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.

Kim Scott, Director AdSense Online Sales & Operations at Google, explored the potential of new technology for both increasing decentralization and centralization.

Decentralization refers to the capacity of the internet to disperse power and influence to many more people. In the political context, this has (arguably) enabled greater citizen activism. In business, online advertising enables start-ups to get going without relying on venture capitalist funding. Individuals have greater capacity for personal expression now that they can bypass publishing power houses and distribute their own work at virtually no cost. Corresponding to these benefits are a number of negative impacts.
The same technology that allows pro-democracy groups to come together also enables terrorists and pedophile groups to organize and perpetrate harm on a greater scale.

Technology also allows for increasing centralization. The Internet provides a place for the world's information to be easily organized and accessed. But with this comes the risk that certain groups (particularly authoritarian governments) could deliberately misinform citizens.  

Kim raised a number of dilemmas for discussion, including:

• How should technology companies respond to requests from governments to hand over data?
• How should Internet companies respond to different countries' understanding of what content is acceptable? Google's policy to date has been to allow different access in different countries but it has stopped short of allowing any one country to dictate what others countries see.

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.

Ken Banks, the founder of kiwanja.net, spoke about the importance of technology solutions that meet the needs of those working in the developing world and his own work in this area through FrontlineSMS.

While current excitement in the technology world may be focused on increasing centralization through cloud computing, this means little to people working in the developing world where internet connectivity is unavailable or unreliable.  Too little investment is going into building tools that will genuinely assist the work many non-profits are doing now.

Ken developed FrontlineSMS to tap into the potential of mobile phones, which are now widely available and used in the developing world. This is a two way communication system that can be used anywhere where there is a mobile phone signal.  FrontlineSMS is available as a free download and Ken's approach has been not to dictate implementation but rather to allow people to use this very general tool in whatever ways meet their particular needs. This has resulted in diverse applications, for example:

• Monitoring election practices in Nigeria in 2007
• Sending security alerts to humanitarian workers in conflict areas of Afghanistan
• Encouraging young people to take part in elections in Azerbaijan
• Updating local people on the location of speeches during President Obama's visit to Ghana

There is also great potential to combine FrontlineSMS with traditional media, such as radio, that is already widespread throughout Africa, to make this much more interactive.

Ken offered a number of points of guidance for those thinking about designing technology with social applications:

• Work with the equipment that people already have at their disposal
• Make equipment easy to assemble and intuitive
• Price it at a level people can afford
• Think about how use can be replicated - how will other NGOs find out about it?
• Assume a situation of no internet connectivity
• Where possible, give users an ability to connect with others - for example through a forum (this has been particularly successful at FrontlineSMS, with a third of those who download the software joining the online community)
• Don't let a social science approach dominate - it is much better to think in a multi-disciplinary way
• Use technology that is appropriate to the context - don't bring in tools that require knowledge and equipment not already held in the community
• Collaborate, don't compete. Sometimes NGOs can rush to do the same things; examples of genuine cooperation are hard to find

Looking ahead, Ken will be developing functionality for FrontlineSMS that makes use of internet connectivity where this is available. He is also working on finding additional funding to help organizations pay for text messages.

Matt Halprin is a Partner leading Omidyar Network's Media and Stephen King is the Director of Investments and is based in London. They introduced us to the work of Omidyar Network which invests in market-based efforts to give people the technology tools they need to improve their lives.

The network was set up in 2004 by Pierre Omidyar, founder of eBay, and his wife Pam.  It comprises both a venture capital fund and a grant-making foundation.  The network has a strong focus on individual empowerment and is committed to market-based solutions, believing that business is one of the best mechanisms for achieving sustainable social impact. Omidyar looks to invest in projects that have potential to impact large numbers of people and that show signs of real innovation - for example, new business models or new markets.

So far $307 million has been committed, with $138 million going to for-profit investments and $169 million to non-profit grants. There are two broad areas of focus:

• Access to capital: This encompasses projects around microfinance, entrepreneurship and property rights.
• Media, markets and transparence: This encompasses projects around social media, marketplaces and government transparency. Omidyar are particularly interested in the role of journalism in ensuring accountability of governments.

Projects in the Unities States include:

• The Sunlight Foundation - works to make information about Congress and Federal government more accessible and meaningful to citizens; created the first searchable site for all federal government contracts to monitor where money is going.
• Global Integrity - uses quantitative and qualitative analysis to provide a scorecard tracking governance and corruption in different countries.

In the developing world, Omidyar looks to supports access to greater information and government transparency, which it views as key drivers of prosperity. The network is supporting global organizations, national partners in three African countries (Nigeria, Ghana and Kenya) and is establishing a pan-African mechanism for smaller grants. Current global projects include:

• Ushahidi - an open source platform to report and share data in the aftermath of a crisis. Omidyar will be working to help Ushahidi to build traffic to the site and to tackle the challenge of verifying reports.
• Infonet - a web portal that acts as an information hub for all national and devolved budgets in Kenya; currently used by NGOs, citizen groups and the media.
• Mzalendo - a one stop shop for citizens to track the activities of parliamentarians in Kenya.
• FrontlineSMS - a two way communication tool using laptops and mobile phones for organizations without internet access.
