What role will low-tech play in tomorrow’s society?
- Low-tech is a new concept of progress and innovation that is more sustainable, robust, and economical in terms of materials and energy.
- It finds its origins in the technocritical movement of the 1970s, which saw the development of several players promoting low-tech practices and know-how.
- Research is increasingly interested in low-tech approaches: the CNRS has launched two calls for projects focusing on “frugal sciences”.
- With the aim of achieving carbon neutrality by 2050, low-tech could make it possible to reduce electricity consumption in electronics and household appliances by a factor of three.
Smartphones, connected speakers, tablets, computers, connected watches… High-tech devices are proliferating in our homes. The impact of this technological explosion on the planet is now well known. Only 1% of the rare earths used to manufacture these objects, such as indium or gallium, are recycled on a global scale. Not to mention the pollution caused by the massive use of data. Over the last ten years or so, the low-tech movement has been campaigning for a new definition of modernity and innovation, where we question our consumption and our habits.
“Useful, sustainable and accessible”
The concept of low-tech was once seen as an opposition to progress, a rejection of technology in favour of simple, home-made solutions. In reality, it’s part of a wider movement to reflect on our environmental impact, our needs and our ways of meeting them, which dates back to the 1970s. It’s not about going back to the candle, nor is it simply about promoting green industrial technologies or eco-designed objects. The Low-Tech Lab defines low technologies as “objects, systems, techniques, services, know-how, practices, lifestyles and ways of thinking that integrate technology according to three main principles”. These technologies must be useful and meet individual and collective needs.
“It’s a question of collectively reappropriating needs, asking ourselves together what is really useful and what isn’t,” explains Quentin Mateus, engineer and director of research at the Low-Tech Lab. They need to be accessible, free of copyright and as simple as possible so that they can be used by as many people as possible, they need to be locally produced, they need to be adaptable to the needs and resources of each context, and so on. Lastly, low-tech products must be sustainable, optimised to have the least possible ecological and social impact, and as robust as possible, like L’Increvable, a washing machine designed by designers and engineers to last 50 years and be easily repaired and updated by its owners.
Collective reflection and training
Low-tech involves a collective, democratic and participative process of reflection, decision-making and training. “You have to help people develop their skills, if they don’t have the ability to begin with, so you have to give them free plans and learning frameworks, so that they can be more autonomous in repairing and adapting the object to my needs and context”, explains the engineer. There really is no precise definition of low-tech, no label or specifications, but the concept, which is based on broad principles, can be applied to a wide range of areas: mobility, digital uses, housing, food, education, culture, etc.
Low-tech also has a social and political dimension. In 2019, the think-tank La Fabrique écologique published a note on these sober and resilient technologies, signed by a number of players in the movement, including Philippe Bihouix and Amandine Garnier of the Low-Tech Lab, as well as Bruno Tassin, director of research at the Ecole des Ponts ParisTech, and Marc Darras, chairman of the Centraliens “Ingénieur et Développement Durable” professional group.The note explains that “this approach is not just technological, but also systemic.It aims to challenge economic, organisational, social and cultural models”. So, it’s also about imagining new models of consumption, production, and governance. “It’s a mistake to simply want to replace high-tech with low-tech out of concern for the environment. It’s about questioning high-tech and its world”, says Quentin Mateus.
What role can scientific research play?
According to Martina Knoop, a physicist and director of the Mission pour les initiatives transverses et interdisciplinaires (MITI) at the CNRS, which has already put out two calls for research projects to promote “frugal sciences”, science and researchers have their rightful place in this process of questioning. “Low-tech approaches are frugal approaches. It’s about doing just as well with less investment in materials, energy, research time and so on,” she explains. To achieve this, researchers are looking at simpler processes, instruments and sensors that consume fewer natural resources. All disciplines are involved.
By way of example, one project selected by the CNRS is concerned with monitoring air pollution. Mélina Macouin, a researcher at the Geosciences and Environment Laboratory in Toulouse, is using plane tree bark as biosensors to analyse the presence of nanoparticles. The study is a blend of low-tech and participatory science, with Toulouse residents invited to put up garlands of plane tree bark in their homes. This approach to citizen science, which is often low-tech, is becoming increasingly popular, according to the director of MITI. “Doing better with less is an inherent part of research, in all our processes. It is sometimes more difficult and complex to invent a simpler, less energy-consuming process that performs just as well. Constraints can be a source of inventiveness and the basis of future innovations”, says the physicist.
What role will scientists play in a low-tech society? “If we are to put in place the conditions necessary for the development of a low-tech economy in all its dimensions, these new forms of research, which are also more distributed and more firmly rooted in each context, have their full role to play, and in the process a sense of purpose to rediscover. We need brainpower, collective intelligence and a high level of social, economic and technical engineering to dismantle what is no longer viable, to reallocate, to recompose appropriate sectors and a lacework of sociotechnical organisations. It will take time and human intelligence, but not necessarily a high data throughput”, argues Quentin Mateus.
Rethinking our industry
A low-tech society therefore requires us to rethink the way we practise science and technology, as well as the place of industry. For the Low-Tech Lab representative, it’s not a question of getting rid of the sector and our industrial fabric. Once again, we need to think in terms of needs.
In 2021, ADEME, the French Agency for Ecological Transition, has drawn up a scenario for a “frugal generation” to achieve carbon neutrality by 2050. This would include “respect for nature” and the establishment of a production system based on low-tech, “more robust and repairable by citizens”. It would involve cutting electricity consumption by a third for specific uses such as electronics and household appliances, switching to more extensive farming, significantly reducing mobility (by encouraging cycling, for example), relocating certain production processes and reducing demand for products and services by giving pride of place to the “economy of functionality and repair”. The overall demand for energy – electricity, heat, gas and petrol – would be halved compared to 2015. Greenhouse gas emissions would fall by 42 million tonnes of CO2 equivalent.
