Titling land to conserve forests: The case of Cuyabeno Reserve in Ecuador

We used a mixed-methods approach to assess the impact of a ‘forest-friendly’ titling program on previously untitled lands surrounding the Cuyabeno Reserve in Ecuador. Such programs are part of an increasing trend in tenure formalization intended to simultaneously strengthen tenure security, reduce deforestation, and open the door for more incentive-based conservation programs. We use quasi-experimental methods to estimate and compare the impact of titling on forest outcomes for lands that are titled with certain limitations on the ownership bundle of rights, alongside lands titled but without these restrictions. This quantitative analysis is paired with results from a series of focus group interviews with landowners to understand their experiences with the titling effort, particularly tied to the restrictions. Our results point to a statistically significant impact of titling with restrictions on reducing deforestation by 34%, whereas titling without such restrictions resulted in no significant effect. When we explore impacts according to annual deforestation rates, the results suggest that titled lands are buffered from the surges in deforestation that otherwise occurred on untitled lands and more broadly across the region. While ‘forest-friendly’ restrictions had more of an effect on forest outcomes than titled lands without, the insights shared by landowners suggest important concerns about equity and unjust burdens on current households that could risk livelihood options for future generations.     

哈萨克斯坦主要矿产资源特征及矿业投资环境

哈萨克斯坦地处中亚核心位置,是丝绸之路经济带的重要节点和战略枢纽,具有丰富的矿产资源,地缘政治经济意义重大,是中国企业开展国际矿业投资合作的重要目标国之一。本文在系统梳理哈萨克斯坦基本国情、主要矿产资源特征及开发现状、地质工作程度和地矿管理体系等基础上,对哈萨克斯坦的矿业投资环境进行了评价,分析了矿业投资的有利和不利条件。研究认为哈萨克斯坦矿产资源禀赋优势突出,油气、铀、铬、金、钨、铅、锌及铜等矿种的资源储量居世界前列;全国仅有10%～15%的已探明矿产资源处于开发阶段,采矿业发展潜力巨大;哈萨克斯坦的总体投资环境优越,吸引外资力度逐渐加大,矿产勘探开发水平不断提升。但中国企业开展矿业投资也存在竞争力不足,以及面临政策法规不稳定、地质技术资料不可靠及运营等方面的风险。为此,建议中国投资者一方面要加强对哈萨克斯坦优势矿产的投资力度,积极拓展合作方式及合作领域;另一方面要注重与哈萨克斯坦各利益集团建立良好关系,结合企业优势,综合评价矿业项目,做好风险预警防范;同时,在投资过程中要尊重地方文化习俗,积极履行社会责任。     

Marine governance in an industrialised ocean: A case study of the emerging marine renewable energy industry

The world׳s oceans are currently undergoing an unprecedented period of industrialisation, made possible by advances in technology and driven by our growing need for food, energy and resources. This is placing the oceans are under intense pressure, and the ability of existing marine governance frameworks to sustainably manage the marine environment is increasingly being called into question. Emerging industries are challenging all aspects of these frameworks, raising questions regarding ownership and rights of the sea and its resources, management of environmental impacts, and management of ocean space. This paper uses the emerging marine renewable energy (MRE) industry, particularly in the United Kingdom (UK), as a case study to introduce and explore some of the key challenges. The paper concludes that the challenges are likely to be extensive and argues for development of a comprehensive legal research agenda to advance both MRE technologies and marine governance frameworks.     

Human dignity: A fundamental guiding value for a human rights approach to fisheries?

Recently, a human rights approach has been center-staged within fisheries governance as a response to the limits of private property rights in reducing insecurity and vulnerability among fishers and fishing communities. Despite its growing adoption in international legal frameworks and among civil society organizations, the conceptual pitfalls of the human rights approach to fisheries (i.e., its neoliberal tendencies and the neglect of collective rights and social duties) raised by critical scholarship remain largely unsettled, leading to practical concerns about whether such a framework will ultimately benefit fishers on the ground. To further contribute to the debate, this article presents a nuanced discussion of the human rights perspective by introducing the concept of human dignity. Specifically, it argues that human dignity, with its greater conceptual scope and depth, could act as a foundational value with which to mitigate some of the shortcomings of the human rights approach. The purpose here is suggestive rather than definitive and is aimed at highlighting the link that has not been clearly made between human rights and human dignity. I argue that heightened attention to human dignity has the potential to create wider support for the human rights approach and ultimately help facilitate its efficacy in fisheries.
