Example: <Insert site name and issue> INSERT PICTURE
Human Activity <insert example of HA> <Insert example> is an Human Activity (HA). The term HA refers to human intervention in the function and structure of natural systems. INSERT PICTURE
Forcing <insert example> Physical pressure is a force per unit area. `Nutrient loading' implies an increase in nutrients over what was a `normal' level. INSERT PICTURE
System state <insert example> where `State' or `Status' represent the situation at a specific time. INSERT PICTURE
Response <insert example> A forced rate of change in the ecosystem. Eutrophication would be seen as part of this. INSERT PICTURE
Impact <insert example> SPICOSA takes `Impact' as the end-result in a cause-&-effect chain, with direct consequences for ecosystem users, such as those involving harm to a fishery from deep-water anoxia. INSERT PICTURE
Policy change <insert example> SPICOSA does not pre-suppose what type of Policy decision should be made. It provides scenarios to show policy makers what will occur, given certain management choices. INSERT PICTURE

Models • A tool to represent the real world in a way that can be used to understand how the system works and make forecasts. • Can be used to give an idea of the effect of different management options. • Models may be conceptual, mathematical or numerical.
Types of models • Conceptual Model- a pictorial or verbal description of selected features of a system, usually made inductively and capable of qualitative predictions by deduction • Mathematical Model- a formal mathematical representation of selected features of a system • Numerical Model- a tool based on a mathematical model; a transformation machine that takes data from an input and converts it to a prognostic or diagnostic output; often implemented as, or using, a computer program.
Data requirements • What metric will you use for each variable? • Clear link with your issue of interest. • Time series • Common collection method throughout • Apples with apples • Same time steps • Modelled data FAO North Sea fertilizer use data http://faostat.fao.org

Water levels in the Bay • Influence: • Rainfall • Evaporation - 0.003 m-3/day. • Water loss from the weirs in the barrage which takes 100000m3 water/day when the bay level is greater than 500 000 000 m3.
Pollution inputs • Industry – 200 businesses in the area abstract water from the bay as coolant; these return with heavy metals at a rate of 0.0001 Kg/day. • Pollution amount is reduced by outflow from the weir into the Bristol Channel at concentration level. • Amount not reduced by evaporation.
Economics • The port authority is paid £0.15per factory/dayabstracting coolant from the bay. • Tourists visit the Bay and spend an average of £20 a day. • Tourists will only come if the concentration of heavy metals is below 3 x 10-7 kgm-3 where signs will be posted on the beaches warning of pollution. • Money is available to develop a treatment plant to remove heavy metals at a cost of £0.01per m3 of water.
