This document contains the report of, and the paper presented at, the FAO Regional Workshop on the Elaboration of National Plans of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing - Southern and East Africa Subregion, held at Kariba, Zimbabwe, from 24 to 28 November 2003. The purpose of the Workshop was to assist countries in the southern and eastern Africa region to develop capacity so that they would be better placed to elaborate national plans of action to prevent, deter and eliminate illegal, unreported and unregulated fishing (NPOAs-IUU). The Workshop addressed the International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing (IPOA-IUU) in detail and the Technical Guideline that had been developed to support the implementation of the IPOA-IUU; two case studies; decision-making about IUU fishing and skills development through identification of key issues relating to the NPOA-IUU, the vehicle through which the IPOA-IUU will be implemented by countries. Working groups were formed to encourage maximum participation. A review of regional fishery issues was discussed including ways of improving collaboration and identifying regional priorities. The document prepared by Ms J. Swan entitled "National plans to combat illegal, unreported and unregulated fishing: models for coastal and small-island developing states" was funded through FishCode Programme component projects GCP/INT/849/USA ("Support for the Implementation of the International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing") with Trust Fund support from the Government of the United States of America, and GCP/INT/823/JPN ("Responsible Fisheries for Small Island Developing States (SIDS)") with Trust Fund support from the Government of Japan.
