According to a report India and China who are two of the biggest contributors to pollution are now turning leafier. This greening effect has its roots from the intensive plantation programs on China and extensive farming in both the countries. As compared to the earlier report in the 2000s, there has been an increase of 5%, which is approximately 2 million square miles per year.
This increase in foliage will result in slowing down the climatic change but there might be an overall rise in temperature.
According to the space agencies in US show that in the last 20 years there has been a considerable increase in the leafy areas, which is estimated to be as big as the Amazon rainforests. This phenomenon was first sighted in the 1990s. Back then the scientists had assumed that this was due to the increase in the level of CO2 in the atmosphere that resulted in increased fertilization resulting in this effect.
With the help of Modis, an instrument developed by NASA, scientists can now conclude that this is mainly due to extensive farming and plantation programs. China has the larger share in the greening program (approximately 42%), due to its programs to eradicate soil erosion and climatic change problems.
Along with this India holds a share of 42%, primarily due to its food crop cultivation programs resulting from an increase in the use of fertilizers and pesticides.
There has been a 35 to 40% increase in cultivation since the early 2000s to provide for the large population of both the nations.
In future the numbers for India are predicted to fall, due to shortage in groundwater irrigation. Globally scientists are warning a record level increase in the CO2 levels due to the heating in the Pacific region, which is expected to cause a reduction in the intake of CO2 in plants.
