农业生产历来是人类社会的重中之重。在我们几千年的历史中，农作物、纤维物以及其他生态产物的耕种与收获见证了数百亿人的生命足迹。 农业生产技术的发展逐步提高了人类文明所赖以生存的粮食安全保障，并在很大程度上推动了人类文明的繁荣与昌盛。然而，在农业生产的过程中所利用的土地和水资源，以及动植物本身都会释放大量包括甲烷在内的温室气体（GHG）以及其他短寿命气候污染物 （SLCP）。
虽然我们位于全球多处的‘完善管理方式、开发创新科技以及提高农民环保意识’项目初见成效，并有效提高了农业生产效率以及减少了每单位产物的温室气体排放，我们的努力还远远不够。农业及林业生产（已纳入近期土地利用改变）的污染物排放占全球温室气体排放量的22%，其中包括全球黑炭排放量的大约40%，以及约等于40%的全球人为甲烷排放。
即便如此，农业行业本身极其容易受到温室效应的影响。可能受到影响的原因包括：降水量变化、极端天气影响以及对流层臭氧增加所导致的农作物产量下降。降低SLCP排放可以有效减缓短期全球暖化、提高空气质量以及控制空气污染对于农业生产效率的影响。 作为空气污染的重灾区，对于南亚以及东亚的农民朋友来讲，控制SLCP排放尤为关键。我们的研究预测，立即创立并执行有效措施以减少全球SLCP的排放可以在2030年前达到每年可避免大约5000万吨粮食作物流失的成效。在这项预测中，如玉米、大米、大豆以及大麦等农作物可以为各个地区带来的经济效益可达400亿美元至3300亿美元，其中200亿美元至2800亿美元源自亚洲。我们的努力还可以在2050年以前帮助避免将近0.5˚C的全球变暖。
气候与清洁空气联盟的农业倡议包含四个'部分'，或工作方向。 这些是：
1）畜禽以及粪便管理;
2）开放式农业焚烧;
3）水稻种植; 和
4）肠道发酵。
我们正在开发相关的横向拓展以及交流项目，敬请期待。
The Agriculture Hub is co-led by Costa Rica, United States, and Vietnam. Co-leadership by countries ensures government engagement and ownership of the solutions. Co-leads provide valuable insights into the policy process to help ensure implementation is practical from a national perspective.
The Agriculture Leadership Group consists of both state and non-state members that provide guidance and expertise, and connect the Hub to activities underway beyond the CCAC.
The CCAC Agriculture Initiative is the first action-oriented global effort to reduce methane and black carbon emissions from key agricultural sectors by sharing and implementing best practices, in order to enhance food security and livelihoods in accordance with broader climate change objectives.
The Initiative focuses on identifying and facilitating the implementation of best management practices and technologies tailored to national and local circumstances. This includes needs assessments and studies, raising awareness, training & capacity building, and working with farmers, policymakers, and other stakeholders to overcome barriers to implementation.
The Livestock and Manure Management component aims to facilitate policy and local-level practice change through marginally improving production practices while keeping production levels constant.
The objective of the Open Agriculture Burning component is to replicate and scale up open burning mitigation options as a result of a) determining the nature of open burning (who burns what, when, where and why) in the target regions of the Eastern Himalayas and Andes and b) creation of regional open burning networks and partners by convening two regional conferences that will feed into project goals and outcomes through information sharing, and c) the development of shovel-ready pilot mitigation projects with specific actions targeted to each region and crop type.
The Paddy Rice Cultivation component seeks to reduce methane emissions from paddy rice production by promoting alternative cultivation practices and educating rice producers, as well as creating enabling conditions to overcome barriers for improved agricultural methods.
The Enteric Methane component aims to transform ruminant livestock production systems in order to reduce emissions of enteric methane per unit of product, and increase efficiency.
The CCAC has helped governments identify ambitious actions, policies and targets to cut short-lived climate pollutant emissions from enteric methane, rice, manure, and burning. Our work has laid the foundation for action by establishing locally appropriate, affordable and technically feasible measures. Our key achievements include:
National policy
29 CCAC partners have included specific agriculture measures in their updated NDCs. 16 mention enteric fermentation, 15 manure management, 11 rice production, and 8 open burning.
Paddy rice
Livestock
14 countries demonstrated the potential for reducing enteric methane to stimulate immediate investments.
Open burning
Other
Leveraged $461,100,000 in co-funding for SLCP mitigation in agriculture
Helped 4 countries include mitigation from agriculture in their NDCs.
Lead Partner: A Coalition partner with an active role in coordinating, monitoring and guiding the work of an initiative.
Implementer: A Coalition partner or actor receiving Coalition funds to implement an activity or initiative.
