- Why the variation in estimates? Different estimation methods used Variations in environmental degradation scenarios Lack of precise definitions about who the migrants are
- Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas. It is caused primarily by human activities and climatic variations .“ Desertification does not refer to the expansion of existing deserts . It occurs because dryland ecosystems [...] are extremely vulnerable to over-exploitation and inappropriate land use. Dryland ecosystems cover over one third of the world‘s land area. Over 250 million people are directly affected by desertification , and about one billion people in over one hundred countries are at risk . Combating desertification is essential to ensuring the long-term productivity of inhabited drylands. Unfortunately, past efforts have too often failed , and around the world the problem of land degradation continues to worsen.
- Aral Sea, Uzbekistan, Kazakhstan The name “ Aral Sea “ comes from the word “aral” meaning island. The sea’s name reflects the fact that it is a vast basin that lies as an island among waterless deserts. The Aral Sea was once the world’s fourth-largest inland sea. Its problems began in the 1960s and 1970s with the diversion of the main rivers that feed it to provide for cotton cultivation in arid Soviet Central Asia. The surface of the Aral Sea once measured 66 100 km2 (25 521 square miles). By 1987, about 60 per cent of the Aral Sea’s volume had been lost, its depth had declined by 14 m (45 feet), and its salt concentration had doubled, killing the commercial fi shing trade. Wind storms became toxic, carrying fi ne grains of clay and salts deposited on exposed sea floor. Life expectancies in the districts near the sea are significantly lower than in surrounding areas. The sea is now a quarter of the size it was 50 years ago and has broken into two parts, the North Aral Sea and the South Aral Sea. Re-engineering along the Syr Darya River delta in the north will retain water in the North Aral Sea, thereby drying the South Aral Sea completely, perhaps within 15 years.
- L AKE C HAD, A FRICA Lake Chad, located at the junction of Nigeria, Niger, Chad, and Cameroon was once the sixth-largest lake in the world. Persistent droughts have shrunk it to about a tenth of its former size. The lake has a large drainage basin—1.5 million km2 (0.6 million square miles)—but almost no water flows in from the dry north. Ninety per cent of lake’s water fl ows in from the Chari River. The lakebed is flat and shallow; even before the drought, the lake was no more than 5-8 m (16-26 ft) deep. Considered a deep wetland, Lake Chad was once the second largest wetland in Africa, highly productive, and supporting a diversity of wildlife. The lake is very responsive to changes in rainfall. When rains fail, the lake drops rapidly because annual infl ow is 20-85 per cent of the lake’s volume. Human diversion from the lake and from the Chari River may be significant at times of low flow, but rainfall is still the determining factor in lake level. This image set displays a continued decline in lake surface area from 22 902 km2 (8 843 square miles) in 1963 to a meager 304 km2 (117 square miles) in 2001.
- Genfer Konvention: - ausserhalb des Landes Begründete Furcht vor Verfolgung Verfolgung aufgrund von Rasse, Nationalität, Religion, Zugehörigkeit zu einer bestimmtenSozialen oder Politischen Meinung 1951 Geneva Convention on the Status of Refugees> the person must be outside their country of nationality or former habitual residence; the person must fear persecution ; The fear of persecution must be for reasons of one of the five convention grounds ( race, nationality, religion, membership of a particular social group or political opinion ); and the fear must be well-founded . Many variations of El-Hinnawi’s definition since 1985 e.g. Jacobson 1988, Myers 1993 Definitions with respect to “environmental refugees” generally have in common the fact that they do not distinguish whether the persons migrating or fleeing have crossed an international border. However, other than this commonality, definitions vary greatly, including whether displacement of environmental refugees is temporary or permanent in nature.
- Temporär oder Permanent Interne oder über Nationale Grenzen gehend Freiwillig oder unfreiwillig Aufgrund von plötzlichen oder schleichenden Naturgefahren This definition s eeks to encompass population movement or displacement: Temporary or permanent; internal or cross-border Regardless of whether voluntary or involuntary Due to sudden or gradual environmental change
