Economic benefits of pollination to global food systems - Evidence and knowledge gaps

Lead Research Organisation: University of Reading
Department Name: Sch of Agriculture Policy and Dev

Abstract

Pollination by bees and other animals is crucial to the production of 75% of the worlds crops, including many that are widely traded around the world, such as coffee, cocoa and rapseeed. By increasing crop production, pollinators help ensure the functioning of many global food systems. However, human activity within those food systems often has negative effects on pollinators, decreasing stocks of "pollinator natural capital" (populations of animals that provide pollination services) and disrupting the flow of pollination services to crops and other beneficial plants. This has resulted in farmers losing out on millions of $ in production because their yields are limited by insufficient pollination.

Concerns over pollinator declines have been growing among national and global policy makers with high profile case studies such as the IPBES pollinator and global assessments, the UK's Dasgupta Review and the EU's INCA accounting report, all highlighting the need to value pollinator natural capital and pollination services for accounting and decision making. To date, much of the work on valuing pollination services has only focused on the value of the service itself to farmers and their immediate buyers (e.g. supermarkets), often focusing heavily on developed, temperate nations. As such, we know very little about i) global stocks of pollinators, ii) the relationship between stocks and pollination services or iii) the relative risks that different countries or actors within the global food system face from pollinator losses.

Our project will address these issues by synthesising published academic literature, globally available economic data and new critical analyses to produce: i) a detailed outline of the benefits of pollinators to food systems, ii) an evaluation of the importance of pollination to globalised food systems and risks of economically significant pollinator losses, iii) review methods for quantifying and mapping pollinator natural capital, iv) comprehensive guide to the existing methods and knowledge on the value of pollination, and v) a review of the methods and data needs for better evaluating the impacts of pollination to the whole food system.

In addition to two high quality academic publications, we will also collaborate with an experienced scientific artist to produce accessible materials for policy and businesses. Although the importance of pollination has been discussed in international (e.g IPBES) and UK policy (e.g. the Dasgupta review), and in natural capital research (e.g. VNN's state of natural capital report), it is rarely actually valued in a manner useful for decision making and accounting. By taking a whole food system approach and integrating both ecological and economic risks, our work will build on the information from the IPBES pollinators report and the Dasgupta review to produce the most comprehensive appraisal of the value of pollination available anywhere globally. Our work will help policymakers, academics and business to address challenges in measuring and valuing pollinators and pollination across the whole food system, identify parts of the world that are at high risks for pollinator losses, and highlight.

Description The research synthesised a wide range of literature and datasets on the economic benefits of pollinators. It highlighted four key findings that can be developed into further study:

1. Pollinators are important to the whole food system.
Although research has focused heavily on the role of pollination in food production, the whole range of actors across the system are affected by pollinator populations and can in turn affect pollination services through direct pressures on their populations or by driving pressures and responses.

2. Pollinators are key to global crop trade. Using global crop trade data we identified that on average, ~18% of national crop production is dependent upon pollination. We developed a simple means to classify countries by their degree of pollinator vulnerability to local or global pollinator losses.

3. Measuring pollinator natural capital requires further development of methods. Measuring pollinator natural capital in a spatially explicit manner is important to decision making. However models for doing so are lacking accessibility and SEEA accounting frameworks do not properly represent the value of pollination. To develop the necessary ecological-economic models of pollination services and the associated accounting framework, it will be essential to expand core research into pollinator ecology and sustain long-term pollinator monitoring efforts.

4. Valuation of pollination services over emphasises the links to producers. Although all actors in the food system can benefit from and affect pollinators, existing valuation methods and research overwhelmingly focus on the role of producers as drivers of change and recipients of benefits. As the value of pollination alone may not be sufficient to justify management actions, developing a more integrated method to value pollination services across the food system and in tandem with other ecosystem services will be important to properly inform management decision trade-offs.
Exploitation Route The project synthesis report (available online at https://www.ukri.org/publications/reports-of-the-economics-of-biodiversity-synthesis-projects/) outlines a number of research priorities for future ecological, modelling and economic research, including the identification of key pollinators, deeper research into the vulnerabilities of countries to pollinator losses and new methods to value pollination services to different actors. The project should also generate further discussion on how to better integrate wider biodiversity into food system and natural capital research.

Description The findings of this study have been presented to a group of civil servants from across government departments on 19/11/22 and are being refined into a number of scientific publications and further research projects designed to expand upon the key findings and address the research gaps identified. They have also been developed into a simple infographic to effectively communicate the role of pollinator to different actors within the food system.

Results and Impact At the request of DEFRA, we presneted an overview of the economic impacts of pollinators and their key reserach needs to a group of ~15 civil servants from various departments. This led to enquiries for more information from several, including the Home Office, DEFRA and the Treasury.

Results and Impact At the invitation of the UNEP-WCMC I presented an overview of work on capturing opollinators in National Ecosystem Assessments, drawing on various examples of the work undertaken in several UK projects and how to replicate similar work, or highlight the data needs to achieve similar outomes. Following this, there were requests from the Grenadian and Bosnia & Herzegovinan National Ecosystem Assessment teams for more information and advice on how to intograte pollinators into their assessments.
