Climate Change in the Pacific: State of Emergency

As outlined in a previous post, “Climate Change in the Pacific:  Help we’re drowning,” Pacific islands are bearing the first clear environmental shifts of global climate change.  Not only are the islands being threatened by rising sea levels, their territory and societies ‘drowning’ in the process; but, climate change is combining with other environmental conditions to jeopardize the essential fresh water sources that these insular societies depend on.

On October 2011, the Pacific island nation of Tuvalu declared a national state of emergency.   The emergency is that the country’s fresh water sources are running out and others are unfit for consumption.  Some areas of the island were projected to completely run out of potable, fresh water within two days of the declaration.  The conditions that led to the state of emergency are related to the longer term climate changes, but also to seasonal shifts.  A seasonal, La Niña weather pattern has been causing drought in Tuvalu.  Below-average rainfall has been experienced since June or at least and is projected to continue into December.  Most of the country’s fresh water supply comes from collected rainwater.  Another source of freshwater lies under the ground.  Yet, this source is limited.  Tuvalu is a series of low-lying coral atolls.  The geology of coral atolls does not support deep groundwater sources.  Further, the shallow groundwater that is found on these islands is being compromised by rising sea levels as salt water infiltrates the groundwater supply.  A reporting of animals deaths leads Tuvaluan Red Cross officials to question the safety of the groundwater supply for consumption.  Considering the nature of groundwater recharge, and most acute in Tuvalu, the lack of rainfall is accelerating the infiltration of seawater into subterranean water features.  The impacts of water shortages are felt in the islands’ traditional subsistence agriculture activities as well as water rationing affecting basic water services.  Tuvalu’s neighbor and New Zealand territory, Tokelau followed up soon after with its own state of emergency declaration.

The relief is coming from international organizations like the Red Cross as well as from the government of New Zealand.  The people of Tuvalu and Tokelau are being aided with water collection supplies, desalinization units and plenty of bottled water.  The larger affects are still yet to come.  In particular, questions about the long-term settlement of many low-lying Pacific islands have implications for nationhood, cultural traditions, economic rights, and logistics of mass migration.
