This document discusses 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 significant yield losses. The project will create a centralized online knowledge base and identification tools about rice weeds in Africa. It will also disseminate best management practices through extension workers. Participating countries include Benin, Senegal, Mali, Burkina Faso, Cote d'Ivoire, Ghana, Nigeria, Chad, Niger, Guinea, Kenya, Tanzania, Uganda, Mozambique and Madagascar. The expected outputs are an established network, a functional website with the knowledge base, a computer identification tool,
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
