First reason of scant use of agrometeorological services
Lack of cooperation between
the institutions providing information and relevant advisories andthose responsible for their transfer to the farming community
Second reason of scant use of agrometeorological services
Insufficient education and training of the user community, including the farm advisory services, that provide specific agricultural advice from general weather information

19
Of course in each of the three domains one makes use of data, research, education/training/ extension and policies, but only in the C domain are they to be considered of a purely supportive nature. In the B and A domains and in E2 and E1 they are (or should be) used/carried out in action.
This is an essential difference that so far is most often not recognized, because, following developments in developed countries, we are everywhere too obsessed with methodologies and science as such.
The closest action is most often in E1. These actions are the bulk of our good intentions to mitigate impacts of disasters and to use the four ingredients of the support systems in applications in the real world.
Unfortunately they have often little to do with the needs of the A-domain, in which meteorological services should deliver support for users/farmers’ decisions/actions.
20
E2 supporting actions are actual meteorological services, that relief
constraints under the livelihood conditions of the local users/farmers.
This means that needs assessments with respect to meteorological services for the user/farming systems concerned
should come first.
• However, the pushing is from right to left.• Exemplifying from the relation between
industry and physics in the fifties, a pushing from left to right is possible.
• Changes in what pushes breeding research show that the same is possible in meteorological services: A-domain guides C-domain.
21
curricula at post graduate and lower levels curricula at post graduate and lower levels should pay attention to the enormous should pay attention to the enormous
need for training need for training of meteorological extension personnel at the of meteorological extension personnel at the
intermediate level.intermediate level.
In non-industrialized countries, training of intermediaries would go a long way in solving these problems for various groups of all but the richest and best educated farmers. Training programs at all levels must therefore be adapted to national and regional needs.
22
In recent operational developments this includes developing extension around the establishment of meteorological services.Particularly in all poorer countries.Intermediaries should there be
the ones in direct contact with the user communities.
The first kind of meteorological intermediarieswould be close to the centers where the meteorological information useful for decision-makers is generated.
The second kind of (meteorological) extension intermediaries should be closest to the users/farmers and operate exclusively in the A-domain, using E2 guidance. They should learn to articulate the needs of the user/farmer communities better and detect meteorological components that need attention.
23
The education and in service training of these two kinds/classes of meteorological extension intermediaries is an essential part of the new approach,that appears necessary in education, training and extension in agricultural meteorology as well as in other applications of meteorology.
A 2007 World Bank Report A 2007 World Bank Report on poverty in Indonesia, on poverty in Indonesia,
that was highly reviewed, says:that was highly reviewed, says:
““Change happens when intermediaries Change happens when intermediaries get involved to help the poorget involved to help the poor””
This definitely also applies toThis definitely also applies toour kinds of intermediaries.our kinds of intermediaries.

The bottom lineWithout at least some quantification, qualitative descriptions of uncertainty convey little, if any, useful information.The climate assessment community is gradually learning this lesson. As you know Steve Schneider and Richard Moss have worked hard to promote a better treatment of uncertainty in the work ofthe IPCC. At my insistence, in its 2000 report the U.S. national assessment synthesis team gave quantitative definitions to five probability words:

BMGBMGConcluding RemarksConcluding Remarks
We have described the procedures of high resolution climate forecasting applied in Indonesia for various agricultural purposes based on dynamical and statistical downscaling in combination with some advanced statistical techniques
Lessons learned from the implementation of the techniques in producing high resolution climate forecasts at regency/district scale in Indonesia indicate some advantages of this multi-model approach:• computationally inexpensive • provide local information in the form of
probability density function risk management
Crucial impedances in the dissemination of climate information: diversity in “language”, socio-economic behaviours, institutional framework/arrangements
