FAO Statistical yearbook 2013. World food and agriculture
The 2013 edition of FAO's Statistical Yearbook explains agriculture's contribution to global warming, trends in hunger and malnutrition and the state of the natural resource base upon which world food production depends.
The report indicates that greenhouse gas emissions from agriculture grew 1.6 percent per year during the decade after the year 2000, with the sector's total annual output in 2010 reaching 5 billion tons of carbon dioxide equivalents (CO2 eq, a measure used to compare and aggregate different greenhouse gases). This equals 10 percent of all anthropogenic greenhouse gas emissions.
The newly added GHG database offers a complete time-series of emission statistics for all countries over the period 1990-2010. The report aims to help countries to identify, assess and report GHG emissions from their agriculture, forestry and other land use sectors, as part of the activity data they already report to FAO.
Using the methodology for GHG reporting, developed by the Intergovernmental Panel on Climate Change. Progress, the emissions estimates are computed from FAOSTAT activity data which is peer reviewed by experts at FAO and around the world. The GHG data are now open to the public, facilitating feedback from countries.
Among the various agriculture sectors, livestock activities and the use of synthetic fertilizer are the largest contributors. This does not include emissions caused by land use change and wild fires.
The report includes different topics such as: capital and investment; climate change; food availability; food production and trade; food prices; hunger and malnutrition; the consequences of political instability and natural- and human-induced disasters on food security; the state of the agricultural resource base and sustainability and environmental impacts.
