No trade offs in food security, in fact the tree planting that India and 24 countries have started with the "Middle East Green Initiative" will actually increase the amount of farmlands, that can be created when replanting arid areas that formerly had grassland-savannah like the THAR desert.

A more important impact of the tree planting, will be the increase of rainfall, especially if the local "rain trees" are replanted that create the "Cloud forests" where rainclouds are formed from the Pseudomonas bacteria living on the host plant leaves.

India is about to start replanting millions to billions of trees, to sequester carbon, according to what was said at the COP27 meeting a year ago by your Minister of the Environment, Forest and Climate Change.

That is a very important issue that scientists in India need to discover, which are India's "rain trees", so more can be planted to help extend the monsoonal moisture during the rainy season move further westward and more quickly. The lack of the "rain trees" on the east coast and center of India, makes the monsoon struggle to move from east to west every year.

India has the perfect Cloud forests to study, in the Western Ghats, which produce new rain clouds all of the time, but they are wasted as they fly westward over water--instead need to be planted on the eastern side of the Thar desert to produce rain clouds to rain on that region and regreen it again.

You can read my 2002 proposal at https://www.ecoseeds.com/cool.html which the Saudi government adopted in 2010 to set aside 200 million hectares as Ecological Restoration Preserves, and they are started to replant at the rate of one million trees per week, until 10 billion are planted.

You should get involved in discovering what species of "rain trees" you have in India, maybe the most important scientific discovery this century?
