Washington: India and China are leading the global greening effort, which is quite contrary to the general perception worldwide, a latest NASA study said on Monday, observing that the world is a greener place than it was 20 years ago. The NASA study based on data received and analysed from its satellite said that India and China are leading in greening on land. “China and India account for one-third of the greening but contain only 9 per cent of the planet's land area covered in vegetation,” said lead author Chi Chen of Boston University.
The study published on February 11, in the journal Nature Sustainability said that recent satellite data reveal a greening pattern that is strikingly prominent in China and India and overlaps with croplands world-wide. China alone accounts for 25 per cent of the global net increase in leaf area with only 6.6 per cent of global vegetated area.
The greening in China is from forests (42 per cent) and croplands (32 per cent), but in India it is mostly from croplands (82 percent) with minor contribution from forests (4.4 per cent).
Food production in China and India has increased by over 35 per cent since 2000 mostly owing to an increase in harvested area through multiple cropping facilitated by fertiliser use and surface- and/or groundwater irrigation. Rama Nemani, a research scientist at NASA's Ames Research Center and a co-author of the study said in the 1970s and 80s in India and China, the situation around vegetation loss was not good.
In the 1990s, people realized it, and today things have improved.
