Explanations:Terrace farming is an agricultural technique used in mountainous or hilly regions to cultivate crops on sloped land. The method involves creating a series of terraces or steps on the slope, which helps to prevent soil erosion and manage water flow effectively. Each terrace is typically level, allowing for the cultivation of crops such as rice, which requires a significant amount of water.
In the context of Indian states, Nagaland is a northeastern state characterized by its hilly terrain. The state's topography is conducive to terrace farming, particularly for rice cultivation. The practice of terrace farming in Nagaland is deeply rooted in the local agricultural traditions and is essential for the region's food security. The terraces not only help in managing the steep slopes but also ensure that the water is distributed evenly across the fields, which is crucial for rice cultivation.
Other states like Gujarat and Kashmir have their own unique agricultural practices. Gujarat, for example, is known for its dry farming techniques and the cultivation of crops like cotton and groundnuts, which do not require the use of terraces. Kashmir, on the other hand, is known for its valley agriculture, where the flat land in the Kashmir Valley is used for various crops, including rice, but not specifically through terrace farming.
Therefore, the correct answer to the question of where terrace framing of rice is done is Nagaland, as it is a region where the hilly terrain necessitates the use of terraces for effective rice cultivation.
