    健康的土壤是满足粮食、生物质(能源)、纤维、饲料等产品不同需要的基本前提, 并确保在世界所有区域提供必要的生态系统服务。然而,人类正面临着前所未有的土 壤资源压力。特别是,各种类型的土地退化,包括快速城市化造成的土壤板结正在招 致沉重的代价,威胁着粮食安全和生态平衡。考虑到目前处于审议阶段并很快付诸实 施的可持续发展目标,必须从根本上保证土壤的可持续管理,才能让这些目标变为现 实

    土壤是植物赖以生长的基础 对植物进行栽培和管理可促进饲料、纤维、燃料和药材生产 2015
    健康的土壤对于确保自然和栽 培植物的可持续生长,提供饲 料、纤维、燃料、药材,以及 气候调节和氧气等其他生态系 统服务都有至关重要的作用。土壤和植物相互 依存。肥沃的土壤通过为植物提供氧分并发挥 蓄水池和固根基质的作用,促进植物的生长。 反过来,植物、树木覆盖和森林则通过稳定土 壤、维持水分和养分循环以及减少水蚀和风 蚀来防止土壤退化和荒漠化。随着全球经济增 长和人口变化,对植物、动物饲料和木材等植 物副产品的需求不断增加,给土壤造成巨大的 压力,退化危险与日俱增。植物的可持续管理 — 无论是在森林、牧场还是草原 — 将有助于加 强它们所产生的惠益,包括木材、饲料和食物, 在某种程度上满足社会的需求,同时为当代和子 孙后代的利益维护土壤。

    What will be needed to realize the vision of a world free from hunger and malnutrition? After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021.

    The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.
