SUMMARY:Environmental Studies Seminar Series | Exit Talk: Geospatial Optimization of California's Organic Waste Diversion System: Transportation\, Compliance\, and Infrastructure Planning

California’s Senate Bill 1383 (SB 1383) requires a 75% reduction in organic waste disposal relative to 2014 levels\, creating substantial infrastructure and logistical challenges. This dissertation develops statewide geospatial optimization frameworks linking 447 waste generating jurisdictions\, approximately 200 composting facilities\, agricultural working lands\, and transportation networks. I examine the spatial alignment of waste generation\, processing capacity\, and cropland demand; the effects of alternative compliance structures on costs and greenhouse gas emissions; and the siting of additional composting infrastructure under economic\, logistical\, and regulatory constraints. Results show that strong spatial differences in waste generation\, processing capacity\, transportation\, and compost end use shape system performance and regional burdens. Statewide coordination can reduce costs and emissions by shifting diversion toward lower cost locations\, while jurisdiction level compliance promotes broader participation. Substantial additional processing capacity is still required\, and siting is constrained by transportation\, water and air quality regulation\, and limited VOC Emission Reduction Credit availability. Overall\, effective diversion requires coordinated planning of infrastructure\, compliance\, end use markets\, and environmental regulation. \n  \n

SUMMARY:Environmental Studies Seminar Series | Caring for cultural keystones: Indigenous-led stewardship\, public values\, and tree genomics in a hotter\, drier world
DESCRIPTION:In person and via Zoom (Meeting ID: 978 5545 8946\, Passcode: 454736).  \nIf you are unable to stream the talk live and need to access a recorded version\, please contact Stacy Philpott at sphilpot@ucsc.edu. A UC Santa Cruz email address is required to access the recording. \nHost: Maywa Montenegro \nSpeaker: Diana Macias\, UC Berkeley \nTitle: Caring for cultural keystones: Indigenous-led stewardship\, public values\, and tree genomics in a hotter\, drier world \nAbstract: Pinyon pine nuts are a culturally significant food source for Indigenous communities who have cared for pinyon-juniper woodlands for millennia. However\, colonial land dispossession and federal land management have disrupted these relationships\, while recent droughts\, wildfires\, pests and pathogens have resulted in extensive tree die-off. In the Eastern Sierra of California and Nevada\, differing knowledge systems and unequal institutional power have limited effective co-management between Tribes and federal agencies. My work asks: how do we sustain the local variation and place-based knowledge that make tree persistence possible? I share results from three studies: (1) An Indigenous-led monitoring network tracking tree health and cone production\, priorities identified by Tribal Environmental Departments of the Big Pine Paiute\, Bishop Paiute\, and Washoe Tribes; (2) a regional household survey that examined whether recognition of pinyon–juniper woodlands\, climate change knowledge\, and demographic factors predicted four measures of environmental care; and (3) a genomic data set from across the pinyon pine species complex which revealed the geography of genetic variation and signatures of climate adaptation. Together\, these projects show how ecological monitoring\, public perspectives\, and population genomics can inform the future of pinyon-juniper woodlands and underscore a broader responsibility to support Indigenous-led stewardship. \n  \n  \n

SUMMARY:Environmental Studies Seminar Series |  North Stars of Emancipation: Navigating Movements and Institutions to Change Food Systems
DESCRIPTION:In person and via Zoom (Meeting ID: 978 5545 8946\, Passcode: 454736).  \nIf you are unable to stream the talk live and need to access a recorded version\, please contact Stacy Philpott at sphilpot@ucsc.edu. A UC Santa Cruz email address is required to access the recording. \nHost: Stacy Philpott \nSpeaker: Antonio Roman-Alcala\, CSU East Bay \nTitle: North Stars of Emancipation: Navigating Movements and Institutions to Change Food Systems \nAbstract: In this talk\, Dr. Roman-Alcalá will discuss his new book North Stars of Emancipation: California’s Diverse Food and Farming Movements in Times of Racial Reckoning\, based on his twenty years of engaging such movements as both participant and (more recently) researcher. The book addresses how food movements’ racial politics and change-making strategies have shifted over recent decades\, in response to the interventions of activists and allies\, and in relation to the ever-vexing challenge of working across various kinds of difference. Antonio will present insights from North Stars\, illuminating the origins of right wing populist political strategies in California’s agrarian history\, dynamics of contemporary movement organizing among ecological farmers\, farmworkers\, Indigenous people\, food justice activists\, nonprofit staff\, researchers\, and others\, and suggestions for how to both diversify and strengthen the movement. Addressing social scientific and social movement debates about if and how social movements should seek radical change to society\, and how movements might navigate problematic political and economic systems not set up to serve them\, the talk will introduce the book’s call for a “North Star” approach to political change. Such an approach\, Antonio argues\, can leverage food markets and state policy even while seeking a food system (and world) beyond capitalism and the colonial nation-state. \n  \n  \n
