Networking, in various forms, has become an international goal of the non-governmental organizations’ (NGOs) world. The main objective is to exchange reliable information quickly and efficiently in order to attain common objectives, and to learn from each other in the process as well. While the contents of NGO networking vary widely, the forms are converging recently to an increasingly extensive use of telematic means.

These means, in their turn, are advancing rapidly to provide worldwide multi-media services which tend to unify digital and analogic information through common carriers in such a way that video, audio, phone and data services would be available in the same wires that today carry only analog voice phone services. ISDN (integrated services digital networks) are operating in Asia, Europe and North America, and portable analog videophones which can connect to each other via a direct call to a satellite channel are commercially available for less than US$250.

Democratizing telematics

The gigantic leaps in digital technology during the 1970’s and
1980’s have resulted in an accelerated democratization of telematic
power, as the home computer of the late 1970’s has become a powerful
data processor and communicator, thus bringing mainframe power of the
mid-1970’s to the hands of the family or university student in the
Northern hemisphere, and the small organization worldwide, at home
appliances’ cost.
Besides an accelerated development of data carrier networks,
telematic technology has also benefitted from revolutionary advances
in signal processing devices and software. This leap has meant the
possibility of connecting two microcomputers through long-distance
calls (using standard voice phone lines), using high-speed error-
correcting modems capable of data compression, to exchange data at
speeds of hundreds of characters per second thousands of kilometers
apart from each other, and automatically discarding (transparently to
each end of the connection) errors due to line noise.
Regular communication being done between Rio de Janeiro and San
Francisco in this way, for example, averages nearly 500 characters per
second. At the phone connection cost of less than a U.S. dollar per
minute, this means that more than ten text pages (3,575 characters per
page) can be exchanged per U.S. dollar between Brazil and the U.S..
The total equipment and software cost (both ends) to permit this
exchange is less than US$5,000.
These communication costs could be further reduced (and probably
the data transfer rate increased significantly) by connecting the two
microcomputers through direct calls (with special modems and 2-meter
transceivers) to non-profit satellite channels such as PeaceSat and
This is the new world of means of communication which thousands of
NGOs worldwide are discovering, learning and practicing. A
democratization of means on an international level unthinkable just
five years ago.

Outreach: NGO networking

Several initiatives by NGOs for taking advantage of the new
techniques have started during the 1980’s. The first significant one
took place in 1984, at the initiative of the late Charles Foubert and
the Italian NGO IDOC– the formation of an international NGO network
called Interdoc. About a year later, most Interdoc participants
started using Geonet, a private European data communications service,
to exchange data with microcomputers. Physically, this network became
a sort of “star network”, in which users link their microcomputers,
via phone lines and data communication carriers, to a minicomputer
centralizing all data exchange among these groups. The center of this
“star” is what is called a node.
Another form of interconnection– the remote bulletin board system
(RBBS)– has been in use by thousands of groups worldwide since the
CP/M-80 operating system (and cheaper floppy disk drives) became
widely available (circa 1980). Hundreds of CP/M-based microcomputers,
connected to voice phone lines, began to offer electronic mailbox (“e-
mail”) and bulletin board services, mostly on a non-profit basis.
Groups have been using these systems to exchange messages and
programs, and to organize specialized information services on themes
such as environment, AIDS, minorities’ rights, small systems
development, and so on. Naturally, the advent of the more powerful IBM
PC systems stimulated migration of these bulletin boards to what would
become the “de facto” standard of the microcomputer market– the IBM PC-
compatible PC/MS-DOS systems. In the meantime, RBBS operators
contributed to the development of methods to interconnect individual
e-mail systems. Another “de facto” standard emerged– the Fidonet
system, proposed by Tom Jennings. Today, networks of RBBS systems
sprawn across the globe, and links to larger systems are being
experimented or in full operation.
At about the same time, groups in England and the U.S. also began
to develop methods and facilities to organize communications networks
using more powerful microcomputers. Borrowing on the philosophy of the
RBBS networks, these groups began to implement a large-scale e-mail
and conferencing system oriented to serve the NGO community on a non-
profit basis. In 1984, peace movements joined forces to foster the
development of this network, and in 1985 an experimental system called
PeaceNet I started its operations in California. In 1986, PeaceNet I
was upgraded to a much more sophisticated service (based on the Unix
operating system) called PeaceNet II. Another network, focused on
environmental concerns, EcoNet, was organized in 1982, under the
coordination of the Farallones Institute in California. In 1987,
Farallones transferred EcoNet to the Institute for Global
Communications– a new NGO created to manage PeaceNet.
Meanwhile, European peace and environmental movements created
GreenNet. Originally operated through the Geonet system, they
installed their own node in 1987. In 1988, a regular link between
GreenNet and IGC was established.
The EcoNet-PeaceNet-GreenNet undertaking shares a common objective:
to build professional network facilities by developing their own
communications services, or nodes, to be used by thousands of
individuals and organizations, at minimum costs. Major differences
between this system and the RBBS network are the scale of operation
(each node is currently capable of handling thousands of subscribers
and requires higher level technicians), advanced connectivity (derived
from the embedded data transfer facilities of Unix), and easier
access: each node is connected to international data communication
carriers and provides high-speed modem lines to allow highly efficient
access through long-distance phone calls.
On the other hand, the system shares an important characteristic of
smaller RBBS networks– modularity. Additional, automatically
interconnected nodes can be installed as local needs arise, and the
capacity of each node can also be expanded as technology advances and
demand for services increases. Since all nodes share the same basic
hardware (high-end microcomputers based on the 80386 microprocessor),
operating system and communications software, maintenance and
developing can be a joint undertaking, further improving the
efficiency of the network.

IBASE: a short story

The Brazilian Institute of Social and Economic Analyses (IBASE) was
founded in 1981 by a group of political scientists, sociologists,
economists, computer experts and others, with international experience
in other countries of Latin America, Europe, the U.S. and Canada. This
international dimension is an important element to explain not only
IBASE’s conception but also the proposed methodology, objectives and
practice of the institute.
IBASE is a non-profit consultancy and research non-governmental
organization (NGO). It is not linked to any political party and has no
religious affiliations. IBASE provides studies, consultancy, data
processing, data communications and other services to rural and urban
workers’ unions, community organizations, popular education and
documentation centers, other consultancy groups, students and others.
Based in Rio but working with groups and other NGOs throughout Brazil
and from abroad, IBASE’s teams total nearly 100 people– including
researchers, helpers, students on assistantships, administrators, and
As a consultancy center and facilitator, IBASE receives several
requests from those groups, usually related to one or more of the
following themes, issues or activities:

– specific studies on the social, political and economic situation of
specific areas in which the groups are active;
– studies to support alternative proposals to official policies;
– production and circulation of audiovisual and printed materials for
training and popular education;
– data communications and data processing services;
– surveys;
– support to seminars and workshops.

The basic goal of IBASE’s work is to contribute to the attainment
of social justice, solidarity, sustainable social and economic
development, and a participatory democracy. The main objective of the
institute to achieve this goal is to facilitate the democratization of
reliable social, economic and political information to civil society,
as well as to contribute in providing adequate and effective means for
this democratization.
Until 1988, IBASE’s activities resulted mostly in regular
publications, books, newsletters, radio programs, audiovisual kits,
articles and studies in newspapers, magazines and other periodicals.
However, since its foundation, IBASE has been closely following up
the telematic revolution. In Brazil, IBASE has been the first NGO to
use microcomputers both for its internal administrative and research
needs and as a tool in support of other groups’ activities. From a
single 8-bit CP/M-80 machine in 1981, to a local area network (LAN) of
more than 25 16-bit MS-DOS computers in 1989, the institute’s data
processing facilities provide services such as: databases, desktop
publishing, statistical analysis and data processing of surveys,
computer consultancy and services to other groups and NGOs, etc. In
addition, since 1985 IBASE has been experimenting with remote exchange
of data between microcomputers. Since that year, IBASE has been a
member of Interdoc.

IBASE and the APC network

The PeaceNet-EcoNet-GreenNet initiative evolved into a proposal to
create an international association to foster the development of non-
profit computer networks, under the name of Associaton for Progressive
Communication (APC). The goals of APC generally coincide with the ones
of IBASE: struggle for social justice and respect for human rights,
concern for the environment, and fostering sustainable development and
participatory democracy. The association shares its resources
(technical expertise, software) among participants, while each node is
fully autonomous to pursue its objectives within the general aims of
In 1988, IBASE agreed to join the APC Network. A project for
setting up a node in Brazil was submitted to the United Nations
Development Program (UNDP). It was formally approved in December of
that year, with financial support from UNDP, IBASE, and from the
Italian government through CESVI (Cooperation and Development), an
Italian NGO based in Bergamo and dedicated to supporting community
development projects worldwide. Among the factors that contributed to
IBASE’s decision to participate were:

– the close coincidence of aims and objectives of the APC initiative
and IBASE’s;
– the specific interest of IBASE in contributing to developing
alternative means of information exchange;
– the possibility of providing a service not only to Brazilian but
also to other Latin American groups at costs much cheaper than using
commercial services;
– the relatively advanced data communications system available in
– the proven expertise of IBASE in working with microcomputers.

The ALTERNEX Network Node

To further develop its expertise in data communications, in 1988
IBASE installed an X.25 port to Brazil’s packet switching system
(RENPAC). Through a technical agreement with the Brazilian
Interdisciplinary AIDS Association (ABIA), IBASE designed a remote
access database system on AIDS. It allowed any user to obtain
information on hospitals, treatment methods, prevention, etc, by
connecting a microcomputer to the RENPAC system via a local telephone
call from most of the larger Brazilian cities, and also from other
In March, 1989, IBASE started to operate an RBBS system based on
Tim Stryker’s MajorBBS software– it was rewritten to work with the
X.25 port. At the same time, IBASE’s technicians, with advice from IGC
experts, started to assemble an 80386 machine to run Unix– the
operating system of the APC network.
These experiments were extremely important for evaluating the
consequences of proposing to maintain a round-the-clock, reliable
communications service by a non-profit NGO. This involved a
significant operational reorganization and infrastructural
improvements (such as uninterruptible power supply, systematic back-up
of users’ transactions, efficient on-line maintenance procedures,
hiring of higher level computer experts, and so on).
On July 18th, 1989, the ALTERNEX Node started to operate its full
e-mail and conferencing services from the Unix machine, automatically
interconnected to the other nodes of the APC network.
In the meantime, similar nodes were being installed in Australia
(Pegasus), Canada (The Web), Nicaragua (Nicarao), and Sweden
(FredsNaetet). At the time of this writing, all these nodes are also
fully operational, thus constituting a worldwide seven-node non-profit
network now interconnecting more than 5,000 users.
The following list indicates the current numbers of users in each
node of the APC network (as of February, 19, 1990):

IGC…………. 3,661
GreenNet…….. 668
The Web……… 505
Pegasus……… 348
ALTERNEX…….. 159
FredsNaetet….. 117
Nicarao……… 105

Total……….. 5,563

Through gateways to Internet, Bitnet, Geonet, and to commercial
services such as DASNet, this user base can reach dozens of thousands
of organizations and individuals in most countries.
Since August, 1989, a direct phone line allows users to connect to
ALTERNEX without having to go through the packet switching system.
This is especially useful for users of the Rio de Janeiro area (where
hundreds of NGOs are located). This line is capable of MNP error
correction, and IBASE supplies communications programs to emulate
error correction with standard modems, so users are able to connect
without noise-induced errors even with long-distance calls, using
cheap 1200 baud modems. These facilities are currently available in
all nodes of the APC network.
The APC network currently provides e-mail and conferencing
services. Automatic interconnection means that a user in any node can
exchange messages with users of any other node, and also participate
in more than 60 networked conferences on themes such as external debt,
tropical forests, Central America, environment, health, and others.
Networked database systems are being tested and should be implemented
during 1990.

Perspectives of the network

Although a great deal of the programming for the system is already
developed, the network demands the availability of Unix programmers in
each node– both for maintenance and joint technological development.
In the case of IBASE, for example, technicians are working on a system
which will allow the DOS-based LAN to share the X.25 port with the
Unix machine– thus allowing services such as remote access databases
to be run from standard MS-DOS computers, and permitting local users
to access the node from any computer in the LAN. Once this software is
fully debugged, it will be available to other nodes. Thys system could
allow, for example, the simultaneous operation of a Fido system
through the same X.25 port, stimulating interconnection to Fidonet.
There is also the need for an operator and a secretary to handle
administrative tasks such as accounting, user registration and
billing, etc. Other running costs include leasing of communication and
phone lines, preparation of newsletters, manuals, mailing, etc. The
current estimate of running costs for the ALTERNEX Node is nearly
US$6,500/month. Since its official opening, the node has seen its user
list grow to nearly 160 groups and individuals by February, 1990.
Current projections indicate a total of nearly 450 paying users by
mid-1990 (thus permitting self-sufficient operation), although
participation by Brazilian NGOs has not yet caught up as much as
initially expected. The main reasons for this are:

– lack of understanding of the potential of the network;
– difficulty to assimilate the new technology involved;
– lack of resources to purchase microcomputers and phone lines (a
phone line in Brazil must be purchased, at costs at times higher
than US$2,000).

As to the first two reasons, we believe the animation campaign
being carried out by IBASE and other NGOs is overcoming these
limitations. The last one is hard to solve– most of the more than
3,000 Brazilian NGOs are very small, running mostly on voluntary work.
As an alternative to this economic difficulty, IBASE is proposing with
several other larger NGOs the setting up of “community e-mail
agencies”– rooms equipped with a microcomputer and printer,
connectable to ALTERNEX, and permanently open to smaller community
Our estimates are that these “agencies” could be implemented in two
months in at least 25 of the largest Brazilian cities, handling an
average of 25 users each. Many human rights and environmental
organizations could benefit from these “agencies”. IBASE is presently
seeking financial support to help in setting up the basic hardware and
phone lines for this project (estimated at about US$6,000 per
“agency”, including the phone line). IBASE already maintains its
“agency”, with data communications, telefax and telex services
available to groups in Rio de Janeiro on a non-profit basis.
Another project proposes a revolving loan fund managed by a group
of well-known NGOs to provide financial means for smaller groups to
install the basic equipment to connect.
An interesting development is
the growing number of users from other Latin American countries
(Chile, Peru, Uruguai, Ecuador, Argentina, Colombia), as well as users
from Italy, West Germany and Japan.
Another important development is UNDP’s interest in continuing to
support the expansion of this network in Latin America. A regional
project to study ways to expand the network is being carried out by
UNDP, in consultation with IGC, IBASE and CRIES (the NGO in Nicaragua
which operates the Nicarao node).
Finally, a project to start a new APC node in Moscow– which would
allow Eastern European groups and individuals to participate in the
network– is being implemented, with probable starting date for full
operations in May, 1990.

IBASE, studied naval engineering in Sao Paulo, and holds an M.A. in
Economics from York University (Canada), where he also undertook
doctoral studies in Social and Political Thought. He has been involved
with microcomputer applications since the end of the 1970’s.
