Although population growth is the basis for development and investment; it also contributes to the increasing pressure on scarce resources and necessary constructions that impact on the environment.
The world population is expected to rise by around 2 billion by 2050.
OECD in its 2003 review highlights that all growth will virtually be in the developing populations of Asia and Africa. This explains the growth will put increased pressure on resources and structures that are already inadequate and unacceptable.
In term of impact and ecological effects, Ferrinni in 2012 considers the size of population contributes to describing the enormousness of a country’s environmental impact. By monitoring and adjusting the rate of population growth is some discretionary control policy for reducing environmental deprivation, particularly in developing countries where degradation control could be banned. The population, on the other hand, is respectively the source for growth, in manufacturing and to producing goods and services.
Even with a population growth of more than 50% and the progress of nutrition production; nearly one billion people get up hungry, most of them women and children.
Although achievements have been made in reducing the global population of those undernourished from about 26% in 1971 to 13% in 2008; the global economic crisis has turned more people into poverty and hungry. In 2011, Sheeran describes the World Food Program has been undertaking the most thoughtful transformations, as it moves from a food-aid intervention to one that helps individuals, communities and countries to building sustainable food security. Meanwhile this response is keener, more directed, and is able to help the most vulnerable individuals prepare to endure shocks such as natural disaster, economic crisis’s or food price variability.
