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.

本研究中考虑的研究假设是，在干旱环境中对海滩使用和管理采取的决策可能会导致其构成的海滩沙丘系统的生物地貌过程发生重大变化。不同的信息源和地理信息系统被用来对干旱海滩沙丘系统后岸地区的海滩设备、服务和使用之间的可能相关性进行时空分析，例如名为 Playa del Inglés 的海滩（大加那利岛）岛，西班牙）和在同一地区检测到的环境变化。研究中考虑的时期涵盖从 1961 年（岛上大众旅游发展之前）到 2018 年。在研究期间检测到植被覆盖的显着变化，以及侵蚀（地形和侵蚀性风沙地貌）和前缘破碎的整体增加以及地貌恢复力的下降。该研究不仅发现了管理决策与环境影响之间的关系，而且今天仍然可以感受到管理决策对 1970 年代和 1980 年代海滩使用的环境影响。此外，这些结果还强化了这样一种观点，即基于科学研究（管理研究二项式）结果做出的管理决策可以导致更环保的可持续行动。1970 年代和 1980 年代对海滩使用的管理决策对环境的影响在今天仍然存在。此外，这些结果还强化了这样一种观点，即基于科学研究（管理研究二项式）结果做出的管理决策可以导致更环保的可持续行动。1970 年代和 1980 年代对海滩使用的管理决策对环境的影响在今天仍然存在。此外，这些结果还强化了这样一种观点，即基于科学研究（管理研究二项式）结果做出的管理决策可以导致更环保的可持续行动。
