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
withthis 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."
