“…They are also reproducible tools that supplement our existing capabilities to analyse land use change and to make more informed decisions (Costanza and Ruth 1998). Such models rely on Geographic Information Systems (GIS) and satellite remote sensing techniques which can be effectively applied to detect LULC changes in urban expansion (López et al 2001;Prenzel 2004;Weng et al 2003), urban planning (Li and Yeh 1998), as well as in cropland and forest loss (Li and Yeh 2004).…”

Urban population growth has been accelerating in the developing countries and this exerts tremendous pressure on available land resources in major cities and urban centres. Greater Doha, which is a metropolis area where 78% of the country's population live, has witnessed a substantial population growth and a large urban expansion. This study is the first of its kind in the State of Qatar and it aims to provide an understanding of the land use/land cover (LULC) change and its spatiotemporal pattern in Greater Doha between the years 1997 and 2010. Parcel data and census statistics from these two dates were used in the analysis. LULC change statistics indicate a very large increase of 289% in the built-up areas and a larger increase of 426% of recreational spaces which shows a progressive planning approach towards improving living standards in Greater Doha. As a result of this development demands, the open spaces have been substantially reduced from 77% to 25%, population density increased in many parts of the metropolis and high-rise building started to dominate the skylines in certain parts of the metropolis. MARKOV model was used to generate future LULC change scenarios for the year 2020. The analysis predicts a 20% increase of built-up areas which will take place in the open spaces, and this modest increase may be explained by model constraints resulting from limited availability of land within the current boundaries of Greater Doha for future development.

“…Satellite remote sensing had been widely applied on detecting LULC change [7, 40, 15, 24, 25, 48, 41, 42, 43, 44] especially urban expansion [39, 45, 34, 41, 42, 43, 44, 28], urban planning [49] and cropland loss [43, 27, 31]. Many change detection techniques, which was the process of identifying differences in the state of and object or phenomenon by observing it at different times [18, 38], were used in these studies, such as image differencing, vegetation index differencing, selective principal components analysis, direct multi-date classification, univariate image differencing, image rationing, change vector analysis and post-classification and so on [29, 38, 1].…”

“…Among these studies, systematical and profound works were finished by Li, Yeh, Weng, Kaufmann and Seto mainly. Their researches discussed LULC changes of this area based on different point of views, and the time range of research was very wide, from 1978 to 1997 [26, 42, 44, 21, 35, 36]. Their studies were all based on the classification results of one scene image rather than the subset images, and took 5 years as a research cycle to discuss land use change.…”

Land use and land cover change is a major issue in global environment change, and is especially significant in rapidly developing regions in the world. With its economic development, population growth, and urbanization, Guangzhou, a major metropolitan in South China, have experienced a dramatic land use and land cover (LULC) change over the past 30 years. Fast LULC change have resulted in degradation of its ecosystems and affected adversely the environment. It is urgently needed to monitor its LULC changes and to analyses the consequences of these changes in order to provide information for policymakers to support sustainable development. This study employed two Landsat TM/ETM+ images in the dry season to detect LULC patterns in 1998 and 2003, and to examine LULC changes during the period from 1998 to 2003. The type, rate, and pattern of the changes among five counties of Guangzhou Municipality were analyzed in details by postclassification method. LULC conversion matrix was produced for each county in order to explore and explain the urban expansion and cropland loss, the most significant types of LULC change. Land use conversion matrixes of five counties were discussed respectively in order to explore and explain the inherence of land use change. The results showed that urban expansion in these five counties kept an even rate of increase, while substantial amount of cropland vanished during the period. It is also noted that the conversion between Sensors 2007, 7 1324 cropland and orchard land was intensive. Forest land became the main source of new croplands.

“…The main focus was the effects of these regional and global changes on society and the environment. Empirical studies by researchers from diverse disciplines indicated that land use /land cover and its change had become key to many area of study such as environmental science, geography, forestry, hydrology, agriculture, geology and ecology (Weng et al,2003). These various applications are known to the urban explosion, deforestation, water quality change, soil degradation, etc.…”

“…Eventhough, together with the positive changes especially those that made land more productive, there were also unforeseen impacts that could reduce the availability of land to sustain the human enterprise.

Rapid urbanization has been considerd one of the significant factor of urban studies in developing countries of the world since the emergence of population explosion in the 1960s and 1970s in larger cities (Barros, 2004). Land use/land cover change information is very essential in decision making process in urban planning implementation and management of urban areas to meet the increasing demands for basic human needs and welfare of the contemporary rapidly growing population. This paper is primarily focused on the changes occurred in landuse /land cover in Maiduguri urban area between 2000 and 2018. The study was conducted using Remote Sensing and GIS techniques. Landsat images of the Maiduguri Urban area for 2000 and 2018 were obtained and used for the study. Results from the study indicated that built-up area expanded from 51.81% in 2000 to about 64.57% in 2018, whereas agricultural area decreased by (-4.98kmsq), bear surface by (-2.57kmsq) and grassland by (-11.48kmsq) respectively. The study noted that changes in land use and land cover could be an essential tool for monitoring urban activities and resolving the negative consequences of urban growth. It is recommended that special priority should be given to urban growth and continuous investigations are required for effective urban development and management of the study area.
