In the existing era, international trade is boosted by maritime freight movement. The academicians and Government are concerned about environmental contamination caused by maritime goods that transit global growth and development. Digital technologies like blockchain help the maritime freight business to stay competitive in the digital age. This study aims to illuminate blockchain technology (BCT) adoption aspects to alleviate early industry adoption restrictions.

This study adopts a two-stage approach comprising of structural equation modeling (SEM) with artificial neural networks (ANN) to analyze critical factors influencing the adoption of BCT in the sustainable maritime freight industry.

The SEM findings from this study illustrate that social, organizational, technological and infrastructual and institutional factors affect BCT execution. Furthermore, the ANN technique uses the SEM data to determine that sustainability enabled digital freight training (S3), initial investment cost (O5) and trust over digital technology (G1) are the most essential blockchain deployment factors.

The hybrid approach aims to help decision-makers and policymakers examine their organizational blockchain adoption goals to construct sustainable, efficient and effective maritime freight transportation.

The existing literature reflects that the connection between enablers of Industry 4.0 (I4.0), Supply Chain (SC) sustainability and reliability is understudied. To cover this gap, the purpose of this study is to identify and benchmark the enablers of I4.0 for SC sustainability to build a Reliable Supply Chain (RSC).

This study benchmarks the I4.0 enablers for SC sustainability for building a RSC and analyses them with a multi-method approach. The identified potential enablers are validated empirically. A multi-method approach of Analytical Hierarchy Process (AHP), Decision Making Trial and Evaluation Laboratory (DEMATEL) and Preference Ranking for Organization Method for Enrichment Evaluation (PROMETHEE-II) was used to investigate the influence of the identified benchmarking enablers and develop an interrelationship diagram among the identified enablers.

This study benchmarks the potential enablers of I4.0 to achieve high ecological-economic-social gains in SCs considering the Indian scenario. Digitalization of the supply chain, decentralization, smart factory technologies and data security and handling are the most prominent enablers of I4.0 for SC sustainability to build a RSC.

The findings from the study may benefit managers, practitioners, specialists, researchers and policymakers interested in I4.0 sustainability applications.

Call it the curse, the myth, the legend, the dacoits, the flora and fauna, the River, and the valley remains untouched and pristine and is home to many endemic species and is blessed with stark but beautiful landscape, the surreal world of an era gone by, the ravage of the ravines, which have been preserved, protected, and conserved, albeit for the ‘ancient curses,’ and yes being a home to the ‘dreaded outlaws’ and ‘modern dacoits.’ Whether it was the fear for one’s life considering it was a dacoit area or also known as ‘gun powder area,’ or the curses that none wanted to garner to themselves, Chambal is slowly but steadily ebbing out of the dark shadows that it once was. The river itself passes through Madhya Pradesh, Rajasthan, and Uttar Pradesh, before joining the river Yamuna. Declared a Protected Area (PA) in 1978, the nomenclature of dark tourism will be ubiquitous to the Chambal River valley, considering that the area is dotted by a multitude of forts, and heritage destinations, that have frozen in the sands of time; either on account of the stories that meander, as the river does, with its deep ravines, ravines that invite the adventurer. It is the last bastion for the nation’s endangered wildlife, viz., Gharial, Maggar, Turtles, Otter, and the fresh water Dolphin, which has encouraged the Government to get the local community to be part of the special purpose vehicle promoting tourism. The authors known for their contribution to community-based ecotourism (CBE) have visited the Chambal area and worked with the communities and bureaucracy to ensure conclusions.
