The search for solutions to these problems will require the design and 

 accomplishment of extensive field tests, the execution of laboratory experi- 

 ments, the development and test of complex numerical models, etc. Solu- 

 tions to the many legal, social, moral, and economic problems associated 

 with increased technological capability in weather modification will have 

 to keep pace. In view of the anticipated difficulties, both technical and 

 otherwise, and recalling our earlier discussion of the problem of providing 

 adequate disaster warning, we again recommend that attention be given 

 to providing incentives for the reduction of hazards through controlled 

 use of areas susceptible to flooding by rivers and inundation by high tides 

 associated with coastal storms and hurricanes. In the long term, the most 

 effective measures of all may be preventive and protective measures for 

 reducing vulnerability.
