ServiceGrass: Effects of organic farming on private and public ecosystem services and grassland multifunctionality
Context
Ecosystem services are the basis to secure human well-being. Grassland is known to potentially deliver an outstandingly high number of different ecosystem services to society. Sustainable agriculture must deliver not only private ecosystem services such as market goods but also many public ecosystem services, i.e. non-market goods and services such as recreation and carbon storage. Agricultural intensification usually increases private ecosystem services but impairs the delivery of many public services. As organic farming has the potential to decrease negative environmental impacts of intensive food and feed production, it might be able to sustain the provision of both private and public ecosystem services. However, this has never been assessed comprehensively for grasslands, although these constitute the largest share of organically managed land in Switzerland but also worldwide.
Project aims
The overall aim of the project is to assess and explain effects of organic grassland farming on several ecosystem services and their simultaneous provisioning, i.e. ecosystem service multifunctionality. Therefore, we will measure and compare the ability of Swiss organic and conventional grasslands to deliver different ecosystem services in relation to plot-scale grassland management. We also aim at upscaling the impact of grassland management on ecosystem services from plots to entire farms by using the Swiss Farm Accountancy Data Network. Using this database will also enable us to assess the economic dimensions of ecosystem services delivery by the two farming systems. Outcomes of the project will reveal strengths and weaknesses of organic and conventional farming in delivering private and public ecosystem services and help to improve grassland farming for a sustainable future. Results will be communicated to different stakeholder groups and society through many different outreach activities.
SoilServiceGrass
Due to the high relevance of soils, their biodiversity and functioning, for grassland-based ecosystem services, the pancivis Foundation Liechtenstein funded an additional one-year project focussing on soil processes and soil microbial diversity. We will assess microbial abundances and diversity as well as root biomass together with Martin Hartmann (ETH Zürich). These analyses will help to evaluate the effects of land use intensification and farming systems on belowground ecosystem properties and processes. This will allow for a particularly comprehensive assessment of the mechanistic impact of organic versus conventional farming on ecosystem services from grasslands.
