| description |
The world's climate is changing. It
is well recognized that technical standards and project
specifications of public infrastructure have to be adjusted,
depending on the climate. However, it is less recognized
that the public infrastructure procurement also needs to be
adjusted. This paper examines a particular case of rural
road procurement in Nepal. Severe weather conditions, such
as heavy rains and storms, are likely to interrupt civil
works and wash away unpaved or gravel roads. It is found
that heavy precipitation causes delays, but not cost
overruns. The paper also shows that budgetary efficiency and
credibility could be improved by taking climate conditions
into account. If future precipitation were anticipated by
backward-looking expectations, many large project delays
could be avoided. If the autoregressive precipitation model
were used, the vast majority of the observed delays could be eliminated. |
