3.2 Protecting Antarctica Flashcards
Give an overview of the things which protect Antarctica
Adaptation and Resilience
Governmental mitigation
NGO and SCAR mitigation
Define Adaptation
An adjustment in the structure of an organism/system to enable better survival in a changed environment
Define Resilience
The amount of disturbance an ecosystem can withstand without changing.
For example, the ability to recover from shock events or ongoing change, and is closely linked to adaptation
Define mitigation
Strategies undertaken to stop a changing environment
What kind of species are the most resistant to shock events
Endemic species
Give examples with context, of an Antarctic animal which has adapted
Emperor penguins
Average depth of 200m
Dense double layer of feathers
Large fat reserves
However, there has been a 50% decline in certain colonies due to climate change
Give examples with context, of an Antarctic animal which were resilient
Adélie penguin
In 2001, an iceberg the size of Jamaica carved off the Ross Ice shelf, forcing them to move 70km north. However, once here, there was an abundance of krill, and they have actually increased 20%
What are the threats to penguins in Antarctica
Overfishing and Climate change…
1. Increased natural shock events like ‘scouring’
2. Increased sea temperatures effect sea ice
3. Ocean acidification
What is the main remedy for international governance in Antarctica
The Antarctic Treaty
(ATS, Madrid, IWC)
One of the most successful international agreements
Why was the Antarctic treaty made
In the 1950’s, permanent and territorial positions were asserted on the continent, but not agreed, creating tensions between scientists.
It was initially made to resolve these disputes and establish development guidelines
When was the Antarctic treaty signed
In 1959, sovereignty had been solved, and 12 nations signed the treaty, allowing it to come into place 1961
Give examples of the Antarctic treaty’s 14 articles
- It is to be used exclusively for peaceful purposes (no military etc)
- Freedom of scientific research, as long as research is freely available, and they give notice to expeditions
- Inspection of any activity
- Dispute settlement procedure
What did the Antarctic treaty develop into and how many members does it now have
The Antarctic treaty system (ATS) hosted by the ATCM
It has 46 signatures, as any UN member is allowed to accede
What does the AT system comprise of
Complexity of arrangements to regulate relationships between nations, while also controlling their antarctic actives
What did the ATS add to the antarctic treaty, and what has this expanded the 14 articles to
- The Madrid Protocol
- The conservation of marine living resources and Antarctic seals
- Allows NGO’s and SCAR to input
The articles now also include the protection of the environment, historical sites, tourism and logistics
