Sustainability

Delhi might soon be testing roads and buildings that can "digest" pollution. However, the real question here is not only about innovations but why cities must rethink sustainability urgently.

Delhi Government e this first of its kind initiative which partnership with Indian Institute of Technology Madras to study photocatalytic surfaces coated with titanium dioxide (TiO). These smart materials upon sunlight exposure, break down harmful pollutants like nitrogen dioxide (NO) and volatile organic compounds (VOCs) into less harmful substances such as water and nitrates. The six-month study will implement these coatings in the areas of the roads, pavements, and building surfaces that may transform daily infrastructure to be the passive air purifiers.

Science backs it up. Continuously neutralising the pollutants without any additional energy input, photocatalysis allows for the surfaces to be low in maintenance and easily upgradeable. As a city which recorded no "good" air quality days in 2025 such tools could be a long-term addition to the policy measures which have been failing to produce results.

On the other hand this new technology does not help us to answer the more profound question: Are we merely trying to fix the pollution after it has been created when really we should be preventing it in the first place?

TiO coatings work - but they're not a fix. They clean up after the fact, like wiping blood off a wound. Delhi's air is poisoned by cars. Building dust, factories, and how energy is used - no real shift means these materials stay just that: temporary solutions.

Sustainability isn't about green slogans anymore. It's about cutting out polluting systems entirely. Public transit over private cars, efficient buildings, strict construction rules - these changes matter more than any new filter or paint. It seems hard to ignore how much we depend on old habits.

Then there's IIT Madras' work, quiet but real. These systems don't ask for change in behavior. And they just absorb pollution quietly. In cities like Delhi where emissions are high, such passive filters could cut down on exposure a lot.

The future doesn't rely only on tech or policy. It needs both - prevention and cleanup together. If Delhi pairs smog-reducing layers with real urban shifts, it might show how cities can respond differently to environmental threats, something arguably worth trying now. A passive system alone won't solve the problem, just a change in how people live and build does. that is what matters most soon.

Because ultimately, the goal is not just to build roads that clean the air—but to build cities that do not choke it in the first place.

India's academic institutions are the new targets of the fuel shortage. The Indian Agricultural Research Institute, also called Pusa Institute, has requested almost 600 students to vacate the hostels on the campus. They will be moving to online teaching from April 6, 2026. The move has been made as the situation between US and Iran continues to get tense. It's not just about running labs or offices - it's about how fragile campus food services are when fuel stops flowing. Energy access remains a core issue for institutions that rely on centralized messes.

ICAR runs the institute and funds its operations. Undergraduate, first-year Master's, and PhD students are all being asked to return home. About 1,800 students live on campus. Around 600 of them are being moved out now. This shift isn't temporary anymore, it's a direct result of energy instability. Students can't go to meals or dorms without fuel deliveries. Their daily routines depend on uninterrupted supply chains.

Hostel messes operate off one key input: fuel. That creates risk during international conflicts or supply chain breaks. The institute says current energy shortages are disrupting food services. Without backup systems or alternative power sources, campuses stay exposed to outside shocks. Long-term planning must include energy diversification for stability.

And the campus isn't completely silent, second-year and senior grad students keep working on research, still doing labs and offline classes. That shows a push to maintain advanced work. But displaced students' hands-on training will wait until they come backit makes you wonder if this kind of delay could stretch long-term. Resource planning feels shaky right now.

What we're seeing isn't just a short-term issue. It hits deep into how institutions function. Public schools like IARI are tiny versions of bigger systems. When one breaks down, the whole system shakes. The crisis calls for energy-resilient designs - like local cooking setups, solar power integration, and varied supply paths.

This shift forces sustainability into daily operations. With energy markets unstable, campuses can't rely on outside fuel for labs or food prep. How they run now depends on reducing outside inputs - no more blind dependence on distant sources.

For now, students return home and learning continues online. But the larger question remains: can India’s premier institutions transition from crisis response to sustainable preparedness?

Every morning begins with invisible labor.

A spoonful of palm oil in processed food, a cup of coffee, a bite of banana, a piece of chocolate made from cocoa—these are not just commodities. They are the outcome of a global system built on land, climate, and above all, labor. And today, that labor is quietly disappearing.

For over a century, tropical plantation economies have operated on a model inherited from colonial rule—export-driven, labor-intensive, and dependent on a workforce that was abundant, inexpensive, and largely invisible. Independence redrew political borders, but not the architecture of production. The fields remained the same. So did the expectations from those who worked for them.

But something has shifted.

Across Southeast Asia, West Africa, and Latin America, plantations are no longer struggling with yield alone—they are struggling with relevance. The question is no longer how to grow more, but who will choose to grow at all.

An Economy Built on Extraction, Now Facing Exhaustion

The numbers tell a stark story. In Malaysia, migrant workers now account for nearly 70–80% of the palm oil workforce, a dependency so deep that when borders closed during the pandemic, production faltered almost immediately. In Indonesia, where foreign labor is less dominant, the system relies heavily on internal migration—yet even here, younger generations are stepping away.

Globally, smallholders contribute around 40% of Indonesia’s palm oil output, yet remain locked out of certification systems meant to define “sustainability,” unable to bear the costs of compliance. What emerges is a paradox: those closest to the land are the furthest from the benefits of reform.

The plantation, once a site of economic certainty, is now a place young people actively avoid—seen as physically punishing, socially undervalued, and economically limiting.

The Human Cost Beneath Green Labels

During the last twenty years or so, sustainability has been the chief discourse of global agriculture. Certification schemes such as the Roundtable on Sustainable Palm Oil (RSPO) have changed the way supply chains are inspected and promoted. We can measure, track and even put a price on changes in forest cover, carbon footprints and product traceability.

However labor which is at the very core of these systems, is still mostly ignored.

In fact, women are the ones standing at the most vulnerable points of this economy. They do informal jobs mostly, get very little pay and are not given social security benefits, at the same time, they also do the unpaid household work which is most of the time not recognized. On the other hand, men still have to do the physically heavy work, often in conditions that have hardly changed for decades.

This does not only lead to inequality but also to exhaustion on a large scale - systemic, across generations, fatigue.

A Crisis of Aspiration

At its core, this is not simply a labor shortage. It is a crisis of aspiration. Rural youth are not rejecting agriculture out of indifference, but out of awareness. They are choosing mobility over stagnation, dignity over endurance. In doing so, they are exposing the limits of a system that has failed to evolve with them.

As the Food and Agriculture Organization has repeatedly emphasized, rural employment is no longer a peripheral concern—it is central to the sustainability of agricultural systems. Without workers, there is no harvest. Without dignity, there are no workers.

Beyond Yield: Rethinking What Sustainability Means

If the first face of sustainability was environmental, then the next one has to be human. It is about bringing plantations back as communities where human beings can live, grow and work rather than as places where only natural resources are extracted. It is also about introducing the use of mechanisms that keep the workers physically healthy as well as timely and fair payment of wages, comprehensive training that empower rather than keep the workers in a helpless cycle situation, etc.

Programs, such as the TALENT, supported by international development agencies, change this by concentrating effort on skills, pathways, and the appeal of farming over time. However, such efforts are scattered and tardy to overcome the magnitude of the challenge.

The Question That Remains

The question that remains is whether it is common to describe the future of tropical agriculture in terms of climate resilience/yield optimization or supply chain transparency. These are very important. Nonetheless, they alone cannot contribute to the development of tropical agriculture.

In fact, every indicator carries a hidden question that is rarely posed, and even less frequently answered: who will remain? Just as a detailed and good map requires a lot of features besides the economic aspects in order to identify social and political aspects of the 'who will stay' question, if we do not understand who will stay, the future of tropical plantations will be a mystery. It is not land production but the shrinking number of people who will want to belong to it that is being questioned.

In a significant step toward sustainable energy transition, scientists at CSIR-National Chemical Laboratory have developed an indigenous technology to produce Dimethyl Ether (DME)—a clean-burning synthetic fuel that could reduce India’s dependence on imported LPG and reshape the country’s household energy landscape.

At a time when India imports over 80% of its fossil fuel needs, innovations like DME are emerging as critical to both energy security and environmental sustainability. The development aligns closely with the country’s broader push for self-reliance under the Atmanirbhar Bharat mission.

A Cleaner Alternative for Everyday Use

Dimethyl Ether is on the rise as a globally recognized low-emission fuel, which when burnt, contribute far less levels of soot, nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter than traditional fuels. Even though it is much cleaner, it delivers heat efficiency similar to LPG, that makes it an excellent substitute for cooking and heating.

Also, using DME does not mean we have to completely change the existing infrastructure. As per the Bureau of Indian Standards, blending up to 20% of DME with LPG is the permissible limit. Further, A blend of even 8% DME with LPG is thought to be doable without any changes to cylinders, regulators, or burners, thus the transition is very easy for households.

Economic Gains Allow Environmental Benefits As Well

India is caught on the hook for over 21,000 crore every year due to the import of LPG. Scientists predict that replacement of a mere 8% of LPG with DME may yield approximately 100 billion annual savings.

Such savings can really make a difference when it comes to a welfare scheme like PMUY (Pradhan Mantri Ujjwala Yojana) which is providing LPG connections to more than 100 million families. The transition to DME not only will significantly ease subsidy burden but also guarantee access to clean fuel to the poor.

Technology Prepared for Mass ProductionWhat makes it different is a fairly inexpensive catalytic procedure that turns methanol into DME at a fairly low pressure. So, it can be directly packed in LPG cylinders. This system combines the chemistry of catalysts with the engineering of reactors efficiently to produce, and is recognized to be the creation of scientist Thirumalaiswamy Raja. The technology has already been put to the test at a pilot level handling 250 kg per day with the industrial demonstration plant of 2. 5 tonnes per day production capacity is being planned.

The project could scale up to commercial levels of 50100 tonnes per day, which would be a huge step toward the mainstream, if it gets the green light. More to Real World Usability, They Also Built a Flexible Burner which Can Run on LPG, DME or Any Combination: They Took It to National Labs for Efficiency Testing. Green Fuel with Multiple Uses Besides CookingInitially, its main purpose will be to cook food at home; however, the use of DME opens up a whole new array of possibilities. Besides that, it might serve as a fuel for vehicles, a propellant for aerosol as a substitute for CFCs - harmful ones, and a chemical intermediate in industrial manufacturing - therefore a component capable of making a cleaner energy environment.

Indias development of DME is a logical extension of quite a large part its sustainability strategy: from a dependence on importing fossil fuels to domestic production of clean energy alternatives.

As oil PSUs partner with bioenergy companies and implement more such projects, the technology can become an important tool in curbing emissions and enhancing energy independence.

Indeed, if DME is to be considered a success, the primary metric will not be cost savings, but the degree to which it facilitates the countrys transition to a low-carbon, resilient, and self-reliant energy future.

In a significant development for India’s growing startup ecosystem, PW School of Startups has received official incubator accreditation under the StartInUP programme. The move positions the initiative as a government-recognised startup incubator in Uttar Pradesh, strengthening support for early-stage founders.

Physic Wallah, while announcing the development, stated that the PUCS accreditation allows the commencement of shop of start ups (PW SOS) to be recognized as a state backed incubator, which means the incubator will be exposed to the policy support, funding access, and structured mentorship for entrepreneurs.

Being a certified incubator, PW SOS is set to offer their start-ups complete support services, including mentorship, business coaching, and product development assistance. Also, it will provide startups an opportunity to work in co-working spaces. The startup founders will get an opportunity to get seed capital and connect with venture capital networks, which can help them rapidly turn their innovative ideas into a successful business.

For PW SOS, this accreditation is a significant achievement as it plans to develop a multi-city incubation model starting with Uttar Pradesh. This move will not only help nurture startups at metro cities but also strengthen regional entrepreneurship.

Besides providing operational assistance, the incubator will also guide startups in figuring out the government-backed schemes and policies, especially in the area of grants and financial incentives that are offered within state regulations. This will entail providing information on eligibility criteria, application steps, and meeting the requirements for compliance.

The StartInUP program initiated by the Uttar Pradesh government is a platform for promoting innovation, employment creation, and startup growth through the construction of a strong ecosystem consisting of incubators, investors, and policy makers all over the state.

By being recognized in this way, PW School of Startups become a part of an increasing number of government-approved incubators that are devoting to turning ideas into realities. Those who follow the industry say that the partnerships between edtech platforms and public policy frameworks have the potential to democratize entrepreneurship by providing resources to aspiring founders from Tier-2 and Tier-3 cities.

It highlights a larger movement of education platforms turning into centres of innovation, which are not only focused on education but also on the creation of enterprises in the Indian startup scene that is expanding very swiftly.

Oceanic and atmospheric signals are starting to line up and indicate that El Nio conditions will strengthen by June, according to the latest European Centre for Medium-Range Weather Forecasts predictions. The pattern of the ocean and atmosphere development that has been seen so far is one of the "classic" El Nio features with sea surface warming in and near the central and eastern parts of the Pacific Ocean and the changes in the atmospheric circulation that go along with it.

Normally, the trade winds push the warm ocean waters towards Southeast Asia which causes the cold waters to rise near South America. When El Nio occurs, these winds are weakened resulting in the warm water spreading eastward. This causes a disruption of the global weather systems with the Pacific region experiencing more rainfall and parts of Asia such as India having hotter and drier conditions.

In India, these types of events are typically associated with a weaker southwest monsoon and more heatwaves. The monsoon relies on the difference in temperature between the land and the ocean to bring moisture-laden winds. Unfortunately, El Nio can diminish this gradient thereby reducing the rainfall and increasing the risk of drought in several areas.

Experts of climate warn that if a powerful el nino arises, India could be hit by two extremes at once - very high temperatures in the northern and central regions and below-normal amounts of rain during the monsoon. This would impact farming, the availability of water and people's health.

The record breaking warm global temperatures and drastic changes in the climate which occurred with the El Nio events (199798, 201516) made scientists very concerned. They point out that a similar El Nio event coupled with the present global warming scenario might result in intensity of climate extremes becoming more violent.

The pattern of the development of the event in the world at large is capable of decreasing the number of hurricanes in the Atlantic but at the same time raising the number of cyclones in the western Pacific. Even though how strong the event will be is not yet clear, the signs are there that a big climate occasion is taking place and so is likely to impact India and some other parts of the world in the following months.
