    • The introduction of coastalinfrastructure as a driver ofchange in marine environmentsBy Fabio Bulleri and Maura G. ChapmanPresented by:Xianbin Liu and Laura FidalgoCourse: Coastal Environment – CIAM 6117Department of Environmental ScienceUniversidad de Puerto Rico, Rio PiedrasThursday, September 27, 2012
    • Introduction Problem – Diffident ecological – Human settlement near shore impact studies (75% by 2025) – Major tourism destination – Impacted coastal landscape – Alteration of intertidal zone and nearshore estuaries and marine waters habitat  Homogeneous topography affects species interactions  Unnatural Material affect colonization  Fragmentation
    • Introduction Objectives – Summarize the ecological impact of urban infrastructure on marine habitat know today – Discuss the implication of alternative coastal defense options – Identify the direction of future research
    • Urban Coastal Infrastructure Breakwaters – Reduce the intensity of waves in inshore waters – Decreases nutrients input and waste wash off – Changes marine life distribution
    • Management Alternative Incorporating into shoreline stabilization natural elements: – Wetland Vegetation – Seagrasses – Coarse Woody Debris – Shellfish Reefs – Coral Reefs Reduces ecological impacts without impinging on their efficacy in halting erosion.
    • Urban Coastal Infrastructure Groynes – Reduce along-shore transport of sediments
    • Management Alternative Small size groynes are less detrimental to shore sediment movement. Sand dunes – Protect beaches from erosion and recruit sand to eroded beaches.
    • Urban Coastal Infrastructure Jetties – Reduce wave- and tide-generated currents – Affects intertidal organisms biodiversity
    • Management Alternative Better collaboration among engineers, managers and ecologists to develop improved ways of building infrastructure. Provide habitat for more species without compromising engineering standards.
    • Urban Coastal Infrastructure Seawalls Bulkheads – Reduces the impact of waves on shore – Does not support natural communities assemblages – Increases steepness of shore – Deeper nearshore waters
    • Management Alternative (a) Intertidal ‘rock- pools’ constructed in the vertical face of a seawall in Sydney Harbour (Australia). Mitigates effects of loss or degradation of rocky platforms on intertidal biodiversity. (b) Rock-pool retaining water during low tide.
    • Urban Coastal Infrastructure Pilings – Sustain infrastructure, such as bridges, piers, docks – Shading and seafloor proximity affects communities assemblages (Glasby, 1999)
    • Management Alternative Height, orientation, and width of docks, piers, and bridges may reduce impact to vegetation productivity (Shaefer, D. and J. ( Lundin, 1999).
    • Urban Coastal Infrastructure Floating docks – Creates boating facilities – Shading consequences:  Decrease benthic productivity  Decrease carbon/nitrogen content  Changes in physical characteristics in sediment underneath – Affects Epibiota Structure
    • Urban Coastal Infrastructure Ropes-poles/cages- nets – Constituents of aquaculture facilities – Marine water pollution
    • Management Alternative Onshore fish farms are the most sustainable types of aquaculture. – the self-contained systems do not pollute the marine environment.
    • Future directions forresearch How fundamental ecological processes are affected Ecological interaction on artificial structures Ecological engineering
    • Concluding remarks Urban marine novel ecosystem need a closer understanding – Sustaining biodiversity – Successful conservation and management – Mitigate human coastal development and climate change effects
