Water is a key environmental issue. • There concept of sustainable development is in managing • the environment effectively and treating the environment as • a common global good (example water). • This is a basic discussion of a globally key environmental • issue: WATER. • Water Demand: • 60 % increase from 9,543 Mld in 1995 to 15,285 Mld in • 2010 • 113 % increase from to 20,338 in 2020. • Several parts of Malaysia experience severe water • shortages due to drought in 1998. • New source works for addition supplies to meet future • needs. For e.g. water from Pahang Rivers. • Water Pollution Problems

The demand for monitoring data is expected • to grow significantly, • On 1st January 1995, a national corporatised • private body operates the monitoring • activities based on a concession agreement • between DOE and ASMA. • • In-situ measurements of more than 6 parameters • – Turbidity, dissolved oxygen, salinity, temperature, • pH and electrical conductivity. • • Laboratory analyses of as many as 24 other • chemical and Biological parameters. 3.

Modeling been widely utilised in Environmental • Impact Assessment (EIA) for prescribed • activities, but on small scale. • • Under the legislation, all prescribed activities are • required to submit to DOE EIA report for approval • prior to project implementation. • Normally some modeling works are incorporated. • • Now, DOE has programs to model the river water • quality on river basin scale starting with few rivers • – including Langat River, Segget River, Tebrau • River and Rajang River. 5. Water Quality Modeling
River classifications for major rivers have been completed. • Now 24 rivers. • Under the Eight Malaysian Plan (2001-2005) and the Third Outline Perspectives Plan (2001-2010), emphasis given to improve river water quality and integrated river basin management. • Some rivers have been set to attain Class II. 6. Policy Decision from Monitoring Activities
• Program for the pollution prevention improvement of river water quality has been planned and implemented as of 2001. • 26 rivers identified. • In 2001, the program started with 6 rivers namely: Langat River, Skudai River, SeggetRiver, Tebrau River, Melaka River and Miri River. 7. Program Implementations
Rajah 1. Malaysia : Lembangan Sungai yang Terlibat Di bawah Program Pencegahan Pencemaran Sungai dan Peningkatan Kualiti Air, Rancangan Malaysia ke LapanFigure 1. Malaysia : River Basins Selected under the River Pollution Prevention andWater Quality Improvement Program, Eighth Malaysian Plan • The program is intended to improve the • river water quality to regain its clean • status and to restore the natural beauty • and the beneficial uses of the water. • The effort aims to ensure the sustainability • of the water uses in the basin.
Non-ocean water is a very limited resource. • Only 3% of Earth's water is available for human consumption but large portions are either inaccessible or due to pollution, unfit for human use • Non-ocean 3% (ground water, glaciers, inland seas, ice caps, other) • Oceans 97%
Explore the web-linking water pipe where you will get an excellent overview and information related to Earth’s water. • Explore the dripping pipe at USGS. • You should then proceed to explore patterns of water use, again by referring to a “dripping web-pipe”, at: http://ga.water.usgs.gov/edu/wateruse.ht...
Role of Water Management Authority in Malaysia (Department of Irrigation and Drainage, Ministry of Natural Resources and Environment, Malaysia). • Water Resources Management • 3 Aspects of Water Resources Management: • Water in Environment Enhancement • Water in Agriculture and Food Production • Protection from Water as a Destructive Force (DID, 2007)
Environmental Impact and Water Conservation • Environmental Impact Assessment (EIA) • EIA is a formal process used to predict and assess the environmental consequences of a development project. • The purpose is: • to support the goals of environmental protection & sustainable development, • to integrate environmental protection and economic decisions at the earliest stages of planning, • to mitigate adverse impacts resulting from the proposed activity; and, • to provide for involvement of the public, Government and Government agencies in the review of the proposed activities. http://www.tuv-sud.in/EnvImpact&WaterConservation.asp
Environmental Impact and Water Conservation • Water Audit study is a qualitative and quantitative analysis of water consumption to identify means of reuse and recycling of water. • It not only promotes water conservation and delivers cost savings, but also helps companies safeguard public health & property, improve external relations & reduce legal liability. • This has been recognized as necessary and is in the process of assessments. http://www.tuv-sud.in/EnvImpact&WaterConservation.asp
Irrigation and Drainage • Irrigation and drainage development and management however, will continue to be with DID, as it is a critical input for agriculture development. • With the same theme, irrigation and agriculture drainage development too will have to be approached as a business with new and innovative technologies.
Key Performance Indicators (KPIs) • Malaysia has to operate on a performance-based system. • Our modernization efforts will continue and the benchmarking programs will be refined. • We have established key performance indicators (KPIs) for open channel system efficiency to be increased to 60% and our water productivity to be above 0.5 kilogram per metre cube of water. • Efforts are already underway to study the feasibility of converting some of the open channels to pipelines.
Agriculture Drainage • Agriculture drainage is a very important aspect of our agriculture especially when we reveived an average of 3000 millimetres of rain annually. • There are many successes at agricultural land reclamation and drainage projects such as the 240,000 hectare Western Johor Agriculture Drainage Project, Kalaka-Saribas in Sarawak and the coastal plains of Peninsular Malaysia. • But these systems need to be refined if the objectives of the New Agriculture are to be achieved. • Particularly challenging is agriculture in the peat and acid sulphate soils. • In addition, we now have to solve the frequently conflicting drainage needs of agriculture with that for the ever expanding urban growth centres located within the agriculture area.
