Cooking with electricity in Nepal

Posted on February 11, 2020April 16, 2023 by janet.crompton

PhD student Will Clements tells us how switching from cooking with biomass to cooking with electricity is saving time and saving lives in Nepal.

Sustainable Development Goal 7 calls for affordable reliable access to modern energy. However, around 3 billion people still use biomass for cooking. Smoky kitchens – indoor air pollution due to biomass cooking emissions – account for the premature deaths of around 4 million people every year. The burden of firewood collection almost always falls on women and girls, who must often travel long distances exposed to the risk of physical and sexual violence. The gravity of the problem is clear.

Electric cooking is a safe, clean alternative which reduces greenhouse gas emissions and frees up time so that women and girls can work, study and spend more time doing what they want.

In Nepal, many off-grid rural communities are powered by micro-hydropower (MHP) mini-grids, which are capable of providing electricity to hundreds or thousands of households, but often operate close to full capacity at peak times and are subject to brownouts and blackouts.

A project to investigate electric cooking in Nepali mini-grids was implemented in the summer of 2018 by a collaboration between Kathmandu Alternative Power and Energy Group (KAPEG), People Energy and Environment Development Association (PEEDA) and the University of Bristol in a rural village called Simli in Western Nepal. Data on what, when and how ten families cooked was recorded for a month, at first with their wood-burning stoves, and then with electric hobs after they had received training on how to use them.

When cooked with firewood, a typical meal of dal and rice required an average of 12 kWh of energy for five people, which is around the energy consumption of a typical kettle if used continuously for six hours! On the other hand, when cooked on the induction hobs this figure was just 0.5 kWh, around a third of the energy consumed when you have a hot shower for 10 minutes.

However, even at this high efficiency, there was insufficient spare power in the mini-grid for all the participants to cook at the same time, so they experienced power cuts which led to undercooked food and hungry families.

Many participants reverted to their wood stoves when the electricity supply failed them, and this with only ten of 450 households in the village trying to cook with electricity. The project highlighted the key challenge – how can hundreds of families cook with electricity on mini-grids with limited power?

In April 2019, the £39.8 million DFID funded Modern Energy Cooking Services (MECS) programme launched. The MECS Challenge Fund supported the Nepal and Bristol collaboration to investigate off-grid MHP cooking in Nepal further.

The project expands on the previous project by refining data collection methods to obtain high quality data on both Nepali cooking practices and MHP behaviour, understanding and assessing the potential and effect of electric cooking on Nepali MHP mini-grids, and using the collected data to investigate how batteries could be used to enable the cooking load to be averaged throughout the day so that many more families can cook with electricity on limited power grids.

MHP differs greatly from solar PV and wind power in that it produces constant power throughout the day and night, providing an unexplored prospect for electric cooking. Furthermore, this 24/7 nature of MHP means that there is a lot of unused energy generated during the night and off-peak periods which could be used for cooking, if it could be stored. Therefore, battery-powered cooking is at the forefront of this project.

Collected data will be used to facilitate a design methodology for a battery electric cooking system for future projects, evaluating size, location and distribution of storage, as well as required changes to the mini-grid infrastructure.

Furthermore, a battery cooking laboratory is being set up in the PEEDA office in Kathmandu to investigate the technical challenges of cooking Nepali meals from batteries.

The baseline phase – where participants’ usual cooking is recorded for two weeks – is already complete and preparations for the transition phase are underway where electric stoves are given to participants and they are trained on how to cook with them.

We will be heading to Kathmandu to help with the preparations, and the team will shortly begin the next phase in Tari, Solukhumbu, Eastern Nepal.

The project will continue the journey towards enabling widespread adoption of electric cooking in Nepali MHP mini-grids, the wider Nepali national grid and grids of all sizes across the world.

Localising the Sustainable Development Goals for Bristol

Posted on February 20, 2018April 4, 2023 by janet.crompton

In 2015 the 17 UN Sustainable Development Goals (SDGs) were ratified by 193 of the UN member nations. These goals set ambitious targets to address worldwide issues of sustainable development, such as social inequality, responsible and inclusive economic development and environmental protection. They were created for everyone, everywhere and have been described as ‘the closest thing the world has to a strategy’.

Who will be responsible for ensuring we achieve these goals and how will they be achieved?
In the realm of international agreements, national governments have traditionally been responsible for local implementation. But a combination of profound global demographic shifts and a sense that national governments are increasingly incapable of tackling complex global challenges due to domestic political wrangling has given rise to a global movement to place cities at the heart of efforts to tackle both local and global challenges. This movement, which is coalescing around a constellation of city-to-city networks (such as ICLEI, C40 and the Global Parliament of Mayors), is now grappling with the challenge of ‘localising the SDGs’. How can we usefully translate this global agenda into local practice in a way that meaningfully transforms lives?

This is the question we are working to answer through a new University of Bristol funded project on Localising the SDGs for Bristol, in partnership with the Bristol Green Capital Partnership (BGCP), Bristol City Council and Overseas Development Institute (ODI).

Bristol is a city of great wealth and has strong environmental credentials as the former European Green Capital in 2015. The city is also home to a vibrant cluster of ‘green economy’ companies and environmental charities. However, Bristol also faces many challenges. Homelessness is twice the national average; nearly 16% of Bristolians live in England’s 10% most deprived areas; and Bristol health outcomes are worse than the national averages for many indicators (e.g. life expectancy, suicide, childhood obesity, smoking).

These are precisely the kinds of challenges that the Sustainable Development Goals are encouraging us to confront and tackle by 2030. Importantly, ‘sustainability’ isn’t just about the environment; it is also about building a prosperous and inclusive economy that leaves no one behind. Inclusion, equality and opportunity are essential to achieve sustainability.

Our research seeks to identify and support mechanisms for embedding the SDGs in local planning and governance processes by engaging with a wide range of stakeholders in the city.

Bristol City Council, a pivotal stakeholder is currently working to bring partners together for a new One City Plan. This Plan seeks to use the collective power of Bristol’s key organisations to achieve a bigger impact by supporting partners, organisations and citizens to help solve key city challenges and improve the lives of Bristolians across the city. The core themes behind this plan align with the SDGs and it provides a great opportunity for Bristol to lead nationally and internationally on the SDGs. As this plan comes together we aim to input insights from other cities around the world that are also working to implement the SDGs.

Los Angeles Mayor Eric Garcetti committing to the SDGs for LA

To that end Allan Macleod, the Cabot Institute SDGs Research & Engagement Associate, recently attended the Global Ambition–Local Action Conference hosted by the Occidental College in Los Angeles. The conference focused on what cities can and are doing to address the SDGs and how they can mobilise data and resources to further their work. It was a very informative experience, but was it was also inspiring to see how Bristol compares to some of the largest and most important Global Cities. It was clear that Bristol has developed a solid foundation for SDG localisation and has a real opportunity to become global leader in implementing the SDGs. In doing so the city will both confront the need to develop a more inclusive and sustainable local economy while contributing to global efforts to tackle transboundary problems together with other cities.

This is a particularly exciting time to be working collaboratively on implementing the SDGs in Bristol as the city will be hosting two major conferences in 2018: the Data for International Development Festival at the end of March and the Global Parliament of Mayors Annual Summit in October. Both these events provide Bristol with an opportunity to showcase its leadership and demonstrate its credentials as an important international city that is working to improve the lives of all its citizens.

Why cities are crucibles for sustainable development efforts (but so hard to get right)

Posted on April 25, 2017April 5, 2023 by janet.crompton

Fox, S. & Goodfellow, T. (2016) Cities and Development, Second Edition. Routledge.

Sustainable Development Goal 11 outlines a global ambition to ‘make cities and human settlements inclusive, safe, resilient and sustainable’. It is arguably one of the most important of the 17 recently agreed Goals, but we’re unlikely to reach it in most parts of the world by 2030.

The importance of Goal 11 stems from global demographic trends. As Figure 1 illustrates, over 50% of the world’s population already lives in towns and cities, and that percentage is set to rise to 66% by 2050. In fact, nearly all projected population growth between now and 2050 is expected to be absorbed in towns and cities, and the vast majority of this growth will happen in Africa and Asia (see Figure 2).

These trends mean that when it comes to eliminating poverty and hunger, improving health and education services, ensuring universal access to clean water and adequate sanitation, promoting economic growth with decent employment opportunities, and creating ‘responsible consumption and production patterns’ (and achieving many other goals) urban centres are on the front line by default.

But cities are complex political arenas prone to the kinds of conflicts that can thwart ambitious visions for transformative development.

To appreciate just how difficult it can be to achieve seemingly obvious and desirable improvements in cities, it is useful to examine some practical challenges. Consider the goal of ensuring access to clean, affordable water for all (Goal 6, Target 1; Goal 11 Target 1). In cities across Africa and Asia, a significant share of households live in informal settlements that lack piped water infrastructure. As a result, most residents rely on water provided by private vendors who sell water by the bucketful from tanker trunks or standpipes that they control. Perversely, the poor often end up paying a significant premium for their water on the open market, while more fortunate residents who are connected to municipal infrastructure pay far less. This perpetuates inequality, both between socioeconomic groups and between men and women (as women generally bear the burden of water collection in such contexts), and it also means that there are groups of people with fairly strong incentives to resist infrastructure investments: the water vendors. And these vendors sometimes take aggressive steps to protect their captive markets and thwart infrastructure development.

A similar dynamic is often at play when it comes to upgrading informal settlements more generally. In many cities poorer households do not have formal (i.e. legally binding) tenure security but rather pay some form of rent to a third party in return for protection against eviction. This form of ‘land racketeering’ is often undertaken by the very politicians and bureaucrats who should be seeking to improve citizens’ lives.

In other words, urban underdevelopment creates profitable opportunities for some, which in turn creates interest groups opposed to change.

But even rich cities, with well-developed physical infrastructure and formal tenure arrangements, often suffer from political gridlock that impedes progress. Consider the city of Bristol in the UK. Bristol was recently voted the best place to live in the UK, yet the city also suffers from dangerous levels of air pollution, which is linked directly to debilitating levels of traffic congestion in the city.

While Bristol’s transport woes have long been recognized, it has proven fiendishly difficult to tackle the underlying problem: a lack of metropolitan-scale transport planning and investment integrated with land use plans. This is due to a legacy of ‘horizontal fragmentation’ and ‘vertical dependence’.

Figure 3. Map of Greater Bristol with council boundaries

Horizontal fragmentation refers to the fact that Greater Bristol—i.e. the functional area of the city as defined by daily commuter behaviour—is home to over 1 million people spread across four different local government areas, each with its own budget, council, transport planning processes, etc. As Figure 3 clearly shows, the local government boundaries (in red) carve up this functional urban region into four artificial parts). Indeed, in some places, such as north Bristol, local government boundaries run straight through clearly contiguous built-up areas (represented as grey). The challenge of coordinating planning and investment across four councils is compounded by the fact that in the past any major infrastructure investment needed to be approved and funded by the UK central government (i.e. the problem of vertical dependence). This support is not necessarily forthcoming. An ambitious plan tabled around the turn of the millennium to integrate city transport with a tram network, and make the whole system more inclusive for low income residents, was rejected by central government. This is a prime example of how political challenges in wealthy countries impede development progress.

In sum, there are significant political obstacles to progress in poor cities and rich cities alike. But this doesn’t mean that progress is impossible. In fact, recognising and understanding these political complexities is helpful in identifying effective courses of action, whether as citizens, activists or policymakers. I doubt we will fulfil the aspirations of SDG 11 in a convincing manner by 2030, but I am hopeful that progress can be made if we approach the challenge with our eyes wide open to the political dynamics that could undermine our efforts.
