Research ArticleOpen accessEvery word in the titleHyperspectral Remote Sensing for Tropical Rain ForestKamaruzaman Jusoff, Kasawani IbrahimProblem statement: Sensing, mapping and monitoring the rain forest in forested regions of the world, particularly the tropics, has attracted a great deal of attention in recent years as deforestation and forest degradation account for up to 30% of anthropogenic carbon emissions and are now included in climate change negotiations. Approach: We reviewed the potential for air and spaceborne hyperspectral … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,581 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Chemical Properties on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to investigate the seriousness of degradation of peat swamp forest caused by skidding system in terms of its function as a carbon sink. In this study, we formulated assumptions that conditions of our research site before the introduction of skidding system were in their natural states, thus that changes measured are clearly caused by skidding … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,919 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Precipitation Fluctuation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,606 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Converting Secondary Forest to Oil Palm Plantation on Peat Soil Carbon and Nitrogen and other Soil Chemical PropertiesMakilan Muniandy, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohd Khanif YusopProblem statement: Peatlands are natural sequesters of carbon and nitrogen. Once they are disturbed the tendency to lose carbon and nitrogen to the environment is very high. This study investigated the effect of converting peat land forest into oil palm plantation on soil chemical properties with particular emphasis on carbon and nitrogen storage. Approach: Soil samples were collected randomly at … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,308 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Hillside Gradient on Forest Road Cross Section Components in a Loamy Clay SoilAidin Parsakhoo, Seyed Ataollah Hosseini, Majid Lotfalian, Hamid JalilvandProblem statement: In this study to evaluate the effects of hillside gradient on forest road cross section components in a loamy clay soil the amount of cut and fill slopes gradient and length, road bed and earthwork width were taken on tangent sections in a lat talar forest roads of Iran. Approach: The objective of this study were: (i) to … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,994 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Different Ages of a Rehabilitated Forest on Selected Physico-chemical PropertiesRajeswari A.P. Murugayah, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: This research was important because of still lack of information about rehabilitated tropical forest age effect on infiltration rate. The objectives of this study were to determine the influence of age of forest on soil water infiltration rate and to evaluate the influence of forest age on the relationship between water infiltration rate, soil organic matter and soil … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,108 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVegetation Assessment of Peat Swamp Forest Using Remote SensingSeca Gandaseca, John Sabang, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Peat covers 1.6 million ha (13%) of the 12.4 million ha land area of Sarawak and some of peat swamp forests have been logged. The objective of this study was to assess the impact of logging operation on peat swamp forest in this area. Approach: The study used a remote sensing technique to assess vegetation cover in a … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 9,136 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Converting Secondary Forest on Tropical Peat Soil to Oil Palm Plantation on Carbon StorageCh’ng Huck Ywih, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Peat has been identified as one of the major groups of soils found in Malaysia. Sarawak as the largest state in Malaysia has the biggest reserve of peat-land. There are about 1.5 million ha of peat-land in Sarawak, which are relatively under developed. As is the case with any plant, oil palm trees do sequester carbon as they … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 9,048 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOrganic Matter, Carbon and Humic Acids in Rehabilitated and Secondary Forest SoilsLee Yit Leng, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem Statement: Tropical rainforests cover about 19.37 million ha (60%) of Malaysia’s total area and about 8.71 million ha can be found in Sarawak, Malaysia. Excessive logging, mining and shifting cultivation contribute to deforestation in Sarawak. The objectives of this study were to: (i) Quantify soil Organic Matter (SOM), Soil Organic Carbon (SOC) and Humic Acids (HA) in rehabilitated and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,767 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysical and Biological Responses of Forests to Tropical Cyclones Affecting the United States Atlantic Ocean and Gulf of Mexico CoastsKrista Merry, Pete Bettinger, Jeffrey HepinstallProblem Statement: Natural resources within the southern United States have repeatedly been subjected to the impact of tropical cyclones. While the frequency of tropical cyclones hitting either coast varies from year to year, it is crucial for natural resource managers and land owners to be prepared for the damage resulting from such storms.
