Laura Riggi (Post-doc)

Laura Riggi
I am a doctor in agro-ecology with 7 years of experience in ecosystem and landscape scale management, agro-environmental issues and conservation research and outreach. I have a strong background on agro-ecology and landscape ecology. Outside of academia, I manage the Bugs for Life charity, which aims to promote access to sustainable food and feed.

Presentation

Agricultural intensification has increased crop yields, but has also negatively influenced the flow of ecosystem services provided by beneficial organisms that support production. Management of ecological services needs to be effectively combined with external inputs such as insecticides and fertilizers to enhance and stabilize yields. This requires an understanding of factors that regulate the numbers of beneficial and pest organisms at the field and landscape scale.

Using widespread crops as model systems I am interested to investigate how local and landscape management influence ecosystem services (pollination and biological control) as well as pest density and resistance to pesticide.

At the landscape scale my work has focused on how land-use intensification impacts natural enemies and pollinators communities and diversity. Another aspect of my research investigates whether field scale management, in particular agricultural fertilization and diversification, could be managed to strengthen ecosystem services.

Research

Current Projects:

Red Clover project (2018 - 2020): Investigate the impact of mass flowering crops on pollinator communities and bumblebee pathogens.

Broad Bean project (2020 - 2021): Consequences of floral herbivory by Bruchus on pollination services in faba beans.
