Perennials as Future Grain Crops : Opportunities and Challenges
- 2022

In: Frontiers in Plant Science. - : Frontiers Media SA. - 1664-462X. ; 13
-
Journal article (peer-reviewed)abstract
- Perennial grain crops could make a valuable addition to sustainable agriculture, potentially even as an alternative to their annual counterparts. The ability of perennials to grow year after year significantly reduces the number of agricultural inputs required, in terms of both planting and weed control, while reduced tillage improves soil health and on-farm biodiversity. Presently, perennial grain crops are not grown at large scale, mainly due to their early stages of domestication and current low yields. Narrowing the yield gap between perennial and annual grain crops will depend on characterizing differences in their life cycles, resource allocation, and reproductive strategies and understanding the trade-offs between annualism, perennialism, and yield. The genetic and biochemical pathways controlling plant growth, physiology, and senescence should be analyzed in perennial crop plants. This information could then be used to facilitate tailored genetic improvement of selected perennial grain crops to improve agronomic traits and enhance yield, while maintaining the benefits associated with perennialism.

Is the future of agriculture perennial? Imperatives and opportunities to reinvent agriculture by shifting from annual monocultures to perennial polycultures
- 2018

In: Global Sustainability. - : Cambridge University Press (CUP). - 2059-4798. ; 1, s. 1-18

Journal article (peer-reviewed)abstract
- Modern agriculture is associated with numerous environmental predicaments, such as land degradation, water pollution, and greenhouse gas emission. Socio-economically, it is characterized by a treadmill of technological change, increased mechanization, and economic consolidation, while depressing economic returns to farmers. A root cause is the dominance of annual plants cultivated in monocultures. Annual crops require the yearly clearing of vegetation resulting in soil erosion and other forms of ecosystem degradation. Monocultures are susceptible to agricultural pests and weeds. By contrast, perennial polycultures informed by natural ecosystems, promise more sustainable agroecosystems with the potential to also revitalize the economic foundation of farming and hence rural societies.

Sverige kan leda en revolution i jordbruket
- 2019
-
In: Svenska Dagbladet, SvD Opinion. - 1101-2412.
-
Journal article (other academic/artistic)abstract
- Sverige kan bli ledande i en radikal omställning av framtidens matproduktion. Genom forskning och utveckling av perenna livsmedelsgrödor kan vi aktivt främja en perenn revolution i jordbruket. Perenna grödor återkommer år efter år utan att behöva sås på nytt, skriver en rad forskare.
