Building Trust in Carbon Credits Through Tokenized AWD Monitoring
Revolutionizing how we verify carbon credits in rice farming through tokenized alternate wetting and drying (AWD) data – bringing transparency, traceability, and trust to agricultural emissions reduction.
Understanding Alternate Wetting and Drying (AWD)
What is AWD?
Alternate Wetting and Drying is a water-saving irrigation technique for paddy rice that breaks the continuous flooding cycle. Fields alternate between flooded and non-flooded conditions as water levels drop to specific depths below the soil surface.
How It Works
Unlike traditional continuous flooding, AWD introduces oxygen into the topsoil during dry periods, suppressing methane-producing microbes. This simple change significantly reduces greenhouse gas emissions while maintaining or even improving yields.
Quantifiable Environmental Benefits
47-90%
Methane Reduction
Substantial decrease in methane emissions compared to continuous flooding, with studies showing reductions ranging from 47% in Bangladesh to potential 90% in optimal conditions.
15-35%
Water Savings
Significant reduction in irrigation water requirements, leading to conservation of critical resources and reduced pumping costs for farmers.
3-9%
Yield Impact
Properly managed AWD can maintain or even increase rice yields, as demonstrated by studies showing 3% yield increase in Bangladesh and 9% in the Mekong Delta.
The Verification Challenge

Trusted Data
Verified, tamper-proof field data
Advanced Monitoring
Technology-based solutions for precise measurements
Traditional Monitoring
Manual field water tubes with limited scalability
Traditional AWD monitoring uses perforated "field water tubes" to check when water levels drop 15cm below soil surface. This manual approach lacks the precision and verifiability needed for carbon markets, creating a critical gap in the monitoring, reporting, and verification (MRV) process.
