This interdisciplinary research combines recent advances in science and innovative economic incentives to develop forward-looking and practically implementable spatially targeted policies to regulate agricultural externalities. The substantial efficiency savings from spatial targeting offers a rare ‘win-win-win’ for regulators, farm businesses and the environment. Present regulation does not discriminate at a [...]

Lancaster University is developing further and integrating the risks from fine sediment, phosphorus and nitrogen losses from catchments using the SCIMAP approach pioneered by Durham and Lancaster Universities. We aim to develop a risk-based catchment screening tool to locate the nutrient pollution hot-spots within the catchments: locations that produce [...]
Alistair Maltby, Director North, The Rivers Trust
The earliest principles of the rivers trust movement were based on managing catchments as watersheds, and the twelve principles of the ecosystems approach. In the agricultural dominated landscapes of our rural rivers, this has lead to delivery of work often summarised in an offhand way as; “look [...]

A good SCIMAP-sediment model will identify probable critical source areas of fine sediment within a catchment at a field scale. It does this by estimating relative erodability of soils and estimating hydrological connectivity across a high resolution DEM. However, land management practice often varies at a scale finer than [...]

If we can determine which pressures are exerting negative impacts on the water quality in our aquatic ecosystems and identify their sources in a catchment, then we can develop a programme of tailored and targeted interventions to remove these sources and disconnect their pollution pathways.
For many point sources [...]
David Higgins, Yorkshire Dales Rivers Trust
The Yorkshire Dales Rivers Trust has been using SCIMAP to target investigations for at least five years. Many of the restoration works carried out have been directed by the model. Wetlands, gill planting and wood pasture have been implemented based on the outputs in combination with walkover surveys. The Ripon Mulit-Objective Project [...]

11:00 [Cancelled] Using SCIMAP with other Water Quality models for Water Framework Directive investigations.
The first SCIMAP user group meeting will take place on the 26 October 2012 in London. The aim of this meeting is to bring together the current users of SCIMAP from the Environment Agency, Natural England, the River Trusts, Wildlife Trusts and others to discuss how they have used the tools, to learn from each [...]
