What is AESA???
An approach, which can be gainfully employed by extension functionaries and farmers to analyse field situations with regard to pests, defenders, soil conditions, plant health, the influence of climatic factors and their interrelationship for growing healthy crop.

AESA Methodology
1. Field Observations: • Plant health at different stages • Built –in compensation • abilities of the plants • Pest and defender population dynamics • Rats • Weeds • Soil conditions • Climatic factors • Weather • Farmer past experience

• AESA by Extension
Functionaries
• AESA by farmers: After a brief exposure during IPM demonstrations/ field trainings, farmers can practice AESA in their own field.

AESA and Farmer Field School
• AESA is a season long training activity that takes place in the farmer field.
• it covers all the different developmental stages of the crop and their related management practices.
• Learner centered, participatory and relying on an experiential learning approach and
• Integral part of FFS.

AESA based IPM training for farmers
AESA based IPM training for farmers
Participatory
Learning through field experiments
Problem oriented
Learning about crop ecology
Understanding role of beneficial insects
Practical
Active involvement of the farmers
Regular meetings Throughout cropping season
Group meetings
Active involvement of the farmers
Not classroom training
Farmers learn from other IPM
Design studies to solve problems
Learning by doing
Farmers choose topics
Guided by IPM facilitator
