Lecture 5

Defining ICTs

• Standard definitions: ICT (information and communications technology - or

technologies) is an umbrella term that includes any communication device or application, encompassing: radio, television, cellular phones, computer and network hardware and software, satellite systems and so on, as well as the various services and applications associated with them, such as videoconferencing and distance learning. ICTs are often spoken of in a particular context, such as ICTs in education, health care, or libraries.

Lecture 5

The technologies

ICT Fig. 1: ICT for Development: Range of Technologies and Users Relevance Definition: The term “Information and Communication Technologies” (ICT) refers to technologies designed to access, process and transmit information. ICT encompass a full range of technologies – from traditional, widely used devices such as radios, telephones or TV, to more sophisticated tools like computers or the Internet. The mix of technologies used should be determined mainly by the specific local context and demand. (Weigel and Waldburger, 2004, p.19)

Lecture 5

Defining ICT4D

ICT4D (Information and Communications Technologies for Development) is an initiative aimed at bridging the digital divide (the disparity between technological "have" and "have not" geographic locations or demographic groups) and aiding economic development by ensuring equitable access to up-to-date communications technologies. Information and communication technologies (ICTs) include any communication device -- encompassing radio, television, cellular phones, computer and network hardware and software, satellite systems and so on, as well as the various services and applications associated with them, such as videoconferencing and distance learning. The United Nations, through its UN Development Programme, actively promotes ICT4D as a powerful tool for economic and social development around the world.

Lecture 5

Defining ICTs is problematic

• ICTs (adapted from Fillip) capturing technologies (cameras, tape recorders) storage technologies (film, CD-Roms, digital media) processing technologies (software), communication technologies (telephones, local area

networks) display technologies (monitors) GIS (combine many of the above)

• ICTs are not particularly new Need to be very specific about what we mean Invariably people claim to use inclusive definitions, but

then concentrate on computers and the Internet

Page 9: ICT for Development The technologies and their uses ICT4D Lecture 5 Tim Unwin.

Lecture 5

A framework for thinking about ICT4D technologies

• Most definitions begin with the technologies And are thus ‘technology’ led Rather than seeing technologies as tools

• Let’s begin with information and communication And then see what technologies can help us enhance these

And use information and communication for development purposes

• A focus on poor and marginalised communities

Page 10: ICT for Development The technologies and their uses ICT4D Lecture 5 Tim Unwin.

Lecture 5

Information

• What kinds of information are there?

• Examples of how information can be of help to poor and marginalised people?

Kinds of information

• Kinds of information ****

• Uses by the poor ****

Page 13: ICT for Development The technologies and their uses ICT4D Lecture 5 Tim Unwin.

Lecture 5

Information

• Generally produced for a specific purpose By ‘someone’ for a particular reason

Must be in a form that can be readily understood by intended audience

But often later used for different purposes

• Requires media for dissemination• Rarely dynamic

Can become out of date unless revised

• Needs to be readily findable and searchable

• Value in terms of supply and demand Relationships between these are not straightforward

Page 14: ICT for Development The technologies and their uses ICT4D Lecture 5 Tim Unwin.

Lecture 5

Communication

• How do we communicate? What kinds of communication are there?

• Examples of how communication can be of help to poor and marginalised people?

Lecture 5

Communication

• Involves interaction Synchronous and asynchronous Space-time implications

• Communicators must understand each other, and must wish to be understood Languages, codes, rules of communication

• Uses many different senses Hearing, sight, smell, touch, taste

• Those who control the communication media wield considerable power

Page 18: ICT for Development The technologies and their uses ICT4D Lecture 5 Tim Unwin.

Lecture 5

ICTs: The technologies

• Production Capital seeks to reduce production costs and expand markets ICTs are products And yet are also capable of reducing costs and expanding markets

High innovation costs, and yet relatively low production costs Technological innovation to ensure continued sales• A challenge to sustainability

Separation between Production of the enabling media Production of the content

Page 19: ICT for Development The technologies and their uses ICT4D Lecture 5 Tim Unwin.

Lecture 5

ICTs: The technologies

• Consumption Of both the technologies, and the messages transmitted thereby

Technologies allow new modalities of consumption

• Exchange ICTs enable exchanges of

Information Finance Communication

But little exchange value in themselves High costs of recycling Environmental costs usually not taken into consideration

Lecture 5

Distribution: the digital divide

• The ICT maps of Africa http://www.uneca.org/disd/ictmaps.htm

• Basic ICT indicators all show markedly uneven distribution Spatially, and at different scales Socially

• The divide is in terms of Access

Physical Cost

Understanding Relevance

Page 22: ICT for Development The technologies and their uses ICT4D Lecture 5 Tim Unwin.

Lecture 5

Conclusions

• Need to shift the balance away from the technologies themselves, and to an understanding of information and communication

• How can technologies facilitate these processes for the poor and the marginalised?

• Emphasis on plurality of media to deliver most appropriate solutions

• Will the existing power relationships really enable the digital divide to be bridged?
