Scarcity is an economic term that is intentionally created by the economic system for profit and expresses that the production level reached by the operation of the resources of production with the current level of technological development is insufficient to meet the endless human needs and desires.
Climate factors leading to weather events and climate in the world (the angle of arrival and latitude change of sun rays, distribution of land and water masses, ocean currents, prevailing winds, places of low and high pressures, orographer and height) have caused the emergence of many climate types and climatic zones and belts. Therefore, according to these factors on Earth, many areas have been formed as semi-humid, humid, semi-dry, dry and desert regions. Conservation of the natural balance of these areas is directly related to climate conditions representing these regions. Fluctuations in climate can lead to unexpected dangerous events that could turn into natural disasters.
In humid, semi-humid and semi-dry regions, the lack of rainfall in a certain period of time causes drought, Drought and desertification in regions and desert regions can cause even more severe living conditions and the desert expands.
The causes of famine are usually addressed in two main categories: natural and human. Natural or physical causes, such as drought, extreme rain and floods, seasonal cold, typhoons, plant diseases, and harmful insects that have been exposed to products, can lead to the destruction of products and food resources. Drought is the most common natural cause of famine, leading to hunger in barren or semi-barren places. Drought, which is the source of an important river used in irrigation, can lead to famine in regions where the river irrigates.
The first famine recorded in history was the 4th century BC. it has been seen in Egypt and the Middle East for millennia. This first scarcity is also called physical scarcity, as the natural environment is caused by the intensive lack of built-up agriculture. Asia is the main region of the world that has suffered famine since the 1700s. The shortage of food caused by the population has been a determining factor in most of the famines in this continent. These also occurred at the transitional level, or slightly above the level of agricultural crop obtained from drought, but from time to time in the regions suffered floods.
India and China are among the countries where extreme population-related famine is most common. In India, the famine between 1702-04 and 1702-04 has resulted in more than 2 million deaths. Between 1876-79, 9-13 million people are thought to have died in the famine affecting the north of China. In Ireland, the famine caused by the plant disease that destroyed the potato crop in 1846-47 resulted in the death of 2-3 million people. Between 1971-73, the drought led to the deaths of 1.5 million people in Ethiopia. The famine that began in the mid-1980s threatens the health of 150 million people living in the arid region south of the Great Sahara in Africa.
