The world local economy was affected by the environmental deterioration. For instance, overfishing, loss of timber as a result of deforestation..etc these degradations of the environment has become more clear. In other words, actions such as deforestation has to have consequences such as rainfall runoff, erosion, flooding and so on.
==> agriculture.
Agriculture, according to archeologists, is the link between environmental deterioration and economic decline which started with water logging and erosion converting fertile wheat lands to desert.
The first sign that the world is on an economic and demographic path that is not environmentally sustainable was the rise of grain prices, followed by a doubling of grain prices in early 1996.
consequently, heads of households were unable to buy enough food to sustain their families and as a result the governments were taken responsible for such thing. Such situation multiplied, and since the worlds was expanding as well, it is becoming difficult to meed everyone's need
In research of land.
As the world population continues to expand, cropland and the amount of irrigation water are shrinking too. Many methods to expand the eras to produce crops include irrigation, terracing, drainage were used by farmers overtime. However, the frontiers of agricultural settlement has mostly disappeared after reaching its peaks in different time ranges.
In research of water
water scarcity, is another serious problem facing the world. High demands for water even resulted in a per-dried river before it reaches the sea. Most of world's wheat is produced on irrigated land since irrigation expanded faster than population. At the end of this, a sort of a competition has taken place between regions, making the losers import grains. That is, there is a shrinkage in both grain land and irrigation water.
The onset of food scarcity
food scarcity has been accumulating by the degradation of the earth. Such thing has seen the light from overfishing, grain land productivity decrease below the growth in demand. In the United State grain stocks cannot be rebuilt with an outstanding harvest. Prices of some grains set higher records, not to mention the elimination of bread subsidy in Jordan because of the imported wheat high prices and the increasing fiscal deficit.
An unprecedented challenge.
It turned out that a revolution in human reproductive behaviour and stabilizing population and climate are the hard to get components to secure food supplied. The first component would challenge a generation. Climate stabilization means taking alcohol actions. Reducing carbon emissions means reducing fossil fuel burning and also increasing the efficiency of energy use. Water and land have also to be protected in order to meet future needs
when we secure food supplies, we will secure the whole upcoming future for next generations
