A multidisciplinary study of the Bera Lake is presented here, focusing on natural resources throughout the lake’s catchment area and assessing environmental impact. This applied limnology study examines issues relating to land development including soil erosion and nutrient loss in the catchment area, severe pollution of water, sediment resources in open waters and wetlands, and reduction of aquatic and bird populations. The chapters provide a comprehensive view of problems, risks and possible mitigation measures associated with this great natural habitat in Malaysia. The book highlights the technology and methods used to estimate both soil erosion rate and nutrient loss from the lake catchment, including an explanation of the measurement of sedimentation rate in Bera Lake, using 137Cs and 210Pb radioisotopes. The author examines the current and historic situation of contamination in sediments, presents an ecological risk assessment and finally describes a master management plan, proposing practices to mitigate the environmental impacts of existing agricultural projects and practices to control future projects. Readers will learn of a decrease in the watershed supply of water to the Bera Lake, of shoaling, degradation of water and sediment quality and the extinction of several kinds of flora and fauna. This volume also offers an approach to sustainable land use, with regard to natural resources conservation.
