Item Embargo Spatial and statistical trend characteristics of rainfall erosivity (R) in upper catchment of Baram River, Borneo(Springer, 2019) H. Vijith; D. Dodge-WanThe upper catchment region of the Baram River in Sarawak (Malaysian Borneo) is undergoing severe land degradation due to soil erosion. Heavy rainfall with high erosive power has led to a number of soil erosion hotspots. The goal of the present study is to generate an understanding about the spatial characteristics of seasonal and annual rainfall erosivity (R), which not only control sediment delivery from the region but also determine the quantity of material potentially eroded.Item Embargo Soil erosion assessment and its correlation with landslide events using remote sensing data and GIS: a case study at Penang Island, Malaysia(Springer, 2012) Biswajeet Pradhan; Amruta Chaudhari; J. Adinarayana; Manfred F. BuchroithnerIn this paper, an attempt has been made to assess, prognosis and observe dynamism of soil erosion by universal soil loss equation (USLE) method at Penang Island, Malaysia. Multi-source (map-, space- and ground-based) datasets were used to obtain both static and dynamic factors of USLE, and an integrated analysis was carried out in raster format of GIS. A landslide location map was generated on the basis of image elements interpretation from aerial photos, satellite data and field observations and was used to validate soil erosion intensity in the study area.Item Embargo Sustainability of current agricultural practices in the Cameron Highlands, Malaysia(Springer, 2005) B. Y. Aminuddin; M. H. Ghulam; W. Y. Wan Abdullah; M. Zulkefli; R. B. SalamaA study on the sustainability of these agro-ecosystems was conducted. Results indicated that soil loss was in the range of 24-42 ton/ha/yr under vegetables and 1.3 ton under rain-shelter. Sediment load in the vegetable sub-catchment reached 3.5 g/L, 50 times higher than that associated with flowers under rain-shelter and tea. The sediments contained high nutrient loads of up to 470 kg N/ha/yr. The N, P and K lost in runoff from cabbage farms was 154 kg/season/ha, whereas in chrysanthemum farms it was 5 kg. In cabbage farms, the N, P, and K lost through leaching was 193 kg/season/ha. The NO3-N concentration in the runoff from the cabbage farms reached 25 ppm but less than 10 ppm in runoff from rain-shelters. Inorganic pollution in the rivers was within the acceptable limit of 10 ppm.Item Embargo Hydrological trend analysis due to land use changes at Langat river basin(Thai Society of Higher Eduation Institutes on Environment, 2010) Hafizan Juahir; Sharifuddin M. Zain; Ahmad Zaharin Aris; Mohd Kamil Yusof; Mohd Armi Abu Samah; Mazlin Bin MokhtarThis present study was carried out to detect the spatial and temporal change (1974-2000) in hydrological trend and its relationship to land use changes in the Langat River Basin. To obtain a clear picture of the hydrological parameters during the study period, rainfall data were analyzed. With the help of GIS and non-parametric Mann-Kendall (MK) statistical test the significance of trend in hydrological and land use time series was measured.Item Embargo Prediction of soil and nutrient losses in a highland catchment(Springer, 2005) Ghulam M. Hashim; W. Y. Wan AbdullahA simulation study using GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) was conducted at a catchment presently under tea farming in Cameron Highlands, Malaysia. Soil, water and nutrient transport associated with several alternative land uses was studied. In addition, the effect of a disruptive form of land clearing on soil, water and nutrient losses was also investigated. Modelling with GLEAMS required information from field measurements and observations, laboratory analyses, guide tables, industry records, maps and reports published by soil survey and meteorological departments.Item Embargo Effect of upstream on downstream due to spatio-temporal land use land cover changes in Kelantan, Peninsular Malaysia(Technoscience Publications, 2017) Mohd Talha Anees; Abdullah K; Nawawi M.N.M; Nik Norulaini Nik Ab Rahman,Abd.

In Malaysia, about 25% of the peatland area has been converted to oil palm plantation where drainage, compaction and groundwater table control are prerequisite. To date, relationship between land compaction and C emission from tropical peatland is scarcely studied. To understand the effect of compaction on soil carbon dioxide (CO2) and methane (CH4) flux from tropical peatland, a laboratory soil column incubation was conducted.Item Embargo Impacts of urbanization on mangrove forests and brachyuran crabs in Penang, Malaysia(Springer, 2021) Johann Stiepani; Lucy Gwen Gillis; Su Yin Chee; Martin Pfeiffer; Inga NordhausUrban development is driving the loss and subsequent fragmentation of mangrove forests in Penang, Malaysia. However, little research has focused on the implications of urbanization onto the biodiversity within mangrove forests. This study investigates and compares both vegetation and crab assemblages between urban and rural mangrove forests.Item Embargo Assessing changes of carbon stock in dipterocarp forest due to hydro-electric dam construction in Malaysia(Springer, 2021) Hayana Dullah; Marlinda Abdul Malek; Hamdan Omar; Sajjad Ali Mangi; Marlia Mohd HanafiahDeforestation and forest degradation are among the leading global concerns, as they could reduce the carbon sink and sequestration potential of the forest. The impoundment of Kenyir River, Hulu Terengganu, Malaysia, in 1985 due to the development of hydropower station has created a large area of water bodies following clearance of forested land. This study assessed the loss of forest carbon due to these activities within the period of 37 years, between 1972 and 2019.Item Embargo Land use change in highland area and its impact on river water quality: a review of case studies in Malaysia(Springer, 2018) Azlini Razali; Sharifah Norkhadijah Syed Ismail; Suriyani Awang; Sarva Mangala Praveena; Emilia Zainal AbidinThe continuous trend of river water quality deterioration in Cameron Highlands has raised the issues for discussion in this review article. The purpose of this review is to briefly summarize the land use change, agriculture practices, agro-tourism, and agriculture policy and management toward water quality of the river system network in Cameron Highlands specifically in the downtown where most of the development and agriculture activities are concentrated. A rigorous review has been done on the existing literature to determine the relationship between land use change and agriculture practices toward river water quality in Cameron Highlands from 2001 to 2017.Item Embargo Land Use/Land Cover Mapping for Conservation of UNESCO Global Geopark Using Object and Pixel-based Approaches(IOP Publishing, 2018) M K A Halim; A Ahmad; M Z A Rahman; Z M Amin; M F A Khanan; I A Musliman; W H W Kadir; M H Jamal; D S Maimunah; A K A Wahab; M M A Zabidi; N M Suaib; R M ZainThis study aims to map and evaluate digital classification methods of mapping of LULC using Very High Resolution (VHR) Quickbird satellite imagery in one of the Langkawi UNESCO Global Geopark, that is Kilim Karst Geoforest Park (KKGP) which is located at northeast of Langkawi, Kedah, Malaysia. Object-based and pixel-based classification methods were explored and compared. Object-based method involved multi-resolution segmentation part where scale parameter, shape and compactness should be assigned as accurate as possible, so that the image is segmented to homogenous area. Both segmentation and classification processes were conducted in e-Cognition software. While, a supervised classification, Maximum Likelihood Classification (MLC) involved selection of training areas was used for pixel-based method using ERDAS Imagine software. Then, classification accuracies were assessed by comparing both techniques using error matric and Kappa coefficient.Item Embargo Land use/land cover changes and the relationship with land surface temperature using landsat and MODIS imageries in Cameron Highlands, Malaysia(Multidisciplinary Digital Publishing Institute (MDPI), 2020) Darren How Jin Aik; Mohd Hasmadi Ismail; Farrah Melissa MuharamMountainous regions are more sensitive to climatic condition changes and are susceptible to recent increases in temperature. Due to urbanization and land use/land cover (LULC) issues, Cameron Highlands has been impacted by rising land surface temperature (LST) variation. Thus, this study was carried out to explore the impact of the LULC change on LST in the Cameron Highlands from 2009 to 2019 using remote sensing images acquired from Landsat 7 ETM+, Landsat 8 Operational Land Imager (OLI/TIRS), and Moderate Resolution Imaging Spectroradiometer (MODIS) 11A Thermal sensors.Item Embargo Impact of land uses on water quality in Malaysia: a review(Springer, 2019) Moriken Camara; Nor Rohaizah Jamil; Ahmad Fikri Bin AbdullahLand use changes in urbanization, industrialization, and agricultural processes will continue to have negative impacts on water quality at all scales. The impact of land use changes on water quality is generally studied by analyzing the relationships between land use and water quality indicators. Therefore, the purpose of this research was to review and analyze the main relationships between land use and water quality, as well as to visualize the major sources and processes of water quality pollution in Malaysia.Item Embargo Conservation of Sarawak peat swamp in an urban landscape by fuzzy inference system(Springer, 2011) Darrien Yau Seng MahFreshwater habitats are one of the planet’s most important, yet most manipulated, environments. This is what happens in Sarawak that the environment has been radically changed due to urban developments. This paper is promoting the idea that we do not need a complicated but a simple tool like fuzzy inference system to strike a balance between the existence of peat swamp and the humans who live nearer and nearer to it.Item Embargo From Forest Landscape to Agricultural Landscape in the Developing Tropical Country of Malaysia: Pattern, Process, and Their Significance on Policy(Springer, 2008) Saiful Arif Abdullah; Adnan A. HezriThis paper examines: (i) the links between development policies and changes in land use/land cover and landscape pattern and (ii) the significance and implications of these links for future development policies. The objective is to generate insights on the changing process of land use/land cover and landscape pattern as a functional response to development policies and their consequences for environmental conditions.Item Embargo Impact assessment of rapid development on land use changes in coastal areas; case of Kuala Langat district, Malaysia(Springer, 2015) Sharareh Pourebrahim; Mehrdad Hadipour; Mazlin Bin MokhtarThe first large urban conurbation in Malaysia stretching from the central mountain spine to the west coast has expanded all rounds to emerge as a potential mega-urban region. It covers the area from the Bernam River basin in south Perak to the Linggi River basin in Negri Sembilan. The analysis of the land use change patterns and the prediction of future changes can highlight the problems of continuing current pattern of growth. Kuala Langat as the case study is located in the strategic area, because this area is identified as a Klang Valley II.Item Embargo Sustainable use of tropical forests by reduced-impact logging in Deramakot Forest Reserve, Sabah, Malaysia(Springer, 2007) Peter Lagan; Sam Mannan; Hisashi MatsubayashiIn pursuance of economic growth and development, logging has exhausted the natural timber resource in the tropical rainforest of Sabah, Malaysia. Realizing the forest depletion, the Sabah Forestry Department, with technical support from the German Agency for Technical Cooperation, begun developing a management system with the intent of managing all commercial forest reserves in a way that mimics natural processes for sustainable production of low volume, high quality, and high priced timber products in 1989. As dictated by a forest management plan based on forest zoning, about 51,000 ha of the entire area is set aside for log production and 4,000 ha for conservation in Deramakot Forest Reserve, Sabah, Malaysia.Item Embargo Impacts of logging road networks on dung beetles and small mammals in a Malaysian production forest: Implications for biodiversity safeguards(Multidisciplinary Digital Publishing Institute (MDPI), 2014) Toshihiro Yamada; Masahiro Niino; Satoru Yoshida; Tetsuro Hosaka; Toshinori OkudaWe conducted research on the impact of logging on biodiversity of dung beetles and small mammals in a production forest in Temengor Forest Reserve, Perak, Malaysia. This was done to develop such quantitative criteria for Malaysian production forests while paying special attention to the effects of road networks, such as skid trails, logging roads, and log yards, on biodiversity.
