A Geographical Analysis of Population Pressure and Food Security in Karnataka: Using Malthusian and Boserup Theories

The relationship between population growth and food supply has long been debated in development and environmental studies. Thomas Robert Malthus (1798) argued that population increases geometrically while food production grows only arithmetically, leading to inevitable scarcity and crisis. In contrast, Ester Boserup’s (1965) challenged this pessimistic view, proposing that population pressure acts as a stimulus for agricultural innovation and technological advancement. According to Boserup, necessity drives intensification, farmers respond to growing population density by adopting improved methods and that what happened in case of Karnataka over the three decades, investing in irrigation, fertilizers, and new crop varieties. Together, these two perspectives define the classical tension between “Malthusian constraint” and “Boserupian adaptability.”
