Agriculture is the backbone of economic development of Nepal. justify the statement with suitavles examples​

Answers

Answer:

In Nepal, the economy is dominated by agriculture. In the late 1980s, it was the livelihood for more than 90% of the population, although only approximately 20% of the total land area was cultivable, it accounted for, on average, about 60% of the GDP and approximately 75% of exports. Since the formulation of the Fifth Five-Year Plan (1975–80), agriculture has been the highest priority because economic growth was dependent on both increasing the productivity of existing crops and diversifying the agricultural base for use as industrial inputs.

Terraced farming on the foothills of the Himalayas is a common sight in many of the villages in Nepal

According to the World Bank, agriculture is the main source of food, income, and employment for the majority.It provides about 33% of the gross domestic product (GDP)

Additionally, economic activities such as industry, commerce, and services do not exceed the economic contributions provided by agriculture.
