The correct answer is: a) Agri-silviculture.
Agri-silviculture is a traditional farming system in Nagaland that integrates crops, livestock, and trees. It is a sustainable form of agriculture that helps to protect the environment and improve the livelihoods of farmers.
Agri-silviculture involves planting trees on agricultural land. The trees provide shade for the crops, which helps to reduce the need for irrigation. The trees also help to improve the soil quality and prevent soil erosion. In addition, the trees can be used for firewood, timber, and other products.
Agri-silviculture is a beneficial practice for both the environment and the farmers. It helps to protect the environment by reducing deforestation and soil erosion. It also helps to improve the livelihoods of farmers by providing them with a source of income from the sale of crops, livestock, and trees.
