This article comes from a concern about the impact of the market system on Quebec's forest sector. Comparisons between Sweden, the United Kingdom, the United States and Quebec allow a clear picture of the situation. It is shown that the new Quebec forest system could bring elements of solution. This system has to deal with the problem of an oversized public domain and with the tack of economical foundation for the forest management program it promotes. Key words: Forest allotment, public domain, stumpage

This study explores the impact of environmental policies and human development on the CO2 emissions for the period of 1995–2015 in the Group of Seven and BRICS economies in the long run through panel cointegration and causality tests. The causality analysis revealed a bilateral causality between environmental stringency policies and CO2 emissions for Germany, Japan, the United Kingdom, and the United States of America, and a unilateral causality from CO2 emissions to the environmental stringency policies for Canada, China, and France. On the other hand, the analysis showed a bilateral causality between human development and CO2 emissions for Germany, Japan, the United Kingdom, and the United States of America, and unilateral causality from CO2 emissions to human development in Brazil, Canada, China, and France. Furthermore, the cointegration analysis indicated that both environmental stringency policies and human development had a decreasing impact on the CO2 emissions.

Abstract Because of the long-standing Canada-United States lumber trade dispute and the current pressure on the world's forests as a renewable energy source, much attention has been directed toward the modelling of international trade in wood products. Two types of trade models are described in this book: one is rooted in economic theory and mathematical programming, and the other consists of two econometric/statistical models--a gravity model rooted in theory and an approach known as GVAR that relies on time series analyses. The purpose of the book is to provide the background theory behind models and enable readers to easily construct their own models to analyze policy questions, whether in forestry or another sector. Examples in the book illustrate how models can be used to say something about a variety of issues, including identification of the gains and losses to various players in the North American softwood lumber business, and the potential for redirecting sales of lumber to countries outside the United States. The discussion is expanded to include other products besides lumber, and used to examine, for example, the effects of log export restrictions by one naton on all other forestry jurisdictions, the impacts of climate policies as they relate to the global forest sector, and the impact of oil prices on forest product markets throughout the world.

Abstract An array of policy instruments has been adopted across the United States in an effort to promote greater wood-to-energy uses. This research elicited attitudes toward wood-to-energy policy instruments among forest sector stakeholders to identify the most preferred policy tools. Test statistics identified differences between perceptions from US South and non-US South respondents regarding the capacity of tax incentives; subsidies and grants; rules and regulations; education; and consultation to meet policy ecological, economic, social, and political criteria. Examples of particular instruments adopted by various states were used to evaluate their capacity in addressing specific energy, forest management, and market dimensions of wood-to-energy policy. Results suggest preference for the implementation of education programs and the adoption of tax incentive instruments, followed by rules and regulations. US South respondents have less favorable views of subsidies and grants and rules and regulations than respondents from the rest of the country to meet policy evaluation criteria. Based on the analysis of state-specific policy tools, tax incentives were deemed the best positioned to generate more renewable energy from woody feedstocks and education and consultation were the best suited to meet energy and sustainable forest management objectives. A combination of approaches will be the most adequate to meet multiple policy criteria.

AbstractThe outbreak of COVID-19 has an undeniable global impact, both socially and economically. March 11th, 2020, COVID-19 was declared as a pandemic worldwide. Many governments, worldwide, have imposed strict lockdown measures to minimize the spread of COVID-19. However, these measures cannot last forever; therefore, many countries are already considering relaxing the lockdown measures. This study, quantitatively, investigated the impact of this relaxation in the United States, Germany, the United Kingdom, Italy, Spain, and Canada. A modified version of the SIR model is used to model the reduction in lockdown based on the already available data. The results showed an inevitable second wave of COVID-19 infection following loosening the current measures. The study tries to reveal the predicted number of infected cases for different reopening dates. Additionally, the predicted number of infected cases for different reopening dates is reported.

A debate is ongoing on the significance and appropriateness of the NOVA classification as a tool for categorizing foods based on their degree of processing. As such, the role of ultra-processed food (UPF) on human health is still not completely understood. With this review, we aimed to investigate the actual level of consumption of UPF across countries and target populations to determine the impact in real contexts. Suitable articles published up to March 2021 were sourced through the PubMed and SCOPUS databases. Overall, 99 studies providing data on the level of UPF consumption expressed as the percentage of total energy intake were identified, for a total of 1,378,454 participants. Most of them were published in Brazil (n = 38) and the United States (n = 15), and the 24 h recall was the most-used tool (n = 63). Analysis of the results revealed that the United States and the United Kingdom were the countries with the highest percent energy intake from UPF (generally >50%), whereas Italy had the lowest levels (about 10%); the latter was inversely associated with adherence to the Mediterranean diet. High variability was also observed based on sex, age, and body mass index, with men, young people, and overweight/obese subjects generally having higher levels of consumption compared to older subjects. Overall, our findings underline the large differences in UPF intake. Since most of the observations derived from studies conducted with food questionnaires are not specifically validated for UPF, further efforts are essential to confirm the results previously obtained and to investigate further the association between UPF consumption and health status, also considering the actual contribution within different dietary patterns, which has been less investigated to date.

This paper examines the impact of the Public Utilities Regulatory Policies Act (PURPA) in the United States and the Energy Act 1983 in the United Kingdom on the nature of the purchase tariffs for co-generators and combined heat and power (CHP) plant, and considers the reasons why the prospects for investment by private generators might be enhanced in the United States.
