The image contains a pie chart and a table about land degradation. The pie chart, titled 'Causes of Worldwide Land Degradation', shows the following breakdown: Removing Trees 35%, Farming Animals 30%, Growing Crops 28%, and Other 7%. The table, 'Causes of land degradation by region', details the percentage of land degraded by cause for three regions. Region 1 has a Total Land Degraded of 5%, composed of Removing Trees (0.2), Growing Crops (3.3), and Farming Animals (1.5). Region 2 has a Total Land Degraded of 23%, from Removing Trees (9.8), Growing Crops (7.7), and Farming Animals (5.5). Region 3 has a Total Land Degraded of 13%, made up of Removing Trees (1.7), Growing Crops (0), and Farming Animals (11.3). A footnote defines land degradation as 'the process of reducing the quality of land or soil.'

The chart illustrates the main reasons why the agricultural land becomes less productive. It depicts how these factors affected three regions i.e. North America, Europe and Oceania during the 1990s leading to land degradation.
Over-grazing by cattle accounts for 35% which is the primary cause of land degradation. Followed by deferostation and over-cultivation each accounting for approximate 30% of the land degradation. Other factors contribute to 7% of land becoming unproductive.
Out of all the 3 nations, major land degradation is caused in Europe during the 1990s accounting for 23% of the total land, with deforestation a major contributing factor with 9.8% follwed by over grazing and then the other factor i.e. over degraded.
North America is the least afftected nation with just 5% of land rendered unproductive with over-grazing as the primary reason with 3.3% and deforestation the least contributing factor. On the other hand Oceania had 13% on land degraded with over-degradation as the major contributing factor. Here over grazing does not play the part in land unproductivity.
