- Rice cultivation: 7.4 millions ha/year - Rice production: 38.9 mill tons of paddy rice/year
- Corn area: 1.14 million ha- Vegetable area: 720,000 ha- Coffee area: 525,100 ha - Sugarcane area: 270,000 ha
VIETNAMVIETNAM
There are several existing problems in rice cultivation:
• Overuse of pesticides
• Overuse of chemical fertilizers (especially nitrogen)
• High transplanting density
BackgroundBackground
BackgroundBackground
Causing problems:• Rice crop is susceptible
to pests, resulting in decreased yield, less economic efficiency, and deteriorating environmental quality.
• Pesticides kill natural enemies, causing pest outbreaks
• Overuse of chemicals (fertilizer, pesticide, etc.) will pollute the environment, affecting environmental health.

• In 2003, National IPM Program Vietnam introduced SRI to the farmers for experimental application.
• From 2003 to 2004, farmer groups under IPM/BUCAP auspices applied SRI under various practice conditions
• In years 2005 and 2006, SRI was applied in demonstration plots of 2-5 ha that showed SRI having any advantages in comparison with conventional practice (DANIDA support)
• In 2007, Vietnam conducted a pilot model of “community-based SRI application” on the large scale of 170 ha in Ha Tay (supported by OXFAM America)
• On 15 Oct. 2007, the Ministry of Agriculture and Rural Development (MARD) issued a decision acknowledging SRI as an ‘advanced technology’
BackgroundBackground
• From Sept. 2007, OXFAM America launched a 3-year program “Advancing Small Farmers in Mekong Region with SRI” (VIE 034/07) to assist Vietnam for scaling up the SRI utilization
• Programme has been conducted in collaboration of the Government and NGOs in Vietnam: the Plant Protection Department under MARD; Oxfam Quebec; and Centre for Sustainable Rural Development (SRD), as well as Oxfam America

Approach:Approach:
Purposes: • Strengthen farmers’ capability with self-developing
mechanisms to manage their resources. • Institutionalize SRI applications in the commune level
Develop-ment of SRI should go through a series of stages
Steps to utilize SRI:
Farmer group in Hoa Binh Province doing observations in their study field
Steps to utilize SRI:
Full draining of the field
1st stage (first season activities): study the principles of SRI through the Farmer Field School (FFS) process with farmers managing together a trial/demonstration field
Young seedlings
2nd stage (2nd and 3rd season activities): practicing the utilization on SRI in a larger scale (within 5 ha)
Steps to utilize SRI:
Making the beds 2 meters wide Canal made between two beds
3rd stage (after two or three seasons): extension of SRI in the whole community
Steps to utilize SRI:
SRI applied in 50 ha of traditional sticky rice in Thuy Lam Commune, Dong Anh District, Hanoi, in summer crop season, 2010
• 4th stage: farmer groups will continue to improve SRI techniques and improve cultivation practice in order to have better production and better market access.
(Stage 4 can be incorporated in stage 3)
Steps to utilize SRI:
Burning straw and stubble might kill natural enemies and harm the soil ecology; also health hazard
Farmers develop minimum tillage Farmers develop minimum tillage with potato productionwith potato production
Basal fertilizer application
Mulching
Farmers observe agro-ecosystem
Farmers develop minimum tillage Farmers develop minimum tillage with potato productionwith potato production
In comparison with conventional practice, these new practices:
- Reduce soil preparation labor by 40% - Reduce harvest labor by 70% - Increase yield by 8.3-20%- Increase profits by 31%
Develop rice production in compliance
with VietGAP standard

SRI Application and SRI Application and Water SavingWater Saving
Summer seasons 2005 & 2006
Summer season 2008
Farmers saved about 30% of water volume
Reduced irrigation cost by 33% to 40-50%
LimitationsLimitations
• SRI irrigation management needs a strong collaboration among the community
• Financial support for expansion is still limited
• Organic manure resources are limited; need to make better use of straw and other biomass to reduce fertilizer need
Strategy:Strategy:
• Strengthen collaboration with Cooperatives, Mass Organizations (Farmers’ Unions, Women’s Unions, Youth Unions…) for better support of farmer groups to develop SRI in their localities
• Priority is given to women’s participation in the learning process to improve their knowledge and skills needed to identify problems and find solutions to solve problems.
Strategy:Strategy:
• Diversify the communication work in order to disseminate and share better the experiences and achievements of SRI among communities and to advocate the policy support for SRI expansion
• Build up the core farmers as resource persons in each commune
• Study the potential and conditions for market access of SRI produce (higher quality)
• Develop weeding and aeration tools for local conditions, and improve their supply
• Improve soil ecology: minimum tillage, inter-cropping with beans, adding green manure crop
