“…Urbanization often encroaches on soils of great ecological value, such as wetlands, dunes, forests…, but also by occupying areas prone to flooding or landslides. On the Atlantic coast of the TTA region, the analysis of LULC changes in Tahaddart coast (Aitali et al, 2020) showed a decrease in almost all the land use units between 1999 and 2019 except the built-up area, which shows a sharp increase. These changes are linked to the fact that the Tangier-Asilah prefecture, has experienced significant development in the last decade (Chattou, 2011), explaining the increase in the built-up area, to the detriment of the cultivated lands and the natural habitats (Rifai et al, 2018).…”

“…Each component of the risk equation, including the final outcome, was produced with a concept of multi-criteria decision-making (MCDM) theory following the approach described in section 2.2.1. using the geographic information systems (GIS) platform. The method is widely employed in research studies for regions with similar characteristics (e.g., Bagdanavicǐute et al, 2015;Satta et al, 2016;Satta et al, 2017;Aitali et al, 2020).…”

“…In fact, variables deemed to have a higher impact on the final risk were given a weight close to 100%, while variables deemed to have a lower impact were given a weight close to 0% (Torresan et al, 2012). This way of weighting was widely adopted to assess coastal risks associated with climate change at the regional (Torresan et al, 2012;Zhou et al, 2015;Satta et al, 2017) and local scales (Satta et al, 2016;Aitali et al, 2020), and as a metric for ranking risk mitigation strategies (Zhou et al, 2015).…”

“…It is home to a large amount of biodiversity and provides many ecosystem services. However, the shift of populations and activities from the hinterland to the coast, since the beginning of the century, has contributed to a strong 'artificialization' of the coasts, making them more exposed to various meteorological and marine hazards, and consequently more vulnerable and less resilient to coastal risks (Snoussi et al, 2008;Snoussi et al, 2009;Khouakhi et al, 2013;Satta et al, 2016;Aitali et al, 2020). Many coastal areas have already experienced a real estate boom and increased pressure on coastal dunes that are retreating or disappearing, exposing more and more property and people to flooding and coastal erosion (El Mrini et al, 2012;Kasmi et al, 2020;Flayou et al, 2021).…”

Coastal zones occupy a prominent position in the sustainable management perspective of Tangier-Tetouan-Al Hoceima (TTA) region because they accommodate a majority of the region’s population and contribute to the economic wellbeing of local communities. High demographic and economic pressures associated to climatic and environmental factors increase and intensify the vulnerability of these coastal areas. The latter are severely affected by climate change implications in the course of time, which lead to damage and loss in coastal low-lying zones. In practice, the risks related to climate change, as coastal risks, are frequently addressed, and assessing coastal risk in the context of climate change is a research priority. The aim of this work is to evaluate the flooding risk of TTA coasts, taking into account the inundation level related to the conditions of extreme wave (return period of 100-year) and extreme sea level rise. We firstly defined the coastal hazard zone that corresponds to the maximum inundation level of 13 m for the whole area. We then applied a Coastal Risk Index application at the Local Scale (CRI-LS) methodology to calculate forcing, vulnerability, exposure and risk indices using nineteen physical, environmental and socioeconomical variables. Findings show that coastal hazard zone of Tangier-Tetouan-Al Hoceima region is extremely exposed to coastal forcing. More than 50% of the hazard zones indicates highly vulnerable zones and highest exposure is generally focused on the most populated urban zones. In the light of this, the coastal risk mapping shows hotspot zones in terms of climate change-related coastal risks located at Tangier Bay, south of Tangier city, Fnideq and Martil coasts, Tetouan city and north of Ksar El Kbir city. This paper corresponds to a useful support that can help policy-makers in decision-making to quietly follow coastal planning and management processes and participate in preserving coastal areas for future generations, which support the sustainable development goals of Agenda 2030 started by the United Nations with the goal of eradicating all kinds of poverty.

“…The few villages in the area have a total population of about 45,043 and their inhabitants are living mostly on agriculture, fishing and sea salt production (RGPH 2014). In spite of these anthropic pressures, the Tahaddart estuary has preserved, almost entirely, its natural aspects, which is recommended when searching for past marine submersion deposits (Keating et al 2008;Aitali et al 2020). Since 1996, the area was classified by the Moroccan government as a Site of Biological and Ecological Interest (SIBE L11), and in 2005 as a RAMS AR zone under the name of "Complexe du bas Tahaddart" (Nachite et al 2008).…”

The Atlantic coast of Morocco has been exposed to marine submersion events from storm surges and tsunamis which have resulted in human and economic losses. The absence of long term records for these hazards makes it difficult to trace their behavior through time, which is the first step to prepare proactive adaptation strategies for events that may happen in the future. In this paper, we present a late Holocene record of marine submersion events along the Atlantic coast of Morocco using a 2.7 m sediment core sampled from the Tahaddart estuary. The sedimentological and geochemical analyses conducted on this geological archive showed a mud-dominated sequence with 14 allochthonous sandy layers (E1-E14) left by marine high-energy events. The deposition age of three layers (E1, E13 and E14) has been determined using conventional dating methods (210Pbex, 137Cs and 14C). The first layer, introduced as E1 seems to fit with the great Lisbon tsunami in 1755 CE (Common Era), an event dated for the first time along the Atlantic coast of Morocco. The other two layers, referred to as E13 and E14, were dated between 3464 and 2837 cal BP (calibrated years Before Present) and chronologically correlated with marine high-energy deposits found on the Spanish Atlantic coast. This correlation confirms the existence of another regional event around 3200 BP.
