India's National Water Policy


The National Water Policy (NWP) is India's central framework for managing and utilizing its water resources. It lays down principles, objectives, and strategies for optimal water development, management, and regulation across the country.

Year of Initiation and Revisions:

  • The first NWP was adopted in 1987, focusing on increasing irrigation, drinking water access, and sanitation facilities.
  • It was revised in 2002 to address emerging challenges like inter-state water disputes and environmental considerations.
  • The current policy, NWP 2012, emphasizes integrated water management, conservation, and sustainability.

Ministry of Jal Shakti:

  • In 2019, the Ministry of Water Resources, River Development and Ganga Rejuvenation was merged with the Ministry of Drinking Water and Sanitation to form the Ministry of Jal Shakti.
  • This unified ministry oversees the implementation of the NWP and other water-related programs and initiatives.

Key Highlights of the NWP 2012:

  • Equity and social justice: Prioritizes equitable water allocation for various uses, including drinking, irrigation, industry, and ecology.
  • Decentralized management: Promotes participatory decision-making through local water user groups and basin-level planning.
  • Water conservation and efficiency: Encourages rainwater harvesting, efficient irrigation practices, and wastewater reuse.
  • Environmental protection: Recognizes the ecological needs of rivers and aquatic ecosystems.
  • Pricing and tariffs: Advocates for volumetric water pricing to promote efficient usage and cost recovery.

Related Information:

  • Jal Jeevan Mission: Aims to provide piped water supply to all rural households by 2024.
  • Catch the Rain campaign: Promotes rainwater harvesting structures across the country.
  • Atal Mission for Rejuvenation and Urban Transformation (AMRUT): Focuses on water supply and sanitation infrastructure in urban areas.
  • National Water Mission: Launched under the National Action Plan on Climate Change, it aims to improve water availability and efficiency through various interventions.

Challenges and Concerns:Implementing the NWP effectively requires coordinated efforts from various stakeholders at central, state, and local levels.

  • Balancing different water demands and ensuring equitable access remains a challenge.
  • Addressing issues like climate change, pollution, and groundwater depletion requires urgent attention.

Types of Remote Sensing

Remote Sensing means collecting information about the Earth's surface without touching it , usually using satellites, aircraft, or drones . There are different types of remote sensing based on the energy source and the wavelength region used. 🛰️ 1. Active Remote Sensing 📘 Concept: In active remote sensing , the sensor sends out its own energy (like a signal or pulse) to the Earth's surface. The sensor then records the reflected or backscattered energy that comes back from the surface. ⚙️ Key Terminology: Transmitter: sends energy (like a radar pulse or laser beam). Receiver: detects the energy that bounces back. Backscatter: energy that is reflected back to the sensor. 📊 Examples of Active Sensors: RADAR (Radio Detection and Ranging): Uses microwave signals to detect surface roughness, soil moisture, or ocean waves. LiDAR (Light Detection and Ranging): Uses laser light (near-infrared) to measure elevation, vegetation...

Energy Interaction with Atmosphere and Earth Surface

In Remote Sensing , satellites record electromagnetic radiation (EMR) that is reflected or emitted from the Earth. Before reaching the sensor, radiation interacts with: The Atmosphere The Earth's Surface These interactions control how satellite images look and how we interpret them. I. Interaction of EMR with the Atmosphere When solar radiation travels from the Sun to the Earth, four main processes occur: 1. Absorption Definition: Absorption occurs when atmospheric gases absorb radiation at specific wavelengths and convert it into heat. Main absorbing gases: Ozone (O₃) → absorbs Ultraviolet (UV) Carbon dioxide (CO₂) → absorbs Thermal Infrared Water vapour (H₂O) → absorbs Infrared Concept: Atmospheric Windows These are wavelength regions where absorption is very low, allowing radiation to pass through the atmosphere. Remote sensing depends on these windows. For example, satellites like Landsat 8 use visible, near-infrared, and thermal bands located in atmospheric windows. 2. Trans...

Platforms in Remote Sensing

In remote sensing, a platform is the physical structure or vehicle that carries a sensor (camera, scanner, radar, etc.) to observe and collect information about the Earth's surface. Platforms are classified mainly by their altitude and mobility : Ground-Based Platforms Definition : Sensors mounted on the Earth's surface or very close to it. Examples : Tripods, towers, ground vehicles, handheld instruments. Applications : Calibration and validation of satellite data Detailed local studies (e.g., soil properties, vegetation health, air quality) Strength : High spatial detail but limited coverage. Airborne Platforms Definition : Sensors carried by aircraft, balloons, or drones (UAVs). Altitude : A few hundred meters to ~20 km. Examples : Airplanes with multispectral scanners UAVs with high-resolution cameras or LiDAR High-altitude balloons (stratospheric platforms) Applications : Local-to-regional mapping ...

Government of Kerala Initiatives for Water Management

Kerala, with its abundant rainfall and network of rivers, faces a dual challenge of water scarcity and excess —seasonal droughts and monsoon floods. The state government has implemented various policies and programs to address these challenges through sustainable water conservation, management, and distribution practices . Below is a detailed breakdown of the major water management initiatives in Kerala. 1. Jal Jeevan Mission (JJM) – Kerala Implementation Objective: To provide functional household tap connections (FHTC) to all rural households by 2024. Focuses on source sustainability and community-led water resource management. Key Features: Water Quality Monitoring & Surveillance: Ensures supply of safe drinking water through real-time monitoring. Decentralized Approach: Implementation through gram panchayats and local self-governments (LSGs) . Recharge & Conservation Measures: Rainwater harvesting, groundwater recharge, and watershed development inte...
