Water Quality in China Braden Rosenberg, John Gilbert, Kristen Underwood 29 October 2014, GEO 352 China’s GDP has increased 10% each year since the 1970s. 7 “The pursuit of economic growth has been the priority overshadowing the vital issues of water resources and ecological balance” 5. Outline • Water Resources of China • Brief History of Water Law & Policy • Project Profiles – Eutrophication – Mining – South-to-North Water Diversion Water Resources of China • • • • 7 % of world’s freshwater resources, but ~ 20% of world’s population 1 Water usage has increased 5-fold since 1949 (People’s Republic of China est.) 1 4/5 of water concentrated in the south 1 Population densities in the north and east 1 Nature, 2014 vol 511, issue 7511 http://www.nature.com/news/society-realizing-china-s-urban-dream-1.15151 Water Resources Per capita Renewable Water Resources in the 25 Most Populous Countries (x 1000 cubic meters per year) • 300 million people in China affected by water shortages 4 http://www.china-profile.com/data/fig_renewable-waterresources_1.htm Water Demand – major sectors Nature, 2014 vol 511, issue 7511 Agriculture (North Plain) Industry Domestic (urban centers) Water Demand Issues: Overpumping of Groundwater • e.g., North China Plain produces ½ of the country’s grain; groundwater aquifers have been overpumped leading to water table decline on the order of hundreds of meters 6 Diversion/Impoundment of water • e.g., 22,104 dams over the height of 15 m (2000) Ditching/ Wetland Loss Water Quality Natural contaminants Arsenic – 26 M people Fluorides – Dental fluorosis – Skeletal fluorosis – 25 M people Nature, 2014 vol 511, issue 7511 Water Quality 70% of China’s surface waters are polluted 7 Human contaminants • Agricultural runoff (fertilizers, pesticides, livestock waste)– algal blooms, eutrophication • Sediment • Septic waste • Heavy metals (e.g., As, Mn) • Radioactive wastes (thorium) • Petrochemicals Water Regulations – abbreviated timeline 9 • Environmental Protection Law • Est. 1989; broad environmental policy • Establishes “Polluter pays” principle • Environmental protection as a right and obligation for all citizens • Law on Prevention and Control of Water Pollution • est. 1984, amended 1996 • Implementation lacking, few incentives for enforcement • State council & local governments have implemented regulations to address water pollution • LPCWP amended 2008 • Stronger penalties for violators, • created discharge permit program • State / local governments continue to enforce local regulations • 1998 - State Environmental Protection Agency est. as a ministry level agency, following a year of devastating floods • 2008 – SEPA replaced by Ministry of Environmental Protection (MEP) Water Law & Policy Government Context 9 Effect on Regulation 9 • Unitary system –local level powers are only those delegated by the central government • Post-Mao reforms have eroded central government power over local-level subordinate bureaus • • • • • Multi-tiered system of regulation / enforcement Ministry for Environmental Protection (MEP) directs national efforts, while subordinate bureaus at the provincial, city, county, district, and town levels implement the national statutes and regulation Local environmental protection bureaus report to regional governments Regional governments receive tax revenues from industry (financial incentive to protect industry) Regulated industry often has direct personal ties to regional government Water Law & Policy Government Context 9 Effect on Regulation 9 • Parliamentary system, with President and Prime Minister • Civil law society – judges do not have authority to make or interpret the law • Communist Party has a parallel government structure • Prime Minister oversees MEP • Nontransparent decisionmaking; may limit public engagement Examples of Recent Progress • 2007 to present – EPA – China Environmental Law Initiative – • US EPA collaborating with Chinese MEP to establish and develop various environmental protection programs 2013 – National Standards on Environmental Protection in effect – e.g., air quality monitoring standards • Feb 2014 – MEP announces plan to invest $US 320B to address water pollution • Sep 2014 – World Bank approves loans totaling more than $US 500M to improve water and wastewater infrastructure in three rural and suburban 8 regions of China 7 Project Profiles Mining North-South Transfer http://www.worldatlas.com/webimage/countrys/asia/lgcolor/cncolor.htm Eutrophication 106:16:1 C:N:P Credit: Desert Research Institute Eutrophication effects: -Recreation -Fisheries -Microcystin -Coastal “dead-zones” Steady decrease in lake size throughout record 24,923 km2 50% of total area!
