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.
About Banni Grassland (Kutch, Gujarat)
- Asia’s largest tropical grassland spans over 2,600 sq. km. It emerged from sea due to tectonic activities.
- Flora and Fauna: Banni buffalo, Kankrej Cattle, Asiatic wild ass, Camel, and horse etc.
- Cultural significance: Home to more than 20 ethnic semi-nomadic communities. E.g. Maldharis (silvipastoralists), Jats etc.
- Provide ecosystem services e.g. carbon storage, climate mitigation, pollination etc.
- Strange dancing light phenomena (Chir Batti or Ghost lights) occur here at night.
Threats faced by Banni Grasslands
- Excessive pressure from livestock grazing
- Increased soil salinity leading to invasion of Prosopis juliflora
- Water scarcity(aridity), climate change and desertification
