This study examines the multi-decadal variability and trends of surface air temperature and precipitation in the Indian Cardamom Hills (ICH), a degraded tropical rainforest area unique for cardamom cultivation. Utilizing observed long-term climatic data (1958-2017), statistical methods such as the Mann-Kendall test (MKT), Sen's Slope Estimator (SSE), and Incremental Trend Analysis (ITA) were applied to assess the impact of surface air temperature, rainfall, and the number of rainy days on cardamom yield. The analysis revealed a significant decline in annual rainfall by approximately 13.

- Indian cardamom, primarily grown in southern India at altitudes between 900 and 1400 meters, has been analyzed for its essential oil composition using gas chromatography-mass spectrometry (GC-MS).
- The study found significant levels of the major monoterpene 1, 8-Cineole, with concentrations between 28.94% and 34.91% in various cardamom varieties, along with other important monoterpenes.
- Additionally, the research identified sesquiterpenes and ester constituents, highlighting α-Terpinyl acetate as the most prominent ester in one variety, marking the first detailed report on the phytochemical profiles of recent Indian cardamom varieties.
