This document describes the AfroWeeds project, which aims to consolidate knowledge about weeds that affect rice production in Africa. Rice is a major crop on the continent but weed problems cause 28-89% yield losses. The project will create a centralized online knowledge base of Africa's major rice weed species, including an identification tool. It will also develop paper guides and networks to disseminate information to farmers, researchers and extension workers. This will help close knowledge gaps about weed identification, biology and management, improving rice productivity through better integrated weed control in African countries.

- 7. Relevance of the Action • Rice is one of the major cereals consumed in Africa • Rice production / increasing consumption • Rice prices / increasing • Africa is heavily dependent on the international market • Lowland rice production systems / 52% of the total area under rice in Sub-Saharan Africa
- 8. Relevance of the Action • Limited production / ineffective control of weeds (responsible to 28-89 % of yield losses) • Better productivity – effective weed control – effective adoption result
- 9. Specific problems • Integrated weed management / knowledge of weed biology and ecology • Extension services and researchers of National Agricultural Research Systems (NARS) or Universities / a lack of information on problem weeds – weeds identification – weeds biology – management practices
- 10. Relevance of the proposal • New science and technology framework – weed research – management in rice production • Centralised platform of information on the major weeds
- 11. The specific objectives • Consolidation of existing scientific knowledge for the weed species of irrigated and rain-fed lowland rice • Enhancing exploitation and dissemination of best weed management practices
- 13. Outputs and expected results • Established and consolidated networks at intra-ACP level • Fully functional website containing the knowledge base on the weed species • Computer tool for identification and information on rice weeds for Africa • Concise paper version of the knowledge base – information flow for the extension workers – disseminating scientific knowledge
