In an era when deforestation and climate change threaten ecosystems worldwide, one man from Gujarat—a state on the west coast of India—is rewriting the narrative of environmental restoration.

Dr. Radhakrishnan Nair, fondly known as Nairji, has created 122 forests across India, transforming barren landscapes into thriving ecosystems. His most remarkable achievement, Smritivan (a memorial forest) in Gujarat—recognized as the world’s largest Miyawaki forest—stands as a testament to his vision. Spanning 470 acres and home to over 500,000 trees, this forest is not just a memorial but a beacon of ecological hope. Nair’s work demonstrates how one individual’s determination can combat global warming, restore biodiversity, and inspire communities to embrace a greener future.

From entrepreneur to green crusader

Born in Kasaragod, Kerala, R.K. Nair’s path to becoming India’s “Green Hero” was anything but conventional. After failing his 12th-grade exams, he took on a series of odd jobs, eventually rising to become a successful entrepreneur in the garment industry. But a pivotal moment came in 2011, in Umargam, Gujarat, when he witnessed the felling of 179 ancient trees for road construction. The cries of displaced birds and the destruction of their habitat struck a deep chord.

“I felt the birds were speaking to me,” Nair recalls. “That day, I vowed to create forests where no one would harm them.”

This epiphany led to the founding of Forest Creators with his friend Deepan Jain in 2014. Using corporate social responsibility (CSR) funds, Nair began planting trees—starting with 1,500 saplings on a single acre. Today, he has planted over 3.2 million trees across 12 Indian states—from Gujarat to Chhattisgarh, Rajasthan to Uttar Pradesh. His approach blends the Japanese Miyawaki method, known for rapid and dense forest growth, with a localized adaptation he calls Bharatavanam, tailored to India’s diverse ecosystems.

Smritivan: A green miracle in the Desert

Nair’s crowning achievement is Smritivan, a sprawling forest in Bhuj, Gujarat, established in memory of the 13,805 victims of the 2001 Gujarat earthquake. Originally conceived in 2004 but long stalled, the project gained new life when Nair took charge. Despite the 470-acre terrain being arid and hilly, he began planting in July 2021. “By August 2022, when Prime Minister Narendra Modi inaugurated the memorial, the forest had reached an astonishing 16 feet in height, with 223,555 saplings planted in the first phase alone. Today, Smritivan houses over 525,000 trees, with plans to add 40,000 more,” Nair says, in an interview with EdPublica.

A report from the Gujarat Ecology Commission, accessed by EdPublica, highlights Smritivan’s ecological transformation. Now home to 117 tree species, the forest supports 79 bird species, 28 types of butterflies, 21 reptiles, nine mammals, and two species of fish. The dense canopy and mulched soil prevent erosion, retain moisture, and enrich the land with organic matter. “With an 86% tree survival rate, species like neem and casuarina are flourishing,” according to the report published in 2023.

The forest has also led to localized temperature reductions, while its 50 check dams help replenish groundwater. A one-megawatt solar plant further bolsters its sustainability, making Smriti Van a global model of eco-restoration.

Industrialist Anand Mahindra recently shared a viral post on X, praising Nair for building the world’s largest Miyawaki forest.

Ecological impact: Restoring balance

Nair’s forests are more than green patches—they are ecological engines. “In Chhattisgarh, the coastal forest of 103,000 trees raised groundwater levels dramatically—from 160 feet to just 12 feet—reviving wells and sustaining communities,” Nair claims. Across India, his forests have restored biodiversity, attracted wildlife, and helped rebuild natural food chains.

The Gujarat Ecology Commission underscores Smriti Van’s role in carbon sequestration, a vital tool against climate change. Experts recommend ongoing assessments to quantify its carbon storage potential, which could significantly offset emissions.

Nair’s method ensures long-term ecological success. He doesn’t merely plant trees—he nurtures ecosystems. By selecting native species suited to local conditions, his forests are resilient and sustainable. They grow 10 times faster than natural forests, mimicking 150-year-old ecosystems in just 10–15 years. Dense planting (3–4 saplings per square meter) encourages vertical growth, mimicking natural competition for sunlight.

A Vision for the future

Nair’s ambition is bold: planting one billion trees by 2030. Backed by governments, corporations, and citizens, Forest Creators is scaling up to meet this audacious goal. His work has earned international acclaim, including an invitation to represent India at a NASA conference and a UNESCO Prix Versailles award for Smritivan.

Yet, Nair remains grounded—dressed in his signature white mundu, shirt, and cap—a nod to his Malayali roots and the spirit of India’s farmers.

Beyond ecology, Nair’s forests are also community spaces. Smriti Van has become a popular destination for its tranquil trails and vibrant festivals, with 94% of surveyed visitors citing its fresh air and peacefulness. Future plans include guided tours and educational programs to engage youth in environmental stewardship.

A Global inspiration

R.K. Nair’s story is a clarion call for individual action in the face of global crises. His 122 forests—especially the monumental Smritivan—showcase what one person’s vision and persistence can achieve. By restoring biodiversity, cooling urban climates, and sequestering carbon, Nair’s work supports global efforts to fight climate change. As he marches toward his billion-tree goal, he reminds us that a single seed, planted with purpose, can grow into a forest of change.

Vantara: Inside a Billionaire-Backed Bid to Build a Global Wildlife University

The launch comes at a time when conservation challenges are becoming increasingly complex.

A new private university focused on wildlife conservation and veterinary sciences is being positioned as an ambitious attempt to reshape how the world trains the next generation of conservation professionals—backed by one of Asia’s most influential business families.

The institution, Vantara University, has been launched in western India by a wildlife initiative founded by Anant Ambani, part of the Reliance group. Framed as an integrated academic ecosystem, the project reflects a growing trend where private capital is stepping into areas traditionally led by public institutions and global nonprofits.

Vantara officially describes the university as the “world’s first integrated global university” dedicated to wildlife conservation and veterinary sciences. While the scale and integration may be distinctive, similar disciplines are already taught across universities worldwide, often through specialised schools, research centres, and veterinary colleges.

The claim, therefore, rests less on the existence of such education and more on the attempt to consolidate it within a single, purpose-built institutional framework.

A Shift Toward Education-Led Conservation

The launch comes at a time when conservation challenges are becoming increasingly complex. Climate change, habitat fragmentation, and the spread of zoonotic diseases are reshaping ecosystems and exposing the limits of traditional conservation models.

There is a growing recognition that protecting biodiversity will require not just field interventions, but a systemic expansion of expertise—from wildlife veterinarians and epidemiologists to policy specialists and conservation planners.

Vantara University aims to respond to this gap by bringing together disciplines such as wildlife medicine, genetics, behavioural sciences, epidemiology, and conservation policy under one academic structure.

Blending Science, Scale, and Philosophy

The university’s vision combines scientific training with a philosophical framing rooted in compassion and stewardship. Its design draws inspiration from historical centres of learning, while positioning itself as a modern, purpose-led institution.

“The future of conservation will depend on how we prepare minds and institutions to serve life with compassion, knowledge, and skill,” Anant Ambani said in a statement.

“Vantara University is shaped by a deeply personal journey of witnessing animals in distress and recognising the need for greater capability in their care… the university seeks to nurture a new generation committed to protecting every life.”

Global Ambitions, Local Foundations

Although based in India, the project is clearly aimed at a global audience.

The university plans to offer undergraduate, postgraduate, and specialised programmes, supported by research infrastructure and international collaborations. It also emphasises action-oriented learning, linking academic work with real-world conservation practices.

This approach reflects a broader shift in higher education, where institutions are increasingly expected to produce not just knowledge, but deployable expertise.

The Rise of Private Influence in Conservation

The initiative also highlights a larger structural shift: the growing role of private capital in shaping conservation agendas.

Historically, conservation has been driven by governments, multilateral agencies, and non-profit organisations. However, large-scale funding gaps and the urgency of environmental crises are opening the door for philanthropic and corporate actors to play a more prominent role.

This raises both opportunities and questions.

Private initiatives can accelerate innovation and investment, but they also bring concerns around governance, accountability, and long-term alignment with public interest.

Questions of Access and Impact

As with many specialised institutions, accessibility will be a critical test.

While the university has announced scholarships aimed at supporting students from diverse backgrounds, the broader question remains: can such models scale inclusively, particularly for communities most directly affected by environmental change?

The effectiveness of the initiative will also depend on its ability to influence policy, contribute to global research, and produce professionals equipped to address complex ecological challenges.

A Changing Conservation Landscape

The launch of Vantara University signals a deeper transition in how conservation is being imagined.

Increasingly, the field is moving beyond isolated interventions toward integrated systems that connect science, education, and practice. In this context, universities are not just centres of learning—they are becoming critical infrastructure in the fight to preserve biodiversity.

Whether this particular model succeeds will depend on execution, collaboration, and its ability to move beyond vision into measurable impact.

But its emergence underscores a central reality:

The future of conservation may depend as much on classrooms and laboratories as it does on forests and protected areas.

A new global commission led by The Lancet has been launched to examine the growing health and justice impacts of sea-level rise, as climate change accelerates risks for millions living in coastal and low-lying regions.

The Lancet Commission on Sea-Level Rise, Health and Justice, announced on April 8, brings together 26 international experts to assess how rising seas are reshaping public health, livelihoods, and global equity.

A Growing Crisis Beyond Climate

Sea-level rise, driven by anthropogenic climate change, is already contributing to displacement, food and water insecurity, and changing patterns of infectious diseases. The Commission marks the first major effort to analyse these intersecting risks through a health-focused lens.

“This commission comes at exactly the right time… sea-level rise is no longer a distant threat. It is already disrupting lives, health and wellbeing, especially for the most vulnerable,” said Christiana Figueres, Co-Chair of the Commission and a former UN climate chief.

Experts warn that the impacts extend far beyond environmental damage, affecting the social and economic fabric of vulnerable communities.

“Rising seas don’t just threaten coastlines, they threaten lives, livelihoods, and basic fairness. This is not only a climate problem. It is a health crisis, a justice crisis, and an urgent call for collective action,” said Jemilah Mahmood, Commissioner, Lancet Commission, and Executive Director of the Sunway Centre for Planetary Health, Malaysia.

An Urgent Global Health Challenge

The Commission is supported by the WHO Asia-Pacific Centre for Environment and Health and aims to generate evidence-based policy recommendations to strengthen adaptation, resilience, and equitable responses.

Dr Sandro Demaio, Director of WHO ACE, emphasised the immediacy of the crisis.

“Sea-level rise is no longer a distant threat — it is a public health emergency unfolding now. Through this WHO supported global Commission, we are clear: inaction is not neutral, it is a choice that puts lives and justice at risk.”

Human Impacts at the Core

The Commission also highlights the disproportionate burden on vulnerable populations, particularly in coastal and low-income regions.

“Rising sea levels are more than an environmental issue; they quietly contaminate water, displace communities, and increase health risks for those least able to cope. Every centimetre of sea level rise is not just a measure of water, but a measure of injustice,” said Kathryn Bowen, Co-Chair of the Commission.

A Defining Policy Moment

With projections suggesting that hundreds of millions of people could be displaced by the end of the century, the Commission aims to inform global policy and strengthen international cooperation.

“Sea-level rise is not just an environmental issue — it is a test of our commitment to people, equity, and future generations,” said Jiho Cha, Member of Parliament, Republic of Korea and Co-Chair of the Commission.

The Commission will contribute to global policy discussions, including international climate platforms, and aims to place human and planetary health at the centre of climate action.

Why Campuses Need a Happiness Officer Now

Rising student stress and depression highlight the need for a happiness officer on campus to promote wellbeing and prevent mental health crises.

Student Stress Is Rising. Campuses Need a Happiness Officer

As student stress and mental health challenges rise, educational institutions must move beyond symbolic gestures and invest in structured wellbeing systems—starting with a dedicated happiness officer on campus.

The rising need for happiness

20 March was celebrated as the International Day of Happiness.

The idea of creating an International Day of Happiness is a great one; it deserves to be taken seriously. However, there is a need to do much more than celebrate happiness for just one day a year. This becomes crucial when one considers the rising problem of stress, depression and suicides among young people around the world, including in India.

The challenges of stress, depression and suicides among students

The education system places significant pressure on students, yet they are rarely taught how they, their parents, teachers or the system itself can help them cope with this pressure—or how to view their efforts in the right perspective.

Because of a lack of awareness, education and capability, stress has become a major issue in students’ lives, often leading to depression and, in some cases, suicides. These challenges have far-reaching negative impacts across different aspects of life, as supported by multiple research studies.

A happiness officer on campus

Since happiness is an essential ingredient for a fulfilling life—and also acts as a preventive factor in dealing with stress—it is important to give it greater importance in educational institutions.

Institutions already place heavy demands on faculty and staff, who may not have the time to actively focus on student wellbeing. In this context, employing a dedicated happiness officer to address health and wellbeing on campus could be a significant step forward.

The happiness officer’s primary responsibility should be to raise awareness about happiness, as well as the dangers of stress and depression, among students, faculty, staff and others on campus. This awareness must be continuous rather than occasional.

The second responsibility should be to organise regular programmes in engaging ways, covering themes such as what happiness is, why it matters, and how it can be cultivated, alongside practical approaches to understanding, avoiding and managing stress.

The third responsibility should be to track individuals who may be experiencing stress or depression and ensure they receive timely support. Additional responsibilities can be developed depending on the needs and context of each institution.

Avoiding the trap of tokenism

However, awareness initiatives and programmes must be implemented with sincerity and intent. The happiness officer must work in both letter and spirit to create meaningful impact, rather than simply fulfilling formal requirements.

This role should not fall into the common institutional trap where ticking boxes becomes more important than creating real change on the ground.
