“…To detect the extent, type, and pattern of the land cover from 2008 to 2020, the research region's images were overlaid in ArcGIS to identify changes caused by the classification of the land cover. The acquired values were converted into percentages and utilized as absolute data to illustrate changes in land cover and use and to determine the rate at which these changes happened between 2008 and 2020 [26,27].…”

Deforestation, the widespread clearance of forests for various land uses, has become a significant global environmental issue with far-reaching consequences. Deforestation in the study area was identified, categorized, assessed, and interpreted using Landsat 5, 7, and 8 from the years 2008, 2014, and 2020, respectively. A geographic information system (GIS) database of land use and land cover categories and their changes were created. The results showed that several anthropogenic human activities, including agriculture and wood harvesting, were driving a general retreat of the forest area. The study further shows that between 2008 and 2020, forest area decreased by 8.5% with an annual rate of 0.33%, other vegetative areas increased by 2% with an annual rate of 0.077%, and non-vegetative areas increased by 1.5% with an annual rate of 0.58%. The hotspot map shows that the rate at which the reserve is deteriorating and the conversion of the forest area to other vegetation and bare ground are only a matter of time. The study recommended that the government should adopt rigorous policies to protect forest reserves from unauthorized habitation by encouraging the use of alternative firewood fuel sources to reduce the pressure on the forest.

“…An increase in population leads to land shortage and to meet the exponential demand for space and land, numerous land reclamation projects have been implemented (Jiang et al, 2021). A number of coastal nations, such as the USA, Netherlands, Japan, and Nigeria, have engaged in extensive sea enclosing and reclamation for urban expansion and industrial activities (Kida et al, 2021;Gyawali et al, 2021;Baker, 2022;Fashae et al, 2022).…”

The aim of this study was to investigate the impact of anthropogenic stressors on environmental variables, sediment properties and benthic macroinvertebrate assemblages of Lagos Lagoon. Four sampling stations were established with respect to their importance/ anthropogenic activities within Lagos Lagoon. Surface water, bottom substrates and benthic macroinvertebrate fauna samples were collected at all sampling stations for a year while samples were analyzed using appropriate standard methods and procedures. The highest pH ranged of 7.96–8.01 (7.98 ± 2.35) was recorded at Site IV while the lowest pH mean value of 6.15 ± 1.14 was observed at Site II. Seasonally, the highest values of temperature, electrical conductivity, nitrate and THB (38.10 ± 3.66°C, 61842.83 ± 11777.45 µs/cm, 6.09 ± 3.70 mg/L and 38174.83 ± 79509.21 cfu/ml) were observed at Site I during dry season. The highest sediment pH ranged of 6.18–9.18 (7.58 ± 0.27 mV/pH) for sediment was recorded at Site I while the lowest mean pH was observed at Site II (6.87 ± 0.19 mV). The mean of sulphate, lead, chromium, cadmium and total coliform counts were higher at Site II during the dry season while nickel was higher in the rainy season. A total number of 26 species of benthic macroinvertebrates were observed during the period of study belonging to 8 classes namely: grastropoda (11), polychaeta (7), malacostraca (3), bivalvia (2), clitellata (1), thecostraca (1) and insecta (1). Gastropoda recorded highest percentage contribution of 39.12% followed by Polychaeta accounting for 30.34%, while Malacostraca contribution was 2.63%. High abundance of macroinvertebrates was recorded at Site I (256 Indiv/m2) followed by Site IV (252 Indiv/m2) and least abundance was observed at Site II (195 Indiv/m2). Low macrobenthos recorded in this study could be due to high tolerate of physico-chemical changes. The encroaching into aquatic environment around the globe often introduce toxic chemicals into waterbodies which has led to loss of certain organisms, destabilization of sediments, and thriving of tolerant benthic macroinvertebrates. Concerned authority should pass a law to stop encroaching into aquatic environment for land reclamation as a result of high urbanization around the world.

“…An increase in population leads to land shortage, and numerous land reclamation projects have been implemented to meet the exponential demand for space and land [ 3 ]. Several coastal nations, such as the USA, Netherlands, Japan, and Nigeria, have been engaged in extensive sea enclosing and reclamation for urban expansion and industrial activities [ [4] , [5] , [6] , [7] ]. In Nigeria, the world’s most populous African nation with 202 million people, about 25% of the population lives in the seven coastal states, Lagos, Ondo, Delta, Bayelsa, Rivers, Akwa Ibom, and Cross Rivers, bordering the Atlantic Ocean [ 8 ].…”
