Water Case study: Water insecurity in the Aral Sea Flashcards
Context
- Once world’s 4th largest inland sea - Aral Sea had been steadily shrinking since 1960s
- By 2007, sea had declined to just 10% of its original size, split into separate lakes and fallen up to 40m
Why such a shortage?
- Late 1950s Soviet govt diverted much of water from rivers Amu Darya and Syr Darya - fed into Aral Sea
- This done for irrigation and agriculture
- Late 1950s Soviet govt diverted much of water from rivers Amu Darya and Syr Darya - fed into Aral Sea
What did the former Soviet Union government do about it?
- Communist leaders began an ambitious irrigation scheme designed to develop fruit and cotton farming in what has been an unproductive region and create jobs for millions of farm workers
Impact on fishing community
- once prosperous industry employing 60,000 people in surrounding villages had collapsed
- Unemployment and economic hardship are everywhere.
- Ships lie useless on the exposed seabed
Impacts on local residents
-health problems caused by wind-blown salt + dust from dried out seabed
-health problems caused by wind-blow salt + dust from dried out seabed
drinking water and parts of remaining sea become heavily polluted result of weapon testing, industrial projects and pesticide/fertiliser runoff
-infant mortality rates among highest in world, 10% of children dying in their first year, mainly of kidney failure and heart failure
Uzbekistan government
irrigation schemes based on Aral Sea allow this poor country, with few resources, remain one of worlds largest exporters of cotton
Scientists
- Only 160 of the region’s 310 bird species, 32 of the 70 mammal specie and very few of the 24 fish species remain
- climate changed as well + area more arid and prone to greater extremes of temperature
Kazakhstan farmers
irrigation brought water table to surface, making drinking water and food crops salty and polluted
international economists
- people in region may no longer be able to feed themselves due to land becoming infertile
- up to 10mil people maybe forced migrate + environmental refugees
Water engineers
inspections revealed many of irrigation canals were poorly built = allowed water to leak out or evaporate
