Green and Blue Infrastructure (GBI) are natural spaces, which strategically host diverse types of ecosystems to provide multiple social, economic, environmental, and ecological benefits to both wildlife and people. Urban GBI consists of land and/or water bodies that are predominantly made up of unsealed, permeable, natural surfaces, including ‘green’ vegetated grounds and ‘blue’ water bodies in cities. Through environmentally cautious and scientifically informed land use, GBI can provide multiple ecosystem functions, such as food production, water purification, temperature regulation, carbon sequestration, wildlife habitats, humanistic and aesthetic benefits, for underpinning quality of life and climate resilience of cities.
This SI will focus on understanding innovative GBI strategies that cities have developed to address the growing urban challenges, being made more severe by past, present and anticipated impacts of climate change and land alteration.
An increasing number of cities have used GBI for moderating urban heat island effects (e.g. New York, USA; Melbourne, Australia), managing surface runoff (e.g. Seattle, USA; Rotterdam, Netherlands; Curitiba, Brazil), storing carbon (Durban, South Africa), producing locally accessible food (Tokyo, Japan; Taipei, Taiwan); and conserve biodiversity (Durban, South Africa). GBI related practices often bring wider benefits to the social-ecological system of cities that are critical for place making and community coherence. Ecosystem functions delivered from GBI are local specific and thus the decision on GBI influence spatial equality in a city. However, there’s no one-fit-to-all strategies and trade-offs are often found between functions of GBI across different development scales and alternatives.
Thus, authors looking into multiple dimensions of GBI in cities are invited to prepare research articles for this issue. The issue will shed new light on ways to improve GBI , in cities by developing new concepts and approaches to understand how to assess, build, monitor and govern GBI solutions and policies.
This SI provides the opportunity for scholars, practitioners and governmental officials to co-work to gain more complete understandings on how cities can generate and manage GBI solutions that have large, short and long-term positive benefits in terms of natural resource management and which tackle global challenges such as climate changes, biodiversity loss, air pollution, water quantity and quality management and aesthetics for better human life-styles.
This SI is designed to facilitate the generation of knowledge to understand GBI at different levels, in diverse urban sectors, particularly on processes and approaches that can provide effective lessons on how to design interventions that can promote sustainability in cities and metropolitan regions. Thus, the Editorial Team of this SI invites authors to prepare and submit papers from diverse urban sectors, such as water, food, energy and building, as well as on integrated approaches that document lessons learned from cross-sectoral and multi-level analyses of the GBI impacts on environmental, social, economic, health, energy and security dimensions of urban and surrounding regions.
The Editorial Team welcomes review papers, research papers, and case studies that include but are not restricted to the following topics related to GBI:
Innovation.Assessment of the innovative changes in GBI and its trade-offs and co-benefits with the UN Sustainable Development Goals;
Spatial planning.GBIs and their roles in fulfilling improved spatial planning and governance in cities;
Security.Impacts of GBIs on water security, energy security and food security;
Nexus.Role of GBIs in underpinning urban water-food-energy nexus;
Climate Change.Impacts of GBIs on climate change mitigation and adaptation;
Biodiversity.Impacts of GBIs on urban biodiversity;
Resilience.GBIs and urban resilience to disasters;
Barriers.Barriers that hinder innovative and integrated GBI approaches using GBIs to manage at different scales, the common features of diverse types of interventions;
Social equality.Decision making, planning and development of GBI that helps to improve equality beween urban societies.
Capabilities.GBI-based innovations that helped to change cities in positive ways with a special focus upon the capabilities cities had to innovate and how they had to develop and implement those capabilities,
Policy making and implementation.Approaches used to overcome the barriers that make implementation of GBI initiatives in cities more difficult in practice;
Design and Frameworks.To design a framework guide of best practices and tools to foster GBIs with better urban interventions and more effective decision-making processes.
Project level design and management.Investigate the main factors related to project design or management (e.g., finance, training) that explain the effectiveness of GBI initiatives. Such cases may also reveal the project’s role(s) in catalyzing larger efforts throughout the same city/region and in other cities/regions;
Multilevel governance.Some of the local initiatives are led by grassroots efforts and others are the results of national level policies. How can policies be improved to more effectively build upon the lessons learned from different initiatives in many different cities/regions and countries?;
Laws and institutions. Analyze the role of laws, policies and institutions (e.g., informal rules or norms) to promote or hinder GBIs. Authors are encouraged to address how legal actors and alignment of the law in different levels of government, can block or encourage the development of GBI initiative;
International mechanisms.Some international mechanisms, such as international cooperation, and global mechanisms have been important to spur GBIs. Authors are invited to address these types of interactions, which may catalyze improvements in these types of efforts.
