ABSTRACT

Water storage infrastructure is an indispensable part of many water supply systems, and its importance is experiencing a resurgence due to the increasing water irregularity induced by climate change and ever-growing water demand. Leveraging the commission of Hushan Reservoir in Taiwan as a quasi-experiment, this study provides some of the first causal evidence of the economic benefits of a reservoir from housing market and crop production for guiding sustainable water management. Using the administrative property transaction data and a spatial difference-in-differences framework, we find that the commission of Hushan Reservoir increases the values of residential property and farmlands by 4.1 and 8.9 %, respectively. We also find that enhanced irrigation water availability increases rice yield by over 4 % but has no impact on planted areas. Despite expectations of reduced groundwater use, our results show no evidence of a rebound in groundwater levels in the four years following the commission of the reservoir.

ABSTRACT

This study investigates how exposure to riskier environments influences risky road behaviors, using the COVID-19 pandemic as a natural experiment. Utilizing administrative individual traffic violation records from Taipei, where neither mandatory lockdown nor mobility restrictions were imposed, we find that pandemic-induced risk decreased speeding violations and that the effect was transitory. However, no significant changes were observed concerning violations with a minimal risk of casualties, such as illegal parking. These findings suggest that experiencing a higher level of life-threatening risk discourages risky behaviors concerning human life but has little spillover effect on those concerning only financial costs.

ABSTRACT

Firescapes of the Mid-Atlantic are understudied compared to other ecosystems in the United States, and little is known about the acceptance of prescribed fire as a forest management tool. Yet, this region harbors high levels of wildland-urban interface (WUI), has a close intermingling of land ownerships, and reflects substantial regional heterogeneity in burning histories and fire hazards. As prescribed fire is increasingly applied in the Mid-Atlantic as a critical tool to meet various land management objectives, research is needed to help managers understand community perceptions of prescribed fire implementation. Through intercept surveys of forest recreationists and online surveys of fire managers, this study investigates perceptions about prescribed fire use in the Mid-Atlantic, in addition to the critical contributing factors of public support toward prescribed fires. Two states, Pennsylvania and New Jersey, were selected as case studies to explore regional differences in social perception due to their contrasts in fire history, policy, management objectives, and social exposure. Our results show moderate social awareness of local prescribed fires, moderate to high familiarity with prescribed burning, high agency trust, and strong community support toward prescribed fires. However, the perceived concerns and benefits differed between managers and forest recreationists and between recreationists from Pennsylvania and New Jersey. The factors influencing the support of prescribed burning practices included forest management beliefs, concern about prescribed fire effects, familiarity with prescribed fires as a forest management tool, and awareness of local prescribed fires. Collectively, these results highlighted needs in public outreach to strengthen education, build broader community awareness, engage critical stakeholder groups such as forest recreationists, and re-align public outreach messages based on community-level concerns and perceived benefits. Additionally, it will be vital for the scientific community to help monitor critical shifts in forest value orientations and fill in significant research gaps regarding prescribed fire benefits.

ABSTRACT

INTRODUCTION: Many diabetes education programs address the problem of diabetes, but little attention is given to the economic impact of such programs. Our objective was to assess the effectiveness of a community-based education program in improving diabetes-related lifestyle behaviors and biomarkers and ascertain the economic benefits of the program for adults aged 18 years or older with type 2 diabetes, prediabetes, or no diagnosis of diabetes in Pennsylvania. METHODS: From October 2012 through June 2015, Pennsylvania State University Extension's Dining with Diabetes program collected data on 2,738 adults with type 2 diabetes or prediabetes and adult family members without diabetes. The program consisted of 4 weekly 2-hour classes and a follow-up class conducted 3 months after the fourth 2-hour class. In the initial class and the follow-up class, participants completed a lifestyle questionnaire and their hemoglobin A1c and blood pressure were measured. Economic benefit was calculated as the medical expenditure cost savings resulting from program participation. RESULTS: At 3-month follow-up, a significant number of participants had improved their lifestyle behaviors (diet and physical activity), had reductions in hemoglobin A1c and blood pressure, and improved their diabetes status. The Dining with Diabetes program had a 5-year benefit-cost ratio of 2.49 to 3.35. CONCLUSION: Participants who completed the Dining with Diabetes program had significant improvements in diabetes-related biomarkers and lifestyle behaviors. If the Dining with Diabetes program were extended to half of the 1.3 million people living with diabetes in Pennsylvania and if they had similar improvements, the 1-year benefit to the state would be approximately $195 million, assuming a conservative 15% decrease in direct medical costs.
