World Water Day: Water for Peace
Question : What are the main reasons for water scarcity in different regions of India, and how do they affect local communities?
Water Crisis in India
- Shift from clean, abundant water to scarcity.
- Water stress due to quantity and quality issues.
- Factors: rapid urbanization, industrialization, unsustainable agriculture, climate change, pollution, poor management.
- Impact: ecosystem damage, food insecurity, potential for conflict.
Water Availability
- India already water stressed (below 1500 m3 per capita per year).
- Projected to decrease further (1341 m3 by 2025, 1140 m3 by 2050).
- Water use: 72% agriculture, 16% municipalities, 12% industries.
- Depleting groundwater tables in most states and major cities (e.g., Bengaluru).
- Alarming over-consumption in Punjab, Rajasthan, Delhi, Haryana.
Reasons for Water Scarcity
- Drying springs in hilly areas.
- Silting of reservoirs, water bodies, wetlands due to poor maintenance.
- Unsustainable groundwater withdrawal exceeding recharge.
- Water pollution from sewage and greywater.
- Lack of proper surface and groundwater management.
The Importance of Water
- Water is more than a basic human right, it’s crucial for peace and quality of life.
- Sustainable agriculture, water security, and environmental health depend on water management.
Rainwater Harvesting as a Solution
- Enhances water quantity and quality (blue and green water).
- Builds resilience against water scarcity and drought.
- Augments recharge and aids irrigation.
- Rooftop rainwater harvesting and large-scale structures are essential.
- Conjunctive use of surface and groundwater and wastewater reuse are crucial.
Government Initiatives
- Focus on water conservation and rainwater harvesting.
- Rejuvenation of water bodies, tanks, and wetlands.
- Borewell recharge and development of recharge structures.
- Watershed development and afforestation programs (e.g., Jal Shakti Abhiyan).
Conclusion
- By implementing these solutions, India can achieve water security and contribute to a more peaceful world.
Nuclear Energy: Powering a Clean Future, but Funding Stalled
Nuclear – A Key Player in Climate Action
- UN Climate Change Conference (COP28) recognizes nuclear’s role in decarbonization.
- Nuclear Energy Summit promotes nuclear as part of the clean energy mix.
- Lower carbon emissions than solar or wind.
- Reliable, uninterrupted energy with a smaller land footprint than other renewables.
- Lower operating costs and longer lifespan compared to other renewables.
The Financing Challenge
- Technology advancements like Small Modular Reactors (SMRs) improve safety.
- Destigmatization: Tech startups are entering the nuclear industry.
- However, Multilateral Development Banks (MDBs) and private investors haven’t significantly invested.
India’s Nuclear Power
- Existing plants offer competitive electricity rates (e.g., Tarapur).
- Low contribution (1.6%) to India’s renewable energy mix.
- Limited adoption due to stigma, safety concerns, regulations, and high upfront costs.
A Path Forward for Nuclear Energy
- Positive signs:
- $26 billion sought in private investment for nuclear in India.
- Plans to triple nuclear capacity by 2031-2032.
- Prime Minister Modi’s support for nuclear development.
Challenges to Address
- Secure financing to bridge the gap and make nuclear energy a viable option.
- Address public concerns about safety, proliferation risks, and waste management.
- Streamline regulations to expedite project timelines and reduce costs.
