Most frequently identified avenues for improvement

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
