[马尼拉]健康的土壤对于从粮食不安全到气候变化的全球挑战至关重要,但是需要更多数据来解锁这些基于自然的解决方案。新报告由联合国食品和农业组织(FAO)发行。

该报告包括来自世界各地300多家科学家的输入,并定义了土壤biodiversity从地下生命的多样性,从基因和物种到它们形成的社区,以及它们所贡献的生态综合体以及它们所属的生态综合体。

“土壤生物多样性代表了地球总生物多样性的25%,但我们只知道它的百分之大约1%”

“土壤生物多样性代表了地球总生物多样性的25%,但我们只知道它的百分之大约1%。”全球的Soil Partnership,由支持粮农组织,告诉scidev.net

土壤生物多样性是实现许多可持续发展目标该报告认为,但其贡献仍然被低估了。尽管没有可持续发展目标直接指土壤,但其中许多,例如18beplay ,,,,18beplay官网 缺乏,climate change,生物多样性损失和健康threats are closely linked to or dependent on soil biodiversity.

瓦尔加斯指出:“我们对土壤生物多样性的了解不多,但它的损失是由于人类实践不可持续的。”

The report, published 5 December, points todeforestation并将其作为对土壤生物多样性的最大总体威胁,从而在拉丁美洲和加勒比海地区和加勒比海地区的植被组成发生了巨大变化,以及在撒哈拉以南非洲的热带和亚热带草地中重要的土壤有机碳的相关损失。

Meanwhile, across the Southwest Pacific, which includes the Small Island Developing States,农业强化和入侵物种是对土壤生物多样性的主要威胁。在亚洲,土壤生物多样性的地位差异很大,气候变化会带来新的威胁,影响高地和沿海地区。其他主要威胁包括城市化,污染and salinisation.

Threats to soil biodiversity are alarming given their potential applications, says Vargas. “It can help us in agriculture in order to produce with less agrochemicals (synthetic fertilisers and pesticides), it helps us to have safe food, it is crucial for bioremediation of polluted soils, its role in human health is substantive, also in climate change — its potential is huge,” says Vargas.

Rainer Baritz, a soil expert at the欧洲环境局beplay足球体育的微博,告诉scidev.net: “This assessment is an up-to-date treasure of knowledge. It is particularly timely and needed because there is still no systematic soil biological monitoring anywhere in the world.”

“Generally, there is a lack of detailed data,policies以及对地方,国家,地区和全球水平的土壤生物多样性的行动。”粮农组织的媒体发布。它说该报告强调了促进的必要创新的技术in soil management such as next-generation molecular sequencing to enhance understanding of soil organisms and their potential effects on cropping systems.

According to Vargas, few countries in the world collect soil biodiversity data and information. “That limits the perspective and gives us a call,” he says. “How can we manage what we do not know? We need to invest in evidence and that includes soil biodiversity as part of the soil surveys and national information systems.”
