Development:
Collaborative Effort: Created through a joint initiative by the Ministry of Agriculture and the Department of Space.
Prerana Programme
Why in News: Recently, the Union Minister of Education met with students, teachers, parents of PM SHRI Schools, and alumni of the Prerana Programmes.
About Prerana Programme
- Launch: Initiated in January 2024 by the Union Education Ministry.
- Objective: Aims to integrate principles of the Indian education system with the value-based education philosophy outlined in the National Education Policy (NEP) 2020.
Program Details:
- Duration and Format: A week-long residential program designed for selected students from classes IX to XII.
- Learning Approach: Combines experiential and inspirational learning with advanced technology, blending heritage and innovation.
- Participant Details: Each week, a batch of 20 students (10 boys and 10 girls) from various regions of the country participates.
Location:
Conducted at a Vernacular School in Vadnagar, Mehsana District, Gujarat, which was established in 1888.
Curriculum:
Developed by: IIT Gandhinagar.
Value-Based Themes: The curriculum is centered around nine key themes:
- Swabhiman and Vinay (Self-Respect and Humility)
- Shaurya and Sahas (Courage and Bravery)
- Parishram and Samarpan (Hard Work and Dedication)
- Karuna and Sewa (Compassion and Service)
- Vividhta and Ekta (Diversity and Unity)
- Satyanishtha and Shuchita (Truthfulness and Purity)
- Navachar and Jigyasa (Innovation and Curiosity)
- Shraddha aur Vishwas (Faith and Trust)
- Swatantrata and Kartavya (Freedom and Responsibility)
Significance:
The program is designed to inspire youth and promote respect for India’s unity in diversity, reflecting the spirit of “Vasudhaiva Kutumbakam” (The world is one family).
Gastrodia indica
Why in News: A distinctive orchid species, Gastrodia indica, was recently found in the Fambonglho Wildlife Sanctuary in Sikkim.
About Gastrodia indica
Unique Characteristics:
- Flowering: It is the first orchid species from India that never opens its flower.
- Elevation: Found at elevations of 1,950–2,100 metres above sea level.
- Species Type: First cleistogamous species of the genus Gastrodia discovered in India.
Botanical Traits:
- Genus: Gastrodia, known for terrestrial, herbaceous, and holomycotrophic orchids.
- Cleistogamous Nature: Does not rely on external pollinators (insects or wind) for reproduction, as it self-pollinates internally.
- Holomycotrophic: Lacks chlorophyll and depends entirely on a fungal host for nutrients, drawing carbon from underground fungi.
- Allied Species: Morphologically related to G. exilis and G. dyeriana, but exhibits significant differences in floral morphology upon closer examination.
Habitat:
- Environment: Thrives in dense, rotten leaf litter.
- Associated Trees: Found in association with trees such as Magnolia doltsopa, Acer campbelli, and Quercus lamellose.
Significance:
The discovery adds to India’s botanical diversity, increasing the total number of Gastrodia species in the country to 10.
Threats:
Faces potential threats due to its limited population and specific habitat requirements.
Zoopharmacognosy — How Animals Self-Medicate
Why in News: A recent article published in the May 2, 2024, issue of the journal Nature highlights a Sumatran orangutan’s use of the plant Fibraurea tinctoria to treat a facial wound, bringing attention to the phenomenon of zoopharmacognosy, where animals self-medicate using natural substances.
About Zoopharmacognosy
Zoopharmacognosy refers to the behavior of animals self-medicating by using natural substances like plants, soil, or insects to treat illnesses, infections, or to enhance their overall health.
Origin of the Term: The term was coined by ecologist D.H. Janzen from the University of Pennsylvania. It combines “zoo” (referring to animals) and “pharmacognosy” (the study of medicinal drugs derived from natural sources).
Examples of Self-Medication:
- Primates: Sumatran orangutans have been observed using the plant Fibraurea tinctoria to treat wounds.
- Herbivores: Elephants in Kenya eat certain plants to induce labor.
- Domestic Animals: Dogs often eat grass to induce vomiting and rid themselves of stomach infections.
Historical Perspective:
- The practice of self-medication in animals has been noted for centuries, with ancient naturalists like Pliny the Elder observing animals using medicinal plants.
Relevance to Human Medicine:
- Many plants used by animals have also been integral to traditional human medicine systems such as Ayurveda and Traditional Chinese Medicine (TCM). For example, Aloe vera, used by animals for its healing properties, is a common remedy in these traditions.
Scientific Studies:
- Recent studies, such as the one published in Nature in May 2024, continue to explore and document these behaviors, offering insights into potential new medicinal compounds that could be developed for human use.
Potential for Drug Discovery:
- The study of zoopharmacognosy offers valuable leads for biochemists and pharmaceutical companies to identify new natural product molecules for drug development. The observed behaviors of animals in the wild can guide researchers to promising compounds that may otherwise go unnoticed.
