Coping strategies

The United Nations University (UNU) estimates that in 2010 there

will be up to 50 million environmental refugees. Therefore, former

UN Under-Secretary-General and UNU Rector Hans van Ginkel

has called for the recognition of environmental refugees within

international frameworks, while realizing that limited resources

already restrain the relevant global organizations’ capabilities

to deal with conventional refugees.

23

This is also reflected in a

proposal by the German Advisory Council on Global Change for

managing migration through cooperation and further developing

international law.

24

In relation to dryland development there are two partially

competing, scientific approaches – the ‘desertification para-

digm’ and the ‘counter-paradigm’.

25

The older, indeed fatal,

desertification paradigm states that drylands are basically stable

ecosystems which collapse when human influence exceeds

certain levels, and, most important, that few, if any, measures

exist to prevent this downward spiral. In the more recent and

scientifically supported counter-paradigm, this is only one of

two possible outcomes. It first states that deserts are by them-

selves unstable and therefore highly vulnerable areas. This does

not neglect human influence in land degradation – and its

sometimes disastrous outcomes – but puts it into the broader

picture of natural droughts and anomalies, which are still far

from being fully understood.

Following this counter-paradigm, it is also possible,

but dependent on social developments and political

decisions, to mitigate climate induced land degrada-

tion by using sustainable farming practices or integrated

water system management. Indeed, research has been

undertaken since 2001 in a series of international work-

shops on: the role of freshwater resources and other

possible rehabilitation of drylands; sustainable manage-

ment of marginal drylands; and on prevention of land

degradation through traditional knowledge and modern

technology.

26

Climate change and desertification, with all the

underlying factors and manifold consequences, will

not be defeated easily. There are, though, ways to

respond, mitigate and adapt effectively. In addition,

we no longer lack the ability to end poverty, one of

the main human drivers as well as impacts of deser-

tification.

27

But we seem to lack the political will

to combat it effectively. It is certain that we do still

lack scientific understanding of soils, their degrada-

tion and the human dimensions of desertification.

Therefore, we should prepare for growing numbers of

environmental refugees, both nationally and globally,

to prevent further political destabilization in devel-

oping countries.
