After the positive experience of expanding domestic production to the maximum in order to safeguard the food supply in the Second World War, greater importance has been attached to crop planning and storage for crisis situations in Switzerland than in neighbouring countries. The emergence of operational research meant that systems for the sole purpose of optimising calorie and nutrient supply became an integral component of crisis preparedness. Today’s international debate on food security, on the other hand, focuses on the dynamic price trends and price fluctuations of food, an aspect which has not as yet been incorporated into Swiss preventative strategy. However, the most recent food crises show that, especially for Switzerland, nominal supply failures are becoming increasing less likely than cardinal (i.e. fluid) supply constraints, in which price rises could become a supply problem for parts of the population. In order to gear Swiss nutritional planning to such crisis situations as well, price tre nds need to be included as a key variable in crisis planning.
A hoeing and spot-spraying device enables huge savings in the use of plant protection products. Although costs are higher than for conventional plant protection devices, motivated farm managers give this innovative technology genuine prospects for the future.
Thanks to their unique landscapes, the 15 regional nature parks, the majority of which are located in the (pre-)Alps and in the Jura Arc, feature as tourist attractions. But do the parks also provide economic value-added for local agriculture?
To balance their nutrient cycles, Swiss farms export surplus farmyard manure to farms with free uptake capacities or to composting and anaerobic digestion facilities. Between 2015 and 2020 the volumes of organic manure and recycled fertilisers transported rose significantly, with a consequent increase in transport costs.
