Switzerland defined its climate-change adaptation strategy in March 2012, in a framework document from the Federal Council that describes approaches to be adopted by each sector of the economy. A first set of areas for action in agriculture had been identified in the 2011 Climate Strategy for Agriculture, and a revised strategy is expected to be published in the course of 2023 to strengthen these elements and link them to climate mitigation efforts.
Two successive action plans set out specific adaptation measures for each sector. The first of these covered 2014-19 and had 63 sectoral and cross-sectoral measures. The second, released in 2020 for 2020-25, has 75 measures, including 46 from the previous plan.2 These documents clarify what actions to undertake at federal, cantonal and communal levels, and lay out international collaboration channels to support climate adaptation. Some measures target agriculture specifically, while others have indirect implications in related domains (water management, biodiversity, human health, animal welfare).
Adaptation measures for agriculture, as defined in the successive adaptation plans, are organised around the following axes: (1) adapting products, production systems, and production practices; (2) improving knowledge of adaptation possibilities; and (3) mitigating weather-related risks for production and prices. Work started with the following action tracks:
optimised use of plants and suitable animal breeds, including pest management
enhanced use of land and water resources
data development for operations adapted to production sites
extension of monitoring and early-warning systems
analysis of opportunities to support private risk-management
Complementary actions with respect to water, soil, biodiversity, and human health can help agricultural adaptation. Examples in the domain of water management are determining water needs better, reviewing water-protection plans and management-planning tools, and developing improved drought-prediction systems. The current action plan includes soil-protection measures that link to carbon-sequestration objectives through a mapping of the state of Switzerland’s soils. Some measures related to biodiversity protection include the restoration of peatlands and creating areas with shade (including on agricultural land). Measures related to human health include protecting workers from high exposure to extreme heat, ultraviolet radiation, and other extreme events. For animal health, measures are planned to monitor and mitigate heat stress, as well as research on the emergence of new pests and diseases.
The Pilot Programme for Adaptation to Climate Change is an illustration of current federal efforts to support the uptake of these measures by funding specific projects that test adaptation actions. The first phase of the programme in 2013-17 funded 31 projects across Switzerland in the domains of water management, prevention of natural disasters, ecosystems and land-use management, urban development, and research. The second phase in 2018-20 funded 50 projects to analyse dairy-herd stress, ground-water management and reservoirs for irrigation, and agricultural development planning.
Other federal programmes also indirectly support adaptation efforts in agriculture. The Agri-food Quality and Sustainability Programme aims to increase the value-added and environmental and socioeconomic sustainability of agricultural production. The programme funds up to half the costs related to a selected innovative project. Similarly, the Sustainable Resource Management Programme (provision of Art. 77a under AgricA) covers up to 80% of the cost of investments in optimising the use of resources such as water, fertilisers, phytosanitary products, animal feed and drugs, and energy.
Adaptation strategies are also supported through public research activities. Agroscope’s 2022-25 research programme conducts several activities to develop new plant production and animal husbandry systems, and and animal varieties better adapted to the changing climate. This includes research on resource-efficient and site-adapted cultivation methods and production systems for field crops and special crops; new crop-breeding research based on genomic and phenotypic methods; and research on management and production practices. The climate adaptation plans also include knowledge-development activities that focus on regional climate-change scenarios for Switzerland, new hydrological data and scenarios for water policy, research on hail forecasting, and broader risk assessment at national and regional levels.
