Hydrological Trend Analysis Due to Land Use Changes at Langat River Basin
(2010) Juahir, Hafizan; Zain, Sharifuddin M.; Aris, Ahmad Zaharin; Yusof, Mohd Kamil; Samah, Mohd Armi Abu; Mokhtar, Mazlin Bin
"This 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. Trend analyses indicated that a relationship between hydrological parameters namely discharge and direct runoff and land use types namely agriculture, forest, urban, waterbody and others was evident. This analysis indicates that rainfall intensity does not play an important role as a pollutant contributor via the rainfall runoff process nor does it directly influence the peak discharges. Land use shows tremendous changes in trend surrounding Dengkil station compared a little changes surrounding Lui station. Mann-Kendall test of trend shows an increasing trend (p-value<0.01) of annual maximum-minimum ratio for Dengkil station, while no significant trend is observed for Lui station. There is evidence that regional variability in discharge behaviour is strongly related to land use or land cover changes along the river basin."
Impacts of Forest Changes on Indigenous People Livelihood in Pekan District, Pahang
(2010) Harun, Rosta; Sulong, Azizah; Wai, Yip Hin; Ismail, Tengku Hanidza; Yusof, Mohd Kamil; Manaf, Latifah Abdul; Juahir, Hafizan
"The forest cover change in the region due to timber extraction and change of land use pattern in the region have brought certain impacts on the livelihood of indigenous people. These people who once highly depended on the forest resources are the most affected. This study was done with the purpose to reveal the importance of forest as a source of their basic need and income for indigenous people and their future generation through the lens of history and place. A qualitative study had been done on the indigenous people that live in three villages in Pekan District, Pahang. Qualitative approach using face-to-face interview was applied to gather the oral history on the impacts of forest change at their place. It shown that forest change has much more impacts on the forest depended communities in the fringe of forests. A small tabletop recorder was used to record the interview session. This study could provide valuable inputs to government and other stakeholders on managing issues related to indigenous people, environment and their culture."
