  • Counting rural women’s labour

    What’s the news?

    • In a concerning revelation, India grapples with one of the world’s lowest female labor force participation rates, while rural women face widening gender wage gaps and continue to make substantial, often unpaid, contributions to the economy.

    Central idea

    • As the International Day of Rural Women approaches, it is essential to shed light on the grim reality that India is grappling with. India not only records one of the lowest female labor force participation rates (LFPR) globally, but also ranks lower than most South Asian nations, trailing only Afghanistan and Pakistan.

    Rural Women’s Employment Landscape

    • India has one of the lowest female LFPRs globally. The LFPR for women in the working-age group (15–59 years) is just 35.6 percent, and this figure varies significantly between rural and urban areas.
    • In rural regions, the LFPR is comparatively higher at 39.3 percent, while in urban areas, it is much lower at 26.5 percent, according to the Periodic Labour Force Survey (PLFS) data for 2021–22.
    • Self-Employment and Agriculture:
    • A significant portion of rural women in India are engaged in self-employment, particularly in agriculture and allied activities.
    • Nearly three-fourths of rural working women are involved in these sectors, which include crop cultivation, livestock rearing, and related tasks.
    • Agriculture remains a crucial source of livelihood for many rural women.

    Gender Wage Gap in Rural India

    • Higher Gender Wage Gap in Rural Areas: Rural women working as regular and casual wage laborers face a more pronounced gender wage gap compared to their urban counterparts. This wage disparity is particularly significant in the rural employment sector.

    • PMKVY (Pradhan Mantri Kaushal Vikas Yojana): PMKVY focuses on skill development for rural youth, including women, to enhance employability. It offers training programs in various sectors to equip them with the necessary skills for job opportunities.
    • Beti Bachao, Beti Padhao: This campaign encourages the education and welfare of girls in rural areas, indirectly empowering rural women by reducing gender disparities and promoting education among girls.
    • National Rural Livelihood Mission (NRLM): NRLM aims to reduce poverty among rural women by promoting self-employment and entrepreneurship. It provides training, financial support, and market access, empowering women to start and run their own businesses.
    • Support for Training and Employment Programs for Women (STEP): STEP is another initiative focused on skill development and employment for disadvantaged women in rural areas. It offers training in various trades to enhance their employability.

    Addressing the issue of unpaid labor in rural India requires a multi-faceted approach

    • Recognition: There is a need to recognize and value the significant contributions of rural women to unpaid domestic chores and agriculture. Acknowledging this work is crucial for appreciating its economic and societal importance.
    • Gender Equity: Promoting gender equity in domestic and caregiving responsibilities is essential to reducing the burden on rural women. Encouraging men to share these responsibilities can free up women’s time for productive activities.
    • Economic Empowerment: Empowering rural women through education, skill development, and access to income-generating opportunities can help them transition from unpaid to paid work, improving their economic status.
    • Policy Support: Government policies should be designed to address the gender disparities in unpaid labor and provide support mechanisms, such as access to affordable childcare and elderly care facilities, to reduce the time spent on unpaid caregiving.

    Conclusion

    • The contributions of rural women in India, whether unpaid, unaccounted, or underpaid, are the backbone of the country’s rural economy. Only by acknowledging the hidden work of rural women and bridging the gender gap in land ownership and access to support schemes can we truly empower the rural women of India and pave the way for a more equitable future.

  • Uterus Transplants: Procedure, Challenges, and Future Prospects

    Uterus

    Central Idea

    • In the UK, doctors at the Churchill Hospital Oxford conducted the nation’s first uterus transplant.
    • The procedure involved removing a uterus from a 40-year-old woman and transplanting it into her 34-year-old sister, who faced reproductive challenges due to a rare medical condition.

    Why discuss this?

    • While the transplanted womb is functional, its success can only be confirmed by a live birth in the future.

    Understanding Uterus Transplants

    • Not Life-Saving: Unlike heart or liver transplants, uterus transplants are not life-saving procedures. Instead, they are akin to limb or skin transplants, significantly enhancing individuals’ quality of life.
    • Addressing Uterine Infertility: Uterus transplants offer hope to women facing uterine factor infertility, enabling them to fulfill their reproductive aspirations.

    Pioneering Success in Sweden

    • Historical Context: In 2014, Sweden achieved a milestone by witnessing the first live birth following a uterus transplant. This success paved the way for addressing uterine factor infertility.
    • Affordability Challenge: Efforts are ongoing to make uterus transplants more accessible, especially in countries like the UK, where the National Health Service estimates the procedure’s cost at GBP 25,000 (Rs 25.26 lakh).

    Uterus Transplants in India

    • Indian Achievement: India joined the ranks of countries with successful uterus transplants, alongside Turkey, Sweden, and the United States. The country celebrated its first uterine transplant baby’s birth on October 18, 2018, approximately 17 months after the recipient underwent the procedure.
    • Affordable Option: The cost of uterine transplant surgery in India currently ranges from Rs 15-17 lakh, making it a more cost-effective choice for many.

    Step-by-Step Procedure

    • Recipient Evaluation: Before transplantation, recipients undergo thorough evaluations to assess their physical and mental health.
    • Donor Assessment: Whether the donor is living or deceased, their uterus undergoes viability checks before qualifying for donation. Live donors also undergo comprehensive gynecological examinations, including imaging scans and cancer screenings.
    • In Vitro Fertilization (IVF): Uterus transplants do not connect the uterus to the fallopian tubes, necessitating IVF to create embryos. These embryos are then cryopreserved until the transplanted uterus is ready for implantation.
    • Harvesting and Transplantation: The donor’s uterus is carefully removed, with the procedure becoming less invasive due to advancements in robot-assisted laparoscopy. The uterine vasculature and other critical connections are meticulously re-established during transplantation.

    Pregnancy after Transplant

    • The success of the transplant is assessed through three stages: the first three months focus on graft viability, followed by six months to one year for monitoring uterine function.
    • Only after this period can the recipient attempt conception.

    Issues with such transplants

    • Challenges and Risks: Pregnancy after a uterine transplant entails a higher risk of rejection, spontaneous abortion, intrauterine complications, low birth weight, and premature birth. Close monitoring and follow-ups are essential.
    • Immunosuppressant Use: Recipients must take immune-suppressing drugs to prevent rejection of the transplanted uterus. These drugs are selected to ensure they do not harm foetal development but can cause side effects such as kidney toxicity, bone marrow issues, and an increased risk of diabetes and cancer.
    • Long-Term Follow-Ups: Post-uterus removal, recipients are advised to undergo regular follow-ups for at least a decade to monitor potential long-term effects of immunosuppressant drugs.

    Exploring Artificial Uteri

    • Future Possibilities: Successful uterus transplants have opened doors to exploring artificial uteri. These bioengineered organs, grown from stem cells on 3D scaffolds, could eliminate the need for live donors and ethical concerns. However, research is still in its early stages, and it may take about a decade before artificial uteri becomes efficient and safe for human use.
    • Inclusivity Considerations: Artificial uteri could benefit not only women but also members of the LGBTQ+ community. However, certain complications, such as hormone-related considerations for trans-women recipients, remain to be addressed.

    Conclusion

    • Uterus transplants represent a remarkable medical advancement offering hope and possibilities for individuals facing uterine factor infertility.
    • While challenges persist, ongoing research and technological progress continue to expand the horizons of reproductive medicine.

    • Sikkim, nestled in the Himalayas, faces the aftermath of a catastrophic Glacial Lake Outburst Flood (GLOF) triggered by incessant rainfall. The South Lhonak Lake, perched at 17,000 feet in the state’s northwest, burst, inundating four districts—Mangan, Gangtok, Pakyong, and Namchi.

    What are glacial lakes?

    • Glacial lakes are large bodies of water that are typically located in proximity to, on top of, or beneath glaciers.
    • These lakes are primarily formed as a result of glacial processes, such as the melting of ice and the accumulation of meltwater in depressions or basins created by the glacier’s movement.

    Concept: Glacial Lake Outburst Floods (GLOF)

    • A Glacial Lake Outburst Flood (GLOF) is a sudden and often catastrophic release of water from a glacial lake, typically caused by the breach or failure of the natural dams that contain the lake.
    • GLOFs occur in regions with glaciers, where meltwater accumulates in depressions or basins created by the glacier’s movement.
    • These floods can have severe and far-reaching consequences for downstream communities and environments.

    Causes: GLOFs can be triggered by various factors

    • Melting Glaciers: Rapid glacier melt due to rising temperatures can increase the volume of water in glacial lakes.
    • Avalanches: Snow or ice avalanches can impact the lake, dislodging ice and debris into the water.
    • Earthquakes: Seismic activity can destabilize the natural dams or trigger avalanches.
    • Rainfall: Heavy rainfall can contribute additional water to the lake and weaken natural dams.
    • Volcanic Eruptions: Volcanic activity can lead to the rapid melting of glaciers and the formation of glacial lakes.

    Destruction and Impact

    • Flooding: Downstream areas can experience rapid and extensive flooding, with water levels rising quickly.
    • Destruction of Infrastructure: GLOFs can damage or destroy roads, bridges, buildings, and farmland.
    • Loss of Life: GLOFs often result in the loss of human lives as well as harm to livestock and wildlife.
    • Environmental Damage: The floodwaters and debris can severely impact the natural environment, including forests, wetlands, and river ecosystems.

    Notable GLOF events

    • Some GLOF events in the past have resulted in significant loss of life and damage to infrastructure.
    • The horrifying 2013 flash floods in Uttarakhand’s Kedarnath serve as a stark reminder of the devastating consequences of GLOFs.
    • This calamity was compounded by a GLOF event originating from the Chorabari Tal glacial lake, leading to the loss of thousands of lives.

    The Sikkim Calamity: South Lhonak Lake’s Susceptibility to GLOF

    • Glacial Melting: Rising global temperatures have accelerated the melting of glaciers in the Sikkim Himalayas, including the glacier feeding South Lhonak Lake. This increased meltwater contributes to the lake’s water volume, making it more susceptible to GLOFs.
    • Glacial Lake Expansion: The South Lhonak Lake’s area has significantly increased over the past five decades. It has grown nearly 1.5 times, while its neighbor, North Lhonak, has expanded nearly 2.5 times its initial size in 1989. This expansion is a direct result of glacier retreat and melt, exacerbating the lake’s vulnerability.
    • Seismic Activity: The region around South Lhonak Lake is prone to seismic activity. Earthquakes can destabilize the natural dams or trigger avalanches, which can lead to a sudden release of water from the lake, potentially causing a GLOF event.
    • Past Earthquakes: Seismic events occurred in the region, such as an earthquake of magnitude 4.9 in 1991 near the parent glacier feeding South Lhonak Lake and another earthquake of magnitude 6.9 in 2011, approximately 70 km from the lakes. These past earthquakes and the potential for future seismic activity increase the risk of GLOFs in the area.

    Government interventions

    • Syphoning Off Lake Water: In 2016, the Sikkim government, in collaboration with various agencies including the Sikkim State Disaster Management Authority and Sikkim’s Department of Science and Technology and Climate Change, took proactive measures to mitigate the risk associated with South Lhonak Lake. They decided to syphon off water from the lake.
    • Innovative Approach: The technique employed for syphoning off lake water was innovative and effective. Under the supervision of innovator Sonam Wangchuk, authorities installed three eight-inch-wide and 130-140-meter-long High-Density Polyethylene (HDPE) pipes in the lake. These pipes were used to extract water from the lake.
    • Water Extraction Rate: The initiative successfully extracted 150 liters of water per second from South Lhonak Lake, which was a substantial volume. This action aimed to reduce the water level in the lake, thus mitigating the risk of a potential GLOF.

    Way forward: Warning and Mitigation

    • Lake Monitoring: Regular monitoring of glacial lakes to assess changes in water levels and the stability of natural dams
    • Early Warning Systems: Implementing systems to detect and warn downstream communities of potential GLOFs
    • Infrastructure: constructing protective infrastructure, such as dams or diversion channels, to manage floodwaters
    • Land-Use Planning: Implementing land-use planning and zoning to restrict construction in high-risk areas

    Conclusion

    • The recent calamity in Sikkim underscores the imminent threat of GLOFs in the Himalayan region. While government initiatives are commendable, continued monitoring, research, and disaster preparedness are vital to safeguarding vulnerable communities in the face of the expanding glacial lakes and the looming specter of GLOFs.
