Mentor’s Comment: UPSC mains have always focused on Sustainable Development (2016, 2017, 2018 and 2022), and Budget Initiatives (2017 and 2021).
Currently, India holds only about 0.05% of the global market share in shipbuilding, significantly lower than competitors like China (47%), South Korea (30%), and Japan (17%). This disparity highlights that without addressing inefficiencies in container movement and logistics integration, infrastructure growth alone will not lead to meaningful progress.
The editorial discusses the recent positive developments in India’s shipping industry, particularly following the government’s announcements in the Union Budget 2025-26. This content can be used to present challenges in the Maritime Sector.
_
Let’s learn!
Why in the News?
The Union Budget 2025-26 appears to have met most of the shipping industry’s demands; but it has missed an opportunity to address tax disparities.
What specific government initiatives are being introduced to support the shipping industry?
- Maritime Development Fund (MDF): This initiative is the establishment of a MDF with an initial corpus of ₹25,000 crore which aims to provide long-term financing for the shipbuilding and maritime sectors, facilitating investment and growth within the industry.
- Shipbuilding Financial Assistance Policy: The government has announced a revamp of the Shipbuilding Financial Assistance Policy (SBFAP) which aims to address cost disadvantages faced by domestic shipyards by providing direct financial subsidies, thereby encouraging local shipbuilding and enhancing competitiveness.
- Customs Duty Exemptions and Incentives: This Budget extends customs duty exemptions on inputs and components used for manufacturing ships for more than 10 years.
- Additionally, credit notes will be issued for shipbreaking activities, promoting a circular economy within the industry in order to make shipbuilding and recycling more competitive.
- Extension of Tonnage Tax Scheme: The benefits of the existing tonnage tax scheme, which previously applied only to sea-going ships, will now be extended to inland vessels registered under the Indian Vessels Act, 2021.
- This change aims to promote inland water transport and enhance the overall efficiency of the maritime sector.
- Establishment of Shipbuilding Clusters: The Indian shipping industry has been advocating for the extension of the Shipbuilding Financial Assistance Policy (SBFAP) for another 10 years under the Amritkaal Maritime Vision 2047.
- The government plans to facilitate the creation of shipbuilding clusters to increase capacity and capabilities in ship manufacturing.
How can these initiatives impact India’s position in the global shipping market?
- Enhanced Global Competitiveness: By establishing the Maritime Development Fund and revamping financial assistance policies, India aims to boost its shipbuilding capabilities and reduce costs associated with ship construction and repair.
- This could elevate India’s ranking in global shipbuilding from 22nd to potentially within the top 10 by 2030 and top 5 by 2047, thereby increasing its share of global ship tonnage from less than 1% to around 5%.
- Improved Infrastructure and Efficiency: The government’s focus on port modernization through initiatives like the Sagarmala Programme and Maritime India Vision 2030 is set to enhance port infrastructure, logistics efficiency, and multimodal connectivity.
- These improvements will reduce turnaround times for vessels and lower logistics costs, making Indian ports more attractive for international shipping lines and increasing cargo handling capacity significantly.
- Attracting Foreign Investment: With a favorable investment climate that allows 100% Foreign Direct Investment (FDI) in port development, India is positioned to attract significant foreign capital into its shipping sector.
- This influx of investment can lead to technological advancements, better operational practices, and increased capacity, further solidifying India’s role as a key player in global maritime trade.
What challenges does the Indian shipping industry face despite these positive developments?
- High Costs and Financial Constraints: Indian shipyards face significant cost disadvantages compared to global competitors, particularly in terms of higher material and labor costs, as well as expensive financing options.
- This results in a 25-30% cost disadvantage for Indian shipyards compared to those in countries like China and South Korea.
- Additionally, the imposition of a 5% Goods and Services Tax (GST) on ship imports, which is not refunded for international operations, further strains financial resources for shipping companies.
Does the SARFAESI Act impact loan availability?
- Under Section 31(d) of the SARFAESI Act, banks and financial institutions cannot create a security interest in vessels as defined by the Merchant Shipping Act, 1958.
- This limitation means that lenders cannot easily seize and auction ships in case of loan defaults, which reduces their willingness to extend credit to shipowners.
- The ongoing discussions about amending the SARFAESI Act to include provisions for ships indicate a recognition of these challenges.
- By allowing banks to hold security interests in vessels, the government can enhance loan availability and create a more favorable environment for financing within the maritime sector.
|
- Infrastructure Bottlenecks: Major Indian ports are grappling with issues such as congestion, inefficiency, and inadequate infrastructure to support increasing traffic volumes.
- The growth in cargo traffic has outpaced the development of port facilities, leading to delays and higher operational costs.
- For example, backlogs for rail freight have increased significantly, impacting the timely movement of goods.
- Furthermore, labor strikes and outdated technology contribute to lower productivity at ports, making them less attractive to global shipping lines.
- Dependence on Foreign Suppliers: Indian shipyards heavily rely on foreign suppliers for critical components and technology, which increases costs and complicates supply chains.
- This dependency results in longer lead times for procurement and vulnerability to supply chain disruptions.
- The lack of a robust domestic supply chain for high-tech maritime components further exacerbates these challenges, limiting the competitiveness of Indian shipbuilding firms.
Way Forward:
To realize its aspirations under the Amritkaal Maritime Vision 2047, India must prioritize investments in infrastructure, streamline regulatory processes, and foster a skilled workforce.
- The path forward requires a concerted effort from all stakeholders to transform these challenges into opportunities for sustainable development in the maritime sector.
- Establish a National Port Grid Authority to coordinate development across major and minor ports, promoting specialization and eliminating inter-port competition.
- Implementing a hub-and-spoke model with mega ports acting as transshipment hubs can optimize cargo movement and efficiency.
- Deploy Smart Port Infrastructure Management Systems (SPIMS) and introduce blockchain-based Port Community Systems to facilitate paperless and IoT based trade.

From UPSC perspective, the following things are important :
Mains level: Mental Health;
Why in the News?
The Ministry of Labour and Employment’s 2024 report indicates that all States and Union Territories must complete harmonization and pre-publication of draft rules for new Labour Codes by March 31, 2025, allowing for mental health provisions.
How does social inequality impact mental health access and outcomes?
- Disparity in Access to Care: Social inequality leads to significant disparities in access to mental health care services. Individuals from lower socio-economic backgrounds, particularly blue-collar workers, often face barriers such as lack of awareness, stigma, and inadequate healthcare infrastructure, resulting in a treatment gap of 70% to 92% for mental disorders in India.
- Workplace Conditions: Blue-collar workers frequently endure demanding jobs with poor working conditions, job insecurity, and inadequate pay, which can exacerbate mental health issues. These conditions contribute to higher rates of stress and mental disorders among this demographic compared to their white-collar counterparts.
- Limited Legislative Protections: The existing labor laws primarily focus on physical safety and do not adequately address mental health concerns. This legislative gap perpetuates the marginalization of blue-collar workers in accessing mental health resources and support.
What legislative and policy changes are necessary to promote inclusivity in mental health care?
- Rights-Based Framework: Establishing a rights and duty-based legislative framework that mandates employers to ensure both physical and mental well-being is crucial. This framework should include clear definitions of occupational diseases that encompass mental health issues arising from work conditions.
- Inclusion of Mental Health in Labor Codes: The upcoming labor codes should explicitly incorporate provisions for mental health, creating a liability-based framework for employers to prioritize the mental well-being of their employees. This includes recognizing stress-related conditions as occupational hazards eligible for compensation.
- Awareness and Accessibility Initiatives: Legislative measures should mandate employers to promote awareness of available mental health resources, such as helplines and support programs like Tele Manas, ensuring that blue-collar workers are informed and encouraged to seek help without stigma.
What are the steps taken by the government?
- Implementation of National Mental Health Policies: The Indian government has implemented policies such as the National Mental Health Policy (2014), which emphasizes the integration of mental health services into primary healthcare.
- Launch of Mental Health Initiatives and Helplines: Initiatives like Tele Manas, a government-run mental health support service, have been introduced to provide confidential telephonic counselling for individuals.
- Increased Mental Health Awareness through Education and Campaigns: Programs like the “Mental Health Awareness Campaign” and partnerships with organizations like WHO have aimed to educate the public about mental health.
|
How can societal attitudes towards mental health be transformed to reduce stigma? (Way forward)
- Education and Awareness Campaigns: Raising awareness through national and local campaigns can help normalize mental health discussions. For example, the “It’s Okay to Not Be Okay” campaign in India aimed at addressing mental health issues in the workplace.
- Media Representation and Positive Portrayal: The media plays a significant role in shaping public attitudes. Portraying individuals with mental health issues as strong, resilient, and capable of leading successful lives can help shift negative perceptions. For instance, Bollywood movies like “Dear Zindagi”.
- Involvement of Influential Figures: Public figures such as celebrities, politicians, and community leaders can be instrumental in reducing stigma by sharing their personal mental health stories. When Virat Kohli, an Indian cricketer, spoke openly about struggling with mental health issues, it made a powerful impact and encouraged others.

From UPSC perspective, the following things are important :
Mains level: Ethanol production ;
Why in the News?
Union Minister Nitin Gadkari announced that India will reach its goal of blending 20% ethanol with petrol in the next two months, a year earlier than planned. This will require producing about 1,100 crore litres of ethanol in a year.
Does India’s ethanol distillery industry have the capacity to produce large ethanol?
- Current Production Capacity: India’s ethanol distillery capacity has significantly increased to 1,600 crore litres as of 2024-25, up from 423 crore litres in 2019-20. This expansion has been driven by government incentives and a stable market for ethanol.
- Projected Production: To meet the target of 20% blending of ethanol in petrol, approximately 1,100 crore litres of fuel ethanol will be produced annually, with sugarcane expected to contribute around 400 crore litres this ethanol year.
- Diverse Feedstocks: Ethanol production is now utilizing not just sugarcane but also high-grade molasses, broken rice, and maize, indicating a shift towards a more diversified feedstock strategy.
- Government Support: The Indian government has implemented various measures to boost ethanol production, including reducing the Goods & Services Tax on ethanol and encouraging the establishment of grain-based distilleries.
Why have maize imports increased substantially in the past year?
- Rising Demand for Ethanol: The increase in maize imports can be attributed to the government’s restrictions on using sugar and high-quality molasses for ethanol production, leading to a greater reliance on maize as an alternative feedstock for ethanol.
- Import Figures: From April to June 2024, approximately ₹100 crore worth of maize was imported. For the fiscal year 2023-24, maize imports reached about $33 million, with total imports from April to November 2024 valued at $188 million.
- Impact on Domestic Production: As farmers shift towards maize cultivation due to its lucrative potential for ethanol production, maize output is projected to reach around 42 million tonnes for the 2024-25 ethanol year, with an estimated 9 million tonnes available for ethanol production.
- Market Adjustments: The growth in maize cultivation is expected to continue without necessitating further imports due to favourable conditions for Kharif crops this year. Farmers are increasingly diverting maize from traditional uses to meet the demands of the ethanol market.
What are the significance of the ethanol distillery industry?
- Energy Security and Reduced Import Dependence: The ethanol distillery industry plays a crucial role in enhancing India’s energy security by reducing reliance on imported fossil fuels. By blending ethanol with petrol, India aims to substitute a significant portion of its crude oil imports, which account for over 87% of its needs.
- Environmental Benefits: Ethanol production and blending contribute to significant reductions in carbon emissions and urban air pollution. Ethanol’s chemical properties allow for more complete combustion, which lowers harmful emissions such as carbon monoxide and particulate matter.
- Economic Growth and Rural Development: The ethanol industry stimulates economic growth by providing additional income streams for farmers through the cultivation of sugarcane, maize, and other biofuel crops. This has led to increased investments in distilleries and agro-processing industries, creating jobs and revitalizing rural economies.
- The government’s initiatives, such as the PM-JI-VAN Yojana, further incentivize ethanol production, ensuring stable farmer incomes and promoting diversification in agricultural practices.
Way forward:
- Enhancing Domestic Maize Production: Strengthen R&D in high-yield maize varieties, improve irrigation infrastructure, and provide financial incentives to farmers to ensure a stable domestic supply for ethanol production, reducing import dependency.
