Understanding the roles of pollinators and herbivores in sustainable urban agroecosystems
Lead Supervisor: Dr Jill Edmondson, Animal and Plant Sciences
Co-supervisor(s): Dr Stuart Campbell, Animal and Plant Sciences; Prof James Hitchmough, Department of Landscape
Deadline: Monday 26th March 2018
The human population will rise to 9 billion by 2050, posing a severe challenge to global food production. This challenge will be exacerbated by the rapid pace of urbanisation. Worldwide, 25-30% of the urban population participates in food production, and urban agriculture is recognised as an increasingly important contributor to food security. It is therefore critical to understand the biotic and abiotic factors that limit or sustain urban agriculture.
Two of the primary factors influencing fruit and vegetable yield are herbivory and pollination – however we know relatively little about how these interact in agroecosystems. Plant species diversity in urban greenspaces may be important for supporting insect diversity, but our understanding of the relative importance of pollinators and herbivores in urban food production remains poor. This studentship will explore how pollinators and herbivores influence urban agricultural productivity, and what factors underlie variation in herbivory and pollination in these systems.
This project will focus on allotment growers, as allotments are the primary areas of own-grown food production in urban Europe. Measure Your Harvest (MYHarvest: https://myharvest.org.uk) is a citizen science project at the University of Sheffield which is analysing own-grown fruit and vegetable production across the UK. The extensive MYHarvest dataset will include plot level crop diversity, soil quality, and management techniques. This studentship will use the MYHarvest network to address three fundamental questions that are at the core of understanding the biotic factors that sustain urban agricultural productivity:
- How does pollinator abundance and visitation influence allotment food production?
- What is the diversity, abundance and impact of herbivorous insects in allotments?
- How does allotment structure and proximity of natural areas influence pollination and herbivory?
This studentship will combine observational field studies and experimental manipulations. This project will require extensive fieldwork across the UK. The student will gain a diverse skillset in agricultural and sustainability science, plant ecology, entomology, community ecology, landscape ecology and GIS. Public engagement and knowledge exchange will be integral to this research The studentship will contribute original research into processes underlying productivity in urban agriculture with the potential to deliver impact in the UK and beyond.
The student will work in collaboration with an interdisciplinary team of leading researchers in sustainable development, plant-insect interactions and landscape management.
