The sustainable consumption and production of animal-source foods (ASF) is at the centre of the debate for meeting several of the sustainable development goals. The tension in the debate is that animals provide essential macro- and micronutrients for humans, but also cause major environmental problems. Livestock currently use about 70% of all agricultural land (arable land and grassland). Expansion of livestock production, therefore, has been a main driver of the conversion of forests and native grasslands into agricultural land, resulting in a loss of biodiversity. The question is how we can secure or even optimize biodiversity within a circular food system.
The potential role of farm animals in the food system largely depends on how to keep the animals. Recently, several studies showed that farm animals reared under the circular paradigm can play a crucial role in feeding humanity. These farm animals then would not consume human-edible biomass, such as grains, but convert by-product from the food system and biomass from grasslands into valuable food, manure and other ecosystem services. In such a circular food systems interactions (trade-offs and synergies) can occur between food supply and biodiversity. Use of grassland for grazing, for example, has been reported to impair, but also to conserve and even enhance biodiversity, depending on the management intensity, site fertility, soil type, and other environmental factors. The use of grasslands, moreover, precludes alternative uses. Some grasslands, especially those that were once covered with forest, could benefit from being rewilded. As such there is an opportunity cost entailed in rearing livestock: not all biomass from grasslands can be considered 'free' for livestock production.

Wageningen University & Research
The chair group Animal Production Systems (APS) groups at Wageningen University & Research and Department of Terrestrial Ecology at the Netherlands Institute of Ecology (NIOO-KNAW) are looking for a PhD candidate within the project "Towards a circular food system". The APS group focusses on unravelling the complexity of concerns in livestock systems and exploring trade-offs and synergies of innovations regarding environmental impact, animal welfare, and economic viability, to design a more sustainable future. The Department of Terrestrial Ecology studies how interactions between organisms affect the composition and functioning of ecological communities, with the aim to improve sustainable management of terrestrial ecosystems.
