6 Selected River Deltas Globally East China Sea South China Sea THE most densely populated areas on Earth

7 Characteristics and Advantages of River Deltas Productive arable land Marine and river resources for protein food security Often onshore and offshore oil and gas A flat topography, eases settlement Ice free harbours Sweet water availability from river and aquifers Rich biodiversity, Eco-tourism KUENZER C. and RENAUD, F. 2012: Climate Change and Environmental Change in River Deltas Globally. In (eds.): Renaud, F. and C. Kuenzer 2012: The Mekong Delta System - Interdisciplinary Analyses of a River Delta, Springer, ISBN: , DOI / , pp. 7-48

8 Ecosystem Services of River Deltas as the YRD Provisioning services: Freshwater supply Fisheries Supporting services: Carbon sequestration Soil formation Regulating services: Flood and drought regulation Water purification Cultural services: Recreational value

9 Population Density in Chinese Deltas Population Density within and outside of a 10 meter low elevation coastal zone (LECZ) in the year Source: CIESIN Centre for International Earth Science Information Network, Columbia University

10 Urbanization causing Change Waste water-, and solid substance pollution Loss of natural wetland areas (filters / buffers) Heavy structures, ground water pumping, drilling of oil and gas: land subsidence (increased flood danger) Upstream dams depleting the supply of sediments to many deltas: coastal erosion Yellow Rhine Tokyo Slide 10

11 Agricultural Intensification causing Change Increased application of fertilizer, pesticides, antibiotics Shift towards most profitable monoculture crops (e.g. cotton) decreasing biodiversity Intensification of aquaculture close to coast, leading to depletion of protective zones (mangroves, forest) Danube Mekong Yellow Slide 11

12 Climate Change Impacts in River Deltas (SLR) Source: IPCC 2007

13 Delta Urbanization & Transformation: Drivers of Risk Land Delta Land-Ocean Transition Zone Ocean migration of the population river salinized areas water pollution groundwater pumping industrial pollution pollution urban sprawl heat island effects water logged areas need for protective dykes increased flood danger increased danger of storm surges & landfall sea level rise up to 50 cm till 2050 algal blooms decreasing harvest due to limited salt tolerance (e.g. rice, corn) land subsidence due to groundwater pumping & compaction salt water intrusion into aquifers
