UNITED NATIONS, Aug 11 (IPS) - With political will to dramatically cut the world's greenhouse
gas emissions failing to materialise, a multi-pronged approach
is needed to protect the millions of people who are being
displaced as a result of environmental factors driven largely
by climate change, experts say.
"Climate change is looming as a potentially very serious and
underappreciated complicating factor when it comes to international
displacement," said Erika Feller, the assistant high commissioner for
protection in the office of the U.N. High Commissioner for Refugees.
More is needed from the international community to address this
challenge "in a coordinated and pragmatic manner", she told IPS.
Of paramount importance is that national authorities play a central
role in developing appropriate responses to both the internal and
external dimensions of climate-related displacement, while affected
persons and communities must be made fully aware of their rights and
given opportunities to participate in decision-making, Feller said.
"Decisions about where, when and how to relocate communities, for
example, must be made in consultation with the affected populations
and be sensitive to cultural and ethnic identities and boundaries to
avoid possible tensions and conflicts," she added.
Staying close to home
The overwhelming majority of people who are displaced by environmental
factors become internally displaced persons (IDPs) within their own
countries. Just a fraction will likely cross international borders,
said Michele Klein-Solomon, director of the Migration Policy, Research
and Communications Department at the International Organisation for
"[The latter group tends to move] from countries in the South, in the
developing world, to other countries in the 'less emitting world', and
it is also not likely to be the most vulnerable who move," she
More frequent and severe floods, storms, landslides or land
degradation, droughts and water shortages - so called slow-onset
natural and human-made disasters - can all be triggers for migration.
Those most in need of protection tend to lack sufficient resources to
adapt to the new living conditions, and that can include an inability
to move away or migrate to other countries.
Speaking at a conference at Columbia Law School in May on migration
and climate change, Klein-Solomon stressed that it was important to
grasp these facts to counter "the overwhelming fears of the developed
world being awash with people who are coming into their countries,
taking jobs and burdening social security mechanisms".
Even under worst case scenarios, in which some 250 million people
could be displaced due to climate change over the next 25 to 30 years,
it still would be "a tiny portion of the world's population", she
"We are really not talking about enormous numbers relative to global
populations and we are not talking about hordes of people flooding
into the Western, industrialised, developed countries. We do not need
further repressive legislation and xenophobic debates as a result of
this discussion," she added.
Few legal protections
Rapid-onset disasters attract far more attention from the media,
policymakers and researchers than gradual environmental changes - such
as the human consequences of rising sea levels, soil salination,
deforestation and desertification.
Precise estimates on climate-induced migration are hard to come by.
However, recent events such as last year's nationwide flooding in
Pakistan, severe mudslides following heavy rainfall in Brazil and
Colombia this spring, and the ongoing humanitarian disaster in
drought-hit Somalia show that millions of people are already being
driven from their homes and property due to extreme weather patterns.
International protection strategies are often marked by a humanitarian
focus on "the immediate need of the person without necessarily looking
at the causes of the phenomenon nor to a response in a longer term,"
said Paola Pace, acting head of the International Migration Law Unit
at IOM's International Cooperation and Partnerships Department.
When emergencies occur, immediate funding is provided which lasts
about three to six months, but for the subsequent "recuperation phase"
it is very difficult to find donor support. This wastes the knowledge
acquired in the initial months and squanders an opportunity to "really
tackle the causes that brought about that emergency", Pace stressed in
an interview with IPS.
The lack of a long-term strategy is a major problem for those seeking
to protect and support affected populations. A better approach would
go beyond basic needs - food, water, shelter - to address trauma and
stress-induced illnesses, and provide opportunities for sustainable
development in a new environment, she said.
The climate-displaced also face an uncertain legal situation. Neither
international humanitarian law nor international refugee law has a
legal definition for this group, making it difficult to hold
governments responsible for their wellbeing.
Often, there are multiple, complex, interconnected factors at work,
from extreme weather events to land degradation or sea-level rise, and
identifying the exact culprit is impossible.
"[I]t is a bit like the straw that broke the camel's back," said Jane
McAdams, an expert on refugees and international migration law at the
University of New South Wales.
"Climate change is never the only reason why people move, there are
always other factors like underlying socioeconomic conditions, for
example," she told IPS.
Finding appropriate legal and policy responses requires a combination
of strategies, "rather than an either/or approach", she said.
While there is no single legal standard specifically addressing
environmental migrants, the IOM's Pace stressed that should not give a
"wrong impression" that no framework applies.
"Before a person becomes a migrant she or he is a human being," and
entitled to every protection under human rights law, she said.
