“…Further adaptation examples can be found in urban areas near the Fraser River floodplain, an area that is highly vulnerable to sea level rise due to low-lying geology and dense population (Yumagulova and Vertinsky 2017). A recent analysis found that the costs of sea level related damage to on-shore built infrastructure would be higher in coastal BC than any other coastal region in Canada (Withey et al 2016).…”

Planning for adaptation to climate change requires regionally relevant information on rising air and ocean temperatures, sea levels, increasingly frequent and intense storms, and other climate-related impacts. However, in many regions there are limited focused syntheses of the climate impacts, risks, and potential adaptation strategies for coastal marine areas and sectors. We report on a regional assessment of climate change impacts and recommendations for adaptation strategies in the NE Pacific Coast (British Columbia, Canada), conducted in collaboration with a regional planning and plan implementation partnership (Marine Plan Partnership for the North Pacific Coast), aimed at bridging the gaps between climate science and regional adaptation planning. We incorporated both social and ecological aspects of climate change impacts and adaptations, and the feedback mechanisms which may result in both increased risks and opportunities for the following areas of interest: “Ecosystems”, “Fisheries and Aquaculture”, “Communities”, and “Marine Infrastructure”. As next steps within the region, we propose proactive planning measures including communication of the key impacts and projections and cross-sectoral assessments of climate vulnerability and risk to direct decision-making.

“…This allowed for collaborative efforts to take place in order to support a specific targeted adaptation agenda in the City of Vancouver and the region broadly. Yumagulova and Vertinsky (2017) characterize this approach as a reactive strategy and suggest that the majority of such structural developments have been motivated by the damage caused by devastating flood events like the 1948 Fraser flood. This response was also prompted by other factors including a lack of federal and provincial responsibility regarding hazard mitigation, inadequate floodplain mapping, in addition to insufficient oversight of municipal land use policies by higher levels of government (Yumagulova & Vertinsky, 2017).…”

This study explores the interaction between adaptation, resilience, resident perceptions of risk management, and flood policy in Vancouver, British Columbia. A systematic policy analysis determines how four adaptation strategies (protect, accommodate, retreat, and avoid) are employed in the municipality and interprets the degree to which current flood risk reduction efforts are capable of enhancing resilience across three conceptualizations established in literature (resistance, recovery, and creative transformation). Survey analysis of how residents understand and prioritize the concept of resilience is then applied to policy analysis findings to reveal a misalignment of policy targets and expectations. Findings indicate that protect and accommodate strategies dominate policy to compensate for ongoing floodplain development while the retreat and avoid strategies are ignored despite their utility in addressing exposure. Such policy fails to align with resident perceptions that resilience defined by creative transformation should be the objective of flood adaptation efforts.

“…Notably, rooftops can be a good alternative for increasing green spaces in cities where additional space is difficult to secure owing to high land prices and various conflicts of interest [9,10]. As a result, several studies [11][12][13][14] were conducted to effectively create rooftop greening and roadside trees in cities. Meyer [11] proposed a conceptual description of the individual effects of trees and offers a guideline for tree planting to increase such effects.…”

Urban green spaces offer various ecosystem services such as those for controlling the urban microclimate, improving water circulation, and providing leisure and recreation opportunities. However, it is almost impossible to create new, large green spaces in cities where urbanization has been long underway. Consequently, small-scale green spaces such as green roofs and roadside trees are gaining attention as features that can increase the effects of ecosystem services. Although the area of individual buildings in urban areas is relatively small, the sum of building rooftop areas account for a large portion of urban areas. Moreover, there are areas widely available throughout cities where street trees could be planted. However, this requires large amounts of accurate databases (DBs) and long-term spatial analyses to identify specific locations suitable for small-scale green facilities on a citywide scale using a geographic information system (GIS). Consequently, in-depth research on this topic has been insufficient. Thus, this study presents an algorithm to analyze locations where green roofs and roadside trees could be introduced based on GIS spatial analysis and verifies the effectiveness of the algorithm built for the city of Seoul. In addition, computational fluid dynamics (CFD) modeling is performed to analyze the temperature reduction effect, the representative function of ecosystem control services that can be brought about by the potential green spaces. The results show that rooftop greening in study areas is possible in 311,793 of 742,770 buildings. The rooftop floor area of buildings that can apply rooftop greening is 33,288,745 m2, which is about 50% of the total area of the rooftop in Seoul. It was found that roadside trees could be planted on a sidewalk with an extension length of 872,725 m and an area of 838,864 m2. A total of 145,366 trees can be planted in the study area. In addition, it was shown that the introduction of green roofs reduced temperatures by 0.13 °C to 0.14 °C and roadside trees reduced temperatures by 0.14 °C to 0.6 °C. With the growing need to improve urban ecosystem services as a result of rapid climate change, the algorithm developed in this study can be utilized to create spatial policies that expand and manage urban green spaces and thereby contribute to the improvement of urban ecosystem services.
