Project Completed

Tonga is highly vulnerable to climate change impacts, including increases in temperature and precipitation, more intense tropical cyclones, and rising sea levels. Extreme events such as Tropical Cyclones Ian in 2014, Gita in 2018, and Harold in 2020, have caused devastating flooding, destruction of physical assets, and substantial economic losses, underscoring the need for immediate and comprehensive climate action. 

To overcome these challenges, this project will drive a transformational shift in coastal adaptation in Tonga, empowering local stakeholders and communities to build a resilient and sustainable future. It will achieve this by establishing a national multi-sectoral platform to integrate climate risk information into local development planning; strengthening local capacities to collect and manage data for coastal adaptation planning; and constructing over four kilometres of sea defences in vulnerable coastal areas. Additionally, the project will address issues such as land-use planning and voluntary retreat to enhance Tonga’s long-term resilience.

An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Groups  of people who are adversely affected by climate change or the response to it

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

A tax advantage is an economic benefit applied to certain accounts or investments that are, by law, tax-reduced, tax-deferred, or tax-free. This can apply to investments in areas such as green energy projects or the agricultural sector, where tax advantages can help manage financial risks.

A loan is a policy instrument where funds are provided to a borrower with the expectation of repaying the principal plus interest.

Direct investments by the governments using public funds. This can be to support climate initiatives or integrate climate into other projects.

Compulsory, required payments to the government that are levied more-or-less in proportion to the services provided. Fees and charges range from entrance fees to national parks, charges on land-based sewage discharge.

Financial support to help individuals manage the effects of unexpected events, securing their livelihoods and increasing the resilience of people and businesses to the changing climate. It’s especially vital in developing regions where everyday risks, climate-related weather extremes, or crop failures can push people into poverty. Without insurance, people may have to resort to selling assets or cutting consumption to cope with losses.

Zoning and spatial planning are both methods for guiding the distribution of people and activities in a space, and are regulatory restriction.

The processes through which enterprises can identify, prevent, mitigate and account for how they address their actual and potential adverse impacts. Due diligence is the idea that reasonable precautions should be taken to avoid causing harm to people, the environment, or society. It also involves identifying and mitigating risks before they occur.

An integrated system of hazard monitoring, forecasting and prediction, that enables individuals, communities, governments, businesses and others to take timely action to reduce disaster risks in advance of hazardous events.

Financial actors and resources that are primarily directed towards climate change mitigation, adaptation and compensation.

Dedicated pool of financial resources for climate-related projects.

Actions and measures to adapt and increase resilience of societies and the economy to climate change.

Actions or measures to adapt freshwater, coastal and marine systems to climate change.

Hot temperature extremes are daily maximum temperatures  that were exceeded on average once in a decade or once in 50 years, and includes heatwaves.

The release of heat-trapping gases, primarily from human activities such as burning fossil fuels, agriculture and industry.

Risks to the ecosystem health of the marine environment, including ocean warming, ocean acidification, and ocean deoxygenation, harming biodiversity, species health, ecosystem services, and coastal community livelihoods.

Extreme weather refers to events where a weather variable exceeds (or falls below) a threshold. Meaning it is significantly different from the average or usual weather pattern.

Climate change can have a range of impacts on technological system. Extreme weather events can cause infrastructure failures like power outages or damage to roads and bridges, as well as the impacts from waste following natural disasters. Human activities also cause technological impacts, such as the risks posed by oil spillage and leaks.

Climate change impacts our society by disrupting the natural, economic and social systems we depend on. Physical hazards and underlying vulnerabilities can lead to increased resource competition for food and water, which can heighten the risk of conflict.

Slow onset events evolve gradually from incremental changes over many years or from increased frequency or intensity of recurring events. As defined in the Cancun Adaptation Framework (2010), slow onset events include risks and impacts from rising temperatures, desertification, biodiversity loss, land and forest degradation, glacial retreat, ocean acidification, sea level rise, and salinization.

Heavy precipitation refers to any form of weather where substances fall from the sky, including rain, snow, sleet, or hail.

Geohazards are adverse geological phenomenon's that are capable of causing widespread damage or loss to property, life and the environment, such as earthquakes, volcano eruptions and tsunamis.
