Open Access Publications from the University of California


The UCSD Sustainability Solutions Institute turns knowledge and technology into solutions. Created by Chancellor Fox in January 2009, building o recent cross-campus initiatives and long-standing academic and research programs such as the UCSD Environment and Sustainability Initiative, SSI services to acquire resources and organize projects to address sustainability challenges. Through SSI, faculty, researchers, students and non-academic partners are tackling the complex questions that society is facing as we strive for economic progress while sustaining the natural systems on which we depend. We do this through collaborations across departments and partnerships that extend beyond campus, working at local, regional, and global scales. These papers are a collection of both ESI and SSI funded research documents.

Venice Sustainability Advisory Panel

The Venice Sustainability Advisory Panel (VSAP), an international group of experts in environmental sustainability put together by UC San Diego’s Sustainability Solutions Institute, was created to advise key authorities and decision-makers on how to prepare regular formal assessments of the environmental sustainability of the Venice Lagoon and its surrounding regions, taking into account the specific social and economic drivers of environmental change in the region. Assessment is regarded as a critical initial step in achieving adaptive management capability. The VSAP met three times - twice in Venice (in June 2008 and September 2008) and once in La Jolla (in January 2009).

The Transition to a Carbon-Neutral Energy Economy: Exploring UCSD's Role

A workshop of UCSD faculty, researchers, and students, joined by representatives of industry, government and non-profit organizations, spent two days considering the role UCSD and its partners could and should play in addressing the challenges of energy and sustainability. As UCSD proceeds with developing a campus-wide Environment and Sustainability Initiative, it is clear that energy must be an important area of research, teaching, and partnership. The workshop succeeded in providing a forum for participants to share their expertise and explore the potential for UCSD to develop interdisciplinary sustainable energy projects. UCSD has a wide range of expertise, including ocean and atmospheric sciences, engineering, informatics, chemistry, biology, health sciences, economics, management, international relations, political science, and urban studies. UCSD is also part of the larger San Diego community, the border region, and has a role to play at the national and international level as well.

Economic Analysis of a 3MW Biomass Gasification Power Plant

An economic and technical analysis of the use of separated wood biomass as a feedstock for gasification for a 3 MW power plant was conducted for the Miramar Landfill, located in San Diego County, CA. The method to generate combustible gas from the biomass is based on a dual-fluidized bed gasification process which operates at atmospheric pressure with air and produces a high quality producer gas with little nitrogen. The objective of the study was to determine the economic feasibility of the proposed biomass power system in terms of the potential revenue streams and costs. Major economic considerations in the analysis include feedstock, capital, and operating costs. Regulatory issues, inclusive of production credits, renewable energy incentives, and feed-in tariffs are addressed as significant economic inputs. The Miramar landfill, in San Diego County, CA is representative of a typical existing urban landfill, with corresponding feedstock and some market for separated wood biomass. The economic analysis of the proposed 3MW gasification power plant indicates that it would not have a net positive NPV under the current urban scenario. More likely successful candidates are landfill sites in more rural areas or urban sites, where new landfills are being developed or where the landfill is no longer operational but has become a transfer station. In all cases waste heat sales are a critical element in determining economic viability.

Metals concentration in salt marshes plants and kelp around San Diego: A window to environment quality

This project was developed into two avenues aiming at assessing levels of metals in kelp and salt marsh plants in the San Diego area. This information was then used to address whether metals levels found in kelp and salt marsh plants reflect bioavailable metals in the environment, which could help their use in environmental monitoring.

Potential impacts of global climate change on Tijuana River Watershed hydrology - An initial analysis

During the past year, an investigation has been initiated regarding how future climate changes may impact the hydrology of the Tijuana River Watershed – a binational watershed. The study has used gridded observed daily precipitation and temperatures and downscaled daily precipitation and temperature projections from three global climate models (GCM) to drive the VIC macroscale hydrologic model. Sensitivity analysis using VIC suggests about 2% reduction of runoff for each 1% reduction in precipitation. A 1oC increase in average temperature produces about 3% reduction of runoff. All three GCM simulations yield annual warming, with end-of-century temperature increases from approximately +1oC under a lower emission scenario in the less responsive PCM1 to +3oC in a higher emission scenario with the more responsive GFDL model. Climate projections suggest greater warming in the spring and summer months ranging between 2oC to 3oC under the higher emission scenario. Two of the three GCM simulations yield more frequent summer drying as gauged by VIC simulated soil moisture in the twenty-first century under the higher emission scenario. Summer soil moisture declines most, and most rapidly, in the later part of the twenty-first century. This initial evaluation provides perhaps the first direct estimates of the climate change impacts on the Tijuana River Watershed. However, transforming these results into a more useable projections and impacts will be a task for the future and will require collaboration and interaction between local stakeholders and the researchers.
