Climate change is projected to dramatically impact agricultural production across the world. Agricultural producers must adapt to changing conditions by implementing practices and utilizing knowledge that creates resilient operations. This study explores how Montana farmers and ranchers use of different types of knowledge during periods of drought and how risk perceptions and trust influence the use of knowledge. To understand the role trust and risk in producers’ use of local knowledge and climate information, I conducted five focus groups with 34 Montana agricultural producers. Producers explained that they encounter many agriculture-related risks, including uncertain forecasts, financial losses, and adverse weather. …

Drought stress is a major contributing factor to adult tree mortality and limits regeneration across the globe. Drought effects are often studied on a site level, but recent advances in remote sensing allow for observations of plant water status across broader geographic scales. The vegetation optical depth (VOD) derived from satellite sensor microwave backscatter has been shown to be sensitive to canopy water content, and can therefore provide useful information on how plant water status changes over time. We develop an index which quantifies the normalized difference between diurnal VOD retrievals (nVOD) across the western U.S. to determine where plant …
