Abstract

The 2018 exceptional drought over the Colorado Plateau motivated unprecedented responses by individuals and organizations. Some of these responses made clear that proactive adaptive measures were fundamental to drought resilience. Climate service organizations (CSOs) supporting and observing these responses realized the utility of a network to share and document successful drought responses. In February 2020, a small group of CSOs and Resource managers (RMs) met to envision the Southwest Drought Learning Network (DLN) to align with other existing efforts, but with the specific goal of enabling peer-to-peer learning to build resilience to future droughts. Since then, the network has grown into 5 organized teams focused on specific aspects of building drought resilience. Team activities include sharing case studies to help others learn from past experiences; hosting monthly drought briefings which introduce drought data and management tools; identifying information needed to support critical management decisions; innovating and sharing new and traditional drought monitoring technologies; and building drought resilience with indigenous communities. The network allows for collaboration and leveraging partner resources and strengths. The DLN website (https://dln.swclimatehub.info/) hosts more information about network teams and activities. This innovative network continues to grow in response to management needs and water scarcity in the region. For the benefit of others who may be considering a similar network and supporting peer-to-peer learning, we document the history, process and lessons learned regarding the Southwest DLN.

Abstract

Agricultural production in the U.S. Midwest is vulnerable to drought, and specialty crop producers are an underserved audience for monitoring information and decision-support tools. We investigate the decision-making needs of apple, grape, and cranberry growers using a participatory process to develop crop-specific decision calendars. The process highlights growers’ decisions and information needs during the winter dormant, growing, harvest, and postharvest seasons. Apple, grape, and cranberry growers tend to be concerned with the effects of short-term drought on current crop quality and quantity, while also considering the long-term drought effect on the health of perennial plants and future years’ production. We find gaps in drought information particularly for tactical and strategic decision-making. We describe the use of decision calendars to identify points of entry for existing drought monitoring resources and tools, and to highlight where additional research and tool development is needed.

Significance Statement

While drought causes agricultural losses in the U.S. Midwest, more is known about the impacts and decision-support needs of commodity row crop growers in the region than those of perennial specialty crop growers. We find opportunities for climate information providers to tailor drought information delivery to perennial fruit growers according to the season, the parameters that are relevant to their decisions, and the timeframe of information needed for operational, tactical, and strategic decision-making.

Abstract

The evolution of a flash drought event, characterized by a period of rapid drought intensification, is assessed using standard drought monitoring datasets and on-the-ground reports obtained via a written survey of agricultural stakeholders after the flash drought occurred. The flash drought impacted agricultural production across a five-state region centered on the Black Hills of South Dakota during the summer of 2016. The survey asked producers to estimate when certain drought impacts, ranging from decreased soil moisture to plant stress and diminished water resources, first occurred on their land. The geographic distribution and timing of the survey responses were compared to the U.S. Drought Monitor and to datasets depicting anomalies in evapotranspiration, precipitation, and soil moisture. Overall, the survey responses showed that this event was a multifaceted drought that caused a variety of impacts across the region. Comparisons of the survey reports to the drought monitoring datasets revealed that the topsoil moisture dataset provided the earliest warning of drought development, but at the expense of a high false alarm rate. Anomalies in evapotranspiration were closely aligned to the survey reports of plant stress and also provided a more focused depiction of where the worst drought conditions were located. This study provides evidence that qualitative reports of drought impacts obtained via written surveys provide valuable information that can be used to assess the accuracy of high-resolution drought monitoring datasets.

Abstract

The U.S. Drought Monitor (USDM), a weekly map depicting severity and spatial extent of drought, is used to communicate about drought in state and federal decision-making, and as a trigger in response policies, including the distribution of hundreds of millions of dollars for agricultural financial relief in the United States annually. An accompanying classification table helps interpret the map and includes a column of possible impacts associated with each level of drought severity. However, the column describing potential drought impacts is generalized for the entire United States. To provide more geographically specific interpretation of drought, state and regionally specific drought impact classification tables were developed by linking impacts chronicled in the Drought Impact Reporter (DIR) to USDM severity levels across the United States and Puerto Rico and identifying recurrent themes at each level. After creating state-level tables of impacts observed for each level of drought, a nationwide survey was administered to drought experts and decision-makers (n = 89), including the USDM authors, to understand whether the tables provided accurate descriptions of drought impacts in their state. Seventy-six percent of respondents indicated the state table was an acceptable or good characterization of drought impacts for their respective state. This classification scheme was created with a reproducible qualitative methodology that used past observations to identify themes in drought impacts across multiple sectors to concisely describe expected impacts at different levels of drought in each state.

Abstract

Although agricultural production faces chronic stress associated with extreme precipitation events, high temperatures, drought, and shifts in climate conditions, adoption of climate information into agricultural decision making has been relatively limited. Agricultural advisors have been shown to play important roles as information intermediaries between scientists and farmers, brokering, translating, and adding value to agronomic and economic information of use in agricultural management decision making. Yet little is known about the readiness of different types of agricultural advisors to use weather and climate information to help their clients manage risk under increasing climate uncertainty. More than 1700 agricultural advisors in four midwestern states (Nebraska, Indiana, Iowa, and Michigan) completed a web-based survey during the spring of 2012 about their use of weather and climate information, public or private sector employment, and roles as information intermediaries in three advising specializations: agronomic, conservation, and financial. Key findings reveal that advisors who specialize in providing agronomic information are positively inclined toward acting as weather and climate information intermediaries, based on influence and willingness to use climate information in providing many types of operational and tactical advice. Advisors who provide conservation advice appear to be considering weather and climate information when providing tactical and strategic land-use advice, but advisors who provide financial advice seem less inclined to act as climate information intermediaries. These findings highlight opportunities to increase the capacity of different types of advisors to enable them to be effective weather and climate information intermediaries.

Abstract

Flash droughts, characterized by their unusually rapid intensification, have garnered increasing attention within the weather, climate, agriculture, and ecological communities in recent years due to their large environmental and socioeconomic impacts. Because flash droughts intensify quickly, they require different early warning capabilities and management approaches than are typically used for slower-developing “conventional” droughts. In this essay, we describe an integrated research-and-applications agenda that emphasizes the need to reconceptualize our understanding of flash drought within existing drought early warning systems by focusing on opportunities to improve monitoring and prediction. We illustrate the need for engagement among physical scientists, social scientists, operational monitoring and forecast centers, practitioners, and policy-makers to inform how they view, monitor, predict, plan for, and respond to flash drought. We discuss five related topics that together constitute the pillars of a robust flash drought early warning system, including the development of 1) a physically based identification framework, 2) comprehensive drought monitoring capabilities, and 3) improved prediction over various time scales that together 4) aid impact assessments and 5) guide decision-making and policy. We provide specific recommendations to illustrate how this fivefold approach could be used to enhance decision-making capabilities of practitioners, develop new areas of research, and provide guidance to policy-makers attempting to account for flash drought in drought preparedness and response plans.

Abstract

The pathways between climate information producers and agricultural decision-makers are evolving and becoming more complex, with information increasingly flowing through both public and for-profit intermediaries and organizations. This study characterizes the various channels of climate information flow, as well as the needs and preferences of information intermediaries and end users. We use data from a 2016 survey of farmers and agricultural advisors in 12 U.S. Corn Belt states to evaluate perceptions of climate information and its usability. Our findings reinforce the view that much weather and climate information is not reaching farmers explicitly but also suggest that farmers may not be aware of the extent to which the information is packaged with seed, input, or management recommendations. For farmers who are using weather and climate information, private services such as subscription and free tools and applications (apps) are as influential as publicly provided services. On the other hand, we find that agricultural advisors are engaged users and transformers of both public and private sources of weather/climate information and that they choose sources of information based on qualities of salience and credibility. Our results suggest that climate information providers could improve the use of information in agriculture by engaging advisors and farmers as key stakeholders and by strategically employing multiple delivery pathways through the private and public sectors.
