India, China leading global greening effort: NASA study : Economic Times
India and China are leading the global greening effort, which is quite contrary to the general perception worldwide, a latest NASA study said 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 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.
"That is a surprising finding, considering the general notion of land degradation in populous countries from over exploitation," he said.
The study published on February 11, in the Nature Sustainability journal said that recent satellite data (2000–2017) reveal a greening pattern that is strikingly prominent in China and India and overlaps with croplands world-wide.
