Policy Briefs

Rates of urbanisation vary considerably among the 22 Pacific Island countries and territories, some of which have among the highest population densities in the world despite these countries being relatively small. Growth in the number of urban residents has led to the emergence of informal settlements on sites which are often on marginal land that is highly exposed to the effects of extreme events. It is likely that climate change will cause greater numbers of people to migrate to urban areas as their home locations become increasingly less habitable. Many will find themselves again living in exposed locations. Additionally, having little land tenure security, high levels of unemployment or underemployment, crowding, lack of infrastructure, crime and lack of access to land for food are likely to render many of these migrants vulnerable to the effects of climate change. As climate change continues to unfold, urban areas in the Pacific Islands region may find themselves particularly at risk. Urban planning which takes the likelihood of climate change into account is critically important.

The growth of urban populations in Pacific Island Countries is reflected in growing numbers of informal settlements with high levels of exposure and vulnerability to natural disasters. As urban populations grow and become increasingly dense, with large numbers living in informal settlements, the potential for major catastrophes is increasing. Despite this, most disaster risk management throughout the region still focuses on rural areas, reflecting historical practices and experience and some political preference for rural areas. There is a greater need in the region to develop measures that reduce people’s exposure to hazardous events in towns and cities, mostly by incorporating urban planning measures that discourage settlement in marginal and hazard-prone areas. This will be challenging given the complexity of land tenure arrangements throughout the region. It is also important that the root causes of people’s vulnerabilities are addressed, so that the processes by which they come to live in unsafe conditions can be understood and measures introduced to reduce people’s risks and losses. This policy brief focuses discussion on urban communities and concludes by outlining a number of activities which would contribute to reducing people’s exposure to hazardous events in Pacific Island towns and cities.
