Impact on Infrastructure

Increased Intensity and Frequency of Cyclones

Vulnerabilities:

• Infrastructure Damage: Strong winds and heavy rains associated with cyclones can cause severe damage to buildings, roads, bridges, and utility systems.
• Disruptions to Services: Cyclones can disrupt essential services like electricity, water supply, and healthcare, which can take considerable time and resources to restore.

Consequences:

• Economic Impact: The costs of repairs and the economic downtime during and after cyclones can be substantial, affecting local businesses and the overall economy.
• Loss of Life and Displacement: High winds and flooding pose direct threats to life and can displace communities, leading to short-term and long-term humanitarian challenges.

Rising Sea Levels

Vulnerabilities:

• Coastal Erosion: Rising sea levels contribute to coastal erosion, threatening coastal infrastructure, including roads, housing, and tourist facilities.
• Saltwater Intrusion: The encroachment of saltwater into freshwater systems can compromise water supplies and negatively affect agricultural lands.

Consequences:

• Loss of Property and Habitat: As sea levels rise, coastal areas can become uninhabitable, leading to loss of property and important natural habitats.
• Adaptation Costs: Significant investment may be required to build sea walls, elevate buildings, and relocate infrastructure and communities.

Increased Stress from Extreme Weather Events

Vulnerabilities:

• Flooding: Intense rainfall events can overwhelm drainage systems, leading to flooding that damages infrastructure and disrupts normal life.
• Heatwaves: Increased temperatures and heatwaves can stress power grids (due to increased air conditioning use), and deteriorate road and bridge materials faster.

Consequences:

• Public Health Risks: Flooding and heatwaves pose significant health risks, including increased incidences of heat-related illnesses and waterborne diseases.
• Infrastructure Strain: Frequent and severe weather events strain existing infrastructure, necessitating more frequent maintenance and faster aging of assets.

Adaptation Strategies

Strengthening Infrastructure:

• Building Resilient Structures: Designing and constructing buildings and infrastructure that can withstand stronger storms and higher loads.
• Upgrading Drainage Systems: Enhancing drainage systems to cope with increased rainfall and prevent flooding.

Strategic Planning and Policies:

• Spatial Planning: Implementing zoning laws that restrict development in high-risk areas such as flood plains and low-lying coastal zones.
• Integrated Risk Management: Developing comprehensive disaster risk management plans that include early warning systems and emergency response strategies.

Community and Ecosystem-Based Approaches:

• Mangrove Restoration: Restoring mangroves which provide natural storm barriers and help reduce wave energy and storm surge impacts.
• Public Awareness and Preparedness: Educating the public about risks and preparedness measures to reduce vulnerabilities and enhance community resilience.

Economic Diversification:

• Supporting Diverse Economic Activities: Encouraging economic activities that are less dependent on climate-sensitive resources, reducing overall vulnerability to climate impacts.
