Book (stand-alone)Global status of black soils 2022
Also available in:
No results found.Black soils are carbon-rich and highly fertile soils known as the world's food basket due to the variability of crops they sustain. For decades, these fertile soils have been widely cultivated and have played a key role in global agricultural production of cereals, tuber crops, oilseed, pastures, and forage systems. In addition, black soils play an important role on climate change mitigation and adaptation. However, this black treasure is under threat. Because of land use change from natural grasslands to cropping systems, unsustainable management practices and excessive use of agrochemicals, most of the black soils have lost half of their soil organic carbon stocks and suffer from moderate to severe erosion processes, as well as nutrient imbalances, acidification, compaction and soil biodiversity loss. FAO and its Global Soil Partnership are committed to the conservation and sustainable management of black soils and established the International Network of Black Soils. This report provides strategic information about the distribution, state and management of black soils and can guide decision-making regarding the sustainable management and conservation of black soils. One of the main recommendation of this report is the establishment of a global agreement for the sustainable management (for conservation, protection and production) of black soils. Sustainable management of black soils contributes to the Sustainable Development Goals (SDGs), particularly the SDG 1 (No poverty), SDG 2 (Zero hunger), along with other SDGs such as SDG 13 (Climate Action), SDG 15 (Land degradation neutrality), and SDG 17 (Partnerships for the Goals). It is also aligned with the four betters of the FAO Strategic Framework 2022-2031: better production, better nutrition, better environment, and a better life, leaving no one behind. -
BookletCountry guidelines and technical specifications for global soil nutrient and nutrient budget maps
GSNmap: Phase 1
2022Also available in:
No results found.The "Country Guidelines provides guidance and technical specifications for the first phase of the GSNmap initiative which aims to generate national maps of soil nutrients and associated soil properties at 250 m resolution for agricultural lands based on a country–driven approach. On the one hand, soil nutrient maps will provide a baseline for identifying areas where their levels are critical for crop growth and will thus serve as an important decision–making tool. On the other hand, associated soil parameters such as organic carbon, pH, soil texture, bulk density, and cation exchange capacity will be mapped, which can highlight the key limits to nutrient availability. In order to obtain consistent results and to allow comparisons between countries and regions, we propose a standard methodology based on digital soil mapping techniques. General modelling procedures, data requirements and data sources are described. The final product specifications and data submission formats are also provided. The final product will be relevant to identify the level of nutrients and associated soil properties per regions, environments and agricultural systems, and to establish priorities for the implementation of global and national public and private policies. -
Book (stand-alone)Global Soil Organic Carbon Sequestration Potential Map – GSOCseq v.1.1
Technical report
2022Also available in:
No results found.This document presents the technical details of the first ever country-driven Global Soil Organic Carbon Sequestration Potential Map (GSOCseq). This map allows for the estimation of top (0–30 cm) soil organic carbon sequestration potential in agricultural areas under a business as usual and three sustainable soil management scenarios. The Global Soil Organic Carbon Sequestration Potential Map (GSOCseq) stands out as a game-changing program aimed at bridging this divide by raising technical expertise on SOC sequestration potential modeling and mapping while relying on a uniquely participatory and iterative process. The GSOCseq v1.1 was developed based on the submissions of national experts appointed by the Food and Agriculture Organization of the United Nations (FAO) Member Nations. Each of the appointed National Experts generated national maps following a bottom-up approach that was facilitated and coordinated by the Secretariat of FAO’s Global Soil Partnership (GSP).
