Natural disasters create significant impacts in the Pacific Islands: between 1950 and 2004 more than 200 disasters resulted in ovecrm_tongar 1700 fatalities and losses of USD 6.5 billion. Given their small populations and economies, such impacts represent significant shocks to Pacific Island countries. Tonga like the other fifty-one Small Island Developing States is highly susceptible to the impacts of climate change and disaster risks. Its susceptibility is principally due to its geographical, geological and socio-economic characteristics. Climate change and natural disasters pose serious adverse impacts on the environment, the people of Tonga and their livelihoods. Scientific findings revealed that these impacts would be exacerbated by future climate change. The Government of Tonga understands these significant detrimental impacts of climate change and disaster risks to sustainable development of the country hence considered these issues as high priorities in its National Strategic Planning Framework. With support from UNDP and Australian Government Pacific Adaptation Climate Change (PACC) project in Tonga assisted to increase the resilience of the water resources management sector and to enhance adaptive capacity of villages/communities and socio-economic activities to climate change and sea level rise. The paper doesn’t describes the PACC results rather water resources impacts due to climate changes.
