“…Due to different types of indicators and significant numerical differences in ecological development, a combination of qualitative and quantitative AHP was chosen for analysis [23][24][25]. By decomposing complex problems into several levels and factors, and performing simple comparisons and calculations between each factor, different scheme weights can be obtained [26,27].…”

On 22 December 2000, the State Council of China officially released the National Outline for Ecological and Environmental Protection. In order to further implement the concept of the Outline, the State Environmental Protection Administration of China proposed to comprehensively promote the creation of ecological demonstration areas. As the most basic independent administrative unit in China, township administrative regions are a key bridge connecting cities and rural areas. The comprehensive ecological planning of townships is an important means to promote rural urbanization and promote rural environmental protection work. It is also a concrete manifestation of the scientific development concept and sustainable development (SD) concept in rural work. The research focused on Yuntai Town, Changshou District, Chongqing as the research object and analyzed the physical geography information and socio-economic situation of Yuntai Town. Then, based on the reference of previous achievements, a comprehensive ecological environment evaluation index system was constructed, and an analytic hierarchy process (AHP) was used to evaluate the evaluation indicators. In order to improve the objectivity of AHP, a fuzzy analysis method was used in the experiment to improve the process. On the basis of studying the actual situation of Yuntai Town and based on the established evaluation index system, this study offers targeted suggestions for the deficiencies in the comprehensive ecological planning of Yuntai Town. The establishment of a comprehensive ecological planning and evaluation index system in Yuntai Town has theoretical and practical significance for the SD of the town.

“…One can further discretize the broad outline within the constraints set by material, technological, economic, legal, environmental and human-related considerations that change with time [5]. Correspondingly, an operational requirements hierarchy is developed in Cheemakurthy and Garme [13] starting with route type on the primary level, followed by vessel requirements at the secondary level and ferry performance requirements at the tertiary level as shown in Fig. 1.…”

Background: Among the challenges for implementation of Waterborne public transportation (WPT) are the difficulties in procuring efficient ferries tailored towards local requirements. Fundamental questions on the ferry’s environmental impact, speed and procurement costs linger in the public transport (PTP) mind. Objective: In this paper, a methodology for adopting a platform architecture for ferries is illustrated by a modular design approach. Methods: For this, WPT operational profiles are categorized by three route types in a structure for operational requirements including sustainability performance. Generic parameters for size and speed of WPT ferries are defined. Using these parameters as a skeletal structure, a modular commuter ferry concept is proposed as a set of basic modules. As a combination of these functionally independent modules, a ferry can be tailored to fit the operational requirements. Results: The paper proposes standard sizes for waterborne commuter craft and shows that ferries are compatible with land-based public transport in terms of energy efficiency and speed. Suitable speed ranges for mono hulls and catamarans are investigated and the idea of modular design for rational procurement is explored and illustrated for the three type routes. Conclusions: The proposed concepts can make WPT more attractive for PTPs as a sustainable option to complement the existing network.

“…Water-borne transportation is attaining significance as a viable solution to combat the escalating pollution and congestion challenges in cities, also seamlessly integrating into the multimodal transport network (Cheemakurthy & Garme, 2022). There is an ongoing discussion regarding the extent to which prominence advancement in ship design, regulation, technology, and risk management systems have contributed to a 70 % drop in shipping accidents and losses over the past decade (Allianz Global, 2021).…”

The domestic ferry sector is uniquely distinctive owing to its challenging navigation conditions and vulnerable accident records that have evoked endless calls for improving maritime safety. The recent adoption of IMO model safety regulations offers viable options for the Member States to standardize incorporation into national law. The operations of domestic ferries range from very large vessels with freight to small craft, which are often the only transport means for a large population of commuters in the developing world. The flexibility of domestic ferries is appealing; on the other hand, their operations are a challenge to handle, raising the need to identify those challenges that are incompatible with smooth operations and business opportunities. The maritime industry, specifically regarding domestic ferry operations, confronts multilayered challenges with direct implications on accident prevention and operational safety that necessitate a thorough analysis for a comprehensive understanding. This study explores five categories, namely, operations, technology and innovations, the human element, policy and regulation, and economics, recognized as pivotal to improving maritime safety. Our content analysis identifies the comprehensive taxonomies, that explain the current challenges and practical opportunities faced by the sector and which are notably lacking, urging efficient tenacity to ensure sustainable domestic ferry operations. The primary objective was to enhance safety standards, promoting sustainable shipping for all stakeholders involved. This study has identified 28 challenges and 90 opportunities, providing a significant pathway for sustainable decision-making that also adds value to the safety of the stakeholders. This study is expected to explore novel and fertile future research areas to promote scholarly discussion in the domestic ferry sector. Highlights Policy deficiency - Recognition of inadequate policy frameworks for domestic ferry operations in developing nations, necessitating immediate alignment with international safety standards Governance strengthening - There is an swift need for strong governance structures to address deficiencies in policy formulation, regulatory enforcement, and operational practices, ensuring effective safety oversight Standardization challenges - The absence of standardized definitions and categorizations hampers the development of uniform safety regulations within the domestic ferry sector Capacity building - Continuous training programs are necessary to foster a safety-conscious culture among the domestic ferry workforce Policy adaptation - Policies must adapt to technological advancements, and collaboration with international bodies is vital for enhancing safety standards within the domestic ferry sector
