🐟 Marine Protected Areas — A Patchwork of Progress

Marine Protected Areas (MPAs) restrict human activity (fishing, mining, tourism) in defined ocean areas to allow ecosystems to recover and protect biodiversity. In polar regions, they represent the most direct tool for managing marine exploitation — but progress has been slow and contested.

Ross Sea MPA (2016) — A Landmark Agreement

Established in October 2016 under CCAMLR after 5 years of negotiations — the longest in CCAMLR history

Covers 1.55 million km² of the Southern Ocean — the world's largest MPA at the time of designation

Restricts fishing in 72% of the area; special research zones in the remaining 28%

Protects one of the last pristine large marine ecosystems on Earth: Ross Sea supports large populations of emperor penguins, Weddell seals, Antarctic toothfish, and orcas

Limitation: The agreement has a 35-year term — it can be reviewed after 2051. Given the pace of climate change and resource pressure, 35 years may be inadequate for the ecosystem to fully recover and establish resilience

Russia and China delayed the agreement for 4 years — both opposed restrictions on toothfish fishing; the eventual compromise allowed limited fishing in designated research zones

Proposed East Antarctic MPA — Still Blocked

A proposed East Antarctic MPA (1.93 million km²) has been under negotiation since 2012

Repeatedly blocked by Russia and China at annual CCAMLR meetings, primarily on the grounds that CCAMLR lacks the mandate to establish MPAs (a contested interpretation)

The failure to agree on the East Antarctic MPA illustrates the fundamental weakness of voluntary international governance: any single nation can veto progress indefinitely

Arctic MPAs — Minimal Coverage

The Arctic lacks any equivalent MPA framework to CCAMLR; the Arctic Council has no binding authority

The Central Arctic Ocean Fisheries Agreement (2021) — signed by 10 nations including China, the EU, Russia, and USA — bans commercial fishing in the Central Arctic Ocean for at least 16 years while scientific assessments are conducted; a significant step but limited in scope

Practice questions for Cold Environments — Threats & Management

C. The greenhouse effect
D. Ice albedo feedback

Quick recall flashcards

What is the ANWR debate in Alaska?

The Arctic National Wildlife Refuge contains an estimated 7.7 billion barrels of recoverable oil. The debate is whether to drill (economic benefit, energy security) or protect the sensitive ecosystem (caribou, polar bears).

How much has Antarctic tourism grown?

From fewer than 5,000 visitors in 1990 to approximately 74,400 in 2019–20 — mostly on cruise ships. This rapid growth threatens fragile ecosystems.
