NRIDA and IIM Kolkata Four-Year Rural Roads Impact Study 2026 | ग्रामीण सड़क प्रभाव मूल्यांकन अध्ययन

Why in News?

On 29 September 2026, the Ministry of Rural Development announced that the National Rural Infrastructure Development Agency (NRIDA) and the Indian Institute of Management Kolkata (IIM Kolkata) had signed a Memorandum of Understanding for a four-year longitudinal impact assessment of roads constructed under PMGSY-IV and PM-JANMAN.

The study will examine how improved rural connectivity affects people's livelihoods, mobility, access to markets, employment, income, education, healthcare and other essential services. Its purpose is to generate evidence for future rural infrastructure planning and policy decisions.

Who Signed the Agreement?

The agreement was signed by Aditi Singh, Director General of NRIDA, and Professor Alok Kumar Rai, Director of IIM Kolkata. Rural Development Secretary Rohit Kansal and officials from the Ministry and IIM Kolkata were present.

NRIDA functions under the Ministry of Rural Development and plays an important role in rural road infrastructure development. IIM Kolkata will contribute research and analytical expertise to the impact assessment.

What Is the Duration of the Study?

The assessment will run for four years. Unlike a one-time survey, it will use a longitudinal approach, examining changes in selected locations over time.

The official study design includes a baseline survey before construction, a transition period and an endline survey after construction. This arrangement is intended to help researchers examine how conditions change following rural road development.

Geographical Coverage

The study will cover 10 States and Union Territories, 50 districts, 150 blocks and 250 roads. Approximately 5,000 households will be surveyed.

The selected States and Union Territories are Andhra Pradesh, Assam, Chhattisgarh, Jammu and Kashmir, Jharkhand, Madhya Pradesh, Odisha, Rajasthan, Sikkim and Uttarakhand.

These are the geographical areas identified for the study. They should not be confused with the entire geographical coverage of PMGSY-IV or PM-JANMAN.

Three Stages of the Study

The Ministry specified three stages. The baseline survey, conducted before construction, is allocated 14 months. A transition period of approximately 12 months follows. The endline survey, conducted after construction, is allocated 22 months.

Together, these stages account for approximately 48 months, equivalent to four years.

What Is a Baseline Survey?

A baseline survey collects information about conditions before an intervention takes place. In this case, researchers will examine selected rural communities before the relevant road construction.

Information may include travel time, transport costs, employment opportunities, access to services and household welfare. Baseline information provides a reference point for later comparisons.

What Is an Endline Survey?

An endline survey measures conditions after an intervention. By comparing baseline and endline information, researchers can examine whether indicators have improved, worsened or remained unchanged.

However, changes observed over time cannot automatically be attributed entirely to a road project. Other developments, including economic conditions, public programmes and migration, may also influence outcomes. A rigorous impact assessment must account for such factors where possible.

What Is Longitudinal Research?

Longitudinal research studies changes over a period rather than relying on observations at only one point in time. It is useful for understanding how infrastructure affects communities gradually.

For example, a new road may initially reduce travel time. Over a longer period, it may also influence market participation, business activity and access to schools or health facilities. The proposed study will investigate such relationships using evidence.

What Is PMGSY?

PMGSY stands for Pradhan Mantri Gram Sadak Yojana. It is a Government of India programme focused on rural road connectivity. Rural roads help connect habitations with markets, educational institutions, health facilities and other services.

PMGSY-IV refers to the fourth phase of the programme. The newly announced assessment will examine roads constructed under this phase and the PM-JANMAN initiative.

What Is PM-JANMAN?

PM-JANMAN stands for Pradhan Mantri Janjati Adivasi Nyaya Maha Abhiyan. It is an initiative focused on improving access to essential facilities and services for Particularly Vulnerable Tribal Groups.

Road connectivity is relevant because difficult terrain and inadequate transport infrastructure can restrict access to education, healthcare, markets and government services in remote habitations.

Particularly Vulnerable Tribal Groups

Particularly Vulnerable Tribal Groups, abbreviated PVTGs, are identified groups requiring focused development attention because of significant socioeconomic and geographical disadvantages.

Improved connectivity can potentially support access to essential services, but road development must also consider local ecological conditions, community needs and the protection of vulnerable populations.

Impact on Rural Mobility

Mobility refers to the ability of people and goods to move between locations. Rural road improvements may make travel easier, reduce seasonal isolation and support more reliable transportation.

The study will examine travel time, transport costs and mobility patterns. These indicators can help determine whether new roads are improving practical access rather than merely increasing the length of constructed infrastructure.

Impact on Agriculture

Farmers depend on transport to purchase inputs, move harvested crops and reach markets. Poor road conditions can increase costs, cause delays and restrict access to buyers.

Improved connectivity may make agricultural transportation more reliable and expand market opportunities. The study will assess how rural roads influence agriculture and related economic activities.

Impact on Employment

Roads can influence employment by connecting rural workers with workplaces, training institutions and commercial centres. Better transport may also support local enterprises and non-farm activities.

The assessment will investigate employment opportunities, livelihood changes and income diversification. It will not assume that all road construction automatically creates lasting employment growth.

What Is Income Diversification?

Income diversification occurs when households earn money from more than one economic activity. A rural household may combine agriculture with wage employment, trade, transport or services.

Improved road connectivity may make some additional activities more accessible. The study will investigate whether such changes occur and how they vary across communities.

Impact on Education

Distance and poor transport can create barriers to attending schools and educational institutions. Improved roads may reduce travel difficulties for students and teachers.

The study will assess changes in access to education. Researchers must distinguish improved physical accessibility from other outcomes, such as actual attendance and learning, which may also depend on school quality, household circumstances and other factors.

Impact on Healthcare

Reliable roads may improve access to primary health centres, hospitals, emergency transport and medical supplies.

The study will examine how connectivity affects access to healthcare. Better roads can support healthcare delivery, but the availability of medical staff, medicines and facilities remains essential.

Women's Empowerment and Safety

The official study will also examine women's empowerment and safety. Transport availability and travel conditions can affect women's access to education, employment, healthcare and public services.

The assessment may help identify whether benefits are distributed equally and whether particular barriers remain for women and vulnerable groups.

Migration Patterns

Migration refers to movement from one location to another, temporarily or permanently. Better rural connectivity can affect migration by changing access to employment, markets and services.

The study will examine migration patterns without assuming that road development must necessarily increase or decrease migration. Different communities may experience different effects.

Access to Public and Financial Services

Rural roads may improve access to government offices, banking facilities and other essential services. Physical connectivity can complement digital service delivery, particularly where people must travel for documentation, assistance or transactions.

The study will examine these aspects as part of the broader socioeconomic impact of rural infrastructure.

What Is Evidence-Based Policymaking?

Evidence-based policymaking uses reliable data, research and evaluation findings to inform public decisions. Instead of judging a programme only by expenditure or construction targets, it also examines the outcomes experienced by citizens.

The NRIDA–IIM Kolkata collaboration is intended to provide evidence for programme review, monitoring, identification of implementation gaps and future rural infrastructure planning.

Outputs Versus Outcomes

An output is a direct result of an activity, such as the construction of a road. An outcome is a change that follows, such as reduced travel time or improved access to a market.

Impact assessment goes further by examining broader and longer-term effects on people's lives. This distinction is important in public administration and development economics.

Regional Differences

The selected study areas include different geographical and socioeconomic environments. Road construction in mountainous areas may face different challenges from construction in plains or forested regions.

The study is intended to assess variations across regions and vulnerable groups, which may help policymakers understand why similar infrastructure investments produce different results.

Sustainability of Benefits

A central objective is to examine whether improvements in connectivity lead to sustained socioeconomic gains. Infrastructure may initially provide benefits, but maintenance, climate conditions, transport services and local economic opportunities can influence long-term outcomes.

Assessing sustainability can help identify where additional policy or administrative interventions may be required.

Why the Study Matters for India

Rural infrastructure investment is intended to improve economic opportunity and access to essential services. Measuring long-term results can help governments understand which approaches work effectively and where implementation needs improvement.

The study may support more informed decisions about rural connectivity, resource allocation and development planning.
