It has been practiced in India for thousands of years, particularly in regions with low rainfall and scarce water resources. In recent years, the Indian government has also taken several initiatives to promote rainwater harvesting. These initiatives are run to conserve water and address the water crisis in the country.<\/span><\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-large wp-image-4807\" src=\"https:\/\/harisharandevgan.com\/wp-content\/uploads\/2024\/03\/Rainwater-Harvesting-in-India-\u2013-Methods-Benefits-1-1024x576.webp\" alt=\"Rainwater Harvesting in India \" width=\"1024\" height=\"576\" srcset=\"https:\/\/harisharandevgan.com\/blogs\/wp-content\/uploads\/2024\/03\/Rainwater-Harvesting-in-India-\u2013-Methods-Benefits-1-1024x576.webp 1024w, https:\/\/harisharandevgan.com\/blogs\/wp-content\/uploads\/2024\/03\/Rainwater-Harvesting-in-India-\u2013-Methods-Benefits-1-300x169.webp 300w, https:\/\/harisharandevgan.com\/blogs\/wp-content\/uploads\/2024\/03\/Rainwater-Harvesting-in-India-\u2013-Methods-Benefits-1-768x432.webp 768w, https:\/\/harisharandevgan.com\/blogs\/wp-content\/uploads\/2024\/03\/Rainwater-Harvesting-in-India-\u2013-Methods-Benefits-1-1536x864.webp 1536w, https:\/\/harisharandevgan.com\/blogs\/wp-content\/uploads\/2024\/03\/Rainwater-Harvesting-in-India-\u2013-Methods-Benefits-1-2048x1152.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p><span data-preserver-spaces=\"true\">The Government of India has made it mandatory for all new buildings in urban areas with a plot area of more than 100 sq.m. to have provisions for rainwater harvesting. The government has also launched various schemes and programs to promote rainwater harvesting in rural areas. Read further to know about &#8216;<\/span>Government schemes in the agriculture sector.&#8217;<\/p>\n<p><span data-preserver-spaces=\"true\">Rainwater harvesting can also help to reduce soil erosion and flooding by capturing and storing rainwater that would otherwise cause surface runoff. This helps to recharge groundwater and prevent soil erosion, contributing to land degradation and soil fertility loss. It can also help to maintain the <a href=\"https:\/\/harisharandevgan.com\/blogs\/importance-of-soil-moisture-sensors\/\">soil moisture<\/a> level.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Several states in India have also taken initiatives to promote rainwater harvesting. For example, the Government of Tamil Nadu has implemented the Tamil Nadu Water Supply and Drainage Board Act. That mandates rainwater harvesting structures in buildings with a more than 100 sq.m roof area. In Rajasthan, the government has implemented the Mukhyamantri Jal Swavlamban Abhiyan to promote rainwater harvesting and conservation in the state.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Apart from government initiatives, several non-governmental organizations (NGOs) and individuals have also taken up the cause of rainwater harvesting in India. Some organizations have conducted awareness campaigns, training programs, and workshops to promote rainwater harvesting and educate people on its benefits.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Overall, rainwater harvesting has gained significant momentum in India in recent years.
