The Imoact Of Human Activity On Coastal Landscaoe Systems

Question 1

Positive impacts of human activity

Answer 1

Adoption of sustainable management and conservation of coastal environments using soft engineering
Increasing use of integrated shoreline management strategies which consider all conflicting needs and constraints

Question 2

Conservation strategies

Answer 2

Vary in scale. And vary from total protection to allowing human activity.
World heritage sites
National marine reserves
Sites of special scientific interest

Question 3

Negative impacts of human activity of offshore dredging

Answer 3

Dredging is the extraction of sand and gravel from the sea bed for use in construction and increase shipping access.
Destroys sea bed habitats and marine food web
Changes wave types and sediment flows, can increase beach erosion if waves reach that far

Question 4

Negativity impacts of human activity of erosion of sand dunes

Answer 4

Sand dunes are fragile and vulnerable.
Conversion- dune area used for areas like golfing
Removal- sand removed for other use. Further erosion caused by wind.
Overuse - dunes used as an amenity for recreation activity, tourism etc, this leads to vegetation removal and wind erosion
External factors- human activity affects dunes, building sea defences reduces sediment input to dunes

Question 5

How can impacts to dunes be reduced

Answer 5

Compete reconstruction in heavily damaged areas
Restoration by reverberation and fencing to limit access
Removal of external factors

Question 6

How to manage the impacts of human activity on coastal processes and landforms

Answer 6

Integrated coastal zone management iczm
Iczm tries to balance economic social etc needs
It uses defence methods to enhance environment
Aims to meet current needs as well as future generation
