Rice-fish culture: Integrating rice and fish farming systems

Rice-Fish System Boosts Profits, Enhances Lowland Land Use for Food Security and Prosperity

Rice-fish co-culture ensures food and nutrition security by synergistically cultivating rice and fish. This sustainable method boosts small farmers' income through rice and fish sales while maintaining environmental safety by eliminating agrochemical use. Overall, it's an innovative and efficient approach to enhance food security, economic stability, and environmental sustainability.

This technology is pre-validated.

9•7

Scaling readiness: idea maturity 9/9; level of use 7/9

Adults 18 and over: Positive high

The poor: Positive high

Under 18: Positive high

Women: Positive high

Climate adaptability: Highly adaptable

Farmer climate change readiness: Significant improvement

Biodiversity: Positive impact on biodiversity

Carbon footprint: A bit less carbon released

Environmental health: Greatly improves environmental health

Soil quality: Improves soil health and fertility

Water use: More water used

Problem

Food and Nutrition Insecurity:
- Insufficient access to a diverse and nutritious food supply.
- Lack of dietary variety leading to nutritional deficiencies.
Market Vulnerability for Smallholder Rice Farmers:
- Dependency on a single crop (rice) makes farmers susceptible to market fluctuations.
- Limited income diversification options contribute to economic instability.
Environmental Pollution from Agrochemical Use:
- Excessive application of agrochemicals contributes to soil and water pollution.
- Negative impact on biodiversity and ecosystem health due to chemical runoff.

Solution

Enhanced Profitability:
- Increased economic viability with a higher benefit-to-cost ratio (2.2) compared to sole rice cropping (1.6).
- Addresses the problem of widespread food and nutrition insecurity by improving economic returns.
Market Resilience for Farmers:
- Rice-fish farmers demonstrate greater resilience to market shocks, mitigating vulnerability.
- Diversified income sources from both rice and fish sales contribute to economic stability.
Nutrition Security through Fish Consumption:
- Fish consumption directly addresses the challenge of nutritional deficiencies.
- Enhances food security by incorporating a more diverse and nutritious diet.

Scaling Readiness describes how complete a technology’s development is and its ability to be scaled. It produces a score that measures a technology’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.

The United Nations Sustainable Development Goals that are applicable to this technology.

Goal 2: zero hunger

Goal 3: good health and well-being

Goal 8: decent work and economic growth

Goal 13: climate action

Goal 1: no poverty

Field Preparation:
- Ploughing and leveling the rice field while constructing bunds for water retention.
Pond Refuge Construction:
- Building a pond refuge across the field's width to provide water for fish during reduced water levels.
Predator Protection:
- Installing a welded wire mesh fence around the field to safeguard fish from predators like snakes.
Rice Transplanting:
- Transplanting rice seedlings into the prepared field.
Irrigation:
- Providing irrigation to maintain optimal water levels in the field.
Fish Stocking:
- Introducing fingerlings into the field for the establishment of the fish component.
Bird Protection:
- Covering the entire field with nets to prevent predatory birds from affecting fish and rice crops.
