Presentation Transcript

Slide1: 

Dougal McNeill Lead Catchment Officer Anglia – North England Catchment Sensitive Farming Delivery Initiative (ECSFDI)

Slide2: 

Integrated Catchment Management Industrial Transport Agriculture Mining Public supply Water Catchment Sensitive Farming

Diffuse water pollution and agriculture: 

Diffuse water pollution and agriculture Pollutants linked to the agricultural industry Nutrients – nitrates/phosphates Sediments – soil loss and erosion Pesticides - drinking water Pathogens – bathing water Flooding of roads and property Water abstraction

The ‘catchment’ model: 

The ‘catchment’ model

Water Framework Directive: 

Water Framework Directive EC directive which aims to create better waters – aquifers, lakes, rivers, estuaries and the sea – by 2015 EA have characterised river basins and impacts from all industries and users (2005) Commitment to develop Programme of Measures (2008) www .environment-agency.gov.uk.wfd www .defra.gov.uk/environment/water/wfd www .magic.gov.uk

Defra’s policy position?: 

Defra’s policy position? Believe catchment approach will underpin delivery of WFD, improve water quality – leading to biodiversity improvements Voluntary action by farmer’s within a supportive approach by government can deliver positive change Catchment advisers are key to delivering this agenda – hence CSFO

England CSFDI programme : 

England CSFDI programme Launched 19 December 05 A two-year NE/EA project Focus is farm level advice and engagement Sponsor is Defra water quality division Budget is £23.75m over 2006-2008 £9.5m in each year for ‘advice’ £5m in year 2 for a capital grant scheme

Slide10: 

The Wensum Catchment Partnership Helping Farmers Manage their Soils and Protect the River Wensum

Slide12: 

So why was the Wensum chosen as a priority Catchment for csf? ‘In 1990 about 50% of the channel length of the Wensum was covered by fine silt’ - Boar et al 1994 – NRA report. - ‘ The substrate of the channel was found to be predominantly silty, with few clean gravel stretches present, except for immediately downstream of mills.’ – Grieve et al – EN report 2003 - an article by John Wilson (2005), in the anglers’ magazine ‘Improve your Coarse Fishing’, describes the fish population of the Wensum as a ‘reverse pyramid’, with “no dace, roach or chub of any size at the bottom and middle, just big fish that the cormorants can’t eat at the top”.

Slide17: 

Incidence of autumn rainfall

Slide18: 

Since the 1930’s, 20% of the water meadow bordering the Wensum has been ploughed

Slide20: 

Source: AN INVESTIGATION INTO FISH POPULATIONS ON THE RIVER WENSUM - Kevin Roche EA

Slide21: 

EN Fluvial Audit Confirmed that silt ingress from arable fields is a major contributor to declining water quality. Not specific about sources of silt. <8% of total from bank or bed erosion.

Slide22: 

So we know that the causes of declining water quality and loss of fisheries appears to be silt ingress into the river. The source of this is not clear but national figures point to the fact that at least half of it is agricultural. 800 farmers in catchment so we need to know where to Concentrate our efforts. PSYCHIC

Slide23: 

This gives us areas where there is a risk of erosion but not areas where it is known to happen.

Slide24: 

Local data
