A new approach to rural development

ByAllah Dad Khan

[email protected]

The Farmer Field School (FFS) is a group-based learning process that has been used by a number of governments, NGOs and international agencies to promote Integrated Pest Management (IPM).

By the end of the 1980s, a new approach to farmer training emerged in Indonesia called the 'Farmer Field School' (FFS). The broad problem which these field schools were designed to address was a lack of knowledge among Asian farmers relating to agroecology, particularly the relationship between insect pests and beneficial insects

Prophylactic, calendar- based spraying

Heavy subsidy on pesticides (80%)

History of Farmer Field School

Outbreak of BPH during 1970-1980s

The first IPM Farmer Field Schools were designed and managed in 1989 by experts working for the UN Food and Agriculture Organisation (FAO) in Indonesia. This was not, however, the first attempt made by FAO to extend IPM techniques to farmers in South East Asia.

FFS is is a group extension method based on adult education program that utilizes discovery learning and participatory techniques.

Composed of groups of 25-30 farmers who meet regularly during the course of the growing seasons.

FFS aims to increase the capacity of groups of farmers to carry out experiments in their own fields.

The facilitator is called a field leader (FL). The FLs are trained in both technology and facilitation skill in a program called a Training of Trainers (TOT).

History Farmer Field School

What is a Farmer Field School

Farmer Field School is a school without walls. Farmers and extension workers are students. The Farmers Field is the class room and the plant is the teacher. As the plant grows the students gain knowledge in the light of their observations. The get together at a fixed time every week once and make their own decisions based on observations and data analysis for the health of the plants.

1. Skill Development

2. Empowerment

3. Will power

4. Capacity of Decision Making

Grow a healthy crop

o Resistant varieties, proper fertilzers, water and soil management, etc

o Healthy crop can resist diseases and compensate for damage

Observe fields regularly

o To assess crop development, diseases, insect pest population, and natural enemies.

Conserve natural enemies of crop pests

o Abundance of natural enemies in the field

Avoid the use of pesticides that kill natural enemies

Farmers understand ecology and become experts in their own field

Make decisions based on observations and analysis of the field situation

The Target Group- Farmers

Resource deficient, Illiterate, Traditional, inward looking

Objectives Poverty alleviation.

Enhanced Productivity Reduced Costs

Social Organization Group formation (pressure Groups) Conflict Resolution (Debate and consensus

building)

Empowerment and removing dependencySetting Research AgendasTo do own research

•Natural Resource Management

•Freshwater use•Soil Conservation•Environment protection

•Health consciousness

•Livelihood improvement through Technology Use.

Putting it in Perspective

Products vs Knowledge based Technologies Knowledge vs Skill Development

Learning by doing vs by seeing Discovery based learning Decision making vs following advice Situation based vs Technology based development Participatory vs Empty barrel approach

What is IPM for a Farmer ?

Integrated Pest Managementor

Increased Profit Margins

Only farmer can make the “right” Farm Management decision based on his own perceptions of economics and technologies.

So farmer should be trained in decision-making There are too many farms (5.00 mill) and too few extension workers

to be able to service them all.

A self multiplying training programme for farmers need to be established.

Each farmer field is different in pest, beneficial fauna, soil and other eco-system elements and cannot be treated on a generalized technology package message.

Technologies requiring decision-making and management need skill transfer training.

IPM cannot be implemented simply by demonstration, field days, TV Ads, radio, publications etc.

Training of Facilitators

TOF: Training of Facilitators Activity guided by a facilitator who has been trained before hand CHARACTERISTICS

One complete growing season Learning by doing Growing own crop (regular observations on

plant development) Carry out FFS Group dynamics (serve as preparation for

trainees to conduct FFSs themselves and to gain facilitation skills)

Fostering corporate identity (provides joint spirit which is crucial factor for the success)

FFS: Farmer Field School

•Non formal adult education

 

•CHARACTERISTICS

     One complete growing season

     Discovery based learning in the field

 Conducting experiments (insect zoo, herbivore- predator trials in cages, defoliation experiments etc)

     Working in groups

•Horizontal learning by fellow farmers

TYPICAL SEQUENCE OF FFS

     Agro-eco-system analysis

       drawing (observations are assembled in large drawings showing plant, pests on one side and beneficial insects on the other side)

Process of Farmer Field SchoolGroup Dynamics

To foster cooperation and togetherness within the group To sharpen farmer

communication and organizing skills

FFS starts with a ballot-box pretest of knowledge and ends with a

posttest A simple tool to measure the level of a farmer’s knowledge on an agroecosystem Questions focus on:

recognition of pests, natural enemies, diseases recognition of damage from pests and diseases management of pests and diseases etc

Process of Farmer Field SchoolBallot Box

At the end of FFS season

To show the results of FFS to other farmers, agricultural staff, local government officials.

o IPM plot vs Farmer Practice plot

o Other field experiments

o Insect zoo (pests and natural enemies)

Process of Farmer Field SchoolField Day

One-week training is conducted for farmer trainers prior to organize farmer-led FFS;

Curriculum of TOT includes facilitation and management skills for organizing an FFS, and review and discuss background of FFS topics, e.g. agro-ecosystem analysis.

Farmer-to-Farmer FFS are implemented in the same way, except the trainers are farmers.

Key elements in the development of IPM over large areas.

Follow-up Activities

Farmer IPM Field Studies

To develop farmer’s own knowledge and technologies;

To develop a capacity to find an answer/proof or to test a method;

To develop farmer’s capacity on research and its networking with research-related

institutions.

Follow-up Activities

Making plant extracts for botanical pesticides and testing the effectiveness

Farmer IPM Field Studies

Study on effects of plastic mulch Study on effects of bamboo staking in potatoes

Follow-up Activities
