Book (stand-alone)Technical bookStatus of the World’s Soil Resources. Chapter 7: The impact of soil change on ecosystem services 2016
Also available in:
No results found.This is Chapter 7, "The impact of soil change on ecosystem services," of the report Status of the World’s Soil Resources.Soils are now recognized to be in the ‘front line’ of global environmental change and we need to be able to predict how they will respond to changing climate, vegetation, erosion and pollution. Although only a thin layer of material at the Earth’s surface, soils like many interfaces play a pivotal role in regulating t he flow and transfer of mass and energy between the atmosphere, biosphere, hydrosphere and lithosphere. Soils help regulate the Earth’s physical processes such as water and energy balances, and act as the biogeochemical engine at the heart of many of the Earth system cycles and processes on which life depends. All these phenomena are discussed in this chapter.

Book (stand-alone)Technical bookStatus of the World's Soil Resources. Chapter 3: Global Soil Resources 2016
Also available in:
No results found.This is Chapter 3, "Global Soil Resources," of the report Status of the World’s Soil Resources. Soil functions depend on a number of physical, chemical and biological soil properties that in combination determine essential soil qualities. These qualities in turn guarantee that the soil can fulfil its ecological and productive services. Soils differ considerably in terms of properties, qualities, limitations and potential. Significant change s may occur over very short distances, making environmental and soil monitoring difficult. Soil management has a considerable effect on how the soil may fulfil its ecosystem services. In this section a number of soil qualities essential for the provision of ecosystem services are discussed. In addition a history is traced of global assessments of soil and land degradation.The full report has been divided into sections and individual chapters for ease of downloading:

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2023
Urbanization, agrifood systems transformation and healthy diets across the rural–urban continuum
2023This report provides an update on global progress towards the targets of ending hunger (SDG Target 2.1) and all forms of malnutrition (SDG Target 2.2) and estimates on the number of people who are unable to afford a healthy diet. Since its 2017 edition, this report has repeatedly highlighted that the intensification and interaction of conflict, climate extremes and economic slowdowns and downturns, combined with highly unaffordable nutritious foods and growing inequality, are pushing us off track to meet the SDG 2 targets. However, other important megatrends must also be factored into the analysis to fully understand the challenges and opportunities for meeting the SDG 2 targets. One such megatrend, and the focus of this year’s report, is urbanization. New evidence shows that food purchases in some countries are no longer high only among urban households but also among rural households. Consumption of highly processed foods is also increasing in peri-urban and rural areas of some countries. These changes are affecting people’s food security and nutrition in ways that differ depending on where they live across the rural–urban continuum. This timely and relevant theme is aligned with the United Nations General Assembly-endorsed New Urban Agenda, and the report provides recommendations on the policies, investments and actions needed to address the challenges of agrifood systems transformation under urbanization and to enable opportunities for ensuring access to affordable healthy diets for everyone. -
Book (stand-alone)Technical bookClimate change and food security: risks and responses 2015
Also available in:
End hunger, achieve food security and improve nutrition are at the heart of the sustainable development goals. The World has committed to eradicate extreme poverty and hunger by 2030. But climate change is undermining the livelihoods and food security of the rural poor, who constitute almost 80 percent of the world’s poor. The effects of climate change on our ecosystems are already severe and widespread. Climate change brings a cascade of impacts from agroecosystems to livelihoods. Climate change impacts directly agroecosystems, which in turn has a potential impact on agricultural production, which drives economic and social impacts, which impact livelihoods. In other words, impacts translate from climate to the environment, to the productive sphere, to economic and social dimensions. Therefore, ensuring food security in the face of climate change is among the most daunting challenges facing humankind. Action is urgently needed now to reduce vulnerability and increase resilience of food systems to ensure food security and good nutrition for all. -
DocumentOther documentReducing inequalities for food security and nutrition
A report by the High Level Panel of Experts on Food Security and Nutrition
2023The report “Reducing inequalities for food security and nutrition” has been developed by the High Level Panel of Experts on Food Security and Nutrition (HLPE-FSN) following the request by the United Nations Committee on World Food Security (CFS) as included in its Programme of Work (MYPoW 2020-2023). In particular, the CFS requested the HLPE-FSN to develop a report to: (i) analyse evidence relating to how inequalities in access to assets (particularly land, other natural resources and finance) and in incomes within food systems impede opportunities for many actors to overcome food insecurity and malnutrition; (ii) analyse the drivers of inequalities and provide recommendations on entry points to address these; and (iii) identify areas requiring further research and data collection. This report will inform the ensuing CFS thematic workstream on inequalities, aiming at addressing the root causes of food insecurity with a focus on those “most affected by hunger and malnutrition”.
