Agriculture Bill — House of Lords, 2020-07-07
Topic: Environment
David Chidgey (Liberal Democrats, Centre to centre-left): I will speak to Amendment 83 to Clause 1, in particular the work that my noble friend Lord Greaves mentioned. I will highlight the issue of catchment areas and draw attention to the fact that, while they create great difficulty in some areas of the country, they also do so in some of the most favoured areas, if I may put it that way The catchment areas in question are a series of spring-fed chalk streams and their seasonal winterbournes, which define the landscape around Winchester in north Hampshire. Many people know that they are famed for their world-class fly fishing for the most favoured in the rivers Test and Itchen, and for the watercress industry around Alresford. The unique landscape is a product of human as well as natural history, providing drinking water for Southampton and, at one time, pure water for banknote watermarking at the De La Rue works near Basingstoke In the last 50 years—certainly while I have lived in the area—more than half of all wildlife species have declined across the UK, never more so than in Hampshire’s winterbourne and watercress landscape, including its conservation areas, sites of special scientific interest and areas of outstanding natural beauty. Historically, efforts to protect rivers and their ecology focused on the channel and possibly the immediate floodplain. There now needs to be an increasing awareness that a river system is inherently linked to and affected by its wider catchment The water framework directive recognises this and requires a holistic view of the needs of the freshwater environment. It identified the pressures affecting Hampshire’s seven headwater chalk streams and set targets for the improvement of the chemical and ecological status of each. It also required stakeholders to be involved in local decision-making and delivery. Clearly, the quality of the water in these headwater chalk streams is critical, contributing as the streams do to the Test and Itchen river systems and the groundwater resource they share It therefore has to be a cause of considerable concern that recent surveys have shown that all the streams are at risk from excessive levels of nutrients, sediment and pesticides, the worst case being the River Alre, which is literally on my doorstep. The lake behind a weir, built in the 16th century to control the river waters before entering Alresford’s watercress beds, is heavily polluted with nitrates and phosphates, largely due to agricultural run-off. The Environment Agency is understood to have recently tested the water in the River Alre above the lake and found it below standard. An industrial-scale salad-washing plant is nearby and is licensed to use the river water to wash all pesticides and other chemicals from salads imported from Europe and elsewhere for distribution across the UK Apparently, the Environment Agency is required to negotiate with polluters over infringements rather than close them, with predictable results. The Agriculture Bill should present an opportunity to strengthen this rather toothless organisation to tackle this extremely harmful abuse. To give just one example, Salmon & Trout Conservation considers the presence of these pesticides responsible for the marked decline in Gammarus freshwater shrimp, the foodstuff of the trout of the river I draw your Lordships’ attention to the UK Progress on Reducing Nitrate Pollution report from the other place. Have the Government taken action to take up and recognise the recommendations made by the committee that produced the report? They will be essential to tackle this hugely damaging problem of nitrates in our watercourses, water tables and water catchments.
