Landscape aesthetics in the Greifensee watershed

Stable yields in plant production are crucial for farm profitability and food security. Model simulations show that the yield stability of many summer crops could decline substantially due to climate change, while winter crops are significantly less affected.

Duckweed can efficiently produce protein-rich biomass on nutrient-rich waters, such as wastewater or liquid farmyard manure, while simultaneously binding nitrogen and phosphorus. This presents potential for modern circular economy systems.

Imports from abroad were incorporated into Switzerland’s farm-gate-budget-based agricultural nutrient budget calculation to expand it into a food-system budget. This allows assessment of self-sufficiency, nutrient use and circularity to be assessed in addition to nutrient surpluses.
