when undertaken without adequate resources. Water quality and availability are also
negatively impacted by climate change. Sea-level rise can result in the salinization of
fresh water sources, drought can reduce access to water supplies and flooding can
affect the quality of water. Health is tied to adequate food and water, and thus, where
access to these rights is limited, so too is human health. Migrants – and rural to urban
migrants, in particular – face increased disease and health risks from conditions in
slums and informal employment sectors.
34. Adequate housing is a component of the right to an adequate standard of living.
The right to adequate housing includes protection against forced evictions, security
of tenure, access to affordable housing, habitability and accessibility, and availability
of facilities, services, materials and infrastructure. 8 The right to adequate housing also
means that adequate housing must meet a number of criteria, including privacy, space,
security and location. People who are compelled to leave their homes owing to slow onset effects of climate change may face poor living conditions and, while in transit,
are likely to live in precarious conditions.
35. Slow-onset events of climate change, such as coastal erosion in areas of
Honduras, for instance, are exacerbating pre-existing poverty, inequality and
exclusion, compelling people to migrate. In this sense, t he absence of public policies
on prevention and mitigation, as well as a lack of environmental due diligence by
private companies, may be drivers that exacerbate these impacts on territories and
peoples. Likewise, the adverse effects of sudden-onset events linked to climate
change may have serious effects on subsistence in the territory, while they can also
accentuate dynamics of violence, insecurity and political persecution. 9
36. The adverse effects of climate change are placing existing environmental
systems, governance and social structures under stress. They are also increasing the
drivers of internal migration within Vanuatu, as people increasingly move towards
urban centres. Storm surges represent the highest displacement risk for Vanuatu, and
there is a 64 per cent probability that one will displace 10,900 people in the next 50
years. 10
37. The Special Rapporteur on the human rights of migrants notes that climate
change is challenging the adaptive capacities of many different communities and
overwhelming some owing to its interaction with and exacerbation of existing
problems of food security, water scarcity and the scant protection afforded by
marginal lands. The critical aspects are clearly varying from place to place and from
individual to individual. Natural disasters might displace large numbers of people for
relatively short periods of time; however, the slow-onset drivers are likely to displace
permanently many more people, those who can access migration as an adaptation
strategy, in a less headline-grabbing way. 11
38. It must be acknowledged that migration should serve as an important adaptation
strategy to climate change and a means to build resilience among individuals and
communities, while also reducing exposure and vulnerability to hazards. The Special
Rapporteur reiterates the analysis of his predecessor that migration has been a
traditional coping mechanism, widely used by populations around the world since
time immemorial to adapt to changing environments. If properly managed, migration
can therefore also be a solution to cope with climate change ( A/67/299).
