Attitude and/or Skills
Change in Practice /
Behaviour Impact
Project outputsLocal GO, extension agents and scientists responsible for
agricultural technical innovations
Compilation of a
geodatabase covering
all thematic spatial
information related to
the project, including
characterization of the
test sites and study
areas
Learn about new technologiesand where its chances of
adoption is greatest.
Use of domain maps as a
decision support tool tomore effectively scale up
the adoption of new
technologies
Increased chances
of appropriate
technology
adoption and
likelihood of
adoption of sustainable land
and water use
policies.
Extrapolation domainsfor each technology
National level policy makers responsible for water resourceand land management and land use zoning.
Land-use plans based
on trends,constraints,
and interventions
Understand the implications
of different land use plans
under different future
scenarios.
Use the maps as decision
support tools when
planning future
interventions.

WebGIS for GBDC
Why a webGIS?
To disseminate and publicise outputs from G1
To put GBDC “on the map”
To show where we (G1 and other G‟s) work
To control access to the datasets

WebGIS for GBDC
What does this mean?
Amazon cloud platform is “Always on” and not limited by the bandwidth
or infrastructure of any GBDC partner
Data upload to the webGIS is currently managed by IRRI
ANYONE can view the data online
ONLY REGISTERED USERS can download the GIS data – they can
download in bulk or direct to their GIS via a “Web Mapping Service”
We have made a demo page as an example of that it looks like

WebGIS for GBDC
To be discussed
All layers generated by G1 will be on the GIS for view/download. What
other layers are we willing to share for viewing or downloading?
What other information from GBDC could be on there? Survey sites?
Trial sites? Other activities?
WebGIS should be embedded in GBDC web presence.
Need to agree on registration process, and restrictions on use for data
download.
IRRI absorbs cost of webGIS during project lifetime, who will take this on
after the project ends?

What issues are coming out of the project important
from a development context / from a strategic science
context
How to maintain the data sharing environment / partnerships
beyond the project?
The benefit of this within G1 was highlighted in our MSC story, but
how can this be sustained post project? Too many projects „waste‟
precious time & effort in data collection or rather data searching.
What are the mechanisms and incentives at management level ineach institute to promote more transparent access to and
information about data holdings?
Research issues

What issues are coming out of the project important
from a development context / from a strategic science
context
The first extrapolation domains have already identified areas (i.e.
Polder 43/2f) that are highly suitable for intensification. More
areas will follow as more domain maps are produced.
How do we go beyond the remit of G1 and the GDBC to
convince stakeholders to not only refer to these domains but to
actually act up on them?
What is the effect of land tenure, poverty and livlihood constraints
on adoption and what are the strategies to increase adoption
under these conditions?
Research issues

What issues are coming out of the project important
from a development context / from a strategic science
context
What are the potential gains in productivity (from G2) and income
(from G2) in moving from current cropping systems (from land use
map) to more intensive options (from domain maps) and howmany farms/farmers would be affected (from census data)?
Research issues
How will these gains be affected by the future change scenarios?
