Tanzania, arguably mainland Africa's most important nation for conservation, is losing habitat and natural resources rapidly. Moving away from a charcoal energy base and developing sustainable finance mechanisms for natural forests are critical to slowing persistent deforestation. Addressing governance and capacity deficits, including law enforcement, technical skills, and funding, across parts of the wildlife sector are key to effective wildlife protection. These changes could occur in tandem with bringing new models of natural resource management into play that include capacity building, corporate payment for ecosystem services, empowering nongovernmental organizations in law enforcement, greater private‐sector involvement, and novel community conservation strategies. The future of Tanzania's wildlife looks uncertain—as epitomized by the current elephant crisis—unless the country confronts issues of governance, embraces innovation, and fosters greater collaboration with the international community. 相似文献

We used linear and multivariate models to examine the associations between geography, biodiversity, per capita economic output, national spending on conservation, governance, and cultural traits in 55 countries. Cultural traits and social metrics of modernization correlated positively with national spending on conservation. The global distribution of this spending culture was poorly aligned with the distribution of biodiversity. Specifically, biodiversity was greater in the tropics where cultures tended to spend relatively less on conservation and tended to have higher collectivism, formalized and hierarchical leadership, and weaker governance. Consequently, nations lacking social traits frequently associated with modernization, environmentalism, and conservation spending have the largest component of Earth's biodiversity. This has significant implications for setting policies and priorities for resource management given that biological diversity is rapidly disappearing and cultural traits change slowly. Therefore, we suggest natural resource management adapt to and use characteristics of existing social organization rather than wait for or promote social values associated with conservation spending. Supporting biocultural traditions, engaging leaders to increase conservation commitments, cross‐national efforts that complement attributes of cultures, and avoiding interference with nature may work best to conserve nature in collective and hierarchical societies. Spending in modernized nations may be a symbolic response to a symptom of economic development and environmental degradation, and here conservation actions need to ensure that biodiversity is not being lost. 相似文献

近年来,随着污染治理和生态环境保护力度的加大,京津冀区域生态环境质量持续改善,但是以PM2.5为特征污染物的大气污染问题仍然不容小觑。选取了2015年1月1日—2022年11月30日京津冀及周边31个城市的PM2.5浓度数据,结合引力模型与皮尔逊相关指数,构建了京津冀及周边城市PM2.5污染的空间关联网络,并对该网络的整体特征与模体季节变化进行了统计分析。结果表明：邢台、石家庄、邯郸3个城市的度值、中介中心性、接近中心性均排名前3,它们在该网络中处于核心位置,与多个城市存在较强的PM2.5污染空间关联,对于控制PM2.5污染的空间溢出具有较为重要的作用;模体的四季关联网络密度和平均度相差不大,但均较高,各城市间的PM2.5存在较强的空间关联,其中在冬季网络密度最高,石家庄、邢台、衡水在模体四季关联网络中起着重要作用。对于在京津冀及周边城市PM2.5污染空间关联网络中处于核心位置的城市,在加强自身PM2.5治理的同时,应制定政策减弱其对相邻城市PM2.5污染的空间溢出效应;根据不同季节模体的关联情况,制定相应的协同治理政策,加强对这些模体城市PM2.5污染的协同治理,同时减弱它们之间的PM2.5污染空间关联与溢出效应。

Drawing on resource dependency and upper echelons theories, we examine the relationship between directors' international orientation (IO) and the scope of non-financial disclosures (NFD) in a two-tier board structure. Evidence from a regression analysis on a sample of non-financial firms listed on the Warsaw Stock Exchange for the 2014–2018 period shows that the IO of supervisory board members significantly and positively impacts the scope of NFD. We also find that women with IO influence the scope of NFD, whereas accounting and finance experience decreases the focus on NFD elements, especially environmental information. The results imply that both the IO of the supervisory board and the bundle of characteristics facilitate the move toward sustainable development. The findings of our study should be of interest to companies, regulators and policymakers to integrate sustainability practices into their corporate strategies. 相似文献

This study aims to identify the effect of board diversity on environmental policy in Latin American companies. This research focuses on 11 industrial sectors in Brazil, Mexico, and Chile that took into consideration a broader extension of environmental policy, involving practices regarding resource use, emissions reduction, and innovation. Drawing on corporate governance (CG) and corporate social responsibility (CSR) relationships, a regression analysis was conducted with 1214 firm-year observations from 181 companies. Our results indicate that the predominantly weak CG in Latin America might favour the use of manipulative environmental policy decisions. Board diversity does not have a relevant influence on CSR activities, as environmental issues are only taken into account so far as the cost of natural resources, while issues such as environmental innovation and reducing emission are not part of the agenda. In Brazil and Chile, independent directors have no significant effect on environmental policy decisions, while in Mexico, a less independent board grants managers greater discretion to establish an environmental policy, whereas in all three countries, board gender diversity has no significant effect. The theoretical insights drawn from this study reinforce that board composition, as an internal CG mechanism, is insufficient to overcome the institutional voids and give protagonist to sustainability issues in Latin America, reiterating the need for more robust CG mechanisms to coerce CSR. 相似文献

Maintaining good relationships with internal and external stakeholders can help companies gain competitive advantages and mitigate risks associated with social factors. However, building social capital is not an easy task, as it requires management to prioritize long-term goals over short-term gains. The board of directors is expected to ensure that management maximizes shareholders' value, commits to strengthening its relationship with stakeholders, and engages in socially responsible activities. These expectations depend heavily on the quality and effectiveness of the board. Certain board characteristics may impede its ability to drive long-term vision or create good stakeholder relationships, leading to a decline in the company's social capital. In this paper, we analyze board characteristics of publicly listed US firms, focusing on staggered boards, and find evidence supporting the agency theory that staggered boards adversely affect firms' social capital. To ensure the robustness of our analysis, we conduct additional analyses including propensity score matching, entropy balancing, and instrumental-variable analysis. 相似文献

This paper examines the influence of board gender diversity on the Environmental, Social and Governance (ESG) disclosure quality of energy firms. Particularly, the study evaluates the possible differences in the influence of board gender diversity on the ESG disclosure practice of firms in developed and developing nations. Previous studies have used single country based analysis and presented diverse results, however this study uses data from 48 countries from both developed and developing nations over a period of 13 years (from year 2004 to 2016). The study finds that, in general, female directors favorably influence the quality of disclosure of ESG and its individual components (except governance). However, sub-sample analysis of firms in developed and developing nations finds that the relationships are significant only for the sample of firms in developed nations. The results show that there are differences in the role female directors play in influencing ESG disclosure for developed and developing countries, thus this study highlights the importance of accounting standards in strengthening the contribution of female directors on corporate boards, especially in developing countries. The study also highlights the need to assess ESG components separately, in addition to the overall component, when conducting studies on ESG. 相似文献
