Smart Irrigation for Rice Farming
AT&T’s Internet of Things (IoT) solutions connect water-level sensors and pumps to help increase the control rice farmers have over their operations, and to overcome some of the barriers to Alternate Wetting and Drying (AWD) adoption. This helps to drive efficiencies, save water, and reduce carbon emissions.
The solution can:
• Help overcome barriers to AWD adoption and create higher use among farmers, resulting in measurable methane reductions and water and fertilizer savings;
• Become an important input for measurement and verification of carbon savings, which could help propel the nascent rice carbon offset market.
Rice is a resource intensive crop:
• 2.5 million acres of land in US;
• 40% of global irrigation water;
• 1.5% of global GHG emissions.
For one farmer, connected water-level sensors have reduced water usage by up to 60%, while the connected controls have reduced pump energy usage by 20-30%.
Potential Environmental Benefits of AWD:
• Annual Water savings: 80,000 US gallons per acre;
• Annual GHG savings: 0.28 metric tons CO2e per acre.
