A comprehensive national implementation plan, prepared in 2010, identifies stocks of POPs and presents a strategy for managing them, taking account of potential economic and social impacts. A substantial effort will be needed to achieve the plan’s objectives, as large quantities of pesticides and PCBs are in storage or use, and significant amounts of dioxins and furans are released to the environment. Colombia is receiving support from GEF and the UN Development Programme to develop its capacity for managing the disposal of PCBs. The pesticide glyphosate has been used to eradicate coca and poppy crops used to produce illegal drugs, although questions have been raised about its effectiveness and its health and environmental impacts.
