Food production systems in Europe rely largely on chemical pesticides to maintain crop
yields. However, pesticides can have significant negative effects on the environment,
particularly on biodiversity. For instance, the use of pesticides in farming practices can lead to
runoff of these substances into rivers, lakes and groundwater. If pesticide levels exceed critical
thresholds, individually or as mixtures, they affect ecological processes and make ecosystems
less diverse and less resistant to disturbances.1 Besides, pesticides are intrinsically harmful to
living organisms2 not only to targeted pests but also to pollinators such as bees and
butterflies.3 The decrease in pollinators, partly due to pesticides,4 raises concerns regarding the
sustainability of agriculture.5 Although there is a downward trend in the use and risk of chemical
pesticides including the more hazardous ones, this decrease has not yet resulted in reduced
pesticide levels in surface waters6 and soils.7 Furthermore, there are significant declines in
insect populations and on insectivorous birds. In addition, the health risks associated with
pesticide exposure are multi-faceted.
