Different than the Oslo agreement, this model is based on a dynamic agreement between the sides, and suggests an alternative to the "temporary" agreement in place since 1995. The model presents an institutional structure with four critical bodies to implement the principles for joint management, where two central bodies lead the process: a "Bilateral Water Commission" and a "Water Mediation Board". Principles of joint management include: economically efficient water management; socially and politically equitable (not necessarily equal) water management; ecologically sustainable water management; management that would be implemented in practice.
