Frequently Asked Questions
61. What is Water Scarcity, and what are its primary causes as highlighted for the UPSC exam?
Water scarcity refers to the lack of sufficient water resources to meet water demands within a region. It can be physical (absolute shortage) or economic (lack of investment in water infrastructure). Key causes include population growth, urbanization, industrialization, climate change, pollution, and inefficient water use.
Exam Tip
Remember the dual nature of water scarcity: physical and economic. Also, connect the causes to broader trends like climate change and urbanization.
2. What are the key provisions related to Water Scarcity, as relevant for UPSC, and how do they aim to address the issue?
Key provisions related to water scarcity include the National Water Policy, Environment Protection Act 1986, Inter-State River Water Disputes Act 1956, and Article 21 (Right to Life, which includes the right to water). These aim to promote integrated water resource management, protect water resources, and ensure equitable access to water.
Exam Tip
Focus on understanding the purpose of each legal provision and how they collectively contribute to water security.
3. How does economic water scarcity differ from physical water scarcity, and what are the implications for water management strategies?
Physical water scarcity occurs when there is not enough water to meet demands. Economic water scarcity occurs when water resources are available, but there is a lack of investment in infrastructure to make the water accessible to people. This distinction impacts water management strategies, as physical scarcity requires conservation and supply augmentation, while economic scarcity requires investment in infrastructure and governance.
Exam Tip
Understand that economic scarcity can be addressed through policy and investment, while physical scarcity requires more fundamental changes in water use and resource management.
4. What recent developments, as per the concept data, are aimed at mitigating water scarcity in India?
Recent developments include government initiatives to promote water conservation and water harvesting, implementation of water-efficient irrigation techniques in agriculture, and a focus on groundwater recharge and sustainable groundwater management.
Exam Tip
Focus on the practical application of these developments and their potential impact on water availability.
5. What are the major challenges in the effective implementation of water conservation measures to combat water scarcity in India?
Challenges include: lack of awareness among the public, inadequate infrastructure for water harvesting and storage, inefficient irrigation practices, pollution of water bodies, and conflicts over water resources. Effective implementation requires integrated water resource management and community participation.
Exam Tip
Consider the socio-economic factors that contribute to these challenges and how they can be addressed through policy interventions.
6. How can integrated water resource management (IWRM) help in addressing the challenges posed by water scarcity?
Integrated water resource management (IWRM) promotes the coordinated development and management of water, land, and related resources to maximize economic and social welfare equitably without compromising the sustainability of vital ecosystems. It helps in addressing water scarcity by ensuring efficient allocation, promoting conservation, and reducing conflicts over water resources.
Exam Tip
Remember that IWRM is a holistic approach that considers the interconnectedness of water resources and the need for stakeholder participation.
