Unique Identity of Appemidi Mango
Appemidi Mango Under Climate Stress in Western Ghats: The Appemidi mango is an indigenous variety found in Karnataka, valued for its distinct flavour and traditional use in pickles. It received the Geographical Indication (GI) tag in 2009, recognizing its regional uniqueness.
This mango grows naturally in the Aghanashini Valley, part of the ecologically rich Western Ghats. The variety is not widely cultivated commercially, making it dependent on its natural habitat.
Static GK fact: The Western Ghats is one of the eight biodiversity hotspots in the world.
Field Observations and Padayatra Findings
A group of conservationists undertook a 30-km padayatra from Sarakuli to Unchalli Falls between March 30 and April 1. Their study highlighted a decline in tree health and reduced fruit yield.
Farmers reported that erratic climatic conditions are affecting growth cycles. Areas with minimal human disturbance showed relatively better tree density, indicating ecological sensitivity.
Climate Change and Rainfall Variations
Experts identified changes in rainfall patterns as a major threat. Earlier, rainfall was evenly distributed, ensuring effective rainfall, which supports soil moisture and plant growth.
Recent trends show intense rainfall in short durations, reducing water absorption by soil. Combined with rising temperatures, this disrupts flowering and fruiting cycles of the Appemidi trees.
Static GK Tip: Effective rainfall refers to rainfall that is properly absorbed by soil and available for plant use.
Importance of In-situ Conservation
Ecologists emphasize in-situ conservation, which means protecting species within their natural environment. This approach is essential for maintaining the ecological balance required for Appemidi mango survival.
Attempts at ex-situ conservation, such as grafting and plantation outside the native region, have shown limited success. The unique combination of soil, climate, and biodiversity in the valley cannot be easily replicated.
Threat to Genetic Diversity
Researchers have identified 33 distinct Appemidi accessions, many of which are now under threat. Some traditional varieties have already disappeared due to environmental stress.
Conservationists warn that commercial cultivation alone cannot preserve genetic diversity. Protecting the entire ecosystem is necessary to safeguard these unique varieties.
Static GK fact: India has over 300 registered GI products, highlighting its rich cultural and agricultural diversity.
Way Forward
Efforts are ongoing to declare the region as a biodiversity heritage site, which would ensure long-term protection. Sustainable conservation strategies and community participation are essential.
Strengthening awareness and promoting eco-sensitive policies can help preserve both the species and its cultural significance.
