Traditional Water Harvesting, Storage, and Management in Northern India


Northern India has a rich tradition of water harvesting practices designed to adapt to regional climatic conditions and water availability. These methods, rooted in local knowledge and community efforts, focus on capturing and storing rainwater efficiently to combat water scarcity and ensure sustainability.

Key Concepts, Terminologies, and Examples

  1. Rooftop Rainwater Collection

    • Definition: Rainwater is collected from rooftops and directed into underground tanks or surface storage systems.
    • Example: Taankas in Rajasthan, which are cylindrical underground tanks, store rooftop rainwater for household use.

  2. Surface Runoff Collection

    • Definition: Rainwater flowing over slopes or fields is diverted into small ponds or tanks using earthen structures.
    • Example: Naadas (earthen bunds) channel runoff water into small reservoirs for irrigation.

  3. Stepwells (Bawdis)

    • Definition: Deep wells with steps descending to the water table, providing access to groundwater during dry seasons.
    • Example: The Chand Baori in Rajasthan is a famous stepwell showcasing intricate architecture and utility.

  4. Community Ponds (Johads)

    • Definition: Ponds built and maintained by communities to store rainwater for irrigation and drinking.
    • Example: Johads in Alwar, Rajasthan, have helped restore groundwater levels and revive agricultural activities.

  5. Talabs/Bandhis (Reservoirs)

    • Definition: Large water bodies with earthen embankments designed to store rainwater for various uses.
    • Example: Talabs in Uttar Pradesh are used extensively for irrigation during dry spells.

  6. Ahar Pynes (Floodwater Harvesting)

    • Definition: A dual system of floodwater diversion and storage channels designed for irrigation.
    • Example: Predominantly used in Bihar and eastern Uttar Pradesh, floodwaters from rivers are diverted into Ahars (reservoirs) and Pynes (channels).

Regional Variations in Traditional Practices

  1. Rajasthan

    • Climate: Arid and semi-arid.
    • Practices:
      • Taankas: Widely used for rooftop rainwater harvesting.
      • Bawdis: Provide access to groundwater in drought-prone areas.
      • Johads: Built to recharge groundwater and store water.

  2. Uttar Pradesh

    • Climate: Sub-tropical plains with seasonal rainfall.
    • Practices:
      • Talabs: Large reservoirs for irrigation and floodwater storage.
      • Ahar Pynes: Manage seasonal flooding and ensure irrigation.

Benefits of Traditional Water Harvesting Systems

  1. Groundwater Recharge

    • Concept: Percolation of rainwater into the soil raises the water table.
    • Example: Johads in Rajasthan significantly improved groundwater levels.

  2. Sustainable Water Source

    • Concept: These systems provide a reliable supply during dry periods for drinking, agriculture, and livestock.
    • Example: Stepwells (Bawdis) in Gujarat and Rajasthan offered water security during prolonged droughts.

  3. Flood Control

    • Concept: Managing surface runoff reduces the risk of floods in low-lying areas.
    • Example: Ahar Pynes in Bihar manage monsoon floodwaters effectively.

  4. Community Involvement

    • Concept: Collaborative maintenance and construction of water systems strengthen community ties.
    • Example: Johads in Alwar were restored through community participation under water conservation campaigns.

Disaster Management

1. Disaster Risk Analysis → Disaster Risk Reduction → Disaster Management Cycle Disaster Risk Analysis is the first step in managing disasters. It involves assessing potential hazards, identifying vulnerable populations, and estimating possible impacts. Once risks are identified, Disaster Risk Reduction (DRR) strategies come into play. DRR aims to reduce risk and enhance resilience through planning, infrastructure development, and policy enforcement. The Disaster Management Cycle then ensures a structured approach by dividing actions into pre-disaster, during-disaster, and post-disaster phases . Example Connection: Imagine a coastal city prone to cyclones: Risk Analysis identifies low-lying areas and weak infrastructure. Risk Reduction includes building seawalls, enforcing strict building codes, and training residents for emergency situations. The Disaster Management Cycle ensures ongoing preparedness, immediate response during a cyclone, and long-term recovery afterw...

Pre During and Post Disaster

Disaster management is a structured approach aimed at reducing risks, responding effectively, and ensuring a swift recovery from disasters. It consists of three main phases: Pre-Disaster (Mitigation & Preparedness), During Disaster (Response), and Post-Disaster (Recovery). These phases involve various strategies, policies, and actions to protect lives, property, and the environment. Below is a breakdown of each phase with key concepts, terminologies, and examples. 1. Pre-Disaster Phase (Mitigation and Preparedness) Mitigation: This phase focuses on reducing the severity of a disaster by minimizing risks and vulnerabilities. It involves structural and non-structural measures. Hazard Identification: Recognizing potential natural and human-made hazards (e.g., earthquakes, floods, industrial accidents). Risk Assessment: Evaluating the probability and consequences of disasters using GIS, remote sensing, and historical data. Vulnerability Analysis: Identifying areas and p...

Mapping Process

The mapping process involves several systematic steps to transform real-world spatial information into a readable, accurate, and useful representation. Below is a structured explanation of each step in the mapping process, with key concepts, terminologies, and examples. 1. Defining the Purpose of the Map Before creating a map, it is essential to determine its purpose and audience . Different maps serve different objectives, such as navigation, analysis, or communication. Types of Maps Based on Purpose: Thematic Maps: Focus on specific subjects (e.g., climate maps, population density maps). Topographic Maps: Show natural and human-made features (e.g., contour maps, landform maps). Tourist Maps: Highlight attractions, roads, and landmarks for travelers. Cadastral Maps: Used in land ownership and property boundaries. Navigational Maps: Used in GPS systems for wayfinding. Example: A disaster risk map for floods will highlight flood-prone areas, emergency shelters, and ...

Role of Geography in Disaster Management

Geography plays a pivotal role in disaster management by facilitating an understanding of the impact of natural disasters, guiding preparedness efforts, and supporting effective response and recovery. By analyzing geographical features, environmental conditions, and historical data, geography empowers disaster management professionals to identify risks, plan for hazards, respond to emergencies, assess damage, and monitor recovery. Geographic Information Systems (GIS) serve as crucial tools, providing critical spatial data for informed decision-making throughout the disaster management cycle. Key Concepts, Terminologies, and Examples 1. Identifying Risk: Concept: Risk identification involves analyzing geographical areas to understand their susceptibility to specific natural disasters. By studying historical events, topography, climate patterns, and environmental factors, disaster management experts can predict which regions are most vulnerable. Terminologies: Hazard Risk: The pr...
