Climate smart agriculture in shrimp rice production in Mekong delta

About the Implementing organization

Name: Bac Lieu Provincial Association of Farmers (PAF)

Country: Viet Nam

Year of establishment: 2014

Type of organization: Community-based association or organization

Description

The project’s interventions are innovative because:
- The rice-shrimp farming model developed by the project now is still sustained under severer drought and saltwater intrusion conditions.
- The model helps local farmers enable to reduce their application of agrochemicals to prevent environmental impacts and preserve the ecological balance of their fields and soil fertility.
- The model also helps reduce costs incurred in the production because of nutrient cycles or an ecological recycling that occur in fields/ponds where rice residues left behind after harvesting decompose and generate plankton organisms as feeds for shrimps, and thus no more feeds need to be added if the density of shrimp raising accounts three shrimps per square meter. This results in reduction in costs incurred, and because of no excessive feeds/residues, the pond’s water environment is well protected and thus shrimps grow well and their wastes are best organic matters to fertilize the soil.
- By combining the indigenous knowledge with field cleaning technique, the model helps to reduce the application of fertilizers per crop by 20-25% .
- The model produces clean products.
- Solutions to the model development is community- driven.

Environmental Impacts

- In the model there is little and even on negative impact on surroundings because closed nutrient cycles and/or an ecological recycling occur in the field/pond.
- The rice-shrimp farming model has been sustained under drought and saltwater intrusion conditions, which helps improve the preservation of the environment and ecology of the farming area, prevent soil deterioration and minimize risks of various epidemic disease.
- Environmental pollution has been minimized due to the application of agro-chemicals (N-P-K fertilizers and pesticides) was reduced by 80%. Thus, toxic chemical residues were much reduced in soil and water, and as a result the products meet the food hygienic and safety standards and the Good Agricultural Production (GAP) requirements, and increase their commodity values, contributing to the protection of community health.

Sustainable Development Impacts

  * Economic Impact: the model has been proven economically effective by improving rice and shrimp farming productivities attributed to the model that is appropriate to natural ecological conditions, adaptive to climate changes, and suitable for local farmers’ technical capacity and for the Mot Bui Do rice that is well resistant to rice-blast-disease and brown-hoppers, and well grown, gives high yields with lower costs and its grains are quickly sold at high profit.
* Social Impact: The model has attracted local community’s participation. The project has provided 129 farmer households with technical and financial supports for their production, helped local farmers enable to effectively improve their farming techniques, and the model has been widely replicated throughout the region.
* Environmental Impact: the model has contributed to improving the quality of rural environment and sustainably preserving agricultural ecosystems.

Scalability

The local government appreciated the demonstration and do have plan to widely expanded the model to the rest of the district about 9000 ha.

Replicability

Rotation of Mot Bui Do rice and grass shrimp crops bring high economic values, and coastal areas of the Mekong Delta have high potentials and greater advantages, and there is a plenty of opportunity for for local communities to enrich themselves if they know how to apply advanced farming techniques in combination with their indigenous knowledge. The replication of the project’s demonstration model in four villages (Phước Thành, Phước Thọ, Thọ Tiền, Phước Trường) of Phước Long commune will be upgraded in terms of its scale and efficiency, and widely duplicated to other villages and communes throughout Phước Long district. This will contribute to dealing with the effective use of local land, water and biodiversity resources in the saltwater contaminated soil areas, and help local farmers of two ethnic groups - the Kinh and the Khmer, enable to improve their capacity to adapt to climate change, and their awareness of its adverse impacts on their living conditions .
