The research hypothesis considered in this study is that decisions adopted on beach use and management in arid environments can result in significant changes in the biogeomorphological processes of the beach-dune system of which it forms part. Different information sources and geographical information systems were used to make a spatiotemporal analysis of possible correlations between the presence of beach equipment, services and uses in the backshore area of an arid beach-dune system, such as the beach named Playa del Inglés (Gran Canaria island, Spain) and environmental changes detected in the same area. The period considered in the study covers from 1961 (before the development of the mass tourism on the island) to 2018. Significant variations in vegetation cover over the course of the study period were detected, as well as an overall increase in erosion (topographic and erosive aeolian landforms) and foredune fragmentation and a decrease in geomorphological resilience. The study found not only relationships between management decisions and environmental impacts, but also that environmental impacts of management decisions on beach use made in the 1970s and 1980s continue to be felt today. Moreover, the results also reinforce the idea that management decisions made based on the results of scientific research studies (management-research binomial) can lead to more environmentally sustainable actions.
本研究的研究假设是，在干旱环境中对海滩使用和管理的决策可能会导致海滩-沙丘系统的生物地貌过程发生重大变化，而该系统是其中的一部分。本研究使用了不同的信息来源和地理信息系统，对干旱海滩-沙丘系统后滨区（如西班牙大加那利岛的 Playa del Inglés 海滩）中海滩设施、服务和用途的存在与同一地区检测到的环境变化之间可能存在的相关性进行时空分析。研究中考虑的时间段为 1961 年（在该岛大规模旅游业发展之前）至 2018 年。研究期间检测到植被覆盖的显著变化，以及侵蚀（地形和侵蚀性风成地貌）、前沙丘破碎化的总体增加和地貌恢复力的下降。研究不仅发现了管理决策与环境影响之间的关系，还发现了 20 世纪 70 年代和 80 年代的海滩使用管理决策的环境影响至今仍在持续。此外，研究结果还进一步证实了这样一种观点，即基于科学研究结果做出的管理决策（管理-研究组合）可以导致更具环境可持续性的行动。
