The international immigration is not a single issue, but a multifactorial one, with spectators as well as unseen sides. In economic and political flight we have to take into account the environmental flight as a parameter, such as famine and drought, when because of the climate instability, 100 million people have been displaced in the 21st century alone.^ο century. Although there is no single and exclusive cause of external or internal migration, we must remain sensitive, both because underdevelopment and overpopulation affect us all and because the situation may soon become unmanageable - as is evident at least after the recent epic intergovernmental report on climate change (Climate Change 2021: The Physical Science Basis).

Of the 40 million Afghans, about one-third will face immediate food shortages, as the agency's Global Support Programme now points out World Food Programmes (WFP) of the United Nations for the coming winter when the 2 million children living in mountainous areas are undernourished. The United Nations (UN) in the respective Summary Report on Afghanistan (UN) states that 14 million Afghans are now facing hunger due to warfare, climate change, rapid urbanisation, underemployment and pandemic in Central Asia.

The UN supported 1.7 million people across Afghanistan in June 2021 with food and at a cost of $4.7 million. Also, 375,000 children and pregnant women received formal care and food assistance to prevent future malnutrition. In the second half of the year, from July to December 2021, $234 million is needed immediately to meet the nutritional needs of people in the desert. This year the drought affects 23 out of 34 provinces in total, with the result that the needs more than double.

The difficulty in feeding on a daily basis is due to the always difficult dry climate, which is why Afghanistan has been receiving humanitarian food aid since 1963. Η the great drought of 1971 - 1972 and the dissipation of international food aid, made left-wing Afghans seek a fair deal for survival. Because of the lack of goods from state corruption, the king Zahir Zhah is overthrown by the Democratic People's Party on 17 July 1973. But the feudal structures of Afghanistan would not change much in the next few years and that is why one side (the Khalq) of the Democratic People's Party went ahead with the communist revolution on 27 April 1978.

The Islamic revolution of the Mujahideen since 1979 has opened the refugee pipeline from Afghanistan less towards the West, but mainly towards neighbouring and homogeneous states. Within a decade, from 1979 to 1989, in total fled as refugees to the two neighbouring states of Iran and Pakistan, more than 5 million Afghan refugees. Indeed, many refugees never reached their final destination because many died on the road of refugee from the cold and hardships, leaving behind their orphaned children as refugee children in the refugee camps in Iran and especially the Islamic fanatics in the medreses of the new refugee areas in the Pakistan.
