18. Policy Implications 23 Commitment and investment are necessary for successful implementation of the dissemination network Better-informed and timely decision can be made through the use of this network Main problem: setting up an environment for information sharing, i.e., policy principles need to be set up Other problems such as pricing of data, copyrights, security concerns need to be clarified
