  1. Biology, Impact, Control What are the main species of rat in Bangladesh and how are they different from each other? Name four things that are special about rodent teeth. What is neophobia and why is it important? Why are rodents fast breeders and able to produce many young? Rodents and humans are mammals with similar physiology. Why is this important to know?

  2. Biology, Impact, Control Name 10 reasons why it is important to control rats. Name 3 reasons why rodents are important vectors and reservoirs of human diseases. Name 2 rat-borne diseases that are present in Bangladesh. What are the 3 things that rodents need to survive?

  3. Biology, Impact, Control Name 4 things that you can look for to indicate the presence of rodents. Why are chronic poisons better than acute poisons? Why might a farmer choose to use acute poisons instead of chronic poisons? Why are predators a poor rat control technique? Why is environmental management important when trying to control rat populations? What are the five steps to follow for rat management?

  4. Ecologically-Based Rodent Management

  5. Applied EBRM action

  6. Ecologically-Based Rodent Management Rodent biology • Species – behaviour, breeding rates, habitat utilisation, population dynamics • Damage • Holistic assessment – damage to agriculture, health, personal possessions and property

  7. Ecologically-Based Rodent Management Knowledge, Attitudes and Practice • People’s need to see dead bodies leads to use of acute poisons that are dangerous and ineffective in reducing rodent populations • Treatment failure leads to apathy and acceptance of rodent pests – e.g. “rodents are too clever to be controlled”

  8. Ecologically-Based Rodent Management Community-led strategy • Technology – effective, easy to use and durable • Population reduction – at the appropriate scale and time through trapping, anticoagulants, hunting, bounties • Environmental management – permanently reduce the carrying capacity through reducing access to harbourage, food and water, hygiene & sanitation, habitat modification

  9. Rodent Managers Everyone else – rural / urban settlements Farmers Households Communities • Qualified personnel – service providers • Pest Control Operators • Environmental Health Officers • Agriculture Extensionists

  10. Understanding the Manager

  11. Tools that we can use to understand the Rodent Manager Knowledge, Attitude and Practice Survey Community meetings

  12. Knowledge, Attitude and Practice Survey Community meetings Resource mapping / survey Tools that we can use to understand the Rodent Manager

  13. Knowledge, Attitude and Practice Survey Community meetings Resource mapping / survey Individual meetings / questionnaires Tools that we can use to understand the Rodent Manager

  14. Knowledge, Attitude and Practice Survey Community meetings Resource mapping / survey Individual meetings / questionnaires Observation Tools that we can use to understand the Rodent Manager

  15. Designing your KAP survey Culture Gender Education Language Experimental variables • Consultation • Pre-testing • Experience

  16. Are there generalisations we can make about Rodent Managers? • People like to see dead bodies • Poison should act fast – acute/chronic predicament • Underestimation of the damage caused • Limited microbiological & rodent ecology knowledge • Anthropomorphism • “Trap shy dogma” • The technology gap – can’t ask for unknown technology

  17. Ecologically-based rodent management Needs to be based on sound ecological and sociological data Must take account of local biological and socio-economic constraints Works best at the community level with a minimum number of freeloaders (social cohesion) Must convince Rodent Managers that their lives have significantly improved (economically, health, food security)

  18. EBRM Conclusions People underestimate the impact of rodents on their livelihoods Traditional rodent management practice has little impact on rodent numbers or damage caused Rodent pests can be successfully managed by communities armed with the right knowledge and tools Communities see results after implementing EBRM and rate it as economically and environmentally sustainable
