Adoption of common business practices lead to increased adoption of cookstoves: Study

A new study has found that adoption of common business practices like upgrading the supply chain, careful market analysis and discount can lead to increase purchase and adoption of improved cookstoves by 50 per cent in rural India.

The study was published in the 'Proceedings of the National Academy of Sciences'.

"Previous studies have found low demand for these cookstoves, however, our study found that when barriers to adopting the stoves were addressed, the demand was high," said Subhrendu Pattanayak, Oak Professor of Environmental and Energy Policy at Duke's Sanford, lead author of the study.

Three billion people still rely on traditional cookstoves that use solid fuels such as wood or coal. These stoves contribute to climate change through carbon emissions, deforestation and toxic air pollution, which contributes to poor health among users and their communities.

Improved cookstoves use either electricity or biomass as an energy source. Switching to them can deliver 'triple wins': better household health, better environmental health and reduced climate change emissions.

The adoption of improved cookstoves has been slow, however, likely because of constraints imposed by differences in markets, culture and geography.

The Duke researchers took a novel approach by implementing the study in three phases -- diagnose, design and test -- over a period of five years.

In the first phase, the researchers analysed existing research on improved cookstove adoption and looked at sales across different potential study communities, which provided insight into both demands- and supply-side barriers to adoption.

They found no common strategies for promoting changes in cooking behaviour but instead concluded the socio-economic case for adoption was influenced by local context. They then conducted focus groups in more than 100 households in 11 rural Indian communities, which allowed researchers to understand local cooking practices, perceptions of different stoves and preferences for stove features.

In the design phase, researchers worked with local organisations to implement eight small pilot programs in three different settings. This included small-scale testing of various supply chain issues such as marketing and home delivery, rebates and financing, and offers of electric and/or biomass cookstoves.

In the third phase, they conducted a field experiment to determine whether the combination of upgraded supply and demand promotion would lead to increased adoption of improved cookstoves. The field test included nearly 1,000 households in 97 geographically distinct villages in the Indian Himalayas.

The experiment showed that more than half of the intervention households bought an improved cookstove compared with zero purchases in the control villages.

The demand was very price-sensitive, and the largest rebate, 33 per cent of the retail price, led to the largest purchase rate, 74 per cent. In the areas that only had an upgraded supply chain and promotion without rebates, there was a 28 per cent increase in ownership of the improved cookstoves.

Households overwhelmingly preferred the electric stove over the biomass stove, by a factor of two to one. Respondents liked the lack of smoke, speed of cooking and portability and attractiveness of the stove.

However, this preference for electric stoves highlighted the lack of a steady source of electricity. In India, rural electrification rates have been rising rapidly, growing from 57 to 83 per cent between 2005 and 2015.

"Our work shows how energy access programs and projects can scale up and achieve success by understanding local demand and developing robust regional supply chains," said co-author Marc Jeuland, professor of public policy and global health at Sanford. (ANI)
