Starting Statements
• Climate has never been stable but we did not really notice.
• Land degradation started with agriculture, irrigation several thousand years ago.
• Urbanisation was seen as a sign of development.
• Migration is a steady component of human history.
…but things are spiraling out of control

Millenium Ecosystem Assessment 2005
• 15 of 24 ecosystem services are degraded or utilised in an unsustainable way, mainly by humans for the supply of specific services.
• This could accelerate the degradation of ecosystems - scientific evidence still required.
• The poor and especially rural poor are suffering most by the decline in ecosystem services.
• 2 billion people living in dry regions are extremely vulnerable to the loss of ecosystem services.

Millennium Ecosystem Assessment 2005 Some Conclusions on Drylands
• 10 to 20 percent of drylands are already degraded.
• Pressure is increasing on dryland ecosystems for providing services such as food, and water for humans & livestock, irrigation, and sanitation.
• Climate change is likely to increase water scarcity in regions that are already under water stress.
• Droughts are becoming more frequent and their continuous reoccurrence can overcome the coping mechanisms of communities.

The Unstoppable Trend of Urbanisation
• The accelerating spiral

Year Population Rate of Increase
1800 200,000 3.5%
1900 700,000~9.0%
2000 6,200,000 ?
In 2000 16 cities had more than 10 million inhabitants: 4% of the world population
• How many people must remain in the rural environment?
• Good Estimate: % of people needed to produce our food (could go down to 5%??)

Migrations due to Mixture of “Push” and “Pull” Factors
• Some root causes include (Boswell and Crisp, 2004;
Hatton and Williamson, 2003; Schwartz and Notoni, 1994):– Economic factors (poverty, unemployment, wage
disparities)– Social factors (poor welfare or education;
demography)– Environmental factors (degradation of
ecosystems)– Degraded security conditions (disrespect for
human rights)– Existence of migrant networks

• Droughts and loss of land productivity can become important factors triggering the movement of people from drylands to other areas (MA, 2005), particularly once coping mechanisms and adaptation strategies are impaired by the loss of ecosystem services.
• Sea level rise and environmental calamities may trigger migration.
• Disasters of “natural” origin may prompt people to leave.

Debate over the Concept of Environmental Migrants / Refugees
• Critics (not exhaustive list):– Multiple “push” & “pull” factors so why highlight the
environmental component?– Poor definition of what is an Environmental
Migrant/Refugee– Risk of watering-down 1951 Convention relating to
the Status of Refugees– Use the argument put forward by others that
desertification, land degradation, climate change and sea level rise are not as serious problems as characterised by certain “lobbies”

Adopting a Precautionary Principle
• “…estimates and projections of environmental refugees are based almost entirely on anecdotal evidence (…) [but] it is important not to trivialize the role environmental change and resource depletion may play in population movement.” (Lonergan and Swain 1999:2)
• Actions above all are needed to tackle the issue:– Actions related to the reduction of desertification rates and
climate change (considering all the dimensions) and when possible implement restoration and adaptation strategies
– Policies and actions that deal with the immediate and/or forthcoming issue of environmental migration / refugees
– The two need to be further developed in parallel

Suggestion: Establish an Intergovernmental Panel on Land Degradation
• Concept along the lines of the IPCC:– Assess scientific, technical and socio-economic
information to understand:• risks linked to human-induced land degradation• potential impacts• options for adaptation and mitigation
– Scientific approach, not advocacy
– Regular assessments of state of knowledge on our lands and their soils including the social implications

Proposed Categories of Environmental Migrants
Environmentally motivated migrants “pre-empting the worst”
– Individuals “may” leave a deteriorating environment which could still be rehabilitated
– Both temporary and permanent displacement / migration
– Examples: depopulation of old industrial and mining areas, most rural exoduses
– Case: rural exodus from Northeast Brazil to Sao Paolo due to long dry spells

Five Pronged Approach
• Science: – Establish and implement programs to allow a better
understanding between the cause-effects mechanisms between degradation of ecosystems and social systems
– Develop proper definitions of environmental migrations, environmental migrant/refugee.
– Provide long-term, sustained funding for research.
• Awareness: – Raise knowledge-based public and political awareness
and its social, economic, environmental dimensions

recognition of environmental migrants such as in a specific Convention or in parts of Intergovernmental Environmental Treaties
• Humanitarian aid: – Empower the United Nations system and other
major assistance organisations to provide aid to environmental migrants / refugees
