Official bodies are posing a great attention toward the achievement of the holistic investigation of pesticides risk assessment. This implies a reliable assessment of the risk associated to pesticides use, in order to reduce their impact on the total environment. Focusing only on source (including dose) reduction would be rather limitant if the goal is to ameliorate the agriculture footprint. It is now accepted that simply decreasing the amounts of pesticides applied onto crops is not necessarily connected to a decrease in the risk to non-target species and water bodies supply. In fact, a reliable and accurate risk assessment must take into account environmental factors together with the specific pesticide chemical properties. In this framework, it is noteworthy to notice that EC has adopted the Commission Directive 2019/782 establishing Harmonised Risk Indicators to estimate trends in the risks from pesticide use.

Consequently, this session focuses on risks and advantages in risk assessment including the use of models and integrated practices, spatial scale and multi-stress situations, as well as the connection to international policies.
