Plants suitable for biomass production in a sustainable bioeconomy
Bioeconomy comprises the production of all goods that stem from bio-based, renewable raw materials. This contribution focuses on the production of biomass from crops cultivated as energy crops and on ecosystem services that go beyond the production function. Today, many industrial and energy crops are annuals that have been diverted from food and feed production. Tomorrow’s crops need to be more stress-tolerant and more water-, nutrient- and land-use efficient. They need to be able to provide ecosystem services, should become more diverse and should enable a multiple and integrated biomass use. Due to climate change, it is to be expected that the area of marginal agricultural land characterized by biophysical constraints, such as drought and salinity, will increase. Future biomass crops need to be able to handle such conditions and at the same time maintain or even increase the resilience of these areas. In many cases, these requirements can best be fulfilled by perennial biomass crop production systems, such as Miscanthus, cup plant, and wild plant mixtures. Such perennial systems can help avoid erosion, improve soil fertility and, especially in the case of wild plant mixtures, enhance biodiversity. Their production, and thus also their benefits, can be integrated at the landscape and farm level, for example, by cultivating them on biophysically or economically marginal agricultural land, including sub-optimally shaped or distant fields and ‘greening’ areas. In this way, biomass for a growing bioeconomy could be provided without compromising social-ecological requirements.
