Q5. Invasive aquatic weeds are often symptoms of ecological collapse, not its root cause. Identify the structural drivers behind invasive proliferation in Indian wetlands. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question Invasive weeds are a common and visible wetland problem in India, and this question tests whether you can go beyond surface-level symptoms to explain deeper ecological and governance causes and propose sustainable solutions. Key Demand of the question You must first justify the statement that invasive weeds are mainly an outcome of wetland degradation, and then identify the structural drivers behind their spread in Indian wetlands, followed by a practical way forward. Structure of the Answer Introduction Start with wetlands as ecological infrastructure and how invasive weeds like water hyacinth flourish when wetlands lose natural regulation due to pollution and hydrological disruption. Body Explain briefly how invasive weeds reflect eutrophication, stagnation and biodiversity weakening rather than being the primary cause. Mention key systemic causes such as sewage and nutrient inflows, agricultural runoff, river–wetland disconnection, siltation and weak governance/encroachment. Suggest source control of nutrients, restoring hydrological connectivity, integrated weed management and stronger wetland governance using monitoring and management plans. Conclusion Close with a crisp line that sustainable weed control requires restoring wetland health through hydrology + pollution control + governance, not only periodic weed removal.
Why the question
Invasive weeds are a common and visible wetland problem in India, and this question tests whether you can go beyond surface-level symptoms to explain deeper ecological and governance causes and propose sustainable solutions.

Structure of the Answer
Introduction Start with wetlands as ecological infrastructure and how invasive weeds like water hyacinth flourish when wetlands lose natural regulation due to pollution and hydrological disruption.
• Explain briefly how invasive weeds reflect eutrophication, stagnation and biodiversity weakening rather than being the primary cause.
• Mention key systemic causes such as sewage and nutrient inflows, agricultural runoff, river–wetland disconnection, siltation and weak governance/encroachment.
• Suggest source control of nutrients, restoring hydrological connectivity, integrated weed management and stronger wetland governance using monitoring and management plans.
Conclusion Close with a crisp line that sustainable weed control requires restoring wetland health through hydrology + pollution control + governance, not only periodic weed removal.
