Project summary

Edit project overview to modify the project summary.

The East Devon Rural Diffuse Pollution Project was a one-year initiative aimed at reducing the diffuse pollution arising from rural land use, in particular the growing of maize, in the East Devon river catchments of Clyst, Axe and Otter.

The primary driver for the Catchment Based Approach is the need for the UK to meet its water quality obligations under the Water Framework Directive.

This is an approach to avoid detrimental damage to our drinking and bathing water supplies, by stopping pollutants entering watercourses. This project supports farmers who are based upstream of key water supplies, providing them with advice to manage their farms and businesses with clean water, and avoid negative environmental impacts.

The project aims to identify and address potential sources of pollution on farmland, in order to protect water quality and wildlife habitats. The project is helping farmers reduce the amount of pesticides and fertiliser they use on their fields, constructing riverside fences, better drainage to prevent run-off into adjacent streams, soil management strategies, and habitat enhancement.

Initial visits by contractors to the farms in the catchment focused on analysing soil maps and discussing the farmers' plan for field management following harvest season.

Monitoring surveys and results

This case study hasn’t got any Monitoring survey and results, you can add some by editing the project overview.

Lessons learnt

Edit project overview to modify the lessons learnt.

Timing of the project - advice would have been more beneficial if delivered during 2015 earlier in the season. Also, the length of the project limits the scope of work which can be carried out.
