The pie chart below shows the main reasons why agricultural land becomes less productive. The table shows how these causes affected three regions of the world during the 1990s. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

A glance at the pie chart delineates information about the commensurability of the staple factors degrading land production throughout the world, and the second one, the table, tabulates the statistics of threefold regions from 1990 to 1999.

Overall

, it can explicitly be perceived that over-grazing was known as the universally main reason for the agricultural problems,

while

there were some exceptions for limited areas

such

as North America and Europe where

over-cultivation

and deforestation, respectively, predominated overwhelmingly with respect to the others. Looking into more details for the first illustration, excessive animal grazing had a 35% quota among all causes demolishing worldwide land fertility. As much as a third of

this

proportion was devoted to deforesting. Tertiary ranking allocated to

over-cultivation

, influencing 28 per cent of farmlands. It is noteworthy that other causes could extensively affect

this

universal issue, somewhere in the vicinity of 7%. In terms of the parameters that caused farmland depletion for some regions, decreasing from 9.8% for deforestation to 7.7% for

over-cultivation

23%, the most amount among these three regions. The figure for total land degradation in Australia and New Zealand was 13%, in which over-grazing had the dominant role with a percentage of 11.3, and

over-cultivation

had staggeringly no influence.

This

was followed by North America, 5% of which was demolished in total, where cultivation was inordinately done with a critical amount of 3.3%.
