The California’s cap-and-trade program (California’s carbon market hereafter) allows forestland owners from any part of the contiguous United States to supply carbon credits to compliance entities. In this study, we estimate South Carolina (SC) private forestland owners’willingness to accept compensations to participate in the California’s carbon market using a contingent valuation method. Results: We estimate forestland owners’mean willingness to accept as$67 per acre per year. Our results reveal higher probability of participation of forestland owners with interests in preserving forest ecosystems than those who do not. Additionally, forestland owners who trust in information about climate change from scientists or government are willing to participate more than those who do not. Conclusions: Various factors hinder landowners’ability to participate in carbon markets. Forestland owners in SC consider legislative uncertainty and long-time commitment as the main barriers to participation in California’s carbon market. From this research, average forestland tenure in SC is 27 years, which is far less than the 100-year time commitment of the California’s carbon market. Of those who agreed to participate, choosing between adopting and not adopting any of the three main forest management practices in the California’s carbon market:28% are likely to adopt improved forest management (IFM) practices, 24% are likely to adopt reforestation due to understocked forestlands, and 14% are likely to adopt avoided conversion. In another development, the concept of aggregation has dominated discussions in the California’s carbon market of late. It is an advocacy to include small-scale forestlands in the California’s carbon market. To aggregate, different forestland owners will combine their forestlands to participate. We find that 79% of SC forestland owners are willing to aggregate to participate. However, this research is unable to determine how much total forestland is available in SC for carbon market. We recommend future research in the State on forestland owners’participation in carbon market should consider evaluating forestland availability.展开更多

Plastic bag litter serves as a negative environmental externality detrimental to animal health and natural beauty of the environment. In an effort to curtail the excessive use of plastic bags in Botswana, the government introduced a plastic levy targeted at consumers at retail points. This study uses primary data collected from 367 respondents randomly selected from six geospatially and purposively selected shopping malls to determine the consumers' willingness to pay(WTP) for continued plastic bag usage and their willingness to accept(WTA)to shift to eco-friendly alternatives. The results of the study revealed that open dumping and burning of plastic litter are more common in Maun than in Gaborone. It also showed that there is a significant relationship between the level of education and WTP. Further, there is a significant variation in income and education in respect to environmental awareness. The government should improve its efforts of sensitizing the public about the improper disposal of plastic bags.展开更多

To curtail these effects, vaccines are being approved for human trials. It is, therefore, important to know the possible vaccine coverage expected in each country. This study determined the willingness of Nigerians to accept and pay for COVID-19 vaccine. <strong>Methods:</strong> A cross-sectional web-based survey across all states of Nigeria was conducted via a structured e-questionnaire. Descriptive statistics, ANOVA and multinomial logistic regression were conducted. <strong>Result:</strong> A total of 502 responses were obtained from all six geopolitical zones of Nigeria, comprising 67.3% males (n = 338) and 32.7% females (n = 164). The results indicated that 34.7% (n = 167) are willing to accept the vaccine when given for free, 33.9% (n = 163) are not willing, and up to 31.4% (n = 151) are indifferent in their decision. Univariate analysis indicated the likelihood that education level could influence willingness to accept the vaccine (F = 2.408, p = 0.049). Rollout strategies may have an impact (p < 0.0001) on the willingness to accept the vaccine. These strategies include providing incentives, making it compulsory and paying for the vaccine with F = 186.983 and eta = 0.657, F =71.620 and Eta = 0.476, F = 108.696 and Eta = 0.552, respectively. <strong>Conclusion:</strong> The study revealed a possibility of the low willingness of Nigerians to accept COVID-19 vaccine. Providing incentives is likely to improve coverage, while making the vaccine compulsory may increase rejection. This study, therefore, serves as a gateway for government and policymakers on how best to prime and penetrate the society to achieve massive COVID-19 vaccine coverage in Nigeria.展开更多
