|Abstract:||In the Hawaiian Islands, planners and public officials have decided recently to raise the permissible level of urban development in central Oahu. The decision is opposed by many on the grounds that it threatens
agricultural land as well as the sustainability of aquifers. A two-part procedure is presented for exploring
the impact of such development and designing urban-expansion patterns that minimize them. First, a water-balance simulation model is used to calculate groundwater recharge as it varies with land use and location within the area. The difference between recharge and withdrawal is computed, and any changes
are then estimated for different land uses. Second, this information is incorporated into multiobjective programming models with objectives related to agricultural land retention, groundwater balance, and
residential population growth. The models generate alternative land-use expansion plans and show the tradeoffs among the objectives. The consideration of slightly suboptimal (dominated) solutions allows
a significant expansion in the range of such alternatives. The results suggest that if future agricultural development does not occur on currently nonagricultural land, then both agricultural land and groundwater
sustainability will suffer significant adverse effects under the new population limits.
