什么是再生农业？

The potential of regenerative agriculture

Modern agriculture is at a crossroads. We are faced both with the need to feed an ever-growing global population, and the devastating soil degradation caused by intensive farming. 

The agriculture, forestry and other land uses (AFOLU) sector is one of the largest producers of greenhouse gasses, estimated by the IPCC to cause 21% of total anthropogenic emissions. At the same time, it holds the rare potential to not just drastically reduce emissions, but to sequester atmospheric carbon back into the soil, providing a natural way to limit global warming whilst producing nutritious food. 

Regenerative agriculture is a way of farming that improves soil fertility whilst sequestering and storing atmospheric CO2. It increases on-farm diversity and improves water and energy management. It is a holistic solution that can lead to a wider set of economic, environmental and social benefits.  

Farms using regenerative practises can benefit from: 

• higher and more stable yields 
• lower input costs 
• the development of natural capital and ecosystem services whilst building agricultural resilience. 

One study suggests that, if all global agricultural land was converted to regenerative farming systems, it would have the potential to sequester over 37.5 Gt of carbon dioxide per annum, which is more than the current level of global emissions. 

Regenerative practices

Regenerative practices work with nature, limiting costly artificial inputs and mimicking natural ecosystems within an agricultural setting. Their overarching objective is to restore soil health.  

Regenerative agriculture draws its practices from agroecology, permaculture and conservation agriculture, as well as having deep roots in Indigenous land stewardship.

再生农业没有统一的方法，因为它在很大程度上取决于每个农场独特的环境条件。不过，无论在世界哪个地方实施，都有一些关键原则是一致的：

限制对土壤的干扰.虽然耕作已在农业中广泛使用多年，但这种做法对土壤有机质构成直接威胁，而土壤有机质是土壤肥力和碳储量的关键因素。通过限制对土壤的扰动并引入其他农业实践，如覆盖种植和直接钻探，土壤生态系统可以得到发展并提供关键的生态系统服务。很快，你就能看到土壤侵蚀急剧减少，土壤生物多样性最大化，养分循环能力相应提高，保水性得到改善。  

覆盖土壤。 裸露的土壤，尤其是耕作后的裸露土壤，会大大增加二氧化碳排放量。₂ 土地排放的二氧化碳。阳光照射在裸露的土壤上，会氧化有机物，导致二氧化碳的排放。₂ 这将直接造成肥力损失。采用覆盖作物：在主要轮作之间播种临时作物，是避免土壤裸露的一种经济、自然的方法。覆盖土壤还能防止土壤侵蚀和径流进入水系。

整合牲畜。 从历史上看，牲畜和农作物一直紧密相连。随着集约化方法的过度专业化，许多农场不再饲养牲畜，或将牲畜引入室内系统。动物和植物的分离是生物化学效率低下和二氧化碳排放增加的主要原因。₂ 排放。通过有计划地放牧和施用粪肥，重新整合作物和牲畜，我们可以提高土壤肥力，同时减少对人工杀菌剂、杀虫剂和化肥的需求。

把活根留在地里 健康的根系可以建立土壤的生物多样性，循环养分，帮助土壤保持水分。多年生作物对保持土壤中的活根系统非常有益。然而，集约型农业以一年生作物为主，这些作物不会在地里留下活根，从而破坏了土壤结构和养分水平。将多年生植物重新引入农业系统是重建全年生根系统的快速方法，还能减少疾病，为大自然提供一个家园。

Green finance

These regenerative practices are a return to what some might say is a traditional way of farming, but they also represent a very modern opportunity for farmers. The recent focus on the reduction of greenhouse gas (GHG) emissions and the potential for soils to sequester carbon has lead to the creation of carbon market.  When farmers implement regenerative practises they can sequester and reduce carbon, improve local biodiversity and increase natural capital. These actions, when verified, will give them access to a new source of funding through the Green Finance Market, such as environmental impact bonds and payment for environmental services schemes.
