  • The serial nomination was forwarded by the Archaeological Survey of India to UNESCO through the Ministry of Culture. UNESCO has accepted the nomination in Tentative Lists of its World Heritage Site.
  • According to the World Heritage Convention’s operational guidelines, a tentative list is an “inventory” of properties a country believes deserves to be a World Heritage Site. After UNESCO includes a property in the Tentative List, that country has to be prepare a nomination document that will be considered by the UNESCO World Heritage Committee.

Invasive white flies

  • The first invasive whitefly reported was from Kerala in 1995. It has now spread across the country.
  • A study has now detailed the damage caused by the pest. It extracted genomic DNA from individual adult white flies and explained in detail about eight invasive species found in India.

Distribution

  • Most of these whitefly species are native to the Caribbean is lands or Central America [or both]. It is difficult to pin point how they entered our country. Most probably a nymph or baby insect may have come along with imported plants. Nowadays with globalisation, it is also possible that tourists may have brought the insect along with plants.

·   The first reported invasive spiralling whitefly Aleurodicusdispersus is now distributed throughout India except Jammu & Kashmir.

  • The rugose spiralling whitefly which was reported in Pollachi, Tamil Nadu in 2016 has now spread throughout the country including the islands of Andaman Nicobar and Lakshadweep. Approximately 1.35 lakh hectares of coconut and oil palm in India are affected by the rugose spiralling whitefly.

Reason behind spread

  • The host range of all of the invasive whiteflies was increasing due to their polyphagous nature (ability to feed on va- rious kinds of food) and prolific breeding.
  • Aleurodicus dispersus and Aleurodicus rugioperculatus have been reported on over 320 and 40 plant species, respectively.

Other invasive white flies were also found to expand their host range on valuable plants species, especially coconut, banana, mango, sapota, guava, cashew, oil palm, and ornamental plants such as bottle palm, false bird of paradise, butterfly palm and important medicinal plants.

Control

  • White flies are difficult to control by using synthetic insecticides, and hence currently naturally occurring insect predators, parasitoids and entomopathogenic fungi (fungi that can kill insets) are being used. They are not just environmentally friendly but also economically feasible.
  • Entomopathogenic fungi specific to white flies are isolated, purified, grown in the lab or mass-produced and applied into the white fly infested field in combination with the release of lab reared potential predators and parasitoids,
  • Continuous monitoring of the occurrence of invasive species, their host plants and geo graphical expansion is needed, and if required, import of potential natural enemies for bio control programmes can also be carried out.

Naming of cyclones

  • Whenever a cyclone hits a country, the first thing that strikes the minds of most are what these names mean.
  • Tauktae cyclone was named by Myanmar, means “gecko” — a highly vocal lizard — in Burmese dialect.
  • Yaas has been named by Oman. Yaas refers to a tree that has a good fragrance and in English; the word is similar to Jasmine.

How are the cyclones named?

  • In 2000, a group of nations called WMO/ESCAP (World Meteorological Organisation/United Nations Economic and Social Commission for Asia and the Pacific), which comprised Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, decided to start naming cyclones in the region. After each country sent in suggestions, the WMO/ESCAP Panel on Tropical Cyclones (PTC) finalised the list.
  • The WMO/ESCAP expanded to include five more countries in 2018 — Iran, Qatar, Saudi Arabia, United Arab Emirates and Yemen.

The list of 169 cyclone names released by IMD in April 2020 were provided by these countries — 13 suggestions from each of the 13 countries.

Why is it important to name cyclones?

  • Adopting names for cyclones makes it easier for people to remember, as opposed to numbers and technical terms.
  • It also helps the scientific community, the media, disaster managers etc.
  • With a name, it is easy to identify individual cyclones, create awareness of its development, rapidly disseminate warnings to increased community preparedness and remove confusion where there are multiple cyclonic systems over a region.

What are the guidelines to adopt names of cyclones?

While picking names for cyclones, here are some of the rules that countries need to follow. If these guidelines are following, the name is accepted by the panel on tropical cyclones (PTC) that finalises the selection:

  • The proposed name should be neutral to (a) politics and political figures (b) religious believes, (c) cultures and (d) gender
    • Name should be chosen in such a way that it does not hurt the sentiments of any group of population over the globe
    • It should not be very rude and cruel in nature
    • It should be short, easy to pronounce and should not be offensive to any member

o    The maximum length of the name will be eight letters

  • The proposed name should be provided with its pronunciation and voice over

o    The names of tropical cyclones over the north Indian Ocean will not be repeated. Once used, it will cease to be used again. Thus, the name should be new.

What cyclone names has India suggested?

  • The 13 names in the recent list that have been suggested by India include: Gati, Tej, Murasu, Aag, Vyom, Jhar (pronounced Jhor), Probaho, Neer, Prabhanjan, Ghurni, Ambud, Jaladhi and Vega.
  • Some of the names picked by India were suggested by the general public. An IMD committee is formed to finalise the names before sending it to the PTC.

Here is the complete list of 169 names. The first cyclone name which will be chosen will be the one in the first row of the first column — Nisarga by Bangladesh. Next, India’s choice, Gati, will be chosen, and so on.

Processing unit of PARF has been certified by APEDA under its accredited Organic Certification.

National Programme for Organic Production (NPOP)

. Under the NPOP, organic products are grown under a system of agriculture without the use of chemical fertilizers and pesticides with an environmentally and socially responsible approach.
