Notes:
Under the Swachh Bharat Mission-Urban, Ghaziabad issued India’s first Certified Green Municipal Bond, raising ₹150 crore for a Tertiary Sewage Treatment Plant (TSTP). This bond marks a major shift towards sustainable urban infrastructure and financial innovation. The Tertiary Sewage Treatment Plant uses advanced Membrane Filtration Technologies like microfiltration, ultrafiltration, nanofiltration, and reverse osmosis (RO) to treat wastewater. The plant has a treatment capacity of 40 Million Litres per Day (MLD) and is linked to a 95 km pipeline network. It supplies treated water to over 1,400 industrial units, cutting dependence on freshwater sources.

Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, have found a new way to improve green hydrogen production. They created a special heterostructure using Copper Tungsten Oxide and Copper Oxide. This structure uses the Built-In Electric Field (BIEF) effect to boost the Hydrogen Evolution Reaction (HER). The Copper Tungsten Oxide nanoparticles are grown over a Cu(OH)₂ base, forming a p-n heterojunction with an uneven electronic setup. This BIEF helps in better proton adsorption and desorption. Green hydrogen, made from water using clean energy, is a pollution-free fuel of the future.

Notes:
A six-year-old girl in Kerala’s Malappuram district sadly died of rabies even after getting preventive vaccination, highlighting a serious public health concern. Rabies is a fatal zoonotic disease caused by the Rabies virus (RABV), which attacks the nervous system. Rabies virus is an RNA virus from the rhabdovirus family and spreads in two main ways in the body. It can directly enter the peripheral nervous system and reach the brain.

Notes:
Rajasthan has joined India’s first inter-state cheetah conservation corridor with Madhya Pradesh. This wildlife corridor is designed to connect protected areas in both states, allowing reintroduced cheetahs to roam safely across a vast ecosystem. The corridor covers 17,000 square kilometers, with 10,500 square kilometers in Madhya Pradesh and 6,500 square kilometers in Rajasthan. Key locations include Palpur Kuno National Park and Gandhi Sagar Sanctuary in Madhya Pradesh, which will serve as cheetah habitats. Mukundara Hills Tiger Reserve in Rajasthan, along with several districts like Kota and Sawai Madhopur, has been identified as a cheetah habitat.

Notes:
Union Minister of Information and Broadcasting Ashwini Vaishnaw launched the Indian Institute of Creative Technology (IICT) in Mumbai during the WAVES 2025 event. IICT is a national-level institute focused on Animation, Visual Effects, Gaming, and Comics (AVGC). It has already started functioning from the National Film Development Corporation (NFDC) building on Pedder Road, Mumbai. It is established by the Ministry of Information and Broadcasting with support from FICCI (Federation of Indian Chambers of Commerce and Industry) and CII (Confederation of Indian Industry).

Notes:
Reliance NU Suntech recently signed a 25-year Power Purchase Agreement with the Solar Energy Corporation of India Limited (SECI) to build Asia’s largest single-location integrated solar and Battery Energy Storage System (BESS) project. SECI is a Central Public Sector Undertaking (CPSU) under the Ministry of New and Renewable Energy (MNRE), dedicated to expanding Renewable Energy (RE) in India. SECI was formed in 2011 as a not-for-profit company and later became a commercial entity in 2015. It was established to support the National Solar Mission and has Miniratna Category-I status. SECI acts as the main agency for implementing solar, wind, and hybrid energy projects across India. It also helps fulfill India’s Nationally Determined Contributions (NDCs) by inviting developers through tenders for RE projects.

A recent report by the Wildlife Justice Commission (WJC) says global trafficking of pangolin scales has dropped sharply since 2020 due to COVID-19 disruptions, strong law enforcement, and changing smuggling methods. Pangolins are insect-eating mammals found in tropical forests, grasslands, and farms, often near people. There are 8 species of pangolins — 4 in Africa and 4 in Asia, including the Indian pangolin found in India, Nepal, Sri Lanka, and Bangladesh. They eat ants and termites, helping control pests and improve soil, which supports healthy ecosystems. Pangolins are hunted for their meat and scales used in traditional medicine. The Indian pangolin is listed as Endangered and the Chinese pangolin as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.

Notes:
India’s SVAMITVA scheme will be highlighted at the World Bank Land Conference in Washington, D.C., showcasing its role in digitalising rural land records. SVAMITVA stands for Survey of Villages and Mapping with Improvised Technology in Village Areas and was launched in 2020 as a central sector scheme. It aims to give rural residents legal documents for their residential properties to help them access loans and other financial services. Drone technology is used to survey land parcels in rural inhabited areas across India in phases. The scheme helps bring financial stability to rural citizens by treating property as a financial asset. It also ensures accurate land records for better rural planning and governance. The Ministry of Panchayati Raj (MoPR) is the nodal ministry for implementing the scheme. State Revenue or Land Records Departments implement the scheme with support from State Panchayati Raj Departments.
