The urgency of restoring ecosystems to improve human wellbeing and mitigate climate and biodiversity crises is attracting global attention. The UN Decade on Ecosystem Restoration (2021–2030) is a global call to action to support the restoration of degraded ecosystems. And yet, many forest restoration efforts, for instance, have failed to meet restoration goals; indeed, they worsened social precarities and ecological conditions. By merely focusing on symptoms of forest loss and degradation, these interventions have neglected the underlying issues of equity and justice driving forest decline. To address these root causes, thus creating socially just and sustainable solutions, we develop the Political Ecology Playbook for Ecosystem Restoration. We outline a set of ten principles for achieving long-lasting, resilient, and equitable ecosystem restoration. These principles are guided by political ecology, a framework that addresses environmental concerns from a broadly political economic perspective, attending to power, politics, and equity within specific geographic and historical contexts. Drawing on the chain of explanation, this multi-scale, cross-landscapes Playbook aims to produce healthy relationships between people and nature that are ecologically, socially, and economically just – and thus sustainable and resilient – while recognizing the political nature of such relationships. We argue that the Political Ecology Playbook should guide ecosystem restoration worldwide. 相似文献

Central elements of the challenges of the future are the population, supply and disposal trap, the question of how the increasing world population will be supplied with long‐lasting and effective sources of energy, raw materials and food? How do we deal with the problems of greenhouse effect, ozone hole, forest dieback, ground erosion, desertification and other environmental threats? Driven by the dynamics of the technical progress the world is in the midst of experiencing the transition from an industrial to an information society. The process of globalization is intrinsically tied to the information society and plays a vital role in the path to a new, digital development of the world. Therefore, new challenges have been added to the traditional ecological challenges at the beginning of the 21st century, which the world community must react swiftly to. 相似文献

Abstract This article presents a family program that extends the materials and meeting times of the Michigan Model Family Geography Challenge, including suggestions on creating a successful family night program. The article focuses on developing positive school-community relationships by inviting local community members to participate in fun academic lessons. In addition to watching the news together nightly, families meet four times during an eight-week period to engage in hands-on geography related activities. One lesson is introduced during each session and families work together to complete assigned tasks. Following the activity, families join together to eat and socialize. The program enhances geographic knowledge (including current events), positive family interactions, and school outreach. 相似文献

Permafrost engineering has been developing rapidly in recent years. Many projects have been undertaken with the latest technologies and show their importance in supporting regional social and economical development. For example, the Qinghai-Tibet Railway has been a milestone project in permafrost engineering. However, when designing and building infrastructures in cold regions, 相似文献

工程地质:科学、艺术和挑战从2014年全国工程地质年会看工程地质学科发展 总被引：1，自引：0，他引：1
本文是2014年太原全国工程地质学术年会的学术总结.这次会议以资源开发中的重大工程地质问题为题,聚集了全国800余位专家学者,通过15个大会报告, 3个分会场共69个报告,集中反映了我国工程地质学科在这一领域的进展.会议报告和论文展现出我国工程地质学科发展的几个特点: (1)紧密结合国家战略需求,敢于触碰国际工程地质前沿难点; (2)紧密结合经济发展的区域性问题为国家建设提供技术支撑; (3)中国工程地质走向世界,工程地质没有了国界.企业界活跃参与,学术交流走出了象牙塔; (4)高新技术在工程地质界广泛运用,促进工程地质大发展; (5)青年成为学术舞台的主力军; (6)中国工程地质学家开始哲学思考,中国的工程地质进入新的境界.本文也指出了我国工程地质面临的诸多挑战,一是基础理论研究落后于工程实践; 二是学科精神建设亟待加强,而最大的挑战正是学科精神的挑战. 相似文献

2015年12月在马里亚纳海沟"挑战者深渊"进行了定点样品采集,对温度、盐度、溶解氧、pH等环境参数进行了分析,讨论了营养盐的垂直分布特征、各形态营养盐结构特征及影响因素。研究发现,溶解氧在表层具有最大值,在1000 m左右出现极小值,而在8700 m深度具有较高溶解氧值(5.79 mg·L^-1),这可能与富氧水团的存在有关。硝酸盐表层含量较低,在1000和5367 m处出现双峰值。在表层水体中,溶解有机氮、磷是溶解总氮、溶解总磷的主要存在形式,表层以深,溶解无机氮、磷逐渐占据主导地位。磷酸盐表层含量最低,在1000 m处达到最大值,之后随着深度的增加浓度逐渐降低;硅酸盐在表层含量较低,在约4000 m处有最大值161.65μmol·L^-1,在4000 m以深,硅酸盐仍维持较高浓度。结果表明马里亚纳海沟"挑战者深渊"的溶解氧、pH及营养盐的垂直分布特征与大洋环流、海沟形态以及生物活动密切相关。 相似文献
