What the latest science on climate change mitigation means for cities and urban areas
- 2022

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Summary for Urban Policymakers (SUP) initiative provides a distillation of the IPCC reports into accessible and targeted summaries that can help inform action at city and regional scales. Volume I in the series, What the Latest Physical Science of Climate Change Means for Cities, identified the ways in which human-induced climate change is affecting every region of the world, and the cities and urban areas therein. Volume II, Climate Change in Cities and Urban Areas: Impacts, Adaptation and Vulnerability, assessed the feasibility and effectiveness of different adaptation options. To achieve climate resilient development, synergies between policies and actions for climate change adaptation, mitigation and other development goals are needed.This third volume in the series, What the Latest Science on Climate Change Mitigation Means for Cities and Urban Areas offers a concise and accessible distillation of the IPCC Working Group III Report for urban policymakers. The 21st century is characterized by a rapidly growing urban population, urban land expansion and associated rise in demand for resources, infrastructure and services. These trends are expected to drive the growth in emissions from urban consumption and production through 2100, although the rate of urban emissions growth will depend on the type of urbanisation and the speed and scale of mitigation action implemented. Aggressive and ambitious policies for transition towards net zero greenhouse gas emissions can be implemented in cities and urban areas, while contributing to sustainable development. Ultimately, mitigation action and adaptation are interdependent processes, and pursuing these actions together can promote sustainable development.

Forskningsöversikt (refereegranskat)abstract
- Non-technical summary We identify a set of essential recent advances in climate change research with high policy relevance, across natural and social sciences: (1) looming inevitability and implications of overshooting the 1.5 degrees C warming limit, (2) urgent need for a rapid and managed fossil fuel phase-out, (3) challenges for scaling carbon dioxide removal, (4) uncertainties regarding the future contribution of natural carbon sinks, (5) intertwinedness of the crises of biodiversity loss and climate change, (6) compound events, (7) mountain glacier loss, (8) human immobility in the face of climate risks, (9) adaptation justice, and (10) just transitions in food systems.Technical summary The Intergovernmental Panel on Climate Change Assessment Reports provides the scientific foundation for international climate negotiations and constitutes an unmatched resource for researchers. However, the assessment cycles take multiple years. As a contribution to cross- and interdisciplinary understanding of climate change across diverse research communities, we have streamlined an annual process to identify and synthesize significant research advances. We collected input from experts on various fields using an online questionnaire and prioritized a set of 10 key research insights with high policy relevance. This year, we focus on: (1) the looming overshoot of the 1.5 degrees C warming limit, (2) the urgency of fossil fuel phase-out, (3) challenges to scale-up carbon dioxide removal, (4) uncertainties regarding future natural carbon sinks, (5) the need for joint governance of biodiversity loss and climate change, (6) advances in understanding compound events, (7) accelerated mountain glacier loss, (8) human immobility amidst climate risks, (9) adaptation justice, and (10) just transitions in food systems. We present a succinct account of these insights, reflect on their policy implications, and offer an integrated set of policy-relevant messages. This science synthesis and science communication effort is also the basis for a policy report contributing to elevate climate science every year in time for the United Nations Climate Change Conference.Social media summary We highlight recent and policy-relevant advances in climate change research - with input from more than 200 experts.

Tidskriftsartikel (refereegranskat)abstract
- Studies of infrastructure have demonstrated broad differences between Northern and Southern cities, and deconstructed urban theory derived from experiences of the networked urban regions of the global North. This includes critiques of the universalization of the historically-culturally produced normative ideal of universal, uniform infrastructure. We introduce the notion of “heterogeneous infrastructure configurations” (HICs) as a way to analyze urban infrastructure that builds on postcolonial critiques of knowledge, as well as ethnographies of everyday Southern urbanisms. We argue that the notion of HIC helps us to move beyond technological and performative accounts of actually existing infrastructures to provide an analytical lens through which to compare different configurations. Our approach enables a clearer analysis of infrastructural artifacts not as individual objects but as parts of geographically spread socio-technological configurations: configurations which might involve many different kinds technologies, relations, capacities and operations, entailing different risks and power relationships. We use examples from ongoing research on sanitation and waste in Kampala, Uganda- a city in which service delivery is characterized by multiplicity, overlap, disruption and inequality- to demonstrate the kinds of research questions that emerge when thinking through the notion of HICs.

Claiming value in a heterogeneous solid waste configuration in Kampala

Tidskriftsartikel (refereegranskat)abstract
- Kampala has a complex set of regulations describing actors, rules and procedures for collection and transportation of waste, and requires waste to be disposed of at the landfill. Yet little of the city’s waste moves through this “formal system”. Building on wider scholarship on urban infrastructure and calls to theorize from southern cities, we examine recycling in Kampala as a heterogeneous infrastructure configuration. Kampala’s lively recycling sector is socially and materi- ally diverse: it is comprised of entrepreneurs, public-private partner- ships and non-governmental organizations, as well as a range of materials with different properties and value. We articulate how actors assert claims, obtain permissions, build and maintain relation- ships as they rework flows away from the landfill. We argue that recognizing socio-material heterogeneity throughout the waste con- figuration enables a clearer analysis of contested processes of claim- ing value from waste. We also demonstrate how these efforts have pressured the state to reconsider the merits of the modern infra- structure ideal as a model for what (good) infrastructure is and ought to be. Various actors assert more heterogeneous alternatives, raising the possibility of alternative modes of infrastructure which might generate better incomes and improve service provision.
