This assessment provides input to the reauthorized National Integrated Drought Information System (NIDIS) and the National Climate Assessment (NCA), and it establishes the scientific foundation needed to manage for drought resilience and adaptation. Focal areas include drought characterization; drought impacts on forest processes and disturbances such as insect outbreaks and wildfire; and consequences for forest and rangeland values. Drought can be a severe natural disaster with substantial social and economic consequences. Drought becomes most obvious when large-scale changes are observed; however, even moderate drought can have long-lasting impacts on the structure and function of forests and rangelands without these obvious large-scale changes. Large, stand-level impacts of drought are already underway in the West, but all U.S. forests are vulnerable to drought. Drought-associated forest disturbances are expected to increase with climatic change. Management actions can either mitigate or exacerbate the effects of drought. A first principal for increasing resilience and adaptation is to avoid management actions that exacerbate the effects of current or future drought. Options to mitigate drought include altering structural or functional components of vegetation, minimizing drought-mediated disturbance such as wildfire or insect outbreaks, and managing for reliable flow of water.

Issues of water quality and scarcity are of great concern across the U.S. Caribbean. In recent years Puerto Rico and the U.S. Virgin Islands have experienced uncommonly dry weather that has caused moderate to severe droughts. In 2014-2015, severe drought in Puerto Rico required the implementation of water restrictions that affected millions of people. The summer of 2015 was the third driest period in Puerto Rico since 1898, forcing the strictest water rationing in its history. Emerging climate models for the region (Figure 1) predict an overall decrease in precipitation over the next century, but also to greater variance in seasonality and an increase in intense precipitation events. The temporal and spatial distribution of rainfall can have profound effects on the hydrology as well as the phenology and life-cycle of trees, rangeland species, pests and pollinators. Changing rainfall patterns will mean major adjustments in how working lands are managed by producers and planners.

"Most regions of the United States are projected to experience a higher frequency of severe droughts and longer dry periods as a result of a warming climate. Even if current drought regimes remain unchanged, higher temperatures will interact with drought to exacerbate moisture limitation and water stress. Observations of regional-scale drought impacts and expectations of more frequent and severe droughts prompted a recent state-of-science synthesis (Vose et al. 2016). The current volume builds on that synthesis and provides region-specific management options for increasing resilience to drought for Alaska and Pacific Northwest, California, Hawai'i and U.S.-Affiliated Pacific Islands, Interior West, Great Plains, Northeast and Midwest, and Southeast."--

Of the many climate events that threaten agricultural production in the region, increasing drought is one of the most devastating. The agricultural sector is typically the first to feel the impacts of drought, since the majority of crops in the U.S. Caribbean are rainfed. Drought conditions can quickly lead to reduced crop yield, desiccation, and crop losses island-wide, unlike other hazards such as floods and landslides that occur on a much smaller scale. As the climate changes, droughts in the U.S. Caribbean are projected to become more frequent and intense. Implementing the use of cover crops, water retention ponds, and drought tolerant varieties can help reduce the impacts of drought.

This book explains how to foresee and manage ecosystem changes in the Luquillo Mountains in Puerto Rico, by looking at underlying causes and effects. The lessons from the abiotic and biotic environments, populations, and ecosystems in this region apply to analogous forest biomes in Central and South America, as well as around the world.
