China’s Environmental History: China’s Environmental History 600 AD: overpopulation in areas, migration in search of arable land, better water resources
1400 AD: 100 million people
Mao’s Culturul Revolution:
Back yard steel furnaces
Industries moved to the countryside for “protection”
Deforestation for agriculture
1978 Open Door Policy - Today: accelerated economic growth has accelerated the problems
Minestry of Water Resouces, Jiang Dewen, 2004 :: Minestry of Water Resouces, Jiang Dewen, 2004 : “Fast economic and social development requires large-scale infrastructure construction, which has affected the natural environment.”
“The conflict between economic development and natural resources has become very pronounced in China.”
Overview of Environmental Issues: Overview of Environmental Issues Deforestation
Land Degradation
Air Pollution
Water Contamination
Deforestation: Deforestation Local forests have long served as firewood in rural areas, and lumber in construction and furniture making
Forests are currently in danger from the increased demand for paper
China’s forests: 17% of total area
US forests: 25% of total area
Canada: 46% of total area
Deforestation: Deforestation 50% of loss: conversion to settlements
50% of loss: logging
Forest loss in China is about 4 – 6% per year
Deforestation - Consequences: Deforestation - Consequences Accelerated soil erosion and flooding
Increased amount of sediment that accumulates in reservoirs and deltas
Dust storms, desertification
Land Degradation – Soil Erosion: Land Degradation – Soil Erosion 37% of China’s land area is affected by soil erosion (3.56 million sq km)
Every year, about 5 billion tons of soil lost
Yangtze River: Yangtze River Longest river in China, and third longest on Earth: 6,300 km long
41.1% of the river basin area (740,000 sq km of land) suffers from soil erosion problems
Every year, the river basin loses 2.24 billion tons of soil
Yangtze River: Yangtze River Experts in the area say that soil erosion has become a “big headache” for social and economic growth in the surrounding area
Case Study – Loess Highlands Project: Case Study – Loess Highlands Project Located in northwest China
In 1994, a conservation program in Loess Highlands was launched using loans from overseas financial institutions
Loan from the World Bank of 2.1 billion yuan (US $150 million)
Case Study – Loess Highlands Project: Case Study – Loess Highlands Project Brought 4,843 sq. km of affected area under control in 22 counties
Annual grain output increased from 430,000 tons to 700,000 tons currently
Net income of local peasant farmers increased threefold, to 1,263 yuan (US $152)
Air Pollution: Air Pollution 16 of the world’s 20 most polluted cities
4 million deaths per year
300,000 premature deaths due to respiratory diseases
Air Pollution - Transportation: Air Pollution - Transportation Fastest growing auto market in world
2 million cars sold in 2003
80% increase over 2002
Cars made by China companies in cooperation with foreign car manufacturers (e.g., BMW and Audi)
Air Pollution - Transportation: Air Pollution - Transportation
Air Pollution - Transportation: Air Pollution - Transportation Average emission rate per vehicle is very high
CO and NOx
Big step back
New fuel efficiency standards
27.5 miles per gallon in 2007 (higher than current US standards)
Implementation???
Air Pollution - Transportation: Air Pollution - Transportation China is the world’s second largest consumer of oil
Oil use expected to grow 13% this year
Growing demand industry and car ownership
Chinese Gas Station
Air Pollution - Energy Generation: Air Pollution - Energy Generation 70% of energy produced from coal
SO2 Pollution and acid rain
Growing demand
Goal: 10% of energy from renewable resources by 2010
Water Shortages: Water Shortages Growing demand
Per capita supply is 25% global average, most is in South
60 million find it difficult to get water for their daily needs
Relocation of thousands along coasts
“Cloud seeding” during droughts
Water Pollution: Water Pollution Pollution from industrial waste water
70% of the water in 5 major river systems is unsuitable for human contact
700 million drink contaminated water on a daily basis
Almost 20% of agriculture and poultry in industrial / mining districts contain excess contamination
Communities along the major river system report high rates of cancer, tumors, stunted growth, spontaneous abortion and diminished IQs
Case Study- Shangba, “cancer village”. : Case Study- Shangba, “cancer village”. Gov’t owned mineral mine and smaller private mines dump toxic waste into local rivers
Lead 44x permitted rates
Rice yields 1/3 nat’l ave, incomes 1/3 province ave.
One woman needs new kettle each month because water corrodes the metal
Local reservoir solution dropped because of 8.4m yuan cost
Current Issues: Current Issues Three Gorges Dam
2008 Olympics
Three Gorges Dam - Background: Three Gorges Dam - Background Dam on Yangtze River in Hubei Province
Originally proposed in 1919
Premier Li Ping gained legislature’s approval in 1992
Will be completed in 2009
Three Gorges Dam - Logistics: Three Gorges Dam - Logistics Functions: flood control, power generation, improved navigation
Cost: 24.65 billion US$
Over 600 feet tall
Over one mile long
Largest hydroelectric dam in world
Three Gorges Dam - Benefits: Three Gorges Dam - Benefits Cleaner energy production
Capacity = 18.2 million kilowatts
Equivalent to 18 nuclear power plants
1/9th of total production
Flood control
Over 1 million people have died from floods in the past 100 years
Navigation
Increase in freight transport to interior, agricultural center
Three Gorges Dam - Costs: Three Gorges Dam - Costs Water Pollution
Accumulation of toxins within reservoir
Ecosystem, biodiversity losses
Project requires extensive logging
Resettlement because
1.9 million people Less fertile land
Inundation of 100 towns, 1300 archaeological sites
Corruption, spiraling costs, etc.
Three Gorges Dam – Present Situation: Three Gorges Dam – Present Situation 80 cracks, 2.5 meters in depth (by 2003)
Beginning to fill reservoirs and generate power
Reservoir will be completely full in 2009
2008 Green Olympics: 2008 Green Olympics Wastewater treatment improved
Grass planting to fight desertification and “Green Great Wall”
Stricter emissions standards
Polluting industries relocated or converted
Coal burners converted
Air quality improved 34% over 1998
2008 Green Olympics: 2008 Green Olympics Effects of debt on
environment
Relocation of industries
to where?
Effects on countries supplying materials
Efforts to maintain a green Beijing after the Olympics
Effects of massive infrastructure after the Olympics
Perceptions: Perceptions Lack of understanding of concept that the “polluter should pay”
Short term vs. long term goals
Mao: Man must “conquer nature and thus attain freedom from nature”
