Dear Maj Manivannan:

Subject: Urgent Attention Required for Museum & National Military Memorial Completion and Inauguration

On behalf of all stakeholders eagerly awaiting the completion of the National Military Memorial, I extend a warm welcome as you assume charge as the BDA Commissioner. We are writing to you with a deep sense of urgency regarding the persistent delays plaguing the inauguration of this significant national tribute.

As you are aware, the foundation stone for the National Military Memorial was laid in 2009, making it nearly 17 years since its inception. While we appreciate that we are closer to the inauguration than ever before, several critical issues remain unaddressed, hindering its official opening and proper upkeep. An annexure detailing some of these historic issues has been separately shared.

One of the most pressing concerns is the Military Museum, a cornerstone of the Memorial. Located underground, it has been largely unattended and uncared for over the past decade. This neglect over 12 years, has led to significant issues, including water leakage and other damages that require immediate attention. We understand from various sources including the architects, that a modest budget of approximately >₹25 lakhs is required to bring it to a functional state. So the BDA, who is in charge  of NMM as well as the NMM Trust and the GoK needs to budget this and set this aside so work commences

Beyond the critical focus of the  museum, several other vital aspects demand your focus:

• Main path Lighting: The most critical issue impacting safety and accessibility is the complete absence of lighting within the Memorial. This creates a dangerous environment, increasing the risk of accidents, injuries, or even serious incidents, as has unfortunately occurred in other dimly lit public spaces. Adequate lighting is paramount for public safety and to ensure the Memorial is accessible to all at appropriate times

• Signage and Displays: The current signage and display elements require significant upgrades and repairs to ensure clear navigation and a fitting presentation of the Memorial's historical significance.

• Repairs and Access: Steps, pathways, and other access points throughout the Memorial grounds are in disrepair and pose safety concerns, particularly for visitors with disabilities..

• Park Maintenance: While perhaps less critical for immediate inauguration, the ongoing maintenance of the Memorial park requires dedicated budgetary allocation and immediate attention to ensure its setting  and sanctity are preserved.

  
  

Given your distinguished background as a Major, we are confident that you understand the profound significance of this Memorial and the honour it represents. We earnestly seek your support to ensure these pending items are addressed with the utmost urgency. Completing this precious tribute without further delay is not just a matter of infrastructure, but of national pride and respect for our armed forces.

Thank you so much for your time and attention to this critical matter. We truly appreciate the effort and focus you can bring to expedite the completion and inauguration of the National Military Memorial.

Sincerely,

Priya Chetty-Rajagopal

Proposed Felling of 626 trees- Devanahalli Open Jail Ground Jail

The DCF Rural , 

Bangalore, Karnataka

Dear Sir/Madam,

It is with a profound sense of dismay that I address the proposed felling of 626 heritage trees at Survey No. 100, within the Devanahalli open ground jail area, Bangalore Rural District. This is not merely about trees; it's about the continued erosion of Bengaluru's green cover and the irreversible damage to our city's delicate ecological balance.

The notion that an "open jail" necessitates such extensive tree clearance seems fundamentally flawed. One would logically assume that an open correctional facility would integrate with, rather than decimate, its natural surroundings. Perhaps a perimeter wall, with minimal tree removal for essential security, would suffice, allowing these vital natural assets to remain. This clearance is reportedly for a new central jail, accommodating only 600 inmates, along with associated non-residential buildings and road infrastructure. While I acknowledge the need for infrastructural progress, it cannot come at the expense of our environmental heritage.

Bengaluru, once celebrated as the Garden City, is increasingly suffering from the "greying of Bangalore." This relentless concretization, often driven by a transactional approach to trees by our city government, treats our invaluable green infrastructure as expendable. The systemic disregard for mature trees, which offer immeasurable environmental services, is alarming. We see the consequences in rising temperatures, declining air quality, and vanishing biodiversity.

The Imperative of Ecological Preservation and NGT Directives

It is crucial to highlight the broader context of our delicate ecosystem's need for preservation. Trees are not just ornamental; they are the lungs of our city, crucial for air purification, oxygen generation, groundwater retention, and temperature regulation. They provide essential habitat for countless species of birds, animals, and insects, contributing to the very fabric of our urban biodiversity. Their preservation is not merely a legal obligation, but a profound moral responsibility we owe to current and future generations.

I must also bring to your attention the significant role of the National Green Tribunal (NGT). The NGT has consistently emphasized the "polluter pays" principle and the need for rigorous environmental impact assessments. While the Karnataka Forest (Preservation) Act, 1976, and the Karnataka Forest (Preservation of Trees) Rules, 1977, mandate compensatory afforestation – specifically, 10 saplings for every tree felled, amounting to 6,260 saplings in this case – mere planting is often insufficient. The survival rate and long-term maintenance of these saplings are critical factors often overlooked.

In light of this, I seek urgent clarification on whether  the Karnataka Forest Department already initiated this compensatory plantation process. If so, could you please provide detailed information on the location, current survival rate, and comprehensive ongoing maintenance plans for the planted saplings? Without transparency on these critical aspects, the very purpose of compensatory afforestation is defeated.

Towards a Sustainable Bengaluru

We are not inherently opposed to thoughtful development. However, we vehemently advocate for a development model that integrates ecological conservation as its cornerstone. Sustainable growth demands that our environmental resources, particularly our irreplaceable trees, are protected, replenished, and nurtured in tandem with urban expansion, not sacrificed for it.

I implore the Forest Department to ensure strict compliance with all afforestation laws and to undertake transparent, long-term planning that truly mitigates the ecological impact of any development project. The citizens of Bengaluru deserve a future where development and nature coexist, rather than being pitted against each other.

Thank you for your immediate and serious consideration of this critical matter. We eagerly await your response and urge a public consultation on this issue at the earliest possible opportunity. Let us work together to safeguard Bengaluru's remaining green heritage.

Sincerely,

Priya Chetty-Rajagopal
