Who are the clients

cess can be obtained through the appreciation, in what- ever form, by this community of the services rendered.
As one of the first steps, it should identify the ‘clients’, their requirements, and their evaluation of
the value of the ‘products’ delivered and then offer the desired product to the client in the most appro-
priate manner. The delivery of the products relies on the availability of a readily accessible data base, the
knowledge of, and access to, an ‘inventory’ of possi- ble application techniques, an infrastructure trained
personnel and the physical means to produce the products, and an appropriate product dissemination
system. The fine-tuning of the process requires a con- tinuous feedback on the technical, environmental and
economic benefits of the system.
Improvements in agricultural production may well occur first where the efficiency of the inputs into agri-
culture is highest. Such inputs are of different nature: genetic material, energy, water, adapted use of the soil
and of the landscape and plant nutrients, management, and of course the weather. Of all those inputs only
the weather is free of charge Baradas, 1978, and its influence has been, perhaps because of that reason,
relatively little exploited Rijks, 1991. User-tailored weather information for planning, adaptation of the
system, and day-to-day operations involving the dosage and timing of application of inputs, is one of
the major factors that can increase the efficiency of these measures and help to reduce the risks on the
investments made. This aspect defines one group of clients. Another group is involved in general matters
or in activities that precede or follow after production has been achieved: marketing, processing, consumer
orientation, legal and administrative matters and en- vironmental issues.
The relation with the client takes into account: •
A description of the basic factors determining the atmospheric environment for agriculture solar radi-
ation, temperatures, water availability in all its forms, humidity, the wind regime and other
characteristics, such as weather ‘hazards’;
• A description of the requirements for each appli-
cation and client; •
A quantitative formulation of the relationships that exist in respect of the effects of weather on vegeta-
tion, soil, open water and animals and the recipro- cal effects of these ‘surfaces’ on their atmospheric
environment; and •
A process to ‘match’ the requirements of the users to the meteorological conditions that may exist,
to optimize the use of all the resources provided by the weather and the other inputs and to min-
imize the influence of adverse conditions Rijks, 1986.
While at one time the meteorological community
may have made a distinction between the use of weather and of climate information, a farmer makes
many decisions by combined use of the two Rijks, 1984:
Climate Weather
choice of farming timing, extent of land
system preparation, land layout
choice of crops date of planting
choice of optimal variety choice of alternative
variety choice of farm
actual use of equipment; equipment
day-to-day farming operation
choice of row width within-row distance of
plants choice of irrigation
timing and amount of water given
choice of pest control timing and extent
system of controls
Agrometeorology can play its role if the clients per- ceive that its products have increased the value of their
agricultural production potential, and made actual production approach the potential at equal cost of in-
puts. In short, clients must feel that they are customers ‘buying the best deal’.
