Long-term Aggregates Supply: Part 2

The Managed Aggregate Supply System (MASS) is believed to provide good historical data and the current forecasting process provides regularly reviewed, and in recent years more reliable estimates of demand. However there is no existing work which links these two processes together. A graph attempts to do this by comparing past sales of land-won aggregates and the current draft forecasts. The data shows likely future shortfall which will require replenishment or replacement. The information in the graph helps to test the scope of the various elements of supply. These include recycling; secondaries; marine; imports; primary sand and gravel; and primary crushed rock. While the MASS system has served well in the past, it is now necessary to re-think forecasting techniques. A new agenda and new solutions are put forward, including education and engagement of planning committees; resource mapping; reserve evaluation methodology; AM data presentation; annual performance reports; identification of nationally strategic sites; recognition of the significance of rail-linked and wharf sites; evaluation of regional surpluses and shortfalls, including the scope for transfer; development of regional and national capacity-to-supply tools and scenario planning tools; realism about alternatives and imports; and recognition of the importance of long-term planning.
