Flood disaster management in Malaysia: an evaluation of the effectiveness of government resettlement schemes

In disaster management, relocation/resettlement is more often seen as the worst option as it gives the impression that nothing else can be done about the hazard and people have to be moved. Relocation is unpopular, as plans to relocate entire communities are costly, mainly because of the need to acquire alternative locations and the provision of housing for those resettled. More significantly, at least on the part of those being relocated, it provokes social disruption and upheaval when people are bundled into an alien environment. Notwithstanding the influence of structural/societal forces, people are also reluctant to be relocated far from relatives, friends and their place of work (or schools in the case of children). Examines the effectiveness of government‐run permanent relocation schemes as a response to flood hazards in Malaysia.

An assessment of agricultural sustainability indicators in Bangladesh: review and synthesis

The term ‘indicator’ is often vague and heterogeneous, and its dynamic characteristics make it highly variable over time and space. Based on reviews and synthesis, this study visualizes phenomena and highlights the trend of indicator selection criteria, development methods, validation evaluation strategies for improvement. In contextualization of the intensification of agriculture and climate change, we proposed a set of indicators for assessing agricultural sustainability in Bangladesh based on theoretically proposed and practically applied indicators by researchers. Also, this article raises several issues of indicator system development and presents a summary after due consideration. Finally, we underline multi-stakeholders’ participation in agricultural sustainability assessment.

Increasing flood risk in Malaysia: causes and solutions

Discusses flood risk in Malaysia, which has increased alarmingly in recent decades largely due to changing physical characteristics of the hydrological system caused by human activities: continued development of already densely populated flood plains, encroachment on flood‐prone areas, destruction of forests and hill slopes development. Flood losses are high but disastrous flood events which occurred in the past as a consequence of rapid development and environmental degradation are forgotten quickly, people choosing to see only the positive benefits of a booming economy while turning a blind eye to their negative effects. Suggests that, within a climate of sustained economic boom, policy makers as well as Malaysians from all walks of life are understandably less concerned about floods than they are about the financial gains that can be reaped from a booming economy. States that official solutions for flood control are largely engineering based and are ineffective to combat extensive monsoon floods.

Responding to landslide hazards in rapidly developing Malaysia: a case of economics versus environmental protection

Malaysia is an ex‐colonial, newly‐industrialising country, with a sustained high economic growth rate averaging eight per cent GDP per annum over the past ten years. Within such a rapidly booming economy, the pace of social, economic and political change is fast, as is the pace of technological change. Other things being equal, these are the changes in which environmental hazards can be magnified. As a result of rapid economic development, physical systems are disturbed and changed. For example, the modification of the hydrological cycle due to deforestation, urbanisation, development of hill slopes and other human land use have given rise to increased risks of landslides. In recent years, the collapse of a block of luxury condominiums in Kuala Lumpur, the Genting Highland and Pos Dipang landslide tragedies as well as other landslide disasters have caused substantial loss of life and damage to property and infrastructure. Combined with intensive development of hill slopes and hill land for housing, recreation, tourism, agriculture, highway and dam construction, and other human induced land use changes, the exposure and vulnerability of human populations to landslide hazards have also increased. Other reasons, largely structural, such as persistent poverty, low residential and occupational mobility, and landlessness, manifested in illegal squatting and farming on hill slopes and foothills have also contributed to increased vulnerability of large communities to landslide hazards in many parts of the country. As Malaysia pushes ahead to meet its target of becoming a fully industrialised country by the year 2020, further environmental degradation is expected to occur. Notwithstanding other aspects of environmental degradation, the occurrence of landslide hazards is expected to become a common feature of Malaysian life.

Impacts of Disasters and Disaster Risk Management in Malaysia: The Case of Floods

Malaysia lies in a geographically stable region, relatively free from natural disasters, but is affected by flooding, landslides, haze and other man-made disasters. Disaster management in Malaysia is traditionally based almost entirely on a government-centric top-down approach. Because Malaysia’s main risk comes from flooding, national disaster mitigation institutions largely target monsoon flooding. However, this mechanism is less than effective and should be re-modeled into something more pro-active. The Drainage and Irrigation Department (DID) is responsible for flood management. However, as an engineering-based organization, DID’s approach is largely focused on structural measures in controlling floods and lacks a holistic approach towards flood management. There is also a need for greater stakeholder participation, especially from NGOs at all levels in the disaster cycle. Malaysia should build capacity for NGOs, local communities and disaster victims. Disaster management mechanisms should also adopt more non-structural measures, bring in state-of-the-art technology and cooperate internationally with other countries for addressing transboundary disasters.

Managing Urban Rivers and Water Quality in Malaysia for Sustainable Water Resources

Rivers are rich ecosystems and sources of life, providing many functions for the survival of natural and human systems. In Malaysia, due to poor management and public apathy, they are severely degraded. Rapid development and urbanization have also overstressed and polluted them, and governance practices are mostly focused on managing water shortages, floods, and pollution. Limitations include low priority in the political agenda, inadequate economic, managerial, and human resources, poor enforcement of laws and regulations, poor public involvement, and inadequate use of non-structural measures. Recent government, private sector, and NGO partnerships, however, have shown great potential for improved management of rivers.

Environmental hazards associated with hill land development in Penang Island, Malaysia: some recommendations on effective management

Increasingly, land is a scarce resource which is much sought after in Penang Island, Malaysia. This is because Penang is largely made up of steep topography and much of the lowland areas are already developed. Penang is one of the many rapidly industrialising states in Malaysia with a largely urban populace. In recent decades, efforts at industrialisation and the development of other economic sectors have been intensified, leading to greater urbanisation and greater pressures on land. Although land reclamation has eased the pressures somewhat, it is not enough to satisfy the high demand for land on the island. As such, developers have turned to the remaining hill land on the island. Many hills and their environs are already being developed and many hill projects are in the pipe line. This has led to many environmental problems such as deforestation, decimation of water catchments, destruction of endangered fauna and flora, soil erosion, landslides, water pollution, sedimentation and downstream flooding.

Institutional arrangements for flood hazard management in Malaysia: an evaluation using the criteria approach

Institutional aspects of flood hazards significantly affect their outcomes in Malaysia. Institutional arrangements to deal with floods include: legislative activity, organisational structures, attitudes and sub-culture, and policies and instruments. When assessed in terms of four specific criteria, institutional aspects of flood hazards are found to be largely inadequate. Disaster reduction programmes are over-dependent on a reactive approach based largely on technology and not even aimed at floods specifically. Structural flood reduction measures are the predominant management tool and, although the importance of non-structural measures is recognised, thus far they have been under-employed. Current laws and regulations with regard to flood management are also insufficient and both the financial and human resources of flood hazard organisations are generally found to be wanting. Finally, economic efficiency, equity and public accountability issues are not adequately addressed by institutional arrangements for flood hazards.

Management of flood disasters in the Jianghan Plain, China

This study examines the causes of flood disasters in Jianghan Plain, China and provides practical solutions to mitigate them. Results from this study indicate that both historical archives and more recent recorded data point to an increasing frequency in flood disasters since 1961. Furthermore, damage and losses from flood disasters have also increased significantly in the region. By analyzing the physical geographic factors and human activities, this study found that the main causative factors contributing to increasing flood disasters are landform/topography, climate elements, reduced drainage capacity of rivers in contrast to increased flood discharge, and human activities. Finally, the study examines various practical solutions to mitigate flood disasters in the Jianghan Plain.

Farming and Other Stakeholders in a Tropical Highland: Towards Less Environmentaly Damaging and More Sustainable Practices

Expansion of smallholder agriculture in many tropical highlands often results in serious environmental damage. The challenge is to reduce such damage and to achieve improved and more sustainable livelihoods. The Cameron Highlands and nearby uplands of Malaysia offer an opportunity to study how farmers adapt. Most have intensified production since the 1970s, some have expanded their holdings, and some have reduced their environmental impacts and have adopted more sustainable practices. Drawing on information collected from the Cameron Highlands between 2002 and 2008, this paper seeks to enhance understanding of those changes.
