National ammonia reduction strategy evaluation system (NARSES) - AM0101

Description
The objective of the Project is to develop a national-scale model to estimate the magnitude, spatial distribution and time course of agricultural ammonia (NH3) emissions and the potential applicability of abatement measures with the associated costs. The system will integrate the national environment database established under NT 1701 (MAGPIE) for England and Wales, with data sourced by CEH for Scotland and Northern Ireland with the principles incorporated in the MARACCAS model of ammonia emissions and abatement strategies.
The extent to which we can disaggregate data on livestock numbers and manure management systems, cropping and fertilizer-N use and environmental limitations on abatement practices will be determined. The MARACCAS model calculates national ammonia emissions and cost curves for implementing abatement measures. The new model National Ammonia Reduction Strategy Evaluation System (NARSES)) structure will be configured so that it will incorporate NH3 emission factors consistent with the UK Ammonia Emissions Inventory (UKAIE), (AM0108)
The end product will be a GIS-based model that MAFF, FRCA and others can use to investigate cost-effective implementation of strategies for NH3 abatement at national and other scales, and to estimate the impact of autonomous developments on emissions of NH3.
Objective
1. Review available data on environmental factors, land cover and use, livestock husbandry, soil type and applicability of abatement measures to assess the extent to which they may be disaggregated regionally and temporally. (Module 1)

2. Develop the MARACCAS model to estimate the size, spatial distribution and time course of NH3 emissions and to produce a figure for national NH3 emissions that is consistent with the current UKAEI. Review applicability of abatement measures and their costs in order to calculate cost curves and abatement potential (Module 3)

3. Produce Schedule of likely options (policy, farm management) to ask of the Model and produce a matrix of acceptability for abatement techniques. (Module 6)

4. Build desktop Policy Model software to interface with outputs from new core model. (Module 2)

5. Build link between NH3 reduction and nitrate loss and other issues in order to assess the consequences of reducing for nitrate and other issues ofNH3 abatement. (Module 5)

6. Run scenario analyses for NH3 abatement options, and run sensitivity analyses (Module 2)

7. Select 10 abatement scenarios to be used for modelling impacts.

8. Produce training manual and organise workshop to demonstrate the model to the Steering Group.

Overall, the aim will be to deliver a robust product for use by MAFF, FRCA and other users to examine the policy options of NH3 abatement in the UK.
