| Zusammenfassung |
| The economic evaluation of drought impacts is essential in order to define
efficient and sustainable management and mitigation strategies. The aim of
this study is to evaluate the economic impacts of a drought event on the
agricultural sector and measure how they are transmitted from primary
production to industrial output and related employment. We fit econometric
models to determine the magnitude of the economic loss attributable to water
storage. The direct impacts of drought on agricultural productivity are
measured through a direct attribution model. Indirect impacts on agricultural
employment and the agri-food industry are evaluated through a nested indirect
attribution model. The transmission of water scarcity effects from
agricultural production to macroeconomic variables is measured through
chained elasticities. The models allow for differentiating the impacts
deriving from water scarcity from other sources of economic losses. Results
show that the importance of drought impacts are less relevant at the
macroeconomic level, but are more significant for those activities directly
dependent on water abstractions and precipitation. From a management
perspective, implications of these findings are important to develop
effective mitigation strategies to reduce drought risk exposure. |
