Book (stand-alone)Technical bookStandard operating procedure for soil enzyme activities
β-glucosidases, arylsulfatase, N-acetyl-β-glucosaminidase, dehydrogenase, phosphomonoesterases
2025Also available in:
No results found.This standard operating procedure (SOP) has been harmonized by the joint working group of the FAO's Global Soil Laboratory Network (GLOSOLAN) and the International Network on Soil Biodiversity (NETSOB). The protocol focuses on the determination of five soil enzyme activities: β-Glucosidases, Arylsulfatase, N-acetyl-β-Glucosaminidase, Dehydrogenase, and Phosphomonoesterases. After a general introduction on the importance of soil enzyme as key indicator for soil health and few remarks on the sampling strategies, the determination of each enzyme is presented separately with step-by-step instructions. -
Book (series)Technical studyThe impact of climate variability and extremes on agriculture and food security - An analysis of the evidence and case studies
Background paper for The State of Food Security and Nutrition in the World 2018
2020Also available in:
No results found.Global climate studies show that not only temperatures are increasing and precipitation levels are becoming more varied, all projections indicate these trends will continue. It is therefore imperative that we understand changes in climate over agricultural areas and their impacts on agriculture production and food security. This study presents new analysis on the impact of changing climate on agriculture and food security, by examining the evidence on recent climate variability and extremes over agricultural areas and the impact of these on agriculture and food security. It shows that more countries are exposed to increasing climate variability and extremes and the frequency (the number of years exposed in a five-year period) and intensity (the number of types of climate extremes in a five-year period) of exposure over agricultural areas have increased. The findings of this study are compelling and bring urgency to the fact that climate variability and extremes are proliferating and intensifying and are contributing to a rise in global hunger. The world’s 2.5 billion small-scale farmers, herders, fishers, and forest-dependent people, who derive their food and income from renewable natural resources, are most at risk and affected. Actions to strengthen the resilience of livelihoods and food systems to climate variability and extremes urgently need to be scaled up and accelerated. -
Book (series)Flagship2024年粮食及农业状况
价值驱动农业粮食体系转型
2024揭示膳食的真实成本是打造更包容、更有韧性、更可持续农业粮食体系的第一 步。正如《2023年粮食及农业状况》所述，农业粮食体系活动为社会创造了重大利益， 但也对经济、社会、环境可持续性产生了负面影响。农业粮食体系的隐性成本估计约占全球国内生产总值的10%。因此，采取战略行动至关重要，农业粮食体系中所有行动主体，包括从生产者、农业企业到消费者和政府等，都应发挥关键作用。虽然实现农业粮食体系转型将为全球带来净收益，但转型的收益和成本在各利益相关方和国家之间却难以均匀分配。《2024年粮食及农业状况》基于2023年版的发现，深入探讨如何采用农业粮食体系真实成本核算，确定转型所需的政策干预措施。报告利用经过更新的全球数据库，确认了先前核算的农业粮食体系隐性成本，并详细列出了156个国家与不健康膳食结构和非传染性疾病相关的隐性成本。报告从六种类型农业粮食体系入手开展分析，根据预期结果和隐性成本设计不同的政策干预措施。案例研究便于我们对国家、地方和价值链场景进行深入评估，展示当前做法对经济、社会和环境的影响，为政策干预措施提供指导。在所有场景下，都必须与利益相关方开展包容性协商，以便为干预措施提供依据，并努力调和权力失衡和不同目标之间的利弊取舍。
