2014 - Ghana - Economic Impact of Climate Change
Climate change scenarios for many Sub-Saharan African countries including Ghana
indicate that temperatures will increase while rainfall will either increase or decrease. The
potential impact of climate change on economic systems is well-known. However, little has been
done to assess its economic impact on road infrastructure. This work assesses the economic
impact of climate change on road infrastructure using the stressor-response methodology. Our
analysis indicates that it will cumulatively (2020-2100) cost Ghana US$473 million to maintain
and repair damages caused to existing roads as a result of climate change (no adapt scenario).
However, if the country adapts the designing and construction of new road infrastructure
expected to occur over the asset’s lifespan (adapt scenario), the total cumulative cost will increase
to US$678.47 million. The paper also provides decadal and average annual costs up to the year
2100 for the ten regions through the potential impacts of 54 distinct potential climate scenarios.
