New Delhi, July 29: The Delhi Development Authority (DDA) has launched the first phase of an ecological restoration project to revive 120 hectares of the Delhi Ridge by planting around 1.81 lakh native trees and shrubs while removing invasive plant species. The restoration work is being carried out across the South Central Ridge, Central Ridge, Kamla Nehru Ridge and Nanakpura Ridge. As part of the initiative, about 16,240 invasive trees and shrubs will be removed, while nearly 1 lakh indigenous trees and 81,700 native shrubs will be planted to restore the area's natural ecosystem. The plantation includes native species such as bargad, peepal, neem, sheesham, arjun, jamun, palash, dhau and khejri, along with shrubs like harshringar, karonda, phalsa, nirgundi and curry leaf. The planta...

New Delhi, July 29: The Central government has directed Uttar Pradesh to prepare a time bound roadmap and complete all sewage treatment and pollution control projects on drains feeding into the Yamuna by January 2028 as part of the Yamuna rejuvenation programme. According to an official status report reviewed by the Union Home Minister last month, Ghaziabad and Loni have been identified as key focus areas because polluted drains from these regions significantly contribute to the contamination of the Yamuna in Delhi. While no drain from Uttar Pradesh flows directly into the Yamuna five drains from Ghaziabad and Loni discharge into Delhi Shahdara drain, accounting for around 40–45 per cent of its total flow. A joint survey found that these drains receive wastewater from 286 secondary d...

Jeddah/Riyadh, July 29: Saudi Arabia's mangrove forests are emerging as a key component of the Kingdom environmental conservation strategy, with scientists highlighting their role in carbon storage, biodiversity conservation and coastal protection as the country accelerates restoration efforts under the Saudi Green Initiative. Researchers said mangroves are among the world's most efficient natural carbon sinks, storing large amounts of "blue carbon" in their roots, sediments and surrounding coastal mud. Besides capturing carbon dioxide, the ecosystems provide nursery habitats for fish, crabs, shrimp and other marine life, reduce coastal erosion, stabilize shorelines and connect vital ecosystems such as coral reefs and seagrass beds. Scientists from King Abdullah University of Science...

  July 29: The first formal dialogue on trade and climate under the United Nations Framework Convention on Climate Change (UNFCCC), held during the 64th session of its Subsidiary Bodies (SB64) in Bonn, Germany, revealed broad agreement that trade can support climate action but sharp differences over how that role should be defined and implemented. The discussions marked the first time trade was formally placed on the UN climate agenda, despite developing countries pushing for its inclusion for more than three decades. Delegates agreed that trade is an important tool for achieving climate goals, but disagreed on issues including carbon border measures, technology transfer, green industrialisation and climate equity. A major point of debate was the European Union’s Carbon Borde...

  July 29: A new citizen science initiative is partnering with Buddhist monasteries across the Himalayas to host automated weather stations, helping close critical gaps in climate monitoring across some of the world's least-observed mountain regions. The initiative called High altitude Monasteries for Data Acquisition, Tracking and Awareness (HiM-DATA), is designed to improve long-term weather observations in the Himalayan region, often referred to as the "Third Pole." The region is warming nearly twice as fast as the global average, increasing the risks of glacier melt, floods, droughts and water insecurity. High altitude weather monitoring has long been a challenge because most meteorological stations are located at lower elevations, while those installed in remote mountain...

  July 29: Urban forests can significantly reduce temperatures during extreme heat waves, with broadleaf and mixed forests providing the strongest cooling effect according to a new study by South Korea National Institute of Forest Science. The research, based on continuous monitoring of temperature and humidity across different urban environments in Seoul, found that forests can lower daytime temperatures by up to 1.8 degrees Celsius compared to densely built-up city areas. Among different forest types, broadleaf and mixed forests containing both deciduous and coniferous trees were the most effective, reducing temperatures by 1.5 to 1.8 degrees Celsius. Coniferous forests provided a smaller cooling effect of about 1.2 degrees Celsius. Researchers attributed the cooling to ...

July 28: Engineers in Ireland have demonstrated an innovative way to tackle wind energy waste by transforming decommissioned wind turbine blades into a pedestrian bridge, offering a sustainable alternative to landfill disposal. The bridge located on the Midleton Youghal Greenway in County Cork was installed in January 2022 by the Re Wind Network using two retired LM13.4 blades from Nordex N29 wind turbines. The project was supported by MaREI, Ireland's national research centre for energy, climate and marine research. Wind turbine blades are among the most difficult components of turbines to recycle. Made from fiberglass or carbon-fiber composites bonded with thermoset resins, they are lightweight, durable and weather-resistant but cannot be easily melted down or reshaped like metals ...

  July 28: Researchers from the University of Wisconsin Madison and Argonne National Laboratory have developed a machine learning model that can track atmospheric conditions in near real time, improving predictions of wildfire smoke movement and helping authorities issue faster air quality warnings. The study focuses on the atmospheric boundary layer the lowest part of the atmosphere where smoke, dust and other airborne pollutants mix. The height of this layer changes throughout the day, shrinking to less than 100 metres at night and expanding to around 2,000 metres during warmer daytime conditions. These changes determine whether wildfire smoke remains trapped near the ground or disperses into the atmosphere. Using high resolution data from the U.S. Department of Energy CROC...

July 28: Australia is set to launch AusAlert, a nationwide emergency warning system that uses cell broadcast technology to send instant alerts to every compatible mobile phone in an affected area during disasters such as bushfires, floods and cyclones. While the system significantly improves emergency communication, experts say accessibility and inclusivity remain key challenges. AusAlert sends warning messages directly from mobile phone towers to nearby devices without requiring users to install an app or register a phone number. Unlike SMS alerts, cell broadcast messages are not affected by network congestion, allowing authorities to rapidly reach residents and visitors within a danger zone. Following community testing in June 2026, a nationwide test was conducted on July 27 with t...
