International treaties and national policies seek to enhance global efforts to mitigate and adapt to climate change. While it is important to continue to strive to reduce greenhouse gas emissions, mitigation alone is not enough and will not be felt before the second half of the century. Global warming is already underway and adaptation strategies are now a matter of urgency, especially for the most vulnerable poor countries, which are even now being disproportionately affected.

Mangrove systems occur extensively on low gradient tropical shorelines, where sedimentation enables resilience during sea-level rise (SLR). Within mangroves, inundation frequencies across the intertidal slope cause zonation of different species with elevation. This tight sea-level control of the seaward margin and zones within mangroves has been demonstrated by precise EDM survey. Hence species zones in mangroves are definitive indicators of sea-level position, and pollen
The Tonga State of the Environment 2018 report has been developed to answer three key questions related
to the environment of Tonga, and is based on seven thematic areas:
• What is the current condition of the Tongan environment?
• What are the risks the Tongan environment faces and what measures have been put forward to minimise them? This could provide lessons for Tonga.
• Where is the environment of Tonga headed based on the assessed thematic areas?
