No results found.Global forests are increasingly threatened by alien invasive pathogens and pests. The magnitude of this threat is expected to further increase in the future, due to the warmer climate and more extensive global transports and trade of plants. Pests and pathogens are often introduced to new areas by trade with ornamental plants as intermediate hosts, and there is a great need to modernize the tools for detection of alien species in imported plants and in monitoring of those that are already established in our forests. To achieve this goal, research in forest pathology is focused on combining recent technological advances in robotics, next generation sequencing, and mass spectroscopic methods with knowledge about the specific metabolic responses in the pests and pathogens and the trees that they infest. Gas Chromatography (GC) Analysis of Volatile Organic Compounds (VOCs) adsorbed on Solid Phase Micro-Extraction (SPME) fibers is one promising method with potential for high-throughput detection of larger plant shipments. By the establishment of a library of chemical fingerprints characterizing specific pests and pathogens, one could non-destructively scan a large number of plants in ports or nurseries to eliminate presence of disease. The species-specific combination of VOCs can be utilized to prevent introduction of harmful pests and pathogens to new markets. One pathogen considered as a quarantine species and a serious threat on-the-horizon for coniferous forests is Pine Pitch Canker (PPC), a fungal pathogen affecting a variety of pine species with devastating economical and biological consequences, especially if it were to be established in a country like Sweden where about 38% of the standing forest volume consist of pine. Pathogens like this one are already introduced in several European countries, and need to be monitored and identified early to prevent further forest damage – a challenge that Forest pathologists have accepted.

No results found.Forest invasive species are non-native pests, pathogens and plants that are introduced either unintentionally or intentionally to an ecosystem, having a significant environmental, economic, and/or socio-cultural impact. FAO is addressing the pressing global issue of invasive species in several ways including: producing publications and other knowledge products (e-learning courses); offering assistance to the countries both in emergency and after-outbreak situations, as well as long-term prevention strategies; and helping to establish and maintain regional networks dedicated to invasive species. Invasive species have no borders, therefore a strong and more coordinated interaction by affected countries within the same region and among different regional forest invasive species networks is needed to provide timely and efficient response when new invasive species are introduced and/or detected in a country or region. The Regional Forest Invasive Species Networks aim to foster the exchange of information and the mobilization of resources, support forest health projects, raise regional awareness, and act as a link between and among experts, institutions, networks and other stakeholders concerned with forest invasive species. The side event to COFO (20-07-2018) on global approach for managing forest invasive species is meant to: enhance Forest Invasive Species Networks regional collaboration; initiate the establishment of a harmonized global approach for management of forest invasive species.

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. -
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. -
