Drainage of peatlands causes severe environmental damage, including high greenhouse gas emissions. Peatland rewetting substantially lowers these emissions. After rewetting, paludiculture (i.e. agriculture and forestry on wet peatlands) is a promising land use option. In Northeast Germany (291,361 ha of peatland) a multi-stakeholder discussion process about the implementation of paludiculture took place in 2016/2017. Currently, 57% of the peatland area is used for agriculture (7% as arable land, 50% as permanent grassland), causing greenhouse gas emissions of 4.5 Mt CO2eq a−1. By rewetting and implementing paludiculture, up to 3 Mt CO2eq a−1 from peat soils could be avoided. To safeguard interests of both nature conservation and agriculture, the different types of paludiculture were grouped into ‘cropping paludiculture’ and ‘permanent grassland paludiculture’. Based on land legislation and plans, a paludiculture land classification was developed. On 52% (85,468 ha) of the agriculturally used peatlands any type of paludiculture may be implemented. On 30% (49,929 ha), both cropping and permanent grassland paludiculture types are possible depending on administrative check. On 17% (28,827 ha), nature conservation restrictions allow only permanent grassland paludiculture. We recommend using this planning approach in all regions with high greenhouse gas emissions from drained peatlands to avoid land use conflicts.

通过在湿润的泥炭地上土地利用来缓解气候变化–德国东北部古生物学的跨部门空间规划

泥炭地的排水造成严重的环境破坏,包括高温室气体排放。泥炭地重新润湿可大大降低这些排放。重新湿润后,古土壤(即湿的泥炭地上的农业和林业)是一种有前途的土地利用选择。在德国东北部(泥炭地291,361公顷),2016/2017年进行了有关利益相关者的关于古生物学的实施的讨论过程。目前,泥炭地面积的57%用于农业(7%为可耕地,50%为永久草地),造成4.5 Mt CO 2 eq a -1的温室气体排放。通过重新润湿和实施古土壤养殖,最高可达到3 Mt CO 2 eq a -1避免从泥炭土中吸取。为了维护自然保护和农业的利益,将古土壤的不同类型分为“种植古土壤”和“永久草原古土壤”。根据土地立法和计划,制定了古土壤分类法。在52%(85,468公顷)的农业用泥炭地上,可以实施任何类型的古土壤养殖。在30%(49,929公顷)的土地上,取决于行政检查,可以同时种植作物和永久草地古生物。在17%(28,827公顷)的土地上,自然保护限制仅允许永久性的草地古生物学。我们建议在所有从排水的泥炭地排放高温室气体的地区都使用这种规划方法,以避免土地使用冲突。
