The SAMSET Project hosted its second continuing professional development course at Victoria University in Kampala, Uganda from the 7th – 11th November 2016. The title of the course was “A Practitioner’s Insight into Urban Energy Planning, Implementation and Management”, and aimed to cover the issues that practitioners (such as urban planners, architects and municipal government officials) face when addressing urban energy management.
The first day of the course was focused on fieldwork in and around Kampala, aiming to give attendees experience of the issues facing Kampala in the urban energy and sustainable energy spheres today. The first part of the fieldwork focused on the central market district in Kampala, and involved a walking tour led by local partners through the market area and central business district of the city.

To say that the market area in Kampala is busy is an understatement. Passage through the area is only really possible on foot in some places, and even then only when avoiding the constant movement of goods and people through the narrow streets of the market district. The main roads in the area are extremely busy, with heavy goods vehicles mixing with matuba taxis and boda-bodas (motorcycle taxis) to create effective gridlock at some points in the day. The sustainable energy market, however, was on show in many areas, whether that be hole-in-the-wall shops selling small solar home systems, to street vendors selling improved cookstoves and cookstove liners. The challenges to urban transport were clear to see in the area, particularly how best to facilitate the movement of goods and people in the centre of the city, without stifling the bustling engine of economic growth that the central market district provides to the city.
The second phase of the CPD course fieldtrip involved a visit to a local landfill site on the outskirts of Kampala. This site processed a significant amount of the solid waste in the city, including from official waste management collection services and informal networks of waste collectors. The site also supports a network of informal waste pickers and processors, collecting items such as plastic waste for recycling. A recent initiative at the landfill has seen a PTFE processing facility constructed through collaboration with Chinese investors, although this site has not been without issues. In particular, while investment in the processing facility has created employment at the site, redistribution of profits from the facility has not occurred, with very little being reinvested in the site or community of waste pickers servicing it.

The issues facing solid waste management in large, primary cities such as Kampala are myriad, and the effects of this were plain to see in this phase of the trip. Collection and processing, as well as sustainability in operations, are both issues that need to be addressed by urban planners when considering municipal waste issues.
Innocent K. Agbelie and Simon Bawakyillenuo from the University of Ghana ISSER write on the Ghanaian government’s gas policy and renewables development. This article was originally posted at urbanafrica.com.
From 2012 to the beginning of 2016, the Government of Ghana has been stretched to the limit due to the existing power supply infrastructure’s inability to provide constant and reliable electricity for domestic and industrial activities. This has resulted in the acute electricity supply load shedding known as ‘Dumsor’.
Ghana’s electricity supply market currently has an estimated 10 to 15 percent year-on-year demand growth rate, underpinned by increasing domestic and industrial demand. Prominent among the actions taken by government to placate highly agitated power consumers is the expansion of thermal plant facilities, which are powered by gas imported from Nigeria and also from the Atuabo Gas plant in Jomoro District in the Western Region of Ghana. Since 2000 the share of thermal plants in the total national installed capacity has been on the rise, contrary to the country’s avowed green economic development pathway. This share (computed from the difference between the total national installed capacity and total hydropower installed capacity as reported by the Energy Commission,2014 and 2015) went up from 16.8% in 2000 to 31.8% and 44.1% in 2005 and 2014 respectively.
In contrast, the total installed new renewables’ capacity is a woeful 0.1% of the national total power installed capacity in 2014, while the share of hydro-power installed capacity declined from 83.2% in 2000 to 55.8% in 2014. The increasing share of thermal power generation sources will increase Ghana’s carbon emissions, accelerating climate change and the associated extreme events.
According to the Minister of Energy and Petroleum, the Government of Ghana wants to ensure that the nation becomes self-sufficient in its energy supply. Accordingly, government intends to increase the share of thermal generation capacity to 80% in the total national installed power generation capacity in the next 10 years. These thermal plants, according to the Minster, will be powered by the cheapest source of fuel: gas. This pronouncement sadly evokes lots more questions than answers in the minds of many, including: “What is the future of renewable energy development in the next decade as it is uncertain what the remaining 20% of the installed generation capacity will constitute?”, “What will be the effect of having 80% thermal plants on Ghana’s carbon footprint in the next decade and beyond?”, “Does a cheap fuel source necessarily guarantee a clean fuel source?”
These and many other questions should prompt a rethink in the nation’s quest to become self-sufficient in not just energy, but clean and sustainable energy in the next decade.
Taking into account government’s pronouncement of increasing thermal share to 80% in ten years’ time, the future of the already unachievable renewable energy target is even more questionable. The thermally oriented energy mix projections into the future calls into question the sustainable development and green economy agenda of the country, given that Ghana is signatory to many international conventions and protocols that incorporate sustainability issues.
According to estimates by Ghana’s Environmental Protection Agency, the country’s annual greenhouse gas emissions have been on the rise, growing from 10 Mt CO2e in 1991 to 34 Mt CO2e in 2012. The bulk contributors to these emissions are the Energy, Agriculture, Forestry and Other Land Use (AFOLU) sectors. The country’s Third National Communication Report to the UNFCCC highlights that Ghana’s emission rate has grown significantly over the past two decades and contributes 33.66 Mt CO2e to global GHG emissions. With a projection of thermal plants making up 80% of the energy mix in the next 10 years, Ghana’s emissions are bound to increase significantly in direct contrast to the Policy Programme area of minimizing GHG emissions as outlined in the 2013 Ghana National Climate Change Policy.
Cheap-fuel thermal plants appear rather costly to the national and global environment in the medium to long-term. A more sustainable approach is required through commitment to policy strategies coupled with political will on the part of leaders, to take bold decisions in order to drive the renewable energy agenda just like they are doing on the thermal agenda. The fact is, the formulation of policies by policy makers are inadequate for a sustainable energy transition if practical actions are not taken to implement them. Civil society groups, research and advocacy organisations also need to put pressure on government so that it accomplishes its pronounced targets for renewable energy generation.
Originally posted on The Conversation, Louise Tait from the University of Cape Town Energy Research Centre writes on sustainable urban planning and energy, and the SAMSET Project’s role in supporting sustainable energy development in developing world cities.
Africa is experiencing a massive flow of people into urban areas. This is happening in major urban centres such as Lagos, Accra and Dar es Salaam as well as in smaller and secondary cities. The pace at which this urban growth is happening inevitably puts strain on city authorities. The supply of services and developing infrastructure is vital for human and economic development.
But the evidence base to support forward planning remains scarce for most cities. In its absence, cities run the risk of infrastructural lock-ins to systems that are unable to accommodate their growth sustainably.
Cities with high concentrations of people and economic activities are major sites of energy demand. Africa contributes very little to global climate change today. But future growth must be managed sustainably. If the emissions of developing country cities increase similar to many western cities today, catastrophic climate change will be unavoidable.
The SAMSET project
Supporting African Municipalities in Sustainable Energy Transitions, or SAMSET, is a four-year project that commenced in 2013. Its aim was to address sustainable energy transitions in African cities. It provides practical planning and implementation support to municipalities to manage future energy planning in a sustainable manner.
The project involves six cities in Ghana, Uganda and South Africa. The cities were Ga East and Awutu Senya East in Ghana, Kasese and Jinja in Uganda and Cape Town and Polokwane in South Africa. Research and support organisations in each country and the UK were involved as well.
Secondary and smaller cities are the main focus for support. These cities are also experiencing massive social and economic expansions. But they typically have less capacity to cope. Despite their significance as current and future sites of energy demand, they receive much less research and funding focus.
Secondary cities such as Uganda’s Kasese traditionally lack the research or funding to make sustainable energy transitions.
Developing an evidence base to support planning
The first phase of the project involved developing an evidence base to support planning and future implementation of sustainable energy interventions. Locally relevant planning tools are essential. There are very few studies investigating and modelling the energy systems of African cities. South Africa is a notable exception.
An urban energy system refers to all the flows of different energy resources, such as petrol, diesel, electricity, wood and charcoal in a city. It records where resources are produced or imported into an area and where they are consumed in different sectors. Such information can help cities better understand which sectors are major consumers and identify inefficiencies. It also helps identify where opportunities for energy efficiency and new technologies may lie, especially those associated with improved economic and welfare effects.
Much of how we understand urban energy systems is based on cities in western and developed countries. But many cities in Africa challenge assumptions about economic development trajectories and spatial arrangements that may be implicit in energy modelling approaches which are based on developed country experiences.
SAMSET modelled the urban energy systems of each of these cities using the Long-range Energy Alternatives Planning model. It was developed by the Stockholm Environment Institute. This model records all energy consumption and production in each sector of an economy. For example the household, commercial, industrial and transport sectors are all recorded. It is a useful planning tool because it projects the growth of energy systems until 2030 under different scenarios. This helps cities understand the future impacts of different investment and planning decisions now.
For SAMSET, universities in each country undertook primary data collection on sectoral energy demand and supply. A baseline model and range of scenarios were then collaboratively developed with local research partners and municipalities.
The project aimed to develop an evidence base to serve as a tool for local decision-makers. Also for further collaborative energy strategy development and to prioritise the implementing of options for the next phases. The scenarios have therefore attempted the following:
Through stakeholder engagement, to take into account governance systems.
Existing infrastructural constraints and opportunities.
Aligning with other development imperatives.
Value of the process
The project has served to introduce to city and local planners the use of energy models. It also attempted to set up the foundation for future development of energy modelling exercises and its applications. Collaborating to collect data, discuss key energy issues, and identify interventions are highly valuable to local stakeholders.
The process was instrumental in generating an understanding of energy planning. For some of municipalities, this was the first time consideration has been given to energy as a municipal function.
The modelling process acts as a strategic entry point to build interest and support for the project with municipal stakeholders. It also provides a useful platform and tool to engage around long-term planning and the implications of different actions. An example is infrastructural lock-in to emissions and energy intensive growth paths.
Value of the outputs
SAMSET is making an important knowledge contribution to the dynamics of sustainable energy transitions in African cities. Such research is of course made difficult by the data scarcity typical at a sub-national level. But this is merely reflective of the lack of financial investment to date.
The local data collection processes in this project have been vital in building capacity and generating awareness around urban energy systems. Developing new data and building knowledge of urban energy transitions in the global south is critically important. It has had a strong focus on establishing a network of both north-south and south-south practitioners to support more work in this arena.
The modelling has had to account for several distinct characteristics. These include:
The informal economy
Own energy generation through diesel and gasoline generators
The high reliance on biomass
Variations in urban forms and issues such as suppressed demand for energy services.
This project has also made important methodological contributions to modelling urban energy systems in developing countries.
This blog is part of a series on the Energy and Sustainable Urban Development in Africa course , 17 – 21 November, 2014, University of Cape Town. For more details on the purpose of the course, see this blog.
Day four of the CPD was dedicated to the interlinked themes of urban planning and transport energy consumption, as well as introducing themes on policy planning for urban development.
The day began with two presentations from the technical and policy side of urban form and urban planning. Dr Nancy Odendaal, University of Cape Town began with an introduction on thinking about urban planning, covering the history of urban planning development in Sub-Saharan Africa, from colonial concepts of urban planning to modern considerations, such as dealing with urban sprawl. Urban planning was defined as methodology for societal development, re-imagining an urban region or wider territory, priorities for investment, conservation, infrastructure and land use. Dr Odendaal also made clear the fact that urban planning is not restricted to city planners, and planning occurs in all spheres, therefore it can be clearer to refer to the planning system, rather than planning activities. A different kind of urbanisation, that of modern development, requires a different kind of planning – 62% of the population of sub-Saharan Africa live in slums, and 60% work in the informal economy – 78% in Francophone countries. Informality is no longer the exception, yet city planners often still see informality as illegality.
Professor Ivan Turok from the Human Sciences Research Council continued this theme with a presentation on the current state of urban and urbanisations policies in Africa. A key assumption in planning is that the functional urban form is the foundation for everything else to be built upon, and dysfunctional urban forms perpetuate dysfunctional energy relationships. Despite a wealth of experience in the sector in the region (50 years of projects, 20-30 years of sectoral programmes, 5-10 years of cross-cutting urban policy development), the lack of shared experiences and cumulative learning has led to a lack of integrated strategies, which is a critical barrier for developing effective urbanisation policies. Some counter-examples exist in Ethiopia, with the Federal Urban Development Policy focusing on SME development and job creation for urban areas, and Morocco, where the Integrated Progressive Human Settlements program since 2001 has had a major impact on slum populations. A number of other African countries are developing urbanisation plans in the face of the urban energy challenge.

The afternoon sessions focused on transport policy and development in an urban context. Initially linking to the morning’s planning sessions through a brief introduction of the Voortrekker Road corridor upgrading in Cape Town, Herman Pienaar, head of Planning at the City of Johannesburg, presented on the Corridors of Freedom project, and more broadly an introduction to corridor-based transport planning in an urban context. Johannesburg is connecting key economic nodes in the city with bus rapid transit corridors, and in an effort to create system sustainability, is also encouraging mixed land-use planning and a network approach to transport planning in the city. With sustainability and liveability of the urban built form the key goals of this project, a combined whole-system focus is seen as the most effective way of achieving this.
Dr Lisa Kane, consultant and Honorary Research Associate at the Centre for Transport Studies, University of Cape Town, went on to present about challenges to transitioning to a lower energy and emissions transport sector through a broadly-focused presentation on transport energy use culture and perceptions, as well as policy momentum. A number of recommendations came from this presentation – for example, public road space for public transport as a policy, increasing vehicle occupancy to improve efficiency, challenging car culture as ‘inevitable’, and supporting civil interventions through the state. Some unexpected points also came from this presentation, for example that the emerging middle class and richer consumers are a valid policy focus, given the unsustainable energy practices endemic to this economic bracket (for example, single-occupancy private car use).
Finally on day four, Roland Hunter, consultant at Hunter van Ryneveld (Pty) Ltd and former Chief Financial Officer of the City of Johannesburg, presented on the relationship between transport and infrastructure in African cities. Transportation spending in Africa as a whole is three times higher as a proportion of gross city product than in Asian cities, approximately 21%. Despite this, some inappropriate solutions are still receiving large amounts of funding from national governments. For example in South Africa, 60% of national government transport subsidies go to the rail sector, whilst they carry only 17% of passengers. Minibus taxis carry 61% of passengers nationally, but receive 2.1% of total government subsidy. Fundamental points from this presentation are that spatial form is the determining long-term driver of transport usage and energy consumption, and transport policy should be as much about improving the patterns of transport demand to improve sustainability.
