from the conventional hydrological models to the near real-time crowd-sourced modeling methods. Applications of geographical information systems and advanced remote sensing methods have been growing in identifying road network vulnerabilities. We observed a gap in harmonized data availability, due to the unstructured data formats at several scales, which hinders a generalized approach for flood risk modeling studies for urban planning. Concentrated efforts have to be made to fill the gaps in data availability and research methodologies, especially using crowd-sourced data. Further, efforts have to be made to increase awareness, early warning systems, and alternate transport networks, to make the cities less vulnerable to floods.

“…The model is particularly suitable for policymakers and researchers in comparing multiple development scenarios and their trade-offs with ecosystem services. For instance, the model is applied for studying carbon sequestration (Babbar et al 2021), sediment retention (Hamel et al 2015), urban heat mitigation and energy conserved due to various land-use scenarios (Kadaverugu et al 2021b), flood retention service from green and open spaces (Kadaverugu et al 2020), among others. The present study used Coastal Blue Carbon (CBC), Nutrient Delivery, and Sediment Delivery sub-models of .0 suit.…”

Mangrove habitats play a vital role in balancing the coastal ecosystems by providing an array of provisioning, regulating, cultural, and supporting ecosystem services. Despite several conservation measures taken to protect mangroves, they have been facing economic, socio-environmental, and climatic threats. There is a need to quantify the mangroves' ecosystem services (ES), especially in developing and under-developed nations, to fasten up the mangrove conservation. To address this issue, in the present study, we quantified the ES of the mangroves in Odisha State on the eastern coast of India. And we projected the changes in ES according to the plausible future land-use changes using scenario analysis. The plausible future scenarios (by 2030) have been generated based on the participatory surveys and key informant interviews from the stakeholders in the region. The scenarios encompass socio-economic development, infrastructural development, mangrove conservation, agriculture and aquaculture expansion, and climate change. Coastal blue carbon sequestration, sediment retention and export, and nutrient export were quantified using the InVEST (Integrated valuation of ecosystem services and trade-offs) model. Results indicate that disturbances to mangrove forests in Odisha can emit 2.16 Tg C back into the atmosphere by 2030. In an optimistic scenario, mangroves can sequester 1.55 Tg C from the atmosphere. An increase in mangrove and green cover has reduced sediment and nutrient export by a maximum of 24.9% and 7.6%, respectively. The findings will help in evidence-based decision-making about the socio-environmental systems comprising sensitive mangrove ecosystems.

“…With the aim of quantifying the effects of the abundance and spatial configuration of the tree canopy cover on urban heat mitigation, a set of synthetic scenarios are generated by increasing different proportions of tree canopy cover in distinct spatial configurations. Although other studies have applied spatially explicit models of heat mitigation to evaluate future urbanization scenarios [38][39][40], the key novelty of this article is that scenarios are not defined to reflect specific planning strategies, e.g. business as usual, intensification, greening and the like, but rather to meticulously explore the effects of the spatial pattern of the tree canopy on urban heat mitigation.…”

Evaluating urban greening scenarios for urban heat mitigation: a spatially explicit approach

et al. 2021

Urban green infrastructure, especially trees, are widely regarded as one of the most effective ways to reduce urban temperatures in heatwaves and alleviate the adverse impacts of extreme heat events on human health and well-being. Nevertheless, urban planners and decision-makers are still lacking methods and tools to spatially evaluate the cooling effects of urban green spaces and exploit them to assess greening strategies at the urban agglomeration scale. This article introduces a novel spatially explicit approach to simulate urban greening scenarios by increasing the tree canopy cover in the existing urban fabric and evaluating their heat mitigation potential. The latter is achieved by applying the InVEST urban cooling model to the synthetic land use/land cover maps generated for the greening scenarios. A case study in the urban agglomeration of Lausanne, Switzerland, illustrates the development of tree canopy scenarios following distinct spatial distribution strategies. The spatial pattern of the tree canopy strongly influences the human exposure to the highest temperatures, and small increases in the abundance of tree canopy cover with the appropriate spatial configuration can have major impacts on human health and well-being. The proposed approach supports urban planning and the design of nature-based solutions to enhance climate resilience.
