Final draft document of the national water and coastal management plan for Vavau
This is part of the "Preparation of Diagnostic Study to Inform an Integrated Coastal Management Plan for Tongatapu, Tonga" - this document represents Deliverable 3 : Coastal Characteristics and Issues Report
This vulnerability assessment provides evidence for the Government of Tonga and the people of Lifuka Island to make informed decisions about adapting to coastal erosion and sea-level rise. This project also aimed to be a blueprint for other low-lying nations considering adaptation options.
The objectives of this study were as follows:
1. Resurvey and delineation of the sand resource of eight beaches on Tongatapu
2. Evaluation of the extent of recent coastal changes on Tongatapu including changes effected by cyclones and other natural events, beach sand extraction, and interaction between the two.
3. Investigation of the rate of sand production and implications for the sustainability of beach mining.
This report is seen as a vehicle for catalyzing common knowledge and understanding among government, donors, NGOs, and communities on rainwater harvesting in the outer island regions of Tonga.
This report from 1992 (one of a series of reports from the Tonga Water Supply Master Plan Study) presents the findings of a recent water resources study of the islands in the Kingdom of Tonga. It summarises previous work, documents recent and current investigations and recommends further investigations to gain a better understanding of the water resources. It also outlines details of a proposed national monitoring and protection programme and makes recommendations about legislation for water resource management and protection.
The Pacific Climate Change Science Program (PCCSP) was developed to assist decision makers and planners in 14 Pacific island countries and East Timor to understand better how their climate and oceans have changed and how they may change in the future.
This dataset hosts all resources that were developed through the collaboration between Tonga and PCCSP regarding changes in Tonga's climate
