Benefits ascribed to the revegetation of farming landscapes include enhancement of biodiversity, reduction in the advance of dryland salinity, sequestration of greenhouse gases, control of soil erosion, greater protection of agricultural activities from adverse weather conditions and an improved aesthetic value of rural lands. In this paper, economic analyses were performed to determine the net benefits to landholders of carrying out revegetation. Where the net benefits were insufficient to allow reasonable returns to be earned on the investment of marginal capital, an assessment was made of the amount and type of assistance that would be necessary to encourage landholders to adopt this improved system of land management.
