Book (stand-alone)Technical bookFRA 2000: A concept and strategy for ecological zoning for the global Forest Resources Assessment 2000 2002
Also available in:
No results found.A global ecological zoning (EZ) map is needed for carrying out the "Global Forest Resources Assessment 2000" (FRA 2000) presently being facilitated by the United Nations Food and Agriculture Organization. The underlying strategy for FRA’s ecological zoning closely reflects both the thematic and technical requirements of the map, and the many operational constraints for implementation. Characteristics and components of the FAO EZ classification include the use of the Köppen system (1931) as a bas is for the delineation of zones. Details of the Köppen system, along with comparisons to other global-level ecological schemes demonstrate the rationale behind the FRA approach (Table 1). The mapping work will be carried out principally using regional or national "potential vegetation" maps to define boundaries of ecological zones at the global level. Although using a variety of map inputs inevitably provokes methodological problems such as edge matching across adjacent maps, a protocol for co rrecting such problems was successfully developed and implemented during a pilot study. The results of the North America Pilot Study illustrate the overall concept, methods, and utility of the map in an operational context (Annex A). -

No results found.A global ecological zoning (GEZ) map and database has been developed for the “Global Forest Resources Assessment 2000” (FRA 2000) conducted by the United Nations Food and Agriculture Organization. The underlying strategy for FRA’s ecological zoning closely reflects both the thematic and technical requirements of the map and the many operational constraints for implementation. Characteristics and components of the FAO EZ classification include the use of the Köppen-Trewartha system (1968), with s ome modifications, in combination with vegetation characteristics as a basis for the delineation of zones. A key event in the development of the map was the Cambridge expert consultation, July 1999, where the concepts and proposed classification system were discussed, amendments made and a final classification system adopted. The GEZ classification system has a hierarchic structure: at the broadest level 5 domains are distinguished and at the second level 20 global Ecological Zones. The mapping work was carried out principally using regional or national “potential vegetation” maps to define boundaries of Ecological Zones at the global level. Regional experts and scientists provided support and advice. Although using a variety of map inputs inevitably provoked methodological problems such as edge matching across adjacent maps, a protocol for correcting such problems was successfully developed and implemented. In addition to the global EZ map regional descriptions were prepared on vegeta tion, climate and physiography of the Ecological Zones. The report is divided into three sections: • Part I presents the GEZ classification framework; • Part II explains how the map was developed; and • Part III contains the descriptions of the GEZ for each region. -

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. -
BookletCorporate general interestAgrifood solutions to climate change
FAO's work to tackle the climate crisis
2023Amid a worsening climate crisis and slow progress in cutting greenhouse gases, sustainable agrifood systems practices can help countries and communities to adapt, build resilience and mitigate emissions, ensuring food security and nutrition for a growing global population. FAO is working with countries and partners from government to community level to simultaneously address the challenges of food security, climate change and biodiversity loss.But none of this will ultimately succeed unless the world commits to a significant increase in the quality and quantity of climate finance. -
