The Essential Role of Local Context in Shaping Risk and Risk Reduction Strategies for Snowmelt-Dependent Irrigated Agriculture
2024
Earth's Future, Volume12, Issue 6, e2024EF004577
Gordon, B.L., Boisrame, G.F.S., Carroll, R.W.H., Ajami, N.K., Leonard, B., Albano, C., Mizukami, N., Andrade, M.A., Koebele, E., Taylor, M.H., and Harpold, AA
Even as some supply-side adaptations diminish, we show that many local areas could manage risk by implementing routine changes in demand. This is particularly true for areas in the intermountain west...
