The Demonstration Test Catchments (DTC) project is a joint Defra, Environment Agency (EA) and Welsh Assembly Government initiative working in three river catchments – the Wensum in Norfolk plus the Eden (Cumbria) and Avon (Hampshire).

The overall objective of the project is to provide evidence to test the hypothesis that it is possible to cost effectively reduce the impact of agricultural diffuse water pollution on ecological function while maintaining food security through the implementation of multiple on-farm measures across whole river catchments using local expertise to solve local problems.

Forthcoming events

  • 26 May 15: Agri-Tech East and Anglian Water workshop: Balancing water supply and demand (near Duxford 12:30 - 16:00) This event is aimed at farmers and landowners and will offer a practical insight into industry decision making, the challenges that industry and agriculture both face in terms of water availability and investment options to meet the growing demand for water in our region. For more information and to register [click here].
  • 04 June 15: Agri-tech East visit to Salle Agri-tech East has a farm site visit to Salle, Norfolk to showcase some of the Wensum Demonstration Test Catchment's collaboration with Manor Farm, explore a variety of installed measures and cropping practices. To find out more [click here].
 

What's in the news?

Pensthorpe Wild About the Wensum event 2015
  • 22 April 15: Wild About the Wensum The annual family day at Pensthorpe nature reserve was the biggest yet, with many wildlife and conservation organisations present and lots of families, Brownie and Cub Scout groups attending. Our stand proved popular, with educational activities for all ages including water testing, our ever-popular catchment model and a new quiz.
  • 31 March 15: Second Phase of DTC gets underway After a long process of procurement the new contracts for the monitoring component of DTC are finally being put in place. Defra has taken the opportunity to expand the brief and also attempt to bring together different strands of work, emphasising the multi- and trans-disciplinary nature of the work and the issues that it needs to address. See the latest newsletter from the DTC programme for the full story and further updates from all the catchments [click here].
CATSCI Workshop March 2015
  • 20 March 15: CATchment SCIences (CATSCI) workshop account UEA post-graduate student Nick Garrard recently attended a NERC funded postgraduate and professional skills development CATchment SCIences (CATSCI) workshop that included several farm visits (picture right from Phil Haygarth) and concluded with a ‘Dragon’s Den’ style presentation.

  • 20 March 15: Nitrous oxide emission from field drains at Salle UEA Researcher Zanist Hama-Aziz has been examining nitrous oxide (N2O) emission from field drains at Salle. Nitrous oxide is a potent greenhouse gas that persists in the atmosphere and has 298 times more global warming potential than CO2. Emissions of N2O arise both directly from fertilized soils and indirectly from drainage streams, groundwater, rivers and estuaries. N2O is highly soluble in water, thus a significant amount of N2O may be discharged with drain water and released to the atmosphere. To read about the results of Zanist’s work [click here].
  • 18 March 15: Congratulations to Richard Cooper & Co. for three notable research publications Richard Cooper and other research collaborators have recently had three papers published relating to work on the Wensum DTC. Collectively, the developments presented in these three papers significantly advance sediment fingerprinting research by enabling organic and inorganic fluvial sediment fractions to be quantitatively apportioned at both low- and high-temporal resolution within realistic levels of uncertainty, thereby enhancing our understanding of sediment dynamics under a range of instream hydrological conditions.

  • 09 Mar 15: Agritech Water Cluster workshop, Wisbech Agri-Tech East’s ‘Water for Agriculture‘ Special Interest Group, in partnership with the Agritech Water Cluster (based at the University of East Anglia) and Anglian Water, who have an interest in non-domestic water supply and demand, presented a workshop to explore future water needs in food production, processing and packing. Attendees at the workshop all used water varied ways from agricultural production, food processing, industry experts, innovative and agri-tech driven companies as well as tourism. The event started with brief introductions from the organisers: Agri-Tech East, Anglian Water and the Agritech Water Cluster outlining the plan for the day. Inder Poonaji, Head of Sustainability at Nestlé, gave an inspiring introductory talk on Nestlé’s approach to water efficiency and their commitments to reducing their water usage by 50% in 2020.
