Unlocking Africa’s Bioeconomy: Sustainable Growth through Biodiversity and Innovation

Developing a bioeconomy in Africa presents a significant opportunity to drive nature-positive economic growth, leveraging the continent’s rich biodiversity and emerging innovations in sustainable technologies. Key to this vision is the potential to turn natural resources and waste materials into valuable products, creating jobs and addressing socio-economic challenges in the process. The water hyacinth, one of the world’s most invasive aquatic plants, is a case in point. Often clogging rivers and disrupting ecosystems, it is now being transformed into biogas, packaging materials, fertilizers, and even thermal insulation. This transformation reflects the broader goals of a bioeconomy, where nature is used sustainably to generate economic value.

One area of innovation is the use of mushroom mycelium (the root system of fungi) to create biodegradable composites. These mycelium-based materials, which are cultivated by feeding fungi on organic biomass like agricultural waste, offer an eco-friendly alternative to traditional building materials. Without requiring high-tech equipment, these materials can be grown anywhere, making them accessible and sustainable. They can replace plastic-based packaging, serve as insulation, and even be used for floor tiles and furniture. Importantly, they are being studied for their potential to create self-healing and self-growing structures, which could transform construction in Africa and beyond.

Such technologies exemplify the bioeconomy’s potential to merge biological processes with cutting-edge innovation. Ventures like this help to diversify value chains and bring sustainability to industries traditionally reliant on harmful processes. As young innovators across sub-Saharan Africa explore these possibilities, the bioeconomy offers a unique platform for youth-driven solutions to environmental and economic challenges. With 70% of the region’s population under 30, there is immense potential to tap into the creativity and resourcefulness of millions of young people, harnessing their ideas to reshape industries and unlock new economic opportunities.

At a global level, the G20 Initiative on the Bioeconomy, introduced by Brazil’s presidency, aims to position the bioeconomy as a catalyst for sustainable development. This initiative aligns with goals for social inclusion, climate action, and nature-positive growth. According to the World Bioeconomy Forum, the current global bioeconomy is valued at $4 trillion, and estimates suggest that it could grow to $30 trillion by 2050, signaling the massive potential for growth.

Africa’s bioeconomy can be broadly divided into three categories. First, there are products for which there is already a market, and Africa is a leading or unique supplier. Moringa, for example, is a tropical tree native to Africa whose seeds can be used as a natural coagulant for water purification. Moringa also has industrial potential in the production of biodiesel, fertilizer, and livestock feed. Similarly, wood processing, which benefits from Africa’s forests, could contribute billions to the economy if industrialized, potentially creating millions of jobs. However, single-species plantations must be managed carefully to avoid negative impacts on biodiversity.

Second, there are goods for which Africa has intrinsic competitiveness but lacks sufficient market demand. In Kenya and Rwanda, businesses are turning food waste into fertilizers and animal feed. Such ventures can position Africa as a green processing and export hub, helping pioneer sustainable industries. Additionally, there is untapped potential in wild African foods like South Africa’s buchu and rooibos or West Africa’s shea tree, all of which have global appeal in the health and wellness sectors.

Lastly, there are opportunities in bio-based innovation and technology. Mushroom-derived mycelium materials, for instance, have already gained popularity in Europe and the U.S. as alternatives to plastic and conventional building materials. In Africa, these mycelium composites could help address environmental problems while adding value to agricultural waste streams, providing a greener route for waste management, including plastics and other carbon-based materials.

Realizing the full potential of Africa’s bioeconomy, however, requires the integration of these efforts into national and regional economic plans. There is a need for more research, development, and innovation to ensure sustainable use of bio-resources. This also includes developing biodegradable biomaterials and avoiding harmful practices, like using essential food crops for biofuel production or engaging in mass monoculture, which could damage ecosystems.

Financial support is critical in scaling the bioeconomy. Both public and private sectors need to realign financial flows toward nature-positive outcomes, supporting the development of green industries. African countries must move quickly up the technological innovation curve to fully capitalize on the bioeconomy’s potential. This requires not only policy and regulatory reforms but also the attraction of investors who understand the economic and environmental opportunities within this sector. Achieving this will involve overcoming challenges such as global debt, technological gaps, and the impacts of climate change, all while fostering sustainable development and social inclusion across the continent.

James Irungu Mwangi, founder of Africa Climate Ventures and the Climate Action Platform – Africa, and Simon Zadek, co-chief executive of NatureFinance, highlight that scaling Africa’s bioeconomy will not only drive economic growth but also serve as a key tool in tackling climate change and promoting sustainable jobs.
