Landslides are a ubiquitous natural hazard in mountainous terrain and often lead to human casualties in urban settlements and along transportation corridors. Given the adverse topographical and climatic setting, both Malaysia and Hong Kong are vulnerable to rain-induced landslides. For example, the 1996 Keningau debris flow in Sabah recorded the highest level of fatality (>300 deaths) for a single landslide in Malaysia. Upon the loss of more than 150 lives in three disastrous landslides in the 1970s, the Hong Kong Government established the Geotechnical Engineering Office (GEO). In striving to achieve its missions of saving lives and facilitating sustainable development, the GEO has made notable advances over the years in the understanding of initiation and propagation of landslides, masterminded the implementation of a systems approach to manage landslide risk holistically, championed the development of novel methodologies for landslide risk assessment, and pioneered new design approaches for landslide prevention and mitigation works. This paper highlights the successful application of innovation and technology in advancing slope engineering practice andmanaging landslide risk. The prospects of the geotechnical profession entering into a new era of making further transformational advances through a wider use of innovation and emerging technology are discussed.

ABSTRACT Dense urban development on a hilly terrain coupled with intense seasonal rainfall and heterogeneous weathering profiles give rise to acute debris-flow problems in Hong Kong. The Geotechnical Engineering Office (GEO) of the Hong Kong SAR Government has launched a holistic research and development (R&D) programme and collaborated with various tertiary institutes and professional bodies to support the development of a comprehensive technical framework for managing landslide risk and designing debris-flow mitigation measures. The scope of the technical development work includes compilation of landslide inventories, field studies of debris flows, development and calibration of tools for landslide run-out modelling, back analysis of notable debris flows, physical and numerical modelling of the interaction between debris flows and mitigation measures, formulation of a technical framework for evaluating debris-flow hazards, and development of pragmatic mitigation strategies and design methodologies for debris-flow countermeasures. The work has advanced the technical understanding of debris-flow hazards and transformed the natural terrain landslide risk management practice in Hong Kong. New analytical tools and improved design methodologies are being applied in routine geotechnical engineering practice.

The scarcity of feeder stock of Bali cattle (Bos javonicus domesticus) in Kupang Regency is currently increasing. One of the contributing factors is the difference in management between the fattening business that produces beef cattle and the breeding business that produces feeders and heifers. The research aims to determine: the interaction between actors to increase the supply of feeder; the behavior of feeder population based on actual stock management, and the necessary policy interventions to increase the supply of feeder. The research was conducted by applying a dynamics systems approach. This modelling used ventana systems software. Data and mental models were collected through observation, focus group discussions, and in-depth interviews with key informants. The results showed that the interaction between actors was limited to the marketing of cattle for both local and domestic markets. The actual feeders supply management shows that cattle population tends to decline due to low calving rate (70%), high calves mortality (35%), and the high slaughtering of productive females (80%). The necessary policy interventions are to implement various efforts to increase the calving rate to be 80%, reduce the mortality rate by applying 2% feed supplementation, and reduce the sales of productive females to be 50%. The actual supply management of Bali feeders needs to be engineered by increasing stakeholder services that coordinate synergistically for learning innovation and technology. It is necessary to establish a breeder cooperative to suppress the sale of productive cows as the cause of its high slaughtering
