At the individual field level, shifting cultivation is essentially a resource extraction problem akin to a pulse fishery &ndash; a short period of intensive use of the stock of soil fertility followed by a long idle period permitting regeneration. This paper describes a spatiotemporal model of resource extraction adapted to the use of forest resources by shifting cultivators. Theoretically grounded in the spatial and household modelling literature, it is a structural simulation model of household decision-making, and includes a demonstration of the conceptwith a limited data set from southern Cameroon. Use of a stated preference approach to modelling decision-making identifies individual preferences and spatial path-dependency as important sources of shortened fallows and resource degradation.</p>1 aBrown, Douglas, R  u//www.simulistics.com/publications/spatiotemporal-model-shifting-cultivation-and-forest-cover-dynamics
