BookletCropland nutrient budget
Global, regional and country trends, 1961–2020
2022Also available in:
No results found.The FAOSTAT domain “Cropland Nutrient Budget” disseminates nutrient flows in a given country and year. The Cropland nutrient budget can give an indication of nutrient use efficiency, as it can help quantify excess nitrogen leading to environmental risks, for instance, GHG emissions or pollution from volatilization and leaching/runoff. It can also signal cropland nutrient deficits that limit crop production. The FAO 2022 update of the cropland nutrient budget is a joint effort with the International Fertilizer Association (IFA) in collaboration with University of Maryland, Swedish Agricultural University, University of Madrid, Wageningen University, University of Nebraska and the African Plant Nutrition Institute. This brief analyzes global, regional and country trends for the period 1961–2020. -
BookletSoil nutrient budget
Global, regional and country trends 1961–2018
2021Also available in:
No results found.The FAOSTAT domain “Soil nutrient budget” disseminates nutrient flows in a given country and year. The soil nutrient budget can give an indication of nutrient use efficiency, as it can help quantify excess nitrogen leading to environmental risks, for instance, GHG emissions or pollution from volatilization and leaching/runoff. It can also signal soil nutrient deficits that limit crop production. This analytical brief focuses on the nutrient nitrogen. Nutrient budgets are presented both as total nutrient flows and per area of cropland. Global and regional trends are analyzed along with highlights of the most important contributors to the overall budget and how these main contributors have changed over time. Lastly, the top 10 countries for the soil nutrient budget per unit area and bottom 10 countries for the soil nutrient budget total are presented. -
Book (stand-alone)Nutrient flows and associated environmental impacts in livestock supply chains. Guidelines for assessment
Version 1
2018Also available in:
No results found.The aim of the methodology developed in these guidelines is to introduce a harmonized international approach assessing nutrient flows and impact assessment for eutrophication and acidification for livestock supply chains taking the specificity of the various production systems involved into consideration. The methodology strives to increase understanding of nutrient use efficiency and associated environmental impacts and to facilitate the improvement of livestock systems’ environmental performance. The guidelines are a product of the Livestock Environmental Assessment and Performance (LEAP) Partnership, a multi-stakeholder initiative whose goal is to improve the environmental sustainability of livestock sector through better metrics and data. Nutrient use in livestock production systems increased over the last decades due to the increased demand for livestock production. This demand is mainly driven by the increase in the population growth, population income, and urbanization. Consequently, in livestock supply chains, nutrient losses into the environment have contributed to environmental burdens such as climate change, air and water pollution, degradation of soil quality, loss of biodiversity and human health issues. Therefore, there is strong interest in measuring nutrient flows to improve the environmental performance of the livestock sector. The objectives of these guidelines are: • To develop a harmonized, science-based approach resting on a consensus among the sector’s stakeholders; • To recommend a scientific, but at the same time practical, an approach that builds on existing or developing methodologies; • To promote a harmonised approach to assess nutrient flows and impact assessment, relevant for global livestock supply chains; • To identify the principal areas where ambiguity or differing views exist concerning the methodological framework. During the development process, these guidelines were submitted for technical review and public review. The purpose is to strengthen the advice provided and ensure it meets the needs of those seeking to improve nutrient use efficiency and environmental performance through sound assessment practice. This document is not intended to remain static. It will be updated and improved as the sector evolves and more stakeholders become involved in the LEAP, and as new methodological frameworks and data become available. The guidelines developed by the LEAP Partnership gain strength because they represent a multi-actor coordinated cross-sectoral and international effort to harmonize assessment approaches. Ideally, the harmonization leads to greater understanding, transparent application and communication of metrics, and, not least, real and measurable improvement in environmental performance.
