Climate disasters challenge right to safe and adequate housing

Climate disasters displace millions of people each year.

In 2023, the figure reached 26.4 million worldwide as a result of floods, storms, wildfires and other disasters, according to the Internal Displacement Monitoring Centre (IDMC).

Climate change is not solely responsible, but the frequency and intensity of extreme weather is increasing as global temperatures continue to rise. As a result we can expect that more and more people will face losing their homes and their livelihoods.

It is commonplace to see people boarding up their homes and literally battening down the hatches before a major hurricane is predicted to make landfall. For those facing extreme weather, this mentality is no longer confined to one-off events, but a regular mindset as the climate crisis continues to bite. Many communities around the world know that building resilience against intense storms, floods and heat waves is now essential to daily life.

“No country is immune to disaster displacement,” Alexandra Bilak, IDMC’s director, said in a recent press statement. “But we can see a difference in how displacement affects people in countries that prepare and plan for its impacts and those that don’t. Those that look at the data and make prevention, response and long-term development plans that consider displacement fare far better.”

This kind of planning is happening in countries on the front line of the climate crisis. Some small island nations, for example – many of them low-lying – are seeing their homes permanently washed into the Pacific Ocean.

Paradise lost

According to Fiji’s government, disaster events in the Pacific island state over the past 40 years have led to annual economic damages of around US$16 million, with 40,000 people impacted each year. This is due to increase to an average of US$85 million per year in losses, as a result of cyclones and earthquakes. These figures are high for a country with a population of under 1 million people.

Many of the people most impacted by climate disasters live in informal urban settlements. Their homes are extremely vulnerable to the regular cyclones that hit the island nation, especially as they are often located near riverbanks or around the coast.

The subtle art of scaling up climate adaptation

A recent Adaptation Fund project in Fiji was designed to build resilience against regular extreme weather events and “climate proof” housing for the foreseeable future. The project, implemented by UN-Habitat, looked at ways to protect thousands of homes when storm surges overwhelm local water and sanitation infrastructure. The settlements were located across four main urban areas on the island: Lautoka, Sigatoka, Nadi and Lami.

Low-cost, high-impact

Constructing cyclone-resilient buildings was an essential component of the work.

Moving new homes away from vulnerable hot spots, such as foreshores, floodplains and riverbanks, was a first step. As many settlements are self-built, training local people in new construction methods ensures future homes can be built with extreme weather in mind. An innovative element from the project was so-called ‘stilted safe rooms’ – low-cost and simple raised structures intended to provide refuge during periods of intense flooding.

Flood control is a key component of climate-proofing infrastructure. In Fiji, priorities included building upgraded site drainage to reduce runoff; upgrading water sources and storage; and improving access ways, to ensure people can respond when cyclones put pressure on local infrastructure.

School’s out

In Haiti, a very poor and conflict-torn country beset with repeated natural disasters, climate-proofing infrastructure is still at an early stage. The country’s education sector, for example, has been repeatedly hit by extreme weather, including in 2016 when Hurricane Matthew damaged a quarter of its schools. Rebuilding after such frequent turmoil now requires new ways of thinking.

With the help of around US$10 million of funding from the Adaptation Fund, UNESCO is currently supporting the restoration of 620 schools across the country. Their work has included raising awareness of disaster risk reduc
