Redesigning the European food system on the basis of circularity principles could bring environmental benefits for Europe and the world. Here we deploy a biophysical optimization model to explore the effects of adopting three circularity scenarios in the European Union (EU)27 + UK. We calculate a potential reduction of 71% in agricultural land use and 29% per capita in agricultural greenhouse gas emissions, while producing enough healthy food within a self-sufficient European food system. Under global food shortages, savings in agricultural land could be used to feed an additional 767 million people outside the EU (+149%), while reducing per capita greenhouse gas emissions by 38% but increasing overall emissions by 55% due to the increased population served. Transitioning the EU’s food system towards circularity implies sequential changes among all its components and has great potential to safeguard human and planetary health.

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan mengandung daun indigofera (Indigofera zollingeriana) terhadap respon fisologis dan hematologi kelinci Rex. Penelitian menggunakan 4 ekor kelinci Rex betina yang dibagi menjadi 2 perlakuan. P0 merupakan perlakuan tanpa mengandung daun indigofera, P1 merupakan perlakuan pakan mengandung 20 % daun indigofera. Variabel yang diamati dalam penelitian yaitu: laju respirasi, denyut jantung, suhu rektal, suhu kulit, kadar hemoglobin, jumlah eritrosit, nilai, jumlah leukosit, dan kadar glukosa. Data respon fisiologis didapatkan dari masing-masing 4 ekor kelinci di tiap perlakuan. Data respon fisiologis dianalisis menggunakan T-test, dan data hematologi didapatkan dari masing-masing dua ekor kelinci dari tiap perlakuan, dan data dianalisis secara deskriptif. Hasil penelitian menunjukkan pemberian daun indigofera tidak memberikan pengaruh pada respon fisiologis kelinci. Hematologi kelinci yang diberi pakan daun indigofera masih dalam batas normal. Kelompok diet non-indigofera memiliki hemoglobin 11,5; eritrosit 3,7 × 106/mm3; 37,7 %; leukosit 9,8 × 103/mm3 dan glukosa 77,5 mg/dL. Kelinci pada kelompok indigofera memiliki hemoglobin 12,2, jumlah eritrosit 4,15 × 106/mm3, 39,55 %, leukosit 12,9 × 103/mm3 dan glukosa 87,0 mg/dL. Berdasarkan hasil penelitian dapat disimpulkan bahwa daun indigofera dapat digunakan hingga level 20 % tanpa memberikan pengaruh negatif terhadap respon fisiologis dan hematologi kelinci Rex.

Applying specific circularity interventions to the food system may have environmental benefits. Using an iterative linear food system optimisation model (FOODSOM), we assess how changes in human diets, imports and exports, and the utilisation of waste streams impact land use and greenhouse gas emissions (GHG). After including these circularity principles, land use and GHG emissions were on average 40% and 68% lower than in the current food system, primarily driven by a reduction in production volumes and a shift towards feeding the domestic population. Shifting from the current diet to a circular diet decreased land use with 43% and GHG emissions with 52%. Allowing up to half of each nutrient in the human diet to be imported, while balancing imports with equal exports in terms of nitrogen, phosphorus and potassium, also decreased land use (up to 34%) and GHG emissions (up to 26%) compared to no imported food. Our findings show that circularity interventions should not be implemented mutually exclusively; by combining a circular diet with imported food and fully utilising waste streams, the lowest land use and GHG emissions can be realised.
