Responsible Use of Rivers Neil Edwards AquaInform Ltd 29th April 2021 Is there such a thing as responsible use of rivers?

With a reputable licensing system, what can possibly go Agri/food – market develops to favour more water intensive wrong…? products Would be users with higher economic value purposes … change eg appear Technology/techniques evolve to be more water efficient if all available rights have been issued then barrier to their market entry What was reasonable need when granted may no longer be reasonable for the purpose role for markets/trading to supplement or replace existing water resource allocation? Production/demand tails off but leaks/losses/inefficiencies develop Climate May not be cost efficient for user to fix leaks if cost of fixing > Timing, frequency, duration and intensity of rainfall events cost of water eg long period until leak fix project payback changing differently in different areas affecting water supply and storage Views on environment needs change Changing snow occurrence and snow melt timing Higher allocation to environment now thought desirable or become legally required What was once appropriate allocation of water More licencing might have been issued than is now thought resource (and implied use of rivers) may not continue consistent with desired environment protection to be as things change Could imply occurrence of environmental damage (in fully licenced scenario) if nothing is done on licensing/restricting actual use Growth in demand from existing users PWS- Population growth and change in affluence leads to demand outstripping improvements in household water use efficiency 11 ‘Jaws of Death’ Speech 2019 James Bevan (EA Chief Exec, March Assumptions for power/energy based on DECC 2011 (pre net zero/hydrogen …!) 2019) ‘Abstractors should not assume they can Action is needed to avoid demand for water always meet future growth using volumes exceeding supply in the next few decades of water held on their licences but as a result of … historically unused’ Climate change Context indicates because of EA view of environmental pressures & WFD no deterioration Population growth interpretation Environmental ambition Not all required reductions are currently quantified EA National Framework for Water Acknowledges uncertainty in projecting Resources (March 2020) non-PWS future water demand Defines Regional Planning including Creating challenges and opportunity in ‘alignment’ between regions regional planning EA assess there is enough water for each ?What is a ‘valid’
