    Study Notes

    Global Water Scarcity and Water Conflicts

    • Water scarcity arises from the growing water demand driven by population growth and economic development.
    • Defined as a condition where the demand for water across all sectors exceeds supply.
    • Areas in middle to low latitudes of the northern hemisphere typically face significant water scarcity.
    • Conflicts over water resources have been a historical global issue, impacting many nations involved in river sharing, like India, Pakistan, and Sudan.

    The Cauvery River Basin

    • The Cauvery River is the fourth longest in South India, stretching 802 km (498.34 mi) and draining an area of 81,155 sq.km.
    • Originates in the Western Ghats and flows into the Bay of Bengal, with major stretches in Karnataka and Tamil Nadu.
    • Receives rainfall from the southwest monsoon (June-September) and northeast monsoon (November-January), influencing agricultural patterns.

    Climate, Soil, and Land Use

    • Rainfall patterns vary significantly; the southwest monsoon is predominant in Karnataka, while Tamil Nadu primarily relies on the northeast monsoon.
    • Principal soil types include black, red, lateritic, and alluvial soils, with agricultural land covering around 66.21% of the basin.
    • Major crops include rice and sugarcane, with varying irrigation methods based on seasonal monsoon patterns.

    Water Availability and Population Dynamics

    • Cauvery flows with a total surface runoff of 21.4 cu km, and potentially utilizable water is about 27.8 cu km.
    • The population in the basin was about 38.76 million as of 2011, with a density of 478 persons per sq.km, and about 70% are rural.
    • Per capita water availability indicates chronic scarcity, with 676 CuM of renewable surface water available.

    Major Water Use

    • The Cauvery River serves crucial agricultural needs, especially rice production, deeply intertwining socio-economic factors.
    • Urban demands, particularly from Bangalore, significantly strain the river's resources, with a population surge impacting availability.

    Conflict Timeline (Pre- and Post-Independence)

    • Pre-independence conflicts (19th century) initiated due to irrigation projects between the Mysore state (now Karnataka) and Madras presidency (now Tamil Nadu).
    • The 1892 and 1924 agreements aimed to regulate water sharing but faced limitations leading to ongoing disputes.
    • Post-independence, the reorganization of states marked a new phase of contention over resource allocation.

    Federal Trial and Final Verdict

    • Formation of the Cauvery Water Disputes Tribunal (CWDT) in 1990 enhanced legal recognition of the dispute, culminating in a 2007 award that both states contested.
    • Supreme Court's 2018 verdict resulted in Karnataka receiving a larger share (284.75 TMC) compared to Tamil Nadu (404.25 TMC) for the next 15 years.
    • The establishment of the Cauvery Management Authority was mandated to implement the court's decision and manage the ongoing dispute effectively.
