Abstract
A participatory planning process was applied in two resource management initiatives in Vietnam. The first
case was a pilot project established in two districts of Long An province to evaluate the use of media
materials to motivate farmers to experiment or test a simple rule: “insecticide spraying for leaf folder
control in the first 40 days is not needed”. The second case was a research-extension initiative launched in
Cantho province to motivate farmers to reduce seed rate and use of fertilizer and pesticides. The media
campaign in Long An province resulted in a 53% reduction in insecticide use and no loss in production in the
project sites, and the change eventually spread to more than a million rice farmers 3 years later. Leaf folder
control perceptions, expressed as the belief index, changed from 11.25 to 7.62. The belief index is the sum
of scale ratings of belief statements presented to respondents. A three-point Likert scale (1 for the preferred
answer, 2 for indifference and 3 for the not preferred) was used to score components of belief about leaf
folders. The study showed that mass media could effectively transfer some elements of knowledge-
intensive pest management, especially simple non-site specific information designed to motivate. The
case studies highlighted the need for processes that distill bits of information and develop them into
knowledge that can be communicated and used by farmers to make resource management decisions.
Some of the features found to be extremely useful in implementation are: developing high quality
partnerships and building social capital, building project objectives within institutional objectives, using
mechanisms to encourage participation, encouraging farmer participatory research (FPR) to facilitate
farmers’ evaluation of heuristics, and developing a participatory communication strategy and materials
for evaluation.
Media summary
A media campaign developed through quality partnerships and stakeholder participation has motivated
millions of rice farmers in the Mekong Delta, Vietnam to reduce pesticide use.
Key Words
Participatory process, stakeholders, heuristics, media campaign, multiplier effects.
Introduction
For farmers to respond to opportunities that will improve their agricultural productivity, knowledge and
information play a central role. In many farming populations, access to information is often variable,
partly due to differences in farmers’ circumstances and ability to adopt technological options and
availability of extension-communication infrastructure. In some cases, information is not available or it is
disseminated through specific communication channels to which many households have limited access.
To be of benefit, information must be communicated and internalized effectively by its intended
beneficiaries (FAO, 2003).
Scientific achievements in rice research have been impressive considering their impact in Asia (Cantrell,
2002). From these scientific achievements, knowledge-based technologies could be derived to provide
more options to farmers and consumers. However, results often remain restricted to a few research
collaborators and farmers who have been trained while millions of other farmers are unable to benefit
from them. Despite the strides made in rice science, farmers’ knowledge and decision-making skills in
crop management have lagged behind. A number of examples can illustrate the gaps that exist between
scientific achievements and farmers’ practice:
• Modern rice varieties can easily yield 8 t/ha when well managed. However, a large proportion of
farmers still obtain yields of <5 t/ha. In the Philippines, the average yields in the on-farm
experiments from 1991 to 1995 were 5.7 t/ha during the wet season and 7.5 t/ha during the dry season
