The pioneering work of Malthus (1798) has suggested population growth as the most detrimental factor for food security. In the classical Malthusian theory, food shortages exist due to the presence of too many people as compared to the amount of food supply, and thus, exacerbated food insecurity in the long-run (Malthus, 1798). Empirically, Ehrlich et al. (1993), Postel (1998), Gilland (2002), Faisal and Parveen (2004), Alexandratos (2005), Schneider et al. (2011), Molyneux et al. (2012), Tian et al. (2016) and Hall et al. (2017) showsshow that a substantial increase in a number of populations is found to lead to greater resources usage, which in turn affects the capacity of agricultural productivity. While Lutz et al. (2002), Carvalho (2006), Charles et al. (2010), Applanaidu et al. (2014), Szabo (2016) and Hall et al. (2017) showsshow that a growing number of populations, accompanied with growing demand for more food, are contributing to thean insufficient amount of food to feed its entire population.
