One Nation, No Return, Brain Drain,

One Nation, No Return, Brain Drain:

India’s Citizenship Exodus and the High Price of Denying Dual Citizenship and Research Funding 

Dr. Chandrashekhar M Biradar | 24 July, 2025

The Alarming Trend: Over 2 Lakh Indians Renounced Citizenship in 2024

In 2024 alone, 2,06,378 Indians gave up their Indian citizenship — a staggering figure revealed in the Rajya Sabha by the Minister of State for External Affairs, Kirti Vardhan Singh. This follows a continuing trend:

• 2024: 2,06,378
• 2023: 2,16,219
• 2022: 2,25,620
• 2021: 1,63,370

In the past decade, nearly 2 million Indians have renounced their citizenship — not out of disloyalty, but out of legal compulsion when they adopted the nationality of another country for education, career, or personal security.

A Global Citizenry India No Longer Owns

Most of these individuals became citizens of nations like the USA, Canada, UK, Australia, Germany, and France, ˝countries that allow and even encourage dual citizenship. But India is one of the only major countries in the world that does not allow its citizens to hold dual nationality. If an Indian becomes a citizen of another country, they must surrender their Indian passport. The result? A legal severance of their connection to Bharat. 

Surrender and Renunciation of Indian Citizenship applies only to applicants of Indian Origin. Under The Indian Citizenship Act, 1955, Persons of Indian Origin is not allowed DUAL Citizenship. If a person has ever held an Indian Passport and has obtained the Passport of another country, they will be required to surrender their Indian Passport immediately after gaining another Country’s nationality.

“We proudly call the world Vasudhaiva Kutumbakam, World is One Family, yet refuse to allow our citizens to legally remain part of that global family. We praise Nobel Prize winners, tech CEOs, inventors, and researchers of Indian origin as ‘Indian successes’ — but they are no longer Indian citizens. India celebrates them, but does not recognize them.”

The Great Indian Brain Drain -A Crisis of Policy

And it’s not just numbers. Most of the Indians who gave up their citizenship are millionaires, inventors, entrepreneurs, doctors, engineers, researchers, and high-performing professionals. These are people who worked hard, paid taxes, created technologies, generated jobs, and contributed meaningfully to India and the world.

Just imagine the collective loss:

• Patents not filed in India
• Startups registered abroad
• Research papers published from foreign institutions
• Awards, honours, and breakthroughs attributed to other nations
• Revenue, innovation, and recognition — permanently lost

India isn’t just losing its citizens, it’s losing a generation of global influence, enterprise, and talent.

 China vs India: Two Paths, One Question

While India enforces a no-return policy on citizenship, China launched the ‘10,000 Talent Return Program’. Through it, Chinese nationals abroad were invited and incentivized to return, offering them better or equivalent opportunities to serve their homeland.

China recognized the brain drain early and turned it into brain circulation, empowering returning citizens to lead in science, defence, education, and tech.

Today, China leads India in:

• Number of patents filed annually
• Nobel recognitions and international awards
• Scientific publications
• GDP and global trade leverage
• And its strategic influence over AI, semiconductors, and green tech

A Personal Reflection

I had the privilege of living and working in the United States for nearly a decade, holding a U.S. Green Card and having the option to acquire American citizenship. But I made a conscious and heartfelt decision not to give up my Indian citizenship. I surrendered my Green Card and chose to return to India—to serve the land that shaped me, and to contribute to its journey toward global leadership.

However, not everyone is in a position to make that choice—especially the younger generation of talented professionals, researchers, and entrepreneurs. They are often forced to weigh their deep-rooted loyalty against the practical need for world-class opportunities, institutional recognition, and professional dignity. The reality is stark: if India cannot offer them the best scientific, academic, and career platforms, they will not return—and many will not stay.

This leads to a tragic and persistent outcome: we lose our brightest minds, our most hardworking and visionary citizens, not due to lack of patriotism, but because of outdated policies that no longer reflect the aspirations of a globally connected Bharat. We cannot afford to let rigid laws from the 1950s define the future of 2047.

Dual Citizenship, Innovation & Diaspora Policy

The comparison highlights that the United States treats its diaspora as a strategic national asset, providing legal continuity through dual citizenship, full rights, and structured reintegration programs that enable overseas Americans to contribute both at home and globally. In contrast, India, despite its deep emotional and cultural ties to its global diaspora—lacks the legal frameworks and modern policy mechanisms necessary to fully leverage their potential. The absence of dual citizenship in India effectively severs millions of capable, loyal, and globally positioned Indians from participating in the nation’s development, innovation ecosystem, and strategic interests at a time when their contributions could elevate Bharat’s global standing.

Invest in Fundamental Science to Prevent Brain Drain

One of the most urgent challenges facing India’s knowledge economy is the lack of sustained investment in basic and fundamental research infrastructure, which remains a critical driver for innovation, deep technology, and national competitiveness. While India is rich in human talent, hardworking youth and bestowed with ancient scientific wisdom, it continues to face a shortfall in research funding and high-quality institutional opportunities, infrastructure, especially for young, talented minds in science and technology.

Every year, India sees thousands of top graduates and best brains in science, physics, mathematics, biology, AI, and engineering move abroad, not for better salaries alone, but for access to world-class laboratories, research ecosystems, mentorship, and freedom to pursue curiosity-driven inquiry, like I left India in 2000s to seek best opportunities and ecosystem to peruse my dream. But one think was very clear in my mind that I will return to India one day, that opportunity come in 2022 while many even better opportunities awaiting elsewhere. 

In contrast, countries like the USA, Germany, Denmark, China, Israel, etc invest substantially in basic science as a strategic foundation for national innovation. China’s focus on research universities and return-talent programs has made it a global leader in deep tech patents, quantum computing, semiconductors, and space science.

To truly become Atmanirbhar and globally competitive, India must elevate fundamental science to a national mission, with:

• A 5x increase in public funding for basic and interdisciplinary research
• Creation of young investigator grants and return fellowships and very attractive talent return program for overseas Indian scientists and innovators. 
• Establishment of research clusters in Tier-II and rural universities to promote distributed innovation
• Integration of Indian knowledge systems (IKS) with frontier science for globally distinctive breakthroughs.
• India bestowed with all the needed inherent talent to develop most cost effective, low emission, and sustainable production systems in all sectors with appropriate enabling environment to lead the global green growth with local actions.  

Without this foundational commitment, even the best diaspora re-engagement policies may fall short, as talent follows purpose, infrastructure, and intellectual freedom.

What Needs to Change?

India’s Overseas Citizen of India (OCI) scheme has been a positive step in acknowledging the emotional and cultural ties of our global diaspora. However, it remains an incomplete bridge, granting visa-free travel and residency but denying political rights, public sector opportunities, voting power, and full civic inclusion.

If India truly aspires to become a Vishwa Guru, a guiding force in the 21st century grounded in both Sanatan values and technological progress, it must boldly reimagine its citizenship framework to reflect the realities of global mobility, diaspora engagement, and knowledge-based economies.

Policy Recommendations for a Future-Ready Bharat

1. Recognize Dual Citizenship for Global Indians
   Amend the Indian Citizenship Act to allow dual citizenship for qualified emigrants, investors, professionals, and scientists, particularly those in countries with reciprocal arrangements and strategic alignment.
2. Launch a ‘Global Indian Talent Return Mission’
   Create a flagship program to attract and reintegrate high-achieving Indian-origin individuals through prestigious return fellowships, incentives, academic and startup fast-tracks, and dignified institutional roles.
3. Reform Nationality Laws for the 21st Century
   Replace the binary legal framework with one that honours transnational identity, contribution, and intent, recognizing that loyalty today is demonstrated through service—not just paperwork.
4. Enable Re-Acquisition of Indian Citizenship
   Introduce a clear, time-bound, and inclusive pathway for those who once renounced Indian citizenship but now wish to return and contribute to national development.
5. Reframe the Diaspora as Permanent Partners
   Stop viewing overseas Indians as “former citizens” and instead institutionalize them as lifelong ambassadors, co-creators, and policy stakeholders in India’s economic, scientific, and cultural progress.

The World is Moving Forward, Will India?

The decision of over 2 lakh Indians to renounce their citizenship in a single year is more than a bureaucratic statistic. It is a signal, a mirror held up to our outdated policies on identity, talent, and global integration.

While most advanced nations have embraced dual nationality as a tool of soft power and strategic advantage, India continues to enforce a binary model, pushing out its best minds and making return a legal impossibility.

If Bharat is to truly realize its ancient ethos of Vasudhaiva Kutumbakam and its modern ambition of becoming a Viksit Rashtra by 2047, we must urgently rethink what it means to be Indian, Bharatiya, not just by birth, but by choice, contribution, and conviction.

The time for this transformation is now! 

Plastic-Free Natural Pond Lining Options

Plastic-Free Pond Lining for Regenerative Agriculture and Water Stewardship
Dr. Chandrashekhar M. Biradar | Earth System Scientist & Lead-Global Green Growth 

As the world seeks sustainable solutions to the growing crises of water scarcity, microplastic pollution, and ecological degradation, it is time we turn to time-tested, nature-based approaches. One such solution lies beneath our feet — in the way we build and line ponds. It’s time to move beyond plastic.

A Global Call from Environment Day 2025: Plastic-Free Agriculture

During the recent Global Conference on Plastic-Free Agriculture and Environment Day 2025, held under the banner of Reclaiming the Earth, we brought together voices from science, policy, farming communities, and youth leaders. The message was clear:

• Plastic in soil and water must be phased out.
• Living water systems must be restored.
• Agriculture must go plastic-free — from seed to soil to storage.

A key resolution from the event was the promotion of natural pond linings as an ecological and scalable alternative to plastic sheets used in farm ponds. Plastic liners, while cheap in the short term, are now known to cause long-term harm — from microplastic leaching to ecological dead zones and economic burdens due to short lifespans and replacement needs.

Let us explore the plastic-free path forward.

Why Say No to Plastic Pond Liners?

Despite their quick-fix appeal, synthetic liners like HDPE and PVC have major drawbacks:

• Microplastic Pollution: Degrades under UV and heat, contaminating soil and water.
• Thermal Stress: Plastic heats quickly, disrupting aquatic life.
• Short Lifespan: Typically last 5–10 years, creating replacement and disposal issues.
• No Ecosystem Integration: Blocks microbial life, plant roots, and groundwater recharge.

In contrast, natural pond linings offer living solutions that regenerate the land and recharge our aquifers.

Seven Plastic-Free Natural Pond Lining Options 

1. Compacted Clay Lining
Compacted clay lining is among the oldest and most ecologically harmonious methods of sealing ponds and water harvesting structures. This method relies on the natural sealing properties of clay-rich soils especially those with 30–50% clay content to create a semi-impermeable barrier that retains water effectively while supporting the microbial and biological life essential for a healthy pond ecosystem.

Why Clay Works: Clay particles are microscopic plate-like structures that, when moistened and compacted, align tightly, reducing pore spaces and drastically limiting water infiltration. The result is a dense, slow-permeating seal that mimics the natural pond bottoms found in traditional village tanks and seasonal wetlands

Step-by-Step Process of Compacted Clay Lining

Step	Description
1. Site Cleaning	Remove debris, organic material, and sharp stones from pond base and embankments.
2. Soil Testing	Ensure clay content is at least 30% using field jar sedimentation or lab testing.
3. Layering	Spread 10–15 cm thick moist clay-rich soil over the base.
4. Moisture Conditioning	Add water to achieve plastic consistency—neither too dry nor sticky.
5. Compaction	Use mechanical rollers, wooden rammers, or cattle trampling to compress the layer.
6. Repeat	Add 2–3 additional layers (total thickness 30–45 cm), compacting each layer well.
7. Final Sealing	Apply a smooth top layer and gently slope toward center for drainage.

Ecological and Functional Benefits

• Water Retention: Clay seals prevent rapid percolation, ensuring seasonal and year-round water availability.
• Biodegradable and Local: Uses locally sourced soil, avoiding synthetic materials or imported inputs.
• Supports Microbial & Aquatic Life: Allows slow seepage and temperature buffering, supporting soil microbes, beneficial bacteria, aquatic flora like lotus and azolla, and fauna like frogs and insects.
• Groundwater Recharge: Allows controlled percolation at the base while reducing horizontal seepage, recharging shallow aquifers.
• Cost-Effective: Ideal for MGNREGA, watershed, and farmer-led pond construction without dependence on plastic imports.

Limitations and Mitigation

Challenge	Solution
Cracking during dry periods	Add small % of organic material like straw or cow dung to prevent fissures
Erosion on bunds	Use stone pitching or plant vetiver grass along edges
Clay unavailability in site soil	Transport from nearby catchment or use bentonite-clay mix

Estimated Clay Requirement Per Pond

(For a 20m x 20m pond with 1.5m depth)

Parameter	Value
Base Area	400 m²
Side Slopes + Buffer	~200 m²
Total Area to Line	~600 m²
Clay Thickness	30 cm (0.3 m)
Total Volume of Clay	180 m³
Soil Required (wet weight)	~250–300 tons (depending on moisture content)

2. Bentonite Clay Amendment: The Self-Healing Natural Sealant

Bentonite clay is a naturally occurring volcanic-origin swelling clay composed predominantly of sodium montmorillonite. When hydrated, it expands up to 10–15 times its dry volume, forming a dense, gel-like barrier that seals pores, cracks, and fissures in the soil. This makes it an ideal plastic-free alternative for lining new ponds or repairing existing leaking ponds, especially where local soil lacks sufficient clay content.

Why Bentonite Works

The unique structure of bentonite allows it to:

• Absorb water and swell, blocking voids and preventing seepage
• Retain its structure under pressure, resisting punctures and erosion
• Self-heal minor cracks and shifts, maintaining long-term impermeability

This hydraulic sealing capacity makes bentonite comparable to engineered geosynthetic liners, but with the added benefits of biodegradability, affordability, and ecological compatibility.

Application Methods for Pond Sealing

There are two common approaches to apply bentonite clay in farm ponds:

A. Blanket Method (for New Ponds)

1. Prepare surface by leveling and removing organic matter
2. Apply bentonite at 1–2 kg per square meter (adjust based on soil type)
3. Mix thoroughly with 5–10 cm of topsoil using a rotavator or spade
4. Compact the layer using rollers or rammers
5. Add water gradually to activate swelling and seal formation

B. Sprinkle Method (for Leaking Ponds)

1. Lower pond water to expose leaking areas
2. Sprinkle bentonite powder directly on the affected zones (1–1.5 kg/m²)
3. Refill with water slowly to allow clay to settle and swell
4. Monitor for 7–10 days; leaks typically reduce or stop completely

Bentonite Dosage Recommendations

Soil Type	Recommended Dosage (kg/m²)
Sandy Soil	2.5–5.0 kg
Sandy Loam	2.0–3.5 kg
Loam/Clay Loam	1.5–2.0 kg
Clay-Rich Soil	1.0–1.5 kg

Note: Dosage may vary depending on pond depth, size, and seepage intensity.

 Ecological and Functional Benefits

✔️ Self-Healing Ability: Automatically seals small cracks or root penetrations over time
✔️ Natural & Non-Toxic: Safe for fish, livestock, and aquatic plants
✔️ Minimal Maintenance: Requires no synthetic liner or major structural reinforcement
✔️ Reusable: Can be replenished or mixed with site soil to restore old ponds
✔️ Supports Biological Activity: Unlike plastic, allows microbial life to thrive at the pond-soil interface

Use Case Example: In Andhra Pradesh’s semi-arid Rayalaseema region, farmers under the Community Natural Farming program have successfully sealed leaking ponds using the sprinkle method with bentonite, enabling water retention for 4–6 months even during lean rainfall periods — all without plastic sheets.

Points to Consider

Limitation	Mitigation Strategy
High cost in remote regions	Use selectively on leaking zones only
Requires moisture to activate	Pre-wet soil or apply during monsoon
Not effective in flowing water	Best for static ponds and farm tanks

Integration with Other Natural Techniques

For best results, combine bentonite amendment with:

• Compacted clay base (in dual lining approach)
• Vetiver-stabilized embankments
• Biochar mix for long-term adsorption and filtration
• Gobar-mitti surface coat for microbial richness

This multi-layered, living pond design ensures both ecological sustainability and long-term structural resilience.

3. Gobar-Mitti Bio-Lining (Cow Dung + Straw)

Gobar-Mitti Lining is a classical indigenous technique that combines cow dung, clayey soil, and agricultural straw(usually rice straw or husk) to create a natural, breathable, and ecologically active pond lining. Practiced across India for centuries in tanks, kunds, and baoris, this method not only retains water effectively but also nurtures the microbial and aquatic life vital for a thriving water body.

Why the Blend Works: Science of a Living Liner

The clay offers sealing strength through fine particle compaction.
Cow dung contributes natural enzymes, beneficial microbes, and colloids.
Straw/husk acts as structural binder and anti-crack reinforcement.
Together, this triad forms a bio-cemented matrix that mimics natural wetland substrates.

Furthermore, mild algal growth over time forms a biological sealing film that enhances water retention, prevents erosion, and creates habitat for microorganisms, aquatic insects, and young fish—strengthening the liner both structurally and ecologically.

Synergistic Benefits of Algal Colonization

Once water is filled into the pond:

• A thin mat of green algae and cyanobacteria develops naturally over the Gobar-Mitti layer.
• This biofilm acts like a living skin—plugging micro-porosity, regulating oxygen, and reinforcing the integrity of the lining.
• It supports the emergence of plankton, snails, and other flora/fauna that form the base of the aquatic food web.
• The photosynthetic layer aids in water purification and moderating pH and temperature extremes.

This is in sharp contrast to plastic liners, which inhibit biological colonization and reduce the ecological richness of ponds.

Step-by-Step Application Process

Step	Activity
1. Material Preparation	Mix fresh cow dung, sieved clay-rich soil, and chopped straw or rice husk in 1:2:1 ratio. Add water to create a smooth plaster-like paste.
2. Site Preparation	Clean and level the pond base and embankments. Remove stones and debris.
3. Layering	Apply 2–3 thin coats (1–2 cm each) of the gobar-mitti mixture. Allow partial drying between each layer.
4. Curing	Let the final coat dry under partial shade for 3–5 days. This step is essential to ensure binding and crack resistance.
5. Filling and Maturation	Fill the pond slowly to promote algal colonization and liner consolidation. Avoid overfilling in the first week.

Lifespan	1–2 years, renewable	5–10 years, non-renewable
Cost	Very Low (local inputs)	High (market purchase)
Ecological Integration	High	Very low
Biodegradability	100%	0%
Maintenance	Easy and local	Specialized and costly

Cultural, Spiritual & Ecological Resonance

In Vedic and Agamic traditions, gomaya (cow dung) is considered sacred and purifying, symbolizing the cycle of life, fertility, and balance with nature. Lining ponds with gobar-mitti not only revives this wisdom but also provides modern, evidence-backed benefits that align with sustainable agriculture and climate resilience.

Integration with Other Nature-Based Techniques

For enhanced durability and multifunctionality, Gobar-Mitti lining can be synergized with:

• Vetiver- or bamboo-stabilized bunds
• Bentonite patching for high-seepage zones
• Biochar-mixed base layer
• Water-filtering inlet traps using pebbles and sand

The Gobar-Mitti lining system is not just a method—it is a manifestation of living design.
It seals, breathes, feeds, heals, and transforms a pond into a regenerative ecosystem.

“A pond that holds water is useful. A pond that holds life is sacred.”

4. Lime-Stabilized Soil Lining: A Durable and Low-Cost Natural Sealing Technique for Semi-Arid Zones

Lime-stabilized soil lining is a time-tested geotechnical technique that enhances the water-holding capacity of local soils by reducing their permeability through lime or pozzolanic material incorporation. By mixing agricultural lime (CaO or Ca(OH)₂) or fly ash into the pond base and bund soil, farmers can achieve a semi-impermeable, firm, and erosion-resistant pond lining — ideal for semi-arid and drought-prone landscapes, where resource constraints demand cost-effective, locally available, and scalable solutions. 

The Science Behind Lime Stabilization

When lime or fly ash is mixed with soil:

• Clay particles flocculate (clump), reducing porosity
• Pozzolanic reactions occur, forming cementitious compounds like calcium silicate hydrates (CSH) and calcium aluminate hydrates (CAH)
• This leads to improved compaction, strength, and water resistance

The result is a stable, hardened soil matrix that retains water efficiently while resisting erosion and degradation.

Step-by-Step Application

Step	Description
1. Soil Selection	Use fine-grained soil with moderate clay content (20–35%)
2. Lime/Fly Ash Mixing	Add agricultural lime (4–8% by weight) or fly ash (8–12%) to loosened soil
3. Moisture Conditioning	Sprinkle water and mix thoroughly to form a moist, consistent layer
4. Layering and Compaction	Apply 2–3 layers of 10–15 cm thick lime-treated soil, compact each with rammers/rollers
5. Curing	Let it cure for 3–7 days, keeping the surface moist for chemical bonding to set in

Note: Fly ash should only be used from certified low-toxicity sources (Class C fly ash preferred).

Benefits of Lime-Stabilized Soil Lining

• Durable and Long-Lasting
  Withstands weathering, drying–wetting cycles, and bund slippage
• Low-Cost and Locally Adaptable
  Requires only lime/fly ash and soil—minimal external materials
• Improves Soil Health in Non-Lining Areas
  Stabilized bunds reduce erosion and support vegetation over time
• Ideal for Arid and Semi-Arid Regions
  Works well where bentonite or clay is unavailable or costly
• Safe and Non-Toxic
  When applied in correct proportions, poses no harm to aquatic ecosystems

Use Cases in India and Beyond

• In Rajasthan and Telangana, lime-treated pond bunds under MGNREGA have improved water retention by over 30–50% compared to untreated soils
• In Sahelian Africa, lime-soil combinations are used to line rainwater harvesting pits, improving storage during long dry seasons
• In Bundelkhand, a pilot project using lime fly-ash soil blend reduced seepage losses in check dams by 40–60%

Comparative Snapshot

Feature	Lime-Stabilized Lining	Plastic Liner	Compacted Clay
Cost	Low	High	Moderate
Lifespan	10–15 years	5–10 years	10–12 years
Ecological Compatibility	High	Low	High
Ease of Repair	Moderate	Difficult	Easy
Suitability for Drylands	High	Low (cracks with heat)	High

---

Points to Consider

Limitation	Mitigation
May crack under extreme heat	Add organic matter (e.g., straw or dung) to mix
Requires proper mixing and curing	Train local masons or SHG members
Not suited for sandy soils alone	Combine with clay/silt for effective stabilization

---

Integration in Ridge-to-Reef Designs

Lime-stabilized soil lining is best used in:

• Bunds and embankments
• Bottom lining in combination with clay or bentonite
• Runoff catchment zones
• Contour trenches and percolation tanks

Pairing it with vetiver grass planting, biochar addition, or gobar-mitti coatings can yield multifunctional outcomes—improving structural resilience, water quality, and ecological value.

5. Stone Pitching with Soil Grouting: A Structural-Ecological Hybrid for Resilient Pond Embankments

Stone pitching with soil grouting is a robust earth-engineering technique used to stabilize pond bunds, sidewalls, and inlet–outlet structures. It involves lining the inner slope and base of the pond with natural stones, carefully arranged and grouted with a binding mix made of clay, lime, and/or cementitious material. This hybrid design provides both mechanical strength and ecological harmony, ideal for ponds in erosion-prone, undulating, or rocky terrains.

Why Stone Pitching Works

• Stones act as armor against wave action, livestock movement, and rain splash
• Soil-lime grout fills the gaps, preventing water from seeping through loose stone packing
• Gradual water movement through the interface supports controlled recharge and microbial activity

The system functions like a permeable yet stable lining, ideal for natural farming ponds, check dams, and community tanks requiring longevity and minimal maintenance.

Step-by-Step Implementation

Step	Action
1. Site Preparation	Excavate and level the embankments or sloped pond base; clear loose soil and debris
2. Stone Selection	Use medium-sized stones (6–20 cm), flat-sided preferred for tight packing
3. Grout Preparation	Mix 60% clay + 30% lime + 10% sand or ash (or use 4:1 soil to hydrated lime)
4. Pitching	Lay stones by hand in interlocking pattern, starting from base upward
5. Grouting	Pour or inject grout mixture into joints and compact; apply final slurry coating if needed
6. Curing	Allow 3–7 days of partial drying and moisture maintenance for setting

For high-load zones (e.g., tank inlets, spillways), add larger foundation stones or stone masonry blocks.

Ecological and Functional Benefits

• Prevents Erosion & Wave Damage
  Protects pond walls from rainfall runoff, livestock trampling, and wind-induced waves
• Stabilizes Earthen Embankments
  Reduces bund failure risk and enhances pond longevity
• Improves Percolation with Control
  Porous stone-grout interface allows gradual recharge into subsoil layers
• Ecological Niche Creation
  Micro-gaps between stones serve as habitat for beneficial aquatic organisms
• Supports Vegetation Establishment
  Roots of grasses like vetiver, lemongrass, or local species find anchorage among stones

Design Recommendations

Pond Size	Stone Thickness (slope area)	Suggested Grout Depth
< 20 m²	15–20 cm	3–5 cm
20–100 m²	20–30 cm	5–8 cm
>100 m²	30–45 cm	8–10 cm

Combined Applications

This technique pairs well with:

• Compacted clay base for the bottom lining
• Bentonite patching at seepage-prone zones
• Gobar-mitti or biochar coatings on top layer
• Vegetative bunds with native or medicinal grasses

This makes the pond multifunctional—resilient to stress and supportive of ecological productivity.

Use Cases and Field Success

• In Karnataka’s semi-arid districts, stone-pitched tanks have withstood heavy monsoon flows and high cattle movement
• MGNREGA-built water structures in Bundelkhand and Marathwada feature this method to reinforce desilting and renovation works
• In Nepal’s hill ponds, this technique is blended with spring-box recharge pits, enhancing water availability for 6–8 months annually

Performance Snapshot

Feature	Stone Pitching + Grouting	Plastic Liner
Structural Stability	Very High	Low (prone to tearing)
Water Holding Capacity	High (with compact base)	High initially
Recharge Potential	Moderate	Very Low
Lifespan	15–25 years	5–10 years
Habitat Support	High	None
Maintenance Cost	Low	High (repair, disposal)

 

Points to Consider

Challenge	Solution
Initial labor intensity	Mobilize MGNREGA/SHG workforce
Grout drying in hot zones	Use partial shade/netting or early morning work
Material sourcing in plains	Use laterite or broken bricks as alternatives

Traditional Roots and Local Knowledge

This method resonates with ancient Indian hydraulic systems, including:

• Kere bunds of Karnataka
• Stepwells (baoris) of Rajasthan
• Phad irrigation tanks of Maharashtra

Reviving it with low-carbon grouting mixes ensures continuity of jal shilp kala (traditional water engineering) in today’s regenerative agriculture frameworks.

6. Vetiver Root Lining: A Living, Self-Renewing Bioengineering Shield for Pond Stability and Ecological Health

Vetiver root lining is a nature-based bioengineering technique that leverages the extraordinary root architecture of Vetiver grass (Chrysopogon zizanioides) to stabilize pond bunds, prevent erosion, and reduce seepage. Unlike synthetic barriers or rigid structures, vetiver systems evolve, deepen, and strengthen with time—adapting to climate stress, supporting biodiversity, and purifying water. Planted strategically along pond embankments, spillways, and catchment areas, vetiver creates a “green wall” with deep roots—up to 3–4 meters vertically, binding soil and acting as a biological filter and living barrier.

Why Vetiver Works

• Vetiver roots grow vertically, not laterally, making them ideal for bunds without competing with nearby crops
• Their high tensile strength (equal to mild steel wire) holds soil particles even during extreme rainfall events
• The dense culm structure at the base reduces wind and water erosion
• Its rhizosphere enhances soil microbial activity and water filtration

Establishing Vetiver Root Lining Around a Pond

Step	Action
1. Trench Preparation	Dig a shallow trench (10–15 cm deep) 0.5–1 meter from pond edge
2. Spacing and Planting	Plant vetiver slips (tillers) 10–15 cm apart for a continuous hedge

7. Biochar-Enhanced Clay Lining: A Nature-Positive Innovation for Water Security and Soil Regeneration

Biochar-enhanced clay lining is a regenerative, climate-smart method that combines clay-rich soil with biochar—a porous, carbon-rich material derived from pyrolyzed biomass—to form a composite pond lining that excels in water retention, microbial colonization, and carbon sequestration. This method not only prevents excessive seepage but transforms the pond base into a living bio-reactor that filters, buffers, and stores both water and carbon. 

By merging traditional compacted clay techniques with modern soil microbiome science, this lining method offers a long-lasting, multifunctional solution for ponds in arid, semi-arid, and degraded landscapes.

Why Biochar + Clay Works

• Clay provides structural sealing through fine particle compaction
• Biochar adds porosity, allowing microbe colonization, slow percolation, and improved water-holding capacity
• The porous carbon matrix holds water up to 5–7 times its weight and acts as a reservoir for nutrients and beneficial bacteria
• Acts as a natural filter, reducing contaminants and improving water quality over time

Application Process

Step	Activity
1. Biochar Preparation	Use well-pyrolyzed (350–550°C) biochar from woody/agri residues; crush to fine granules
2. Soil-Biochar Mixing	Mix at 5–10% biochar by volume with clay-rich soil
3. Moisture Conditioning	Add water and knead the mix to a paste-like consistency
4. Layering and Compaction	Apply 2–3 layers (10–15 cm each), compacted manually or mechanically
5. Optional Inoculation	Biochar can be inoculated with compost tea, cow urine, or slurry to seed microbial life before application

 

Ecological and Functional Benefits

• Improves Water Retention
  Biochar’s internal pore network enhances clay’s capacity to retain moisture
• Enhances Microbial Activity
  Microbes colonize biochar, forming biofilms that aid nutrient cycling and organic matter stabilization
• Natural Water Filtration
  Adsorbs heavy metals, pathogens, and toxins, improving water quality for aquaculture or irrigation
• Long-Term Carbon Storage
  Each ton of biochar can sequester ~2.2–2.6 tons of CO₂ equivalent for centuries
• Soil Health Recovery
  When ponds dry seasonally, the biochar-lined soil enriches the pond bed, increasing its fertility

Performance Highlights

Parameter	Biochar-Clay Lining	Plain Clay Lining	Plastic Liner
Water Retention	Very High	High	Very High
Microbial Activity	Excellent	Moderate	None
Climate Mitigation	Strong	Low	Negative (plastic waste)
Cost	Moderate (initially)	Low	High
Ecological Compatibility	Very High	High	Low

 

Field Applications and Use Cases

• Araku Valley, Andhra Pradesh: Tribal farmers use biochar-lined check ponds in agroforestry plots, reducing irrigation needs by ~30%
• Rajasthan Desert Zones: Biochar-clay liners used in rooftop rainwater tanks reduce leakage and improve water taste
• Sub-Saharan Africa: Adopted in FAO/UNCCD dryland water harvesting projects for dual water-carbon conservation

Recommended Mix Ratio (for Lining Applications)

Component	Proportion (by volume)
Clayey Soil	90–95%
Biochar (fine)	5–10%
Optional Add-ons	Cow dung slurry or compost tea (for inoculation)

 

Integration in Regenerative Designs

Best used in conjunction with:

• Gobar-mitti surface finish for biological sealing
• Vetiver embankments to prevent edge erosion
• Contour bunds and micro-catchments to enhance recharge
• Food forest zones that utilize the pond water and runoff

This makes the pond not just a water-holding structure, but a living, climate-positive system contributing to soil regeneration and local water cycles.

Rooted in Tradition, Aligned with Innovation

While biochar is gaining global attention today, charcoal-amended soils (Terra Preta) have been known in ancient Vedic agriculture and Amazonian systems. Reviving this knowledge with modern soil science can offer scalable, nature-compatible water solutions in India’s drylands.

Ecological & Economic Comparison

Feature	Plastic Liner	Natural Lining
Lifespan	5–10 years	20+ years with maintenance
Soil and Water Health	Negative	Positive
Ecosystem Integration	Low	High
Cost Over 10 Years	High	Low
Groundwater Recharge	Nil	Moderate and beneficial

A Return to Living Systems

In regenerative farming, water bodies must do more than hold water. They must breathe, host life, recharge aquifers, purify runoff, and nourish the land. Plastic prevents this. Natural linings, on the other hand, enable it.

With innovations in bio-cementation, clay science, soil biology, and plant-root systems, natural pond construction is both scientifically robust and rooted in our ecological traditions.

Policy and Practice: The Way Forward

• Integrate natural pond lining techniques into MGNREGA, Jal Shakti Abhiyan, and PMKSY
• Create model ponds at every KVK, Krishi Vigyan Kendra, and organic cluster
• Ban plastics in certified organic and eco-sensitive zones
• Train local youth and engineers in natural pond construction
• Provide incentives for community ponds with ecological services

Conclusion: Water is Sacred, Let it Flow Naturally

Let us remember, in Bharatiya parampara, water bodies were never lined with plastic. They were created as sacred ecosystems—kunds, pushkarnis, tanks, and johads—each designed with local materials, community wisdom, and spiritual care.

In going plastic-free, we are not going backwards — we are going back to our roots to build the future.

Let our ponds be living waters, not plastic pits.
Let every drop nurture not just crops, but ecosystems and livelihoods.
Let every farm pond be a symbol of regenerative dharma.

Join the movement for Plastic-Free Agriculture.
Let’s build 1 million natural ponds across Bharat before 2030.

Role of Farmer Producer Organizations (FPOs) in India’s Agri-Food System Transformation

Role of Farmer Producer Organizations (FPOs) in India’s Agri-Food System Transformation 

India stands at a critical juncture in its agrarian journey. Despite being the world’s largest producer of milk, pulses, and spices, and a global agricultural powerhouse, the average Indian farmer remains trapped in a cycle of low income, high risk, and uncertain futures. With over 86% of cultivators being small and marginal farmers, and millions more working as landless farm laborers, the promise of rural prosperity remains largely unfulfilled.

In this context, Farmer Producer Organizations (FPOs) emerged as a bold institutional innovation—intended to democratize access to markets, services, capital, and technology. They were envisioned not just as collectives, but as the new rural enterprise model to transform agriculture into a viable and dignified livelihood.

A growing perception questions their effectiveness—“Are FPOs a failed experiment?”
Even worse, many now see FPOs as mere input dealers or subsidy channels, far removed from the original vision of agrarian transformation.

It is time to confront this challenge honestly—and reframe the discourse.

Karnataka’s Center for Excellence for FPOs: A National First in Farmer-Led Transformation

The Government of Karnataka has established India’s first state-level Center for Excellence for Farmer Producer Organizations (CoE-FPO), a pioneering initiative designed to go beyond FPO formation and focus on long-term empowerment, market integration, and professional governance of farmer collectives.

Unlike traditional scheme-based support, this Center serves as a dedicated ecosystem enabler, offering capacity building, market and financial linkages, digital tools, and innovation incubation for FPOs across the state. It aims to transform FPOs from input retailers into vibrant rural enterprises that serve smallholders, promote regenerative agriculture, and build resilient value chains.

By creating this institution, Karnataka has set a national benchmark in agrarian reform—placing farmers at the center of enterprise, policy, and sustainability.

The FPOs as Instruments of Reform

The idea behind FPOs was simple yet powerful:

• Collectivize smallholders and workers to overcome scale disadvantages
• Enhance market access and bargaining power
• Promote value addition, branding, and enterprise development
• Create decentralized, farmer-led institutions that can anchor rural development

If implemented well, FPOs could play multiple roles:

• As economic engines for farmer income enhancement
• As social institutions for equity and inclusion (women, SC/ST, landless)
• As ecological stewards for sustainable and climate-resilient farming

Why FPOs Are Struggling: Systemic Challenges

Despite the noble intent, most FPOs remain trapped below the ₹1 crore turnover threshold. This is not because the model is flawed, but because the ecosystem around it is underdeveloped.

1. Top-Down Formation Without True Ownership

Most FPOs were formed to meet scheme targets, not farmer needs. Without grassroots participation or sustained handholding, they lack purpose and direction.

2. Weak Governance and Leadership

Board members often lack the training or business acumen needed to manage operations, ensure compliance, and make market-driven decisions.

3. Input Agency Trap

Many FPOs rely heavily on selling fertilizers, seeds, and pesticides—often under pressure from state schemes or private suppliers. This leads to short-term income but long-term stagnation, as they fail to build value chains or diversify services.

4. Lack of Market Orientation

Without reliable buyers or value addition, FPOs sell back into the same exploitative markets they were meant to escape—especially mandis and middlemen.

5. Limited Financial and Technological Infrastructure

Working capital, risk instruments, digital tools, and credit access remain weak. This limits scale, profitability, and ability to serve farmer members effectively.

Making FPOs Work for Smallholders and Farm Workers

Instead of abandoning the FPO model, we must course-correct and reform it—transforming FPOs from passive agents to active architects of India’s rural future.

1. Design for Farmers, Not for Forms

FPOs must be rooted in the needs and aspirations of their members. Priority should be given to:

• Inclusivity (women, youth, farm workers)
• Democratic governance and transparency
• Participatory planning and periodic training

2. Go Beyond Inputs—Become Rural Service Enterprises

FPOs should offer a full spectrum of services:

• Input retail + custom hiring + advisory
• Aggregation + processing + branding + marketing
• Digital payment systems, traceability, and real-time price intelligence
• Green economy services: composting, carbon farming, biodiversity credits

3. Invest in Market Linkages and Branding

FPOs should shift from being price takers to value makers by:

• Partnering with retail chains, exporters, processors, and digital platforms like ONDC, GeM, and eNAM
• Investing in storage, cold chains, and grading infrastructure
• Building FPO-level brands for local and global visibility

4. Enable Financial Inclusion and Risk Mitigation

Support from banks, NABARD, and fintechs must include:

• Working capital at affordable rates
• Insurance products and credit guarantees
• App-based accounting, dashboards, and compliance tools

5. Converge with National Missions and Green Growth

FPOs can serve as nodal institutions for:

• Natural farming and regenerative agriculture missions
• PM-FME, PM-KUSUM, and rural skilling programs
• Carbon and biodiversity markets, ESG funds, and circular economy projects

The Bigger Picture: FPOs as Pillars of Agrarian Renewal

When reimagined and revitalized, FPOs can play a central role in transforming India’s rural economy:

Function	Impact
Collective Production	Scale efficiency and reduced cost of inputs
Value Chain Integration	Capture more of the consumer rupee
Green Transition	Carbon neutrality, biodiversity, and climate resilience
Livelihood Diversification	Employment for youth and farm workers
Institutional Convergence	Link to health, nutrition, and social security schemes

Mindset Shift: From Projects to Enterprises

We must stop treating FPOs as one-off projects for subsidy disbursement and start treating them as farmer-owned, professionally-run rural enterprises.

An FPO is not a cooperative of the past—it is a 21st-century social business, one that can:

• Stabilize farmer incomes
• Revitalize degraded landscapes
• Empower marginalized communities
• Rebuild trust in agriculture as a dignified profession

Case Study: Grape Growers’ Collective Action– A Model of Informal Producers’ Organization (IPO)

From Solo Struggles to Collective Strength: How Informal Collaboration Reduced Input Costs for Grape Farmers

In the arid belts of North Karnataka, grape cultivation has been a long-standing livelihood for many smallholder farmers. Despite good yields and consistent efforts, the economic returns for these grape growers have been stagnating, causing distress and uncertainty.

During a field visit and interaction with a group of grape growers in the region, a harsh reality surfaced: while the cost of cultivation had increased nearly 300 times over the years, the selling price of grapes—whether fresh or dried—had remained the same or even declined due to market fluctuations.

Challenge Identified

On deeper inquiry, two primary cost drivers emerged:

1. High Cost of Agrochemicals
   Farmers were spending disproportionately on synthetic inputs—fertilizers, pesticides, fungicides, and plant growth regulators.
2. Irrigation-Related Expenses
   Drippers, pumps, and sprinklers added significantly to capital and recurring costs.

Additionally, input procurement practices were inefficient:

• Farmers purchased inputs individually from city retailers.
• Each farmer made separate trips, losing a day’s work and incurring transport costs.
• Due to lack of volume, they had zero bargaining power and ended up paying 10–15 times (and in some cases up to 30 times) more than wholesale prices.

Intervention

A simple yet transformative suggestion was made:
“Why not come together as a group and coordinate input procurement collectively?”

The farmers were guided to form an informal producers’ group—not a formal FPO, but a voluntary, trust-based working collective.

Key steps:

1. Identifying a Trusted Volunteer
   One literate and trustworthy farmer from the group was nominated as a coordinator.
2. Needs Assessment
   The coordinator collected input requirements from each member farmer (quantities, types, urgency, etc.).
3. Market Discovery and Vendor Engagement
   The group invited quotations from various suppliers and negotiated for bulk discounts.
4. Direct Village-Level Delivery
   The selected vendor agreed to deliver directly to the village, saving transport and time.

Outcomes

The results were immediate and significant:

• Farmers saved 25–30% on input costs through negotiated bulk discounts.
• Time savings were substantial—no more individual city trips, lost labor days, or dependency on transport.
• The process built trust, transparency, and collective learning among the farmers.
• Local employment was indirectly supported, as youth assisted in coordination and unloading activities.
• The model proved that trust-based informal producer networks can be economically effective and operationally agile.

Key Lessons

• Collective Farming Does Not Require Formality
  Even without registration or legal formation, small groups of farmers can act as de facto producer organizations and enjoy similar benefits.
• Local Leadership and Trust Are Critical
  Identifying a committed and transparent coordinator is the backbone of informal collectivization.
• Aggregation Unlocks Bargaining Power
  The shift from individual to group procurement transformed the farmer’s role from price taker to price negotiator.
• Replicability and Scalability
  This informal model can be applied across crops and regions, particularly in input-intensive systems like grapes, pomegranate, banana, and vegetables.

Implications for Policy and Agrarian Reform

This case reveals that small, decentralized producer groups, even when informal, can serve as the foundation for low-cost, farmer-led value chain transformation. It offers a bottom-up pathway to:

• Reduce cost of cultivation
• Improve farm economics
• Build rural social capital
• Prepare the ground for formal FPO evolution, if desired

Rather than pushing for formality first, agrarian reform efforts should recognize and support such informal producer innovations—through mentorship, access to market data, digital tools, and linkages with extension services.

This simple act of collectivizing input demand changed the equation for a community of grape farmers. It is a living model of cooperative action without formal structures—rooted in trust, guided by common interest, and leading toward true economic empowerment.

Such stories remind us: agrarian reform doesn’t always need policy first—it often begins with people.

FPOs Are Not the Problem-They Are the Platform

The issue is not that FPOs have failed, but that we have yet to fully equip them with the right policy frameworks, patient capital, institutional handholding, and farmer-first governance they need to flourish.

Rather than reducing FPOs to mere “input agents,” we must reposition them as the backbone of India’s rural and agrarian renewal, platforms that enable equitable growth, regenerative farming, dignified livelihoods, and market integration for smallholders and farm workers alike.

With the right reforms and ecosystem support, India has the potential to nurture 10,000 thriving, future-fit FPOs, each not only serving its members, but strengthening the economic, ecological, and social foundation of the nation.
