One Parcel, One Identity: Building the Foundation of Digital Land Governance

Bangladesh has spent decades creating land records. Yet one question remains difficult to answer: which exact parcel of land are we talking about?

The same property may be identified by a dag number in one survey, another reference in a later survey, a khatian entry, a deed schedule, a mutation record, a housing-project plot number or a municipal holding number. Each serves a purpose, but they do not always point through a common digital identity to the physical land. The next stage of reform should move beyond digitising records and identify the land itself. A Unique Land Parcel Identification Number, or ULPIN, can provide that foundation. Its value is in becoming a persistent identity through which dag, khatian, deed, mutation, tax, acquisition, planning and other property information can be linked to the same parcel.

Bangladesh’s land system has traditionally been built around textual records and periodic surveys. A Land Geospatial Data Infrastructure (LGDI) approach can move it toward a parcel-based, georeferenced and continuously updated system connecting land records and services around the same spatial unit, while supporting valuation, mortgage and planning.

Bangladesh’s land system has traditionally been built around textual records and periodic surveys. A Land Geospatial Data Infrastructure (LGDI) approach can move it toward a parcel-based, georeferenced and continuously updated system connecting land records and services around the same spatial unit, while supporting valuation, mortgage and planning.

Why Geometry Matters
A land record may correctly state an area without showing exactly where that area lies. Suppose a person transfers 20 decimals from a 100-decimal dag. The deed may state 20 decimals and mutation may record the same quantity. But unless the transferred portion is spatially identified, the system still cannot answer: which 20 decimals?

A modern land system must therefore connect four things: the right-holder, ownership chain, parcel identity and parcel geometry. A parcel should be understood not merely as a textual record or area figure, but as a geospatial object linked to legal, administrative and economic attributes. For cities, even parcel identity is not enough. One urban parcel may contain a multi-storey building with apartments, shops and offices, each with separate owners, mortgages, transactions and tax liabilities. Modern urban administration needs a hierarchy from land parcel to building and individual property unit.

A development authority may retain its plot number, a city corporation its holding number, the registration system its deed reference and a bank its mortgage reference. These need not disappear; they need to be digitally linked to the parcel, building and property unit. This matters for taxation, mortgage lending, valuation and development control.

A Useful International Lesson
South Korea shows how a parcel-based cadastral system can support a mature property-information environment. Parcel number, location, area and boundary are maintained around the spatial unit. The lesson is not to copy Korea’s numbering method, but to value a stable spatial reference for organising property information. Even advanced cadastral systems require correction and resurvey where older maps no longer correspond with conditions on the ground. Bangladesh therefore need not survey every parcel to the highest precision before a national parcel framework can begin. It can take the lessons learned from Pakistan’s Punjab land reform initiative under World Bank’s PULSE project.  

Fit-for-Purpose, Not One-Size-Fits-All
Traditional cadastral surveying remains legally important, but large-scale survey operations can take many years. Meanwhile, land changes through sale, inheritance, subdivision, acquisition, construction, erosion and accretion.

A national land system cannot depend on periodic survey alone. The LGDI approach points toward a hybrid model using existing cadastral maps, orthophoto or satellite imagery, drone survey, georeferencing, selective field verification with citizen claim and validation. This reflects fit-for-purpose land administration: use the accuracy that purpose and risk require, and improve it progressively.

A clearly bounded rural parcel may initially be established through existing cadastral evidence, imagery and local verification. An uncertain boundary may require mobile GNSS verification, while a disputed high-value urban parcel or infrastructure corridor may require higher-precision survey. The principle is straightforward: accuracy should increase where risk requires it, but national coverage should not wait for perfection. Fit-for-purpose programmes show that imagery, mobile technology and participatory mapping can reduce costs compared with conventional high-precision parcel-by-parcel surveying. Bangladesh should therefore develop cost and accuracy classes based on purpose, parcel density, land value, legal risk and available data.

Citizens Can Help Identify; the State Must Verify
Citizen participation can accelerate parcel mapping, but a boundary drawn by a citizen should not automatically become legal. A better model is participatory parcel mapping: existing records and imagery prepare a draft map; owners and neighbours review boundary and ownership information; claims and objections are submitted; doubtful cases receive official verification; and the result is finalised only after notice and dispute-resolution processes.

The principle is simple: citizens can help identify; the State must verify and certify.

Punjab, Pakistan offers a relevant regional comparison. Under the World Bank-supported PULSE programme, digital cadastral information is being linked with land records and field verification. Its “Green Property Certificate” initiative moves beyond map digitisation towards a verified property record supported by identity, possession and spatial verification.

For Bangladesh, a practical sequence could be: existing records → georeferenced parcel → georeferenced parcel identification of Government land → citizen/community claim andvalidation → ownership-chain verification → objection resolution → field verification where required → government-certified output.

Bangladesh could develop this progression through a proposed “Parcel Title Certificate”.

More Than a Renamed Khatian
Such a certificate should not simply be a renamed khatian, nor should it automatically be treated as conclusive title without legal reform. Its value would come from bringing together, after verification, parcel identity, geospatial representation, current right-holder, ownership shares, source of right, relevant deeds, mutation references and parcel history in a digitally verifiable record. For urban property, the same architecture could extend to the building and individual property unit.

The benefits would be considerable. A buyer could identify the actual parcel or apartment being purchased. A bank could identify the property offered as collateral. A city corporation could link holdings and building units to property taxation. A development authority could connect planning approvals to the cadastral parcel. Acquisition agencies could identify affected parcels earlier. Courts could examine ownership and parcel history together. Government land and hazard information could also be monitored spatially.

Most importantly, every future transaction could be attached to the same property. That creates the foundation for something Bangladesh still lacks: an integrated national land and property valuation framework. Valuation cannot work well if the property being valued cannot be identified consistently. Neither can property taxation, mortgage analytics or land-market intelligence.

The reform is therefore larger than ULPIN. Bangladesh needs a national property identity framework in which the chain is clear: person/entity → legal relationship → spatial parcel → built asset → individual unit.Around that relationship, registration, succession, mutation, taxation, valuation, planning, mortgage, acquisition and other authorised services can operate without losing their statutory roles.Bangladesh has already digitised much land information. The next step is to organise it around the land itself.

Ownership certainty answers who holds the right. Parcel identity answers exactly which land that right relates to. Clear institutional responsibility should also be defined for maintaining this national geospatial land framework, potentially through a designated Land Geospatial Authority.

Once both can be answered reliably, Bangladesh can move from document digitisation toward true digital land governance. One parcel, one identity is not the destination. It is the foundation for secure ownership, modern taxation, property transactions, investment and the future management of Bangladesh’s cities.
