The Forum of the International HCH and Pesticides Association--a platform for international cooperation.

The unsustainable life cycle management of pesticides in the last 60 years has created large pesticide stockpiles. The two major working areas of the International HCH and Pesticide Association (IHPA; www.ihpa.info ) address a part of these legacies and are shortly introduced here: (1) The assessment and support of the management of the worlds single largest POPs stockpile: the globally dumped 4 to 7 million tonnes hexachlorocyclohexane (HCH) wastes from lindane production, and (2) the support for the management of the obsolete pesticides legacy in Eastern Europe, the Caucasus and Central Asia (EECCA) countries of ~240,000 t, leaving these pesticides in unregulated storages without adequate safety control being a huge risk to the environment and human health. The integrative approach IHPA takes-promoting international cooperation and the exchange of knowledge and experiences-is shortly explained. IHPA has developed various supporting tools for its work: the IHPA web page and newsletter informing on the threats and challenges, but also on the progresses of managing pesticide stockpiles; the joint GIZ-PAN-IHPA exhibition on awareness of the pesticide stockpile challenge; and the 'International HCH and Pesticides Forum' as most important tool to progress the integrative work and mission of IHPA. Finally, a summary of the 11th International HCH and Pesticides Forum held in Gabala, Azerbaijan is given which brought together more than 120 scientists, policy-makers, non-governmental and international organisations, industry and students from more than 40 countries to progress the obsolete pesticides and hazardous chemical waste challenge in EECCA countries. The event finished with adoption of 'Gabala Declaration', which aims to mobilise efforts of all stakeholders for prevention and elimination of POPs, obsolete pesticides, and hazardous chemical waste in the region.
