"This publication provides information drawn from all regions to assist countries in replacing HHPs with ecosystem-based approaches to pesticide and crop management – replacing chemicals with biology. It draws together previously published and new material in a form that is accessible for policy- and decision-makers at the national and international level, as well as providing practical guidance at the farm and farm-support level. It also points out that use, and phasing out, of HHPs must be seen in the context not only of human health and environmental impacts and costs, but also in the context of food security, poverty reduction, and climate change."
