Based on National Coastal Erosion Study 1986, Malaysia’s shoreline are classified into three categories of erosion depending to the threat it caused to the existing shore-based facilities of substantial economic value and defined as follows:
Category 1:Shorelines currently in a state of erosion and where shore-based facilities or infrastructure are in immediate danger collapse or damage.
Category 2:Shoreline eroding at a rate whereby public property and agriculture land of value will become threatened within 5 to 10 years unless remedial action is taken;
Category 3:Undeveloped shoreline experiencing erosion but with no or minor consequent economic loss if left unchecked.

1.1 Punca Hakisan
The cause of erosion are both natural and man-induced. A beach in its natural state experiences cycles and deposition but over a long period of time, a beach is considered stable if its mean position remains unchanged. In most cases, the root cause of erosion have been man-made activities which result in direct or residual impact to the nearshore and the beach. Among causes of erosion as listed below:
a)Causes of erosion - natural
b)Causes of erosion - man-made
1.2 Coastal Erosion Mitigation Measures
a) Hard Engineering
b) Soft Engineering
Integrated Shoreline Management Plan (ISMP)
2.0 Integrated Shoreline Management Plan (ISMP)
The ISMP programs carried out by the DID is tailored along the principles of ICZM to address the major issues and problems facing our shoreline.
2.1 Objective of ISMP
2.2 Determination Of Limit Of Shoreline Area
One of the important decisions in carrying out the ISMP is to determine the limits of the shoreline area. The management area should include all the coastal resources of interest and also include all the coastal processes. The limit may vary from place to place, but as a general guide, the following landward and seaward limits have been adopted:-
2.3 Division Of The Shoreline Into Management Unit
Over a length of shoreline, the physical characteristics, coastal features and land use vary tremendously, making it rather difficult to formulate meaningful guidelines or policies. In order to overcome this problem the shoreline is sub-divided into smaller units called management units. A Management Unit can be defined as a length of shoreline with coherent characteristics in terms of both natural coastal processes and land use. An illustration of the management unit is as shown as below.
2.4 Status To Date
To date, JPS Malaysia has completed ISMP for Pahang, Melaka, Negeri Sembilan, Pulau Pinang, Labuan and Miri, Sarawak. Two other ISMP is currently ongoing that is ISMP Sabah and ISMP Johor.
