News:
Study analyzed multiple characteristics of soil (nutrients & micronutrients) while using satellite data for grassland restoration considering ecological value to be primary criterion.
Findings of study:
- Study categorized Banni grassland's restoration zones into five categories.
- 36% of existing grassland area was “highly suitable”, 28 %was “suitable”, 27% was “moderately suitable”, 7% was “marginally suitable” while 2% was “not suitable” for restoration.
- First two categories (Highly suitable and Suitable zones) can be restored easily with adequate water sources (Irrigation or rainwater harvesting).
- “Marginally suitable” and “not suitable” zones can be managed through terracing & fertilization while protecting them from water erosion and salt intrusion.
The Banni grasslands are inhabited by more than 20 ethnic, semi-nomadic communities across 48 hamlets in 19 "panchayats" (a village-level administrative control unit in India) with a population of about 21,338 in 2011-12. Maldhari is the dominant community in the area, raising livestock for their livelihood and having a particular preference for Banni breed.
The Banni area in Kutch region of western India is a typical salt desert area. The usual methods of farming and husbandry are not successful here.
Prosopis juliflora — a non-native and invasive tree species — has encroached over half Banni, one of Asia’s largest grasslands in Gujarat. The tree is harmful to ecology; yet, local communities have over time grown dependent on it for livelihood by, for example, making charcoal and fuelwood.
