water and carbon case study

• indonesia- population of 262.7 million( growth rate 0.83%)
• second heavily forested area in the world behind the amazon
• indonesia

  has a gdp of $3.25 trillion
• indonesia agriculture products examples

  rubber, palm il, poultry, cocoa, coffee
• indonesia life expectancy is 73.2 years
• indonesia

  deforestation rates are up due to the plantation of palm oil
• river wey

  formed by two main branches wey north and wey south
• river wey

  in the wey valley there are gentle sloping valley sides with larger flatter plans towards the thames
• river wey

  is used to withdraw 44 million gallons of water per day by abstraction licenses
• river wey reasons for flooding

  1. steep valleys inwards towards the river
  2. urbanisation
  3. reduction in vegetation
  4. high rainfall
  5. river flooded fast
• river wey impacts

  1. 2013-2014 was the wettest winter and caused 12 major storms in 3 months
  2. 50000 homes without electricity
  3. 150 properties flooded
  4. effected 30+ flights
• river wey management

  1. flood defences to protect highways and infrastructure
  2. regeneration of flood risk management measures
  3. temporary barriers put up in areas with high flood risk
  4. created flood storages to divert flooding
  5. £1 million spent on increasing river storage ( removed sediment from the river bed)
• indonesia impacts of deforestation

  1. 1 million+ hectares lost every year
  2. peatlands exposed which are easily eroded turning carbon sinks into carbon sources
  3. burning of forest releases lots of carbon- 85% of carbon emissions come from the forest
• indonesia general impacts

  1. photosynthesis greatly reduced
  2. respiration greatly reduced
  3. decreased evapotranspiration
  4. decomposers largely absent
