Climate change aiding spread of CCHF virus
GS Paper - 3 (Health and Diseases)

As Europe reels under a heatwave and wildfires, the rising temperatures have also raised fears of spread of viruses generally not found in colder climates. Alert has been sounded about the Crimean-Congo haemorrhagic fever (CCHF), an infection spread by ticks that has a high fatality rate, according to the World Health Organization (WHO). The CCHF is endemic to Africa, the Balkan countries, Middle East, and parts of Asia.

What is CCHF?

According to the WHO, Crimean-Congo haemorrhagic fever (CCHF) is a viral haemorrhagic fever usually transmitted by ticks. It can also be contracted through contact with viraemic animal tissues (animal tissue where the virus has entered the bloodstream) during and immediately post-slaughter of animals.
CCHF outbreaks constitute a threat to public health services as the virus can lead to epidemics, has a high case fatality ratio (10–40%), potentially results in hospital and health facility outbreaks, and is difficult to prevent and treat.”
The virus is present in the tick family of insects. According to the US Centers for Disease Control and Prevention (CDC), animals such as cattle, goats, sheep and hares serve as amplifying hosts for the virus. Transmission to humans occurs through contact with infected ticks or animal blood.
CCHF can be transmitted from one infected human to another by contact with infectious blood or body fluids”, such as sweat and saliva. The ticks can also be hosted by migratory birds, thus carrying the virus over long distances.
While the disease was first detected among soldiers in the Crimean Peninsula (near the Black Sea) in 1944, in 1969, it was found that an ailment identified in the Congo Basin was caused by the same pathogen. Thus, the disease was named the Crimean-Congo haemorrhagic fever.
What are the symptoms, cure of CCHF?

CCHF symptoms include fever, muscle ache, dizziness, neck pain, backache, headache, sore eyes and sensitivity to light, according to the WHO.
There may be nausea, vomiting, diarrhoea, abdominal pain and sore throat early on, followed by sharp mood swings and confusion. After 2–4 days the agitation may be replaced by sleepiness, depression and lassitude.
There is no vaccine for the virus in either humans or animals, and treatment generally consists of managing symptoms.
According to the WHO, the antiviral drug ribavirin has been used to treat CCHF infection with apparent benefit.

‘Sponge cities’ not stopped the floods
GS Paper - 1 (Geography)

China has been hit by devastating floods, inundating cities and causing deaths and infrastructural damage, as well as raising questions about the effectiveness of its 2015 “sponge city” initiative aimed at reducing urban flood risks. The initiative was launched to boost flood resilience in major cities and make better use of rainwater through architectural, engineering and infrastructural tweaks.

Why was the initiative launched?

China has long sought to improve the way it handles extreme weather, and make highly populated cities less vulnerable to flooding and drought.
The “sponge city” initiative was designed to make greater use of lower-impact “nature-based solutions” to better distribute water and improve drainage and storage.
Those solutions included the use of permeable asphalt, the construction of new canals and ponds and also the restoration of wetlands, which would not only ease waterlogging, but also improve the urban environment.
Breakneck urbanisation has encased vast stretches of land in impermeable concrete, often along banks of major rivers that traditionally served as flood plains. With wetlands paved over and nowhere for surplus water to settle, waterlogging and flooding was commonplace.

What has been done so far?

Studies show that many of the local pilot initiatives launched so far have had a positive effect, with low-impact projects like green roofs and rain gardens reducing run-offs.
But implementation has so far been patchy. A total of 30 pilot sponge cities were selected in 2015 and 2016.
By last year, only 64 of China’s 654 cities had produced legislation to implement sponge city guidelines, researchers said in January.
The researchers said the government had so far paid “minimum attention” to sponge city construction, and called for national legislation to be drawn up as soon as possible.

What are the limitations of sponge cities?

Even if sponge city measures had been implemented in full, they would have been unable to prevent this year’s disasters.
Zhengzhou in Henan province was one of the most enthusiastic pioneers of sponge city construction, allocating nearly 60 billion yuan to the programme from 2016 to 2021. But it was unable to deal with its heaviest rainfall in history in 2021.
Experts believe sponge city infrastructure can only handle no more than 200 millimetres (7.9 inches) of rain per day.
At the height of the rainstorms that lashed Beijing at the end of July, rainfall at one station reached 745 millimetres over three and a half days. In July 2021, Zhengzhou saw rainfall in excess of 200 mm in just one hour.
Authorities are also playing catch-up to climate change. This year’s heavy rain hit cities in the normally arid north, where sponge city development is less advanced.

Net zero carbon emission country
GS Paper - 3 (Environment)

Bhutan has emerged as a country with net zero emissions and not only curbed its carbon footprints, but has also transformed into a carbon sink, absorbing more carbon dioxide (CO2) than releasing, It reported that the recent report from the World Economic Forum revealed that the eight countries including Bhutan have attained an impressive feat of net zero emissions.

More about the News

Bhutan is one among the 196 nations that committed to the Paris Agreement during the UN Climate Change Conference focused on restricting global temperature increases to 1.5 degree Celsius above pre-industrial levels.
Apart from Bhutan, Comoros, nestled in the Indian Ocean and Gabon in Central Africa have managed to control the carbon emissions and set an example for other countries.
Comoros, by conscientiously managing its agricultural, fishing, and livestock sectors, complemented by rigorous environmental safeguards has maintained low emissions.
Bhutan's unique success as the first nation to achieve net zero emissions is rooted in its population of 8,00,000 and its remarkable forest coverage of 70%.
Why this achievement

The nation prioritizes sustainable organic farming and forestry practices, accentuated by the reliance on hydropower and the prudent management of its main economic driver, tourism.
Notably, Bhutan charges a $200 sustainable development fee per day from tourists, underscoring the value placed on eco-tourism and environmental protection.
It has been reported that another reason behind this control of emissions is the forests being an intrinsic part of its spiritual heritage.
Guided by a climate-conscious forest economy, Bhutan mitigates greenhouse gas emissions, preserves wildlife habitats, mitigates forest fires, and practices sustainable forest management for timber, fruit, and rubber - fostering a circular economy.
The nation has embarked on pilot projects that explore sustainable timber construction, showcasing innovative solutions.
Bhutan's journey to net zero emissions, fueled by an unyielding commitment to its environment and cultural heritage, is a source of inspiration for the world.
As nations navigate the complexities of climate change, Bhutan's story beckons us to embrace sustainable practices and safeguard our precious planet.

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.

G20 agrees to give African Union membership
GS Paper - 2 (International Relations)

Group of 20 nations agreed to grant the African Union permanent membership status, and leaders are expected to announce the decision during a summit in India. The move would give the 55-member African Union, which is currently classified as an “invited international organization,” the same status as the EU. It’s part of a drive to provide African countries with a stronger voice on global issues such as climate change and emerging-market debt, particularly as emerging markets in the so-called Global South take on a more prominent role in world affairs.

More about the News

Prime Minister Narendra Modi, who is hosting the G20 summit, has made it a priority to grant the African Union full membership.
Countries like Germany, Brazil, and Canada have also expressed their support for African Union membership to the G20.
The G20 or Group of 20 is an intergovernmental forum of the world's major developed and developing economies.
The members represent around 85% of global GDP, over 75% of global trade, and about two-thirds of the world population.
The European Union is keen to take some credit for the G20 step. Leaders from the bloc plan to hold a high-level meeting with African leaders on the sidelines of the summit, which is being skipped by Chinese President Xi Jinping and Russian leader Vladimir Putin.
Dubbed a “mini-summit,” the Europe-Africa meeting will include a discussion of the consequences of Russia’s war against Ukraine on global food security — a situation that threatens to escalate after Putin refused to revive a UN-backed deal to allow grain shipments after talks with Turkish President Recep Tayyip Erdogan.
Other topics include efforts to reform the global financial architecture, improving conditions for private investments and infrastructure projects in Africa, as well as the situation in the Sahel region.
Flashback
The African Union (AU) is a continental body consisting of the 55 member states that make up the countries of the African Continent.
It was officially launched in 2002 as a successor to the Organisation of African Unity (OAU, 1963-1999).
