Introduction
The interlinking of rivers in India aims to connect water-scarce and water-surplus regions, addressing issues of drought, floods, and navigation. While it presents several advantages, it also raises significant concerns that merit critical examination.
Pros of Interlinking Rivers
Improved Water Management
River interlinking can enhance water resource management, reducing scarcity in drought-prone areas. An example is the Ken-Betwa river interlinking project in Madhya Pradesh, which aims to transfer water from the Ken river basin to the Betwa basin, thereby providing irrigation to farmers in water-scarce regions.
Hydroelectric Power
Interlinked rivers can facilitate hydropower generation, contributing to renewable energy sources. The Damanganga-Pinjal river interlinking project is expected to generate approximately 1,775 MW of hydropower, enhancing energy security in Maharashtra and Gujarat.
Agriculture and Navigation
These projects can also significantly boost agricultural productivity by providing irrigation to vast areas. The Godavari-Cauvery river interlinking project aims to irrigate over 35 million hectares, improving crop yields. Additionally, river interlinking can enhance navigability, promoting inland water transportation, as seen with the proposed National Waterway 4, which connects the Godavari and Krishna rivers.
Cons of Interlinking Rivers
Environmental Concerns
River interlinking can lead to ecological disruptions, including biodiversity loss and wetland degradation. The Ken-Betwa project may submerge about 4,000 hectares of forest land, threatening the Panna Tiger Reserve.
Economic and Social Displacement
Such projects require substantial investment, often leading to cost overruns. The Godavari-Cauvery project has an estimated cost exceeding Rs. 60,000 crore (Source: Planning Commission). Moreover, displacement of communities is a serious concern; the Damanganga-Pinjal project could displace approximately 11,000 people, disrupting their livelihoods.
Inter-State Conflicts
Interlinking may exacerbate tensions between states over water allocation. The Ken-Betwa project has faced opposition from Uttar Pradesh due to concerns about equitable water distribution.
Conclusion
The interlinking of rivers presents a multifaceted dilemma. While it offers solutions for improved water management, hydroelectric power generation, and enhanced agriculture and navigation, the associated environmental risks, economic burdens, social displacements, and potential for inter-state conflicts must be carefully evaluated. A balanced approach is essential to ensure that benefits do not come at the cost of ecological and social stability.

Model Answer
Introduction
India possesses immense potential for solar energy, with an estimated availability of 4,000 trillion kWh per year. This renewable energy source is a key element of India’s energy strategy, with a target of generating 100 GW of solar power out of 175 GW of total renewable energy by 2022, as outlined in the Intended Nationally Determined Contributions (INDCs). Currently, India has an installed solar capacity of 43 GW (Source: Ministry of New and Renewable Energy).
Regional Variations
Ideal Regions for Solar Energy
The desert areas of Rajasthan and Kutch in Gujarat are prime locations for solar energy generation due to their barren lands and high insolation levels. These regions receive abundant sunlight throughout the year, making them ideal for large-scale solar projects.
Low Potential Areas
Conversely, the Himalayan and northeastern regions of India have lower potential for solar energy generation. These areas experience challenging terrain and lower insolation levels, which limit the feasibility of solar energy projects.
Moderate Regions
Coastal states, such as Kerala, exhibit moderate solar energy potential. The long monsoon season affects solar generation compared to states in the heartland of India, which generally receive more consistent sunlight.
Rooftop Solar Potential
Urban areas offer significant opportunities for rooftop solar installations. The rooftop solar panel program can substantially contribute to India’s solar energy goals, especially in metropolitan cities where space is limited.
Challenges to Solar Energy Development
Despite the potential, several challenges hinder the solar energy program in India:
Conclusion
The Indian government has initiated several policies to bolster the solar energy market, including the SARAL Index, PM KUSUM, and floating solar plants in Gujarat. With its low carbon footprint, solar energy holds the potential to replace conventional energy sources and help India meet its commitments under the INDCs and the Panchamrit proposals presented at COP 26. Addressing regional variations and challenges will be crucial for harnessing India’s solar energy potential effectively.
