Geographical Indication (GI) Tag Blog Image

Overview:

Seven products from Odisha, ranging from the Similipal Kai chutney made with red weaver ants to the embroidered Kapdaganda shawl, have bagged the coveted Geographical Indication (GI) tag.

About Geographical Indication (GI) Tag

  • It is a sign used on products that have a specific geographical origin and possess qualities or a reputation that are due to that origin.
  • This is typically used for agricultural products, foodstuffs, wine and spirit drinks, handicrafts and industrial products.
  • The Geographical Indications of Goods (Registration and Protection) Act, 1999 seeks to provide for the registration and better protection of geographical indications relating to goods in India.
  • This GI tag is valid for 10 years following which it can be renewed.

Key facts about new GI Tagged products

  • Kapdaganda Shawl
    • It is woven and embroidered by the women of the Dongria Kondh tribe, a particularly vulnerable tribal group (PVTG) in the Niyamgiri hills in Odisha’s Rayagada and Kalahandi districts.

  • Nayagarh Kanteimundi Brinjal
    • It is known for its prickly thorns on the stems and the whole plant.
    • The green and round fruits contain more seeds as compared to other genotypes.
    • It is famous for its unique taste and relatively short quick cooking time.
    • The plants are resistant to major insects and can be grown with minimal pesticide.
  • Odisha Khajuri Guda (Jaggery)
    • It is a natural sweetener extracted from date palm trees and has its origin in the Gajapati district.
    • Traditionally, the jaggery is prepared in a trapezoidal form called ‘Patali Gur’ and is organic by nature. It is dark brown and has a unique taste.
  • Dhenkanal Magji
    • It is a type of sweet made from cheese from buffalo milk, with distinct characteristics in terms of appearance, taste, flavour, shape, and size.

Q1) Who is Dongria kondh?

The Dongria kondh is a primitive subgroup of kondhs. They are a particularly vulnerable tribal group residing mostly in Trilochanpur gram panchayat under Lanjigarh Block of Kalahandi.

Overview:

The Indian Institute of Spices Research (IISR) Kozhikode has successfully developed a new granular lime-based Trichoderma formulation.

About Trichoderma

  • The formulation named ‘Tricholime’, integrates Trichoderma and lime into a single product, making the application easier for farmers. 
  • Trichoderma is a fungal biocontrol agent, has proven effective in suppressing several soil-borne plant pathogens and serves as a successful bio-pesticide and bio-fertilizer in crop production.
  • Recognizing the importance of Trichoderma and the challenges posed by traditional lime applications, the scientists at IISR developed ‘Tricholime’ to integrate lime and Trichoderma.

Significance of Tricholime

  • It can successfully eliminate the need for a time-consuming two-step process.
  • This lime-based formulation neutralizes the soil acidity while promoting plant growth and shields crops from soil-borne pathogens, all in a single application.
  • This formulation also benefits the crop by improving the physical condition of the soil, enhancing secondary nutrient availability and by boosting soil microbial activity, he added.
  • IISR hopes that the technology behind this product can also be extended to include other beneficial bio-agents, opening new possibilities in product development to support sustainable organic farming.

Q1) What are Biopesticides?

Biopesticides are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. For example, canola oil and baking soda have pesticidal applications and are considered biopesticides.

Sponge farming Blog Image

Overview:

Warming oceans forced women in Zanzibar to switch from seaweed to climate-resilient sponge farming to stay afloat.

About Sponge farming

  • Sponge farming is a relatively new business opportunity that does not harm the marine environment.
  • A sponge is a living animal which is made of loosely arranged cells that surround a skeleton of fibres.
  • The specialised cells nestled within thousands of tiny chambers act as microscopic pumps, and tirelessly drawing water into the sponge’s body with their whip-like tails.
  • Sponges provide homes for many other animals, plants, and microorganisms. In many cases, they all work together in a mutual symbiotic relationship.
  • Sea sponges exist in all oceans around the world and make up 20% of the global silicon biological sink.
  • This unique pumping mechanism, which helps sponges extract nutrition and oxygen, also purifies the ocean water by removing impurities, including sewage.
  • Uniqueness: Sponges, unlike seaweed, possess remarkable resilience to climate change, require minimal maintenance, and command premium market prices,
  • Reproduction: Most sponges are hermaphrodites, harbouring both male and female reproductive organs, enabling them to self-propagate effortlessly.
  • New sponges emerge from small buds that detach from the parent sponge and begin independent growth.
  • Even damaged or fragmented sponges can regenerate into new individuals.
  • This remarkable regenerative ability underpins the ease and feasibility of commercial sponge farming.
  • Uses:
    • These sponges are used for bathing and general hygiene because they are naturally antibacterial and antifungal and can resist odours.
    • Research has also shown that the spongy creatures play an important role themselves in combating climate change.
    • Their skeletons break down into microscopic pieces of silicon, which helps control the carbon cycle in the ocean and reduces the greenhouse effect.
    • Dissolved silicon is critical for the growth of diatoms, tiny organisms which absorb large amounts of CO2 in the ocean using photosynthesis.

Q1) What is a Symbiotic relationship?

It is the close associations formed between pairs of species. They come in a variety of forms, such as parasitism (where one species benefits and the other is harmed) and commensalism (where one species benefits and the other is neither harmed nor helped).

  • For the most part it is sedentary and does not migrate.
  • Males tend to be territorial and mark their territory with glandular secretions.
  • This species exhibits sexual dimorphism. The females are slightly smaller than males and lack antlers.
  • Distribution
    • It has a native geographic range throughout India, including the Himalayan foothill zone and Southeast Asia, including Burma and Thailand.
    • Humans have introduced free-ranging populations of this deer in Sri Lanka, Australia and the United States, including Texas, Florida, and Hawaii.
  • Habitat:
    • It appears to prefer dense forests; however, they are often observed in clearings, grasslands and occasionally wet grasslands.
    • This variation is usually associated with time of year and food distribution.
  • Conservation status
    • IUCN: Endangered
    • Wildlife Protection Act 1972: Scheduled I 

Key facts about the Rajaji Tiger Reserve

  • It is spread over three districts of Uttarakhand: Haridwar, Dehradun and Pauri Garhwal.

Q1) What are Shivalik Hills?

These are a sub-Himalayan Mountain Range running 1,600 km long from the Teesta River, Sikkim, through Nepal and India, into northern Pakistan. The range runs parallel with the Himalayan system from Haridwar on the Ganges to the banks of the Beas River. The hills have an average height of 900 to 1,200 m. They are chiefly composed of low sandstone and conglomerate hills, the solidified and up-heaved detritus of the great range in their rear, the intermediate valley lying between the outer hills and the Mussoorie.
