The unsaponifiable fraction was identified by GLC. A series of hydrocarbons ranging from C 14-C 28 in addition to cholesterol, stigmasterol and the triterpenoids α and β-amyrin were ...

Mangrove ecosystem and its biodiversity are threatened due to climate change. Sundarbans mangrove ecoregion situated in Bangladesh (~62%) and India (~38%) is a bioclimatic zone. Sundarbans is one of the largest reserves for the Bengal tiger (Panthera tigris tigris L) which is the top predator. Therefore, it helps to regulate the number and distribution of prey, which in turn impacts forest structure, composition and regeneration. As climate change affects the flora and fauna in this ecosystem, these may be impaired because of migration of the species. The tigers become stray from forests to human inhabitants and causes tiger human conflicts which often results in retaliatory killings of tiger and human and or livestock. Therefore, the main objective of this study is to identify the effects of climate change towards the salinity intrusion and biodiversity, modification of floral and faunal composition, habitat loss and behavioral change of wildlife, which ultimately identify the factors for accelerating tiger human conflicts. It reviewed related literature through various websites and the secondary data were quoted with necessary modification. The primary data obtained from the office records of Bangladesh Forest Department and a social surveying was conducted on livelihood profile of the people living surrounding the Sundarbans to identify the relations between tiger attacking and their livelihood and living style. We used ArcGIS 9.3 to visualize the tiger habitat and trigger up the causes of root of conflicts between human and tiger. The results reveal the climate change effects in the Sundarbans Mangrove forest through changing its biodiversity composition in terms of loss of wildlife habitats which is responsible for accelerating tiger human conflicts. It suggests, a social and cultural revolution for sustainable alternative livelihood of forest-dependent population i.e., Alternative Income Generation (AIG), modification of the formal legal system, institutional development and in depth research can minimize these issues towards the sustainability of Sundarbans mangrove forest.

A one way ANOVA, followed by DMRT analysis were used to analyze the effects of the rate of changes between the parameters and the interrelations among them. Results showed that variation exists in the water quality parameters examined, with such parameters as temperature, transparency, pH, conductivity, dissolved oxygen, total dissolved solids, nitrite nitrogen, alkalinity, total hardness, conductivity falling within the approved standard concentration for fish survival with slightly higher concentration exists in ammonia and chloride in both the beels whereas carbon di oxide and turbidity in Kumari beel. Most of the parameters were also strongly correlated with one another. Highly positive correlation was found between temperature with pH and hardness, nitrite nitrogen with ammonia and turbidity, pH with alkalinity and hardness, turbidity with ammonia, total dissolved solids with transparency and conductivity, and highly negative correlation between conductivity with transparency in Hilna beel whether in Kumari beel highly positive correlation was found between temperature with carbon di oxide and turbidity with ammonia and conductivity and highly negative correlation found between temperature with pH.

An Integrated River Basin Management has been inaugurated in the Langat River Basin as part of IWRM implementation through newly formed Selangor Water Management Authority (LUAS) in 1999. This paper critically reviewed the scientific, management and evaluation literatures and reports on water resources management of this river catchment area. The study denotes, although a significant development it achieved, this river basin organization can be bettered in terms of its organizational structure, manpower strength and experience and balance between top-down and bottom-up decision making process by integrating social learning process. The growing challenges due to the inevitable effects of critical factors of economic growth, population increase and climate change impacts within Langat River Basin for the efficient and effective operation of river basin system. The aim of this paper is to highlight the drawbacks and policy gaps of water resources management in this river drainage area in order to tone up the management initiatives. Here we discuss about the process that led to an integrated approach to the water resources management through the inclusion of local stakeholders and also compare to the European Social Learning model that how it might be set with the perspectives of the Malayan Peninsula.
