The given data represents the main reason why agricultural land becomes less productive. In 1990's percentage of land degraded by Europe was 23% which was highest and North America at the lowest with 5%.
According to the given data, over grazing contributes with the largest percentage (35%) which is one of the main causes of worldwide land degradation, where factors like over cultivation and deforestation have also added 25-30% of degradation of land. There are some other minor man-made factors which have resulted in causing degradation.
Interestingly, the table provided shows the causes of land degradation by region. Europeans contribute a major amount of degradation in deforestation (9.8%) and over cultivation with 7.7% while deforestation in North America is the lowest. From these three regions, over grazing is highest in Oceania (11.3%) while other two regions range from 1-6%. For future generations these regions should cut their percentage of land degradation and should start working on making their land more productive.
