H078:
Irrigation using Groundwater and its Effects on Aquifers, Nutrient Cycling, and Food Security





Session ID#: 23543

Session Description:
Irrigated agriculture supports 40% of the global food supply on 20% of the agricultural land.  In the US, groundwater used for irrigation makes up nearly 1/5 of all freshwater withdrawals.  Reliance on groundwater for irrigation is expected to grow due to agricultural expansion and intensification in the face of rising temperatures, rainfall variability, food demand and decreasing surface water availability.  To sustainably manage groundwater resources while increasing food production, we need an interdisciplinary understanding of irrigation using groundwater, including its drivers, feedbacks, and externalities.  We invite biophysical and social science submissions that address topics related to irrigation using groundwater at any scale including, but not limited to, groundwater depletion, remote sensing and other quantification methods, trends in irrigation, soil nutrient cycling including net carbon balances, climate feedbacks, food security, human behavior, and water management policies including transboundary aquifers.
