Understanding and conceptualizing how urban green and blue infrastructure affects the food, water, and energy nexus: A synthesis of the literature

Rodrigo A. Bellezonia, Fanxin Meng, Pan Hec, Karen C.Seto

Summary: The interactive dynamics in the food, water, and energy system as a nexus (FWEN) are critical to the sustainable development of global cities, and they can be mediated by green and blue infrastructure (GBI) in the urban area. Here we provide a comprehensive literature review to examine how GBI affects FWEN in urban centers, an area which is currently understudied. In order to do this, we undertake a systematic review of the literature using a meta-analytic approach and topic modelling. Based on our synthesis, we develop a conceptual framework of the key links between urban GBI and FWEN and the direction and magnitude of the relationship. We found that GBIs can benefit food supply, energy saving, and climate change mitigation but at a price of food safety and water contamination. Well-designed urban construction can help curb the negative effects. Therefore, we need to make deliberate and integrative policy to link GBI with each element in urban FWEN. Moreover, the focus of studies on GBIFWEN links is also heterogeneous across cities: urban agriculture and food security are priorities in cities located in Africa and Asia as well as in lower income and larger cities (but not metropolitan areas), while the cooling effect of green space has been a focus for cities of middle or high income. Finally, current research focuses on isolated analysis, lacking integrated studies needed for decision making supporting tools. While isolated analyses lead to connectivity failures and can result in adverse impacts, integrated analyses can identify interdependencies of environmental resources between parts of a cycle and across different scales, which can increase resource efficiency and minimize environmental degradation. Therefore, our key findings point out the importance of linking the effects of GBI on each component of FWEN in both research and policy making.

Effects of COVID-19 on the Sustainable Development Goals (SDGs)

Summary: Global crises caused by the pandemic of COVID-19, since early 2020, can compromise the world commitment to the 2030 Agenda for Sustainable Development. This study discusses critical aspects of the global pandemic for the achievement of the Sustainable Development Goals (SDGs). More precisely, we analyze how the new circumstances created by the pandemic have affected the interdependencies between SDGs. Following a synopsis of the current literature, we focus on effects regarding SDG3 (Health & Well-Being), SDG4 (Quality Education), SDG8 (Decent Work & Economic Growth), SDG12 (Consumption & Production) and SDG13 (Climate Action). Following a qualitative research approach, we based our analysis on moderated focus group discussions (FGD). Our observations reveal a unique pattern of interconnectedness between SDGs that can be related to COVID-19 consequences. Qualitative interpretations of focus group discussions also depict, that additional spillover effects can be obstacles for achieving SDG 5 (Gender Equality), SDG 9 (Infrastructure & Innovation) and SDG 10 (Reducing Inequalities), SDG 17 (partnerships for the goals), SDG 11 (sustainable cities). Therefore, we consider the interdependent implications and recent trends in international development related to sustainability as a useful framework in the post-pandemic recovery period.
