水稻生产排放方法与创新：经济评估与现实可行性分析

稻米生产是世界各地数百万人的粮食安全和经济生计的基石，特别是在以稻米为主食的亚洲。

然而，传统的水稻种植会严重排放温室气体（GHG），特别是甲烷（CH2）和氧化亚氮（N2O）。随着世界人口的成长（预计到 2050 年将增加 34%），稻米生产面临越来越大的压力，既要满足需求，又要尽量减少对环境的影响。

近年来，包括欧盟绿色协议和全球甲烷承诺在内的全球政策和倡议都将减少农业排放作为实现气候变迁目标的关键步骤。特别是，欧盟绿色协议的目标是欧盟到2050年实现气候中和，中期目标包括2030年减少50%的化学农药使用量和20%的化肥施用量。这些法规不仅影响欧洲市场，也影响与欧盟有大量农产品贸易的国家，透过补贴、碳信用和技术投资鼓励永续做法。

虽然稻米生产对全球粮食安全至关重要，但其高温室气体 (GHG)排放使其越来越面临适应永续做法的压力。光是水淹稻田的甲烷排放就约占世界农业甲烷排放总量的 10-12%。随着环境法规的收紧和市场对永续性的需求的增加，美国工业正处于关键时刻，需要创新来平衡生产力与环境管理。

为了实现上述物种目标，水稻产业正在采用各种排放技术，包括干湿交替（AWD）、水稻强化系统（SRI）、精密农业工具和生物炭等土壤改良剂。这些方法不仅可以减少排放，还可以提高资源效率和作物产量。例如，AWD 可以减少高达 48% 的甲烷排放，而 SRI 则可以减少用水量并提高生产率，使其成为缺水地区颇具吸引力的方法。

本报告调查了水稻生产的排放方法和创新趋势，提供了旨在减少排放的各种政策和倡议、排放技术的类型和概述、主要国家排放技术的采用率和成功指标等信息，以及总结了排放技术的经济评估。

Market Introduction

Rice production is a cornerstone of food security and economic livelihood for millions worldwide, particularly in Asia, where rice serves as a staple food. However, traditional rice cultivation practices contribute significantly to greenhouse gas (GHG) emissions, especially methane (CH2) and nitrous oxide (N2O), primarily due to flooded field conditions and fertilizer usage. As global populations grow, with an anticipated 34% increase by 2050, the pressure on rice production to meet demand while minimizing environmental impact is intensifying.

In recent years, global policies and initiatives, including the EU Green Deal and the Global Methane Pledge, have emphasized reducing agricultural emissions as a critical step toward achieving climate targets. The EU Green Deal, in particular, aims for the EU to achieve climate neutrality by 2050, with interim targets such as a 50% reduction in chemical pesticide use and a 20% reduction in fertilizer application by 2030. Such regulations not only influence European markets but also affect countries heavily engaged in agricultural trade with the EU, incentivizing sustainable practices through subsidies, carbon credits, and technological investments.

Industrial Impact

The rice production industry, while essential to global food security, faces increasing pressure to adapt to sustainable practices due to its significant greenhouse gas (GHG) emissions. Methane emissions from flooded rice paddies alone contribute approximately 10-12% of total global agricultural methane emissions. With heightened environmental regulations and market demands for sustainability, the rice industry is at a critical juncture, requiring innovations that balance productivity with environmental stewardship.

Key policies such as the EU Green Deal, Global Methane Pledge, and national climate commitments are pushing countries to implement emission reduction strategies in agriculture, including rice farming. For instance, under the EU Green Deal, the European Commission (EC) has set ambitious goals for the agricultural sector: reducing pesticide use by 50%, fertilizer use by 20%, and shifting 25% of farmland to organic practices by 2030. These regulations influence not only EU rice markets but also impact major rice-exporting countries that trade with the EU, spurring them to align with sustainable practices.

To meet these targets, the rice industry is embracing various emission reduction technologies such as Alternate Wetting and Drying (AWD), System of Rice Intensification (SRI), precision agriculture tools, and soil amendments like biochar. These methods not only decrease emissions but also enhance resource efficiency and crop yields. For instance, AWD can reduce methane emissions by up to 48%, while SRI reduces water use and improves productivity, making it an attractive method in water-scarce regions.

Several industrial players, including agricultural technology firms and seed producers, are developing new tools to support emission reduction in rice farming. Companies like Deere & Company and Syngenta have invested in precision agriculture equipment, while BASF SE and Yara International are working on low-emission fertilizers. Additionally, collaborations between governments and private enterprises are on the rise. Through programs like the EU's Horizon 2020, funding and incentives are directed towards sustainable rice production initiatives, including water-saving technologies, controlled-release fertilizers, and smart agriculture practices.

Despite these advancements, the industry faces significant challenges. The high initial cost of technology, limited access to funding for smallholder farmers, and inadequate technical support hinder the large-scale adoption of emission reduction methods. Moreover, successful adoption of data-driven systems like Variable Rate Technology (VRT) or Data Management Supporting Systems (DMSS) requires robust infrastructure and digital literacy, both of which are often lacking in rural rice-growing regions.

Nonetheless, the industry impact of emission reduction in rice farming is promising. By implementing sustainable practices, rice producers can improve their resilience to climate impacts, gain access to carbon credit markets, and meet rising consumer demand for sustainable products. If adopted widely, these practices could contribute significantly to reducing global agricultural emissions and advancing climate goals, while also opening new economic opportunities within the rice production sector.

Adoption of Water Management Practices-particularly Alternate Wetting and Drying (AWD)

A crucial factor in reducing emissions in rice production is the adoption of Alternate Wetting and Drying (AWD), a water management practice that lowers methane emissions by up to 48%. Unlike traditional continuous flooding, AWD involves intermittently drying fields, which interrupts methane-producing bacteria. This method not only reduces emissions but also cuts water use by about 30%, benefiting areas with water scarcity and lowering irrigation costs. AWD is cost-effective and accessible for smallholders, yet challenges remain, including the need for farmer training and technical support. With proper incentives and support, AWD has the potential to be a cornerstone in sustainable, low-emission rice farming.

Recent Developments

• Public-Private Investments: Programs like the EU's Horizon 2020 have funded numerous projects in sustainable rice farming. Companies such as Deere & Company, Syngenta, and Yara International are developing and promoting technologies like controlled-release fertilizers, precision irrigation, and crop monitoring systems to support emission reduction goals.
• Adoption of Smart Farming Technologies: Precision tools such as Variable Rate Technology (VRT) and drones are gaining traction in major rice-producing regions. These technologies enable optimized use of water, fertilizers, and pesticides, reducing emissions and conserving resources.
• Carbon Sequestration Initiatives: Agroforestry and conservation tillage in rice paddies are being adopted to enhance soil carbon storage. Countries such as India and Vietnam are integrating carbon credit programs with these practices, creating financial incentives for farmers to adopt sustainable techniques.
• Government-Led Incentives: Governments in Asia, the U.S., and the EU are introducing incentives, subsidies, and carbon credits for emission reduction technologies in rice production. Vietnam's VnSAT project and India's National Action Plan on Climate Change (NAPCC) offer support for farmers adopting water-saving methods like AWD and SRI.
