Climate change has emerged as a major man-made global environmental problem, characterized by an increase in the earth's air temperature as a result of large-scale emissions of greenhouse gases. Agriculture and climate change are intrinsically linked in different ways, since biotic and abiotic stresses are primarily caused by climate change, all these factors have a detrimental effect on a region's agriculture. Agriculture is affected by climate change in various ways, e.g., heat stress at the reproductive stage, shortening of growing season length, pests or microbes, modification in weeds, and increase in CO2 level. The challenge of changing global climate has driven the scientists' interest, As a result of these changes, global crop production is suffering and global food security is in danger. The current study sheds light on the impacts of climate change on agriculture, as well as the consequences for food security.

Background: Manganese (Mn) being one of the micronutrients available in acid soils acts crucial role in crop plants. In Assam soil, its concentration is 3-52 ppm whereas in plants the critical limit is 2-3ppm. Although the effects Mn on plants have been well documented, information on its impacts on yield and yield components in upland rice crop grown in Assam was scanty, and deserved its investigation. Method: A pot experiment was carried out to study the effects of Mn (0, 10,20,30 ppm Mn as MnSO4H2O) foliar spray (each 1000cm3) at vegetative stage i.e.70days after sowing, on yield and yield components of ten rice genotypes (Kanaklata, Mulagabharu, Kapilee, Disang, Kolong, Joymoti, Jyoti Prasad, Luit, Lachit and Chilarai) cultivated in Assam. Conclusion: The lower dose of Mn (10ppm) significantly increased panicle length (16.29-37.46%), panicle weight (10.54-19.50%), panicle number per plant (4.54-13.63%), number of seeds per panicle (18.38-36.48%), test weight (7.21-29.15%), high density grains (5.59-30.45%), economic yield (14.40-28.03%), biological yield (32.58-47.70%), and harvest index (3.2-7.90%). 30ppm Mn affected adversely all the physiological attributes in the study. Among the ten genotypes, Kanaklata performed the best followed by Chilarai in the experiment.

The increase in production of greenhouse gases is a major cause of global warming for which livestock holds a big share in total greenhouse gas emission annually. The greenhouse gases produced by livestock include carbon dioxide, methane, nitrous oxide etc. Cattle and buffalo are the major contributors responsible for 90% emission of GHG followed by sheep and goat. Increase in carbon dioxide emission by livestock, decaying of dung in absence of oxygen, enteric fermentations are the major sources of greenhouse gas production by livestock species. Owing to greenhouse effect, the elevated greenhouse gases cause global warming resulting in the increase of surface temperature of earth, decreased precipitation, and huge damage to environment and affect the flora and fauna turning the conditions on earth unfavorable for survival of living forms. The major impacts are loss of biodiversity, loss of habitat for animals and plants, uncertainty in climate, increase in livestock diseases, damage to feed sources (plants), decrease in productivity of livestock species and many more. Mitigation measures needed to be focused on decreasing the global meat consumption, implementing carbon tax, feeding dietary oils/nitrates, manure management and its biodigestion, genetic manipulations besides strengthening of global livestock environmental assessment models.

The genetic components of variation were determined for 12 characters viz., days to 50% flowering, days to 50% boll opening, plant height (cm), number of monopodia per plant, number of sympodia per plant, number of bolls per plant, boll weight (g), seed cotton yield per plant (g), ginning percentage (%), seed index (g), lint index (g) and oil percentage (%).The estimate of the components of variation revealed significant results for both additive (D) as well as dominance effects (H1 and H2) for all the characters except plant height non-significant H2 component, but in majority of traits (except plant height, lint index) H1 was higher than D indicating dominance components were important in the inheritance of seed cotton yield and its components. The average degree of dominance (H1/D)1/2 was found to be more than unity for all the traits (except plant height, number of monopodia per plant and lint index indicating partial dominance) indicating over dominance. Asymmetrical distribution of positive and negative genes in the parents was observed for all the traits. High estimates of heritability in narrow sense was observed for days to 50% flowering, days to 50 % boll bursting, number of monopodia per plant, ginning percentage (%), lint index (g) and oil content (%) suggesting that selection based on these attribute would lead to rapid improvement. Due to preponderance of non-additive gene effects of seed cotton yield per plant and most of its component traits, heterosis breeding would also be practically feasible in cotton.
