Reducing the reliance of traditional fuels in informal settlements

The pilot of a community kitchen in Portee-Rokupa, Freetown, Sierra Leone

There is political controversary around the total population of Freetown, Sierra Leone. The 2021 mid-term Population and Housing census noted a significant decrease in Freetown’s population which has subsequently been challenged by the mayor and other leading stakeholders. Statistics vary from 600,000 to 1.35million. Regardless, it is estimated that 36% of the city’s population live within densely populated informal settlements scattered across Freetown’s eastern peninsula. These communities, not too dissimilar to other low-income settlements across the city, and indeed other densely populated urban centres, are often located in geographically vulnerable areas and prone to increased hazards, risks and disasters.

It is in the informal settlement of Portee Rokupa where researchers from the University of Bristol have been working since 2021 (Figure 1). The ESRC funded ‘Beyond the Networked City’ project (grant number:  ES/T007656/1) is a collaboration between the University of Bristol, Loughborough University, Sierra Leone Urban Research Centre (SLURC), Makerere University, and the University of Cape Town that seeks to further understand urban service delivery of key infrastructure such as water, sanitation and energy in Freetown and Kampala. In close partnership with SLURC, over 360 households in Portee Rokupa were surveyed on their energy services such as electricity and cooking.

In Portee Rokupa, like most of these communities, their residents, mainly women and young girls, carry out the daily task of cooking. Cooking, whether for personal consumption or income generating purposes, is usually prepared using traditional biomass fuels such as charcoal with basic, inefficient metal stoves called coal pots (Figure 2). The use of traditional coal pot stoves are contributors to air pollution and environmental degradation affecting health of users and local forest cover.

Working closely with the residents and community actors in Portee Rokupa, there is an overwhelming desire to transition to cleaner cooking solutions, but there are challenges around accessibility, availability, finance, and imposed knowledge that hinders the sustainable uptake of ‘clean’ cookstoves. Whilst trying to further understand what could be done to improve their cooking service delivery, the idea for a communal cooking space, which offers a range of cooking technologies, to be used on a pay-as-you basis, was both desirable and aspirational for the community.

SLURC project managed the community kitchen project whilst also facilitating community dialogue to ensure that residents themselves were part of the design and construction, and management of the kitchen. They also fostered new and existing partnerships with key stakeholders including the Government Technical Institute (GTI), the Electricity Generation and Transmission Company (EGTC), and Afrigas, a national LPG supplier. What started as ad-hoc discussions around the need to improve cooking service delivery within informal settlements, turned into the creation of the Platform for Energy Safety, innovation, and Access Consortium (PESIA), a call to action for stakeholders to further understand the cooking needs of residents living in informal settlements.

To ensure long-term sustainability of the kitchen, community members were selected to become community Energy Champions and were trained by the above stakeholders on the use, maintenance, finance and safety of different cooking technologies that would enable them to provide tailored support in the community kitchen as well as broader advice around energy choices within the community. The community were involved at every stage of the project from kitchen design, choice of location, selection of preferred stoves and fuels as well as overall kitchen management. For example, because Portee Rokupa is predominantly a fishing community, the desire for larger stoves and ovens that would help smoke, preserve and process fish was something residents regularly communicated. The community kitchen does not only provide access to improved cooking facilities, but also serves as a hub for broader community interaction, something that is of importance to the community.

So, what has the Community Kitchen achieved? Since it’s official launch in May 2024 (Figure 4), the pilot has received significant attention within Freetown, especially on social media channels and within local news outlets. Management of the kitchen has been fully handed over to the community and energy champions who have elected a chairwoman and a chairman who will oversee the use of the kitchen and be responsible for financial accountability. Residents of Portee Rokupa are now regularly using the kitchen facilities, not only for their mealtime cooking, but for community events such as parties and weddings, and local entrepreneurs are using the kitchen for productive uses such as food preparation, fish smoking and soap making.

The broader impact of this initiative extends beyond the immediate benefits of access to cleaner, more efficient cooking solutions. The kitchen is now an official vendor of Afrigas bottles, bringing a consistent supply of LPG to the community for the first time. Community buy-in, consistent dialogue, co-creation of kitchen design and the training of energy champions has fostered a sense of ownership and responsibility, encouraging them to advocate for and implement sustainable practices within their communities. This grassroots approach has also extended into other informal communities such as Susan’s Bay and Dwazark where energy champions are spreading their knowledge to ensure households are more aware of different cooking options available rather than solely relying on traditional ways of cooking. The Portee-Rokupa community kitchen was a pilot initiative driven by a community desire to have access to alternative cooking services. It is now forging its way as a beacon of knowledge, empowerment and sustainability. It demonstrates how targeted training and community engagement can drive significant changes, paving the way for a more sustainable and resilient future for all. As these Energy Champions continue their work, they are not just transforming kitchens; they are transforming lives and building a brighter, greener future for their communities.

Indoor air pollution: The ‘killer in the kitchen’

Approximately 3 billion people around the world rely on biomass fuels such as wood, charcoal and animal dung which they burn on open fires and using inefficient stoves to meet their daily cooking needs.

Relying on these types of fuels and cooking technologies is a major contributor to indoor air pollution and has serious negative health impacts, including acute respiratory illnesses, pneumonia, strokes, cataracts, heart disease and cancer.

The World Health Organization estimates that indoor air pollution causes nearly 4 million premature deaths annually worldwide – more than the deaths caused by malaria and tuberculosis combined. This led the World Health Organization to label household air pollution “The Killer in the Kitchen”.

As illustrated on the map below, most deaths from indoor air pollution occur in low- and middle-income countries across Africa and Asia. Women and children are disproportionately exposed to the risks of indoor air pollution as they typically spend the most time cooking.

Replacing open fires and inefficient stoves with modern, cleaner solutions is essential to reduce indoor air pollution and personal exposure to emissions. However, research suggests that only significant reductions in exposure can tangibly reduce negative health impacts.
The Clean Cooking Alliance, established in 2010, has focused mainly on the dissemination of improved cookstoves (ICS) – wood-burning or charcoal stoves designed to be much more efficient than more traditional models – with some success.
Randomised control trials of sole use of ICS have shown reductions in pneumonia and the duration of respiratory infections in children. However, other studies, including some funded by the Alliance, have shown that ICS have not performed well enough in the field to sufficiently reduce indoor air pollution to lessen health risks such as pneumonia and heart disease.
Alternative fuels such as liquid petroleum gas (LPG), biogas and ethanol present other options for cooking with LPG already prevalent in many countries across the world.
LPG is clean-burning and produces much less carbon dioxide than burning biomass but is still a fossil fuel.
Biogas is a clean, renewable fuel made from organic waste, and ethanol is a clean biofuel made from a variety of feedstocks.

Electric cooking, once seen as a pipe dream for developing countries, is becoming more feasible and affordable due to improvements and reductions in costs of technologies like solar panels and batteries.

Improved cookstoves, alternative fuels and electric cooking have been gaining traction but there is still a long way to go to solving the deadly problem of indoor air pollution.
