Assess the success of different methods used to overcome the imbalance between population and food supply

Extracts from this document...

Introduction

Assess the success of different methods used to overcome the imbalance between population and food supply The term imbalance refers to a difference between the population's demands for food and the actual food supply. It is estimated that the current population of the earth is six billion people. There are two main theories that relate to population growth and food supply, these being the "Malthusian theory" and the "Boserup theory". Thomas Malthus was an English clergyman and economist who lived from 1766 to 1834; Malthus expressed a pessimistic view over the dangers of overpopulation. He believed that the food supply was the main limiting factor to population growth. He also believed that human population increases geometrically whereas food supplies can only grow arithmetically. ...read more.

Even though in theory it achieved what it was set up to do it still had many disadvantages. Many farmers who invested heavily in the new technologies brought in from the western world found themselves laden with massive debts. An example of this is the Punjab area of India where the debt in rural areas has run to a staggering fifty billion rupees (�745 Million). Also excessive pumping has led to a drop in groundwater and the water has become saline. Other problems cased by the green revolution include: > Human population growth > Diminished "biodiversity" in crops > Inherent soil fertility and water quality > Pesticides > Land degradation Demographic Response A demographic response to over population is China's one child policy. ...read more.

Conclusion

This however has had some very serious implications these include: > Human rights issues > Female infanticide > Sex imbalance > Aging population The policy is also difficult to enforce in rural areas where the policy is more open to corruption as large families are needed to support their parents in old age. Sometimes pregnant women would even be sent to relatives so that a child would be unregistered. This policy has proven to be fairly successful as it has managed to reduce population growth so that the population is remaining stable however it has not managed to reduced the population and it is not meeting its targets. My conclusion is that both approaches to tackling this global problem have positives and negatives to be taken from them. But on the whole they are causing more problems than they are solving so therefore I believe that both solutions are failing. ...read more.

    In other words the more people they are the more pressure placed upon their current technology which would mean that there is more demand for new technology.
