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.

हर घर जल: चुनौतियाँ और अवसर

Dr Syamal Kumar Sarkar
Dr Shresth Tayal

पेयजल आपूर्ति में भारत का अनुभव नया नहीं है। जल जीवन मिशन कार्यक्रम से पहले, ग्रामीण घरों में पेयजल आपूर्ति प्रणाली के प्रावधान में एक बड़ी राशि खर्च की गई थी। 'जल जीवन मिशन' के लिए वित्त वर्ष 2020-21 के बजट में 11,500 करोड़ रुपये रुपए आवंटित किए हैं। इस कार्यक्रम को एक बड़ी सफलता बनाने के लिए कुछ महत्वपूर्ण मुद्दों को जल्द हल किया जाना चाहिए।

पटियाला और लुधियाना के कूड़े से भरे तालाबों में आई जान : फिर से हुए लबालब

Ms Shweta

सालों पुराने तालाब कूड़े के ढेर में तब्दील हो रहे थे। लेकिन इन सिकुड़ते तालाबों को टेरी और यूबियल ने मिलकर सामुदायिक सहभागिता से पुनर्जीवित किया है। सबकी भागीदारी से ये तालाब अब पानी से लबालब भर गए हैं। घटते भूजल स्तर के लिए एक तालाब का बड़ा महत्व है। इस तरह के प्रयास जारी रहने चाहिए।

पानी की होगी कमी: वर्षा जल संचयन को बनाना होगा एक जन आंदोलन

Dr Syamal Kumar Sarkar

जल संसाधन सीमित और दुर्लभ हैं। पानी घट रहा है और साल 2050 तक यह कमी एक बड़ा संकट बन सकती है। ऐसे में हमें वर्षा जल संचयन जैसे जल संरक्षण के स्थायी तरीकों को अपनाना चाहिए। वर्षा जल संरक्षण न सिर्फ मैदानी बल्कि पहाड़ी इलाकों के लिए भी ज़रूरी है।

गाँवों में पानी के संकट को मिटाएगा जल जीवन मिशन, आसान नहीं है डगर पनघट की

Ms Shweta

अभी ग्रामीण घरों में पाइप से पानी की आपूर्ति लगभग 18% है और जल जीवन मिशन में इसे 100% तक पहुंचाने का लक्ष्य है। पिछले साल प्रधानमंत्री नरेन्द्र मोदी ने स्वतंत्रता दिवस 2019 के अवसर पर देश के सभी घरों को पाइप के द्वारा जल उपलब्ध करवाने के लिए “जल जीवन मिशन” की घोषणा की थी। इसके लिए केंद्र और राज्य मिलकर काम करेंगे। घरों तक नल के माध्यम से जल पहुंचाने की इस महत्त्वाकांक्षी परियोजना पर 3.60 लाख करोड़ रुपये लागत आने का अनुमान है, जिसमें केंद्र सरकार 2.08 लाख करोड़ रुपये अंशदान देगी। 'जल जीवन मिशन' के लिए वित्त वर्ष 2020-21 के बजट में 11,500 करोड़ रुपये रुपए आवंटित किए हैं।

Water management in the hills needs a serious rethink

The available water resources in the hills should not be taken for granted and the urgency of caution with regard to the exploitation of water – a critical resource – must not be underplayed.

Are we at sea on marine plastic pollution?

November 11, 2020

| Mr Kaushik Chandrasekhar
| The Financial Express

India is considered the twelfth-largest source of marine litter and is projected to become the fifth-largest by 2025. The Ganga has been documented as one of the top-five rivers dumping plastics into oceans. India, as per 2017-18 estimates, consumes 16.5 mt of plastic annually, 43% of which was towards the manufacture of single-use plastic material. The Covid-19 outbreak has exacerbated this situation, with the pandemic demanding the use of personal protective equipment (PPE) such as suits, masks and gloves that are often discarded in unscientific ways.

One of the world's toughest lockdowns against the coronavirus, which has caused nearly 217,000 infections and more than 6,000 deaths in India, kept out most of the industrial waste that normally clogs the Yamuna. That was the key reason for the better water quality, said Mr Anshuman Jaiswal, TERI.

Need To Conserve Biodiversity By Conserving Water Resources

| Smart Water & Waste World

Biodiversity and water resources are intrinsically linked. Biodiversity supports water resources including nutrient cycling in soil and plants. This process controls water quality. Similarly, water resources supports biodiversity: without sufficient water there is stress on species thereby causing biodiversity loss. Conserving biodiversity helps waterways against nitrogen pollution. In fact, streams with more species help in removing excess nutrients in water.

The launching of a novel scheme under the Jal Jeevan Mission (JJM) by the Prime Minister in December for ensuring piped water supply to all rural households by 2024, is a welcome step in meeting the UN's Sustainable Development Goals (6.1) for achieving universal and equitable access to safe and affordable drinking water for all by 2030. While the scheme has many important features, there are many challenges before the policymakers and its implementers.

No More Dry Days! Why the Next Delhi Government Must Prioritise 24/7 Water Supply

February 10, 2020
| Ms Sonia Grover
| News 18

Water has been at the core of political agenda to lure voters. Subsidising bills and tariffs may increase the vote bank, but it results in the misuse of a finite resource. Highly subsidised tariffs, if clubbed with a 24/7 water supply scheme, will lead us into a dark zone. Instead of providing some units of free water, there should be a consumption-based pricing mechanism. Such a mechanism, along with round-the-clock supply scheme, can help in creating awareness about the value of water among consumers and help in recovering the cost of the system, thus making it a sustainable solution.

Climate change impacts on Himalayan glaciers and implications on energy security of India

November 8, 2019

Climate change has a strong influence on the precipitation over the Himalayas as well as melting response of glaciers or snow cover in Himalayas. This, in turn, affects the runoff pattern of rivers draining from the glaciated catchments of Himalayas. Three major river catchments along with their several tributaries originating from Indian as well as Nepal part of Himalayas receive a significant contribution from the Himalayan cryosphere, especially during the non-rainfall lean period of the year.

Critical policy interventions to fast forward micro irrigation in India

These workshops identified the key needs and shortlisted the key areas of interventions as expressed by the stakeholders.

Aligning India's water resource policies with the SDGs

November 6, 2018

The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet, now and into the future. At its heart are the 17 Sustainable Development Goals (SDGs), which are an urgent call for action by all countries. The SDGs recognize that ending poverty and other deprivations must go hand-in-hand with strategies that improve health and education, reduce inequality, and spur economic growth – all while tackling climate change.


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.
