Explanation:

Ester Boserup had a different view of population growth than Malthus.  Malthus believed that the potential for population growth is exponential, whereas the capacity for the land to support the growing population in agricultural terms was only linear.  Boserup's theory holds that increases and decreases in population will change the intensity of agricultural practices in society and so human ingenuity is an important part of the dynamic.
