Water Flows in the Economy. An Input-output Framework to Assess Water Productivity in the Castile and León Region (Spain)

摘要: Traditionally, water policy has focused on coordinating the public effort required to fuel economic growth by supplying services demanded as a result of progress in many areas economy. Under this supply-oriented paradigm, population and improvement living standards brought about development have driven demand up pressures over resources escalated. The failure acknowledge limited availability decouple from resulted dependent model that is currently threatened increasing scarcity more frequent intense droughts. Consequently, there an urgent need use sparse sustainable efficient way. This demands comprehensive assessment productivity dynamics well linkages among sectors order calculate actual costs eventual reallocations environment establish priorities design strategic actions such river basin or drought management plans. However, available studies only offer static analyses are insufficient attain dual objective reverting current trends without impairing growth. paper develops methodology based Hypothetical Extraction Method estimate inter-temporal indirect (i.e., including intersectoral linkages) values. method applied Spanish region Castile Leon for period 2000-2006. intensive low found agriculture confirms intuition sector play fundamental role any saving policy. relevant between rest economy, which acts consumer irrigation, may complicate finding Pareto allocation.
