Urban Green Infrastructure

Historic allées and urban avenues reflect a far-sighted and forward-thinking design attitude. These compositions are the living witnesses of olden times, suggesting permanence. However, the 20th century’s urban development severely damaged the environment, therefore hundred-year-old mature trees are relatively rare among city avenues’ stands. Due to the deteriorated habitat conditions, replantation may be necessary from time to time. However, there are a large number of replanted allées and urban avenues considered historical monuments, according to the relevant international literature in urban and living heritage’s preservation. The renewal often results in planting a different, urban tolerant taxon, as seen in several examples reviewed. Nevertheless, the allée remains an essential urban structural element, though often with a changed character. The Budapest Andrássy Avenue, a city and nature connection defined in the late 19th century’s urban landscape planning, aimed to offer a splendid link between city core and nature in Városliget Public Park. The 19–20th century’s history and urban development are well documented in Hungarian and several English publications, though current tree stock stand and linear urban green infrastructure as part of the urban landscape need a detailed survey. The site analyses ran in 2020–early 2021 created a basis for assessing the allées and the whole avenue as an urban ecosystem and a valuable case study of contemporary heritage protection problems. Andrassy Avenue, the unique urban fabric, architecture, and promenades have been a world heritage monument of cultural value since 2002. The allées became endangered despite reconstruction type maintenance efforts. The presented survey analyses the living heritage’s former renewal programs and underlines the necessity of new reconstruction concepts in urban heritage protection. We hypothesize that urban green infrastructure development, the main issue in the 21st century to improve the urban ecological system and human liveability, may support heritage protection. The Budapest World Heritage Site is worthwhile for a complex renewal where the urban green ecosystem supply and liveable, pedestrian-friendly urban open space system are at the forefront to recall the once glorious, socially and aesthetically attractive avenue.

<p>Surface water flooding is the most likely cause of flooding in London, still affecting at least 3% of the area and up to 680,000 properties. Urbanization and climate change are expected to increase the impacts of urban flooding in the near future. To mitigate such problem and provide resilient ecosystem services for Europe’s largest capital, Urban Green Infrastructure adaptations have been extensively used in the last two decades in conjunction with traditional grey infrastructure. Sustainability and efficiency of green infrastructure depend on the ability of plants to emulate the natural ecosystem water and carbon cycles in the city. Considering the expected rise in temperature, changes in rainfall patterns and intensification of the urban heat island effect, existing and planned green infrastructure solutions might be vulnerable to plant water stress. Since there will be much less space available to accommodate future changes in cities, it is extremely important to think about the system’s potential performance further ahead the construction. In this study we perform a detailed evaluation of representative London parks and rain gardens to mitigate flood risk under a changing climate. Specifically, we focus on the hydrological performance of urban raingardens (consisting exclusively of low stature plants) and urban parks (as a composite of low stature vegetation and urban forests) in London. The coupled water and carbon dynamics were evaluated using the ecohydrological model Tethys-Chloris (TeC) forced with the last generation climate change projections UKCP18. Based on our simulation we disentangle the composite effects of climate change, to plant physiological responses to elevated CO2 and changes in precipitation patterns and temperature.</p><p>Our results indicate that:</p><p>(a) Changes in weather severely affect plant efficiency during the 2<sup>nd</sup> half of the 21<sup>st</sup> century;</p><p>(b) Effectiveness of green infrastructure is strongly dependent on possible climate change outcomes;</p><p>(c) Within a certain range of plausible climate changes, for the 1<sup>st</sup> half of the 21<sup>st</sup> century positive effects of changes in climate can mostly counteract negative plant physiological responses to elevated CO2, but those negative effects gradually become dominant;</p><p>(d) Efficient and sustainable design of urban green infrastructure to mitigate flooding must consider an optimal adaptive choice of plants to offset the projected negative impacts of elevated CO2 and uncertain climate.</p>
