The major question that this paper addresses is: What are the immediate
cost of land degradation for a nation? The objective of the analysis is
to develop suitable measures to explain the national costs of land degradation.
This paper further illustrates a spectrum of approaches to estimate land
degradation-induced onsite and offsite environmental effects in Sri Lanka.
The main onsite effect is the loss of soil productivity. The loss of productivity
of downstream irrigated agriculture and hydropower generation, flushing
cost of downstream reservoirs, operation and maintenance cost of highways
network in the upland, are among the common costs of offsite effects.
The study further suggests possible macro and complementary micro policy
to minimize land degradation-induced onsite and offsite environmental
costs in Sri Lanka.
