Ineffective mitigation at the global level may result in a number of limits to adaptation for Saint Lucia, including the inability of coastal ecosystems to adapt to increased rates and extent of sea level rise; insufficient financial resources to implement required adaptation strategies; and lack of effective or affordable technology to provide coastal protection from impending sea level rise and extreme events. These limits to adaptation may result in loss and damage-impacts of climate change that occur despite the best mitigation and adaptation efforts. For Saint Lucia, loss and damage may affect all aspects of life, including loss of territory, damages to critical infrastructure, loss of income and livelihoods, decreased worker productivity and displacement and migration of communities p. 11

Potential climate change impacts on Sain Lucia's agriculture sector. Repercussions: Increasing rural-urban migration p. 24

Potential climate change impacts on Saint Lucia’s infrastructure and spatial planning sector. Repercussions: Potential migration and land use change, adding pressure on inland forest reserves to provide land for various uses as coastal land is lost to erosion and inundation p. 28

Potential climate change impacts on Saint Lucia’s education sector. Sea level rise impacts: Closures and relocation of coastal schools could cause major logistical complications for students and faculty to reach the new school areas (which could even be in other islands). Population displacement and migration would affect education continuity p. 30

Adaptation measure: Plan and initiate phased relocation of settlements and vital infrastructure to less vulnerable areas. Indicative outputs: Feasibility studies for the relocation of the most vulnerable settlements and vital infrastructure conducted. - Long-term relocation plans elaborated, discussed and approved. - Regulatory and enforcement mechanisms for relocation set-up. - Plan implementation initiated. p. 101

Potential loss and damage for Sain Lucia. Agriculture and Fisheries: Increaso in rural to urban migration. Infraestructure and spatial planning: Potential migration and displacement of coastal communities p. 129

Saint Lucia does not view migration as an acceptable adaptation strategy, and this is not included in its NAP. However, in the realm of limits to adaptation and loss and damage, Saint Lucia may wish to give consideration to collaboration with countries and organisations on proactive and context specific measures to avert, minimise and address displacement and planned migration of vulnerable communities. This includes: (i) developing and implementing policies that reduce the need for human mobility and/or effectively manage mobility to promote empowered migration; (ii) providing support and protection for internally displaced persons, persons displaced across borders and host communities; and (iii) providing support for the preservation or reestablishment of noneconomic values that may be impaired during human mobility p. 133.
