and the optimal production values for each retailer can be obtained.
Secondly, we demonstrate that the first-stage objective function for
each retailer is concave in the amount of leased farm land. Finally, the
paper concludes that equilibrium can be found for both retailers in this
production planning problem.

We investigate two conjunctive surface and groundwater usage
management systems with two identical users in a dynamic game-
theoretic structure over a planning horizon of two periods. Under the
centralized management system, both users are allowed to use
surface water from their own reservoirs as well as to use groundwater
from a common aquifer with the supervision of a social planner. Under
the decentralized management system, each user is allowed to use
surface and groundwater, respectively, from his reservoir and from
the common aquifer making usage decisions individually in a non-
cooperative fashion. Earlier works on groundwater management and
on conjunctive water usage management motivate our work to
consider a model which integrates the conjunctive water usage in a
more comprehensive and realistic setting permitting the gaming
behavior between users. Analytical results regarding the optimal
water usage quantities are obtained under both centralized and
decentralized management systems.
