节水抗旱稻全产业链创新联盟：加速形成“品种+技术+碳核算”方案

Core Viewpoint - The water-saving drought-resistant rice is a significant agricultural technological achievement in China, capable of saving 50% water and reducing methane emissions by over 90% [1][2] Group 1: Agricultural Innovation - The water-saving drought-resistant rice integrates high yield and quality of traditional rice with drought resistance and water-saving features, allowing for cultivation without flooding and achieving similar yield and quality to regular rice while saving over 50% water [1] - The technology has been recognized with multiple awards, including the second prize of the National Technology Invention Award in 2013 and the first prize of the National Science and Technology Progress Award in 2020 [1] - The total area promoted for water-saving drought-resistant rice has exceeded 30 million mu, with an annual planting area of 5 million mu [1] Group 2: Environmental Impact - The drought-resistant rice cultivation method can reduce greenhouse gas emissions by over 90% compared to traditional flooded rice cultivation, with methane emissions reduced by over 97% [2] - The carbon reduction methodology for this rice has been successfully registered, leading to additional carbon reduction revenue of 460 yuan per hectare, potentially generating an annual income of 18.4 million yuan based on a planting area of 400,000 hectares [2] Group 3: International Outreach - Since 2008, the water-saving drought-resistant rice has been tested and promoted in several African countries, with five varieties approved in four countries by the end of 2024 [3] - In Uganda and Ghana, 120,000 mu have been demonstratively promoted, resulting in an increase of over 7.2 million kilograms of rice and helping local farmers earn over 10 million yuan [3] - The research team aims to achieve the "1522" development goal, which includes increasing rice planting area by 100 million mu, producing an additional 50 billion kilograms of rice, and reducing water usage by 20 billion tons [3]
