000170844 520__ $$aThe Liverpool Plains in the north western slopes of New South Wales are a
highly fertile cropping area. Groundwater levels are rising in the catchment
and the emerging soil salinisation is increasingly affecting agricultural
productivity. This trend is expected to continue unless land use methods that
reduce accessions to the groundwater are adopted. A catchment model to
determine the economic costs and benefits of the management of dryland
salinity is proposed in this paper. This research is part of an interdisciplinary
project that will incorporate data and other modelling work currently being
undertaken by a number of different agencies including ABARE, AGSO,
CSIRO and CaLM. The Liverpool Plains in the north westenl slopes of New South \Vales are a

project that will incorporate data and other modelling work currently being
undertaken by a number of different agencies including ABARE, AGSO,
CSIRO and CaLM. The analysis will use a farm level mathematical programming model which
will be embedded in a catchment model that incorporates groundwater
movement. Management differences across the catchment will be represented
by different farm submatrixes. The catchment-scale dimension of dryland
salinity will be modelled by establishing spatial and temporal hydrological
linkages between model farms. This will allow for a quantitative analysis of
policies that are designed to rectify the externalities associated with managing
the water balance of catchments. This work is undertaken as part of the
National Dryland Salinity Management Program.
