Economic Assessment of Climate Change Linking WEAP to an Agricultural Production Model

SEI is collaborating with the University of California–Davis to link an agricultural production model based on water valuation for irrigation water, SWAP (State Wide Agricultural Production Model), with SEI’s WEAP (Water Evaluation and Planning System).

Inactive project

2007

The goal is to provide more accurate projections of agricultural water demand by incorporating socio-economic factors.

The integration of both models is performed by doing a step function approximation of water demand curves from SWAP and by relating those to the priority scheme in WEAP. In order to incorporate economical water demand curves into WEAP, a modified version of the model was created called ECONWEAP, which incorporates agricultural land decisions via a series of iterations run via an external VBA script. The model is used for an economic assessment of climate change for the entire Central Valley in California under three land changes scenarios of agricultural land based on population growth projections. The outcome of this work is a series of climate change and population projections to 2100.
