美国农业部(U.S. Department of Agriculture)于7月31日发布题为“农林业温室气流的量化:实体规模储量计量法”(Quantifying Greenhouse Gas Fluxes in Agriculture and Forestry: Methods for Entity-Scale Inventory)的报告,介绍如何采取统一的科学方法计量温室气体排放和二氧化碳存储因土地管理和环保活动产生的变化,为培养健康的抗旱土壤提供了新的测量工具。
美国农业部说,这份报告有助于对涉及温室气体的环保项目进行评估,为美国土地所有者加入新兴的碳市场开发新的工具并改进现有的工具。
美国农业部负责自然资源和环境的副部长(Under Secretary for Natural Resources and Environment)罗伯特·邦尼(Robert Bonnie)说,“美国的农牧场和森林管理人员承担保护土地的工作,长期以来认识到管理土壤质量、作物产出能力和动物营养具有的重要意义。保护工作和其他管理方面的变化可以降低温室气体排放,增加碳储存,同时改进土壤的质量和生产力以及抗击干旱等极端天气的适应能力。
报告介绍了为地方农牧场和森林管理工作测量温室气体排放和碳储存变化提供的有科学根据的方法,可用于培养健康和高碳土壤,提高粮食、纤维和燃料生产的适应能力。
这份报告由38位农田、牧场、牲畜和林业管理领域的学术和政府专家参加撰写并由另29位科学家、联邦专家和公众进行评议,现刊登在美国农业部网站上。
这是欧巴马政府从多方面为缓和和适应气候变化采取措施的又一个例证。

The U.S. Department of Agriculture (USDA) is offering new tools to gauge progress in building drought-resistant, healthy soil.
A report released July 31 provides uniform scientific methods for quantifying the changes in greenhouse gas emissions and carbon dioxide storage from various land management and conservation activities.
USDA
says the report,
“America’s farm, ranch and forest managers are stewards of the land, and have long recognized the significance of managing soil health, plant productivity and animal nutrition,” Under Secretary for Natural Resources and Environment Robert Bonnie said. “Conservation practices and other management changes can reduce GHG emissions and increase carbon storage while improving soil health, productivity, and resilience to drought and other extreme weather.”
The report outlines science-based methods for quantifying changes in greenhouse gas emissions and carbon storage at the local farm, ranch or forest operation. Those methods will provide tools to build healthy, carbon-rich soils and more resilient production of food, fiber and fuel.
The
It is another example of the Obama administration’s multifaceted approach to climate change mitigation and adaptation.
