Quantification of changes in seabed topography with special reference to Hansthal Creek, Gulf of Kachchh, India.
(Journal of costal research, 1993-01) Pattanshetti, S.S.; Chauhan, Onkar.; Sivakholundu, K. M.
Variations in the bathymetry in macrotidal Hansthal Creek between 1984 and 1950 along 14 closely spaced lines, are used to quantify the volumetric changes in seabed topography in terms of erosion/accretion. Two surfaces from the bathymetric data of 1984 and 1950 have been modelled. The profile wise comparison along the transects indicates a dynamic deformation due to distinct alteration in the shoreline and a shift in the channel course. The shoreline has retreated 650 and 450 m on the northern and southern banks respectively. The studies suggest scouring of horizontally deposited fine sediments (clays deposited in an antecedent depositional phase) in the Hansthal Creek due to existing dynamic equilibrium among (a) influence of physiography in amplifying the tidal range, (b) increased efflux due to contribution through inter-creek water movements, and (c) high magnitude currents. Magnitude of erosion in the creeks, particularly on the flanks, is much more than in the axial channel. The degree of the erosion reduces from the Hansthal Creek mouth to inland (area in the close vicinity of Little Gulf of Kachchh). During the last 34 years about 71.5 x 10 super(6) m super(3) from this creek during the course of the present study. Offshoreward movement of scoured sediments and their redeposition in the outer gulf as a fill in the paleo-channel is observed.
Significance of income generation activities under micro-finance: A study of micro-finance groups in wayanad district, kerala
(Institute for Social and Economic Change, 2005) Mathew, Emil.
The present paper discusses the necessity of promoting income-generating activities (IGAs) under micro-finance programmes. Under micro-finance programmes, the principle of joint liability ensures access to credit. In the absence of remunerative IGAs, peer pressure forces the members to borrow loans from various sources at the time of repayment and results in indebtedness. The present paper examines the factors influencing the members to undertake IGAs and puts forth some policies to promote productive activities.
Does repayment indicate the success of micro-finance programme
(Institute for Social and Economic Change, 2006) Mathew, Emil.
This paper examines the patterns of loan utilisation and repayment among microfinance group members of Wayanad district of Kerala. It argues that 100 per cent repayment by members need not always indicate the success of group lending. As majority of the members have not undertaken income generating activities, the fear of social sanction and repeated interactions put pressure on them to depend on micro-finance loans at the time of repayment. The absence of alternative credit sources increases the financial dependence of the members over a period of their stay in micro-finance programme.
Review article on the mental health of seafarers
(0000) Chandra, Mihir.
‘Sea the future’ is coined correctly by the name blue economy. But is the future beckons wellbeing of the ‘key worker’? While Covid 19 pandemic halted most of the economic juggernauts in lockdown; it could not put a spanner into the propellers of ships which kept trading for 90% of the global trade 24x7 around the COVID’s variants year, seafarers mental and physical health went through tough times. The articles reviewed had never seen through this unknown tunnel of this decade. Wisdom of hindsight is common but resilience to bounce back may be grasped out of foresight with learnings of gap analysis. Awareness of factors influencing health, as a building block for seafarers’ training from pre-sea level is to be envisioned in the mode of compulsory courseware. Physical fitness and mental toughness modules must be enshrined in courseware with pedagogy and soft skill development through case studies. Research work should pave the way for innovative tools to monitor seafarer health 24X7. The well-being of seafarers may then be addressed potentially.
Enhancing cyber security awareness in maritime industry
(0000) Chandra, Mihir.
Cyber security is the combination of stakeholders, policies, processes and technologies to protect cyber assets of any industry. It is optimized to levels that help shipping personnel define, balance resources required with usability/manageability and the amount of risk offset. The aim of this paper is to develop understanding and awareness of key aspects of cyber security – identify threats, identify vulnerabilities, assess risk exposure, develop protection & detection measures & establish contingency plans. Furthermore, establish guidelines for operators on how to assess their ship’s operations & put in place necessary procedures and actions to maintain the security of cyber systems for marine industry. The integration of technology in shipping operations is being enabled by the integration of Information Technology and the Operation Technology on board ships. This has enhanced the threats of unauthorised access or malicious interventions to ship’s systems and networks. The measures to guard against cyber threats should include, (i) quantification and type of risks to security, environment and commerce if no cyber security measures are in place, (ii) due protection to IT and OT infrastructure and its networked equipment, (iii) management of access (iv) protecting data related with its sensitivity. With emerging technologies, there is a direct applicability of trends like Artificial Intelligence to enhance security and fraud prevention. Extending the use of Security Analytics for understanding and detecting risk level of vulnerabilities, improving the performance of own security policy by removal of unnecessary data, feature extraction and selection, data cut off, parallel processing, machine learning and deep learning algorithms – are some examples for the use of advanced technologies for improving Cybersecurity.
