“…), remote sensing techniques are preferred. Satellite and aerial remote sensing have certainly improved our knowledge and assessment of coastal wetland dynamics [32], but most of the studies focus on biomass evaluation [33][34][35][36] rather than geomorphological changes. In these environments rates of accretion and elevation changes range from millimetric to centimetric, thus creating the need for high spatial and vertical resolutions able to perform reliable interpretations.…”

The use of Unmanned Aerial Vehicles (UAV) on wetlands is becoming a common survey technique that is extremely useful for understanding tidal flats and salt marshes. However, its implementation is not straightforward because of the complexity of the environment and fieldwork conditions. This paper presents the morphological evolution of the Po della Pila tidal flat in the municipality of Porto Tolle (Italy) and discusses the reliability of UAV-derived Digital Surface Models (DSMs) for such environments. Four UAV surveys were performed between October 2018 and February 2020 on an 8 ha young tidal flat that was generated, amongst others, as a consequence of the massive sediment injection into the Po Delta system due to the floods of the 1950s and 1960s. The DSM accuracy was tested by processing (i.e., photogrammetry) diverse sets of pictures taken at different altitudes during the same survey day. The DSMs and the orthophotos show that the tidal flat is characterised by several crevasse splays and that the sediment provision depends strictly on the river. During the study period, the sediment budget was positive (gaining 800 m3/year and an average rate of vertical changes of 1.3 cm/year). Comparisons of DSMs demonstrated that neither lower flight altitudes (i.e., 20–100 m) nor the combination of more photos from different flights during the same surveys necessarily reduce the error in such environments. However, centimetric errors (i.e., RMSEs) are achievable flying at 80–100 m, as the increase of GCP (Ground Control Point) density is the most effective solution for enhancing the resolution. Guidelines are suggested for implementing high-quality UAV surveys in wetlands.

“…Beberapa studi menunjukkan bahwa penggunaan drone dalam pemantauan kondisi fisik pesisir telah berhasil dilakukan di berbagai negara seperti Amerika Serikat (Klemas, 2013), Kanada (Briggs et al, 2017), dan Australia (Roelfsema et al, 2015). Dalam studi lain, Chowdhury et al ( 2017) menyebutkan bahwa pemanfaatan drone dalam pemantauan kondisi fisik pesisir dapat membantu dalam mengidentifikasi dan memetakan wilayah yang terdampak oleh abrasi.…”

Kawasan pesisir sering menghadapi tantangan lingkungan yang kompleks, seperti abrasi, deforestasi, pencemaran, dan kegiatan ilegal yang merusak ekosistem laut. Sayangnya, mayoritas masyarakat pesisir sebagai aktor kunci kegiatan monitoring masih terbatas dalam mempelajari dan mengaplikasikan teknologi yang relevan. Sehingga laju upaya konservasi dan rehabilitasi pesisir tidak bisa mengimbangi laju kerusakan yang terjadi. Oleh karena itu, penting untuk mengembangkan sistem pemantauan yang efektif untuk menjaga keberlanjutan ekosistem pesisir. Sistem pemantauan ini dikembangkan untuk meningkatkan keterampilan masyarakat dalam memanfaatkan aplikasi dan wahana pemetaan sebagai alat monitoring, untuk meningkatkan efektivitas konservasi dan rehabilitasi pesisir. Metode yang digunakan adalah pendekatan partisipatif, yang memungkinkan masyarakat berkolaborasi dengan perguruan tinggi dalam melakukan monitoring berbasis aplikasi dan wahana pemetaan, khususnya dalam pemanfaatan drone. Peserta kegiatan adalah enam kelompok masyarakat konservasi (POKMASI) yang berada di pesisir Kabupaten Karawang. Evaluasi kegiatan dilaksanakan melalui observasi lapangan, FGD, serta analisis terhadap data spasial yang dihasilkan POKMAS. Hasil yang signifikan dari kegiatan ini adalah meningkatnya partisipasi masyarakat dalam pemantauan kawasan pesisir, pengayaan metode pengawasan, terbentuknya jejaring komunikasi yang efisien, serta aksi kolektif untuk menjaga kawasan konservasi dan rehabilitasi pesisir Kabupaten Karawang.
