Climate Change, Groundwater Salinization and Road Maintenance Costs in Coastal Bangladesh
The potentially-adverse impact of salinity on paved roads is well-established in the engineering literature. The problem seems destined to grow, as climate-related changes in sea level and riverine flows drive future increases in groundwater salinity. However, data scarcity has prevented systematic...

| description | The potentially-adverse impact of
salinity on paved roads is well-established in the
engineering literature. The problem seems destined to grow,
as climate-related changes in sea level and riverine flows
drive future increases in groundwater salinity. However,
data scarcity has prevented systematic analysis for poor
countries. This paper assesses the impact of groundwater
salinity on road maintenance expenditures in the coastal
region of Bangladesh. The assessment draws on new panel
measures of salinity from 41 stations in coastal Bangladesh,
and road maintenance expenditures, income, road network
length, and road surfaces from 20 coastal municipalities. In
a model relating maintenance expenditure for paved roads to
groundwater salinity, municipal income, and road network
length, large and significant effects are found for
salinity. The regression model is used to predict the effect
of within-sample salinity variation on road maintenance
expenditure share, holding municipal income and road length
constant at sample mean values. Increasing salinity from its
sample minimum to its sample maximum increases the predicted
road maintenance expenditure share by 252 percent. The
implied welfare impact may also be substantial, particularly
for poor households, if diversion of expenditures to road
maintenance reduces support for community sanitation,
health, and other infrastructure related programs. |
