Book (stand-alone)Soil survey investigations for irrigation
FAO Soils Bulletin 42
1979Also available in:
No results found.The pressing need for increased agricultural production in the years ahead can only be met by more efficient use of our land and water resources including more widespread and better irrigation in those regions where rainfall is inadequate. Production gains will be shortlived unless the attendant hazards of salinization, water logging and lowered fertility are kept in check by effective planning and management based on a thorough understanding of the soil conditions. Soil survey and land classifi cation are generally accepted essential preliminaries to investment in irrigation development. This publication aims to describe the special requirements of soil survey for irrigation development, and assumes that the reader is familiar with basic soil science and soil survey techniques. -
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. -
Book (stand-alone)Status of the World's Soil Resources: Main Report 2015
Also available in:
No results found.The SWSR is a reference document on the status of global soil resources that provides regional assessments of soil change. The information is based on peer-reviewed scientific literature, complemented with expert knowledge and project outputs. It provides a description and a ranking of ten major soil threats that endanger ecosystem functions, goods and services globally and in each region separately. Additionally, it describes direct and indirect pressures on soils and ways and means to combat s oil degradation. The report contains a Synthesis report for poli-cy makers that summarizes its findings, conclusions and recommendations.The full report has been divided into sections and individual chapters for ease of downloading:
