• north-south water Transfer Scheme

  • adresses uneven water distribution
  • takes water from the south and supplies it to the north
  • Planned to be completed in 2050 - holds 44.8 billion cubic meters of water
• north-south water Transfer Scheme - advantages

  • reduces water security - supports economic develpment
  • improving food security
  • health benifits
  • improved water supply for industry’s
  • helps china deal with an image change
  • reduces groundwater withdrawal
• north-south water Transfer Scheme - disadvantages

  • 100,000 people displaced due to construction
  • ecological damage
  • region is earthquake prone - could damage the scheme
  • expensive - tax increase
  • antiques lost
  • lots of evaporation from canals and reservoirs
• sponge city

  • designed to be a solution for water scare and water logged cities
  • rain gardens, green roofs, constructed wetlands and permeable pavements to slow, capture and store rainwater - stored in an aquifer for later use
  • by 2030, 80% of urban area should be able to store their own water
• 3 gorges dam

  • Largest hydroelectric dam in the world - completed in 2009

  Chinese gov 4 goals for the dam:

  1. flood control - capacity of 22.15 billion cubic meters
  2. Power generation - to reduce dependency on coal
  3. Navigation
  4. Tourism
• strategies to manage Enviromental problems associated with economic growth

  • largest forest conservation programs in the world - response to deforestation, desertification and social erosion - natural forest conservation program (NFCP).
  • NFCP targets sensitive regions - significant degree of of degraded land over previous decades - monitoring forest cover between 2000-2010 - increase in forest cover of 1.6% of chinas land.
  • 4500km great wall of trees - started in 1978 - aim to complete by 2050 - non-ingenious tress planted dont store as much carbon, need more water and prone to more disease than the indigenous trees they replaced.
• Sustainability

  Meeting the needs of the present so that future generation can meet theirs.
• Dongtan eco city project

  • on Chongming island - near shanghai
  • chinas polluted cites have encourage the government to consider more eco-friendly cites for future generations
  • planned to run completely on renewables
  • dongtan will recover, recycle and reuse 90% of its waste
• Dongtan - energy and resouces

  • residents expected to recycle and rescue water
  • plans to generate energy through burning waste vegetable peelings
  • rain will be captured and cleaned to save water
  • Organic food produced on the island - prevents imports from far away
• Dongtan - genral facts

  • Will be 3/4 the size of manhattan
  • Located near Shanghai - mouth of Yangtze River
  • Chinese gov hope that it will become a lee print for future sustainable cities
  • will be ready for 10,000 people to move in by 2020 - expected to be completed by 2040
• Dongtan - buildings and transport

  • buildings close together - best use of space and easier to heat
  • houses completely insulated - prevents heat loss
  • networks of roads and cycle paths - encouraging residents to walk or cycle
  • solar-powered water taxis and buss around the island
• Dongtan - natural world

  • wetlands - provides habitats for many animals and plants
  • preserving wetlands = priority for city design
  • Farms will use nutrient city waste to grow crops
• Dongtan

  • limitations - many issues including political issues, undoing problems and Enviromental concerns
  • nothing has been built so far
  • positive - has inspired others.
