The lockdowns introduced in 2020 to curb the spread of COVID-19 saw the narrative “nature is healing” gain prominence. However, the notion that nature, in the absence of people, was healing fizzled out fairly quickly with the emergence of fresh environmental challenges, most notably, the resurgence of single-use plastics. This blog examines the ecological fallout of the pandemic and suggests policy options for Sri Lanka to avert the looming environmental disaster.

The UNESCO-listed Wolong National Nature Reserve, a prime habitat for the endangered panda, was badly damaged by the 2008 Sichuan earthquake. To rebuild the reserve into an ecologically sustainable area, Dr Lewis Cheung Ting-on, Associate Professor at the Department of Social Sciences, The Education University of Hong Kong (EdUHK), and his research team devised two unique accreditation systems for the ecotourism industry, one for tourism businesses and one for ecotour guides, as part of the regulations for the tourism development in the ecologically sensitive reserve. The guidelines included holistic recommendations for ecotourism planning, activities, infrastructure and marketing. In 2016, the local administration in Wolong implemented the recommendations in full. This was the first regional ecotourism certification programme in a protected area in China and it has had a positive influence on the ecotourism development in other protected areas in the mainland and in Taiwan.

Collecting coral probiotics from seawater instead of coral
13 Oct 2021
Coral reefs, comprising some of the most diverse and delicate ecosystems under water, are under immense stress. From global warming to pollution to pathogens, many of the reef-building coral species are listed as threatened or endangered. But, according to researchers in Japan, the corals may have an unlikely ally: bacteria.

Researchers in Japan have found an energy-efficient way to convert the chief greenhouse gas carbon dioxide (CO2) into useful chemicals. Using the method, CO2 is transformed into structures called metal-organic frameworks (MOFs), suggesting a new and simpler route to dispose of the greenhouse gas to help tackle global warming.

Accommodation for young people in Hong Kong has long been at the top of the policy agenda. Recent research conducted by Lingnan University in Hong Kong (LU) and the City University of Hong Kong on the younger generation’s housing opportunities finds that 26 per cent of parents who responded expect to subsidise their adult children when they buy a property. Findings also suggest reliance on the family is now increasingly frequent, and important to young adults who wish to live independently and have a choice.

A recent study conducted by the Science Unit of Lingnan University in Hong Kong (LU) shows that concentrations of fine particulate matter (PM2.5) from incense burning both inside and outside temples could be 6 times and 4 times of the recommended levels respectively. In addition, the more temples there are in the same district, the higher the respiratory mortality rate. The research team suggests that alternative measures, such as installation of automatic mist sprayers to reduce smoke dispersion, as well as using incense made with non-toxic substances to minimise health risks to worshippers and neighbours, should be considered.
Accumulation of POPs-like contaminants in raptors
03 Sep 2021
Knowledge of the detailed accumulation profiles of persistent organic pollutants (POPs) and POPs-like contaminants in wild animals is critical for ecological risk assessment. Comprehensive screening of organohalogen compounds in the livers of wild birds from Osaka, Japan using two-dimensional gas chromatography in combination with high resolution time-of-flight mass spectrometry (GC×GC–HRToFMS) revealed specific accumulation of typically unmonitored POPs-like compounds in raptors.

A collaboration between Osaka City University and Setsunan University sheds light on the effect urbanization has on the flesh fly species Sarcophaga similis. Through a series of laboratory and in-field experiments, scientists show that an increase in nighttime illumination and temperature, two of the major characteristics of urbanization, can postpone S. similis hibernation anywhere from 3 weeks to a month.

Exposure of a PCB metabolite to whale-derived induced neurons caused apoptosis and neurodegeneration
26 Jul 2021
Using neurons directly reprogrammed from tissues of stranded whales to assess brain health A research team of the Center for Marine Environmental Studies (CMES) of Ehime University, Japan succeeded for the first time in direct reprogramming of whale somatic cells to neuronal cells, and conducted a neurotoxicity test using these cells. Exposure to a metabolite (4′OH-CB72) of polychlorinated biphenyls, ubiquitous environmental pollutants, caused apoptosis in the reprogrammed neurons. Transcriptome analysis of 4′OH-CB72-treated whale neurons showed altered expressions of genes associated with oxidative phosphorylation, chromatin degradation, axonal transport, and neurodegenerative diseases.

Using a CeO2 catalyst, researchers develop an effective catalytic process for the direct synthesis of polycarbonate diols without the need for dehydrating agents. The high yield, high selective process has CO2 blown at atmospheric pressure to evaporate excess water by-product allowing for a catalytic process that can be used with any substrate with a boiling point higher than water.

Giants in history

Tetsuya Theodore Fujita (23 October 1920 – 19 November 1998) was a Japanese-American meteorologist who created the Fujita scale that classifies the strength of tornadoes based on damage to structures and vegetation.
Archana Sharma (16 February 1932 - 14 January 2008) conducted research into plant and human genetics that expanded the understanding of both botany and human health. In relation to botany, she uncovered the means by which asexually-reproducing plants evolve into new species.
Roseli Ocampo-Friedmann (23 November 1937 – 4 September 2005) was a Filipino-American scientist whose research focused on cyanobacteria and microorganisms that inhabit extreme environments.
Edgardo Dizon Gomez (7 November 1938 – 1 December 2019) was a Filipino marine biologist who recognized the need to protect marine resources, especially coral reefs, in the Philippines.
Anna Mani (23 August 1918 – 16 August 2001) was an Indian meteorologist who contributed significantly to the understanding of solar radiation, ozone and wind energy by developing a wide range of measurement tools. One of India’s pioneering female scientists, Mani excelled in the male-dominated area of meteorology and became the Deputy Director-General of the India Meteorological Department.
Võ Quý (1929 – 2017) was a Vietnamese ornithologist who studied the destruction of tropical forests and agricultural lands in Vietnam by Agent Orange, a herbicide used by the U.S. military during the Vietnam War. In addition to planning forest restoration projects, Quý rediscovered the rare eastern sarus crane, an endangered species that had vanished during the war.
