Workshop on the World Ocean Assessment

Part 6: Factors Affecting Environmental Values – Threats/Pressures (continued) River discharges Environmental Impacts: freshwater plumes, water extraction for agriculture, dam-building, sediment loads, pollutant loads, nutrient loads, on nearshore reefs, fish stocks, seagrasses, etc

(Identify the assets/values from P1- P5 that are affected)

( Identify the social & economic assets/values affected) e.g. navigation channels, coastal stability, foreshore erosion, flooding/drowning of lowlands, etc (Identify the assets/values from P1-P5 that are affected)

Social & Economic Impacts

Coastal Wetland Conversion

Environmental Impacts: loss of natural habitats – saltmarshes, mangroves; loss of coastal protection, loss of carbon sinks/sources, loss of useful connections with other ecosystems, potential release of unwanted gases (methane, H2S), Introduction of unwanted species,… Social & Economic Impacts Introduction of pests, diseases, shift in livelihoods, loss of information and cultural sources,… Environmental Impacts: loss of natural habitats, change in hydrology, change in sediment cycling to and from beaches, modification of natural hydrology, increased water turbidity and nutrients, destruction of donor sites, loss/reduction of biodiversity, offsite pollution Social & Economic Impacts Increase in number of illegal households, shift in livelihoods, decrease/increase in land value Environmental Impacts: Terrestrial infrastructure and access, channels and designated port ownership/vesting of coastal waters, sea dumping, change in hydrology, oil/fuel spills

(Identify the social & economic assets/values affected)

Land Reclamation

( Identify the assets/values from P1- P5 that are affected )

( Identify the social & economic assets/values affected ) ( Identify the assets/values from P1- P5 that are affected) ( Identify the social & economic assets/values affected ) e.g. contamination of seafood, loss of fishing grounds, interference with aquaculture sites, increased risk of oil spills and groundings that affect fishing and aquaculture ( Identify the assets/values from P1- P5 that are affected ) ( Identify the social & economic assets/values affected ) e.g. loss or contamination of fishing grounds ( Identify the assets/values from P1- P5 that are affected ) ( Identify the social & economic assets/values affected ) e.g. loss of subsistence fisheries, decrease in CPUE, serial depletion of valuable species, etc.

Port facilities

Social & Economic Impacts Increase in number of illegal households, shift in livelihoods, decrease/increase in land value

Oil and gas exploration and production

Environmental Impacts: Seismic surveys, drilling, platforms, pollutants, oil spills,..

Social & Economic Impacts

Fishing

Environmental Impacts: Impacts of live-fish fishing, trawling etc on harvest on population size and structure, impacts on non-target species, impacts on habitat
