Agro Biodiversity Hotspots in India – UPSC

In this article, You will read Agro Biodiversity and Agro Biodiversity Hotspots in India – for UPSC IAS.

Agro Biodiversity

Agrobiodiversity is the result of the interaction between the environment, genetic resources, and management systems and practices used by culturally diverse people. This is the result of both natural selection and human invention developed over millennia.

  • It comprises the diversity of genetic resources (varieties, breeds) and species used for food, fodder, fibre, fuel, and pharmaceuticals.
  • It also includes the diversity of non-harvested species that support production (soil microorganisms, predators, pollinators), and those in the wider environment that support agro-ecosystems (agricultural, pastoral, forest, and aquatic) as well as the diversity of the agro-ecosystems.

Benefits of Agrobiodiversity

  • Increases productivity, food security, and economic returns.
  • Reduces the pressure of agriculture on fragile areas, forests, and endangered species.
  • Makes farming systems more stable, robust, and sustainable.
  • Contributes to sound pest and disease management
  • Conserves soil and increases natural soil fertility and health.
  • Reduces dependency on external inputs.
  • Improves human nutrition and provides sources of medicines and vitamins.
  • Conserve ecosystem structure and stability of species diversity.

Significance of Agrobiodiversity for India

India’s promising genetic resources include rice from Tamil Nadu (Konamani), Assam (Agni bora) and Kerala (Pokkali), Bhalia Wheat and mushroom (Guchhi) from Himachal Pradesh, and rich farm animal native breeds — cattle (42), buffaloes (15), goat (34), sheep (43) and chicken (19). Since, genetic diversity of crops, livestock, and their wild relatives, are fundamental to improve crop varieties and livestock breeds, this can help in the following ways:

  • In combating hunger: India is ranked 102 in the Global Hunger Index (GHI) out of 117 qualified countries.
    • Hunger is defined by caloric deprivation; protein hunger; hidden hunger by the deficiency of micronutrients.
  • Malnutrition: Nearly 47 million or four out of 10 children in India do not meet their potential because of chronic undernutrition or stunting.
    • This leads to diminished learning capacity, increased chronic diseases, low birth-weight infants from malnourished parents.
    • The global nutrition report pegs 614 million women and more than half the women in India aged 15-49 as being anaemic.
  • Agrobiodiversity can help in nutrition-sensitive farming and bio-fortified foods.
    • For instance, moringa (drumstick) has micronutrients and sweet potato is rich in Vitamin A. There are varieties of pearl millet and sorghum rich in iron and zinc.
  • This will help India achieve UN Sustainable Development Goal 2 (Zero Hunger) and the Aichi Biodiversity Target (focuses on countries conserving the genetic diversity of plants, farm livestock and wild relatives).

Agrobiodiversity In India

  • Across the world, 37 sites are designated as Globally Important Agricultural Heritage Systems (GIAHS), of which three are Indian — Kashmir (saffron), [Koraput (traditional agriculture), Odisha], and [Kuttanad (below sea-level farming), Kerala].
    • “Globally Important Agricultural Heritage Systems” (GIAHS) are outstanding landscapes of aesthetic beauty that combine agricultural biodiversity, resilient ecosystems, and valuable cultural heritage.
  • In India, over 811 cultivated plants and 902 of their wild relatives have been documented.

Challenges to Agrobiodiversity

  • Loss of crop genetic resources due to adopting new crop varieties without conserving traditional varieties. For example, Bt cotton.
  • Similarly, there are concerns on high output breeds for the production of meat, milk, and eggs. Crossbreeding of foreign breeds with indigenous breeds leads to erosion of genetically diverse pool.
  • Out of 2,50,000 globally identified plant species, about 7,000 have historically been used in human diets.
    • Today, only 30 crops form the basis of the world’s agriculture, and just three species of maize, rice, and wheat supply more than half the world’s daily calories.
