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.

Megan Smith, Vice President, New Business Development and General Manager, Google.org., argued that greater interconnectedness achieved by information technology is a major liberating force in the world. Whether it is aiding the coordination of protests or increasing transparency of governments, the exchange of information has huge benefits. This is not a new phenomenon. In places where people have been able to exchange information easily, social progress has followed. Megan cited the example of Seneca Falls, New York where the canal system allowed for extensive communication; it became significant in both the women's rights and abolition movements.

While a large proportion of the world is benefiting from greater interconnectedness, Africa still lacks the infrastructure to take full advantage. Submarine fiber optic cables are necessary for quick and cheap internet cables and many African countries, particularly in the east, are not connected to these, relying instead on satellites. This is likely to change over the next few years, bringing great potential for further development.

The mission of Google.org is to use technology to drive solutions to global challenges such as climate change, pandemic disease and poverty. The organization was set up as part of a commitment to devote approximately one percent of Google's equity plus one percent of annual profits to philanthropy, along with employee time.  Google.org now places its strategic focus on those projects that can leverage the resources of Google staff, particularly its engineers.

Current projects that harness the power of information include:

• Google Flu Trends: This uses aggregated Google search data to estimate flu activity up to two weeks earlier than traditional methods. This system has almost 90% accuracy in real time flu prediction and is therefore an extremely useful tool for health delivery agencies. It is now being used in 30 countries. Google is also starting to work in Cambodia to collect data around SARS.
• Google Power Meter provides a system for consumers to understand their in-home energy use and to take steps to reducing this. The Meter receives information from utility smart meters and in-home energy management devices and visualizes this information on iGoogle (a personalized Google homepage).The premise underlying this project is that greater information is going to be crucial to tackling climate change and consumers ought to be able to be empowered to make informed decisions about their energy use.
• Disaster relief: In response to the Haitian earthquake, a team of engineers worked with the U.S. Department of State to create an online People Finder gadget so that people can submit information about missing persons and to search the database. Google Earth satellite images have also been used to document the extent of damage.
