Fossil fuel infrastructure has important land-use impacts within the United States, including the environmental consequences of affected land that persists beyond the lifespan of wells. Here, we estimate the ecoregion-specific fifty-year present-value net benefits of restoring lands that are associated with non-producing wells in the conterminous United States on the basis of select ecosystem services—agricultural sales and carbon sequestration. We identify more than 430,000 restorable wells that occupy more than 800,000 ha of land. The present value of ecosystem services benefits was US$21 billion (2018) while the restoration costs were US$7 billion. Deciduous forests, grasslands and Mediterranean ecoregions had large net benefits, whereas arid and semi-arid regions were often negative. Focusing on select ecoregions of the United States would provide higher returns on investment in the form of environmental and economic benefits. Although our results suggest an ecoregional hierarchy, the restoration of all abandoned fossil fuel lands will have benefits at the local, regional and national scales, including food security, protection of biodiversity and restoration-related job opportunities.

生态系统服务得益于美国非生产性油气田的恢复

化石燃料基础设施在美国国内具有重要的土地使用影响,包括受影响的土地对环境的影响持续到井的使用寿命之外。在这里,我们根据特定的生态系统服务(农业销售和碳固存),估算了恢复与美国本土非生产井相关的土地的特定于生态区的五十年现值净收益。我们确定了超过430,000口可修复的井,这些井占用了超过800,000公顷的土地。生态系统服务收益的现值是210亿美元(2018年),而恢复成本是70亿美元。落叶林,草原和地中海生态区具有较大的净收益,而干旱和半干旱地区通常是负面的。将重点放在美国的特定生态区将以环境和经济利益的形式提供更高的投资回报。尽管我们的结果表明存在生态区域等级制度,但所有废弃化石燃料土地的恢复将在地方,区域和国家范围内受益,包括粮食安全,保护生物多样性以及与恢复相关的工作机会。
