Food waste in primary production is rarely recorded – yet this data is key to devising effective reduction strategies throughout the entire value-added chain. This analysis evaluates existing measurement methods with the focus on vegetables. Around 37% of edible food is wasted every year in Switzerland. To address this issue, the Federal Council adopted the…

Designation of regional nature parks in Switzerland significantly boosts the adoption of direct payment schemes aimed at promoting biodiversity conservation (agri-environment schemes, AES), particularly in regions with relatively more intensive farming and low prior uptake of such schemes. Although both regional nature parks and agri-environment schemes (AES) aim to conserve biodiversity, the interaction between these…

If we systematically reduce inefficiencies in the food system—such as the heavy use of cropland-based feed, concentrate feed for cattle, and avoidable food waste—we can achieve much higher self-sufficiency while lowering environmental impacts.

The use of vegetable fibre can reduce plant-protection product residues by up to 80% in white musts, with a more limited effect in red musts.. The method can be applied in cellar, as a complement to the responsible use of products in the vineyard.
