What the kind of urban spaces are good for spatial resilience?4 answersUrban spaces that are good for spatial resilience include interstitial spaces, leftover spaces, public spaces, and green open spaces (GOS). Interstitial spaces, as highlighted in, are ambiguous areas within the city that can be repurposed for new functions, enhancing urban resilience. Leftover spaces, discussed in, can be transformed through creative and playful programs, contributing to the resilience of the urban landscape. Public spaces, as emphasized in, play a crucial role in responding to public health emergencies and maintaining the basic operation of the city. Additionally, GOS, as mentioned in, are essential for sustainable urban development and can be revitalized to improve the quality of life and resilience of urban ecosystems. By utilizing these diverse types of urban spaces, cities can enhance their spatial resilience and adaptability to various challenges.
What is the importance of biodiversity for ecological resilience.?4 answersBiodiversity is crucial for ecological resilience as it helps maintain ecosystem stability and functionality under increasing stress. Functional redundancy, which arises from having many species performing the same function, is an important aspect of resilience. Higher levels of biodiversity, including interspecific, intraspecific, and ecosystem diversity, contribute to functional redundancy and enhance resilience. However, it is important to note that not all relationships within biodiversity contribute to resilience. In some cases, higher diversity can actually promote collapse if it occurs in a functional group that negatively influences the ecosystem state. Therefore, a holistic approach to biodiversity research and management is needed, considering all levels of biodiversity, to maintain ecosystem resilience in the face of global environmental change.
What is the place and importance of urban ecological network in urban planning with resilience approach?4 answersUrban ecological networks play a crucial role in urban planning with a resilience approach. These networks help to address the environmental challenges posed by urban expansion and fragmentation, and contribute to the conservation of biodiversity and ecosystem integrity. They also enhance the connectivity between habitat patches, improving the overall ecological environment of cities. By considering factors such as habitat quality, spatial patterns, and human interventions, ecological networks can be designed and optimized to support biodiversity conservation and green space planning in urban areas. Additionally, urban resilience depends on protecting biodiversity, managing water sustainably, reducing the effects of climate change, and ensuring social cohesion. Urban green spaces, which are an integral part of ecological networks, contribute to these dimensions of urban resilience and should be planned and designed with appropriate criteria and principles. Therefore, urban ecological networks are essential for promoting sustainable and resilient urban development.
What are the environmental risks of urban water resource resilience?3 answersUrban water resource resilience faces several environmental risks. These risks include the impact of climate change and changing weather patterns, which can lead to water scarcity and increased water demand. Natural disasters such as floods and heavy rains also pose a risk to urban water infrastructure, causing damage and disruption to water supply systems. Additionally, the vulnerability of water infrastructure to hazards like salinization and water depletion can threaten the sustainability and quality of water services. The exposure of urban ecosystems to water-related hazards and the sensitivity of these ecosystems to such hazards further contribute to the environmental risks. Overall, these environmental risks highlight the need for proactive solutions, adaptation to climate change, and the development of strategies to increase the resilience of urban water resources.
What are the characteristics of physical urban resilience?5 answersPhysical urban resilience is characterized by several key characteristics. These include redundancy and robustness, which are identified as two important factors contributing to the resilience of cities. Other characteristics that contribute to physical urban resilience include connectivity, independence, efficiency, resources, diversity, adaptation, innovation, inclusion, and integration. These characteristics are essential for cities to withstand and recover from natural disasters, climate change, and socio-economic crises. The physical infrastructure of cities, such as buildings, road networks, and open spaces, also plays a crucial role in determining their resilience. Additionally, the study of urban form and its resilience can provide insights into the stability of urban systems. Understanding and incorporating these characteristics into urban planning and design can help cities build their physical resilience and effectively respond to future challenges.
How can we ensure that our cities are resilient and sustainable?2 answersTo ensure that our cities are resilient and sustainable, we need to take a comprehensive and integrative approach. This involves making choices on building design, waste management, urban ecosystem management, transportation, water, energy, and food systems that prioritize sustainability and resource efficiency. Additionally, it is important to address the challenges of urbanization and population increase, particularly in low-lying coastal areas, by improving infrastructure and resource allocation. Assessing sustainability indicators can help evaluate historical scenarios, current situational diagnoses, and future trends, while also promoting stakeholder engagement. Furthermore, innovation in areas such as urban technology, green infrastructure, food security, and integrated water planning can contribute to resilient and sustainable cities. Finally, governance and leadership play a crucial role in driving sustainable change, with a focus on creating sustainable cities through policy implementation and collaboration.
