Good practices in managing archaeological remains

Lisbon is a city with enormous archaeological wealth. Every year hundreds of archaeological interventions take place resulting in an enormous volume of archaeological remains. It is not sustainable to keep everything, and it is necessary to implement a strategy that allows a selection to be made and guarantee the generational transferability of this heritage. How are others in Europe responding to this challenge? What strategy did they adopt? What resources have you made available for this purpose? This is an expensive and complex task that requires good practices and sometimes sophisticated human and logistical resources.
