Approaches to providing sustainable energy in cities have generated considerable interest in academic and policy circles. The development of this body of work, however, has not shed much light on the modes of intermediation that are needed to reconfigure urban energy systems towards sustainability in energy-poor countries. This paper focuses on the role of academics as knowledge intermediaries who can trigger cross-sector collaborations around innovations for a sustainable energy transition in African cities. The research presented here was generated by an interdisciplinary research team made up of partners in Kenya, Uganda and South Africa. The research partners set out to better understand how sustainable energy transitions can be achieved through collaborative efforts between community members, experts and policy actors in the three countries. This paper provides evidence-based reflections on how the research partners used participatory methods to facilitate solution co-design and knowledge co-production over a period of two years under the Leading Integrated Research for Agenda 2030 in Africa (LIRA 2030) program. A key knowledge outcome of the research partnership is an improved understanding of how transdisciplinary research across the sub-region can be used to unearth the socio-spatial, cultural and political dimensions of energy in relation to other urban services such as health and housing. Based on this understanding, the paper proposes transdisciplinary co-design as a promising approach to providing sustainable energy in urban informal settlements in Sub-Saharan Africa."…leaders in government, the private sector and civil society to drive further, faster action toward achievement of Sustainable Development Goal 7, which calls for universal access to sustainable energy by 2030, and the Paris Climate Agreement, which calls for reducing greenhouse gas emissions to limit climate warming to below 2 degrees Celsius." [3].Launched at the UN General assembly in 2011, SEforALL has three main objectives of: "ensuring universal access to modern energy services, doubling the global rate of improvement in energy efficiency, and doubling the share of renewable energy in the global energy mix." (ibid).This paper focuses on the role of academics in this push for sustainable energy for all. As knowledge intermediaries, academics are well placed to facilitate cross-sector collaborations around innovations for sustainable energy transition, more so in the case of African cities that are some of the fasted growing in the world [4]. We reflect on our own work as knowledge intermediaries and integrators by situating our

Urban development in Africa is a very diverse and ambivalent phenomenon with aspects that do not fall neatly into global standards. Informal settlements therefore challenge governance by standards. We argue that quantifying and interrogating differences offers a better basis for governance. By drawing on a comparative analysis of three different informal settlements in Sub-Saharan Africa, this paper explores what differences reveal about the governance of informal settlements. The paper uses an urban societal metabolism approach, focussed on gender, energy and health, based on questionnaires and focus group discussions in Enkanini (Stellenbosch, South Africa), Mathare (Nairobi, Kenya), and Kasubi-Kawaala (Kampala, Uganda). The contribution of the paper is both empirical and theoretical. Empirically, we provide new evidence about the metabolism of urban informality at multiple levels of analysis: the individual, the household and the settlement. Findings show the gender asymmetries in urban poverty and the intricate links between energy choices, health and economic status. Theoretically, we argue that different levels of analysis produce different understandings of urban informality, and that analyzing informal settlements only by population aggregates means missing information. We conclude by arguing that understanding differences leads to the formulation of modest and localised goals, which are better able to take into account the complexity of urban informality.

a b s t r a c tThis paper assesses the different levels of uncertainty that affect the analysis of informal urban settlements and the implementation of upgrading policies, with a specific focus on electrification. The rapid growth of informal settlements in the cities of the Global South poses serious challenges to the management of energy systems, particularly when it comes to the electricity grid. Informal urban settlements are characterized by the lack of urban planning and low or absent provision of public services. Exponential population growth increases the complexity of urban planning. An inadequate understanding of uncertainty can undermine the effectiveness of informal settlement upgrading and deepen social inequalities. Based on the case study of the Enkanini settlement in Stellenbosch, South Africa, this paper probes three levels of uncertainty: (i) methodological uncertainty associated with the challenge of estimating energy demand and demographic changes, (ii) technical uncertainty associated with the expansion of the electric grid and securing revenues, and (iii) epistemological uncertainty associated with the definition of the relevant problems and pertinent solutions for informal settlements. The paper highlights how the focus of technical uncertainty displaces the debate on the socio-political challenges of informal settlement upgrading.

The aim of providing affordable, reliable, sustainable, and modern energy for all requires an in-depth understanding of the issues that affect energy access and energy fuel choice, particularly as related to urban informal settlements or slums. Within unequal societies, such as South Africa, a reliance on technical solutions to address access and inequality is inadequate, leading to resistance and protest. Further, introduction of a technical solutionsuch as solar PV-to address energy access in urban informal settlements, is a complex process, and requires a systems thinking perspective. Using Community Based System Dynamics modelling, this paper therefore investigated the issues that affect energy fuel choice and energy access as related to the introduction of a renewable energy solution in Enkanini informal settlement. Different energy user groups were engaged in the identification of the factors that affect energy access and energy fuel choice; the relationships between these factors in order to improve future interventions; and development of causal loop diagrams to visualise the key feedback loops. The identified factors were economic and market related such as affordability, availability, and land ownership but also included a range of socio-political aspects. 17 feedback loops emerged, of which 13 were reinforcing loops, and 4 were balancing loops. The key feedback loops relate to community empowerment and representation, whilst participation in the political process and the quest for legitimacy through direct electricity connections were recognised as broader issues to be addressed.

Summary The rapid growth of urban informal settlements, or slums, poses a particular challenge for balancing developmental and environmental goals. In South Africa, high levels of inequality, poverty, and unemployment contribute to widespread migration. The influx of migrant workers to cities, however, is rarely matched with adequate housing and infrastructure, resulting in the formation and growth of urban informal settlements. Despite the persistence of the slum phenomenon, very few studies provide an in‐depth understanding of the metabolic processes that link these spaces, and informal economies, to the broader urban environment and economy. This article therefore utilized a multiscale integrated assessment of the societal and ecosystem metabolism approach to examine human activity and land use in Enkanini, an urban informal settlement in Stellenbosch, South Africa. The results highlight a number of issues to be addressed through spatial, developmental, and local economic policy, such as the need for improved transport linkages. The time‐use results show that Enkanini is a net provider of labor to the surrounding area. Further, geographical mapping indicates Enkanini as a small, but vibrant, informal economy, while being grossly underserviced in terms of water, waste, and sanitation infrastructure. Key implications are discussed in terms of the theoretical, methodological, societal, and policy impact of the study, including the need for city observatories that conduct regular data collection and analysis.
