Exploring the Economics of Climate Adaptation

Today, most agree that decision-makers at every level should consider the effects of climate change on local levels, evaluate potential strategies, and implement climate adaptation projects accordingly. To approach climate threats in a low-risk and cost-effective way, though, there must be a well-defined process in place. The Economics of Climate Adaptation (ECA) is a monitored system that offers a framework to provide decision-makers with the information they need to evaluate climate risks and develop cost-effective adaptation plans. It allows strategic development systematically – ensuring well-targeted investments toward climate resilience across public and private sectors. 

Below, we look closer at how the economics of climate adaptation unfolds and how the world aims to improve climate adaptation strategies with the ECA. 

What is the Economics of Climate Adaptation (ECA)?

The Economics of Climate Adaptation (ECA) is a system that offers an innovative framework for governments and policymakers to identify and quantify climate risks to local or national communities and better develop climate adaptation strategies. The framework doesn’t just help build adaptation frameworks, though. It aims to make them as cost-effective as possible while maintaining strategic integrity to solve the most challenging climate problems we currently face.

The ECA addresses climate change by asking three questions:

1. What is the potential for climate-related damage in the coming decades in a specific city, state, or nation?
2. How much of the damage can we avoid, and which climate adaptation strategies should we utilize to do so?
3. How much investment is required to fund the strategies, what type of investment is ideal, and will the benefits outweigh the investment cost?

How does the ECA Work?

The ECA works by following a practical framework that allows a comprehensive assessment of climate risks to communities and economies while minimizing the cost of adaptation strategies. The framework follows eight key phases to provide a strategic implementation.  

1. Define a Research Area
2. Data Acquisition and Management
3. Define Scenarios
4. Model Hazards
5. Valuate Assets
6. Create Damage Functions and Risk Analysis
7. Identify and Simulate CCA Measures
8. Illustrate Results

1. Define a Research Area

• This phase defines an area of research and identifies the risks and assets involved. Relevant assets include people, locations, houses, commercial activity, etc. This step offers guidance on integrating stakeholders and decision-makers at the beginning stages. 

2. Data Acquisition and Management

• The second phase involves identifying critical data needed for the CCA assessment. It gives direction in assessing available data and helps identify which institutions to involve. Phase one directly influences data collection, database construction, and data storage processes. 

3. Define Scenarios

• Pase three outlines the steps of defining climate scenarios and their socio-economic impacts. It demonstrates how to assess a current situation and decide which scenario is relevant to a project’s goals. A CCA0-relevant time horizon is determined, teams will develop scenario-relevant information for hazards, assets, and economic scenarios.  

4. Model Hazards

• Ultimately, phase four provides guidance on creating hazard impact maps using CLIMDA. 

5. Valuate Assets

• Phase five helps evaluate the various categories of assets and how to include them in the CLIMDA framework. It also provides teams with recommendations on placing values on assets with little to no monetary value. Step five is particularly important for developing and emerging countries and economies.  

6. Create Damage Functions and Risk Analysis

• Phase six gives information and guidance on the different classes of assets and hazards to create damage functions and risk analysis. It helps gather data on past disasters in your location and provides further guidance to develop damage functions based on past occurrences. Finally, this phase includes information on implementing the risk analysis and damage functions into the CLIMDA framework. 

7. Identify and Simulate CCA Measures

• Phase seven allows teams to create a long list of CCA measures and break it down to only the most essential aspects in a shorter list using a multi-criteria selection process. It then helps you implement the list into CLIMDA and calibrate the measures for optimal results. 

8. Illustrate Results

• Phase eight supports teams in summarizing and presenting findings across the entire project. It helps define the audience and gear the results toward them directly and efficiently. 

Why do We Need the ECA Moving Forward?

According to a 2019 UN Sustainability Development Goals report, climate change is the most urgent area for action. The report suggests that if we do not take swift and effective action, many parts of the world will be uninhabitable by 2050 – potentially displacing up to 140 million people. Millions of people worldwide live in poverty, have no or low access to nutritional foods, or have little access to clean water resources. These circumstances make today a better time than ever to expand and explore additional climate change adaptation resources to improve the quality of life for everyone in the future. 

Some of the biggest hurdles in reaching sustainability and climate change goals are assessing climate risks accurately and developing adequate adaptation strategies for future resilience. With tools and frameworks like the ECA, we take a step closer to reaching those goals and improving our overall understanding of climate change and its effects on our planet and populations.  

Cost Estimates for Global Climate Adaptation 

Funding climate adaptation is a no-brainer for those aware of the threats we face on local, regional, and global scales. While more than 75% of nations dedicate money to climate adaptation strategies, a significant gap stretches the bounds of what we need to reach climate competency. 

While it’s undoubtedly true that loss of life, biodiversity, and cultural identity are nearly impossible to measure monetarily, some evaluation methods must exist to maneuver in the right direction. According to the UN, developing countries need to spend upward of $70 billion on climate adaptation strategies to prepare for future climate consequences. Experts expect that figure to reach nearly $300 billion by 2030. While the cost of adaptation may seem high now, it pales compared to what the consequences could bring. 

The Green Climate Fund, established as part of the framework of the UNFCCC, has now allocated over 40% of its funding to climate adaptation strategies while maintaining a steady increase of private investment. The Green Climate Fund provides financial sustainability using new tools to set sustainable investment criteria, climate-related disclosure principles, and climate investment risks – giving investors the peace of mind they need to make comprehensive and informed decisions. 

Economists and climate scientists estimate nearly three times more jobs result from climate adaptation strategies than fossil fuel investment. These estimates show that climate adaptation can have significant benefits beyond saving human lives, environmental health, and natural resources. 

Today, most agree that decision-makers at every level should consider the effects of climate change on local levels, evaluate potential strategies, and implement climate adaptation projects accordingly.
