2 AGI Critical Issues Forum: Regional Groundwater Resources Foreword

he American Geosciences Institute (AGI) represents and serves the geosci- ence community by providing collaborative leadership and information to Tconnect Earth, science, and people. We created the Critical Issues Forum series as a platform to reach a broader audience of decision makers, including those at the regional, state, and local levels, and to improve public understanding and perception of the geosciences. I am pleased to present this report summarizing the stimulating presentations and discussions from the second AGI Critical Issues Forum, Addressing Regional Groundwater Resources: Lessons from the High Plains Aquifer. Much has been written about the High Plains Aquifer, due to its critical importance as the major source of groundwater for irrigation in the High Plains region of the United States. This aquifer spans eight states and supports the people and livelihood of region, while also maintaining an agricultural base that is responsible for nearly $35 billion in crops annually. The two-day meeting facilitated lively discussion on common groundwater challenges, resource management approaches, and communication strategies in the High Plains Aquifer region. The forum presentations and dialogue focused on two major questions: • How have experts and stakeholders in High Plains Aquifer (HPA) states addressed depletion of regional groundwater resources? • Are there lessons learned or best practices from the HPA and/or other aquifers? On behalf of AGI and the broader geoscientific community, I extend my sincere thanks to all who participated in the Forum and look forward to hosting other vital conversations highlighting issues that are critical to geoscience and society. Sincere regards,

Allyson Anderson Book Executive Director, American Geosciences Institute

On the ground, these geometric patchworks are clustered fields of farmland and pasture that both provide a living for many of the people who call these regions home and feed much of the country. These verdant patches are made possible mainly by the presence of groundwater, the lifeblood of irrigation systems in the High Plains region.

28 AGI Critical Issues Forum: Regional Groundwater Resources About the American Geosciences Institute (AGI)

he American Geosciences Institute represents and serves the geoscience Tcommunity by providing collaborative leadership and information to connect Earth, science, and people. AGI was founded in 1948, under a directive of the National Academy of Sciences, as a network of associations representing geoscientists with a diverse array of skills and knowledge of our planet. The Institute provides information services to geoscientists, serves as a voice of shared interests in our profession, plays a major role in strengthening geoscience education, and strives to increase public awareness of the vital role the geosciences play in society’s use of resources, resilience to natural hazards, and the health of the environment. AGI connects Earth, science, and people by serving as a unifying force for the geoscience community. With a network of 51 member societies, AGI represents more than a quarter-million geoscientists. No matter your individual discipline, AGI’s essential programs and services will strengthen your connection to the geosciences.
