ABSTRACT
Landuse systems are open systems characterised by inputs, outputs, transfers and transformations of material and energy, and operating in parallel with hydrological, nutrient and energy cycles (Figure 7.1). In a general context, landuse systems may be classified as agricultural or non-agricultural. Agricultural systems may be further subdivided into arable, pastoral and forestry practices, while non-agricultural systems focus on urban, industrial, recreational and leisure activities.
