Delhi RWAs Pollution Control Committee (DRPCC) Formed to Tackle Capital’s Worsening Air Crisis

PRESS RELEASE

Delhi RWAs Pollution Control Committee (DRPCC) Formed to Tackle Capital’s Worsening Air Crisis

In a decisive move to confront Delhi’s escalating air pollution emergency, B. S. Vohra, an Environment Activist, & President of the East Delhi RWAs Joint Front, as well Convener of the RWA Bhagidari Network, has announced the formation of the Delhi RWAs Pollution Control Committee (DRPCC).

Vohra stated that the new committee has been established to address the crisis far more seriously and systematically than it has been so far.

“Despite the ongoing efforts of CAQM, CPCB, and DPCC, why does Delhi’s air quality continue to deteriorate year after year?” he asked. “Does this mean their actions are ineffective, or merely symbolic, lacking real impact?”

Highlighting the stark difference between past achievements and today’s grim reality, Vohra noted:

“In 2010, Delhi successfully hosted the Commonwealth Games. But in 2025, even the BCCI has opted to skip the Under-23 tournament due to pollution concerns.”

He added that the crisis has now reached a point where doctors are advising residents to relocate, and courts have shifted to virtual hearings to safeguard public health.

“Every year, thousands suffer from life-threatening medical conditions linked to pollution, yet authorities still fail to enforce strong, protective measures,” Vohra said.

Concluding with a powerful message, he posed a critical question that reflects the city’s growing frustration:

“Is there no one in the system who can be held accountable for this disaster?”

Vohra added that like-minded RWAs, domain experts, and citizen groups will be brought into the committee, strengthening a collective and sustained movement to save Delhi from the growing threat of air pollution.

How the Air Pollution levels keep worsening in the national capital city DELHI ?

The worsening air pollution in Delhi, despite the efforts of organizations like the Commission for Air Quality Management (CAQM), Central Pollution Control Board (CPCB), and Delhi Pollution Control Committee (DPCC), is a complex issue with multiple contributing factors. Here's a breakdown of some of the key reasons:

1. Vehicular Emissions

Number of Vehicles: The sheer volume of vehicles on the roads is a major contributor. Delhi has one of the highest numbers of vehicles in the country. Even with stricter emission norms and initiatives like the odd-even scheme, the number of vehicles continues to rise.

Diesel Trucks: Delhi serves as a major transportation hub, and a significant amount of pollution is caused by heavy diesel trucks passing through the city. Diesel engines emit large amounts of particulate matter (PM), nitrogen oxides (NOx), and other harmful gases.

2. Construction and Development

Construction Dust: With rapid urbanization, construction work is constantly happening in Delhi. Dust from construction sites is a significant contributor to air pollution, especially particulate matter (PM10 and PM2.5), which is harmful to health.

Infrastructure Projects: Large-scale infrastructure projects, like the Delhi Metro expansion, flyovers, and housing complexes, often lead to an increase in dust and emissions during their construction phases.

3. Burning of Crop Residue (Stubble Burning)

Neighboring States: A significant portion of Delhi's air pollution during the winter months (October-November) is driven by the burning of crop residues in neighboring states like Punjab, Haryana, and Uttar Pradesh. While efforts have been made to incentivize farmers to stop burning stubble, this practice continues due to economic and logistical constraints.

4. Industrial Emissions

Unregulated Industries: Despite efforts to regulate industrial pollution, many small and medium-sized industries around Delhi continue to operate with outdated, inefficient equipment, emitting large quantities of pollutants.

Power Plants and Boilers: Many coal-powered plants and boilers continue to contribute significantly to the pollution levels in and around the city.

5. Weather and Geography

Temperature Inversion: In winter, Delhi experiences temperature inversion, where a layer of warmer air traps cooler air near the surface. This phenomenon prevents pollutants from dispersing, causing them to accumulate and intensify air pollution.

Wind Patterns: The wind direction and speed during certain months can concentrate pollution in the city. Additionally, the local topography can trap pollutants, exacerbating the situation.

6. Firecrackers and Festivities

Diwali and Other Festivals: Every year, during festivals like Diwali, the bursting of firecrackers results in a sharp increase in air pollution, particularly in the form of particulate matter (PM2.5 and PM10). Despite public awareness campaigns, the practice continues to be widespread.

7. Waste Management Issues

Open Burning of Waste: The burning of waste, including plastic and other materials in landfills or on roadsides, is a common practice in Delhi. This adds to the toxic mix of pollutants in the air.

Garbage Piles: Inefficient waste management leads to the accumulation of garbage, which, when burnt, contributes to the city's poor air quality.

8. Insufficient Enforcement of Regulations

Weak Implementation: While there are many laws and regulations in place (e.g., restricting the use of stubble burning, encouraging cleaner fuels, or limiting construction dust), enforcement remains a challenge. There are instances of non-compliance by industries, construction sites, and even individuals, which contribute to the pollution.

Political and Bureaucratic Challenges: Air pollution is a politically sensitive issue, and different state and central authorities often have conflicting interests or insufficient coordination.

9. Climate Change and Long-term Changes

Increased Frequency of Extreme Events: Climate change is leading to more erratic weather patterns, making certain pollutants more concentrated during specific times of the year (e.g., longer periods of fog and stagnation in winter).

Long-Term Pollution Trends: Many of Delhi's pollution challenges are tied to years of industrialization, urbanization, and unchecked emissions. The long-term effects are difficult to reverse quickly.

10. Public Awareness and Behavioral Challenges

Public Behavior: Many individuals still don't fully understand the severity of the issue or how their actions (e.g., burning leaves, excessive use of private vehicles, improper waste disposal) contribute to pollution.

Lack of Alternative Options: Public transportation infrastructure, although improving, is still inadequate in many areas. People rely on private cars, contributing to traffic emissions. Moreover, affordable electric vehicle (EV) infrastructure is still in the developmental stage.

Efforts Being Made

Despite these challenges, several steps are being taken:

Graded Response Action Plan (GRAP): A framework to tackle air pollution with increasing severity depending on the pollution levels.

Air Quality Index (AQI) Monitoring: Real-time monitoring and reporting systems to provide timely information to the public.

Promotion of Electric Vehicles: Incentives to promote EVs and transition to cleaner energy sources.

Public Awareness Campaigns: Continuous campaigns to educate the public about the importance of reducing pollution.

Conclusion

The situation in Delhi is the result of a combination of socio-economic, environmental, and regulatory factors. While there have been improvements in certain areas (such as stricter vehicle emission standards and cleaner energy initiatives), the city is still grappling with pollution because of the complex and interconnected nature of the problem. The road to cleaner air will require stronger enforcement, systemic changes, better coordination among agencies, and more sustainable urban planning, all while balancing economic growth and the welfare of the population.

What aqi level in Delhi can cause permanent damage of Lungs?

What aqi level in Delhi can cause permanent damage of Lungs?

Here's a clear, safe, and science-based explanation:

AQI Levels and Risk of Permanent Lung Damage

The Air Quality Index (AQI) uses the same health-impact categories worldwide (including Delhi), though Delhi often reaches the highest bands. Permanent lung damage is not tied to a precise AQI number, but the risk increases sharply at very high and prolonged exposures.

Below is the standard interpretation:

AQI LevelCategoryHealth EffectsRisk of Long-Term / Permanent Damage
0–100Good/ModerateMinimalNone expected
101–200Unhealthy for Sensitive GroupsIrritation, reduced lung function (temporary)Long-term exposure can begin affecting children, elderly, and asthmatics
201–300UnhealthyBreathing difficulty for most peopleChronic exposure may cause measurable decline in lung function
301–400Very UnhealthySignificant respiratory distressHigh risk of long-term lung damage, especially with repeated or continuous exposure
401–500+Hazardous / SevereSerious health effects on everyoneProlonged exposure can lead to permanent lung damage, increased risk of COPD, and long-term impairment

So, what AQI level in Delhi can cause permanent lung damage?

➡️ Short-term spikes (even 500+) usually do not cause permanent damage alone, but
➡️ Repeated or long-term exposure to AQI above ~300–400 greatly increases the risk of lasting or permanent lung damage, especially from PM2.5.

Why?

PM2.5 particles (most responsible for Delhi pollution peaks) can:

  • lodge deep inside the alveoli,

  • cause chronic inflammation,

  • reduce lung growth in children,

  • accelerate lung aging,

  • increase lifetime risk of asthma, COPD, and heart disease.

Important note

This information is for general education, not medical diagnosis. If you have symptoms (persistent cough, breathlessness, wheezing), consulting a medical professional is recommended.

B S Vohra, Environment Activist, President, East Delhi RWAs Joint Front

Causes of Day Time severe Air Pollution in Delhi ?

Delhi’s hazardous daytime air pollution results from a combination of human activities and natural factors. The major causes include:


1. Vehicular Emissions

  • High population and rapid growth in vehicle ownership.

  • Traffic congestion leads to idling, increasing emissions.

  • Major pollutants: PM2.5, PM10, NOx, CO, and ozone precursors.


2. Industrial and Power Plant Emissions

  • Factories around Delhi-NCR emit particulate matter, sulfur dioxide (SO₂), and nitrogen oxides (NOx).

  • Brick kilns and small-scale industries often use dirty fuels like coal, wood, and furnace oil.


3. Construction and Road Dust

  • Continuous construction, demolition, and poor dust-control practices release large amounts of PM10.

  • Road dust resuspension due to traffic movement is one of the largest daytime contributors.


4. Biomass Burning Within the City

  • Burning of garbage, wood, and crop waste inside Delhi’s informal settlements contributes to toxic emissions.

  • Open waste burning is a major source of black carbon.


5. Stubble Burning (Seasonal but Severe)

  • Farmers in Punjab, Haryana, and Uttar Pradesh burn rice stubble.

  • Winds carry the smoke to Delhi, dramatically raising PM2.5 levels, especially in late October–November.


6. Atmospheric and Weather Conditions

  • Low wind speed during the day traps pollutants.

  • Temperature inversions can occur even in daytime winter months, preventing vertical dispersion.

  • Strong sunshine triggers photochemical reactions, increasing ground-level ozone.


7. Urban Heat Island Effect

  • Dense built-up areas trap heat, intensifying chemical reactions that form secondary pollutants like ozone and secondary PM2.5.


8. Diesel Generators

  • Commonly used during power cuts in markets, construction sites, and residential complexes.

  • Emit high levels of PM2.5, SO₂, and NOx.


9. Poor Fuel Quality & Waste Disposal Practices

  • Use of substandard fuels in transport and industry.

  • Improper waste disposal leads to open burning, especially during daytime when enforcement is weak.


Summary

Delhi’s hazardous daytime air pollution arises from a mix of local emissions (vehicles, dust, industries), regional sources (crop burning), and weather conditions that trap pollutants and enhance photochemical pollution.

Why is night AQI worse in Delhi?

How night aqi is higher in Delhi comparing day AQI, even though minimum vehicular emissions and parali fires can't impact only during night ?

There are clear scientific reasons why AQI in Delhi is often higher at night than during the day, even when traffic emissions are low and stubble-burning (“parali”) isn’t occurring at that exact time.

Here’s the explanation, step by step:


ЁЯМЖ 1. Night-time temperature inversion traps pollutants

This is the main reason.

  • After sunset, the ground cools quickly.

  • The air near the surface becomes colder than the air above it.

  • Cold air is heavier and cannot rise - this creates a temperature inversion layer.

  • Pollutants from day sources (vehicles, industry, dust, residual biomass smoke) get trapped near the ground, causing AQI to spike.

During the day:

  • Sunlight heats the ground → warm air rises → vertical mixing occurs.

  • Pollutants disperse upward → AQI appears better.

➡️ Even if emissions are low at night, the inability of pollutants to disperse makes the concentration appear higher.


ЁЯМм️ 2. Wind speed is lowest at night

  • Night-time winds tend to calm significantly in plains cities like Delhi.

  • With low or no wind, pollutants accumulate locally.

  • Even residual pollution from the daytime stays close to the surface.

Daytime winds + sunlight = better dispersion.


ЁЯПн 3. Continuous emissions (even at lower levels) still accumulate

Even though traffic decreases, these sources continue throughout the night:

  • Waste burning (often done at night)

  • Industrial emissions (not all factories shut down)

  • Construction dust

  • Domestic emissions (heating, cooking, generators)

  • Heavy trucks enter Delhi mostly at night (unless restricted)

Lower emissions + zero dispersion still leads to higher concentration.


ЁЯМл️ 4. Higher humidity at night forms secondary particles

At night Delhi’s humidity rises. Higher humidity promotes:

  • Formation of secondary particulate matter (especially PM2.5)

  • Hygroscopic growth of existing particles → they absorb moisture and get “bigger”

  • Fog + particulate interaction → smog

This increases PM2.5 readings even if pollution source is unchanged.


ЁЯФе 5. Parali (stubble burning) affects nights more due to wind patterns

Even though fires may occur in the day, their transport to Delhi often peaks at night:

  • Cooler night winds from Punjab/Haryana bring smoke into Delhi.

  • Unable to disperse due to inversion, the smoke accumulates.

So fires don’t have to happen “at night” to worsen night AQI.


ЁЯМГ 6. Chemical reactions differ between day & night

Daytime sunlight causes photochemical reactions that help break some pollutants (like NOx).
At night:

  • No sunlight → fewer reactions to degrade pollutants.

  • NO₂ builds up because it isn't photolyzed.

  • Ozone decreases at night, affecting secondary particle formation dynamics.

Overall effect → pollution stays in its most concentrated form.


✔️ In summary: Why is night AQI worse in Delhi?

Even with lower emissions, pollutants get trapped, accumulate, grow, and don’t disperse at night due to:

  • Temperature inversion

  • Low wind speed

  • Increased humidity

  • Residual emissions accumulating

  • Transport of pollution from outside Delhi

  • Suppressed chemical breakdown of pollutants

This phenomenon is common in polluted cities worldwide, but Delhi’s geography and winter conditions amplify it dramatically.

RWAs Advisory on Rising Air Pollution Levels in Delhi

 


RWAs Advisory on Rising Air Pollution Levels in Delhi

Dear Residents,

With the recent increase in air pollution levels across Delhi, the EDRWAJF urges all residents to take the following precautionary and preventive measures to safeguard their health and contribute to cleaner air in our community.


1. Health & Safety Measures

  • Limit outdoor exposure, especially during early mornings and late evenings when pollution levels are typically higher.

  • Use N95/N99 masks when stepping outdoors.

  • Keep windows and doors closed during peak pollution hours.

  • Use air purifiers, if available, especially for children, elderly individuals, and those with respiratory conditions.

  • Increase indoor ventilation during times when AQI is better (usually afternoon hours).


2. Protecting Vulnerable Groups

  • Ensure that children, senior citizens, pregnant women, and asthma patients avoid prolonged outdoor activities.

  • Keep essential medications (inhalers, nebulizers) readily accessible.


3. Reducing Local Pollution

Residents are requested to actively help reduce emissions in and around the colony:

  • Avoid burning leaves, garbage, or any waste.

  • Encourage carpooling, use of public transport, bicycles, and walking for short distances.

  • Turn off vehicle engines at red lights to prevent idling.

Suggestions on hike of the Property Circle Rates in Delhi

Department of Revenue, Government of NCT of Delhi, Delhi Secretariat, IP Estate, New Delhi – 110002

Subject: Request to Consider Livability and Ground Realities Before Hiking Circle Rates

Respected Sir/Madam,

I am writing to express concern over the proposed revision of circle rates in Delhi and to respectfully urge the government to ensure that ground realities and actual livability conditions are thoroughly considered before implementing any hike.

While revising circle rates to reflect market trends is understandable, it is equally important to assess whether the basic quality of life in each locality justifies such an increase. A rate hike without corresponding improvement in living conditions would be unfair to residents and prospective buyers.

Key factors that must be assessed before any revision include:

  • Air Quality Index (AQI) and local pollution levels

  • Road infrastructure and overall maintenance

  • Waterlogging during rains and poor drainage system

  • Presence of garbage mounds/landfills near residential areas

  • The state of the Yamuna River, especially in nearby localities as well availability of potable drinking water

  • Availability and quality of green spaces and public parks

  • Traffic congestion and average commute times

  • Lack of last-mile connectivity and accessible public transport

  • Waste disposal, sewerage, and sanitation infrastructure

  • Moreover the stamp duty of 7% is too high and must be looked into seriously as people are already paying huge taxes on their income & expenditure.

Without addressing these basic persistent issues, increasing circle rates may not only overburden citizens but also create a disconnect between property valuation and actual livability.

I urge the government to adopt a data-driven, area-specific approach and involve local stakeholders like Resident Welfare Associations (RWAs) in the decision-making process, via a public hearing. This will ensure that the revised rates are fair, transparent, and truly reflective of on-ground realities.

Thanking you,

B S Vohra

Objection Regarding FPPAC Notification – Request for CAG Audit and Public Hearing

15th September 2025

Secy.,
Delhi Electricity Regulatory Commission
New Delhi

Subject: Objection Regarding FPPAC Notification – Request for CAG Audit and Public Hearing

Dear Sir,

We are deeply concerned and disheartened by the recent notification issued by DERC proposing an automatic FPPAC monthly escalation of up to 10% in power tariffs for Delhi consumers. Such a move is both unprecedented and unjustified.

It is particularly alarming that DERC, an institution established to regulate power tariffs in the public interest, appears to be abdicating its core responsibility. 

Delhi’s consumers are already overburdened with excessive electricity charges — including high fixed charges, inflated sanctioned load costs, numerous surcharges, and an additional 16% Return on Equity (RoE) — all of which cumulatively place a significant financial strain on households.

Furthermore, the outstanding ₹27,200 crores categorized as "regulatory assets" — which continue to accrue heavy carrying costs and interest — raise serious questions about DERC’s oversight. The lack of transparency and accountability in the accumulation of these dues is a matter of grave concern.

Even the court sharply criticized DERC for its "regulatory failure" in allowing this massive amount to accumulate over time. The Supreme Court said it has "serious consequences on all stakeholders, and the ultimate burden is only on the consumer".

Therefore, In the absence of a comprehensive CAG audit and transparent public scrutiny, it is unacceptable from DERC and DISCOMs to continue burdening the people of Delhi — particularly in the context of the existing 49%/51% shareholding arrangement, to avoid the CAG Audit, demands greater regulatory vigilance, not less.

In light of the above, we strongly oppose this proposed automatic tariff escalation and place the following demands:

1. An immediate and comprehensive CAG audit of all Delhi DISCOMs.

2. A public hearing to be held, allowing direct engagement with stakeholders on the issues outlined above.

We urge DERC to act in the public interest and restore faith in the regulatory process. We await your prompt response on this matter.

Sincerely,

B S Vohra

Nearly 1,900 Industries Operating Without ETPs, Reveals MoEFCC Data


New Delhi: Around 1,900 industries are operating without effluent treatment plants (ETPs) across the country, data issued by the Union Ministry of Environment, Forest and Climate Change (MoEFCC) shows.

As per Indian laws, industries that generate wastewater, especially those with hazardous or high pollutant loads, are legally required to install ETPs, which are essential for industries to adhere to environmental regulations by processing wastewater before its release.

The Central Pollution Control Board (CPCB) mandates ETPs for all industries in the Red Category, which includes 17 highly polluting sectors like textiles, tanneries, pharmaceuticals, paper, chemicals, refineries, and distilleries.

In addition, many industries (moderately polluting) in the Orange Category, such as food processing, dyeing units, and metal finishing, also require ETPs based on effluent characteristics and local regulations.

According to the MoEFCC data, the total number of industries operating without ETPs across the country stands at 1,898. Out of these, Assam records the highest number, 795, followed by Gujarat, 366 and Haryana, 273.

There are a total of 69,854 industries which require ETP as identified by State Pollution Control Boards (SPCBs)/Pollution Control Committees (PCCs), out of which 67,956 industries have functional ETPs, as per the Ministry.

Action as deemed fit for the industries without ETP and non-complying with the standards has been taken by concerned SPCBs/PCCs as per the provisions of environmental laws, the data says.

Expressing concern over the matter, environmentalist BS Vohra on Tuesday told ETV Bharat that ETPs are vital for environmental conservation by treating industrial wastewater before it's released into nature.

"They help prevent water pollution by removing harmful chemicals and toxins, protecting rivers, lakes and groundwater. ETPs also safeguard aquatic life and public health by reducing contamination and disease risks. Additionally, they enable industries to reuse treated water, conserving freshwater resources. By ensuring compliance with environmental laws, ETPs support sustainable industrial practices and national initiatives like Namami Gange," Vohra added.

Environmentalist BS Vohra said Yamuna River is ecologically dead, largely due to the unchecked discharge of untreated industrial and domestic waste.

He said, overall, ETPs play a key role in reducing pollution, conserving water, and promoting a cleaner, healthier environment.

The environmental expert asserted that the Yamuna River in Delhi is ecologically dead, largely due to the unchecked discharge of untreated industrial and domestic waste. Despite decades of government programs like the Yamuna Action Plan and Namami Gange, pollution levels remain critical, with zero dissolved oxygen, making it uninhabitable for aquatic life.

"Illegal dumping by industries and poor enforcement by agencies like the Delhi Pollution Control Committee (DPCC) have exacerbated the crisis. Delays in establishing effluent and Sewage Treatment Plants (STPs) reflect administrative failure. Without strict regulation, real-time monitoring, and political will, the Yamuna will continue to deteriorate, posing serious environmental and public health risks," he said.

Vohra said, "To address the 1,898 industries lacking mandatory ETPs, the government must enforce strict compliance with environmental laws. This includes imposing fines, shutting down defaulters, and conducting regular inspections. Real-time monitoring and public disclosure of violators will enhance accountability. Financial incentives and support should be offered to smaller industries to set up ETPs or join Common Effluent Treatment Plants (CETPs)."

According to Vohra, strengthening the capacity and accountability of pollution control boards, along with involving third-party audits, is crucial. A combined approach of regulation, technology, and transparency is essential to protect waterbodies and public health, he added.

Green India Mission Leads To Increased Forest Cover, But Question Over Long-Term Impact Lingers


Green India Mission Leads To Increased Forest Cover, But Question Over Long-Term Impact Lingers

New Delhi: The Green India Mission (GIM) had a substantial impact on the overall enhancement of forest and tree cover in India, the Union Ministry of Environment, Forest and Climate Change (MoEFCC) said.

Being implemented by the MoEFCC since FY2015-16, GIM is among the eight missions specified in the National Action Plan on Climate Change to safeguard, rehabilitate, and improve forest cover while addressing climate change through plantation initiatives in both forest and non-forest areas in the selected landscapes through Joint Forest Management Committees (JFMCs).

Notably, an amount of Rs 909.82 crore has been released to 17 states and a union territory for the creation of plantation/eco-restoration over an area of 15,5130 hectares.

India's forest cover has increased from approximately 7,94,245 sq km to 8,27,357 sq km, representing a net increase of about 3,31,12 sq km, as per the data issued by the MoEFCC. These gains are attributable to various afforestation and restoration initiatives, including GIM carried out at both state and Central levels, it said.

In states like Madhya Pradesh, the implementation of GIM activities commenced in 2018-19. To date, Rs 123.26 crore have been released for taking up afforestation/eco-restoration activities in 32,831 hectares under different sub-missions of the GIM. Afforestation activities have been undertaken in Katni and Panna districts through various schemes and implementing agencies. Under the Working Plan Implementation scheme, afforestation is being carried out on forest land in Katni, North Panna, and South Panna Forest Divisions.

To ensure the survival rate and growth, monitoring of plantations under the GIM is carried out through a multi-layered approach involving both state and Central level mechanisms. States/union territories conduct annual physical verification of plantation sites to assess the survival rate of saplings and document reasons for any observed mortality.

The state forest department takes corrective interventions, including focused maintenance drives, to address site-specific challenges regarding survival rate. As part of their annual progress reports, states submit digital files and geo-tagged photographs of plantation sites to the MoEFCC for centralised verification and monitoring.

It may be mentioned that the MoEFCC has undertaken initiatives to raise awareness and encourage participation of local communities, such as the promotion of the "Ek Ped Maa Ke Naam" campaign to foster emotional and community connection to tree planting.

Environmental Expert's View

BS Vohra, an environmental expert, said GIM has the potential to improve air quality by increasing forest cover across the country. "The GIM has the potential to improve air quality by increasing forest cover, which helps absorb pollutants and produce oxygen. However, its actual impact on controlling air pollution has been limited. Implementation has been slow, with minimal focus on urban areas where pollution is most severe. Moreover, major pollution sources like vehicular emissions, industrial activity, and stubble burning remain unaddressed by the mission. As a result, despite GIM's efforts, air pollution levels continue to rise," Vohra told ETV Bharat.

Controlling air pollution requires broader, multi-sectoral strategies beyond afforestation alone to achieve meaningful and lasting improvement in air quality, said Vohra, who has been fighting environment-related issues for years in Delhi.

Referring to the GIM, he said, "The GIM aims to enhance forest cover, restore degraded ecosystems, and promote climate resilience. While its objectives are well-intentioned, its impact has been limited, especially in ecologically sensitive regions like Himachal Pradesh and Uttarakhand, where recurring disasters — landslides, floods, and cloudbursts — continue to wreak havoc."

Claiming that the implementation of the mission has faced significant delays, underfunding, and a lack of effective coordination between Central and state authorities, he said, "The actual afforestation and ecological restoration achieved so far fall short of targets, and monitoring mechanisms remain weak. Moreover, the mission has not adequately addressed issues like deforestation from infrastructure projects, unregulated urban expansion, and poor land-use planning, which are major contributors to the ongoing environmental crises in the Himalayan region."

"In both Himachal and Uttarakhand, fragile mountain ecosystems are under intense pressure due to unsustainable development. Roads, hydropower projects, and tourism infrastructure often ignore ecological considerations, leading to increased vulnerability to natural disasters. GIM's limited presence and poor integration with local communities and disaster management systems reduce its effectiveness," Vohra added.

To make a meaningful impact, Vohra said GIM needs better funding, community participation, real-time monitoring, and alignment with broader land and disaster management policies. "There must be a shift from symbolic tree-planting efforts to holistic ecological planning focused on long-term resilience, especially in vulnerable mountain states that are on the frontline of climate change."

For disaster-prone hilly regions of Himachal Pradesh and Uttarakhand, the GIM must evolve from a tree-planting scheme to a holistic ecological resilience strategy, Vohra said. "The mission can play a crucial role in disaster mitigation if it focuses on restoring native forests that stabilise slopes, prevent soil erosion and regulate water flow. Avoiding monoculture plantations and promoting deep-rooted native species is essential for long-term slope stability," he added.

He wants the GIM to be integrated with land-use planning and eco-sensitive zoning to restrict development in vulnerable areas. Bioengineering methods, such as planting grass and shrubs on slopes, can reduce landslide risks. Implementing watershed-based afforestation can control runoff and minimise flash floods, he said.

Vohra asserted that community participation is key as local knowledge and involvement in forest protection enhance the mission's effectiveness, adding green belts along roads, riverbanks, and other infrastructure should be promoted to act as natural barriers against disasters.

"The mission must be aligned with early warning systems and local disaster management plans. By focusing on ecosystem restoration, climate adaptation, and risk reduction, the GIM can significantly contribute to making hill regions safer and more resilient to natural disasters," he added.
