Greening of China and IndiaNASA

NASA has some good newsThe world is a greener place today than it was 20 years ago. What motivated the change? Well, it seems that China and India can take the majority of the credit.

Contrary to the perception of the will of China and India to overexploit the land, water and resources for economic benefit, countries are responsible for the greatest greening of the planet during of the last two decades. The two most populous countries have implemented ambitious tree planting programs and have stepped up their implementation and their technology around agriculture.

India continues to break world records in tree planting with 800,000 Indians plant 50 million trees in just 24 hours.

The recent discovery of NASA and published in the newspaper Sustainability of nature, compared satellite data from the mid – 90s to today 's using high – resolution images. Initially, the researchers did not know what caused the significant rise in greening around the planet. It was unclear whether global warming, increased carbon dioxide (CO2) emissions or a wetter climate would have allowed more plants to grow.

After further study of satellite images, researchers found that greenery was disproportionately large in China and India. If greening is primarily a response to climate change and global warming, the increase in vegetation should not be limited to the borders of the country. In addition, higher latitude regions are expected to become greener more rapidly than lowland regions as permafrost melts and areas such as northern Russia become more habitable.

The map above shows relative greening (increasing vegetation) and browning (decreasing vegetation) around the globe. As you can see in China and India, greening is important.

The United States is at number 7 of the total change in vegetation per decade. Of course, the table below can hide the starting point of each country. For example, a country that largely retains its intact forests and vegetation will have little leeway to increase the percentage of vegetation, while a country highly dependent on deforestation will have more room for growth.

NASA used Moderate resolution imaging spectroradiometer (MODIS) to obtain a detailed picture of the global vegetation of the Earth through time. The technique has provided a resolution of up to 500 meters in the last two decades.

China and India went through large-scale deforestation in the 1970s and 1980s, clearing ancient forests for urban development, agriculture and agriculture. However, it is clear that, faced with a problem, humans are incredibly good at finding a solution. When the focus was put in the 1990s on reducing air and soil pollution and combating climate change, both countries have significantly changed their land use.

It is encouraging to see a rapid and rapid change in governance and land use when the dilemma is presented. It is something that will continue to be a necessary skill in the coming decades.
