Isotopic data obtained from human remains can provide information about an individual's origin, migration, and diet. We evaluate the usefulness of carbon, oxygen, strontium, and lead isotopes for forensic investigations by comparing data from Bulgarian teeth with data from other regions. Geo‐referencing based on oxygen or strontium isotopes can be misleading due to overlap with other countries in Europe and other continents. Carbon and lead isotopes, in combination with oxygen and strontium isotopes, provide the most useful information for identification of local vs foreigner status. In particular, high‐precision Pb isotopes show a distinct “Bulgarian” range; however, it is possible that individuals from other countries in Eastern Europe and/or central to western Asia could have overlapping isotopic values. Additional high‐precision multi‐isotope data from modern humans from different regions in the world are required to transition from speculative to more quantitative estimation of a geographical place of origin for unidentified human remains. 相似文献

In the south of the biodiversity‐rich Indonesian province of Papua, a large agricultural program is planned for the districts around Merauke, with the ostensible aim of helping to meet Indonesia's food requirements. Questions arise over the scheme's compliance with national laws and sustainability policies, as well as its likely impacts on indigenous livelihoods and biodiversity. It is also contrary to the recent low‐carbon development priorities of the provincial and national governments. For the initiative to be consistent with law and policy, therefore, considerably improved planning effort would be needed, taking into account many factors that have so far been ignored. 相似文献

This article examines, first, how environmental concerns have shaped British politics since 1945, making the environment an object of governance; and second, how political developments have an environmental history, focussing on the environmental demands of social democracy. It contends that environmentalism should be considered alongside other political ideologies, such as socialism and feminism, as helping to constitute the modern British state and the evolving relationship between government and the citizen. It considers how the management of the terrestrial environment became a hotly contested matter in the postwar decades, drawing a distinction between the politics of ‘landscape preservation’ and ‘nature conservation’. This discussion is related to access politics and questions of rural governance and regulation, particularly with respect to the agricultural sector. The article concludes with a discussion of some current environmental concerns, reflecting on the possible transition from today's ‘carbon democracy’ to tomorrow's ‘renewable democracy’. 相似文献

Environmental degradation poses a severe threat to life on earth. Similarly to other countries, emerging seven (E-7) countries have been struggling to decrease their dependence on non-renewable energy sources by adopting environment friendly technologies for reducing environmental deterioration and to achieve sustainable development goals (SDGs) of the United Nations. In present study, we reassessed the technological policies of E-7 countries, and addressed the issues of affordable and clean energy, institutional quality (IQU), and sustained economic growth (EGR) to address the problem of environmental deterioration. For this purpose, we have investigated the role of renewable energy consumption (REC), technological innovations (TINs), IQU, and EGR on CO2 emissions (CE) by using the panel quantile regression (PQR) for the period from 1996 to 2020. The empirical outcomes of FGLS reveal that a 1% increase in REC, TIN, and IQU reduces the CE by 0.145%, 0.233%, and 0.249%, while a 1% rise in EGR and population (POPU) raises the CE by 0.993% and 1.546% respectively. Similarly, the results of PQR demonstrate that REC, TIN, and IQU reduce CE, whereas EGR and POPU increase environmental degradation. The impact of TIN on CE is high at lower quantiles and low at higher quantiles. The impact of IQU on CE is low at lower quantiles and high at higher quantiles Based on these findings, we have recommended a comprehensive SDG-oriented policy framework, so that E-7 countries can make progress towards achieving the objectives of SDG 16, SDG 13, SDG 7, SDG 8, and SDG 9. 相似文献

Since 2014, carbon taxes have been spreading in South America. Counterintuitively, while they are primarily considered climate policies, their adoption has been largely driven by causes unrelated to the reduction of greenhouse gas emissions. The carbon tax policymaking literature has overlooked the causes that trigger the causal mechanisms for adopting carbon taxes and has instead centered on parts of the causal mechanism. Focusing on the very beginning of the process, namely the causes triggering the decision to pursue carbon taxes in Argentina and Uruguay, this study both contributes to the carbon tax policymaking literature and to the burgeoning application of logical Bayesian analysis in qualitative studies. According to previous studies, the pursuit of carbon taxes inherently entails political challenges linked, among others, to its potential regressive impacts and effects on industries, which makes the sudden rise of carbon taxes in Argentina and Uruguay surprising. Based on 26 expert interviews and a desk review, the study applies a logical Bayesian analysis to study potential causes structured around mutually exclusive hypotheses consistent with the carbon tax policymaking literature. It shows that the causes for pursuing carbon taxes in Argentina and Uruguay are not primarily related to mitigation. Instead, Argentina conceived carbon taxation as part of a broader reform of its fiscal system, and Uruguay as a way to make explicit the already high implicit carbon price. 相似文献

当今社会,低碳理念在国际贸易中已然形成一种新风尚。但是,当我们提倡发展低碳经济的同时,也不得不正视国际贸易中低碳壁垒的快速发展。在此背景下我们可以清楚地看到,低碳壁垒作为一种新型非关税壁垒正在逐步成为中国开展对外贸易的新障碍。对这一问题进行探讨具有重大的理论和现实意义。本文在介绍低碳经济时代背景的基础上,剖析了低碳壁垒形成的主要原因,并进一步阐明了其主要表现形式和对我国出口贸易的影响,在此基础上,提出了健全我国应对低碳壁垒的法律机制的意见与建议,以期对我国在实践中应对低碳壁垒有所帮助和启发。 相似文献

为了研究不同土地利用方式的碳排放评价,特以山西宁武县为例进行考察,结果表明：宁武县的土地利用方式是低碳型的,林地对其低碳土地利用方式的形成贡献最大,降低建设用地能耗是宁武县实现低碳土地利用方式的重要途径。宁武县的模式可以为其他县土地利用和经济社会的发展提供参考。 相似文献

全球气候变化对各国产生了一系列的影响,碳排放权已成为新兴的交易客体,国际碳排放权的产生与发展,既为我国带来机遇,也使我国面临挑战。我国碳排放权交易市场尚处于起步阶段,建立与完善我国碳排放市场机制显得尤为重要与迫切。因此,我们应当借鉴国际碳排放权交易的经验,从法律、政策、信息透明度、政府职能等方面进行改进。 相似文献
