WHO holds first traditional medicine summit
GS Paper - 3 (Health and Diseases)
The World Health Organization opened its first summit on traditional medicine with the group saying it was seeking to collect evidence and data to allow for the safe use of such treatments. Traditional medicines are a "first port of call for millions of people worldwide", the UN health agency said.
More about the summit
The two-day WHO Traditional Medicine Global Summit takes place alongside a meeting of G20 health ministers in the Indian city of Gandhinagar.
The first global traditional summit, co-hosted by the World Health Organization (WHO) and the Ministry of Ayush.
This summit is designed to foster political commitment and evidence-based action in the field of traditional medicine.
As a vital healthcare source for millions worldwide, traditional medicine will be closely examined and evaluated as a formidable force in addressing health and well-being needs.
With a wide array of engagement groups, working groups, and meetings, this event aims to represent the interests of the Global South countries within the G20 framework.
The theme of "One Earth, One Family, One Future" embodies India's philosophy of Vasudhaiva Kutumbakam.
More about traditional medicine
The UN health agency defines traditional medicine as the knowledge, skills and practices used over time to maintain health and prevent, diagnose and treat physical and mental illness.
But many traditional treatments have no proven scientific value and conservationists say the industry drives a rampant trade in endangered animals -- including tigers, rhinos and pangolins -- threatening the existence of entire species.
Use of homemade remedies soared during the Covid-19 pandemic, including a green herbal drink based on Artemisia that was promoted by Madagascar's president as a cure.
The plant has a proven efficacy in malaria treatment, but its use to combat Covid was widely scorned by many doctors.
In China, traditional medicine has a distinguished history, but top European medical bodies have previously demanded it be subject to the same regulatory oversight as conventional medical methods.
Flashback
Of the WHO's 194 member states, 170 acknowledged their use of traditional and complementary medicine since 2018, but only 124 reported having laws or regulations for the use of herbal medicines -- while only half had a national policy on such methods and medicines.
About 40 percent of approved pharmaceutical products currently in use derive from a "natural product basis", according to the WHO, which cited "landmark drugs" that derive from traditional medicine, including aspirin, drawing on formulations using willow tree bark.

The vegetated canopies for creating green spaces
GS Paper - 3 (Environment)
As Europe battles scorching temperatures this summer and wildfires blaze across the continent from the Mediterranean to Spain, the role of climate change in making heatwaves hotter and more frequent has come into focus. At a broader level, greenhouse gas emissions from human activities have heated the planet by about 1.2 degrees Celsius since pre-industrial times. These grim predictions have brought attention to a range of mitigation measures. One such initiative to bring greenery back to urban spaces in Spain involves installing vegetated awnings or canopies.
What are vegetated canopies?
Introduced in Santa Maria Street in Valladolid, Spain, the awnings are tensioned sail-like structures that have been anchored to the facades of surrounding buildings. They mimic natural canopies found in forests and various plant species.
The lightness and ease of installation of the ‘Greenshades’ allow for shade and the presence of greenery in commercial streets and public spaces, where trees or other vegetation are often absent.
Here is how they work:
The sails with anchors and supports are prepared by laying down the specific geotextile substrate or material. An irrigation system is installed at the highest side, from where the water falls by gravity, soaking the entire substrate.
In addition to water, fertilizer keeps the vegetation in perfect condition. The excess water is collected at the lowest point and into a connected drainage system.
The seed mixture is then projected onto the geotextile. After four months, the shade is expected to be completely covered with vegetation.
The awnings can be placed in streets, where planting trees may not be feasible owing to the lack of space. The plants grow hydroponically, with a water supply point and water outlet for draining purposes.
What are their advantages?
The plants chosen for these awnings belong to species that are optimised for the absorption of gases such as carbon monoxide and nitrogen oxide.
The substrate also absorbs sound waves, reducing noise pollution. A square metre of a vegetated canopy generates the oxygen required by a person for the whole year, apart from filtering harmful gases, according to the company.
The hanging planter also allows for the centralisation of water and light installations.
This is meant to induce savings as the lights are equipped with movement sensors that illuminate the street according to its need.
The adoption of such canopies could eventually contribute to urban biodiversity, creating a healthier ecosystem that supports a variety of wildlife.

IPBES report on Biodiversity loss
GS Paper - 3 (Environment)
In the most extensive study on invasive species carried out till date, the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) in its new publication – the “Assessment Report on Invasive Alien Species and their Control’’ – has found that there are 37,000 alien species, including plants and animals, that have been introduced by many human activities to regions and biomes around the world, including more than 3,500 invasive alien species and that invasive alien species have played a key role in 60% of global plant and animal extinctions recorded.
Highlight of the report
The report, which was released on 4 September 2023, said that invasive alien species are one of the five major direct drivers of biodiversity loss globally, alongside land and sea use change, direct exploitation of organisms, climate change, and pollution.
The report has noted that the number of alien species (species introduced to new regions through human activities) has been rising continuously for centuries in all regions, but are now increasing at unprecedented rates, with increased human travel, trade and the expansion of the global economy.
Not all alien species establish and spread with negative impacts on biodiversity, local ecosystems and species, but a significant proportion do – then becoming known as invasive alien species.
About 6% of alien plants; 22% of alien invertebrates; 14% of alien vertebrates; and 11% of alien microbes are known to be invasive, posing major risks to nature and to people, the IPBES has said.
The report further noted that many invasive alien species have been intentionally introduced for their perceived benefits, “without consideration or knowledge of their negative impacts’’ – in forestry, agriculture, horticulture, aquaculture, or as pets.
Nearly 80% of the documented impacts of invasive species on nature’s contribution to people are negative.
The water hyacinth is the world’s most widespread invasive alien species on land. Lantana, a flowering shrub, and the black rat are the second and third most widespread globally. The brown rat and the house mouse are also widespread invasive alien species.
The report said that the annual costs of invasive alien species have at least quadrupled every decade since 1970, as global trade and human travel increased. In 2019, the global economic cost of invasive alien species exceeded $423 billion annually.
These trends are projected to accelerate as the global economy expands, land and seas are used more intensively, and demographic change takes place, the report said.
Invasive alien specieslike Aedes albopictus and Aedes aegyptii spread diseases such as malaria, Zika and West Nile Fever, while others also have an impact on livelihood such as the water hyacinth in Lake Victoria in East Africa led to the depletion of tilapia, impacting local fisheries.
The IPBES report has further warned thatwarming temperatures and climate change could favour the “expansion of invasive species’’.
Flashback
The IPBES released its report following a week- long plenary from 28th August, with representatives of the 143 member States which have approved the report.
IPBES is an independent intergovernmental body established to strengthen the science-policy interface for biodiversity and ecosystem services, working in a similar way to the IPCC, which is the UN’s climate science body.
The study, which has taken place over a period of four years, has been by 86 leading experts from 49 countries, drawing on more than 13,000 references.

Genome secrets of Indian oil sardine
GS Paper - 3 (Biotechnology)
In a major breakthrough in marine fisheries research, a team of scientists at the ICAR-Central Marine Fisheries Research Institute (CMFRI) has decoded the whole genome of the Indian oil sardine, a popular food fish. This is the first time that the genome of a marine fish species from the Indian subcontinent has been decoded, a CMFRI statement said.
More about the News
This development is a 'milestone' in Indian marine fisheries, the decoded genome will be a valuable resource for understanding the biology, ecology and evolution of the oil sardine (Sardinella longiceps).
This critical genome data could be used to improve the management strategies for the conservation and sustainable utilisation of this fish.
The decoded genome is 1.077 Gb in size and contains a total of 46316 protein coding genes.
This landmark research accomplishment was achieved through the cutting-edge Next Generation Sequencing technology by a group of researchers led by Dr Sandhya Sukumaran, Principal Scientist at Marine Biotechnology division of the CMFRI. This research has been published in the high-impact journal Scientific Data of the Nature Group.
Indian oil sardine is a vital fisheries resource in the Indian subcontinent, contributing substantially, approximately 10 per cent, to the total marine fisheries industry in India.
This fish is a trans-boundary resource and the whole genome information can also be utilised for certification of the fishery and identification of the origin of catch for monitoring clandestine trade and tracking the movement of this enigmatic fish.
Small pelagic fishes like the Indian oil sardines can be considered as model organisms to study the climatic as well as fishing impacts on the Indian Ocean resources, as they respond to variations in environmental and oceanographic parameters.
About Sardines
Sardines are an ecologically important part of the marine ecosystem, as they form an intermediate link in the food web and serve as prey for larger predators.
The genome assembly of the sardines is a valuable tool for studying how fish adapt to climate change.
Genetic and genomic investigations found that Indian oil sardines exist in two highly distinct stocks, one in Indian waters and another in the Gulf of Oman.
Understanding these genetic differences could help researchers comprehend how environmental and oceanographic conditions impact this species in different regions of the Northern Indian Ocean.
The CMFRI statement said the researchers have also identified the genes involved in the biosynthesis of polyunsaturated fatty acids (PUFA) of the oil sardine, offering insights into the genomic mechanisms behind the high nutritional quality of these sardines.
Oil sardines are a good source of these fatty acids, which play a crucial role in maintaining human health.
