Introduction (Context)

Migration is a demographic process involving the movement of people from one place to another, either temporarily or permanently. In India, internal migration constitutes a significant proportion of the population, with about 28.9% migration rate (2021). A significant portion of migration in India is for marriage, especially among women. Around 10%, however, migrate for work. This number is significantly higher in certain northern and eastern States such as Bihar. With an ever-increasing number of migrants travelling from poorer to richer areas in search of employment, the number of those effectively disenfranchised will only increase, unless mechanisms are put in place to facilitate voting by migrants. This undermines universal adult franchise, a foundational principle of Indian democracy. In the 2024 Lok Sabha elections, Bihar recorded only 56% turnout, far below the national average of 66%. This is significantly attributed to out-migration.

Types of Migration

1. Intra-State Migration: Movement within the same state (≈85% of total migration).
2. Inter-State Migration: Movement between states.
3. Rural-Urban Migration: Dominated by seasonal or semi-permanent job seekers.
4. Marriage-Related Migration: Predominantly involving women.
5. Distress Migration: Forced movement due to poverty, conflict, or environmental reasons.

Issues Faced by Migrants in Voting

• Most migrants move temporarily or seasonally to other regions (often cities or different states) for work or family reasons. During elections, many are unable to return to their original place of residence, where they are registered as voters. As a result, they are effectively disconnected from the voting process in their home constituencies.
• Migrants, especially those working in the informal sector, often live in temporary housing or slums without proper documentation. Without proof of residence (like rent agreements or utility bills), they find it difficult to update their address on the electoral roll, which is a prerequisite for transferring voting rights to their new location.
• Because migrants are often not permanently settled, they are frequently left out of electoral rolls at both ends:

• • Source (native place): They may have moved long ago or may be away during the time of voting.
  • Destination (current location): They are usually not enrolled due to temporary status or lack of documentation.
    This double exclusion leads to their political invisibility.

• Many migrants are not aware of the procedures to shift or update their voter registration. Even if they are, the process involves filling out forms, visiting government offices, and providing proofs — all of which can be time-consuming and complicated, especially for daily wage workers or those with limited literacy.
• There are no targeted campaigns or support systems by the Election Commission of India (ECI) focused on migrants. Unlike efforts made for other voter groups (e.g., women, senior citizens), migrants do not receive focused awareness drives, mobile registration camps, or facilitation services.
• Many migrant workers do not get paid leave on polling days. Since voting usually happens in their native place, travelling long distances without financial support or leave options becomes impractical. As a result, many skip voting, especially those in daily-wage or informal jobs.

Why voting rights are important?

• Migrants are citizens and deserve equal participation in the democratic process. Enabling them to vote ensures their representation in policymaking and upholds the principle of universal adult franchise.
• When migrants can vote, they gain the power to hold governments accountable for their rights and welfare — such as fair wages, housing, healthcare, and social security.
• High out-migration states like Bihar and Uttar Pradesh often see low voter turnout. Enabling migrants to vote helps correct this imbalance and ensures fair political weight to these regions.
• Many women migrate after marriage and remain unregistered voters. Facilitating their enrolment in new locations increases their political participation and voice in decision-making.

Mechanisms to Enable Migrant Voting

1. Improved Access for Intra-State Migrants

• To improve voting access for intra-State migrants, especially those in the informal sector, the government must strictly enforce statutory polling-day holidays. This would ensure that workers are not forced to choose between their wages and their right to vote. 
• Additionally, subsidized or free transport services on and before polling day would make it easier for migrants to return to their home constituencies to vote. 
• State-wide awareness campaigns and the setting up of facilitation centres could help inform and guide migrant workers about voting procedures, dates, and their rights.

2. Remote Electronic Voting Machines (RVMs)

• The Election Commission of India (ECI) piloted Remote Electronic Voting Machines (RVMs) in 2023 to address the needs of inter-State migrants. These machines were specially designed to handle voting for up to 72 constituencies from a single location. 
• However, the RVM proposal faces several challenges. 

• Political parties have raised concerns about transparency and the credibility of the machines. 
• Logistically, managing deployment, ensuring secure pre-registration, and verifying migrant identities pose significant hurdles. 
• There is also the difficulty of preventing duplication and ensuring the integrity of the process when migrants are spread across states..

3. Postal Ballots for Migrants

• This system is already being implemented by the ECI for members of the armed forces. An extension of this model could help many migrants. 

• The ECI would require migrants to register with the body well in advance, so the postal ballots can be issued. 

• Operationally, this appears to be the easier form of remote voting to implement. 

• However, the ECI would have to organise registration, issue ballot papers, and despatch these ballots to counting centres after voting all major administrative efforts.

4. Changing Constituency Based on Residence

• For long-term migrants who have lived in one place for six months or more, the option of changing their voting constituency to the new place of residence could be offered. This would require valid documentation proving local residence. 

• The key advantage of this method is that it allows representation based on current residence and concerns, encouraging civic integration of migrants into their host communities. 

• However, this option may face political resistance from local residents and parties, who may fear demographic shifts. There is also a risk that migration could become politicised if seen as a tool to influence local electoral outcomes.

5. Gender-Focused Electoral Drive

• A significant portion of female migrants move due to marriage, and many remain unregistered in their new constituencies. This leads to their exclusion from the electoral process. 
• Special enrolment drives targeted at urban and peri-urban areas where many of these women settle can help address this gap. Such drives should include door-to-door campaigns, local awareness programs, and coordination with local authorities to ease documentation and registration processes for women voters..

6. Adopting a Mixed Approach

• No single mechanism fits all migrants due to their heterogeneous nature.
• A composite strategy using RVMs, postal ballots, improved access, and constituency change can enable large-scale inclusion.
• ECI must work with State governments, employers, and civil society to ensure proper implementation.
• Leveraging technology, creating portable voter ID systems, and pre-poll registration portals can simplify processes.

Conclusion

Migrants are economic contributors, but remain politically invisible. Enabling their participation in elections is not just a logistical challenge, but a democratic imperative. Bridging this gap through well-designed, inclusive electoral reforms will strengthen Indian democracy and uphold the spirit of universal adult suffrage enshrined in the Constitution.

Mains Practice Question

Q “Political inclusion of migrants is a necessary step towards economic justice.” Analyse. (250 words, 15 marks)

Introduction (Context)

• India faces a growing water crisis affecting economic growth, agriculture, cities, and public health.
• The country holds 18% of the world’s population but has only 4% of global freshwater resources.
• Water stress is aggravated by population growth, mismanagement, pollution, and climate change.
• The crisis is already evident through falling water tables, erratic rainfall, and urban shortages.

Current Status and Alarming Indicators

• According to NITI Aayog (2018), nearly 600 million Indians face high to extreme water stress.
• By 2030, India’s water demand may double, creating a 40% supply gap.
• India ranks 13th among the world’s 17 most water-stressed countries (World Resources Institute).
• Over 60% of irrigation and 85% of drinking water depends on groundwater, which is fast depleting.
• The 2024 Groundwater Quality Report found 70% of India’s water sources are contaminated.

Climate Change and Its Impact on Water Resources

• Climate change has increased the unpredictability of monsoons vital for 55% of India’s agriculture.
• A 2024 CEEW study found 55% of tehsils saw a 10% increase in extreme rainfall, triggering floods.
• Simultaneously, 33% of India’s land is drought-prone, with declining soil moisture in 48% of the area (Conscious Planet, 2024).
• Himalayan glaciers are melting faster, affecting rivers like the Ganga and Indus that support millions.
• The World Bank projects that climate-related water scarcity could cut India’s GDP by up to 12% by 2050.

Agricultural Vulnerability and Water Mismanagement

• Agriculture uses 80% of India’s freshwater, making it most exposed to water shortages.
• The Economic Survey (2018–19) reported that a 100mm drop in rainfall reduces farmer income by 15% (kharif) and 7% (rabi).
• Climate change could reduce agricultural incomes by 15–18%, and by up to 25% in unirrigated regions.
• Water-intensive crops like rice and sugarcane continue to dominate due to price and policy incentives.
• Micro-irrigation, which can reduce water use by 50%, covers only 9% of cultivated land.
• The Atal Bhujal Yojana promotes groundwater management but covers only 8,000 gram panchayats in 7 states — inadequate for the scale of the crisis.

Urban Water Distress

• Cities like Bengaluru, Chennai, and Delhi are facing seasonal water shortages and infrastructure failures.
• In 2019, Chennai’s reservoirs dried up completely, leaving millions without water access.
• NITI Aayog predicts that 21 cities, impacting over 100 million people, could deplete groundwater by 2030.
• Urban over-extraction, lack of rainwater harvesting, and poor planning exacerbate the problem.

Public Health and Water Quality Concerns

• Contaminated water causes around 2,00,000 deaths annually from waterborne diseases (NITI Aayog, 2018).
• Fluoride and arsenic affect 230 million people across 19 Indian states.
• Untreated sewage continues to pollute rivers like the Yamuna, making them unsafe for use.
• The World Bank’s “One Health” model — integrating environmental, animal, and human health — could save billions, but implementation is sluggish.

Existing Policy Framework and Gaps

• The National Water Mission aims to increase water-use efficiency by 20% by 2025, but lacks tracking systems.
• CEEW has proposed water accounting to monitor savings and direct water to critical sectors.
• India’s adaptation funding is only ₹260 per capita (2019–20), compared to ₹2,200 for mitigation.
• Financial tools like climate bonds and the 2023 Green Credit Programme can help mobilize funds.
• International partnerships, such as the World Bank’s $1 billion dam rehabilitation and ADB’s $50 million loan for Meghalaya’s water harvesting, show promise.
• However, the global water financing gap is $6.7 trillion by 2030 — demanding private sector involvement similar to models in Chile and Peru.

Way forward

• Jal Shakti Abhiyan has helped revive 1.5 lakh water bodies since 2019, but community engagement remains low. Women, who often fetch water, should be central to water governance and planning.
• Integrated Water Resources Management (IWRM) that is blending traditional methods, nature-based solutions, and technology is key to sustainable management.
• Policies must align across sectors water, energy, agriculture, and climate to prevent fragmented efforts. For instance, solar-powered irrigation could address groundwater depletion and reduce carbon emissions simultaneously.

Conclusion

India’s water crisis is not a challenge of capacity but of intent. The tools for building a water-secure and climate-resilient economy already exist. What is required is bold leadership, integrated policymaking, and grassroots-level engagement. Addressing water insecurity is not just an environmental necessity but a national imperative — one that underpins our agricultural sustainability, urban future, public health, and economic growth. With 1.4 billion lives at stake, delay is no longer an option.
