“…In the same Osun State, Adeoye and Dami (2012) observed human modification in terms of the reduction in the size of the original wetlands in Ile Ife. Similar findings were made by Abiodun and Akinola (2019), who investigated land use area and percentage of land use area in Osun State between 1986 and 2016.…”

Southwestern Nigeria's wetlands are assaulted, degraded, and lost, especially to agricultural development and urban expansions, while the rural wetlands losses are due to agriculture but temporal in nature, loss to urban developments are permanent. To examine the extent, influence, and potential of the degradation, the review covered the six states of the region, revealing losses due to wetlands destruction in the region between 1965 and 2019. Wetlands in Lagos reduced from 708.96ha (52.68%) in 1965 to 7.10ha (0.53%) in 2005, Eleyele Wetland in Oyo State, (Riparian), reduced consistently from (1.25 km2) in 1984 to (0.98 km2) 1994, (0.70 km2) 2004 and finally (0.42 km2) in 2014. Eriti forested wetlands of Ogun State lost about 45.32% between 1972 and 2015; in Ondo State, Akure South Local Government Area Wetlands decreased from 98.90 km2 (30.13%) in 1999 to 90.33 km2 in 2009 (27.52%); Ilesa wetlands, in Osun State decreased from 258 hectares to 89 hectares between 1986 and 2002. The above scenarios in the region imply that in a short while, the wetlands would be completely lost, most importantly to the uncontrolled urban developments. Therefore, there is an urgent need for all hands to be on deck to protect wetlands by considering them as endangered ecosystems.

“…The region has experienced substantial urban development, migration, and anthropogenic activities, leading to transformations in land use and cover [15,16]. Despite numerous studies on Osogbo metropolis, such as those by Aguda and Adegboyega (2013), Ebehikhalu et al [15] Emmanuel et al [17] and Abiodun and Akinola [18] gaps persist, necessitating continuous research to fill them. Aguda and Adegboyega (2013) highlighted changing land surface patterns but did not delve into land transition (Aguda and Adegboyega, 2013).…”

“…Aguda and Adegboyega (2013) highlighted changing land surface patterns but did not delve into land transition (Aguda and Adegboyega, 2013). Emmanuel et al (2019) explored thermal effects but lacked a comprehensive evaluation of land use and cover trends [17,18] discussed urban expansion impacts without specifying effects on the entire ecosystem [18,13] analyzed land use dynamics but overlooked influencing factors [13,12]. These knowledge gaps underscore the need for ongoing research to develop innovative methods for acquiring information on land use and cover transitions, predicting future changes, assessing terrain modifications, and understanding subsequent effects in Osogbo metropolis [19,20,21] Continuous geospatial studies on land use and cover transitions are critical as they serve as reference points for assessing changes and impacts [22].…”

Continuous Geospatial studies of the transitions in Landuse and landcover are very important especially as it relates to baseline assessment as an approach for advising in policy formulations concerning the natural resources sector. This study aimed at mapping and modeling the urban landscape of Osogbo metropolis, Osun state Nigeria, using an artificial neural network with the view of providing a framework for sustainable development and as well as generating data on Landuse and landcover change transitions and maps for planning purposes. Its objectives are to; model and analyze Landuse and landcover changes in Osogbo metropolis for the last 30 years (1990 – 2020) using an artificial neural network; ascertain the trend, and characteristics of Landuse and landcover changes in Osogbo metropolis in the last 30 years; assess the urban landscape change across various terrain configurations with Osogbo Metropolis over the last 30 years, and predict the future urban landscape of Osogbo Metropolis in 2040 using artificial neural network. The methodology involved data acquisition of Landsat, Sentinel-2, and ALOS Palsar images, image preprocessing to correct the scan line error in Landsat 7 ETM+, development of classification scheme, identification of class features and image classification, trend analysis, land cover/land use transition, and prediction to 2040. The assessment of landcover/landuse change revealed significant LULC changes in the studied area. Over 30 years (1990–2020), the built-up area classes increased significantly by 111.97 km2, while vegetation, open space, and water body decreased by 189.33 km2, 7.26 km2, and 3.46 km2 respectively. In terms of increased built-up area, this is largely seen in flat and undulating terrains between 281m and 341m. According to the prediction, by 2040, built up area is expected to grow from 35.89 % to 64.48 % covering an area of 201.2 km2, water body is expected to decrease from 1.11 % to 1.07 % with an area of 3.33 km2, vegetation is expected to decrease from 60.68 % to 32.42 % with an area of 101.15 km2, open space is expected to decrease from 2.33 % to 2.03 % to an area of 6.34 km2. The study´s annual rate of change results is recommended as it reveals the annual decline vegetation within the study area, as a direct consequence can lead to an increase in urban heat islands within the study area.

This paper attempts to disclose the law of land use variation in the Northeast China Tiger and Leopard National Park (NCTLNP), and provide theoretical basis for eco-environment protection of the national park in future. The data on land use variation in four phases (i.e., 1995, 2005, 2015, and 2018) were selected for analysis based on the geographical information system (GIS). The variation and transfer features of land use were quantified, with the aid of single land use dynamic degree, comprehensive land use dynamic degree, and land use transfer matrix. The results show that: (1) In 1995-2008, the main land types in the NCTLNP were forest, grassland, and cultivated land, which took up more than 90% of the total area; the grassland area increased, while the areas of cultivated land and forest declined; forest was the land use with the largest transfer-out area (523.59 km2), about 55.29% of the total transfer-out area in the study area; (2) In the sample period, NCTLNP witnessed significant transfers between land uses; the transfers mostly occurred between forest, grassland, and cultivated land; forest transfers were observed in every county and city; the transfer of forest to grassland mainly concentrated in Dongning City. The research results lay the basis for building up a stereo eco-environment monitoring network in the study area, and provide the research direction for eco-environment protection in the NCTLNP.
