A global survey addressing sustainability of pollen monitoring
Abstract
Background: Contemporary airborne pollen records underpin environmental health warnings, yet how pollen monitoring networks are sustained is poorly understood. This study investigated by whom and how pollen monitoring sites across the globe are managed and funded. Methods: Coordinators listed in the Worldwide Map of Pollen Monitoring Stations were invited to complete a digital questionnaire designed to survey the people and organisations involved, types, and duration of funding sources, as well as uses, purpose, and sharing of pollen information. Quantitative data were analysed by descriptive statistics and open text responses were examined by qualitative thematic analysis. Results: Eighty-four of 241 (35%) coordinators from 37 countries responded. Universities (42%) and hospitals/health services (29%) were most commonly responsible for monitoring. Most sites involved employees (87%) in pollen monitoring, of whom many were part-time (41%) or casual (11%), as well as students (29%) and volunteers (6%). Pollen monitoring was additional to core duties for over one-third of sites (35%), and 25% reported pollen monitoring was an in-kind contribution. Whilst funding for pollen monitoring was often sourced from government agencies (33%), government research grants (24%), or non-government grants (8%), 92% reported more than 1 funding source, and 99% reported dependence on “partnerships or grants requiring co-contributions”, indicating a complex resourcing structure, of short duration (median 3 years). Common reasons why airborne pollen was monitored included clinical allergy, population environmental health, aerobiology and forecasting. Climate change, research, and social duty were also referenced. Conclusions: Aerobiological monitoring is currently sustained by complex, insecure, and insufficient resourcing, as well as reliance on volunteerism. There are multiple direct, health-related, and other important uses of aerobiology data, that are aligned to multiple dimensions of sustainability. Evidence from this study can be used to inform the design of strategies to sustain the generation of aerobiology data.
