What is the scientific basis of SCIMAP?
SCIMAP is based on the identification of locations of critical source areas (Heathwaite et al. 2005). within the landscape. These locations are based on the areas that are most likely to have a source of…
How SCIMAP aids the spatial targeting of diffuse pollution mitigation measures
SCIMAP aids spatial targeting by identifying the locations in the landscape that are most likely to be contributing to an observed diffuse pollution issue. SCIMAP should be used as part of a toolkit whereby a…
Basic description of the SCIMAP framework
SCIMAP is a risk-mapping framework designed to identify where in the landscape diffuse pollution is most likely to be originating. SCIMAP does not try to make quantitative predictions in real world units (e.g. mg l-1)…
Diffuse Pollution, the Water Framework Directive and SCIMAP – an Environment Agency View
Linda Pope, Environment Agency The Water Framework Directive requires the Environment Agency assesses the ecological status of all waterbodies, determine the pressures which are causing waterbodies to not achieve good ecological status and put in…
SCIMAP Poster from LuWQ Conference
SCIMAP was presented at the Land Use and Water Quality conference in The Hague. You can download the pdf of the poster here.
SCIMAP in Under Seven Minutes
This video gives an overview of the SCIMAP approach to diffuse pollution risk mapping in under seven minutes. For a fuller, more detailed video, please see this video. There are also a wide range of…
Economic of Spatial Targeting
https://vimeo.com/63326111/ Ashar Aftab, Durham University 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…
Integrating sediment and nutrient risk in catchments
https://vimeo.com/63326113 Magda Bieroza , Lancaster University 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…
SCIMAP: A history of the rivers trust movement and hydrological connectivity
https://vimeo.com/62857760 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…
Comparing SCIMAP critical source areas to locally identified ‘hotspots’ from catchment walkover surveys.
John M Douglass, Environment Agency. 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…
