Meanwhile, other academics have also been turning their attention to the potential crises that climate change might trigger. Last month, the UN issued a stark warning that climate change and associated desertification will undoubtedly trigger conflicts and mass migrations in the near future.
The analysis, by the
Based on the input of 200 experts from 25 countries, the analysis urges governments to adopt a broader, overarching view and a more coordinated, integrated and interlinked approach to dealing with desertification, climate change, poverty reduction and other public concerns. "Some forces of globalization, while striving to reduce economic inequality and eliminate poverty, are contributing to worsening desertification. Perverse agricultural subsidies are one such example," says Prof. Hans van Ginkel, UN Under Secretary-General.
Astonishingly, the report says that one-third of all people on Earth are potential victims of desertification's creeping effect. And, left unchecked, the number of people at risk of displacement due to severe desertification is an estimated 50 million over the next 10 years.
"Addressing desertification is a critical and essential part of adaptation to climate change and mitigation of global biodiversity losses," says Prof. van Ginkel. "The expected climatic change scenarios as projected by the recently published report of the IPCC give an additional dark shade to an already gloomy picture. However, it is difficult to properly quantify the number of environmental migrants and the migration routes as long as the concept itself remains debated even from a scientific point of view," he concludes.
