    Country: Cook Islands Location within the country: Project sites are - Rakahanga, Manihiki, Nassau, Pukapuka and Penrhyn Project type: Type 2 Total requested budget: EURO 400, 000.00 Duration of project: 3 years Contact point: 1. Ms Ana Tiraa Email: [email protected]; Climate Change Cook Islands 2. Mr. William Tuivaga Email: [email protected]; Climate Change Cook Islands Project title: Northern Water Project (Phase 2) Background and rationale; The Northern islands of the Cook Islands (Pukapuka, Nassau, Penrhyn, Manihiki and Rakahanga) are low lying atolls and are therefore highly vulnerable to the impacts of natural disasters and climate change. During the 2004-05 cyclone seasons for the Cook Islands, the northern islands sustained significant destruction to infrastructure including substantial damages to community and household water catchments. In response, the Cook Islands and New Zealand Governments implemented the Northern Group Rain Water Harvesting Project. The project repaired household roofs, installed domestic water tanks and new spouting, and provided training in water safety and tank system maintenance. This increased the capacity for rainwater storage at the household level. However, the community water tanks on these islands are yet to be repaired. Repair and restoration of these water tanks will provide an additional 2,497,000 litres of water to the communities on these islands. Although this is deemed a priority for Government, tight fiscal conditions has hampered progress. Repairing these community water tanks will improve water security for the northern islands. In doing so, enhance the resilience of these islands to natural disasters (including drought proofing) and strengthen disaster management capabilities aimed at increasing capacity for rainwater harvesting and storage.

    Cook Islands Introduction The increasing presence of plastic marine debris in the South Pacific Ocean is focusing attention on strengthening recycling policies and systems in the region. Unique challenges associated with shipping commodities of low value over long distances to recycling markets, however, reduce the economic viability to do so. This country profile includes the current technologies, material flow, logistics, public policies, institutional framework, financial mechanisms, and initiatives that are being designed or have been implemented to strengthen recycling systems in the Cook Islands.
