DocumentOther documentCalibration and validation techniques development for forest utilization of agroforestry satellite data
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The Agriculture and Forestry Satellite, one of the next-generation medium-sized satellite series to be launched in Korea, is a satellite in progress to monitor environmental changes in forestry and agriculture and periodic monitoring of forests and crops. It has five spectral bands, including Blue, Green, Red, Red Edge, Near Infrared, and a high spatial resolution of 5 m. It is designed to observe the entire Korean peninsula in 3 days by utilizing a revisit cycle once a day and a wide swath of 120 km. To accurately collect surface information from the satellite images, it is necessary to correct the geometry and topography effects. Because geometry and topography correction is significant because the reflectivity may appear different depending on the slope. Therefore, it is necessary to analyze what parameters respond sensitively to the wavelength range of agricultural and forestry satellites in Korea's forest areas and how they affect them. Since the current agriculture and forestry satellite is before launch, we will use similar satellite images to examine the pre-launch image calibration and validation technology. This presentation intends to share the analysis's initial results by applying geometric, and terrain correction techniques using currently available satellites similar to agroforestry satellites. Through this study's results, it is expected that it will be able to provide factors to be considered in the forestry field in the future development of the agricultural and forestry satellite calibration program.

BookletCorporate general interestEstablish validated critical limits – Step 8, Principle 3 2023
Also available in:
Hazard analysis and critical control point (HACCP) consists of seven principles and is typically described in 12 successive steps. This guidance document provides information on how to set and validate critical limits for each Critical control point (CCP) (Step 8 / Principle 3) to develop an effective HACCP system in accordance with the Codex Alimentarius General Principles of Food Hygiene (CXC 1-1969). Critical limits establish whether a CCP is in control, and can, therefore, be used to separate acceptable products from unacceptable ones. Critical limits should be measurable or observable and typically use minimum and/or maximum values or critical parameters, such as temperature, time, moisture level, pH, aw, conveyor belt speed, etc. Critical limits should be scientifically validated to ensure they are capable of controlling hazards to an acceptable level. In many cases, CCPs can be validated using available information and existing studies from credible sources. This publication is part of the FAO Good Hygiene Practices (GHP) and Hazard Analysis and Critical Control Point (HACCP) Toolbox for Food Safety series. The toolbox is a central repository of practical guidance and resource materials to strengthen food safety capacities, both public and private, in order to develop and implement food safety management programmes in accordance with the Codex standards. Care was taken to consider the challenges faced by small food business operators and primary producers in low- and middle-income countries, and those with an institutional role, such as government officials, academia and capacity building organizations.

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -
DocumentManual / guideReference Manual, Chapter 3 – AquaCrop, Version 7.0 – August 2022 2016
Also available in:
No results found.AquaCrop is a general model, in that it is meant for a wide range of herbaceous crops, including forage, vegetable, grain, fruit, oil, and root and tuber crops. Chapter 3 presents the software of AquaCrop for which: the concepts and underlying principles are described by Steduto et al. (2009); the structure and algorithm are found in Raes et al. (2009), and the parameterization for maize (the crop on which the efforts of parameterization were focused during the early phase of model development) are reported by Hsiao et al. (2009). Examples of crop development and production for specific climate and growing conditions estimated by AquaCrop are given in a lot of papers published in peer reviewed journals. A digital library of references to all AquaCrop publications can be found on: https://www.zotero.org/groups/aquacrop_publications. -
BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.
