Impact of Dams on Indian Communities and Environment

Local communities do not benefit from dams, only big industrialists, farmers, and rich city dwellers do.
Tribal people affected by displacement due to dams are often overlooked in discussions about their rights.
Medha Patkar, a prominent social worker, initiated the Narmada Bachao movement to protect tribal populations near the Narmada River.
The Sardar Sarovar Dam has led to the displacement of tribal populations and environmental damage.
Dams like the Sardar Sarovar Dam impact cropping patterns, leading to ecological consequences and soil degradation.
The Sabarmati Dam project in Gujarat caused conflicts between urban and rural areas due to water allocation priorities.
Interstate disputes over water resources, like the Kaveri and Krishna Godavari disputes, are common in India.
Dams can lead to floods, soil erosion, and sedimentation, affecting agriculture and causing natural disasters.
Rainwater harvesting, such as rooftop rainwater collection, is a traditional practice in India to conserve water.
Rainwater harvesting systems vary, but they all aim to collect rainwater for various uses, promoting water conservation and sustainability.

Water Harvesting Techniques Across India

Water harvesting should be done first to prevent water from running down the mountains and causing shortages in valleys.
Guls and Kulas are traditional water-saving systems in the Western Himalayas, where rainfall is scarce.
In Bengal, the Hooghly River floods due to excessive rainwater, benefiting farmers in areas like Sundarbans.
Indane channels are used in Rajasthan to redirect floodwater for agricultural purposes.
Khad, Johad, and Tanka are hydraulic structures in Rajasthan for rainwater harvesting.
Rainwater is collected in tanks in Rajasthan and used for various purposes, including drinking and household chores.
Underground tanks in Rajasthan keep water cool and are used until the next rainfall.
Roof-top rainwater harvesting is common in Southern India, like in the village of Masor in Karnataka.
Tamil Nadu mandates roof-top rainwater harvesting, penalizing those who do not comply.
Bamboo drip irrigation systems in Meghalaya have been used for 200 years to efficiently distribute rainwater to fields.

"Bamboo Drip Irrigation: Versatile and Sustainable"

Bamboo can be used to create a drip irrigation system in fields by making holes in the bamboo to allow water to flow drop by drop, ensuring consistent moisture in the fields.
The bamboo drip irrigation system can be manipulated to be placed in various positions, even above trees or across roads or bridges, allowing for versatile irrigation methods.
This system is particularly useful in areas like Meghalaya where perennial springs provide a consistent water source, aiding in irrigation during dry periods.
The text also mentions various dams and water conservation structures in different regions of India, highlighting the importance of water management and conservation practices.
