36 months• Start October 2009
Relevance of the Action
• Rice is one of the major cereals consumed in Africa
• Rice production / increasing consumption
Evolution of rice consumption and production in SSA (million tonnes)
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
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
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
Relevance of the proposal
• New science and technology framework – weed research– management in rice production
• Centralised platform of information on the major weeds
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

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

We need your help!Please find attached the list of the weed species missing in our data base.
After going through the list, you can send us an email indicating which species you have in your country for which you will be able to provide pictures and may be herbarium specimens
