THE OVERALL GOAL OF THE KARUK AGROECOSYSTEM RESILIENCE INITIATIVE, LED BY THE UNIVERSITY OF CALIFORNIA AT BERKELEY AND THE KARUK TRIBE, IS TO ENHANCE THE RESILIENCE OF CULTURAL AGROECOSYSTEMS UNDER VARIABLE CLIMATIC CONDITIONS WITHIN THE KARUK ABORIGINAL TERRITORY IN THE KLAMATH RIVER BASIN. THROUGH INTEGRATED RESEARCH AND EXTENSION, WE AIM TO 1) ASSESS THE CONDITION OF CULTURAL AGROECOSYSTEMS AND COMPONENT CULTURAL FOODS AND FIBERS TO UNDERSTAND HOW LAND USE, LAND MANAGEMENT, AND CLIMATE VARIABLES HAVE RESULTED IN AGROECOSYSTEM RESILIENCE OR VULNERABILITIES, 2) DEVELOP INNOVATIVE DECISION MAKING TOOLS THROUGH COMMUNITY-BASED PLANNING PROCESSES THAT CAN IMPROVE LAND MANAGEMENT DECISION-MAKING AT THE FEDERAL, STATE, TRIBAL AND COMMUNITY LEVELS, AND 3) BUILD CAPACITY OF THE KARUK TRIBE THROUGH WORKSHOPS AND MENTORSHIP IN RESEARCH, ANALYSIS, MAPPING AND VISUALIZATION TECHNIQUES TO ASSESS AND MANAGE FOR ABUNDANT CULTURAL FOOD AND FIBER RESOURCES AND OVERALL AGROECOSYSTEM RESILIENCE BEYONDTHE GRANT.THIS PROJECT ADDRESSES THE PROGRAM AREA PRIORITIES BY A) ANALYZING IMPACTS OF CLIMATE VARIABILITY ON BIO-PHYSICAL, SOCIAL, AND INSTITUTIONAL COMPONENTS OF CULTURAL AGROECOSYSTEMS, B) EXAMINING POTENTIAL ADAPTATION AND MITIGATION STRATEGIES THAT CAN MAKE CULTURAL FOOD AND FIBER PRODUCTION MORE RESILIENT AND SUSTAINABLE IN INCREASINGLY VARIABLE CLIMATIC CONDITIONS, D) DESIGN POLICY OPTIONS OR INSTITUTIONAL FRAMEWORKS THAT IMPROVE AGROECOSYSTEM PRODUCTIVITY AND RESILIENCE AND MITIGATE IMPACTS ON HUMAN, ANIMAL, PLANT, AND ENVIRONMENTAL HEALTH AND WELL-BEING, AND FEEDBACKS ON CLIMATE VARIABILITY. OUR APPROACH AND RESULTS MAY SERVE AS A MODEL FOR OTHER TRIBES STRIVING TO REVITALIZE CULTURAL FOODS AND FIBERS, ENHANCE FOOD SECURITY AND ACHIEVE AGROECOLOGICAL RESILIENCE IN THE FACE OF CLIMATE CHANGE.
