वर्षाजल संचयन बारिश के पानी के प्राकृतिक तालाब या टंकियों में संग्रहण और भंडारण की एक तकनीक है, साथ ही इसके जरिये भूमिगत जलवाही स्तरों का भी पुनर्भरण किया जाता है (इससे पहले कि यह सतह से सूक जाये). रूफटॉप हारवेस्टिंग वर्षाजल संचयन का एक तरीका है. रूफटॉप हारवेस्टिंग में टाइल, धातु या प्लास्टिक की छत उपयोगी हो सकती है, मगर घास या खजूर या फूस की छत नहीं. यह बारिश के बहाव को रोक देता है और घरेलू इस्तेमाल के लिए उच्च गुणवत्ता वाला पेयजल उपलब्ध कराता है और इसे साल भर के लिए भंडारित किया जा सकता है. इस पानी के दूसरे इस्तेमाल भी हो सकते हैं, जैसे बगीचे के लिए, पालतू पशुओं के लिए, सिंचाई के लिए, आदि.
वर्षाजल संचयन के उपयोग के कारण इन तीन सवालों पर आधारित हैं:
What: क्या : वर्षाजल संचयन से जलापूर्ति और फसल उत्पादन बेहतर होगा और अंततः खाद्य सुरक्षा असरदार होगी.
Who: क्यों : ग्रामीण इलाकों में जल संकट वाले मकान या परिवार वर्षाजल संचयन के इस तंत्र से सर्वाधिक लाभान्वित होंगे.
How: कैसे : चुकि वर्षाजल संचयन जलापूर्ति को बढ़ावा देता है और यह हमें खाद्य सुरक्षा की तरफ ले जाता है, यह जीविकोपार्जन की दिशा में भी बड़ी भागीदारी सुनिश्चित करता है.

Example rainwater harvesting in India
Tamil Nadu is the first Indian state to make rainwater harvesting mandatory. On 30 May 2014, the state government announced that it will set up 50,000 rainwater harvesting structures at various parts of the capital city of Chennai. [1]
Around 4,000 temples in Tamilnadu state traditionally had water tanks that were used for various rituals. The tanks also served as natural aquifers and helped recharge groundwater. Over the years, however, many of these tanks have gone out of use. Overflowing mounds of silt and garbage have replaced the water in them.
Now, following sustained campaigns by voluntary organisations and departments in charge of water distribution and use, authorities in Chennai have decided to restore around 40 major temple tanks in the city. The aim is to convert the tanks into catchments for rainwater harvesting. [2]

Organizations & groups
- Rainwater harvesting sources. A list of 45 NGOs, government organizations, and some private companies that focus on rainwater harvesting programs, policies, and supplies.
- Rainwater for Food Security: We set an enabling environment for rainwater harvesting (RWH), in order to significantly increase food security. With help of our community on Rainwater Harvesting, we support the development of a more unified global network of national and regional organisations, networks and professionals, working in or interested in rainwater harvesting. By bringing together these key-actors and sharing knowledge in multiple ways, the Rainwater for Food Security programme aims to achieve sustainable change in rainwater harvesting programmes.

Community Exchange - Rainwater Harvesting
The image below is the entry to conversations about rainwater harvesting (RWH) including best practices, troubleshooting, and advice about tanks and systems. We sourced these from the Rainwater Harvesting Community - a sub community within the Rural Water Supply Network community on Dgroups - which is a free member-only forum, where people can ask a pool of over 700 members from 86 countries about rainwater harvesting. You can become a member on their site for greater involvement, if you have questions you need to know for your RWH project. Click on the image to get started! Or click here.

RAIN is an international network with the aim to increase access to water for vulnerable sections of society in developing countries - women and children in particular - by collecting and storing rainwater.
Started in December 2003, RAIN focuses on field implementation of small-scale rainwater harvesting projects, capacity building of local organisations and knowledge exchange on rainwater harvesting on a global scale.
