In Solomons, Seas Rising Fast - 8mm/Year Since 1993
EDIT
The sea level near the Solomon Islands has risen by 8 mm per year since 1993, compared to the global average of 2.8-3.6mm, according to the Pacific Climate Change Science Programme. The prediction is that by 2030 the sea could rise by a maximum of 15 cm, the average wind speed of cyclones could increase by up to 11 percent and associated rainfall intensity by 20 percent.
Caspar Supa, coordinator of the Pacific Adaptation to Climate Change Programme (PACC) in the country told IPS that places on the frontline were the artificial islands, low-lying atolls and the low-lying areas of larger islands where “there is low food security, lack of development, small resources and limited education about climate change.”
On Malaita Island, approximately 12,000 people live on artificial islands in Langa Langa Lagoon on the west coast and Lau Lagoon on the northeast coast. Thirteen islands can be found in Langa Langa Lagoon, which is 21 km long and a kilometre wide.
In spite of the tradition of oral history many, including Waleronoa, do not know the exact reason their ancestors created these unique environments, where communities are renowned for fishing, shipbuilding and traditional ‘shell money’ manufacture, but some believe it could have been the consequence of disagreements or estrangement from mainland villages.
