Restoring Balance in the Kochi Sub-Catchment

Water: Reviving the Lifeline

Water lies at the heart of the Kochi sub-catchment. Encroachment, sedimentation, and untreated runoff had reduced water quality and disrupted natural flow patterns.

The restoration project focused on:

• —Rehabilitating degraded riverbanks and wetlands
• —Afforestation and reforestation of degraded individual and communal farmlands
• —Supporting farmers implement soil and water conservation structures
• —Promoting alternative income generating activities

These interventions have led to improved water quality, reduced flooding during peak rains, and more reliable water availability during dry seasons.

Earth: Healing Degraded Landscapes

Soil erosion and land degradation were major contributors to declining productivity in the sub-catchment. The project adopted sustainable land management practices to rebuild soil health and stabilize the landscape.

Key actions included:

• —Reforestation and agroforestry on degraded slopes
• —Contour bunding and terracing to control erosion
• —Restoration of riparian buffer zones
• —Promotion of organic soil enrichment techniques

As a result, soil fertility has improved, erosion has been reduced, and vegetation cover is steadily increasing, creating more resilient ecosystems.

Air: Enhancing Climate and Ecosystem Health

Although often less visible, air quality and microclimate play a crucial role in ecosystem restoration. Loss of vegetation had previously contributed to rising temperatures and reduced carbon sequestration.

The project addressed this by:

• —Planting native tree species to increase green cover
• —Restoring wetlands that act as natural carbon sinks
• —Reducing dust and particulate matter through ground cover restoration

These measures have helped moderate local temperatures, improve air quality, and strengthen the sub-catchment’s resilience to climate change.
