The correct answer is: a) Afforestation.
Jadav Payeng, also known as the “Forest Man of India”, was awarded the Padma Shri for his work in afforestation. He single-handedly planted a forest on a sandbar in the Brahmaputra River in Assam, India. The forest is now home to a variety of wildlife, including tigers, elephants, and deer.
Afforestation is the process of planting trees on land that was previously not forested. It is a key part of efforts to combat climate change, as trees absorb carbon dioxide from the atmosphere. Payeng’s work has been recognized by the Indian government and he has been awarded the Padma Shri, India’s fourth-highest civilian award.
The other options are incorrect because they do not accurately describe Payeng’s work. Wildlife conservation is the protection of wild animals and their habitats. Organic farming is a type of agriculture that does not use synthetic chemicals. Tribal welfare is the promotion of the well-being of tribal people.
