Is it possible to combine modern tropical agriculture with environmental conservation? Brazilian agriculture offers encouraging examples that achieve high production together with adequate environmental protection. However, these effective practices may soon lose ground to the conventional custom of resource overexploitation and environmental degradation.

A revision to the Forest Act, the main Brazilian environmental legislation on private land, has just been submitted to Congress, and there is a strong chance that it will be approved. The proposed revision raises serious concerns in the Brazilian scientific community, which was largely ignored during its elaboration. The new rules will benefit sectors that depend on expanding frontiers by clear-cutting forests and savannas and will reduce mandatory restoration of native vegetation illegally cleared since 1965. If approved, CO2 emissions may increase substantially, instead of being reduced as was recently pledged in Copenhagen. Simple species-area relationship analyses also project the extinction of more than 100,000 species, a massive loss that will invalidate any commitment to biodiversity conservation. Proponents of the new law, with well-known ties to specific agribusiness groups, claim an alleged shortage of land for agricultural expansion, and accuse the current legislation of being overprotective of the environment in response to foreign interests fronted by green nongovernmental organizations. However, recent studies show that, without further conversion of natural vegetation, crop production can be increased by converting suitable pastures to agriculture and intensifying livestock production on the remaining pasture. Brazil has a high potential for achieving sustainable development and thereby conserving its unique biological heritage. Although opposed by the Ministry of the Environment and most scientists, the combination of traditional politicians, opportunistic economic groups, and powerful landowners may be hard to resist. The situation is delicate and serious. Under the new Forest Act, Brazil risks suffering its worst environmental setback in half a century, with critical and irreversible consequences beyond its borders.

This Spring quarter, while our seminar series took a break, Terry Winograd and Joshua Cohen taught a new course at the Hasso Plattner Institute of Design (the d.school): Designing Liberation Technologies.

During this class, small interdisciplinary teams focus on a term-long design project, taking advantage of the design process structures and methods that have been developed in the d.school. This year's course developed as a collaboration between Stanford, the University of Nairobi and Nokia Africa Research Center.  The focus area was finding ICT solutions to the healthcare needs of people living in Kibera slum outside Nairobi.

Under the guidance of Jussi Impiö at Nokia and the Computer Science faculty, 27 students from the University of Nairobi Computer Science department conducted need finding studies at a number of health-related sites, including clinics, hospitals, community health workers, community leaders, and government offices. They read background materials, made observations, and talked with a wide variety of stakeholders. Their reports became the basis of the Stanford teams' initial understanding of users and needs. Communication with the group in Nairobi was also maintained throughout the course, using a Facebook group to facilitate discussions, as well as several teleconference sessions.

Working in small teams, 20 Stanford students from a wide range of disciplines worked over 10 weeks to develop initial design concepts to respond to some of the needs that had been identified. Click on the title of each project to view their final presentations:

  • mNote: an online archive for community health worker notes. This application empowers community health workers by preserving the flexibility and control they appreciate in their current paper notebooks, but adding digital knowledge management capabilities.
  • M-MAJI ("mobile water"): an electronic information system that allows people to use their mobile phones to identify clean water sources in their community. The application seeks to decrease the time and money spent searching for water, improve water quality, and foster vendor accountability by providing a mechanism for user feedback.
  • Babybank: a dedicated savings plan designed specifically for pregnant women in the slums of Nairobi. By leveraging a popular cell phone payment system, M-Pesa, the application aims to make savings easier, so that expecting mothers can afford the services that will keep themselves and their babies healthy.
  • Mazanick: an application to provide support and advice to pregnant women via SMS, with the aim of helping motivate them to attend prenatal appointments.
  • PillCheck (Kifaa cha Tenbe): a mobile application to help people in Kibera find information on the availability and pricing of malaria drugs quickly.
  • PatientMap :a system to make the waiting process in clinics more transparent, and to increase patient trust in the medical system.

This summer, two follow up trips are planned, with Nairobi students due to spend several weeks at Stanford, while a number of students from the Stanford group will visit Nairobi to explore possibilities for developing their projects further. Building on the success and lessons learnt so far, the Designing Liberation Technologies course will be open to a new set of students next academic year.

Participants at "China 2.0: The Rise of a Digital Superpower (May 2010)" discussed China's rapid developments in online areas like e-commerce, television, music and games, how its infrastructure and financing would handle this exploding growth, as well as how global firms can thrive in this landscape.

The two-day workshop brought together executives and entrepreneurs from China and overseas to explore the ramifications of a community of 400 million online and 750 million mobile consumers, one with constantly-spawning innovative start-ups and established multi-billion dollar enterprises in social networking, games, video, music and e-commerce.

The conference was covered by KGO-TV's David Louie (Silicon Valley hoping to cash in on wireless in China) and in Chinese by the World Journal (史大论坛 探讨中国网络发展及影响).

We are pleased to be able to announce that the Program on Liberation Technology will have two new visiting scholars from September 2010 - Patrick Meier and Evgeny Morozov.

Patrick Meier is a fourth-year PhD Candidate at The Fletcher School of Law & Diplomacy and Co-Director of the Program on Crisis Mapping and Early Warning at the Harvard Humanitarian Initiative. His dissertation research analyzes the impact of the information revolution on the balance of power between repressive rule and civil resistance. He is particularly interested in how repressive regimes and resistance groups use information communication technologies to further their own strategic and tactical goals. Patrick serves as Director of Crisis Mapping and Strategic Partnerships at Ushahidi and co-founded the International Network of Crisis Mappers. He is also on the Board of Advisors of  DigiActive and Digital Democracy, two leading digital activism and democracy initiatives. Patrick blogs at iRevolution and Early Warning.

Evgeny Morozov is a leading thinker and commentator on the political impact of the Internet and a well known opponent of internet utopianism.  He is a contributing editor to Foreign Policy and runs the magazine's Net Effect blog about the Internet's impact on global politics. Evgeny is currently a Yahoo! fellow at the Institute for the Study of Diplomacy at Georgetown University. Prior to his appointment to Georgetown, he was a fellow at the Open Society Institute, where he remains on the board of the Information Program. Before moving to the US, Evgeny was based in Berlin and Prague, where he was Director of New Media at Transitions Online, a media development NGO active in 29 countries of the former Soviet bloc. He is writing a book about the Internet and democracy, to be published this fall by PublicAffairs.

We are looking forward to welcoming Patrick and Evgeny to the Stanford community in a few months time.

As efforts to mitigate climate change increase, there is a need to identify cost-effective ways to avoid emissions of greenhouse gases (GHGs). Agriculture is rightly recognized as a source of considerable emissions, with concomitant opportunities for mitigation. Although future agricultural productivity is critical, as it will shape emissions from conversion of native landscapes to food and biofuel crops, investment in agricultural research is rarely mentioned as a mitigation strategy. Here we estimate the net effect on GHG emissions of historical agricultural intensification between 1961 and 2005. We find that while emissions from factors such as fertilizer production and application have increased, the net effect of higher yields has avoided emissions of up to 161 gigatons of carbon (GtC) (590 GtCO2e) since 1961. We estimate that each dollar invested in agricultural yields has resulted in 68 fewer kgC (249 kgCO2e) emissions relative to 1961 technology ($14.74/tC, or ~$4/tCO2e), avoiding 3.6 GtC (13.1 GtCO2e) per year. Our analysis indicates that investment in yield improvements compares favorably with other commonly proposed mitigation strategies. Further yield improvements should therefore be prominent among efforts to reduce future GHG emissions.

California is like many states whose electricity customers are still protected by real-time price risk through fixed retail price.  This fixed retail price, however, restricts the consumer's ability to save money by reducing consumption during peak hours. 

Those queasy about allowing or subjecting customers' to dynamic pricing are up for a fight; major technological barriers to dynamic pricing will soon be eliminated as all three of California's IOUs will have interval meters.  The Home Area Network segment of the Smart Grid Ecosystem Broadband Plan includes some strong words for State PUCs, urging them to in turn push utilities to deliver real time pricing data to consumers.  What remains to be seem is: What set of pricing plans would satisfy both HAN vendors and the PUCs?

Panel discussion topics:

  • Is some dynamic pricing available?
  • What will the plans look like?
  • Research questions
  • What set of pricing plans would satisfy both HAN vendors and the PUCs?

Effectively addressing emissions from deforestation will require both an international policy - to address the global nature of the climate problem, and domestic policies - to effectively respond to the international policies and take unilateral action; Suzi will be focusing on the former. 

The key challenges in reducing emissions from deforestation and degradation (REDD) policy are monitoring, permanence, and additionality - leakage and adverse selection as well as the risks involved if REDD is linked explicitly to international carbon markets.  They propose an international system based on national baselines, temporary rewards for protection and externally replicable monitoring and illustrate the potential outcomes in terms of  additional carbon storage, the cost of emissions reductions, and transfers of resources between countries.  Suzi will also briefly discuss how national governments might respond to an international policy of this type.

The Chinese health care system has experienced profound changes like retrenchment of state financial support in the past decades. These changes have prompted the Chinese media and some academics to suggest that patients have a relatively low level of trust in physicians in today's China. In this colloquium, Dr. Tam reports the results of his survey of patient trust in physicians in Beijing's public hospitals. The survey was conducted by Horizon Research Group between November 2009 and January 2010, and 434 patients were interviewed.
 
The survey asked the respondents their degree of trust regarding the following three dimensions: physician agency, competence, and information provision. The survey finds a relatively high level of patient trust in physicians in Beijing public hospitals. Additionally, the survey data highlight three major determinants of patient trust in physicians, namely exposure to negative media reports about physicians and hospitals; the patient's self-assessed health status; and the patient’s level of education and income.
 
Waikeung Tam received his Ph.D. in political science at the University of Chicago in 2009. He is currently a Research Fellow at the LKY School of Public Policy at the National University of Singapore. His research focuses on public policy, political development, law and society, with special reference to China and Hong Kong. His research has been published in China Review, Asian Perspective, Journal of Contemporary Asia, and Law & Social Inquiry.
