In the 2019 Special Report on Climate Change and Land, 联合国政府间气候变化专门委员会(IPCC)警告说，气候危机将对农业和林业产生巨大影响. At the same time, the report makes clear that arable farming, 畜牧业和林业是全球变暖的主要贡献者，呼吁这些部门最终承担责任，发起变化，遏制气候变化.
不可持续的农业是造成这场危机的原因之一，因为用于种植粮食的人造肥料造成了粮食短缺 多数 of nitrous oxide released into the atmosphere as a result of human activity. Nitrous oxide has almost 300倍 the warming effect of carbon dioxide and is responsible for about six percent of annual greenhouse gas emissions globally.
We believe that limiting global warming to 1.5°C (2.7°F)仍然可以通过大幅削减化石燃料排放，以及基于有机原则和农业生态学改造AG体育app下载的粮食系统来实现. Given its potential for reducing carbon emissions, enhancing soil fertility and improving climate resilience, 有机农业应该成为解决未来全球营养和应对气候变化的综合政策工具的基础.
Organic agriculture can help with climate change by:
- Reducing greenhouse gases, especially nitrous oxide, as no chemical nitrogen fertilizers are used and nutrient losses are minimized.
- Putting carbon back into soils by keeping them covered with plants, increasing crop diversity, composting and carefully planned grazing.
- 通过减少生产合成肥料所需的能源，使每单位土地的能源消耗减少30-70%, and by using internal farm inputs.
