Straddling the equator in the middle of the Central Pacific Ocean, Kiribati is made up of 33 coral atolls spread across 3.5 million km² (1.3 million square miles) of ocean. Most of the islands are less than two kilometers wide and have an average height of 1.8 meters (6 feet) above sea level, making the country one of the most vulnerable in the world to climate change and sea level rise. With the entire population and the majority of the infrastructure located on the coast, damage and coastal erosion from high tides, storm surges, and strong winds are increasingly an issue.

King tides can wash over entire islands, causing flooding for days and contaminating drinking water supplies for weeks and even months. Through the Kiribati Adaptation Program, which is supported by the Global Facility for Disaster Reduction and Recovery and is now in its third phase, rainwater harvesting systems have now been installed in six communities in North Tarawa, Kiribati, providing a reliable – and safe – source of water.

North Tarawa, while still part of the main island of Kiribati, is only accessible by boat and remains largely subsistence-based, with residents gathering most of their food and water from their surroundings. Prolonged periods of drought, usually during La Nina years, often meant heavy rationing of water, impacting general wellbeing and agriculture. Until recently, communities used ground water from wells for all their cooking, drinking and farming needs. While usually satisfactory after boiling, ground water can become contaminated by seawater during floods and king tides, making people – especially children – sick. 

Ruteta, a mother of three living in Tabonibara village, North Tarawa, knows all too well the problems that contaminated well water can bring. “A few years ago our well water got really smelly. We worried about our children, because they had diarrhea after drinking the water we boiled from the affected well,” said Ruteta.

Infant mortality in Kiribati is the highest in the Pacific Islands, at 43 deaths per thousand live births. Infantile diarrhea contributes to this high number.

“Now that we have rainwater tanks our children have fallen ill much less so that makes us very happy. There’s a big difference in the quality of rainwater compared to well-water,” said Ruteta.

Rainwater harvesting systems were piloted in an earlier phase of the Kiribati Adaption Project and, after extensive consultations with local authorities and community members, the project’s team was able to design the systems, decide on the best building and locations (to be retrofitted with gutters and piping to help catch rain and direct it to the tanks), and work with each community to establish operation and maintenance committees, who are responsible for the systems and their maintenance.

“There [are] around 50 pumps on our island of North Tarawa,” said a local Government Water Technician working on the project. “The water goes straight to the tanks where it will be stored and shared among the people for the wellbeing of the people. The community will decide on how to ration the water during times of drought.”

With the rainwater harvesting systems in place, community members now have easy access to clean water, and the storage tanks mean a larger pool is available during times of drought.

“We are grateful because life is much simpler having rainwater,” said Ruteta. “When a drought comes in the future, we will be reassured that we will have drinking water stored in the tanks that we can get directly from those taps and we are happy that we won’t be in trouble.”

In its Policy Statement on Climate Change, the Government of Kiribati says: “As Kiribati cannot escape climate change, it must adapt to it.”

With that in mind, the Kiribati Adaptation Program, in place since 2003, focused first on raising awareness of the impacts and incorporating climate change into government policies, then on piloting mangrove planting and construction of seawalls.

These rainwater harvesting systems are just one of the activities being undertaken to help Kiribati better prepare and withstand climate related impacts in the future. Key coastal areas are now being protected through locally-managed adaptation plans, identifying vulnerable areas or infrastructure and mapping out ways to maintain or protect it, with small grants for activities around climate change adaptation and disaster risk reduction, together with technical support for the government’s Strategic Risk Management Unit, which oversees this work.

The Kiribati Adaptation Project and its activities are supported through the World Bank; the Governments of Australia, Japan, and Kiribati; and the Global Environment Facility, in addition to GFDRR.
