The four-year project will help China to fulfill the requirements of the Stockholm Convention. The project aims to address endosulfan phase out by biological control and alternative technologies in cotton pest management in China. The project will achieve this project objective through demonstration of biological control andalternative technologies in pilot locations that will lead to subsequent complete phase-out of endosulfan in China through the implementation of a national replication programme prepared under this project. The project as outlined is structured with four components: Component 1 will strengthen institutional and management capacities to ensure efficient and effective project management; Component 2 will develop and demonstrate integrated technical models of biological control and alternative technologies; Component 3 covers thepreparation of a national replication programme and work plan, when implemented, will achieve complete 2 phase out of endosulfan in China; Component 4 supports the monitoring and evaluation of the project and dissemination of experience and lessons learned, something that is seen as useful for other developing countries dealing with the issue globally. In addition; project management capacity at national and the demonstration locations will be strengthened to achieve implementation effectiveness and efficiency.
