<h3>Globalization has led to a sharp increase in trade and economic exchanges, but also to a multiplication of financial exchanges. In the 1970s world economies opened up and the development of free trade policies accelerated the globalization phenomenon. Between 1950 and 2010, world exports increased 33-fold.</h3>
As the resources in the world are distributed unequally, the crops and the ability to grow them in specific environmental conditions such as near the river valleys, on the foothills of the mountains and near the flood plains differ worldwide as many places don't have enough sunlight,
many places is too warm or hot for there growth and other place are too cold or are locates at great heights. Variation thus exists in the cropping patterns and the cropping intensity as they need specific conditions as climate, weather, and soil properties.
Many of the earlier civilizations developed and prospered near the river valleys.
