Economic Impacts of Climate Change: India & APAC

📖 Introduction

Introduction to Climate-Induced Economic Losses

Climate change is emerging as a significant threat to global economic stability, driving substantial losses across various sectors. These losses manifest through direct impacts like natural disasters and indirect effects such as reduced productivity and increased operational costs. Understanding these drivers is crucial for formulating effective mitigation and adaptation strategies.

Key Concept: Economic Losses refer to the financial costs incurred due to climate change impacts, affecting GDP, infrastructure, human capital, and natural resources.

Sea Level Rise: A Growing Coastal Threat

One of the most immediate and impactful drivers of economic losses is sea level rise. This phenomenon threatens densely populated coastal areas, leading to increased flooding, displacement, and damage to critical infrastructure.

Projected Impact (by 2070): Approximately 300 million people are estimated to be at risk of severe coastal flooding.
Estimated Annual Damages: The global economic cost could reach USD 3 trillion annually due to sea level rise.

UPSC Insight: Questions on coastal vulnerability, displacement, and infrastructure resilience often feature in GS Paper I (Geography) and GS Paper III (Disaster Management).

Declining Labour Productivity

Rising temperatures directly impact human health and the ability to perform physical and cognitive tasks, leading to a significant decline in labour productivity. This effect is particularly pronounced in sectors reliant on outdoor work, such as agriculture and construction.

Asia-Pacific (APAC) Region: Faces an estimated 4.9% loss in GDP due due to reduced labour productivity.
India's Vulnerability: Projections indicate India's GDP loss could be as high as 11.6%, highlighting its extreme susceptibility.

Increased Cooling Demand and Energy Costs

As global temperatures rise, the demand for cooling systems in residential, commercial, and industrial sectors escalates. This surge in cooling demand translates into higher energy consumption and increased operational costs, negatively impacting regional economies.

Regional GDP Impact: Rising temperatures are projected to cut regional GDP by 3.3%.
India's Specific Decline: India is projected to experience a 5.1% decline in its GDP due to increased cooling demand.

Climate-Induced Disasters: Riverine Flooding

Climate change intensifies extreme weather events, making riverine flooding more frequent and severe. These events cause widespread destruction to property, infrastructure, and livelihoods, leading to substantial economic setbacks.

Global Damages (by 2070): Damages from riverine flooding could hit USD 1.3 trillion, affecting approximately 110 million people.
India's Economic Burden: India alone may suffer USD 400 billion in residential losses and USD 700 billion in commercial losses from riverine flooding.

Climate-Induced Disasters: Storms and Landslides

The increasing intensity of storms and changes in precipitation patterns contribute to more severe flooding and a higher incidence of landslides. These events devastate infrastructure, disrupt transportation, and displace communities.

Storm Intensity: More intense storms will inevitably escalate the severity and frequency of flooding.
Landslide Risk: On the sensitive India-China border, landslides may increase by 30-70% under severe warming scenarios, posing significant geopolitical and economic challenges.
