Net Benefits from growing lucerne (Medicago sativa) on the Broken Plains of north eastern Victoria AgEcon
Trapnell, Lindsay N.; Malcolm, Bill.
Clearing of trees and native vegetation over the past 160 years has led to increasing rates of dryland salinization in the Goulburn-Broken Catchment area. In its dryland section, within the Goulburn Highlands, South West Goulburn, and the Broken Highlands subcatchments, hydrologic balance exists. But in the Riverine Plains comprising the Goulburn and Broken Plains sub-catchments, where average annual rainfalls are less than 600 mm per annum, it will be many decades before hydrologic balance is achieved. This study is set in the Broken Plains sub-catchment where over the next 100 years, it is expected that deep drainage of annual rainfall will cause watertables to rise to within two metres of the ground surface. Such rises of groundwater will lead to marked...

An Investigation into the Net Benefits of Revegetating Agricultural Land with Indigenous Species in the Dryland Section of the Goulburn-Broken Catchment Area AgEcon
Trapnell, Lindsay N..
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.
