Kentaro Toyama is a visiting scholar at the School of Information at the University of California, Berkeley.  Until 2009, he was assistant managing director of Microsoft Research India, which he co-founded in 2005.

Kentaro identified a number of myths that surround the field of ICT4D and argued that these can confuse our thinking about the proper role for technology in addressing development problems.

Myth 1: Technology x will save the world: The history of writing on technology shows that each new advance tends to be greeted with unbridled enthusiasm about its potential impact. Where once people were convinced television could solve all social and political problems, today we are putting that burden onto mobile phones.

Myth 2: Poor people have no alternatives:  We can often assume that technology is the only way that poor people will be access certain goods. In reality, there are usually non-technological routes to information and services that are free and therefore preferable.

Myth 3: ‘Needs' are more pressing than desires: A high proportion of the income of the very poor goes on what Western observers might view as ‘luxury' items: (music, photos, festivals & weddings) rather than ‘basics' such as healthcare.

Myth 4: ‘Needs' translate into business models: Building a business model around the needs of poor communities is possible, but there are significant barriers. Poor populations are harder to reach, and they may not want to pay for the services you provide, even if their value seems obvious to you.

Myth 5: If you build it, they will come: Spending is not always rational. An eye hospital in India offers extremely high quality cataract operations for free and covers all related costs. 10% of those offered the service will still refuse to have the operation.

Myth 6: ICT undoes the problem of the rich getting richer: In contexts where literacy and social capital are unevenly distributed, technology tends to amplify inequalities rather than reduce them. An email account cannot make you more connected unless you have some existing social network to build on.

Myth 7: Hardware and software are one-time costs: Kentaro estimates that the average One Laptop per Child will in fact cost $250 per child per year to cover breakage, connectivity, power, maintenance and training.

Myth 8: Automated is always cheaper and better: Where labor is cheap and populations are illiterate, automated systems are not necessarily preferable. Greater accuracy may be another reason to favor voice and human mediated systems.

Myth 9: Information is the real bottle-neck:  Those in the ICT4D world are prone to overestimate the significance of information gaps. Even if you connect a farmer to an agricultural expert via a PC, there are a host of other barriers to be overcome before he can actually increase his yields, including: literacy, poor transport links, and a lack of volume buyers for seeds, pesticides etc.

Kentaro contends that when technology makes a difference in development, it is always as much to do with the input of committed and competent individuals and organizations. Despite this, the focus when reporting ICT4D projects quickly slips into extolling the virtues of the technology itself, not the human component. This says much about the seductive quality of technology. Myths about its potential persist because we have a strong desire to see the triumph of clever ideas and ingenuity, and to believe that one time catalytic investments can have such an impact. The reality is always more complex.

Eric Brewer is Professor of Computer Science at the University of California Berkeley where he leads the Technology and Infrastructure for Emerging Regions (TIER) research group.

Eric spoke about the role for technology in effective development strategies at the base of the pyramid.

The history of development to date has been characterized by large agencies funding big projects with strings attached, usually in the form of debt or demands for political allegiance. These kinds of projects are hampered by their scale and the requirement to work with corrupt governments. They typically include little role for new technology as projects move slowly and lack the expertise to facilitate this.

Outside the sphere of traditional development, technology is having a major impact on economic prosperity. The mobile phone revolution, driven by bottom up demand, provides enormous advantages to any worker operating in a large radius. A taxi driver given a mobile phone, for example, will increase his revenue by 60% on average. Other bottom-up businesses have seen major success. The Village Phone scheme, which runs as a franchise model with capital coming from microfinance, now covers the majority of Bangladeshi villages. A village phone lady will make on average two times the income she would have done from farming.

However, the mobile phone remains a largely urban phenomenon since cellular networks require a certain density of users before they can economically justify the installation of a base station. The availability of an internet connection is crucial for the viability of businesses and services in rural areas.  WiFi-based Long Distance networks (WiLDNet) are emerging as a potential low-cost alternative to traditional connectivity solutions for rural regions. Unlike mesh networks, which use omni-directional antennas to cater to short ranges, WiLD networks are comprised of point-to-point wireless links that use directional antennas with line of sight over long distances.

Eric's Berkeley research team has partnered with Aravind Eye Hospital in Theni in the southern India state of Tamil Nadu to use this technology to address the problem of blindness in the region, 70% of which is treatable. The long-distance wireless network they have installed is allowing eye specialists to interview and examine patients in five remote clinics via high-quality video conferencing. 25,000 patients have recovered sight using this system and it is set to expand to 50 centers covering 2.5 million people.

Eric's team has also worked on software that addresses local educational needs in developing regions. In poorly resourced schools, students will often be sharing a mouse and computer screen with a group of others. Metamouse gives each student their own mouse to use; when answering questions all users must agree on a location before progressing. This encourages collaboration between students and has had impressive results in boys in particular, with a 50% improvement in scoring compared to each user having their own PC.

Jenny Aker an Assistant Professor in the Economics Department and Fletcher School of Law and Diplomacy, Tufts University, provided an overview of the welfare impacts of mobile technologies and how current research is testing our assumptions about the benefits of mobile phones for individuals in developing countries.

Mobile phones are used by some of the poorest people in the world; even at the country ranked 160 in the UN's Human Development Index, levels of adoption of mobile phones are at 50%. There are few systematic studies looking at why people adopt mobile technology, but those that exist suggest there are correlations with higher income levels, trading professions and an urban location. Mobile phone coverage across Africa is now extensive. Research shows that roll out by mobile phone companies is determined by factors including the size of population, the costs associated with terrain, quality of road access and the operating environment (whether there exists a competitive liberalized market).

Identifying the positive impact of mobiles can be difficult because they have so many uses, making assessment of costs and benefits problematic. Mobiles are also only pseudo private goods since they are often shared and benefits extend beyond the owner.  Despite these difficulties, a number of researchers have demonstrated the impact of mobile phones in the developing world. Robert Jensen's paper found that the introduction of mobiles into the fishing industry in Kerala, India resulted in reduced price discrepancies and significant welfare benefits in the form of increased profits for fishermen and reduced waste. Similarly, Jenny's own study of grain markets in Niger found that the use of mobile phones reduced price discrepancy and enhanced welfare through increased trader profits and reduced average consumer prices.

As well as these externalities from the IT sector, we are also seeing deliberate attempts to harness the potential of mobile phones, from private sector services (e.g. the provision of mobile money transfers such as M-Pesa) to non-profit development projects using mobiles in diverse contexts including health, governance and market information. Jenny is currently working on a project that will examine how mobiles can improve literacy in Niger. A pilot of Project ABC over the next three years will assess how access to mobile phones can complement traditional literacy lessons by giving people the chance to practice their literacy skills via SMS. Early results suggest significantly higher performance in literacy testing by groups using mobile phones.

If mobiles have genuine welfare impacts then ensuring access becomes a key policy concern. Jenny highlighted the importance of continuing liberalization of telecoms markets in Africa, maintaining fair and transparent legislation and reconsidering ICT taxes (in some countries mobiles are taxed as a luxury good). But while mobiles can enhance the delivery of and access to resources and information, we should be wary of viewing them as a development panacea since they cannot replace basic infrastructure investments such as power and roads.
