对我国政府在全球采掘业透明倡议中应持立场的思考和建议

历经10余年的发展,采掘业透明倡议已经发生了巨大变化,西方发达国家开始积极介入,主动宣布试点或计划实施。形势的变化要求我国及时调整以往所持立场。本文简要介绍了全球采掘业透明倡议的组织架构及运作、实施现状,深入分析了各利益相关方的动机,对其未来发展加以研判,并结合我国涉及采掘业透明倡议的情况,提出了新形势下我国短期内不宜实施,但须及时调整立场;鼓励金融机构和企业介入EITI和其他反腐败倡议;政府应考虑成为EITI的正式支持国。     

Origin,discovery, exploration and development status and prospect of global natural hydrogen under the background of “carbon neutrality”

Global energy structure is experiencing the third transition from fossil energy to non-fossil energy, to solve future energy problems, cope with climate change, and achieve net-zero emissions targets by 2050. Hydrogen is considered to be the most potential clean energy in this century under the background of carbon neutrality. At present, the industrial methods for producing hydrogen are mainly by steam-hydrocarbon (such as coal and natural gas) reforming and by electrolysis of water, while the exploration and development of natural hydrogen had just started. According to this literature review: (1) Natural hydrogen can be divided into three categories, including free hydrogen, hydrogen in inclusions and dissolved hydrogen; (2) natural hydrogen could be mainly from abiotic origins such as by deep-seated hydrogen generation, water-rock reaction or water radiolysis; (3) natural hydrogen is widely distributed and presents great potential, and the potential natural hydrogen sources excluding deep source of hydrogen is about (254±91)×10⁹ m³/a according to a latest estimate; (4) at present, natural hydrogen has been mined in Mali, and the exploration and development of natural hydrogen has also been carried out in Australia, Brazil, the United States and some European countries, to find many favorable areas and test some technical methods for natural hydrogen exploration. Natural hydrogen is expected to be an important part of hydrogen energy production in the future energy pattern. Based on a thorough literature review, this study introduced the origin, classification, and global discovery of natural hydrogen, as well as summarized the current global status and discussed the possibility of natural hydrogen exploration and development, aiming to provide reference for the future natural hydrogen exploration and development.©2022 China Geology Editorial Office.     

我国重要矿产资源战略性评价

重要矿产资源尤其是战略性矿产的安全保障历来是世界各国关注的重点之一。关于战略性矿产的研究,欧美等发达国家和地区已经建立了一套比较成熟的理论和方法,并不定期更新战略性矿产目录。而我国对于战略性矿产的研究相对较晚,尚未形成统一的内涵意义、评价体系和方法。为此,本文在重新界定战略性矿产内涵基础上构建供应风险-经济价值二维评价体系,运用定性和定量相结合的评价方法综合评价我国主要矿产资源的战略性。

Beyond the numbers: Understanding the value of vegetation to rural livelihoods in Africa

Different types of vegetation found in local environments are of value to rural livelihoods of many African households. However, the dominant way of expressing this value, which is mainly through economic valuation studies, is potentially limiting this knowledge’s usefulness in policy and research, due to the inability to present full picture. Using literature review and insights from field work, the paper argues that realized and notional values of vegetation to rural livelihoods are socially constructed and contested, and - in addition to understanding local livelihood context, which include social difference, and ecological dynamics - a focus on social institutions as terrains of negotiation is crucial. This means that resource value in rural livelihoods can be realized through contested and negotiated access arrangements that are mediated by complex institutions at local and external levels.

Commuting for rights: Circular mobilities and regional identities of Palestinians in a Jewish-Israeli town

Mobilities in settler states have become a defining feature of indigenous spatiality. This is mainly due to the structural disadvantage of indigenous communities in relation to urban locations. In Israel, Palestinian citizens are relocating to Jewish cities because of systemic discrimination, primarily in the allocation of land and housing construction permits in Arab locales. Yet, as this paper shows, their movement is neither unidirectional nor an one-time event, but ongoing and circular. Able to enjoy only certain economic and social rights in indigenous spaces and other rights in settler spaces, Palestinian citizens continuously commute between the two. Utilizing a human rights based approach, the paper unpacks Palestinian mobility practices to illuminate a lacuna in the literature, which has overlooked the quest for rights as a driving force of indigenous mobilities. The paper further demonstrates that circular mobilities become a generative act that connects the settler city to neighboring localities in a way that undermines the separation between ‘Jewish’ and ‘Palestinian’ spaces, and collapses the distinction between the ‘urban’ and ‘regional.’ Rather than attempting to integrate within the city, Palestinians incorporate the city within their own ethno-regional topography, thereby asserting their presence and a claim to the city-space itself.
