The Objectives: Fiji’s Development Plan and Objectives 44 3. The Threats: Natural Hazards and Long-Term Climate Change 46 3.1 Fiji faces a high and increasing level of disaster risk 47 3.1.1 Past events demonstrate the high risk level in the country 47 3.1.2 Many natural hazards are expected to become more intense or more frequent 49 3.1.3 High asset risk is explained by large exposure and high vulnerability in various sectors 56 3.1.4 Despite the population’s resilience, the risk to livelihoods and well-being is high and natural hazards keep people in poverty 66 3.1.5 Managing hazards requires actions in multiple sectors to avoid unacceptable risk to development objectives 80 3.2 Climate change creates long-term threats to Fiji’s development plans 82 3.2.1 Sea-level rise will multiply coastal risks and threaten some settlements in the absence of major investment 82 3.2.2 Impacts on agriculture and food security threaten a vulnerable portion of the population 83 3.2.3 Health issues will change as a result of development and climate change 89 3.2.4 Tourism plays a critical role in Fiji’s economy and is subjected to multiple stressors 93 3 4. The Options: Five Major Intervention Areas to Adapt to Climate Change 96 4.1 There is a window of opportunity to ensure serviced land and housing in safe areas 100 4.1.1 Appropriate land-use planning is critical for safer urban development, and safe areas can be identified for future development 101 4.1.2 The residential land shortage should be addressed in a resilient and sustainable manner 104 4.1.3 Informal settlements should be upgraded, taking into account current and future risks, where security of tenure can be successfully negotiated with the landowner 104 4.2 Strengthened infrastructure will help to meet the needs of the Fiji economy and population 105 4.2.1 Large investments in flood risk management and coastal protection measures will be required 105 4.2.2 The transport sector has the largest investment needs for building the country’s resilience 107 4.2.3 Strengthening the resilience of the energy sector will require a range of critical investments 110 4.2.4 Water sector investments are needed to protect assets against natural hazards 113 4.2.5 Investments in health and education infrastructure are needed to strengthen existing assets and construct new, robust facilities 115 4.3 Support for agriculture and fisheries development should be smart for climate, the environment, and the economy, now and for the future 116 4.4 Conservation policies can protect assets and reduce adaptation costs 117 4.5 The government needs to build socioeconomic resilience, take care of the poor, and keep economic growth inclusive 118 4.5.1 Improving early warning effectiveness and preparedness will save lives and protect assets 118 4.5.2 Social protection can be further strengthened to make the population better able to cope with shocks, and insurance-based solutions can be explored 119 4.5.3 Improving the health care system is a development priority 122 4.5.4 Targeted gender interventions and specific measures to protect vulnerable populations can complement actions in different sectors 123 4 Climate Vulnerability Assessment MAKING FIJI CLIMATE RESILIENT 5. The Foundations: Evidence-Based Decision Making and Well-Managed Public Finances 124 5.1 Evidence-based decision-making for future resilience requires additional data collection and analytical work 125 5.1.1 Data collection and analytical work are the foundation for efficient action 125 5.1.2 Asset management systems could improve the efficiency of infrastructure maintenance, cut costs, and increase resilience 127 5.2 Development under climate change requires well-managed public finance and significant investment capacity 127 5.2.1 Various tools can be mobilized to manage economic shocks and contingent liabilities 128 5.2.2 Meeting infrastructure investment needs will require private sector participation and increased international financing 132 5.2.3 Climate finance could support Fiji’s adaptation and resilience efforts 133 6.
