Agricultural and forestlands have been transformed into urban/built-up areas. This study analysed urban expansion and its relationship with the temperature of Accra from 1986 to 2022. Multi-source datasets such as remote sensing (RS) and other ancillary data were utilised. Land use land cover (LULC) maps were produced employing the random forests classifier. Land surface temperature (LST) and selected d(RS) Indices were extracted. Regression techniques assessed the interplay between LST and remote sensing indices. The LULC maps revealed increasing trends in the urban/built-up areas at the expense of the other LULC types. The analysis from the LST and the RS indices revealed a direct relationship between temperature and urban/built-up areas and an inverse relationship between temperature and vegetation. Thus, spatial urban expansion has modified the urban temperature of Accra. The integrated ut...

Unrestrained impetus of development and land use land cover change (LULCC) portent several issues such as unlawful urban sprawl, loss of agricultural land, forest loss and other associated complications. This study analyzed the dynamics of urbanization and other LULCC in Ghana's Greater Kumasi area via Landsat images (TM 1986, OLI 2013 and OLI 2023) using ERDAS Imagine, Idrisi and ArcGIS software. Implementing supervised classification technique, the Maximum Likelihood Classifier (MLC) procedure was employed to categories the study area into five LULC classes. Accuracy assessment undertaken on the resultant LULC maps was deemed very satisfactory. The results from 1986-2023 pointed to an upsurge in a built-up extent as of 8% to 41%, a decrease in Closed Forest from 9% to 4%, another decrease in Open Forests from 64% to 33%, a slight increase from 16% to 20% in farmlands and a stable level of water share. Further analysis indicated that the study area had undergone LULCC within the periods 1986-2013 and 2013-2023 at 60% and 37% respectively. The findings showed uncontrolled urban sprawling along major roads and forest loss as deforestation outside protected areas and degradation in protected forest. The monitoring of urbanization and other LULCC is important for local, and national governments and other bodies charged with the implementation of programs

This study assessed the past LULCC in the Atwima Nwabiagya which contains the Barekese and Owabi Headworks) and the old Kumasi Local Assemblies' areas in Ghana and projected the scenario in 2040 for business-as-usual (BAU). The synergies of satellite imagery of 1990, 2000, 2010 and 2020 were classified with an overall accuracy of 90%. Markov Cellular-Automata method was used to forecast the future LULC pattern after detecting main driving forces of LULCC. The findings showed an extensive increase in built up areas from 11% in 1990 to 39% in 2020 owing largely to 23% decrease in forest cover and 6% decrease in agricultural lands within the past 30 years (1990-2020). The projected LULC under the BAU scenario for 2040 showed built-up surge from 39% to 45% indicating additional forest loss from 43% in 2020 to 40% and decreasing agricultural land from 17% to 14%. The main driver for the LULCC is clearly anthropogenic driven as the human population in the study area keeps rising every censual year. This study exemplifies the fast-tracked forest loss, loss of arable land and challenges on ecosystem sustainability of the Barekese-Owabi-Kumasi landscape. The current and projected maps necessitate the apt implementation of suitable inter

Landsat satellite images for 1986, 2003, 2013, and 2022, covering the Kumasi Metropolitan Assembly and its adjoining municipalities, were used to analyse the Land Use Land Cover (LULC) changes. The machine learning algorithm, Support Vector Machine (SVM), was used for the satellite image classification that led to the generation of the LULC maps. The Normalised Difference Vegetation Index (NDVI) and Normalised Difference Built-up Index (NDBI) were analysed to assess the correlations between the indices. The image overlays of the forest and urban extents and the calculation of the annual deforestation rates were evaluated. The study revealed decreasing trends in forestlands, increased urban/built-up areas (similar to the image overlays), and a decline in agricultural lands. However, there was a negative relationship between the NDVI and NDBI. The re...

This study analysed temperature and trends in temperature in both cities using in-situ measurements from one meteorological station in both cities from 1986 to 2015. The temperature indices were computed using the RClimdex package from the Expert Team on Climate Change Detection Monitoring Indices (ETCCDMI). The temperature time series was pre-whitened before the Mann–Kendall trend and Sen’s slope estimator analysis were applied. Initial analysis revealed minimal variation in temperature in both cities. The results from the analysed temperature indices revealed an increase in warm days and a general rise in the minimum temperature compared to maximum temperatures. Mann Kendall and Sen’s slope revealed significant trends in the annual and seasonal (dry and wet seasons) in minimum temperature in both cities. These might lead to an increased rate of heat-stres...

Deforestation and conversion of forest land to agricultural land continue to be one of the major environmental problems in Africa, and for that matter, Ghana cannot be exceptional; and its resultant effect is the loss in the ecological integrity and the quality of forests, resulting in carbon loss and the resultant climate change effects (FAO 2016). The study area covers the Community Resource Management Areas (CREMA) of the Mole National Park in Ghana, and this study reveals that the area is well endowed with a diverse composition and structure of woodland including dense, open and riverine stretches, which – under the national definition of forest – qualifies as forest. The results reveal that there had been an annual deforestation rate of 0.11% over the period of review. It was concluded from the study that woodland had high carbon stocks with an average carbon of 80...

It is imperative to monitor land use change and to forecast forms of future land use change on a temporal and spatial basis. The main thrust of this study is to assess land use change in the lower half of the Ashanti Region of Ghana within a 40 year period. The analysis of land use change uses a combination method in Remote Sensing (RS) and Geographic Information System (GIS). Cellular Automata and Markov Chain (Cellular Automata-Markov) are utilized to predict for land use land cover (LULC) change for 2020 and 2030. The processes used include: (i) a data pre-processing (geometric corrections, radiometric corrections, subset creation and image enhancement) of epoch Landsat images acquired in 1990, 2000, and Disaster Monitoring Constellation (DMC) 2010; (ii) classification of multispectral imagery (iii) Change detection map...

In the past two centuries the impact of human activities on land has grown enormously, altering entire landscapes, and ultimately impacting the earth abiotic components (climatic and edaphic factors) and other biotic components. Land-use and land-cover changes are local and place specific, occurring incrementally in ways that often escape our attention. Yet collectively, they add up to one of the most important facets of global environmental change. This study used the techniques of satellite imagery (Landsat images) and GIS to analyze the extent of land use /cover and land change between the years 1986 - 2010 in Kumasi and its environs of Ghana. Within this twenty year interval, the images were analyzed by comparison and contrasting to ascertain how the lan...

There is a certain cause and effect relationship between changing practice for development and land use change, thus necessitating an assessment of land use dynamics and the projection trend. A combination of geospatial and remote techniques were utilized to evaluate the present and future landuse/ landcover scenario of southern part of the Western Region of Ghana. Multi-temporal satellite imageries of the Landsat series and DMC were used to map the changes in land use from 1990 to 2010. Four major land use classes (Forest, Agriculture, Built-up and water) were considered as the most dynamic land cover/use (LULC) practice. Markov modelling was applied for prediction of probable land use/ land cover change scenario for the years 2020, 2030 and 2040. The study showed that in years 2020 to 2040 in the predictable future, ther...

Studying the effects of past, present and future LULC on forest cover and other dynamic land uses provide valuable information for environmental, land planning and climate change mitigation measures. This study uses a combined methodology of Remote Sensing and Geographical Information System to map historical, current and future LULC through Satellite imagery (Landsat TM, Landsat ETM+, ALOS, Disaster Monitoring Constellation-DMC and SENTINEL) covering Greater Kumasi in a 40-year period. LULC classes such as Agriculture, Built-up, Close Forest, Open Forest, and water were considered based on the predominant geographical sceneries, remote sensing data and field study. Markov Cellular Automata modelling was employed for the estimation of likely LULC changes for the year 2040. The study discovered a perturbing development of forest loss (forest degradation and deforestation), decreasing agricultural activities whiles the Built-up share ballooned. Increasing urbanization at the expense of forest cover and transformation of agricultural lands into human settlements were observed. The forecasted LULC map for 2040 indicated an upward growth in Built up areas at the detriment of the other LULC categories. The outcomes validate the urgent necessity for critical review of regulations in LULC policy strategy, design, and development for the protection of forests and other critical ecosystem services to be preserved. This trend encompassing historical, current and future LULC necessitates that prudent resolutions have to be made to guarantee forest cover, make available land for agriculture and to mitigate the effects of the climate change

There is a certain cause and effect relationship between changing practice for development and land use change, thus necessitating an assessment of land use dynamics and the projection trend. A combination of geospatial and remote techniques were utilized to evaluate the present and future landuse/ landcover scenario of southern part of the Western Region of Ghana. Multi-temporal satellite imageries of the Landsat series and DMC were used to map the changes in land use from 1990 to 2010. Four major land use classes (Forest, Agriculture, Built-up and water) were considered as the most dynamic land cover/use (LULC) practice. Markov modelling was applied for prediction of probable land use/ land cover change scenario for the years 2020, 2030 and 2040. The study showed that in years 2020 to 2040 in the predictable future, ther...

In this region, the population is highly dependent on forestry products which represent a vital part of the economy. The effect of population growth on natural resource utilization studies is very profound. This study assesses land use change in the Ashanti Region of Ghana within a 25 year period. The analysis of land use change uses a combination method in Remote Sensing (RS) to explain the effect of population growth on natural resource. The procedures used include: (i) a data pre-processing (geometric corrections, radiometric corrections, subset creation and image enhancement) of epoch Landsat images acquired in 1986, 2007, and Disaster Monitoring Constellation (DMC) 2011; (ii) classification of multispectral imagery (iii) Change detection mapping. The results show a very grim picture of the extent of forest loss due to anthropogenic factors such as Agriculture and settlement. Populatio...

Studying the effects of past, present and future LULC on forest cover and other dynamic land uses provide valuable information for environmental, land planning and climate change mitigation measures. This study uses a combined methodology of Remote Sensing and Geographical Information System to map historical, current and future LULC through Satellite imagery (Landsat TM, Landsat ETM+, ALOS, Disaster Monitoring Constellation-DMC and SENTINEL) covering Greater Kumasi in a 40-year period. LULC classes such as Agriculture, Built-up, Close Forest, Open Forest, and water were considered based on the predominant geographical sceneries, remote sensing data and field study. Markov Cellular Automata modelling was employed for the estimation of likely LULC changes for the year 2040. The study discovered a perturbing development of forest loss (forest degradation and deforestation), decreasing agricultural activities whiles the Built-up share ballooned. Increasing urbanization at the expense of forest cover and transformation of agricultural lands into human settlements were observed. The forecasted LULC map for 2040 indicated an upward growth in Built up areas at the detriment of the other LULC categories. The outcomes validate the urgent necessity for critical review of regulations in LULC policy strategy, design, and development for the protection of forests and other critical ecosystem services to be preserved. This trend encompassing historical, current and future LULC necessitates that prudent resolutions have to be made to guarantee forest cover, make available land for agriculture and to mitigate the effects of the climate change

The study analyzed forest resource use trend, mapped out areas of high biodiversity conservation, and made recommendations to promote and sustain large-scale plantation development against the background of anthropogenic pressure on vulnerable ecosystems and biodiversity management. The methodology adopted for the study involved the application of geographic information system (GIS) and remote sensing techniques, field survey and community interactions. Major findings of the assessment include substantial land use/land cover conversion from one category to another within the past 20 years as a result of agricultural expansion, urbanisation, charcoal production and wood fuel harvesting; dense woodland and riverine forest experienced decline for the 20-year period whilst agriculture open woodland/grassland and settlement were ap...
