The map is kind of misleading. It shows Kerala one of the greenest States in India as as the least green while states like Rajastan where you can find hardly any greenary is marked as most green.

Edit: I know it shows the % increase in greenary. What I meant is the "greenary" shown in the map actually has almost no correlation with the greenery in the real world. Looking the map and expecting Rajastan to be a green area would be a bad idea.
