Indian Defence Estates Service

The Indian Defence Estates Service (IDES) is an organized Group 'A' central civil service under the , , responsible for the management, administration, and preservation of defence lands and cantonments nationwide. Officers of the service, appointed through the Union Public Service Commission's , serve as trustees for approximately 17.53 acres of defence , handling tasks such as maintaining land records, defending suits, and overseeing civil in areas. The service traces its origins to the establishment of the first in in 1765 and the Cantonments Act of 1924, with the formal department created on December 16, 1926, initially as the Military Lands and Cantonments Service before being redesignated IDES in 1985. Its three-tiered structure comprises the apex-level Defence Estates (DGDE) headquartered in , which advises the on land and cantonment policies; mid-level Principal Directorates at seven commands; and field-level Defence Estates Offices across 39 locations that execute on-ground . Key functions include policy formulation for cantonment boards, land acquisition and utilization, and revenue generation through leasing and monetization initiatives aimed at . While the service has facilitated the expansion of infrastructure amid India's post-independence territorial challenges, it has encountered issues such as land encroachments and disputes over encroachments on defence , necessitating robust legal defenses and modernization efforts like of records. Recent directives emphasize transforming cantonments into , , and sustainable models to balance needs with environmental and civic demands.

History

Origins and Early Development

The establishment of cantonments in British India originated from the need to segregate military stations from civilian areas following the expansion of influence after the in 1757. The first such was founded in 1765 at near Calcutta to house troops and facilitate administration. This practice evolved as the Company, chartered in 1600 and beginning trade in by 1608, required organized land management for garrisons amid territorial acquisitions. Legislative frameworks gradually formalized cantonment governance, starting with the Regulating Act of 1773, which empowered the to regulate administration, including land rules. The provided mechanisms for land transfers within , while the Cantonments Act of 1889 created a for municipal duties such as and taxation. These measures addressed growing administrative complexities, culminating in the Cantonments Act of 1924, which incorporated civilian representation and updated fiscal powers, replacing prior enactments. The Defence Estates Department's direct precursor emerged in the with the appointment of Military Estates Officers to handle land matters independently of military commands. On December 16, 1926, the Governor General-in-Council decided to establish the Department on a permanent basis, marking the formal origin of what became the Military Lands and Cantonments Service. This structure centralized oversight of defence lands and civil functions in cantonments, responding to the demands of an expanding colonial military apparatus spanning over a million acres by the mid-20th century.

Evolution and Renaming

The Indian Defence Estates Service traces its origins to 16 December 1926, when it was established by the colonial government as the Military Lands and Cantonments Service to oversee the administration of military lands, cantonments, and related infrastructure across British India. This initial framework addressed the growing need for centralized management of expansive defence holdings amid colonial military expansions, drawing on earlier ad hoc arrangements for land acquisition and maintenance under acts like the Cantonments Act of 1924. Post-independence, the service adapted to the sovereign Republic of India's defence needs, transitioning into the around 1983 to emphasize national control over inherited colonial-era assets, including the resolution of encroachments and boundary disputes on approximately 17 million acres of defence land. This phase involved integrating pre-existing colonial mechanisms with new statutory frameworks, such as amendments to the , to facilitate land pooling, leasing, and civil-military interface in 62 notified cantonments. In 1985, the service was formally renamed the Indian Defence Estates Service, marking a shift toward a more comprehensive estates-oriented that underscored its evolving role in asset valuation, generation through leasing, and strategic land optimization for modern defence requirements, including development and environmental compliance. This redesignation aligned with broader administrative reforms under the , formalizing the cadre under Group 'A' civil services rules and expanding oversight to include policy formulation for defence urban areas, without altering core statutory powers derived from the Cantonments Act. The renaming did not entail a wholesale restructuring but refined the service's identity to better encapsulate holistic property stewardship amid post-1970s urbanization pressures on defence holdings.

Mandate and Core Functions

Land Management and Acquisition

The Indian Defence Estates Service (IDES), operating under the Directorate General Defence Estates (DGDE), holds custodianship over approximately 18 acres of defence land nationwide, managed through 39 Defence Estates Offices and 4 Assistant Defence Estates Officer offices. This role entails maintaining comprehensive land records to secure proprietary, occupancy, tenancy, and other legal rights of the , including updates to the Military Lands Register and Raksha Bhoomi database. Management further involves defending title suits in courts from lower levels to the , preventing and removing encroachments on defence properties, and handling litigations related to ownership and acquisition disputes. In addition to core custodianship, IDES oversees ancillary functions such as granting leases, licences, and permissions for uses like building plans or temporary exhibitions; reclassifying ; mutating records; renewing tenures; and disposing of surplus assets including trees, usufructs, camping grounds, and obsolete airfields. Revenue generation from activities like shopping complexes on defence also falls under this purview, alongside conversions from leasehold to freehold status where authorized. Land acquisition constitutes a primary function, with DGDE serving as the nodal agency for procuring immovable properties required by defence establishments such as the , , , and (DRDO). The process commences with in-principle approval from the , followed by formulation of a detailed proposal by a Board of Officers advised by the local Defence Estates Officer (DEO). The DEO then liaises with the Land Acquisition Collector and authorities to issue statutory notifications under the applicable land acquisition legislation, typically involving proceedings under Sections 9 and 11 for public notification and hearing objections. Subsequent steps include obtaining formal government sanction, raising demands for acquisition to the District Collector or , declaration of the compensation award, deposit of funds, and final of to the user service. DGDE advises the on policy matters, processes rehabilitation proposals for project-affected families, and defends related court cases up to the apex level, ensuring compliance with compensation decrees. Complementary mechanisms include hiring or requisitioning land through state governments to address urgent defence needs without permanent acquisition.

Cantonment Administration and Civil Governance

Cantonment Boards serve as the primary institutions for local self-governance in India's 61 notified cantonments, operating under the Cantonments Act, 2006, which succeeded the 1924 Act to consolidate administration, enhance democratization, and improve financial autonomy. These boards manage for mixed military and civilian populations, balancing defence requirements with civil needs such as , ecological preservation, and development amid land and resource constraints. The Defence Estates (DGDE), an inter-services organization under the , oversees policy formulation, rule-making, grant assessments, and monitoring of these boards to ensure compliance with central directives. Each is structured democratically, with the military Station Commander serving as ex-officio President and an equal number of elected civilian members alongside nominated and ex-officio representatives. The (CEO), typically an officer from the (IDES), acts as Member-Secretary and executive head, responsible for day-to-day operations including staff management, budget execution, and enforcement of board resolutions. IDES officers in these roles exercise quasi-judicial powers under the Cantonments Act for matters like property disputes and evictions, while also handling litigation and welfare programs. In civil governance, Cantonment Boards, supported by IDES oversight, deliver essential services such as water supply, sanitation, road maintenance, public health initiatives, and facilities, often extending schemes to residents. Boards levy taxes and fees to fund these activities, categorized by population into four classes for tailored , with DGDE providing financial grants and technical guidance to address fiscal shortfalls. IDES officers ensure integration of civil with priorities, managing unauthorized occupations via the Public Premises (Eviction of Unauthorized Occupants) Act, 1971, and promoting sustainable urban ecosystems as part of ongoing modernization efforts. This framework maintains cantonments as self-sustaining entities distinct from municipal corporations, prioritizing defence land integrity while fostering civilian welfare.

Organizational Framework

Directorate General Defence Estates

The Directorate General Defence Estates (DGDE), headquartered in , functions as the apex administrative body and headquarters of the Indian Defence Estates Service (IDES). It provides advisory inputs to the and the Service Headquarters of the , , and on all cantonment administration and defence land-related matters. The organization oversees the implementation of policies, rules, and regulations governing these areas, including the Cantonments Act, 2006. Led by the in the apex pay scale, the DGDE is currently headed by Smt. Shobha Gupta, a 1990-batch IDES officer who assumed charge on October 1, 2025. The leadership structure includes one Senior Additional Director General at the Higher Administrative Grade level, supported by six Principal Directorates aligned with the Central, Eastern, Northern, Southern, South-western, and Western Commands. These directorates coordinate with field operations to ensure effective policy execution across India's defence estates. Core responsibilities encompass the custodianship of approximately 17.53 acres of defence land, managed through 39 Defence Estates Offices and 4 Estates Officer Circles. This includes land acquisition for purposes, resettlement and of affected populations, and the hiring or requisitioning of immovable properties. The DGDE maintains comprehensive land records to safeguard the Ministry of Defence's legal entitlements and supervises 61 Boards, which operate as local self-government entities under the Cantonments Act, 1924, delivering civic administration and welfare services. In legal domains, the DGDE manages litigation concerning land acquisition, ownership disputes, and encroachments, exercising quasi-judicial powers under statutes such as the Public Premises (Eviction of Unauthorized Occupants) Act, 1971. It ensures compliance with eviction procedures for unauthorized occupants on defence premises and advises on regulatory frameworks to prevent land misuse, thereby upholding interests through vigilant estate governance.

Regional and Field Operations

The regional operations of the Indian Defence Estates Service (IDES) are coordinated through six Principal Directorates, each aligned with a command of the and headed by a Principal Director, a senior IDES officer in the Higher Administrative Grade. These directorates provide advisory support to General Officers Commanding-in-Chief, Flag Officers Commanding-in-Chief of the , Air Officers Commanding-in-Chief, and other entities such as Factories and the on defence land matters. The Principal Directorates are located at for Central Command, for Eastern Command, for Northern Command, for Southern Command, for South-Western Command (established in 2006), and for Western Command. In their jurisdictions, they manage land acquisition, requisitioning, hiring of properties, and civil administration within cantonments, while exercising statutory powers under the Cantonments Act, 2006, including oversight of Cantonment Boards. Field operations are executed via 39 Defence Estates Offices (DEOs) and 4 Circles of Assistant Defence Estates Officers (ADEOs), supervised by the Principal Directorates to ensure decentralized implementation of national policies. DEOs handle localized tasks such as surveying and demarcating defence lands, processing leases and allotments, resolving encroachments, and coordinating rehabilitation for persons displaced by land acquisitions under laws like the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013. Examples include DEOs at , Allahabad, and under Central Command, which interface directly with local military units and civil authorities for routine estate maintenance and dispute resolution. ADEO Circles focus on sub-regional coordination, particularly in areas with clustered cantonments or high-volume land transactions, supporting the 61 operational cantonments across . This tiered field structure enables responsive operations while maintaining uniformity in legal and fiscal compliance.

Recruitment and Selection

UPSC Examination Pathway

The Indian Defence Estates Service (IDES) recruits its officers primarily through the (CSE), an annual competitive examination conducted by the (UPSC). This pathway integrates IDES as one of the Central Civil Services, allowing successful candidates to allocate it based on their rank and service preferences following the final merit list. The CSE serves as the sole entry mechanism for direct recruitment into IDES at the junior time-scale level, with no separate departmental examination required. Eligibility for the CSE, applicable to IDES aspirants, mandates that candidates possess a from a recognized university or equivalent qualification, with the exam open to final-year students who complete their degree before the mains commencement. The age limit is 21 to 32 years as of August 1 in the year of the examination, with relaxations of up to 3 years for Other Backward Classes (OBC), 5 years for Scheduled Castes/Scheduled Tribes (/), and 10 years for Persons with Benchmark Disabilities (PwBD). Nationality requirements stipulate citizenship for IDES allocation, though certain non-citizens (e.g., subjects of or ) may appear subject to service-specific restrictions. The number of attempts is limited to 6 for general category candidates, 9 for OBC, and unlimited for SC/ST up to the age ceiling. The CSE comprises three successive stages: Preliminary Examination (objective-type, qualifying for mains), Main Examination (descriptive papers totaling 1750 marks across nine papers, including essay, , and optional subjects), and (interview worth 275 marks). IDES-specific preparation emphasizes of , , and defence-related administration, though the syllabus remains uniform for all services. Approximately 10-15 vacancies for IDES are notified annually within the CSE, allocated post-interview based on the candidate's all-India rank, category-wise merit, and preference for IDES over other services like IAS or IPS. Selected candidates undergo medical verification and character assessment before empanelment. Post-selection, IDES officers are appointed on probation, with service allocation formalized via the UPSC's recommendation to the . This merit-cum-preference system ensures that only candidates ranking sufficiently high and opting for IDES secure entry, reflecting the service's specialized focus amid competition from more popular civil services.

Promotional Quotas and Eligibility

The recruitment to the Indian Defence Estates Service (Group 'A') allocates 25% of vacancies in the Junior Time Scale for filling by promotion, with the remaining 75% through direct recruitment via the Union Public Service Commission Civil Services Examination. This quota structure, as revised in the Indian Defence Estates Service (Group 'A') Rules, 2025, supersedes prior provisions to align with evolving administrative needs in defence land management. Promotees are drawn exclusively from Group 'B' Gazetted officers within the Defence Estates Organisation, comprising Chief Executive Officers (CEOs) and Assistant Defence Estates Officers (ADEOs), reflecting the service's emphasis on internal expertise in administration and estate operations. The selection maintains parity between these feeder cadres, ensuring balanced representation from executive and estates-specific roles. Eligibility for consideration mandates at least five years of regular service in the holding Group 'B' post, inclusive of the probationary period, alongside clearance of any mandatory departmental examinations or training programs conducted by the National Institute of Defence Estates Management. Candidates must also possess unblemished vigilance records and meet fitness standards as determined by medical boards, with no upper age limit specified beyond general norms. The promotion process employs a selection overseen by a Departmental Promotion Committee (DPC), convened periodically by the , which evaluates eligible officers based on annual performance appraisals, , and overall merit without reservations altering the quota percentage. This mechanism prioritizes officers demonstrating proficiency in land acquisition, civil governance, and , core to IDES functions.

Training and Capacity Building

Induction Training at NIDEM

The induction training for Indian Defence Estates Service (IDES) officers occurs at the in , immediately following their foundational course at the . This phase professionalizes probationers in the specialized domain of defence estates, emphasizing practical competencies for and cantonment governance. Both direct recruits and promotee officers undergo this training, which forms a critical component of their period leading to service confirmation. The curriculum centers on , municipal administration, acquisition processes, and related regulatory frameworks, delivered through workshops, seminars, and targeted sessions. These activities build expertise in handling defence lands, encroachments, and civil-military interfaces, preparing officers for roles in estates oversight and operations. NIDEM, established in 1982 and now housed at Raksha Sampada Bhawan, integrates modern facilities to support this training, which also extends to select military personnel from the , , and . Recent programs illustrate the institute's operational rhythm; for instance, the 2023 batch's induction concluded on August 2, 2024, with a valedictory by a official, while the 2024 batch wrapped up in early September 2025. Post-training, officers are typically allocated as Chief Executive Officers in cantonments, applying acquired skills to on-ground administration. The program, overseen by a at Administrative Grade level with supporting Directors, ensures alignment with departmental mandates under the Defence Estates.

Specialized and In-Service Programs

In-service training programs for Indian Defence Estates Service (IDES) officers are primarily conducted at the National Institute of Defence Estates Management (NIDEM), focusing on updating skills in , regulatory frameworks, and emerging challenges like encroachments and acquisitions. These programs serve both recruits and promotees, aiming to build capacity for mid-career and senior roles through targeted modules on municipal governance, legal compliance, and . A key component is the end-of-probation Phase-II , which integrates from initial postings with advanced on practices; for example, the program for the 2023 batch ran from June 24 to July 31, 2024. Specialized short-term courses address niche areas, such as a two-day on tendering processes and store concluded on September 29, 2025, to improve and handling in cantonments. NIDEM further offers workshops and seminars on land acquisition, survey techniques, and inter-agency coordination, often involving officers from the , , and to resolve domain-specific disputes. These initiatives, evolving since NIDEM's in , ensure officers remain equipped for evolving policy demands without disrupting service continuity.

Career Progression and Roles

Initial Postings and Allocations

Upon successful completion of the UPSC Civil Services Examination and the mandatory foundation course at the Lal Bahadur Shastri National Academy of Administration (LBSNAA), IDES probationers proceed to specialized induction training at the National Institute of Defence Estates Management (NIDEM) in Delhi, typically lasting around six months in the initial phase. This training equips officers with knowledge in defence land management, cantonment administration, legal frameworks like the Cantonments Act, and estate development practices. Following the training phase, IDES officers enter a probationary period, during which they receive their initial field postings, often as Assistant Defence Estates Officers (ADEOs) or in junior roles attached to Cantonment Boards or Defence Estates Circles. These entry-level assignments focus on practical exposure to core functions, including land acquisition, encroachment prevention, revenue collection from defence properties, and coordination with military authorities on estate matters. Confirmation in the service occurs after successful probation, which includes end-of-probation training combining institutional modules and field attachments lasting approximately two months. Initial postings frequently involve challenging terrains or remote cantonments to build foundational skills in autonomous land governance as agents of the . Allocations for initial postings are managed by the Directorate General Defence Estates (DGDE), which divides responsibilities across six Principal Directorates corresponding to army commands: Central, Eastern, Northern, Southern, South-Western, and Western. Officers are assigned based on service requirements, vacancy availability, and rotational policies to ensure balanced exposure across regions, without a state-specific cadre preference system akin to All India Services. Early assignments prioritize smaller cantonments or sub-divisional estate offices, where probationers assist senior Defence Estates Officers (DEOs) or Chief Executive Officers (CEOs) in tasks such as lease management, boundary demarcation, and compliance with environmental regulations for defence lands totaling over 17 lakh acres. This decentralized allocation structure supports DGDE's oversight of 62 cantonments and facilitates officers' progression to independent charges as DEOs or CEOs within 1-2 years post-probation.

Deputations and External Appointments

Officers of the Indian Defence Estates Service (IDES) are permitted to serve on deputation to enhance administrative experience and cadre mobility, as managed by the Directorate General Defence Estates under the . Such deputations are regulated by the Indian Defence Estates Service (Group ‘A’) Rules, 2013, which outline provisions for temporary postings outside the core service cadre. Eligible deputation avenues include assignments to ministries and departments, State Governments, autonomous organizations, subordinate organizations, (PSUs), and positions under the Central Staffing Scheme administered by the Department of Personnel and Training. These postings typically involve roles leveraging expertise in , , and regulatory compliance, with durations generally limited to three years unless extended for specific schemes like the Central Staffing Scheme. Examples of such deputations include an IDES officer serving as at the Lal Bahadur Shastri National Academy of Administration (LBSNAA) in , as documented in the service effective July 1, 2025. Deputations to PSUs or autonomous bodies often focus on estate-related advisory functions, though specific allocations depend on cadre reviews and vacancy notifications issued by the cadre controlling authority.

Reforms and Strategic Initiatives

Cantonment Restructuring and Mergers

In 2023, the Indian Ministry of Defence announced plans to restructure all 62 cantonments by excising civil areas and merging them with adjacent urban local bodies (ULBs), converting the remaining military zones into dedicated stations free from dual civil-military administration. This initiative, rooted in recommendations dating to 2018 from the Indian Army, seeks to alleviate the military's burden of civilian governance, enable civilians to access state welfare schemes without restrictions, and facilitate urban development on approximately 651 square kilometers of civil land within cantonments. The Directorate General Defence Estates (DGDE), under which Indian Defence Estates Service (IDES) officers serve, coordinates the excision, ensuring the transfer of land records, assets, and liabilities while safeguarding military security interests. The restructuring process involves gazette notifications denotifying civil areas, followed by state government-led mergers with municipalities, as outlined in directives issued to states in July 2023 for 58 cantonments. IDES officers, functioning as estate and military estates officers, play a pivotal role in demarcating boundaries, resolving tenure disputes under legacy laws like the Cantonments Act of 1924, and advising on the retention of core defence lands spanning over 18 lakh acres nationwide. The first implementation occurred at Khasyol Cantonment in April 2023, where civil areas were merged with local panchayats, setting a precedent for nationwide rollout. By March 2024, civil areas in 10 cantonments—including , Subathu, and —had been denotified and transferred to state bodies, with further progress in 2025 including approvals for mergers in and cantonments with the in July. As of September 2025, 61 cantonments remained under transition, with extensions granted to civilian board members in 56 locations pending completion. The reforms address longstanding issues such as restricted civilian property rights and inter-community frictions but pose challenges, including the absorption of around 14,000 civilian employees into municipal payrolls and potential fiscal strains on ULBs from expanded jurisdictions. In September 2025, Defence Minister directed IDES officers to integrate restructuring with modernization efforts, targeting smart, green military stations by 2035 through digital tools like e-Chhawani 2.0 and sustainable infrastructure. This aligns with broader defence land optimization, though critics note risks of unregulated construction eroding buffers around strategic assets.

Monetization, Sustainability, and Modernization Efforts

The (IDES) has pursued of surplus defence lands as a means to generate for modernization, leveraging approximately 17.5 acres of underutilized holdings. In 2021, the initiated processes to commercially exploit these assets, drawing on recommendations from the Sumit to identify and surplus parcels without compromising needs. Under the revised Defence Lands Policy, lands can be leased or licensed for public projects with premiums and rents calibrated to usage type, enabling proceeds to fund a non-lapsable modernization corpus. This approach targets assets like the 39 legacy farms, integrating into the to support and infrastructure upgrades. Sustainability efforts emphasize transforming cantonments into eco-friendly urban models, with Defence Minister directing IDES officers in September 2025 to achieve carbon-neutral status by 2030 through adoption and reforms. Initiatives include integrating grids, , and resource-efficient planning to reduce emissions and enhance resilience, aligning with broader national goals like by freeing viable lands for housing without ecological trade-offs. By 2035, cantonment boards are targeted to evolve into smart-green ecosystems, prioritizing preservation alongside urban functionality. Modernization drives focus on digital overhaul and administrative , including land record and GIS-based auditing to streamline across 17.5 acres. The "Manthan 2025" conference, convened in 2025, outlined adoption of AI-driven tools for predictive and , fostering financial for and cantonment entities through revenue-sharing models. These reforms aim to mitigate encroachments via real-time monitoring while optimizing asset utilization, with ongoing policy tweaks to balance fiscal gains against operational imperatives.

Challenges, Criticisms, and Impacts

Corruption Allegations and Enforcement Actions

The Indian Defence Estates Service (IDES) has faced multiple allegations of primarily related to the mismanagement of defence lands, including illegal allotments, fraudulent sales, and acceptance of bribes for approvals in areas. These issues stem from the service's oversight of vast tracts of land, valued in thousands of crores, where discrepancies in records and with land sharks have enabled encroachments and unauthorized transfers. A 2010-2011 Comptroller and Auditor General () performance audit on Defence Estates Management highlighted large-scale irregularities, such as unmonitored funds and irregular land dealings, contributing to potential losses exceeding Rs 1,277 crore in related scams. Enforcement actions have predominantly involved investigations by the (CBI), targeting IDES officers for violations under the Prevention of Corruption Act. In March 2017, the CBI registered a case against S. Prabhakaran, an IDES officer and former CEO of a , for alleged linked to illegal hoarding and unauthorized activities during his tenure. Similarly, on June 19, 2024, the CBI booked Ajay Kumar, another senior IDES officer and former Nashik CEO, for approving a layout plan while illegally purchasing adjacent cantonment plots, prompting searches at his premises for evidence of misconduct. Notable convictions include a 2013 Pune court ruling sentencing IDES officer Reddy to two years' rigorous imprisonment for demanding and accepting a bribe of Rs 50,000 on October 6, 2009, to expedite a land-related process. In the Adarsh housing society scam, eight Defence Estates officers were implicated in 2011 for irregularities in land allotment approvals, as flagged by CAG scrutiny of membership lists and procedural lapses. Broader probes, such as those into fraudulent sales of old grant bungalows in Pune cantonments detected in 2023-2024, led to transfers of whistleblowing officials and ongoing CBI scrutiny, underscoring persistent challenges in land governance despite audit recommendations for stricter oversight.

Land Encroachments, Disputes, and Security Implications

Encroachments on defence lands managed by the Indian Defence Estates Service (IDES) have persisted as a significant issue, with approximately 10,354 acres reported as encroached across as of August 2024. accounted for the largest share at 1,778.9 acres, followed by with 1,757.979 acres, reflecting uneven distribution influenced by , urban expansion, and lax in certain regions. Historical data from Comptroller and Auditor General () audits indicate a rise in encroachments from 6,903 acres in 1997 to 14,539 acres by 2009, underscoring delays in of land records and inadequate demarcation as causal factors. IDES officers, through Defence Estates Offices (DEOs), conduct surveys and initiate evictions, but progress remains hampered by unauthorized occupations by individuals, former defence personnel, and even state entities. Land disputes often escalate into protracted legal battles, with 862 encroachment cases pending in courts as reported in parliamentary records. The has faced resistance from state governments and private entities, complicating eviction drives; for instance, in October 2025, the Centre informed the of ongoing efforts against such encroachments, including 1,575 acres held by ex-servicemen and others. IDES personnel handle these through civil suits and coordination with revenue departments, but CAG critiques highlight exploitation via unauthorized leases and failure to update records, leading to revenue losses estimated in crores annually. Recent interventions, such as in July 2025, have urged audits and deployment of (JAG) officers for faster resolutions, pointing to irregularities in land allotments that fuel disputes. These encroachments carry direct security implications, acting as "silent threats" by eroding buffer zones around military installations and enabling potential surveillance or sabotage. Proximity of civilian structures to sensitive areas compromises operational secrecy and rapid mobilization, as evidenced by cases near Delhi's airport where reclaimed land in May 2025 restored perimeter integrity. Vice President Jagdeep Dhankhar emphasized in July 2024 the need for technological tools like AI for encroachment detection to mitigate risks from legal delays and urban sprawl. Persistent disputes also strain IDES resources, diverting focus from core defence management to litigation, thereby weakening overall national security posture amid rising geopolitical tensions.
