Article Citation - WoS: 3Citation - Scopus: 4Rare Earth Elements in the Global Economy: Usage, Recovery, and the Quest for Supply Security – A Review(Springer Heidelberg, 2026) Top, Soner; Ayten, Asim Mustafa; Altiner, Mahmut; Demir, Idris; Kursunoglu, SaitOften described as the vitamins of modern industry, rare earth elements (REEs) are indispensable for the deployment of low-carbon and clean energy technologies. However, ensuring a secure and sustainable REE supply remains a major challenge due to the strong interdependence between application-driven demand, extraction and processing technologies, and the geopolitical concentration of resources. This review adopts an integrated analytical framework in which these three dimensions are treated as interconnected components shaping the resilience of global REE supply chains. First, the major application sectors of REEs are examined to clarify how emerging energy and advanced manufacturing technologies drive demand for specific elements and amplify their strategic importance. Second, extraction and processing technologies are reviewed in relation to both primary and secondary resources, highlighting how technological maturity, process selection, and material characteristics constrain or enable supply expansion. Finally, geopolitical and strategic aspects of the REE supply chain are analyzed to demonstrate how resource concentration, policy instruments, and international dependencies directly influence technological deployment and industrial competitiveness. By explicitly linking application-driven demand, technological pathways for extraction and processing, and geopolitical supply structures within a unified framework, this review provides a coherent understanding of the systemic challenges facing the REE sector and identifies key leverage points for improving the robustness and sustainability of REE supply chains in the context of the global clean energy transition.Article Citation - WoS: 13Citation - Scopus: 12The Role of Spatial Planning for Sustainable Tourism Development: A Theoretical Model for Turkey(Inst Tourism, 2012) Dede, Okan Murat; Ayten, Asim MustafaPlanning concept is an important concept for realizing the benefits of the tourism sector for localities, public and environment. Planning is a broad term covering several stages from national strategic decisions to unique design applications. Spatial planning is an important aspect of planning with a focus on physical planning in various sectors as well as tourism. The importance of planning has increased with the prominence of a second concept; sustainability. Since the 1970' s, sustainability has continuously gained importance in all socio economic aspects of human beings. It is also important for the tourism sector as this sector has effects on the environment. This article tackles the role and importance of physical planning for the development of sustainable tourism concept. For this reason, a model is built for sustainable tourism development in Turkey as Turkish legislation system regarding planning and tourism should be improved in terms of sustainability. The aim of the article is to determine how to integrate spatial planning to sustainable tourism development and to decide the possible pathways within sustainable tourism development. The model considers all stages from large scale decisions to architectural design within a comprehensive manner. This model could be utilized to deal with all aspects of planning, such as policies, strategies, spatial decisions, building structuring, density, site planning and architecture.Article Citation - Scopus: 12The Role of Spatal Planning for Sustainable Tourism Development: A Theoretical Model for Turkey(Institute for Tourism tourism@iztzg.hr, 2012) Dede, Okan Murat; Ayten, Asim MustafaPlanning concept is an important concept for realizing the benefits of the tourism sector for localities, public and environment.
