The Evolution of Cooperation in Multigenerational Social Dilemmas

Project Summary

We conduct experiments in multi-generational social dilemmas in which we examine the transmission of individual behaviors within and among groups of experimental participants. These experiments allow us to observe the cultural evolution of cooperation over time, including the roles of institutions, communication, and social learning. We conduct computerized experiments in a lab at UC Davis as well as online experiments using Mechanical Turk.

Sustainable Viticulture: Practice Adoption and Social Networks

Project Summary

The goal of the study is to understand how local agricultural sustainability programs, also known as "partnerships," in three American Viticultural Associations (Lodi, Napa Valley, San Luis Obispo) influence growers' social networks and adoption of sustainable agriculture practices. The primary research task is a grower survey that asks about practice adoption and program participation; we are also conducting a survey of outreach advisers such as extension advisers and viticultural consultants throughout the state.

Social Networks and Travel Behavior

Project Summary

This projects investigates the role of social networks and social influence in travel behavior. Sustainable transportation programs may benefit from the incorporation of social influence through knowledge sharing, establishment of behavioral norms and peer-to-peer participation recruitment. The next phase of this ongoing research will involve evaluation of social influence as a tool in pilot sustainable transportation programs.

Extension 3.0: Knowledge Networks for Sustainable Agriculture

Project Summary

The overarching goal of this proposal is to understand the structure and dynamics of sustainable agriculture knowledge networks in California. We will analyze these networks using survey methods, cognitive maps, and computational social science. In addition to answering basic research questions, we will develop best management practices for using network concepts in agricultural education and outreach programs.

Climate Change and Agriculture

Project Summary

his project examines agriculture and climate change with a focus on both mitigation and adaptation. In particular, we are looking at the variables that influence farmer and agricultural industry adoption of climate change mitigation and adaptation practices. Multiple factors will affect the adoption and innovation of practices in agriculture for mitigation and adaptation to climate change including information sources, climate change perceptions, policy structures, land management strategies, and economic and market drivers.

Agricultural Nutrient Management Decision-Making

Project Summary

This project focuses on how California farmers make decisions about nutrient management and participate in policies regarding non-point source pollution from agriculture. We are surveying, interviewing and observing farmers and agricultural stakeholderes in the field to understand how real-time change is being made to improve nutrient management.

Adoption of Preventative Plant Disease Management Practices

Project Summary

This project examines farmer decision-making in the context of disease management, including the influences of policy, learning, cooperation, economic factors, and individual characteristics. We are using semi-structured interviews, quantitative surveys, and behavioral experiments to better understand farmer decision-making with respect to the adoption of preventative disease-management practices in wood-canker diseases of grape, pistachio, and almond.

Rangeland Decision Making Survey

Adaptive Rangeland Management

Project Summary
We are exploring the institutional and social factors involved with the adoption and diffusion or innovative grazing practices. This is in collaboration with rangeland ecologists who will use an experimental rangeland to measure changes in ecosystem services under different grazing strategies. Survey data will be collected from California and Wyoming ranchers to understand the factors influencing adaptive decision-making.
