This study examines the multi-decadal variability and trends of surface air temperature precipitation in 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 Mann–Kendall test (MKT), Sen's Slope Estimator (SSE), Incremental Trend Analysis (ITA) were applied to assess impact temperature, rainfall, number rainy days on yield. The analysis revealed significant decline annual rainfall by approximately 13.62 mm per year, with pronounced seasonal declines 0.87 winter, 12.33 pre-monsoon, 24.93 southwest monsoon, 18.10 post-monsoon. Simultaneously, dropped nearly 19.75 over 40-year period.

Urban plantation dynamics in different topographical and climatic conditions Odisha were evaluated using linear model selection regularisation techniques. The main objective was to evaluate how what extent the urban plantations respond various edaphic conditions. relationship between vegetation growth soil parameters studied four statistical learning tools, subset selection, ridge regression, lasso, partial least squares their performance compared a multiple regression model. test MSE for models be 16,261.54, 12245.11, 16263.79 14,317.21, respectively. Results proved that methods, namely regressions more accurate than regression. From results, it can safely concluded temperature shows greater correlation with parameters. Precipitation also plays vital role dynamics. Soil indicate positive of growth.

Pinus kesiya and Toona ciliata are widely distributed commercially important tree species in Northeast India. However, precise volume estimation is absent; therefore, the of biomass carbon stock these difficult. The present study attempted to bridge this gap by developing non-destructive allometric models for estimating trees. Allometric were developed selecting 46 trees P. 54 T. from different diameter classes covering entire girth range. For study, total height (H), at breast (DBH) various heights both measured. performance was assessed based on coefficient determination (adjusted R2) Akaike's Information Criterion (A.I.C.), besides many other statistics. best-fit model was: lnAGB = −3.7268 + 1.5908 (lnD*H) −2.0311 1.4858 (ln D*H*WD). may be suitable species-specific species. will useful sequestration potential region, which help assessment global cycling.
