The drylands region shared by the United States and Mexico currently faces multiple sustainability challenges at the intersection of the human and natural systems. Warming and drying conditions threaten surface water and groundwater availability, disrupt land- and marine-based livelihood systems, and challenge the sustainability of human settlements. These biophysical challenges are exacerbated by a highly mobile and dynamic population, volatile economic and policy conditions, increased exposure to extreme events, and urbanization on marginal, vulnerable lands. The U.S. National Academies of Sciences, Engineering, and Medicine collaborated with the Mexican Academy of Sciences, Academy of Engineering, and the National Academy of Medicine to plan a 2-day binational workshop, Advancing Sustainability of U.S.-Mexico Transboundary Drylands. The workshop goals were to highlight the challenges facing the region, assess the scientific and technical capacity that each nation can bring to bear in addressing these challenges, and identify new opportunities for binational research collaboration and coordinated management approaches in the advancement of sustainability science and development. This publication summarizes the presentations and discussions from the workshop.

Drought, a serious global issue, is being aggravated by climate change. Both pedological and agronomic droughts are a major risk factor with adverse effects on agronomic productivity, food and nutritional security, and human wellbeing. This volume in the Advances in Soil Sciences series: Considers processes, factors, and causes of pedological/agronomic droughts. Discusses effects of global warming on soil drought Describes management options to enhance drought resilience of agricultural soils Presents soil moisture management options to mitigate drought Includes information on soil health and its effects on drought Explains innovative options in measurement of soil moisture content

Interdisciplinary volume considers how nine arid/semi-arid river basins with irrigated agriculture will survive future climate change, siltation, and decreased flow.

This collection of papers examines water management in two of the worlds prominent, arid transboundary areas facing similar challenges. In the Middle East, the chronically water-short Israeli-Palestinian region has recognized the need both to conserve and supplement its traditional water sources. Across the globe on the North American continent, A

Volume 1 (A and B) covers international organizations throughout the world, comprising their aims, activities and events.
