A monitoring system for preventive control of Desert Locust in West Africa

  1. 1. A monitoring system for preventive control of Desert Locust in West Africa<br />Vincent Bonnal, SaïdLagnaoui, Thomas Dolley,<br />Jean-Philippe TONNEAU, Michel Lecoq, Jean-Michel Vassal<br />
  2. 2. The Desert Locust and invasions<br />Solitariy and gregarious phases<br />The choice of the Preventive Control Strategy <br />Scientific basis<br />Organization<br />Improvement measures<br /> The monitoring system<br />Place in the preventive control strategy<br />Development and implementation<br />What else ?<br />The vicious circle of locust control<br />
  3. 3. “and when it was morning, the east wind brought the locusts” <br />Exodus 10:13<br />“and the shapes of the locusts were like unto horses prepared unto battle”Revelation 9:7<br />“all thy trees and fruit of thy land shall the locust consume”<br />Deuteronomy 28:42<br />Photo Hans Brédo<br />
  4. 4. Alternance between invasion and recessionperiod<br />Invasion<br />Recession<br />Solitarious<br />Gregarious<br />
  5. 5. Desert Locust<br />Previous plagues: 1987-89 / 2003-2005<br />1 billion US $; 40 M ha sprayed<br />
  6. 6. Migrations<br />Bands <br />July - September<br />Swarms <br />August - October<br />Bands <br />March - May<br />Swarms <br />April - July<br />
  7. 7. S-W Asia<br />Western Region <br />Central Region <br />Current organisation<br />Rome<br />FAO (Locust Group)<br />Tehran<br />Algiers<br />Cairo<br />Gregarious areas<br />National locust units<br />
  8. 8. Organization of the Preventive control strategy<br />National<br /><ul><li>Development of independent national control units for Desert Locust
  9. 9. Survey and early warning by national control units
  10. 10. ecological conditions, presence of locust populations in the potential breeding areas
  11. 11. Early reaction
  12. 12. preventive control of the first gregarizing locust populations by national control units</li></ul>Regional<br /><ul><li>Emergency plans in case of outbreaks
  13. 13. Management of help at the regional level
  14. 14. Regional commissions / FAO : (RO, RC, ASW)
  15. 15. Organisation and coordination of control at the regional level
  16. 16. Common surveys, training and formation
  17. 17. Desert Locust Control Committee (DLCC) / FAO
  18. 18. All affected countries (including « front line » countries) and donors
  19. 19. Define the best control strategy
  20. 20. FAO : Desert Locust Information Service : Locust Watch
  21. 21. E-Locust-2 (Transmission of locusts data from survey teams to FAO) / RAMSES
  22. 22. Emergency plans in case of invasion (FAO)
  23. 23. Regional and international level, emergency funds, calls to international community</li></ul>International<br />
  24. 24. An application integrated to EMPRES-RO program : (Emergency Prevention System for western region)<br /><ul><li>The EMPRES strategy :
  25. 25. containing the problem at an early stage,
  26. 26. getting a permanent mobilization of national surveillance and control systems,
  27. 27. performing a coordination at the regional level on a consistent set of countries (western region)
  28. 28. centralizing the information and analysing the locust situation in DLIS (FAO Central)</li></li></ul><li>National LocustsUnits<br />Looking for locusts :<br />a permanent survey<br />Detection of locust populations at the earliest stage of gregarization <br />
  29. 29. National locust units<br />Preventive control on small areas according to locust population level<br />
  30. 30. The monitoring system : <br />At the regional level, development of a monitoring tool to check national units’ abilities to implement preventive control of locusts<br />
  31. 31. The monitoring system :a classical client / server architecture<br />Web server & data baseCLCPRO - Algiers<br />Data stored and managed at CLCPRO<br />
  32. 32. The monitoring system : a simple interface<br />1- dynamic menu, depending on the level of user rights<br />2- data added with a button<br />3- effective search tool<br />4- data display as a sortable table<br />5- simple navigation<br />6- usefull buttons<br />7- direct access for CLCPRO<br />
  33. 33. Weneedalso: a warning system<br /> to track the updates<br />Data updated<br />Data are not updated<br />Updates indicatorsbased on the last updates<br />… for each record<br />Exemple for car spares<br />
  34. 34. Critical point ?<br />The sustainability of this monitoring system could be demolished by the vicious circle of locust control<br />copied on the invasion cycles but result of the human behavior<br />Data updates<br />Without frequent updates, the system will never be operational. We must evaluate and monitor the effectiveness of the updates during the implementation of the application<br />Oblivion / Interests<br />
  35. 35. MOTIVATION PHASE <br />Awakening of the problem<br />Late and expensive control operations <br />Invasion not controlled at an early stage<br />Funds abundant<br />New equipments<br />New researches<br />2004<br />2003<br />1988<br />1987<br />Favourable ecological conditions<br />Where we are<br />Recession<br />Obsolete means and nonoperational organizations <br />Problem forgotten or considered solved<br />Few funds<br />Low motivation<br />OBLIVION PHASE<br />The locust phasis theory applied to Man and Institutions<br />
