Why is land scarce?
Land is another resource that is becoming increasingly scarce and putting a strain on the agricultural industry. As the population grows, there are a number of reasons why land availability is negatively impacted, foremostly a result of the fight for industrialization, urbanization, and housing versus agricultural growth. While some argue that increased urbanization poses a threat to agricultural growth, some studies indicate that the threat is a bit more complex.#N#At a glance, urbanization is usually considered a threat to agricultural growth: as urban expansion increases at the expense of agricultural land, we generally see a loss of physical resources when it comes to agricultural growth.
