Pacific Regional Energy Assessment 2004 : an assessment of the key energy issues, barriers to the development of renewable energy to mitigate climate change, and capacity development needs to removing the barriers : Kiribati National Report / Herbert Wade; Peter Johnston

Abstract

The climate is maritime equatorial with temperatures changing little over the years. Daytime averages are in the thirties and night time averages in the twenties. Rainfall varies from north to south with the Phoenix group in the south particularly dry with only around 800mm per year while the northernmost islands receive as much as 3000 mm/year. All of Kiribati, but especially the Line Islands, are affected by the El Nino/El Nina cycle (ENSO) and suffer cyclic droughts. Winds are moderate, seasonal and variable. Cyclones are not a problem in Kiribati with extended droughts the primary natural hazard. Rainwater is the main source of potable water with brackish atoll lens water often used for washing. South Tarawa provides piped water sourced from the atoll fresh water lens and appears to be near the limit that can be pumped from the lens without salt water encroachment. Kiribati is a signatory to most treaties and conventions relating to environmental protection and has a special interest in climate change prevention since even a modest rise in sea level endangers the low lying atoll islands.
