Laura Riggi (researcher)

Laura Riggi
I am an agro-ecologist with 10 years’ experience investigating land-use impacts on arthropod communities and ecosystem services. My research focuses on the development of biodiversity-friendly agro-ecosystems. Specifically I investigate the impacts of land-use change and management practices on arthropod communities and ecosystem services from field to landscape scales by combining diverse methods (e.g. field & greenhouse experiments, molecular analyses, spatial modelling).


My research interests are to assess how landscapes and land-use practices impact biodiversity, and ecosystem services in agroecosystems and investigate practices that promote biodiversity, such as increasing crop diversity.

I have used large-scale field experiments and modelling to investigate how landscape composition impacts pests, pollinator, and natural enemy community and traits. At the field scale I am interested to assess how crop diversification practices, such as inter-cropping and organic fertilization (such as novel organic fertilizers from insect production), impact arthropod and microbial communities and yields. In particular, I am interested to better understand interactions across different compartments, such as above- and below-ground communities, to inform effective habitat management practices.

Currently I am leading a project funded by FORMAS, focussing on assessing the effects of strip-cropping on above and belowground communities and the services they provide. 

Outside of research I enjoy drawing and sharing on biodiveristy in agroecosystems via stories and illustrations.
