llll Intro [ 배경 ] The annual average temperature of Earth has been periodically changed up and down within the range of 1.5oC with the cycle of 4~500 years. During the period of the 15’th to 19’th century the temperature has been relatively lower, and since the 20’th century the temperature has been gradually increased. Especially it is Africa, directly damaged by Global Warming. The desertification has mainly been appearedon Sahel region, south of Sahara desert in Africa, Chile in South America, North America, Asia and Australia, and so far 19% of total land area, 30 million km² is now regarded as desert region, and is the risk to mankind survival. Especially the Sahel region in Africa has been directly influenced by this desertification. Sahel region is located in thw southern region of Sahara desert withdistance of 190 ~ 290 km by north to south, east from Sudan, Ethiopia, west to Senegal, Mali, Mauritania, Niger. The recent drought, the largest one during last 60 years, has made an intense shortage of rainfall in Sahel region and East African region, Ethiopia, Somalia and Kenya, created over 10 million refugees so far, and over 2 million children are suffering from malnutrition. Though there are so many people living in Africa, the specific characters are insufficient natural resources in many areas and no technology to overcome this weak point. So the deforestation, impractical expansion of farmland and nomad have been done, but practically these are the main reasons of accelerating desertification and difficulties of their life. These Africans, lost their base of life by drought and famine, have become environmental refugee, to secure daily food for living, and under international aid program.
