Abstract
In recent years Malaysian government has started to pay more attention to the landslide issues, as public outcries grew louder. Some local authorities that are at the front line of public anger whenever major landslides occurred have yet to provide better services while others utilized guidelines and relevant acts to act against errant developers and land owners. As a consequence of this, Public Works Department (PWD) and its Slope Engineering Branch (CKC) will require training, not only in the procedures themselves, but also in regards to the basis of landslide mechanisms, landslide risk assessment and dealing with geotechnical reports at best professional manner. In addition to the success of implementing for the National Slope Master Plan NSMP 2009-2023 would depend on every stakeholder and relevant authorities that includes the public residents and most of all the political parties of the Malaysian government and it is therefore local government and other regulators must establish strong internal procedures for dealing with land use and development proposals on land situated within a landslide susceptibility. Hence, the significance to further examine and assess the value of Malaysian NSMP as being comprehensive national disaster management strategy and a constitution of landside mitigation measures
Highlights
In tropical zones landslides and floods are two major natural disasters that have impacted the countries in terms of injuries, deaths, property damage, disruption and destruction of services, public inconvenience and economic as well as financial losses (Alnaimat et al, 2017)
The results revealed that Malaysian Public Works Department (PWD) has remarkable contribution towards public awareness, education strategy, hazard mapping, assessment strategy, beside early warning system and real–time monitoring, all of these strategies were well contributed via PWD according to the findings and experts view 50% agreed, results implies appositive trend of respondents toward the PWD strategies which contributes in landslides mitigation system that would lead to multi geo-hazard decision support system and engineering mitigation, monitoring, planning and management in term of landslide monitoring procedures and mitigation measures
The results indicated the majority of respondents revealed high agreement with the percentage of 87.50% that (NSMP 2009-2023 strategies and plans going to be carried out and being implemented for long term by PWD or at its authority departments such as CKC and relevant stakeholders)
Summary
In tropical zones landslides and floods are two major natural disasters that have impacted the countries in terms of injuries, deaths, property damage, disruption and destruction of services, public inconvenience and economic as well as financial losses (Alnaimat et al, 2017). In Malaysia the causes of landslides are usually related to instabilities in slopes (Li et al, 2011). It is usually possible to identify one or more landslide causes and one landslide trigger; the difference between these two concepts is subtle but important (Jasmi, 1996). The trigger is the single event that initiated the landslide. Causes combine to make a slope vulnerable to failure, and the trigger initiates the movement. Landslip risk analysis and management has become an important tool in addressing uncertainty inherent in landslide hazards. Multi-criteria decision making approach play significant role in determining relative importance of landslide causative factors in slope instability process (PARDESHI et al, 2013).
