Agriculture in India600M agriculture-dependent lives
Majority small landholders (<3 acres)
<$2 a day ($750 a year)
Growing debts ($300 per year per farmer)
Earlier technology intervention…– Green revolution had mixed results
• Increased yields, but…• Led to rising input costs, declining soil
fertility• Due to excessive use of
fertilizers/pesticides
Indiscriminate use of technology partially responsible for current agrarian crisis

Agriculture Extension
Dissemination of expert agriculture information and technology to farmers
“Training & Visit” extension popularized by the World Bank in 1970s
– Face-to-face interactions of extension officers and farmers
100,000 extension officers in India– Extension agent-to-farmer ratio is
1: 2,000– 610,000 villages in India with
average 1,000-person population
Typical extension officer salary isRs. 4,000 per monthExtension officer “commuting” between farms
IT & Indian Agriculture
• Kiosks with Internet access
for farmers
• aAqua– Pull-based Question and Answer Krithi Ramamritham, IIT Mumbai

How can the speed and effectiveness of agriculture extension be improved at a reasonable cost?
The Problem

Video provides…– Resource-savings: human, cost, time– Accessibility for non-literate farmers
Digital Video for Extension

Participatory Content Production

Digital Green System
Introduction to innovations– Standard extension
procedure
Rough “storyboarding”– Repetitive pattern; easy to
learn– Minimize post-production
Local farmers on their own fields– Reduce perception of
“teachers”– Promote “local stars”

Digital Green System
Video Database
Online video databasehttp://www.digitalgreen.org
>1,300 videos of 8-10 minutes each
Quality-control, minor video editing, and metadata tagging
Indexed by type, topic, locale, season, crop, etc.
Distributed via memory cards

Mediated Instruction
Local mediator– Performance-based honorarium
Human engagement– Field questions, capture feedback,
encourage participation– Balance genders
On-demand screenings – Choice time and place– Not “stand-alone” kiosk
Support and monitoring – Daily metrics and feedback– Official extension staff

21 villages in Karnataka:– Language: Kannada– Crops: Ragi, banana, mulberry, coconut– Population: 50-80 households– Irrigation: 10-20 households with access– Television: 15-20 households
Metrics:– Knowledge: Before-and-after– Attendance: Farmers at each screening– Interest: Intent to take-up a practice– Adoption: Number of households taking up
each new farming practice or technology

15 months: 13 villages, 3 nights a week, 1,000 regulars
Sustained local presence
Mediation
Repetition (and novelty)
Integration into existing extension operations
Social homophily between mediator, actor, and farmer
Desire to be “on TV”
Trust built from identities of farmers and villages in videos

Viral Web 2.0 in the Web-less world - Content ecosystem: education, entrepreneurship, entertainment - Cost-realistic access: pico projectors, TVs, DVD players, and camcorders
Reinforce existing social networks to diffuse innovations through communities

Could DG also be supported by ads?
Advertisers get access to a distributed, captive audience with demonstrated interest in better agriculture.
Ads follow Digital Green’s distribution channels.
To do: – Scale Digital Green– Devise mechanism for ensuring
appropriate ads– Quantify ad effectiveness– Quantify ad value to advertisersDigital Green DVD title screen
