In this study, the position of land suitability evaluation in Malaysia within the time frame of last ten years (2005 till date) wasreviewed from the view point of methods and applications. Although there had been some useful works done, no research had been done with a view of informing the research community on the development in this aspect. The...

... available land mass remain fixed against population growth and infrastructural development. According to Malaysia historical population (1960 -2015)data published on the 1st of January, 2015 (http://countrymeters.info/en/Malaysia), the country has a population of 8 160 975and an estimated population of 30 644 293in 1960 and 2015 respectively (see Fig. 1), while the total land area remains 329,847 square kilometers. This implies that in 1960 an individual can have access to about 40417 square meters in 1960 compared to 10764 square meters in 2015. So, within the last six decades, it means that access to land by individual have reduced by 73 per ...

... An increased economic return is required to meet the growing world population's economic demands. Unfortunately, the available landmass remains fixed, but the population growth and infrastructural development keep increasing (Ahmed et al., 2015). This increased pressure on the available land resources results in land degradation (Ahmed et al., 2016;Li et al., 2017). ...
Agricultural development in any region needs knowledge about the soils, their properties, and spatial distribution. Crop-land maps created using land evaluation are essential for land management. The research was conducted to develop a crop-land suitability map with “Highly Suitable”, “Moderately Suitable” and “Currently Not Suitable” categories for Karachchi Divisional Secretarial Division (DSD) (438.2 square kilometers) by analyzing soil quality. Twelve parameters and 63 sample locations were selected. Weather data such as rainfall, temperature, and relative humidity were collected from secondary sources. A slope map was created using the Digital Elevation Model (DEM) file, and the constructed questionnaire was used to obtain the drainage details. Soil depth was deduced from the wells and soil pits. The collected soil samples were analyzed to determine the parameters such as pH, electric conductivity, the sum of basic cations, base saturation, soil texture, and organic carbon. Each parameter was reclassified using ArcGISTM 10.4.1 to create parameter maps. After that, an analytical hierarchical process (AHP) was applied to each crop, and then each parameter was reclassified again with reference to FAO’s 1993 crop requirement criteria. Finally, the Weighted Overlay Analysis (WOA) was conducted to obtain the crop-land suitability map. The study revealed that 50% of the study area falls under the “Highly Suitable” category for coconut cultivation. Rain-fed paddy shows that 45% of the study area is “Moderately Suitable”. Irrigated paddy has a “Moderately Suitable” area of 48%, while nearly 51% is “Moderately Suitable” for onion. 17% of the land is “Highly Suitable” for groundnuts. The pineapple is “Highly Suitable” for 12% of the study area. A crop-land suitability map for Karachchi DSD was created. This map will be a guide for land planning decision-makers.
... It is characterized with two major seasons -wet and dry season [1]. The wet season is usually between the months of May and September while the dry months includes October to March , The district comprises of eight sub-administrative units called Mukims with a total population of 536147 people according to Malaysia statistics record [2].The mukims are Lenggeng, Setul, Pantai, Labu, Seremban, Rantau, Rasah and Ampangan. The main occupation of the people is agriculture dealing in rubber farming, oil palm, coconut plant [3]. ...
... The factor (K) which represents Soil erodibility put an emphasis on measuring the features of soil type and its resilience to dislodging and flooding due to rainfall. Figure 4 presents the factor K extracted from diverse soil series of the region of Seremban [2]. Each soil type's K factor is determined to identify its chemical and physical features, which plays a vital role in contributing to the potential of erosion. ...

Runoff causes soil loss and is a continuous ecological problem in Seremban, Malaysia. It is crucial to collect data on soil loss for improved agricultural productivity and to manage natural resources effectively. This research maps the distribution and estimates the yearly mean value of soil erosion through the utilization of techniques of remote sensing and GIS by implementing the Revised Universal Soil Equation (RUSLE). To determine the variables of RUSLE's soil loss and analyze them in an integrated GIS environment, we used a scale of 1:50,000 according to criteria of topographic map, Aster Digital Elevation Model (DEM) which has a feature of spatial resolution that extends up to 20 m, a soil map which is digitally programmed with a scale of 1:250,000, and a decade of rainfall records for 12 stations. The data revealed that Seremban records an annual soil loss that ranges from no soil loss in forested areas (Lenggeng - Panti - Ampangan - Seremban) to >100 tone hectare per year in the open area ((Labu - Renggam - Lenggeng). The total annual soil loss is estimated at 883 tonnes/hectare/year and is distributed across different land cover as follows: 198 tonnes from agriculture areas, 39 tonnes from forest areas, and 20.45 from rural areas, 610 tonnes from open area, 12 tonnes from urban areas, and 1.4 tonnes from inland water areas.
