Understanding the impact of agri-environment schemes on emerging infectious diseases in pollinators

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

This project will: (i) substantially enhance our understanding of the landscape of RNA viruses, both emerging and non-emerging, in wild and managed pollinators, (ii) determine the dynamics, directionality, and overall epidemiology of emerging diseases in wild and managed pollinators and test whether these are affected by agri-environment schemes, (iii) elucidate the mechanisms behind disease transmission and determine how they impact transmission at semi-field scales, and consequently (iv) provide suggestions for management of agri-environment schemes that are designed to benefit wild and commercial pollinator populations, in order to minimize the threat of emerging disease. In addition to the academic community (see 'academic beneficiaries'), we have identified 5 sectors that will benefit from this work. We aim for rapid and high impact of our results on policy for pollinator management, enhancing the UK's biodiversity and agri-economy.

1) national and international policy-makers, regulators & government
Emerging disease is a significant focus of attention for national and EU-level policy makers, e.g., the designation of notifiable diseases and requirement for health certificates prior to international bee transport. Policy makers and government will benefit from this work as it will fill a major hole in our understanding of whether and how viruses emerge across the commercial-wild pollinator divide, as well as the impact of agri-environmental schemes on this emergence. This is critical during the ongoing development and implementation in the UK of the reformed Common Agricultural Policy and the National Pollinator Strategies, as well as the development of new agri-environment schemes. Consequently, our outputs will enable the development of evidence-based policy to protect the ecosystem service of pollination.

2) land management and seed producers
Agri-environment schemes aim to improve ecosystem services and conservation. To achieve this for pollinators, seed producers that provide nectar and pollen seed mixtures and land managers need to understand how these schemes affect not only pollinator abundance and diversity, but also how they affect pollinator health. Our results will allow seed producers to optimize the seed mixtures they sell and will allow land managers to improve pollination services and pollinator conservation.

3) conservation agencies
Numerous conservation NGOs in the UK (e.g., Bumblebee Conservation Trust, Buglife, Bee Guardian Foundation, RSPB) and globally (IUCN) require a deeper understanding of the factors driving wild pollinator declines in order to devise both policy and on-the-ground management. Our research will provide the information necessary to enable such agencies to manage both floral interventions and commercial honeybees, to maximise the health of wild pollinator populations

4) commercial honeybee managers
Currently, over 40,000 honeybee colonies are managed commercially in the UK, for pollination services and honey production. Our research results will enable commercial producers to minimize both the impacts of emerging diseases spreading from managed honeybees into wild bees, and the likelihood of acquiring such diseases from the wild, which will therefore increase the value and efficiency of these important commercial pollinators.

5) publics
From specialist interest groups, such as Beekeeping Associations, through to schools and adult communities, there is a deep and abiding interest in bees and their health. Results from our work will be of broad interest to this range of public communities, enabling them to understand how science is trying to address the global problem of bee decline. Moreover, our results will have a direct and immediate role in conserving pollinators, as urban gardens are currently important refuges for these beneficial insects due to their forage availability. Our research results may directly benefit the design of bee-friendly gardening schemes
