was provided through GB CMA and NC CMA and
the project ran from July 2006 to June 2008.
Background
Natural resource management outcomes often
require landholders to change their current practices.
To aid this process natural resource managers such
as DPI, DSE and CMAs invest in interventions such
as extension and incentives. By understanding
the context of the landholders, it is possible to
understand and segment the ‘market’, allowing better
targeting of extension and incentives programs.
DPI Spatial Sciences Group has a range of land use
and irrigation databases that enable the provision
of property based contextual information such as
irrigated land use area, water use, soil types and
main enterprise. This land and water information
is able to be integrated to identify changes in land
use. Understanding the drivers of change in land use
and the impact of this change on natural resource
management practices and catchment condition of
the SIR is vital in determining appropriate policy and
extension interventions.
Project Objectives
By combining spatial data and social context, the
project is developing a methodology to enable spatial
segmentation of the market for targeting of DPI,
DSE and GB CMA investment. This project builds
on centre pivot irrigation system spatial market
segmentation work completed last year to expand
the methodology to encompass additional issues.
This project also developed an adaptive information
model that combined a range of data sources to allow
for continued identification and validation of natural
resource management spatial markets. This method
allows catchment program managers to visually
compare the effectiveness of interventions to produce
natural resource management outcomes.
Results, Implications and Benefits
This project in 2006-2007 developed and refined a
technique for mapping the location of landholders
that would benefit from adopting a new practice
or technology. The DPI Spatial Sciences Group has
developed a range of land use and irrigation databases
that enable property-based contextual information
(such as perennial pasture cover, irrigated area, soil
types, water use, water trade) to be mapped in a
catchment. An example of a map of the change in
perennial pasture is given below.
A complete loss of perennial
pasture is shown as bright red.
Inversely a new area of perennial
pasture in the 2003-2004 season
is shown as bright green. Light
orange and light green are areas
of relative stability during the time
frame.
