Nano Steps towards Climate Smart Agriculture
TerraGreen|May 2023
Nanotechnology may work at a small scale, but the minuscule size of nanomaterials belies their efficiency. Its deceptively small size is no measure of its impact. Little wonder then that the technology is being increasingly applied in agriculture to enhance efficacy and, importantly, to shrink the adverse impact of conventional chemical fertilizers on the environment and health. The TERI-Deakin Nanobiotechnology Centre has been working to evolve ways of effectively using nanobiotechnology to provide sustainable agriculture solutions. In this ‘In Conversation’ section, Dr Pushplata Singh, Senior Fellow, Centre of Excellence in Agri-nanotechnology, TERI, talks to Palak Khanna from the Communications Team, TERI, about the incisive role the technology can play in the fields of agriculture and beyond.

Nano Steps towards Climate Smart Agriculture

What is nanotechnology and what is the principle on which it works? 

Nanotechnology, as the name suggests, works at the nanoscale. The difference between a metre and a nanometre is 109. When the size of a material is reduced by such magnitude, there is a huge change at the surface-chemistry level, and the surface area-to-volume ratio increases significantly. The material becomes highly reactive when there is a gain in surface area over the volume. There are two important impacts of it; they become highly reactive and when used as crop macro or micronutrients, it increases the fertilizer uptake efficiency in plants by several folds. The other aspect is that their frequency of interaction with all biological surfaces increases, which influences safety to human health and the environment.

What are the nanotechnologies developed by TERI to help farmers with climate-smart farming techniques?

In TERI, we develop nanomaterials using a biogenic approach. Microbial organisms are tuned as bio-factories for converting bulk material into nanomaterials, which generally make all nanomaterials produced by TERI safe by design for human health and the environment. We are developing nanomaterials primarily for use in agriculture in the form of nano-fertilizers, nano-pesticides, and smart carriers. At the commercial level, TERI aims to launch some of the nanofertilizers in the second and the third quarter of the ongoing fiscal year 2023–24, and it will include nano-urea, nano-di-ammonium phosphate, and nano-phosphorus. At the research level, TERI is working towards fertilizers including nanoNPK, nano-sulphur, nanocomposite of zinc and iron, nano-boron, multiple nano-micronutrients; nano-pesticides including nano-copper and nano-sulphur; and nano-2,4 D as a weedicide.

Empowering Tomorrow's Workforce The Rise of Vocational Education in India

The young population in India presents both opportunities and challenges, as the workforce needs practical skills that conventional education often lacks. Vocational education and training VET) is essential to provide job-specific expertise, bridging the gap between academic knowledge and industry demands. In this article, Amarpreet Kaur and Vidhi Rani highlight that vocational education and training serve as a cornerstone in India’s efforts to propel economic growth and empower its burgeoning workforce. Vocational education and training are a fundamental component of modern education systems, addressing a pressing need in society. The alignment of VET with the G20 objectives emphasizes its crucial role in inclusive growth, employment, and human capital development.

Water Sustainability Flexible approaches for managing and conserving water resources

In this article, Vijeta Thakur and Dr S K Bhardwaj discuss innovative technologies for water conservation along with urban water management solutions. They also explore policy and governance approaches regarding water conservation. Implementing Integrated Water Resource Management IWRM) helps coordinate the management of water resources across different sectors and stakeholders, balancing competing demands and ensuring sustainable use. Developing transparent and equitable water allocation systems, coupled with appropriate pricing mechanisms that reflect the true value of water, can incentivize conservation and efficient use while ensuring access for all.

The Vanishing Bristled Grassbird

In this article, Dr Surya Prakash tells us about the bristled grassbird, known scientifically as Chaetornis striatus. Endemic to the Indian subcontinent, the bristled grassbird finds itself perilously perched on the brink of endangerment, classified as a‘Vulnerable Species’ by the IUCN since 2010. The relentless decline in its population can be attributed primarily to habitat loss. Keep reading to know more...

Embracing Climate Disclosure Governance India's Banking Sector's Resilient Step

With the introduction of the Disclosure Framework on Climate-related Financial Risks 2024)’ by RBI, it is quite apparent that the banking sector is continuously striving towards sustainability and climate sensitization. The new framework evolves the narrative, acknowledging the inevitability of climate change affecting these entities and, consequently, the broader financial stability. The framework not only acts as a means to inform the various stakeholders about climate-related issues but also to develop a narrative of financial resilience in the face of unprecedented challenges related to climate risks. Naman Mishra and Dr Megha Jain say that the framework is built upon four main pillars—Governance, Strategy, Risk Management, and Metrics Targets. Keep reading to know more...
