Step 1: Understanding the Concept:
In India, one of the early methods for defining the poverty line was based on the minimum calorie intake required for subsistence. The Planning Commission adopted this methodology based on the recommendations of the Y. K. Alagh Committee in 1979.
Step 2: Detailed Explanation:
The committee differentiated the calorie requirement for rural and urban populations based on the nature of work.
Rural Areas: People in rural areas are often engaged in more physically intensive labor (like farming). Therefore, a higher calorie intake was recommended. The figure was set at 2,400 calories per person per day.
Urban Areas: People in urban areas generally have more sedentary lifestyles with less physical labor. Hence, a lower calorie intake was recommended. The figure was set at 2,100 calories per person per day.
Step 3: Final Answer:
The recommended nutritional requirements are 2,400 calories for rural areas and 2,100 calories for urban areas.
