Objectives
• View migration as a long-term process part of our past, present and future
• Imagine the future of international migration not as projected numbers but as evolving patterns out of changing social and economic contexts
• Present scenario methodology, its advantages and drawbacks
• Provide an insight view of scenario work

Migration Research: State of the Art
• What do we know about migration today?
o Multiple drivers of migration
• Economic and political drivers
• Demography - aging and youth bulge
• Education, technology, environment
• Theories and models
- “Causal factors” can have a couter-intuitive, often non-linear effect on migration
- Complex interactions between different drivers (e.g., indirect role of demographic & environmental factors)
- Long-term trends (and migration policies)

International migration in public debate
• Migration as a problem/emergency which needs an immediate solution
o Problematic approach:
• Migration is presented as a sudden short-term event rather than part of broader processes
• Migration can be controlled with the appropriate migration or non-migration policy, ignoring complexity of migration drivers
• Result: Migration policies designed to control migration with potentially unintended and perverse effects

International migration in the future
• Studying the future of international migration:
o Probabilistic projections of current trends into the future (e.g., forecasting)
o Forecasts are powerful ways to describe the future
• Quantification of the future
• Offer a range of likely outcomes
• Users of forecasts have concrete data to plan
But, how successful are forecasts?

Using forecasting models: an example
• Dustmann et al. (2003), a report commissioned by the Home Office to forecast net immigration from the AC10 to the UK after the enlargement of the EU:
o Estimations were based on rather high population growth rates in the AC10
o Net immigration to the UK from the AC10 will be ‘relatively small at between 5,000 and 13,000 immigrants per year up to 2010.’ • Two baseline projections: baseline model 1 = 4,872; baseline model 2 = 12,568
o The UK opened its labour markets to the AC10 countries on May 1, 2004

Why can a sound model deliver poor estimates?
8
• Five main reasons:
o Model applied across countries
o Model applied across time
o Explanatory variables must themselves be forecasted
o Complex levels of impacts and feedback
o Even when data are not a problem, there are uncertainties, which models are unable to incorporate
![Page 9: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/9.jpg)
Two major uncertainties:
Migration = f (yhost, yhome, networks, policy, natural disasters…)
Model uncertainties, which are
comprised of the insufficient
understanding of the mechanisms that
operate in the migration process.
Contextual uncertainties, which are found in the
constantly changing environment in which
migration occurs.
Even with certain data, when we look at the future we have uncertainties
Uncertainties
![Page 10: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/10.jpg)
Forecasting’s shortcomings
• Assumptions that:
o There is no change in context
• World the same in 2030 as it is today
o Migration will be shaped by the same drivers tomorrow as today
• Ex. Importance of technology as migration driver in 1950 and today
o Migration drivers we recognize today will continue to operate unchanged in the future
• Ex. Technology today affect transport, communication, information, production systems…tomorrow?
Assumptions that tomorrow will be the same as today 10
![Page 11: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/11.jpg)
Thinking of the future
• Why do we assume no change in the future?
o Anchoring in the present and recent past
o Undervaluation of what is difficult to imagine and difficulty in recalling less recent history (availability bias)
o Belief that we understand the context, the trends and the mechanisms that rule migration (overconfidence bias)
• Biases lead to:
o Overall lack of long-term vision and imagination on how the future of migration might look like
• Outcome: research and policy are ill-prepared

Scenario methodology
• Deconstructing our knowledge of migration
o What do we know from the past?
o What do we know about migration today that can help us understand future developments (relative certainties)?
o What is it that we don’t know (collective ignorance – uncertainties)?
o What is it that we don’t know we don’t know (assumptions)?
• Reconstructing a more subtle view of the world, notice ‘weak signs’ and possible changes in migration patterns

The Balance between Predictability and Uncertainty

![Page 14: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/14.jpg)
Scenarios: What are they?
• Scenarios are a way to
o Systematically approach possible (not just probable) developments in the
future
o Understand how the context in which migration occurs might shift
o Uncover the assumptions, promote ‘out-of-the-box’ thinking, identify certainties and uncertainties
o Prepare us for the possibility of something happening
Scenario methodology accepts that uncertainties exist and they are key factors that may shape the future

A short scenario story
15
In 2035, a combination of high economic growth and high levels of
political conflict and instability characterise North Africa.
The discovery of significant oil resources in Morocco and other Maghreb countries in the 2010s and 2020s boosted economic growth and public investment. Despite such growth, social and economic inequalities are deepening within North African societies. There is increasing competition among ethnic and class groups about the control of natural resources, which has stalled processes of democratization and led to the emergence of a new, autocratic ruling class, whose power is necessarily contested through regular popular uprisings. State politics in North Africa have been characterised by power struggles, in which political actors seek political office to gain control over state-run natural resources.
What would this mean for migration in North Africa? Sub-Saharan Africa? Europe?
![Page 16: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/16.jpg)
Scenarios’ characteristics
• Stories created using multiple perspectives on: o What has happened in the past
o What we know today
o What could possibly develop in the future
• The stories must be: o Plausible
o Coherent
o Challenging our expectations
• Scenarios neither represent a perfect world, nor an apocalyptic world – they are a mix of positive and negative events and outcomes that do not simply reproduce the status quo
16

Scenarios are visualisations of possible futures that we do not necessarily expect to come true
![Page 18: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/18.jpg)
Benefits of scenarios
• Scenarios offer techniques to develop a better understanding of migration processes
o Intuitive method that encourages the ‘break down of mental barriers’ and promotes a stimulating and creative process
o Identification of the ‘germs of change’ or ‘weak signals’
• Key role of multiple stakeholders
o Awareness that knowledge of migration is available in many segments of society
o Multiple stakeholders bring various experiences and perspectives from different sectors (i.e. business, government, academia and civil society), disciplines and backgrounds
The process is as important as the outcome

Deconstructing migration knowledge
1. What do we know from the past?
2. What is it that we don’t know we don’t know (assumptions)?
3. What do we know about migration today that can help us understand future developments (relative certainties)?
4. What is it that we don’t know (collective ignorance – uncertainties)?

What we know: Learning from the past
• Identification of continuities and discontinuities
• Migration shifts in modern history of European migration
o Post WWII economic growth and the guestworker programmes (Southern to Northern Europe and North Africa to Northern Europe)
o The 1973 oil crisis, Libya and the Gulf
o 1980s, Southern Europe increasingly attractive
o Collapse of Soviet bloc and East-West migration
o Restrictive immigration policies, transit and settlement in North Africa
• What changed in last 60 years?
• Gradual shifts or shocks to the structure?
• What changes can we expect in the next 60 years?

What we don’t know we don’t know: assumptions
The Need to Question Assumptions
• Ex.1: Development reduces migration
o If South-North migration is mainly driven by poverty and underdevelopment, development in origin countries will reduce migration (policy solution)
• “Marshall plan for Africa”
o Evidence shows that social and economic development tends to increase people’s capabilities and aspiration to migrate

The Need to Question Assumptions
The Need to Question Assumptions
• Ex.2: Where will future migrants come from? o If high fertility, population growth and poverty continue in
developing countries, we have a quasi unlimited global supply of lower skilled workers.
• To achieve a reduction of flows, migration must be controlled at the destination (policy solution)
o Evidence shows that lower fertility and higher education levels will affect future migration, but we don’t know how because effects are mediated by other factors

o Climate Change and migration
o Border control, immigration and settlement
o Economic downturns and return migration
o Transnationalism and integration

What we know: relative certainties / megatrends
• Identification of ‘megatrends’
o Megatrends are long-term driving forces or development trends that influence almost everything at all levels of society*
• Megatrends are the building blocks of all scenarios.
• Which contextual factors are relatively certain when thinking about migration between now and 2035 in Europe?
o Demographic changes and aging?
o Rising education levels?
o Improvement of technology?
o Ethnic and social transformation (diversity)?
• What impact may these factors have on future migration? (in their interaction with other contextual factors)

Assessing what it is that WE KNOW
• Demographic transitions: fertility rates, mortality rates, population structure, youth cohort, dependency ratios
• Increasing literacy and education
• Economic diversification, urbanization and labour structure
• Advances in communication and transportation technology (facilitating access)
Effects on migration are uncertain because they are
mediated by crucial economic and political uncertainties.

Sources of Uncertainty
• What drives migration ? (the models, theories)
- What will be the causal factors in the future?
- Will the mechanisms driving migration change in the future?
• But also, how will drivers of migration evolve in the future? (the context)
- What are the uncertain factors?
- Could they be the source of shocks to the system (e.g., Oil Crisis; 9/11; Global Financial Crisis, radical political change)?

Exploring what we don’t know
• Breaking down the uncertainties
o What is known about them (secondary research)? • Ex. Agricultural innovation and water access in North Africa
– New technologies to reduce water consumption introduced
– Subsistence agriculture diminishing in importance
– Agricultural industry for distribution of Europe growing – stress on water for local population
o How are they expected to change (experts in these fields)?
• What are possible outcomes?
• In what circumstances are these outcomes expected?
o Using logic and intuition to assess:
• What are the possible interactions with other factors and the possible outcomes?

A short scenario story
51
In 2035, a combination of high economic growth and high levels of
political conflict and instability characterise North Africa. The discovery of significant oil resources in Morocco and other Maghreb countries in the 2010s and 2020s have boosted economic growth and public investment. Despite such growth, social and economic inequalities are deepening within North African societies. There is increasing competition among ethnic and class groups about the control of natural resources, which has stalled processes of democratization and led to the emergence of a new, autocratic ruling class, whose power is necessarily contested through regular popular uprisings. State politics in North Africa have been characterised by power struggles, in which political actors seek political office to gain control over state-run natural resources.
What would this mean for migration in North Africa? Sub-Saharan Africa? Europe?
![Page 52: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/52.jpg)

Reporting your scenarios
• Please select one or two persons who will report the scenario back to the plenary
• Feel free to find creative ways to present your story, for instance: o You could be a reporter describing an event occurring in 2035 with
background information
• (e.g., the violent episodes that occurred today, July 14, 2035 shock us, but they should not surprise us. The situation has been in the making for the past 20 years….)
o You could act as two friends discussing some developments/events who provide their reflections
o You could be a policy advisor providing evidence for advice on migration policy today in light of what is bound to occur in the next 24 years

Important questions for the future of migration
• Technology will bring change, but it’s unclear how it will affect our lives
o What is the future of alternative energy?
o Will innovative technology allow important changes in production technology?
o How will these affect future labour force needs?
o How will future ICT affect our lives? Could migration be further facilitated or possibly avoided?
o Will increased technology used at the borders prevent or facilitate migration?

![Page 56: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/56.jpg)
Important questions for the future of migration
• Population ageing and declining population growth are certain, but: o What will this mean for native workers in Europe? What role for the
trade unions? How will these changes affect international migration?
• Environmental change is anticipated, but: o To what extent? How rapid and severe? To what extent will
populations at risk be able to adapt? Will movements be internal and temporary?
• Cultural changes will continue as always, but: o What of xenophobia? How important will religion be in the future?
Will xenophobic attitudes act as greater repellents of migrants? Will a ‘culture of migration’ become the norm in the society of the future?

Conclusions on the scenario methodology
o Scenario work helps us think in the long-term with a free and clear mind as we are not in an ‘emergency mode’
o Looking closely at uncertainty and thinking creatively about how stakeholders may react helps us expand our ‘set of options’ for future behaviour

![Page 58: Exploring Future International Migration: A Scenario Approach€¦ · International migration in the future •Studying the future of international migration: o Probabilistic projections](https://reader034.fdocuments.net/reader034/viewer/2022042105/5e83977589ad5844d31cb3a8/html5/thumbnails/58.jpg)
Conclusions on the future of migration
o Migration is a complex and multi-dimensional phenomenon, part of social processes and social change
• Important uncertainties include not just the economy, labour markets and policies, but also political systems, technology, environment, international relations, cultural factors
o Migration policy is only one of the many factors that affect migration – both today and in the future • Attention must be paid to non-migration policies (e.g. labour
market structures, welfare provisions in origin and destination countries, etc.)
