Th5_AFROweeds and Weedsbook: Online and Offline Weed Identification and Management Support for Better-informed Agricultural Change Agents

  1. 1. AFROweeds and Weedsbook: Online and Offline Weed Identification and Management Support for Better-informed Agricultural Change Agents R. Kabanyoro, J. Rodenburg, T. Le Bourgeois, P. Grard, A. Carara, R. Irakiza, D. Makokha, I. Dzomeku, T. Chiconela, I. Malombe, S. Sarra, F. Ekeleme, P. Marnotte Donor: EU - ACP Sciences & Technology Programme Coordinating centers: CIRAD & Afr icaRice
  2. 2. Justification from weed identification to weed management • • • • • • Weeds: major constraint to rice production across systems and regions Yield loss despite control 15-23%; Economic annual loss SSA: $1.5 billion Effective weed management requires informed actors and knowledge on weed species This requires accessible support tools, information sources and exchange platforms Increased use of internet, smartphones and tables enhances such access Opportunity and need for electronic tools and an online network

  13. 13. AFROweeds electronic weed identification tool • Available online at www.afroweeds.org/idao • Available offline when installed from a CD-ROM • Available offline on an electronic tablet when downloaded as an available as application • In the future, application on a smartphone
  14. 14. Testing the AFROweeds tool online and offline field try-outs • First test: online version using iPAD with 3G data SIM card • Second test: offline version (App) using iPAD with preinstalled AFROweeds App
  15. 15. Testing the AFROweeds tool online and offline field try-outs Fig. 1. Online version: average time 7 minutes and 6 seconds; success rate: 44%
  16. 16. Testing the AFROweeds tool online and offline field try-outs Fig. 2. Offline version (App): average time 5 minutes; success rate: 75%
  17. 17. Testing the AFROweeds tool online and offline field try-outs • Identifications failure causes: o Species was not yet included in the database o Lack of detailed character states (e.g. on leaf morphology, the bract length, bulbs) o Insufficient coverage of withinspecies character variations (e.g. flower color) o The user made an unnoticed early mistake in the selection procedure o Suboptimal 3G network coverage in the field • More practice will success rate and identification time increase decrease

  21. 21. Weedsbook The African Weed Science Network Key comments gathered: •Weedsbook allows sharing of information and can be used for training and communication •Helps professionals to update themselves on new developments and to generate new ideas •Creates new opportunities for collaboration between scientists and extension staff •Durability of the network should be ascertained •Weedsbook may boost weed science in Africa by attracting young students and scientists; need to grow (more members)
  22. 22. Conclusions better informed actors, better weed management AFROweeds tool … •… is not/never finished: it can/will be expanded with more species, more characters, more (rice) growing environments … •… will be made available for iPhone and Android systems and expected to replace field guides in book form … Weedsbook network … … is a useful platform for professionals and students to interact, learn, share, enhance their work or studies … … needs more members … … will continue as the African Weed Science Network AFROweeds tool and the online network Weedsbook •Mutually reinforce each other •Contribute to better informed actors, and therefore better weed management
