Q

What is the Case Study for RELICT LANDSCAPES?

A

Lake District

22
Q

RELICT LANDSCAPES: What are threats to the Lake District?

A

Footpath erosion, farming on upland areas, water storage/forestry

23
Q

RELICT LANDSCAPES (footpath erosion): How many visitors does the LD get?

A

16 million visitors a year over 2000 miles of footpaths.

24
Q

RELICT LANDSCAPES (footpath erosion): How does these visitors effect the landscape?

A

walkers destroy vegetation, compact soil, reduces infiltration rates, exposes soil that is washed away, gullies form, widen paths, less nutrient rich particles

25
Q

RELICT LANDSCAPES (footpath erosion): What has been done to reduce this threat?

A

LD national park authority (LDNPA) repair over 40 years, rangers use techniques but is slow and expensive

26
Q

RELICT LANDSCAPES (farming on upland areas): Where is used for sheep grazing?

A

fell tops over 600m

27
Q

RELICT LANDSCAPES (farming on upland areas): How does grazing threaten the landscape?

A

degrade land, erosion, threaten landscape due to roaming freely.

28
Q

RELICT LANDSCAPES (farming on upland areas): How does farming threaten landscape?

A

on valley floors produces lots of energy

29
Q

RELICT LANDSCAPES (Water storage/forestry): How does water threaten the landscape?

A

Thirlmere dam flooded small Hamlet/pub/restaurant, more water needed from aqueduct to support more people

30
Q

What is the case study for a GLACIERS?

A

Sagarmatha NP

31
Q

GLACIERS: What are the threats to the Np?

A

Tourism, Natural causes/disasters, Climate/everest

32
Q

GLACIERS (tourism): How many people visit the area in 2014?

A

over 37,000, which increases demand for energy and erosion/water pollution

33
Q

GLACIERS (tourism): Due to increased temps, in 2013 how much did glaciers shrink by?

A

13% in 50 years, influences sherpa people

34
Q

GLACIERS (natural causes/disasters): In 2004 what hit the NP?

A

28 mag earthquake, as tectonically active, which degrades the environment

35
Q

GLACIERS (Climate/Everest): How many people have now reached Everest’s summit?

A

over 6000 and 90% guided, causing pollution, rubbish, crowded, and travel causes gg

36
Q

GLACIERS (Climate/Everest): By how many m is the snowline higher than it was 50 years ago?

A

180m higher, causes floods/glacial outbursts
