Lecture 6: migration as adaptation Flashcards
What is a foresight?
Group
Who created the DTM?
Thompson (1972)
Who created the mobility transition model?
Zelinsky (1971)
What is stage 1 of the MTM?
pre-modern society: little spatial mobility, low migration and confined to inter-rural field
What is stage 2 of the MTM?
Early transitional society: undergone change which caused migration to increase driven by the individual hope for economic opportuities
What is stage 3 of the MTM?
Late transitional: society develops causing rural-urban migration to decrease and instead inter-urban migration increases
What is stage 4 of the MTM?
Advanced society: highly developed society whereby urban-rural migration increases as the society is now so connected that access to economic activities are connected everywhere
What is stage 5 of the MTM?
Future super-advanced society: inter and intra-urban migration. Not a stage but a growing speculation
What are circulation and diurnal migration?
Circulation: temporary shift in residence involving 1+nights away
Diurnal: commuting or shopping
Why is migration the most challenging aspect of population projectiosn?
because migration is very unpredictable and does not have an international standard of measurement
What are 6 reasons for moving?
Household risk diversification Macro-scale systems cultural norms lifestyle city lights effect love persecution climate change (amplifies all mentioned)
What is expected to happen to international migration as an amount and % of overall migration?
expected to increase in amount but because the population is expected to overall increase in size the % will decrease.
How many internal and international migrants were there in 2009?
Internal = 740 million International = 210 million
What is climate change expected to do for displacement?
Expected to increase displacement but this will be concentrated in the developing low income countries
Why will displacement be concentrated in the developing and low income countries?
Because they rely most upon the ecosystems and environments that will be worst affected.
What are the types of climatic stimuli?
Sudden onset (e.g. floods) that can drive sudden migration Slow onset (e.g droughts) that can cause gradual migration through massive changes to people's livelihoods. Exacerbation of effects from climate change as well as introduction of new ones
What are the identified 4 hotspots of cliamtic stimuli through climate change?
Arctic (perfafrost, sea and ice melt)
High latitudes and wet tropics (heavy precipitation and floods)
Mid to low latitudes and dry tropics (drought and water scarcity)
Coastal plains, deltas and small islands (erosion, storm surges, sea level rise and salinization)
What migration happened after Hurricane Katrina?
internal migration from places like new orleans to Texas
What migration happened after hurricane Mitch?
Rapid migration from central america and mexico to US.
What happened during the mexico droughts to migration?
Feng et al. (2010) 10% decrease in agricultural production due to droughts led to an associated 2% rise in Mexico-US migration. This fed in to New Economics of Labour migration
What is household diversification and what is it linked to?
When a household decides to diversify the people part of it in to other sectors so that if one sector and therefore one family member is unable to provide income then the other family members will support them. Contrasting to if they all worked in the same job (e.g. family farm). This is linked to something called the New Economics of Labour Migration (NELM)
What might migration be dependent upon as well as climate change?
Sometimes people move knowing that if they move there will be economic opportunities elsewhere
What is step-wise migration?
Carrying out multiple steps to reach an end-goal migration destination. For example people might move intra to an urban area to enough money to move to a city where they can then earn enough money and skills to move to a new country where those skills are desired.
What is important to remember about migration as an adaptation strategy?
It is only one form of adaptation that is not available to everyone. However it could also not be an option desired by those people that have access to it or it may be the only option available for some
