Abstract
Improving the productivity of small farmers is essential for economic development in most poor countries.  Providing access to timely and relevant information could improve the opportunities available to farmers.  However, there are significant challenges related to literacy, infrastructure, access to technology and social, cultural, institutional and linguistic gaps between producers and consumers of knowledge.  The increased adoption of mobile phones is rapidly reducing the physical barriers of access.  Providing voice-based services via low-cost handsets could empower farmers to become producers as well as consumers of knowledge.  In this talk, I discuss several applications my students and I are developing to explore this potential.  Avaaj Otalo (Gujarati for "voice stoop") is the voice-based equivalent of an online discussion board. Farmers and agricultural experts call a toll-free line to ask questions, provide answers, and listen to each others questions, answers and experiences.  We conducted a six-month trial deployment of Avaaj Otalo with fifty farmers in Gujarat, India. Farmers found it useful to learn both from experts and other farmers, sharing advice on many topics - including the best time to sow fodder, recipes for organic pesticides, and homemade devices to scare away wild pigs at night. Digital ICS allows coffee cooperatives to monitor quality and organic certification requirements, and to be more responsive to farmers' needs.  Field inspectors use mobile phones to document growing conditions and record farmers questions and comments through a combination of text, audio and images.  In a six-month trial deployment, the system significantly reduced operational costs, saving the cooperative approximately $10,000 a year.  The cooperative also obtained richer feedback from its members, which can be used for targeting extension, improving decision-making and reaching out to consumers.  In both of these systems, voice provides not only an accessible interface to information, but a medium for aggregating and representing knowledge itself.  We found this approach more suitable for engaging communities more comfortable with oral forms of communication, for whom text and structured data represent significant barriers to expression.  Most importantly, we have found that rural communities have a deep desire to be "heard", and simply need the tools required to define and achieve "development" on their own terms.

Tapan Parikh's research focuses on the use of computing to support sustainable economic development across the World. I want to learn how to build appropriate, affordable information systems; systems that are accessible to end users, support learning and reinforce community efforts towards empowerment, economic development and sustainable use of natural resources. Some specific topics that I am interested in include human-computer interaction (HCI), mobile computing and information systems supporting microfinance, smallholder agriculture and global health

Summary of the Seminar
Tapan Parikh, of UC Berkeley School of Information, spoke about a number of projects that are using mobile phone based technology to give small businesses the information they need to improve productivity. He argued that voice technology has distinct advantages over text, because it overcomes challenges of illiteracy while responding to a strong need people feel to be heard.

Abstract
The federal Endangered Species Act (ESA) and California's Endangered Species Act (CESA) aim to protect species from extinction by restricting property development on the habitats of imperiled species. Proponents of these laws argue that the development restrictions are necessary in order to protect valued species, whereas opponents argue that the burden is too restrictive. The controversy surrounding species protection is especially intense in California, where many species are subject to protection and where developmental pressures are particularly acute.

This paper provides estimates of the impacts on housing supply in California due to protection of animal species provided under the ESA and CESA. Specifically, the paper estimates the effect on housing development in California census tracts that contain protected endangered animals. The main empirical complication in addressing this research question is that census tracts that contain one or more protected species are likely different from census tracts that do not contain such species. Further, these differences could also contribute to differences in housing supply, therefore biasing the estimated effects. We attempt to address this concern using a unique research design and data set. We find that a census tract that has an endangered animal listed by the federal or state government in the 1990s does not have a subsequent reduction in the development of housing units. This suggests that species protection in California does not impede housing supply.
