Summary

As part of the Ecophyto II+ plan, INRAE and Ifremer were entrusted with conducting a collective scientific expertise on the impact of phytopharmaceutical products on biodiversity and ecosystem services in 2020. The results, returned in May 2022, confirm that all types of terrestrial and aquatic environments, as well as most of the organisms within said environments are contaminated on every level with phytopharmaceutical products.

Contamination levels vary according to the distance to the areas of use of these mainly agricultural products, leading to direct and indirect impact on ecosystems, including decline in terrestrial and aquatic invertebrate populations and birds, as well as changes in ecosystem functions and services. Different levers help mitigate contamination and its impact, with varying effectiveness depending on their combination (regulations, conditions of use of products etc.)

This expertise identifies research needs, in particular to better understand dynamic phenomena in a context of multifold pressure exerted on the environment. This will involve characterizing and predicting effects, as well as improving risk assessment procedures for the use of phytopharmaceutical products.

This book is aimed at all actors and decision-makers concerned by the use of phytopharmaceutical products and involved in the legal, political, industrial or associative field, as well as in research or education.

Impacts on ecosystem functions
Innovations and future directions for the assessment of effects
4. Consequences for ecosystem services
Conceptual links between functions and services
Principal ecosystem services impacted
Innovations and future prospects regarding ecosystem services
5. Cross-cutting areas of concern or improvement
Issues related to the choice of substances
Accumulation phenomena
Reported improvements
Improvements made, and persistent difficulties on the scientific front
6. Interactions between science and regulation
Requirements and complexity of PPP regulations
Available scientific knowledge not being considered
Disconnection between pre-market and post-market assessment
Most frequently identified avenues for improvement

Conclusions
PPP contamination is known to affect all environments
The state of knowledge in the French overseas territories remains highly incomplete
PPPs contribute to the weakening of biodiversity
PPPs reduce the capacity to provide ecosystem services
Impacts are highly dependent on the methods and context of use
Instruments to partially mitigate the impacts
In non-agricultural areas, a redesign of management methods
The ambitious objectives of the PPP regulatory framework have not been fully met
The use of existing knowledge for regulatory purposes needs to be better organised
Taking better account of the complexity of exposures and effects
Linking the study of agricultural systems to that of ecosystems
