Slope failures are common in many parts of the world which occur due to manifold reasons and they result in huge losses to the respective locals. This study evaluates the initiatives that can enhance the safety of slope by considering the remedial measures to deal with the factors causing slope instability and discusses the application of risk management strategies to address the problems that can cause the slope to fail. The methods for the remediation of slope include modification in slope geometry, drainage, use of retaining structures and internal slope reinforcement. This study also discusses the risk management process which is a hierarchical procedure that includes assessment and control of risk through different techniques in order to manage the uncertainties associated with the slope. It has been observed that the implementation of risk management strategy aids in the proper identification of risk and its severity which dictates the selection of appropriate remedial measure for the rectification of slope. For reducing the number of landslides, this study suggests the use of risk based strategies to curtail the chances of slope failure.

Physical risk assessments allow us to understand work-related critical issues, thus representing a useful tool in risk management strategies. In particular, our study focuses on the identification of already known and emerging physical risks related to necropsy and morgue activities, as well as crime scene investigations. The aim of our study is, therefore, to identify objective elements in order to quantify exposure to such risk factors among healthcare professionals and working personnel. For the research of potentially at-risk activities, data from the Morgue of Policlinico Umberto I Hospital in Rome were used. The scientific literature has been reviewed in order to assess the risks associated with morgue activity. Measurements were performed on previously scheduled days, in collaboration with the activities of different research units. The identified areas of risk were: microclimate; exposure to noise and vibrations; postural and biomechanical aspects of necropsy activities. The obtained results make it possible to detect interindividual variability in exposure to many of the aforementioned risk factors. In particular, the assessment of microclimate did not show significant results. On the contrary, exposure to vibrations and biomechanical aspects of load handling have shown potential risk profiles. For this reason, both profiles have been identified as possible action targets for risk management strategies.

<p>Nowadays it is essential to develop new methodologies to quantify landslide risk, which contribute to the landslide risk management at the municipal level. In this work, a Landslide Risk Index (LRI) is computed for the 278 Portuguese municipalities, which are ranked and characterized according the landslide risk drivers. Landslide risk index was assessed as the product of hazard, exposure and physical vulnerability of buildings scores.</p><p>The landslide hazard includes the landslide susceptibility evaluated at the national scale using the Information Value method and further validated with prediction-rate curves (Zêzere et al., 2018). Additionally, a weather and climate events index (WCE) was computed using a multicriteria analysis that included the annual frequency of circulation weather types associated to damaging landslides and an extreme precipitation susceptibility index (Santos et al., 2020). Exposure  was evaluated for each municipality using the population density (inhabitants/km<sup>2</sup>) and the road density (km/km<sup>2</sup>). The physical vulnerability of the buildings was computed using four statistical variables obtained from the official Census: (i) construction technique and construction materials, (ii) reinforced structure, (iii) number of floors and (iv) conservation status. Variable classes were empirically weighted.</p><p>Exposure is the main driving force of LRI in the metropolitan areas of Lisbon and Porto, whereas the hazard is more relevant in the NW municipalities and the physical vulnerability is the major driving force in the south of the country.</p><p>For each municipality a landslide risk profile was built, based on the combination of the three driving forces, which can be compared and ranked. Therefore, the landslide risk management strategies at the municipal level must be adjusted to the corresponding dominant drivers in order to reduce landslide impacts.</p><p>Municipalities with high values of hazard are sensitive to changes on the other risk components, which should draw additional efforts concerning land use management and emergency planning. On the exposure, planning instruments should consider the negative effects on LRI from measures that promote the expansion of people and economic activities towards hazardous zones. On the physical vulnerability, public policies should be aware of the increasing physical vulnerability of buildings in time due to age and lack of maintenance and to public works involving embankments and earthworks.</p><p>This work contributes to context-oriented strategies of landslide risk management that still lacks in most of the national and regional levels of risk governance processes.</p><p> </p><p>Acknowledgements:</p><p>This work was financed by national funds through FCT—Portuguese Foundation for Science and Technology, I.P., under the framework of the project BeSafeSlide—Landslide Early Warning soft technology prototype to improve community resilience and adaptation to environmental change (PTDC/GES-AMB/30052/2017) and by the Research Unit UIDB/00295/2020.

Risk management is an important effort that must be made by Islamic Banking to minimize risk. This research is a qualitative research and the methods used are interviews, documentation, and observation. The research objective was to determine the types of risks in murabahah financing and the strategy of PT. BPRS Artha Madani in overcoming these risks and to find out the analysis of the implementation of risk management strategies carried out by PT. BPRS Artha Madani Head Office Bekasi.Based on the results of the study it is known that the risk management strategy analysis of PT. BPRS Artha Madani using Bank Indonesia Regulation No. 13/23/PBI/2011 and 5 C principles consist of Character, Capacity, Capital, Collateral and Condition of Economy. However, despite implementing the risk management strategy, banks continue to experience risks, namely in the form of: credit risk (in Islamic banks called as financing risk), operational risk and legal risk due to bank internal factors in analyzing and external factors from customers.PT. BPRS Artha Madani in resolving troubled financing with intensive billing, reprimand to customers if they do not fulfill their obligations, make a restructuring by rescheduling, reconditioning and restructuring if the financing can still be normalized. However, if there is no hope and the Customer is not able to, then the solution is guaranteed that can be auctioned through litigation or non-litigation channels.

The objectives of this research were to understand farmers’ perception to risk and risk management strategy on shallot farming. The research was conducted in Bantul and Nganjuk Regency. The number of samples taken were 57 farmers in Bantul and 90 farmers in Nganjuk. Analysis used was frequency table that disaggregate based on agroecosystem and cropping pattern. The result showed that according to farmers’ perception, production and price risk were high. Farmer's decision to follow dominant cropping pattern and production system reflected on the ex ante risk management strategies done by the farmers as their own respection. In the interactive risk management strategies, farmers tended to use chemical fertilizers over chemical pesticides. In ex post risk management strategy, in the failure of shallot farming, they kept cultivating shallot that their capital got on cash and input for shallot farming.

Abstract Background: Laboratory staff is at higher risk of infection owing to the handling and testing of coronavirus disease 2019 (COVID-19) patient samples. Reviewing the existing risk assessment and improving risk management are essential for preventing laboratory acquired infections (LAIs) related to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) testing during the COVID-19 epidemic. We present herein the steps taken to prevent LAIs related to SARS-CoV-2 testing in a tertiary care hospital in Vietnam. Methods: A SARS-CoV-2-focused risk assessment exercise was conducted for laboratory processes and workflow. Risk management strategies, including engineering, administrative and operations control procedures, were established. Standard operating procedure (SOP), staff training, COVID-19 symptom reporting, enhanced cleaning and decontamination, and inventory monitoring protocols were implemented. Sample reception and results reported from February 1, 2020 to September 17, 2020 were documented. Results: Based on risk assessment, a risk management strategy for SARS-CoV-2 testing was developed. This strategy includes the use of dedicated facility, instrument, and cold chain units for testing; SOPs; training (testing, decontamination and cleaning staff); the introduction of biosafety level (BSL)2+ laboratory practices; enhanced cleaning protocols for testing; and the assigning of additional staff for testing and safety system implementation. In total, 38,377 (daily mean and range: 166; 3 – 2,377) samples were received, including 301 (0.8%) samples that were rejected. The turnaround time (median ± standard deviation (SD)) was 3.54 ± 2.97 days. Altogether, 32 staff members were involved with SARS-CoV-2 testing and biosafety management, and there were no reports of COVID-19 symptoms among them. Conclusion: For epidemics and outbreak diagnostics, risk assessment and risk management strategies are important for the prevention of LAIs. Clear instruction on revised risk management protocols, necessary training, and leadership in risk management strategy implementation are essential.

The economies of countries face various risks depending on the environmental conditions. While some of these risks do not pose very serious negative effects on developed economies, they may be destructive on non-developed, underdeveloped or emerging economies. Risk management is accepted as a process for all economies. The risk management process starts with the determination of the risks, and goes on with the assessments of the risks, the determination of various strategies that may respond to the risks; and the application of the most suitable one from among these strategies. In risk management, in order to respond to the risk, emerging economies may select one of the methods like tolerating the risk (accepting it), managing it, transferring, eliminating or making use of its opportunities. In this chapter, the risk management strategies have been explained, examples are given from Turkey, which is has many characteristics of an emerging economic structure.
