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.

Elizabeth Eagen introduced the Human Rights Data Initiative at the Open Society Institute - a project to support human rights organizations in using technology to further their goals.

The management of information is crucial to human rights work but the majority of organizations are at a very early stage of being able to utilize new technologies. For organizations tracking human rights violations, the stream of work is continuous and leaves little time for strategic thinking about the adoption of new tools.

When thinking about the role of technology, there has been a tendency for human rights organizations to focus on the way that they communicate their work more widely; for example, investing in a better website design. This neglects more fundamental issues around the management of the core databases and information flows that drive human rights work. Many of the current developments in the field of technology for development enable organizations to communicate issues in a powerful way. Visualizations using satellite data - for example to show the extent of damage resulting from conflict in Georgia - are an effective way of conveying a situation quickly. But they lack the details human rights organizations require: who was attacked and when; are the buildings civilian or military targets? There is really no substitute for the kind of human evidence required to build a convincing case that human rights violations have taken place.  Often much of this case is paper based. This presents a real challenge of how to capture all of this history and make it manageable.  

The Human Rights Data Initiative project is in the process of giving human rights organizations in the Open Society Institute network the opportunity to think about what kind of technology tools might contribute best to their work. This project requires gaining a better understanding of how the organization operates and what barriers might exist to utilizing technology. This might be something as basic as poor internet connection or as complex as an overall organizational culture. The goal is for human rights groups in the network to reach a position where they better understand their technology needs and how best to fill them.
