As India heads towards an ever deepening water crisis, we seek to create efficient solutions for managing water resources. These include various initiatives to promote water conservation on the one hand, and on the other, to improve water use efficiency in industrial, domestic and agriculture sectors. To achieve our goal of ensuring long term sustainability of water resources, we focus keenly on policy interventions as well as developing the knowledge and capabilities of all our stakeholders.

Microplastics in the Ganga River - How Dangerous is the Situation?

Microplastics in the Ganga River - How Dangerous is the Situation?

Microplastics are recognized as a main source of marine pollution. The plastic products and waste materials dumped in the Ganga River break down and are eventually broken down into micro particles and the river finally transports large quantities downstream into the ocean.

गुरुग्राम के सिकुड़ते तालाबों के लिए बहुआयामी दृष्टिकोण ज़रूरी

Ms Shweta

2025 तक गुरुग्राम की पानी की आवश्यकता 874.3 मिलियन लीटर प्रतिदिन तक पहुंच सकती है और ये आवश्यकता 2007 की तुलना में लगभग तीन गुना अधिक है। पानी की ज़रूरत बढ़ेगी लेकिन साथ ही खबर ये भी है कि इस शहर के जल निकाय खतरनाक स्तर पर सिकुड़ रहे हैं। इसके कारण कई हैं, जैसे - बिल्डरों के अतिक्रमण, सीवेज की डंपिंग, गाद और निर्माण कचरा और इसकी वजह से 55.2 (2007 में) किमी2 से 2025 तक जल निकाय 0.42 किमी2 तक सिकुड़ने का अनुमान है।

देश में पानी की कमी को हल करने के लिए जल संरक्षण की पारंपरिक समझ को आधुनिक तकनीकी विकास और क्षमता के साथ मिलाने की ज़रूरत है। ‘एयर टू वाटर’ तकनीक दूरदराज और साथ ही दूषित पानी की समस्या झेल रहे क्षेत्रों के लिए पानी की आपूर्ति के अवसर देती है।

पानी की बचत और संरक्षण की दिशा में चार अहम कदम

Dr Syamal Kumar Sarkar
जल संरक्षण के प्रयास या वर्षा जल संचयन के प्रयास स्थानीय स्तर पर होने चाहिए और स्थानीय प्रयासों के बिना जल संरक्षण के प्रयास व्यापक अभियान का रूप नहीं ले सकेंगें पानी के पुनर्चक्रण और पुन: उपयोग को अपनाया जाना चाहिए। ट्रीटमेंट के तरीकों में प्राकृतिक उपचार प्रणाली को शामिल किया जाना चाहिए गैर सरकारी संगठनों, स्थानीय निकायों और व्यक्तियों को स्थानीय पंचायतों के साथ गहनता से जल संरक्षण के काम में शामिल किया जाना चाहिए जल प्रबंधकों और नीति निर्माताओं को जल प्रबंधन प्रशिक्षण दिया जाना

Decentralised waste water treatment systems to improve water security

January 23, 2023

| Mongabay

The decentralised wastewater treatment systems (DEWATS) approach is considered a cost-effective method of wastewater treatment in rural and semi-urban India. DEWATS in India face challenges over a time, as they are unable to meet the effluent standards. The lack of community participation and the delay in adoption of technology-specific regulations for maintenance are some of the challenges. According to the authors Mr.

Joshimath: Why cracks have started coming in the houses, the road is also bursting, know what the experts are telling the reason

Navbharat Times

Why is Joshimath cracking? Why did this situation happen in Joshi Math without any earthquake or natural calamity? Dr. Shrestha Tayal, Senior Ecologist, TERI University, responded to the questions. The Himalayan mountain ranges in Uttarakhand are called very young mountains, and these are fragile hills based on their basic structure. This is why many landslides happen here every year, says Dr. Tayal.

Need for integrated water and climate agenda

There is a need for India to undertake planned efforts to address climate change mitigation and adaptation. Improving water-use efficiency, strengthening early water-warning systems with precision for flood forecast, adopting climate-proofing of cities and resilience measures, increasing groundwater storage, well-managed effluents and other wastewater should be initiated as major steps. Groundwater has to be used in a sustainable way, writes Dr Syamal Kumar Sarkar, Distinguished Fellow & Senior Director, Water Resources Division, TERI.

Water resources are critical for life, and are also essential for economic development. These resources are, however, depleting at a faster rate, resulting in water stress and its scarcity in coming years. There is a need for stringent policy initiatives for long-term and sustainable solutions to conserve water. To ensure better water security in the country, local bodies must implement an integrated water management plan at the local level.

| Moneycontrol

The Millennium City is developing its way into a severe water crisis. There is a need to ramp up water infrastructure such as water meters, pipelines, treatment plant capacities, to meet the demands of rising population. An immediate intervention for restoring the dying water bodies such as lakes, ponds, bundhs, etc. should be done.

Multidisciplinary research on natural resource conservation

We conduct water audits and quality testing that typically include: Estimation of building water use; recommendations of water saving fixtures; estimation of landscape water demand based on input on the soft areas, plant species factors, and the climatic factors; estimation of rainwater harvesting potential and recommendations on the reuse and recycling of treated waste water and rainwater, and appropriate waste-water management schemes and systems.
