Rates of reduction in South Asia have been the most dramatic; per capita land use in was roughly one-third of its value in The visualisation shows the change in the average agricultural land use which is the sum of cropland and grazing area per person over the long-term since 10, BC , measured in hectares per person.

If we extend our land coverage above from arable land use to total agricultural land which is the sum of arable, permanent crops and pastures and meadows , we still see overall declines in land per person but with different rates and patterns of reduction.

Overall, we see that agricultural land per person is higher than that of arable land. At the global level, per capita agricultural land use is now less than half its value in Africa in particular has seen dramatic reductions in agricultural land per person — now less than one-third of per capita land 50 years ago. The Americas North and South and Africa have notably higher per capita agricultural land use relative to Europe and Asia.

In the chart here we see the global area of land use in agriculture by major crop types, from to Overall, we see that the majority of our arable land is used for cereal production; this has grown from around to million hectares an area roughly twice the size of Germany over this period. The total land area used for coarse grains has remained approximately constant over this 50 year period, and is the 2nd largest user of arable land.

The most dramatic increase in land allocation is in the production of oilcrops. Total land area used for oilcrop production has increased almost 3-fold since — an area just short of the size of Mexico. All other crop types take up less than million hectares of global area. The amount of land required to produce food has wide variations depending on the product—this is especially true when differentiating crops and animal products.

At the bottom of the scale, we see that cereal crops typically have a small land impact per unit of protein although such protein is often lacking in some essential amino acids.

At the upper end of the spectrum we find meat products, with the land required for beef or mutton up to times larger than cereals. This means individuals can make notable reductions in the environmental impact of their diets simply by substituting lower-impact meat products for beef or mutton. This visualization shows the index of the arable land area needed to produce an equivalent aggregate of crop production, relative to the land area needed in i.

For example, globally in , the index value was 0. The crop production index PIN is the sum of crop commodities produced after deductions of quantities used as seed and feed. It is weighted by the commodity prices. The idea for this chart is taken from Ausubel, Wernick, and Waggoner Countering the global rise of population and affluence by parents and workers, consumers and farmers restrained the expansion of arable land by changing tastes and lifting yields.

The noticeable shrinkage in the extent of cropland as a function of the Crop Production index since provides encouragement that farmers will continue sparing land. The following discussions on global land use particularly in relation to agriculture cover a number of definitions and combined categories. To provide some clarity on the definitions used here and the common terminology within the literature we have visualised these land use categories and groupings in the chart shown here.

Mixed farms are also commonly found in the UK because these are more economically feasible. If crops do not perform well one season, the income from animals can make up for the loss. In addition, animals also provide good amount of manure for crops.

Based on the use of farm products, farming can also be categorised as subsistence and commercial. Based on the input involved and techniques used in farming, there are two more subcategories of farming.

Most of the farming in the UK is intensive but some areas of Scotland and Wales also come under extensive farming. The more fertilethe soil is, the more arable. Enacting new policies likeputting a tax on products that ultimately lead to the degradationof arable land and poor land use. Agricultural income refers to income earned or revenue derived from sources that include farming land , buildings on or identified with an agricultural land and commercial produce from ahorticultural land.

Agricultural income is defined under section 2 1A of the Income Tax Act, Asked by: Aivaras Doigner business and finance environmental services industry What is the difference between arable land and agricultural land? Last Updated: 2nd June, Agricultural land is defined as the land area that is either arable , under permanent crops, or underpermanent pastures. Arable land includes land undertemporary crops such as cereals, temporary meadows for mowing orfor pasture, land under market or kitchen gardens, and land temporarily fallow.
