In view of this matter, ASEAN needs to find solutions to adapt to climate change in building a resilient ASEAN; Climate change dilemma driven by urbanisation;by Rebecca Shamasundari ; 26 August 2017


Rice paddies production in Malaysia, as in other parts of the world, is extremely vulnerable to weather changes and extreme conditions such as drought and flooding. Such situations forced Malaysia to maintain a protectionist regime with respect to its rice industry to better ensure food security for the country. In this study, a crop simulation model (DSSAT) and system dynamics approach were used to assess the impact of climate change on future rice production, self-sufficiency level of rice, and farmers’ gross income in Malaysia. Results from the DSSAT model show that during the main and off growing seasons, increase in temperature and changes rainfall pattern can be expected to reduce the rice yield by 12 and 31.3%, respectively, until the year 2030. Based on the system dynamics’ results, the reduction in rice yield was expected to reduce farmers’ gross income and the rice self-sufficiency level of the country. The study suggested two different policy scenarios to overcome these adverse effects. The overall policy implication is that the Malaysian rice industry cannot be sustained if government takes no action to change its current policies.

Water Pollution - Malaysia

-
Image
Water pollution is a serious problem in Malaysia. It reduces total water availability considerably. Cost of treating polluted waters increases and some polluted waters are not treatable for human consumption. Urbanization within our river catchments gives rise to an increase in population and urban life activities.  Land development increases run-off  within  a  catchment,  which  in  turn  affects  the  water  quality  of  receiving  waters. Rainfall in urbanized areas washes down contaminants accumulated on land surfaces into storm water facilities.  The main point sources identified are household sullage, sewage treatment plant and industrial area. Besides these, there are other point sources polluting the river basin such as market, restaurant, workshop, resi-dential area, solid waste disposal sites, soil and sand sourcing, new development area, aquaculture, com-mercial lots, petrol station, livestock and others. The Department of Environment (DOE) maintains records of

Malaysia’s Water Supply Restructuring: A Ten-Year Scorecard

-
By Olivia Jensen: Olivia Jensen is a senior research fellow at the Institute of Water Policy, Lee Kuan Yew School of Public Policy, National University of Singapore.   15 March 2017 In the early 2000s, water supply was a looming problem for Malaysia. The country’s rapid development in the preceding two decades had driven an increase in the demand for water, especially in the main economic centres of Kuala Lumpur and Selangor, and Johor in the south. Water supply and sanitation infrastructure, however, had failed to keep pace and restrictions on water supplies in the capital region were imminent. At the time, the water sector was an organisational, institutional and policy patchwork and financially unsustainable. Tariffs, efficiency and quality of service differed hugely across the country. The states had built up debts to the federal government which they were unable to service. Some states had also signed bulk water supply and concession contracts with private companies
