The risk reduction of pesticides and the reduction of highly toxic pesticides to promote food safety and sustainable development of crop production through implementation of the International Code of Conduct on the Distribution and Use of Pesticides and relevant international treaties is one of the main areas of FAO’s work. Improvement of regulatory pesticide management is key to implementation of the code of conduct. Delegates from 16 countries participated in this workshop on enhancement of regional collaboration in regulatory management of pesticides. It was noted that all countries had made progress in their efforts at regional harmonization. The workshop provided an opportunity to share expertise and resources among countries and to learn and assist each other in the process of making amendments to relevant regulations and legislation. The continual active collaboration among former TCP project countries (ASEAN) added value to the regional harmonization approaches. The workshop not only reviewed the progress made in the regulatory harmonization in member countries but also shared the outcomes of each country’s self assessment exercises and compiled the results in a system that allows for assessment in the level of regulatory harmonization in five areas by seven former TCP countries. The meeting consolidated the data requirements for different types of registration and produced an easy-to-use summary table of the requirements. A priority list of registration data requirements was developed by the participants, which can be used by the individual countries as a checklist for their own requirements and to measure their progress toward harmonization. Post-registration activities need strengthening in most countries. However, this is largely determined by the available resources. A priority list was developed to help countries with fewer resources to set-up activities that are within their means. The targets and indicators for regulatory harmonization and short/mid/long-term goals were updated and prioritized. Each country prepared a work plan for follow-up actions to achieve greater regulatory harmonization.
