Rebound effects could offset more than half of avoided food loss and waste
- 2023

Journal article (peer-reviewed)abstract
- Reducing food loss and waste (FLW) could lessen the environmental impacts of food systems and improve food security. However, rebound effects-whereby efficiency improvements cause price decreases and consumption increases-may offset some avoided FLW. Here we model rebounds in food consumption under a scenario of costless FLW reduction. We project that consumption rebound could offset 53-71% of avoided FLW. Such rebounds would imply similar percentage reductions in environmental benefits (carbon emissions, land use, water use) and improvements in food security benefits (increased calorie availability), highlighting a tension between these two objectives. Evidence from energy systems suggests that indirect effects not included in our analysis could further increase rebounds. However, costs of reducing FLW would reduce rebounds. Rebound effects are therefore important to consider in efforts aimed at reducing FLW.Efficiency improvements that cause price decreases and consumption increases may offset the benefits of avoided food loss and waste (FLW), hindering progress towards SDG 12. Based on published income-group- and food-type-specific price elasticities of supply and demand, this study quantifies the direct rebound effects from large reductions in FLW of six types of food.

A systematic scoping review of the sustainability of vertical farming, plant-based alternatives, food delivery services and blockchain in food systems
- 2022
-
In: Nature Food. - : Springer Science and Business Media LLC. - 2662-1355. ; 3, s. 933-941
-
Journal article (peer-reviewed)abstract
- Food system technologies (FSTs) are being developed to accelerate the transformation towards sustainable food systems. Here we conducted a systematic scoping review that accounts for multiple dimensions of sustainability to describe the extent, range and nature of peer-reviewed literature that assesses the sustainability performance of four FSTs: plant-based alternatives, vertical farming, food deliveries and blockchain technology. Included literature had a dominant focus on environmental sustainability and less on public health and socio-economic sustainability. Gaps in the literature include empirical assessments on the sustainability of blockchain technology, plant-based seafood alternatives, public health consequences of food deliveries and socio-economic consequences of vertical farming. The development of a holistic sustainability assessment framework that demonstrates the impact of deploying FSTs is needed to guide investments in and the development of sustainable food innovation. Gaps in the literature include empirical sustainability assessments of blockchain technology and plant-based seafood alternatives, public health consequences of food deliveries and socio-economic consequences of vertical farming.

Food system development pathways for healthy, nature-positive and inclusive food systems
- 2021
-
In: Nature Food. - : Springer Science and Business Media LLC. - 2662-1355. ; 2:12, s. 928-934
-
Journal article (peer-reviewed)abstract
- Sustainable food systems require the integration of and alignment between recommendations for food and land use practices, as well as an understanding of the political economy context and identification of entry points for change. We propose a food systems transformation framework that takes these elements into account and links long-term goals with short-term measures and policies, ultimately guiding the decomposition of transformation pathways into concrete steps. Taking the transition to healthier and more sustainable diets as an example, we underscore the centrality of social inclusion to the food systems transformation debate. Addressing trade-offs between the environment, health and inclusion in the quest for sustainable food systems requires integrated and coherent policies. This Perspective proposes a food systems transformation framework that brings these elements together and enables the design of concrete development pathways for food sustainability.

Halting European Union soybean feed imports favours ruminants over pigs and poultry
- 2021
-
In: Nature Food. - : Springer Science and Business Media LLC. - 2662-1355. ; 2
-
Journal article (peer-reviewed)abstract
- The European Union relies on imports of soybean for protein-rich animal feeds. Scenarios of animal-source food supply in the EU under constraints relating to soybean production and imports for animal feed are assessed for effect on land use and human diets in the EU.The European Union (EU) livestock sector relies on imported soybean as a feed source, but feeding soybean to animals leads to a loss of macronutrients compared to direct human consumption, and soybean production is associated with deforestation. Here we show that 75-82% of current EU animal fat and protein production could be sustained without soybean imports while avoiding increased use of cropland for feed production within the EU. Reduced soybean feed exports, mainly from South America, would free up 11-14 million hectares outside the EU, but indirect land-use changes would increase demand for palm oil produced in southeast Asia. Avoiding imported soybean feeds would result in reduced EU pork and poultry production; increased plant-based food consumption would be required to maintain the supply of essential nutrients for human diets. Optimizing livestock production to overcome dependency on imported soybean feed can reduce cropland demand in deforestation-prone areas while supporting the nutritional requirements of EU diets-but will require progressive policies targeting all aspects of the food system.
