Using the case of chronic wasting disease (CWD) in white-tailed deer, we estimated hunters’ willingness-to-pay (WTP) for testing their game and determined how their perception of disease risk, trust, and confidence in wildlife agency affected hunter participation in ongoing disease surveillance. The average WTP for testing was $23.75 per deer, and it was positively related to trust and confidence in the wildlife agency and the perception of risk about deer populations in the declining area and the pathogen spreading to other areas. These findings imply that implementing active outreach programs can improve hunter participation in user-paid systems for CWD surveillance.

While conservation practices promote soil health and reduce the negative environmental effects from agricultural production, their adoption rates are generally low. To facilitate farmer adoption, we carried out a survey to identify potential challenges faced by farmers regarding conservation tillage and cover crop adoption in the western margin of the US Corn Belt. We found farmers' top two concerns regarding conservation tillage were delayed planting, caused by slow soil warming in spring, and increased dependence on herbicide and fungicides. Narrow planting window and lack of time/labor were perceived by farmers as the two primary challenges for cover crop adoption. Some sense of place factors, including the commonly included dimensions of attachment, identity and dependence, played a role in farmers' perceived challenges. For example, respondents more economically dependent on farming perceived greater challenges. We found that farmers' challenge perceptions regarding reduced yield and lack of time/labor significantly decreased as years of usage increased, implying that time and experience could dilute some challenges faced by farmers. Our findings indicate that social network use, technical guidance and economic subsidies are likely to address the concerns of farmers and facilitate their adoption of conservation practices.

Emerald ash borer (EAB) (Agrilus planipennis), an invasive nonnative beetle, is responsible for the mortality of ash trees in the eastern and midwestern United States. Despite efforts to contain this beetle through various control options, human-induced spread of EAB has caused damage to ash forests in many states. Because most ash trees are under private ownership, it is important to understand how landowners evaluate the risk of EAB and perceive the effectiveness of various control options. A mail survey of private forest landowners was conducted in Kentucky in 2020 to assess their awareness and perception of various control options of EAB infestation. Results from this survey suggest that landowners are concerned about EAB and the associated increased risks, reduced quality of scenic views, and increased cleanup costs. Landowners experiencing EAB infestation believed that EAB management needs collective actions and that current efforts by government agencies are not sufficient. However, few landowners are taking actions themselves to manage EAB on their property. These findings shed light on the extent to which landowners are concerned about EAB impact and emphasize the need for development of effective control options and outreach programs to increase landowner engagement and actions in EAB control and management. Study implications: This study assessed forest landowners’ knowledge and attitudes about emerald ash borer (EAB) and their perceptions on the effectiveness of various control options. The majority of landowners who have EAB on their property expressed concerns about safety and aesthetics but were generally pessimistic about control efforts. Our results highlight the need for additional efforts to not only increase the adoption rate of possible EAB control options but also develop new ways to effectively manage EAB. Additionally, tailored outreach programs are critical to increase landowner engagement in controlling EAB infestation and the management of other similar forest health threats in the future.

Landowner satisfaction with conservation programs affects their participation decisions and subsequently effectiveness of these programs in improving environmental quality. This study determined the influence of landownership goals, environmental concerns, frequency of contacts with federal agencies, and socioeconomic factors on landowner satisfaction with available conservation programs in the Mississippi Alluvial Valley and East Gulf Coastal Plain sub-geographies of the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative. A generalized ordered logit model for each conservation program was constructed to analyze factors influencing landowner satisfaction levels with these programs. Of the 14 federal conservation programs assessed, the top programs, based on a satisfaction level, included Conservation Reserve Program (CRP), Conservation Technical Assistance (CTA), Environmental Quality Incentives Program (EQIP), Conservation Stewardship Program (CSP), and Agricultural Conservation Easement Program (ACEP). The size of agricultural land owned, landownership goals including profit-making and personal recreation, concerns about wildlife habitat losses, and frequent contacts with federal agencies were positively related to landowner satisfaction levels. Better strategies addressing landowner’s environmental concerns, communicating technical knowledge, clarifying contract terms, and supporting financial resource leveraging will help reach the enrolled and non-enrolled landowners to increase their participation in conservation efforts.

Increasing flow of foreign remittance in low- and middle-income countries has facilitated international trade and increased economic activities. With time-series modeling of data in Nepal, one of the developing countries with high remittance flow, this study analyzed determinants of timber imports and evaluated the short- and long-run effects of foreign remittance on timber imports. Results from the vector error correction model showed that foreign remittance inflow was positively related to both roundwood and sawnwood imports in long run. However, timber imports had negative long-run relationship with GDP growth suggesting that import-based timber utilizing industry have not created comparative advantage in timber market. Short-run dynamic models indicated that demand for sawnwood in domestic market is more stable than for roundwood. As foreign remittance inflow and the national economy continue to grow, ensuring the continued supply of quality sawlogs at a cheaper rate from domestic producers may help sustain the growth of timber industry, decrease foreign dependence on timber products, and help reduce national trade deficits in the long run.

Distributional specifications of the willingness-to-accept function affect the accuracy of welfare estimates when the contingent valuation model includes unsure responses. By exponentiating the bid variable, we implemented an improved methodological approach to estimate four discrete choice models reflecting treatment of unsure responses. Landowners required an average compensation of $93 acre⁻¹ year⁻¹ to participate in a 10-year conservation program. The probability of participation was positively influenced by payment amount, concern about wildlife habitat loss, contact frequency with the Natural Resources Conservation Service, and education level. Findings will help determine regional-level budgets for various conservation scenarios facilitating an increased production of ecosystem services. Conservation agencies can decrease landowner uncertainty that arises from limited information about conservation programs and motivate landowners to enroll in a conservation program facilitating an increased production of ecosystem services by offering adequate monetary incentives. Conservation agencies can provide similar financial compensation for conservation of bottomland hardwoods and pine stands but will most likely need to offer greater compensation for the protection of forests prone from impacts by wildfires, hurricanes, and tornadoes. Available funding should be prioritized for conservation of critical habitats and freshwater sources vulnerable to land disturbances.

We assessed hunters’ willingness to participate in a scheme to recover the costs associated with processing diseased game. The results indicated that fifty-one percent of the hunters in a region affected by chronic wasting disease are interested in such a scheme and willing to pay an average of $20 per animal. Their willingness to participate is affected by risk perception, hunting experience, use of processing services, and income. Further, establishing such a market-based scheme would be financially profitable to game processors and helpful to wildlife agencies interested in encouraging hunters’ harvest to reduce herds and facilitate effective disease surveillance.
