“…Another well-known example of SD application outside the business environment is the worldwide bestseller The Limits to Growth [4], in which a team of researchers studied what could happen to the global population and to the environment if development is sustained by uncontrolled use of resources. SD modelling is also widely used for analysis of natural and industrial ecosystems [5][6][7][8][9][10][11]. In ecology, SD helped to derive the fundamental rule for regulation of consecutive successional stages [12] and an innovative method to control eutrophication [13,14].…”

“…The original model on the Ventana website simulates the populations of rabbits (Figure 3), but similar principles apply to a wide range of other organisms. The learners are encouraged to adapt the population model in that respect, and a number of references are suggested where similar models have been used for algae, protozoa, cyanobacteria and diatoms [8,13,14,22,23] and zooplankton and fish [24]. Furthermore, it is emphasised that with certain modifications this modelling approach could be applied to human populations, and the learners are invited to introduce the processes of emigration and immigration, and to adapt the modified model to describe the processes relevant to the population of Ebbsfleet Garden City (Figure 4).…”

Systems Thinking and adequate modelling skills related to System Dynamics (SD) are essential for sustainable functioning of human society. The process of learning these skills can be considerably facilitated through hands-on experience with modern interactive tools in a play-like activity. Here we present a concise hands-on course on SD Modelling and Systems Thinking, give a brief description of its teaching materials (available online for free download), and discuss its potential developments, overall relevance and further implications. The course contains a session on 'Systems Thinking', and two hands-on sessions aiming to provide basic and more advanced modelling skills. Central to the latter are the examples of structural modifications for the Ebbsfleet Garden City water management model. The model represents complex processes associated with a multitude of interconnected social, technical and environmental issues. This publication provides both an important update of this model incorporating a dimensional analysis and the handson teaching support designed to aid knowledge transfer. It is envisaged that, with modifications, this freely downloadable course could be of use for modules related to a wide range of fundamental and applied disciplines, including e.g., Ecology, Geography, Engineering, Social and Environmental Sciences. It is expected that University students and other users will not only benefit from enhancing their understanding of the complexity of the specific problems considered by the examples used, but will also gain valuable basic system modelling skills through 'learning by doing'. The teaching materials presented here may be particularly useful for environmental projects involving participatory approaches.

Abstract:A study of Rostherne Mere (Cheshire, UK) was undertaken to reveal relationships among various ecosystem components and assess the progress in lake recovery following sewage diversion. An intensive monitoring programme included measurements of dissolved oxygen, T, pH, electric conductivity, K, Mg, Ca, Si, N and P species, Secchi depth, suspended solids, chlorophyll-a, phyto-and zooplankton counts. Recorded changes and the results of correlation analysis broadly confirmed to the classic limnoecological theory and allowed detailed interpretation of the dynamics observed. The Si level was used to estimate the amount of diatom detritus produced in spring. Chemical profiles were used to estimate the amount of nutrients accumulated in the hypolimnion during the stratified period. These estimates were compared with simulations made using the model of exponential decay, which showed a good performance in the case of Si but considerable underestimation in the case of P. The differences between the values simulated by the model and estimates based on field observations resulted from the additional P release from the sediments. This release could have been stimulated by a combination of factors, including the development of anoxic layers on the sediment-water interface and Si-induced desorption from Fe, Al and Mn oxides. Internal P loading during the stratified period was thus estimated at about 4-9 g/m 2 , suggesting that rapid changes in the lake's trophic status are at present unlikely. Certain aspects of this work (including interpretation of interrelationships between ecosystem components, estimation of the decomposition constant, analysis of factors controlling nutrient accumulation in the hypolimnion, and a low-cost method to estimate internal P release) may be useful for studies of other aquatic systems and have, therefore, general limnological applicability.
