The rapid urbanization, industrialization, agricultural activities, and increasing trend of some natural hazards, such as climate change, particularly in coastal areas, necessitate the continual assessment of critical but fragile ecosystems like that of the Keta Lagoon Complex Ramsar Site (KLCRS). This productive ecosystem in Ghana faces serious threats from intensive exploitation, physical modification, changes in water regime, and water pollution. The current study employed geospatial and intensity analysis to assess the pattern of land use/land cover (LULC) change for almost the past three decades and morphometric parameters of the KLCRS landscape. Landsat Satellite images for 1991, 2007, and 2020 were acquired to uncover the pattern of LULC change, while morphometric changes were assessed using global Advance Space Thermal Emission and Radiometer (ASTER) digital elevation model (DEM) data and the spatial analyst tools in GIS software. The result established that the acceleration of land transformation was intensive between 2007 and 2020, which could be linked to population growth and increased socio-economic activities. There was a net gross gain of built-up that originated largely from the conversion of marsh, dense vegetation, and cultivated land. Prior to this period, cultivated land recorded net gain (125.51 km2) between 1991 and 2007, whereas dense vegetation and marshland showed a net loss of 151.37 km2 and 2.44 km2, respectively. The gain of cultivated land largely targeted marshland in both time intervals. The construction of saltpans contributed largely to the small increase in water extent. The morphometric analysis revealed the groundwater potential of the KLCRS. The low-lying nature of the landscape makes the area susceptible to coastal flooding. The trend of the observed changes could invariably affect the ecological integrity of the landscape, hence suggesting the need for immediate preparation and implementation of marine and coastal spatial plans by relevant stakeholders.

“…For example, the water table of the Mitidja of a reservoir of 2 billion m 3 of water of very good quality. Today, exploited at more than 90% of its capacity, the water table of the Mitidja is polluted by nitrates [19,20]. Threatened from a quantitative and qualitative point of view, the water table of Mitidja is no longer able to meet the demand for irrigation and drinking water supply.…”

In Algeria the plain of Mitidja, famous for the fertilization of its soil, on overuse, is exposed to pollution due particularly to fertilizers and other phytosanitary. The spatio-temporal distribution of the concentrations of major ions, namely nitrates, would explain the transfer and circulation mechanisms of these elements within groundwater .The disparity in nitrate levels shows exposure of the Mitidja aquifer to pollution over its entire extent. The geological origin of the high concentrations of nitrates in places cannot alone explain this distribution. The levels are higher during recharge and irrigation due to the leaching effect of agricultural soils. The use of highly nitrogenous chemical fertilizers in agriculture, compared to the evolution of piezometric levels, causes a significant increase in nitrate concentrations due to their transport from the surface to the aquifer. The subterranean waters of the Quaternary aquifer in the Mitidja show in certain areas concentrations greater than 250 mg / l (Hamiz region in the eastern part of the Mitidja). This high concentration results mainly from irrigation (market gardening).
