“…Statistics is a branch of data modelling and analytical studies. Statistics are deemed to be the best approach to have in order to avoid misinterpretation of large, complex environmental monitoring data like those used in this study [ [67] , [68] , [69] , [70] ]. Statistical techniques are also being used to explore the data analysis tools for the classification of samples or sampling stations and the identification of pollution sources [ 71 ].…”

“…This study shows that forestland has decreased considerably (by 8.13%), mainly converted into cropland and human settlement from 2000 to 2020. Although many planning documents have formulated Selangor’s strategic policy to guide and coordinate sustainable urban development ( https://www.selangor.gov.my ), the data shows that people still develop the economic at the expense of green space 55 . For example, forestland have been cut down mainly in Sabak Bernam, Kuala Selangor, Hulu Langat and Kuala Langat for housing and cropland from 2000 to 2020 (Fig.…”

Rapid urbanization will cause various land use changes and the vast occupation of green spaces, a critical factor in the deterioration of biodiversity in urbanized areas. Some species of wildlife are endangered due to habitat shrunk and fragmentation. However, Malaysia's current biodiversity protection range is still limited. The Ecological Network (EN) refers to a framework of ecological components, which can be obtained by geographical and technical approaches to support more ecological diversity ranges. Furthermore, little research has been found on EN in Malaysia and the impact of land use change on EN. Therefore, the Selangor region is selected as the study area. This paper quantifies land use change and measures the extent of land use change to obtain the EN’s change. The result has shown that forestland has decreased, explored by people for housing and agriculture from 2000 to 2020. The EN has a trend of fragmentation. Overall, this study's results imply that the land use change led to EN's worsened performance from 2000 to 2020 in the study area. This paper hopes that this research could help supply information on conserving biodiversity in future development and urban sustainable planning in Malaysia.

“…Analysis was done on the spatial-temporal changes that occurred in agricultural lands as well as Malaysia's forests among 1990 and 2017. The findings revealed a 441 Mha, or 21%, decline in Malaysia's natural forests (7) .

Objective: This study investigates the Spatial temporal changes of LULC in Mathura district of Uttar Pradesh, India, over the past 30 years (1990 to 2020). The study uses Landsat-5, Landsat-7 as well as Landsat-8 OLI images and GIS technique. Methods: The images are classified into LULC classes using a random forest classifier. The LULC changes are analyzed using a change detection analysis. The results of the change detection analysis were visualized using GIS. Confusion matrix is used for comparing the Crop classification during 1990-2020. User accuracy, consumer accuracy, producer accuracy, overall accuracy and kappa coefficient are used to compare the study of approximately three decades from 1990 to 2020. Findings: The classification of LULC is done into six classes i.e., urban, water bodies, vegetation, wheat, mustard and other crops. The results show that there are significant changes in LULC over the past 30 years. In the year 1990, 70.1 % accuracy and kappa 61.61 are obtained. In the year 2000, 70.8 % accuracy and kappa 63.02 are obtained. In the year 2010, 71.3% accuracy and kappa 64.8 is obtained. In the year 2020, 84% accuracy and kappa 80 are obtained. Novelty: In traditional mapping is not feasible, multi temporal satellite imagery can offer the crucial measurement of spatial and temporal phenomena for the research area. The study shows that the predominant land use in the area under investigation is vegetation. Less agricultural activity occurred between 2000 and 2010, which increased the amount of land covered by vegetation. The importance of monitoring LULC changes in order to understand the effects of these variations on the society as well as environment.
