Detailed explanation-1: -Population growth is rapidly accelerating, intensifying the pressure on food production. This, in turn, leads to higher food insecurity, more greenhouse gas emissions, and large-scale environmental degradation. Food production, therefore, needs to adapt to accommodate a growing population and a changing climate.
Detailed explanation-2: -World population has risen at a rate of 1.9% per year since 1960, but food production has grown at 2.8% per year due to the application of better crop production techniques.
Detailed explanation-3: -An ageing population structure within a country will cause a decrease in labour force for food production, therefore, cause a reduction in the supply of food. This has made the future development of food production further rely on technological innovation, but not a labour expansion.
