Among the key findings are:
- Sub-Saharan Africa could at best contribute between 30% and 90% of long-term alternative aviation fuel demand in the form of RSB-compliant aviation biofuel produced from energy crops on approximately 84 million hectares of prime and good quality land and another 157 million hectares of moderately suitable land.
- This assumption holds that ALL energy crops on suitable land in sub-Saharan Africa would be reserved for the exclusive production of biofuels for aviation.
- The highest greenhouse gas (GHG) savings are typically achieved by perennial crops. To incentivise farmers to invest in the cultivation of such crops, the aviation industry and fuel suppliers should sign long-term off-take agreements to mitigate the risks related to their production.
- Annual energy crops could be planted on degraded land (such as the rehabilitation of mining land) and could replace other industrial crops in decline. An example would be replacing tobacco crops for the cigarette industry with Solaris tobacco which is a tested feedstock for biofuel.
- Because shipping feedstock long distances could reduce the GHG savings, the finished product should ideally be processed locally to develop a local biofuel value chain and industry.
QUOTES
Tjasa Bole-Rentel, WWF’s Bioenergy Programme Manager:
Ambitious targets are being set for biofuels around the world, both for land transportation and aviation, without a good understanding of how much we can produce sustainably. Such estimates are not possible without looking at the bigger picture of land availability and its agro-ecologic suitability for the production of energy crops in the context of all competing land uses for food, feed and nature conservation. This study sheds some light on what is realistically possible in terms of biofuel production in sub-Saharan Africa without compromising the region’s food security or critical ecosystems, so that we can set realistic targets and provide the right incentives to maximise the opportunities and minimise the risks of large scale biofuel production.
Rolf Hogan, Executive Director, Roundtable on Sustainable Biomaterials
As the aviation industry looks to ensure its long-term sustainability and comply with climate mitigation measures, the question of where these feedstocks and fuels are going to come from is becoming increasingly relevant. The industry needs to know that it can procure alternative aviation fuels that can demonstrate real greenhouse gas emission reductions and that don’t negatively impact on social and environmental sustainability. This report, supported by Boeing, proves that sub-Saharan Africa can play a major role in decarbonising the aviation sector, and that this can be done really sustainably and without impacting food security, land rights, water rights, conservation areas and more. There is a huge opportunity for responsible and sustainable economic growth on the continent to support the long-term viability of the global aviation industry. It shows that the potential is there in Africa and, with the right investments and incentives, that potential can become a game-changing reality.
Dr Sylvia Tramberend, International Institute for Applied Systems Analysis
The transition to a low-carbon economy with biomass as one of its energy sources will intensify the energy-agriculture linkage and add a new dimension to agricultural systems, heighten resource competition in the food system, and may provide new opportunities for rural communities. As food, feed and energy feedstock markets integrate more closely, both challenges and opportunities arise. Increasing biofuel feedstock production in sub-Saharan Africa, while at the same time meeting food demand targets and strictly following sustainability principles, faces a high degree of complexity. Integrated system analysis such as this helps unpack those complexities and will hopefully contribute to a better informed debate and policy development on the topic.
