What’s holding India back in its renewable energy transition?


What’s holding India back in its renewable energy transition?

February 12, 2025

Saloni Sachdeva Michael

 

Key Findings

The deteriorating financial health of distribution companies (DISCOMs) also affects renewable energy deployment in India. Many DISCOMs face financial distress due to mounting losses, inadequate tariffs and inefficient bill collection. These challenges prevent them from signing power purchase agreements, stalling renewable energy projects.

The ISTS waiver exempts renewable energy projects commissioned up to 30 June 2025 from transmission charges, making them cost-effective. Though the Ministry of Power has extended this waiver to green hydrogen and green ammonia projects, such support is also required for hybrid and storage projects to address intermittency challenges and ensure grid stability.

Another concern is India’s 100% reliance on imports for critical minerals essential for renewable energy technologies, such as lithium, cobalt and nickel. Its dependence on foreign sources for these minerals, particularly from China, exposes it to supply disruptions, price volatility and geopolitical risks. 

India has made impressive strides in its renewable energy journey, with its installed capacity reaching new milestones. As of December 2024, the country’s renewable energy capacity surged to 209.44 gigawatts (GW), accounting for 45.3% of its total installed capacity. This growth marks a significant year-on-year increase of 28.65GW (16%), up from 180.79GW in December 2023. 

India has reaffirmed its commitment to achieving 500GW of non-fossil fuel energy capacity by 2030 and net-zero emissions by 2070 – both these goals demand innovation and collaboration across the energy, industry and transport sectors. However, several challenges, including land acquisition issues, regulatory hurdles and financial constraints, continue to impede the large-scale deployment of renewable energy.  

Financial Distress and Legal Uncertainty

The deteriorating financial health of distribution companies (DISCOMs) also affects renewable energy deployment in India. Many DISCOMs face financial distress due to mounting losses, inadequate tariffs and inefficient bill collection. These challenges prevent them from signing power purchase agreements (PPAs), stalling renewable energy projects. The backlog of unassigned PPAs delays project commissioning and creates uncertainty for renewable energy developers, impacting revenue cashflow and financing.

Furthermore, allegations of unfair practices against prominent energy companies from time to time raise concerns about the transparency and fairness of the procurement process. These issues erode investor confidence and discourage stakeholders from investing in renewable energy projects. For DISCOMs, such challenges intensify their financial struggles. Furthermore, delayed payments to developers and uncertainty over PPAs, including renegotiations or cancellations, deepen the strain.

To navigate these hurdles, corporate and industrial (C&I) consumers, who account for a large share of energy demand, increasingly turn to direct procurement options like Green Energy Open Access (GEOA). The GEOA Rules were brought in to promote clean electricity generation, purchase and consumption, and align with India’s Nationally Determined Contributions to achieve net-zero emissions by 2070. A total of 22 Indian companies have set net-zero targets. By promising lower costs and reliable energy supply, GEOA has emerged as a viable alternative to traditional procurement. The GEOA market has attracted new developers like Kalpa Power, JSW Energy and Ampyr Energy, in addition to established companies like ReNew Power and Avaada Energy. The regulatory support provided by GEOA has spurred rapid growth in the C&I open access market, achieving a compound annual growth rate of 46% between the fiscal year (FY) 2022 and FY2024, with cumulative capacity reaching 18.7GW by the end of FY2024. L

Systemic measures to stabilise DISCOMs’ finances, ensure fair practices in energy procurement and enhance transparency are critical. Such interventions can restore confidence, enable developers to proceed with projects and encourage collaboration among stakeholders.

Inter-State Transmission System (ISTS) Waiver to support Hybrid and

Storage Projects

A key enabler of India’s renewable energy growth and competitiveness has been the ISTS waiver, which exempts transmission charges for renewable energy projects commissioned up to 30 June 2025, making them cost-effective. As of 31 December 2024, India had successfully installed 97.86GW of solar and 48.16GW of wind power with an impressive 232.88GW and 74.96GW in the pipeline respectively. This waiver has been particularly crucial for solar and wind energy projects. 

While vanilla renewable energy technologies (just solar or wind) continue to become more competitive and may eventually operate without subsidies, the sector is now shifting to hybrid and capital-intensive projects such as Firm Dispatchable Renewable Energy (FDRE), Round-The-Clock (RTC) power tenders, battery energy storage systems (BESS), pumped storage plants (PSPs) and green hydrogen. These projects, due to their high capital expenditure and infrastructure needs, rely on the ISTS waiver to remain financially viable. Though the Ministry of Power has extended this waiver to green hydrogen and green ammonia projects, exempting them from transmission charges for 25 years, such support is also required for hybrid and storage projects to address intermittency challenges and ensure grid stability.

The lack of sufficient substation infrastructure threatens the viability of projects, particularly hybrid and energy storage projects, which rely on the waiver for financial sustainability. With developers unable to meet infrastructure requirements, these projects risk becoming economically unfeasible. Industry voices are calling for an extension of the waiver to address these concerns. 

Unstable Regulatory Environment Threatens India's Energy Transition

The Central Electricity Regulatory Commission recently rejected a petition to approve the tariff for Solar Energy Corporation of India’s (SECI)'s first standalone BESS project of 500MW/1,000MWh. This decision underscores a critical issue in India’s renewable energy sector – projects are being awarded but often fail to secure buyers, risking cancellation under standard tender rules. This hampers progress towards achieving the 236.22GWh of BESS capacity needed to integrate the planned renewable energy under the Central Electricity Authority’s National Electricity Plan 2023. As of March 2024, India had only 0.2GWh BESS installed capacity.

Another example is the Karnataka High Court’s decision to strike down the Green Energy Open Access Rules, 2022, which disrupts a critical avenue for renewable energy procurement, leaving consumers and developers in limbo. This compounds challenges for project developers and consumers who rely on affordable and direct procurement models.

To overcome these challenges, India must address regulatory hurdles by setting clear tariffs, ensuring buyer identification pre-tender, and enforcing penalties for defaults. Accountability and collaboration among stakeholders are critical for advancing India’s renewable energy goals.

India’s Dependence on Imported Minerals is Concerning

Another concern is India’s 100% reliance on imports for critical minerals essential for renewable energy technologies, such as lithium, cobalt and nickel. Minerals at risk include graphite (natural and synthetic), lithium oxide, nickel oxide, copper cathodes, nickel sulphate, cobalt oxide, and copper ores and concentrates. While India aims to achieve 50% of its electric power capacity from non-fossil fuels by 2030, its dependence on foreign sources for these minerals, particularly from China, exposes it to supply disruptions, price volatility and geopolitical risks. India imports significant amounts of copper cathodes, nickel sulphates, lithium oxide and graphite from China, Russia and Japan, all of which are exposed to trade risks.

The concentration of global mineral refining and processing in a few countries, especially China, is concerning. China accounts for 70% and 85% of the world’s rare earth mining and processing capacities, respectively. Further, global refining of 68% of nickel, 40% of copper, 59% of lithium and 73% of cobalt takes place in China. 

India must accelerate efforts to diversify its mineral supply chain by forging stronger partnerships with mineral-rich nations like Australia, the US and Indonesia. Additionally, India must focus on developing its refining and processing capacity to reduce its dependence on foreign imports and strengthen its critical minerals supply chain.


Conclusion

India’s renewable energy journey has been nothing short of remarkable, with significant progress in expanding its clean energy capacity. While challenges remain, India has shown resilience and innovation in addressing its energy transition obstacles. Financial struggles of DISCOMs, an unstable regulatory environment and reliance on imports for critical minerals threaten to derail India’s clean energy transition. However, by implementing systemic reforms to stabilise DISCOM finances, extending support to hybrid and storage projects, and diversifying the supply of critical minerals, India can overcome these hurdles and stay on track to achieve its renewable energy goals.

Speaking at the launch of the new toolkit for Swachh Survekshan, the Union Minister said, “To acknowledge the exceptional performance of cities in Swachh Survekshan, we are introducing the ‘Super Swachh League’, a competition among the cleanest cities. This reflects our shared commitment to cleanliness, and our continuous innovation keeps the Swachh Bharat Mission a global success even after 10 years. Our focus is on improving quality year after year, with simplified evaluation parameters that ensure clearer data from ULBs and maintain full transparency. This approach strengthens the mission’s reputation and drives ongoing progress in urban cleanliness.

Highlighting the impact of Swachh Survekshan, Secretary, MoHUA, Shri S. Katikithala said, “Swachh Survekshan stands as a remarkable testament to collaboration and collective responsibility, reflecting the nation’s commitment to making cleanliness a way of life. The introduction of the Super Swachh League in this year’s survey serves dual purposes: it encourages top-performing cities to strive for higher aspirational standards, while also motivating other cities to improve and aim for top ranks.”

Again, for the very first time, the cities have been classified into 5 population categories: Very Small, Small, Medium, Big, and Million-Plus. Each category will be assessed based on population and parameters tailored to its specific size and needs. Awards will be given to clean cities in each category. This makes the new Swachh Survekshan inclusive. Even Small Cities will be able to showcase their excellence along with the usual stalwarts like Indore and Surat.

This year, Cleanliness Target Units (CTUs) and adopting Swabhav Swachhata Sanskaar Swachhata – behaviour change in daily lives, have been included in the assessment. The evaluation will focus on key parameters such as eliminating difficult and dark spots, visible cleanliness, establishing Reduce Reuse Recycle Centres, and more. To foster the integration of swachhata values in educational institutions and inspire young minds to adopt cleanliness and sustainability, school assessments have been introduced this year as part of SS. Special focus has been laid on visible cleanliness and waste management at high foot fall tourist spots.

Packaged in a new framework, all indicators in the new SS toolkit have been organized into 10 buckets, with assessment parameters simplified for better understanding by the ULBs.

Advancements in Rapid Sand Filtration Technology

Rapid Sand Filtration: Efficient Water Treatment Method

 This method cleans water quickly and effectively, making it safe for people to drink. Rapid sand filters can process water 60-100 times faster than slow sand filters, helping meet the high demands of urban water supplies.

The process works by passing water through layers of sand and gravel. As the water moves down, dirt and small particles get trapped in the spaces between sand grains. This leaves the water cleaner when it reaches the bottom. Every so often, the filter needs to be cleaned by reversing the flow of water to wash out the trapped dirt.

Rapid sand filtration is popular because it works well and doesn’t take up too much space. It can handle changes in water quality and flow rates, which makes it useful for treating river or lake water that might change with the seasons. Many cities and towns use this method to make sure their tap water is clean and safe to drink.

Overview of Rapid Sand Filtration

Rapid sand filtration is a key water treatment process. It removes particles from water quickly and efficiently. This method has evolved over time to become a standard in many treatment plants.

Defining Rapid Sand Filtration

Rapid sand filtration is a water purification technique. It uses sand beds to filter out impurities. Water flows through the sand at a high rate. This process can clean large volumes of wate.


The system has several parts:

Sand bed

Underdrain system

Backwash mechanism

Water enters the top of the filter. It moves down through the sand. Particles get trapped in the sand layers. Clean water comes out at the bottom.

Rapid sand filters work at higher speeds than slow sand filters. They can handle 2 to 10 gallons per minute per square foot. This makes them great for big water systems.

History and Development

Rapid sand filtration grew from older, slower methods. It became popular in the early 1900s. The need for clean water in growing cities drove its development.

Early filters used only sand. Modern filters often use multiple layers. These might include:

Anthracite coal

Sand

Gravel

Multi-medium filters improved filtration. They could remove more types of particles. This made water cleaner.

Automation changed rapid sand filtration. New systems can clean themselves. This process is called backwashing. It keeps filters working well for longer.

Comparison of Filtration Methods

Sand filtration is a key method for water treatment. Different types of filtration offer unique benefits and drawbacks. Let’s explore the main approaches and how they stack up against each other.

Rapid Sand vs. Slow Sand Filtration

Rapid sand filtration and slow sand filtration are two major techniques used in water treatment. They differ in several key aspects:

Application rate: Rapid sand filtration uses much higher velocities compared to slow sand. Rapid sand filters can process 0.4 to 3.1 m/hr, while slow sand filters handle 0.04 to 0.4 m/hr.

Filtration mechanism: Rapid sand filters work through the entire depth of the filter. Slow sand filters mainly clean water at the surface layer.

Maintenance: Rapid sand filters need frequent backwashing. Slow sand filters require less frequent but more extensive cleaning.

Cost: Rapid sand filtration has higher operating costs but lower land requirements. Slow sand filtration is cheaper to run but needs more space.

Other Filtration Technologies

Beyond sand filtration, there are other methods for water treatment:

Membrane filtration: This includes microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Each type removes particles of different sizes.

Microfiltration can remove particles from 0.05 to 1.0 µm. Reverse osmosis filters out the smallest particles, down to 0.0001 µm.

Diatomaceous earth filtration: This method uses fossilized algae to trap particles. It’s effective for smaller water systems.

Cartridge filtration: These compact filters are good for removing specific contaminants. They’re often used in homes or small-scale applications.

Components of a Rapid Sand Filtration System

Rapid sand filtration systems have three main parts that work together to clean water. These components are crucial for the system to work well and remove impurities.

Filter Media

The filter media is the heart of a rapid sand filtration system. It’s usually made of sand or other materials like anthracite coal. The sand grains are about 0.5 to 1 mm in size.

Filter media traps dirt and small particles as water flows through. The size and shape of the grains affect how well the filter works. Smaller grains can catch more particles but may clog faster.

Some systems use layers of different materials. This can help catch more types of impurities. The depth of the filter media is typically 24 to 30 inches.

Support Layers

Support layers sit below the main filter media. They keep the sand from washing away during filtration and backwashing.

These layers are made of gravel or larger sand particles. They get bigger as you go deeper into the filter. A typical setup might have:

Fine gravel: 1/8 to 1/4 inch

Medium gravel: 1/4 to 1/2 inch

Coarse gravel: 1/2 to 1 inch

The support layers help spread water evenly through the filter. This makes the whole system work better.

Underdrain System

The underdrain system is at the bottom of the filter. It collects the cleaned water after it passes through the filter media and support layers.

This system often has pipes with small holes or nozzles. These let water through but keep the filter media in place. The underdrain also helps during backwashing.

During backwashing, water flows backward through the filter to clean it. The underdrain spreads this water evenly. This helps remove trapped dirt and keeps the filter working well.

The design of the underdrain affects how well the filter works and how long it lasts. Good designs make sure water flows evenly and the filter cleans properly.

The Process of Rapid Sand Filtration

Rapid sand filtration cleans water through several key steps. This process removes impurities and makes water safe to drink.

Coagulation and Flocculation

Coagulation starts the rapid sand filtration process. Chemicals like alum are added to the water. These chemicals make tiny particles clump together.

The water then moves slowly, allowing the clumps to grow bigger. This step is called flocculation. The bigger clumps are easier to remove later.

Mixing paddles or baffles help the clumps form. The speed and time of mixing are important. Too much mixing can break up the clumps.

Sedimentation

After flocculation, the water flows into large tanks. Here, it sits still for a while. This lets the heavy clumps sink to the bottom.

The clumps form a layer of sludge. Clean water stays on top. This sludge is removed regularly to keep the tank clean.

Some plants use special plates or tubes. These help the clumps settle faster.

Filtration

The clearer water from sedimentation goes to the filter beds. These beds have layers of sand and gravel.

As water moves down through the sand, it traps leftover particles. The sand acts like a strainer, catching tiny bits that sedimentation missed.

Over time, the filter gets clogged. Plants clean the filters by backwashing. This means pushing water up through the filter to flush out trapped dirt.

Disinfection

The last step kills any remaining germs. Chlorine is the most common disinfectant. It’s added to the filtered water.

Other methods like UV light or ozone can also work. These kill bacteria and viruses without chemicals.

The water is tested to make sure it’s safe. Then it’s stored in tanks or sent directly to homes and businesses.

Operation and Maintenance

Proper operation and maintenance are crucial for rapid sand filtration systems. These tasks ensure the system runs efficiently and produces clean water consistently.

Backwashing Procedure

Backwashing cleans the filter media by reversing water flow. This process removes trapped particles and prevents clogging. To backwash:

Stop the filtration process.

Close the inlet valve.

Open the backwash valve.

Start the backwash pump.

Monitor the backwash water for clarity.

Stop when the water runs clear.

Close the backwash valve.

Open the inlet valve.

Resume normal filtration.

Rapid sand filtration typically requires backwashing every 24 to 72 hours. The frequency depends on water quality and filter load.

Regular Maintenance Tasks

Regular maintenance keeps the system running smoothly. Key tasks include:

• Daily checks of filter pressure and flow rate. • Weekly cleaning of filter surfaces. • Monthly inspection of valves and pumps. • Quarterly testing of filter media depth and condition. • Yearly replacement of worn parts.

Operators should keep detailed records of all maintenance activities. This helps track system performance and plan for future upgrades. Regular training ensures staff can handle routine tasks and troubleshoot issues effectively.

Applications of Rapid Sand Filtration

Rapid sand filtration is a versatile water treatment method. It cleans water for drinking, industry, and farming. This process removes particles and some microorganisms from water.

Municipal Water Treatment

Rapid sand filtration plays a key role in city water systems. Rapid sand filtration water treatment plants clean large amounts of water quickly. They use higher flow rates than slow sand filters.

These plants often use rapid sand filters as part of a larger system. The filters remove leftover particles after earlier treatment steps. This helps make water safe to drink.

Rapid sand filters in these plants can handle changing water quality. They work well for both surface water and groundwater sources.

Industrial Wastewater Treatment

Many industries use rapid sand filtration to clean their wastewater. It helps remove solid particles from water used in manufacturing.

The process can treat water from food processing, paper mills, and chemical plants. It often serves as a pre-treatment step before more advanced cleaning methods.

Rapid sand filters in industry can be customized. Filter media and flow rates are adjusted to match specific waste types.

Agriculture and Irrigation

Farmers use rapid sand filtration to clean water for crops. It removes sand, silt, and other particles that could clog irrigation systems.

The method helps protect sprinklers and drip irrigation equipment. This leads to more even water distribution in fields.

Rapid sand filters can also clean water from ponds or rivers for livestock. This improves animal health and farm hygiene.

Some large farms have their own rapid sand filtration systems. These systems can treat water from various sources for multiple uses on the farm.

Advancements in Rapid Sand Filtration Technology

Rapid sand filtration has seen major improvements in recent years. These upgrades have made the process more efficient and effective at removing contaminants from water.

Automation and Control Systems

Modern rapid sand filters now use advanced automation. Computer systems monitor and adjust filtration parameters in real-time. This leads to more consistent water quality and less human oversight.

Sensors track key metrics like flow rate, turbidity, and pressure drop. When readings fall outside set ranges, the system makes automatic adjustments. For example, it may trigger backwashing cycles or alter chemical dosing.

Remote monitoring allows operators to check filter performance from anywhere. This improves response times to issues. It also enables predictive maintenance, reducing unexpected downtime.

Rapid gravity sand filtration plants now use SCADA systems. These integrate all filtration processes into one control interface. This holistic view optimizes overall plant efficiency.

Improvements in Filter Media

New filter media materials enhance contaminant removal. Activated carbon layers trap organic compounds and improve taste and odor. Some plants use crushed recycled glass as a sustainable sand alternative.

Multi-media filters combine materials of different sizes and densities. This creates a gradient that captures particles more effectively. A typical layout may include anthracite, sand, and garnet layers.

Specialized coatings on filter media boost performance. Some coatings make the media antimicrobial, reducing biological fouling. Others alter surface charges to better attract specific contaminants.

Researchers are developing new filtration materials to target emerging pollutants. These aim to remove persistent chemicals like PFAS from water supplies.

Environmental Impact and Sustainability

Rapid sand filtration affects water resources and energy use. It offers benefits but also raises concerns about sustainability.

Water Conservation

Rapid sand filtration helps save water. It cleans water faster than slow sand filters. This means less water is lost during the process.

The system can handle large amounts of water quickly. This is good for places that need a lot of clean water.

But rapid sand filters need backwashing. This uses extra water to clean the filter. Some places reuse this backwash water to save more.

New designs try to use less water for backwashing. This makes the whole system more water-efficient.

Energy Efficiency

Rapid sand filtration uses energy to work. Pumps move water through the sand beds. This takes electricity.

Newer systems use gravity to help move water. This cuts down on energy use. Some places also use solar power for the pumps.

The energy use depends on the size of the system. Bigger systems often use more energy, but clean more water.

Some filters now have special materials that remove chemicals. This can save energy by doing more in one step.

Engineers work on making the pumps more efficient. This helps cut down on energy use over time.

Regulations and Standards

Rapid sand filtration is subject to various regulations and standards worldwide. These guidelines ensure safe and effective water treatment across different jurisdictions.

International Standards

The World Health Organization (WHO) provides global standards for rapid sand filtration. These guidelines focus on water quality targets and operational parameters.

Key WHO recommendations include:

Filtration rates between 4-12 m/h

Turbidity removal of 90-98%

Bacterial reduction of 90-99.9%

Many countries adopt WHO standards as a baseline for their national regulations. The International Organization for Standardization (ISO) also offers guidelines for water treatment processes, including rapid sand filtration.

Local Guidelines

In the United States, the Environmental Protection Agency (EPA) sets regulations for rapid sand filtration. These rules are part of the Safe Drinking Water Act.


EPA requirements include:

Maximum filtration rate of 4 gpm/ft²

Turbidity limits of 0.3 NTU in 95% of samples

Continuous turbidity monitoring

States may impose stricter standards. For example, California requires lower turbidity levels in some cases. The EU has its own Drinking Water Directive, which member states must follow. This directive sets parameters for water quality after filtration.

Where the Land Meets the Sea

Mangroves as Guardians of Life and Livelihoods

Posted On: 01 APR 2025 2:36PM by PIB Delhi

As the morning tide gently laps against the shores of Navghar, Vandana Patil steps onto the damp earth of her village’s coastline. She recalls a time when the sea was generous, offering abundant crab and fish catch. But over the years, that generosity faded. "Earlier, we used to see unpredictable crab and fish catch and had to rely on other sources of livelihoods," she says, her voice carrying the weight of years spent worrying about an uncertain future.

a group of people standing in front of a building

The culprit was clear: the unchecked destruction of mangroves. The towering green guardians of the coastline had been silently disappearing, their roots no longer anchoring the land, their dense canopies no longer sheltering marine life. With every tree lost, so too was a piece of the community’s livelihood. Yet, many in Navghar remained unaware of the deep connection between the mangroves and their survival.

Change arrived in the form of a far-reaching initiative. The Government of India, in collaboration with the Green Climate Fund and UNDP, launched a project to enhance climate resilience in India's coastal communities. This initiative, operational across three coastal states-Andhra Pradesh, Maharashtra, and Odisha focused on conserving and restoring marine ecosystems, including mangroves, while creating climate-resilient livelihoods.

Navghar became a symbol of this transformation. In 2021, the project formed a Mangrove Co-Management Committee, bringing together village members, the Gram Panchayat, and women’s Self-Help Groups (SHGs). Their mission was twofold: protect the mangroves and revive local livelihoods. Women, often the most affected by economic instability, were placed at the forefront.

Through structured training, they learned sustainable crab farming techniques, creating new livelihood groups like Healthy Harvest and Wild Crab Aqua Farm. These groups now farm mud crabs over two acres of coastal land while ensuring the protection of mangroves from illegal cutting. The impact was immediate.

“Through our campaigns and drives, we have raised awareness about mangroves and their link to healthy fish catch and livelihoods,” explains Rohan Patil, president of the committee. “People no longer see them as just trees—they see them as protectors.”

By 2023, the once-barren coastline had transformed. The mangroves stood tall, shielding the land from erosion and storms, while the waters teemed with life again. The benefits extended beyond the environment. “The project helped us a lot,” Vandana shares. “Earlier, women worked only seasonally. Now, we have employment throughout the year. Besides, earlier we had to travel far and wide for crab farming; now, we can do it locally.”

What is Mangrove?

A mangrove is a salt-tolerant plant community found in tropical and subtropical intertidal regions. These ecosystems thrive in high-rainfall areas (1,000–3,000 mm) with temperatures ranging from 26°C to 35°C. Mangrove species are adapted to survive in waterlogged soils, high salinity, and frequent tidal surges. They serve as crucial biodiversity refuges and act as bio-shields against extreme climatic events. Additionally, rural populations depend on mangroves for biomass-based livelihoods.

Where the Land Meets the Sea


Mangroves as Guardians of Life and Livelihoods

Posted On: 01 APR 2025 2:36PM by PIB Delhi

As the morning tide gently laps against the shores of Navghar, Vandana Patil steps onto the damp earth of her village’s coastline. She recalls a time when the sea was generous, offering abundant crab and fish catch. But over the years, that generosity faded. "Earlier, we used to see unpredictable crab and fish catch and had to rely on other sources of livelihoods," she says, her voice carrying the weight of years spent worrying about an uncertain future.

The culprit was clear: the unchecked destruction of mangroves. The towering green guardians of the coastline had been silently disappearing, their roots no longer anchoring the land, their dense canopies no longer sheltering marine life. With every tree lost, so too was a piece of the community’s livelihood. Yet, many in Navghar remained unaware of the deep connection between the mangroves and their survival.

India’s Progress in Mangrove Conservation


India has made significant strides in mangrove conservation through a combination of robust regulatory frameworks and targeted promotional initiatives. As per the India State of Forest Report 2023 (ISFR-2023), India’s total mangrove cover stands at 4,991.68 sq. km, constituting 0.15% of the nation’s geographical area. There has been net increase of 363.68 Sq.km (7.86%) in Mangrove cover area of the country in 2023 as compared to 2013 and net increase of 509.68 Sq.km (11.4%) between 2001 and 2023.

West Bengal holds the largest share of the country's mangrove forests, accounting for 42.45% of the total cover, followed by Gujarat (23.32%) and the Andaman & Nicobar Islands (12.19%). Notably, Gujarat has recorded an impressive increase of 253.06 sq. km in mangrove cover between 2001 and 2023, attributed to large-scale plantations, community participation, and public-private partnerships.

Key Regulatory Measures

India has implemented a series of stringent legal frameworks to ensure mangrove protection:

  • Coastal Regulation Zone (CRZ) Notification, 2019 under the Environment (Protection) Act, 1986, categorises mangroves as Ecologically Sensitive Areas (ESAs), restricting activities within a 50-metre buffer zone where mangrove cover exceeds 1,000 sq. m.
  • Mandates compensatory replantation at a 3:1 ratio if mangroves are affected by development.
  • Additional protection under the Wildlife (Protection) Act, 1972Indian Forest Act, 1927, and Biological Diversity Act, 2002, among others.

Key Promotional Initiatives and Achievements

  1. Mangrove Initiative for Shoreline Habitats & Tangible Incomes (MISHTI):
    • Launched on 5 June 2023 to promote restoration and afforestation across 540 sq. km in 9 coastal States and 4 Union Territories.
    • Implementation through convergence funding with the National Compensatory Afforestation Fund Management and Planning Authority (CAMPA).
    • For FY 2024–25, ₹17.96 crore has been allocated to Andhra Pradesh, Gujarat, Kerala, Odisha, West Bengal, and Puducherry for the treatment and restoration of 3,836 hectares of degraded mangroves.
  2. National Coastal Mission – Conservation of Mangroves and Coral Reefs:
    • Financial assistance for the conservation of 38 mangrove sites and coral reef sites across the country.
    • Operates on a 60:40 cost-sharing model between the Centre and States.
    • 8.58 crore released to seven coastal States during 2021–23 for mangrove conservation.
  3. GCF-ECRICC Project (Green Climate Fund – Enhancing Coastal Resilience of Indian Coastal Community):
    • Active since 2019 in Andhra Pradesh, Maharashtra, and Odisha.
    • Aims to restore and conserve 10,575 hectares of mangroves.
    • As of 2024, 3,114.29 hectares have been successfully restored.

 

Why Mangroves Matter


Mangroves: Nature’s Carbon Vault

 

As per World Wildlife Fund mangroves store 7.5–10 times more carbon per acre than tropical forests. Their loss contributes to 10% of global greenhouse gas emissions from deforestation. These coastal forests hold over 21 gigatons of carbon87% of which is locked in the soil beneath their roots. Restoring just 1.6 million acres of lost mangrove forests could capture an additional 1 gigaton of carbon.


 

A Tidal Shift Towards Sustainability

Navghar’s transformation reflects a broader movement sweeping across India’s coastline where communities are not just adapting to change but actively shaping it. The revival of mangroves, once overlooked and degraded, now stands as a testament to collective action and inclusive development.

Through the integration of science, policy, and grassroots participation, India is forging a path where ecological restoration directly uplifts local economies. Women like Vandana Patil are no longer passive witnesses to environmental loss but active custodians of their natural heritage, securing livelihoods while nurturing resilience.

This shift marks more than environmental progress. It signals a future where nature-based solutions become central to climate action and communities, once vulnerable, emerge as champions of sustainable change.
