COUNTRY ALMANACS:
Moving GIS into the
Mainstream of Agriculture and Natural
Resource Management
Geographic
information systems (GIS) offer powerful tools for managing and analyzing
spatial information to assist in agricultural development and natural
resource management. Mainstream use of GIS has been hindered by high
software and hardware costs, the need for specialized training, limited
availability of data, and potential end-users' lack of familiarity with
GIS applications.
The Country Almanacs move GIS into
mainstream use by providing readily accessible tools and data for
characterizing and analyzing geographic variation in relation to
agricultural concerns. Almanacs provide cutting-edge GIS tools for users
who are not GIS specialists. Researchers, policymakers, and administrators
have immediate access to GIS information at the moment they need it,
directly from their desktops or laptops.

About the Almanacs
Developed at the Blackland Research and
Extension Center (BREC) of the Texas A&M University System, the
Almanacs provide foundation data on climate, topography, land use, human
population density, and other features in a widely used format on CD-ROM.
Users can easily query and display the
data, varying the choice of map symbols and colors according to their
needs. The "site similarity" tool provides a particularly
powerful mechanism for identifying regions with characteristics similar to
a specific site. Any subset of data can be exported as tables or graphs or
in a standard GIS format.
Almanac users can either load their own
data into existing Almanacs or create new Almanacs from scratch. In this
way, Almanacs serve to disseminate spatial data and at the same time to
safeguard the data and other important information that form the
institutional memory of a research organization.
The software shell has additional non-GIS
tools such as a database query for crop trial results and a digital
document library. The shell provides a framework for researchers to
assemble a "tool kit" of agricultural software, in which
individual tools including crop models, impact assessment tools, or
databases can be managed easily from a standardized user interface.
Almanacs are available for many countries
and more will be available soon (see table). Almanacs for developing
countries are distributed at no charge.
Two-day training workshops enable potential
users to dominate the basic functions of the Almanacs. Participants in the
workshops give the design team invaluable feedback on tools and data
needs, ensuring a close match between users' requirements and software
development priorities. As an increasing number of partners have
collaborated in developing the Almanacs, the utility of the software has
increased.
Who Uses the Almanacs, and
Why?
Users come from a broad range of
disciplines and management areas in national and international research
centers, universities, private companies, and non-governmental
organizations. They include genetic resource specialists, breeders,
agronomists, livestock specialists, research policy advisors, and research
managers. It is particularly encouraging to see widespread use among CGIAR
Centers, including CIMMYT, CIP,
ICARDA,
ICRISAT,
ILRI, and
IPGRI.
Examples of Almanac applications include:
-
Delimiting major wheat production regions of Ethiopia (Box
1).
-
Characterizing climatic conditions for maize production in the Mid-Hills
of Nepal.
-
Assisting site selection for research with small-scale maize farmers in
Zimbabwe (Box 2).
-
Identifying regions of Ethiopia prone to waterlogging.
-
Planning marketing strategies in Zimbabwe for a private seed company's new
groundnut varieties.
-
Examining and reproducing results of a major GIS-crop simulation exercise
that assessed the potential of conservation tillage in Jalisco, Mexico.
-
Facilitating collection of district-level crop and livestock production
data in Kenya by showing potential data providers how their data will be
used.
-
Training researchers in the potential uses of GIS.
Opinions of the utility and accessibility
of the Almanacs are overwhelmingly favorable (Box 3).
Almanac Support and
Information
The Country Almanacs include an extensive
on-line help. BREC provides e-mail-based support and maintains a website
for posting new datasets and utilities (http://www.brc.tamus/char/). Tutorials are
available for specific countries.
To date, in-country training has largely
been organized through CIMMYT in collaboration with regional networks,
national research services, and other international research centers. The
Almanac team is exploring options for developing further in-country
training and support capacity based in national agricultural research
programs or universities.
Future Plans
Demand for the Almanacs is growing rapidly
as potential users learn about their practicality, accessibility, and
relevance. The development team actively seeks new partners and support,
both within countries and across regions, to meet this demand. Partners
should provide local leadership in training and maintaining data sets.
They are welcome to participate in developing the software, according to
their needs and capacities. To date, the Almanac development team has
focused on assembling country-level data, but the team hopes to give
greater emphasis to higher resolution data, which holds great promise for
increasing farm-level impact.

1. Almanacs
at Work: An Agroclimatological Characterization of Wheat Production
Regions of Ethiopia
|
Ethiopia's current annual wheat production
of approximately 1.3 million tons is insufficient to meet domestic needs,
and the country imports as much as 50% of its wheat requirement. The
national research organization, EARO, was interested in identifying new
areas where wheat could be grown. The Ethiopia Country Almanac was used to
analyze climatic data related to current and potential wheat production
areas.
Based on consultations with Ethiopian wheat
scientists and examination of a published map approximating the geographic
distribution of wheat production (Belay Simane et al. 1999), traditional
rainfed wheat production areas were best described as those receiving 350
mm or more precipitation and having mean minimum temperatures of 6-11C
during the wettest quarter (the green areas in the map). When the minimum
temperature range was extended to 13C (orange areas), the potential wheat
growing area almost doubled, emphasizing the importance of growing season
temperature in limiting the current wheat area. By developing wheat
varieties or agronomic practices suited to a higher temperature range, the
research system might make wheat production an option for more farmers.

Almanacs at Work: Selecting Sites for Farmer Participatory Research in
Zimbabwe
|
CIMMYT is investigating the strategies that
Zimbabwe's smallholder maize farmers use to deal with climatic risk. This
participatory research project (funded by ACIAR) complements broader
activities of SoilFertNet, which develops practical methods for
smallholders to maintain or improve soil fertility in their cropping
systems.
To guide the selection of locations for
farmer participatory research, the Zimbabwe Almanac was used to compare
the relative "areas of influence" or similarity of prospective
research sites based on climate and population variables. Regions were
considered similar to the proposed site at Makaholi, for example, if
precipitation, evapotranspiration, and maximum and minimum temperatures in
the rainy season (five wettest months) were within 10% of conditions at
Makaholi (the shaded areas on the map). Population density was a further
criterion for site selection (Deichmann 1997). When human population
density was interpolated from 1990 estimates for the areas that were
similar to Makaholi, total population within the areas was approximately
1.6 million people, which more than justified the selection of Makaholi as
a site for the participatory research.

Positive Feedback from Potential Almanac Users
|
Almanac users report
a high level of satisfaction with the software and data. For example, a
two-day workshop was recently held in Kathmandu, Nepal to present the
Nepal Almanac to 25 agronomists linked to an SDC-funded project to improve
maize production in the Mid-Hills. A brief evaluation at the end of the
workshop elicited extremely positive responses. Participants in workshops
in Kenya and Zimbabwe showed similar levels of enthusiasm.
