Rising Statelessness Due to Disappearing Island States
norm’. 97 Even if assuming that the government of a former island state would have
the consent of a foreign state to function on its territory, its effectiveness would
most probably eventually wane. 98 The importance of sovereign territory for a
government’s ability to operate effectively should not be undervalued. 99
Moreover, the aspect of independence should for the sake of completeness also
be mentioned here. Apart from the criteria illustrated above, the capacity to enter
into relations with other states and thus independence is also crucial to
statehood. 100 Independence in other words means inter alia that a state is
unaffected by the ‘factual dependence upon other states’. 101 Hence, it may not be
subject to the authority of a foreign state. 102 While it will obviously depend on the
host state whether governments in exile become subordinate, it seems rather
reasonable to conclude that a state without territory will find itself more easily in
dependency than other states. 103 Thus, it only seems plausible to assume the end
of statehood based on the criteria in the Montevideo Convention.
The ILA Executive Council established the ILA Sea Level Rise Committee in
2012 with the specific mandate ‘to study the possible impacts of sea level rise and
the implications under international law of the partial and complete inundation of
state territory’ and in this regard to ‘to develop proposals for the progressive
development of international law… including the impacts on statehood’. 104 In its
2018 final report, the ILA Sea Level Rise Committee poses the question whether
the problem of permanently uninhabitable state territory due to sea level rise would
eg require international law to recognise a new category of subjects in international
law, even if those entities lose their legal status as states. 105 Although international
law recognizes entities sui generis such as the Holy See or the Sovereign Order of
Malta for historical reasons, it seems rather unlikely that submerged states will be

and Emily Crawford, ‘Climate Change, Sovereignty and Statehood’, (Legal Studies Research
Paper No 11/59, Sydney Law School, September 2011) 8:
If the government of a state has been forcibly displaced from its territory through
belligerent occupation, the government in question is considered to remain the
legitimate government and state… Under international law, such exile must be
accepted by the international community; that is, there should be no general
acknowledgement of a change of circumstances.

For instance, McAdam argues that a merger with the organs of the host state would ultimately
lead to the extinction of the state if no other interests to uphold the continuance of statehood
prevail: McAdam, Climate Change, Forced Migration (n 29) 137.
It is important to keep in mind that disappearing island states would not only lose territory but
also their population. McAdam, Climate Change, Forced Migration (n 29) 160: ‘[A]
substantial loss of population would start to erode the effectiveness of the State’s government
as its economic base declined’.
