The Agriculture, Value Added data set was created by the World Bank and displays the net output of agriculture sectors in most countries and various other regional entities (e.g., geographic regions, economic output, members of certain economic/political unions) after adding up all outputs and subtracting the value of intermediate goods and services consumed in production. Agriculture corresponds to International Standard Industrial Classification (ISIC) divisions 1-5 and includes forestry, hunting, and fishing, as well as cultivation of crops and livestock production. The value added is calculated without making deductions for depreciation of fabricated assets or depletion and degradation of natural resources. The origin of value added is determined by the ISIC, revision 3. National data are available for some countries beginning in 1960 and available for an increasing number of countries up until 2016, when all but a few countries are represented. Resource Watch shows only a subset of the data set. For access to the full data set and additional information, see the Learn More link.
Agriculture, value added (% of GDP)
Among the difficulties faced by compilers of national accounts is the extent of unreported economic activity in the informal or secondary economy. In developing countries a large share of agricultural output is either not exchanged (because it is consumed within the household) or not exchanged for money. Agricultural production often must be estimated indirectly, using a combination of methods involving estimates of inputs, yields, and area under cultivation. This approach sometimes leads to crude approximations that can differ from the true values over time and across crops for reasons other than climate conditions or farming techniques. Similarly, agricultural inputs that cannot easily be allocated to specific outputs are frequently "netted out" using equally crude and ad hoc approximations.
