Sustainable management of crop plantations to sequester more carbon is a timely strategy to reduce greenhouse gases, as these have been considered to be potent measures for mitigation of climate change. Oil palm (Elaeis guineensis) is a proven carbon-sequestering perennial crop by biological means, aiding in the mitigation of global warming and climatic fluctuations. The present study was carried out in Serchhip, Mizoram, India from 5th February to 30th March 2021. All major palm plantation sites located within Serchhip were determined in the study. The carbon store was determined from sample plants of three, six, eight, and ten years. This research adopts a destructive approach to estimate the amount of carbon storage. The investigator surveyed the number of trees and the age of the palm trees with the help of farmers. The results indicates that the trunk stores the largest amount of carbon when compared with other plant parts. However, in a three-year plantation, the fronds store more carbon than the trunk. The study reveals that the amount of carbon sequestered by four, six, eight, and ten-year palm trees were 0.045 t, 0.098 t, 0.276 t and 0.539 t respectively. The total sample surveyed was 1015 standing trees from eight locations, and the carbon stock potential accounting all plantations site within Serchhip was estimated to be 345.1 t/yr. Recently, many farmers are planning of giving up oil palm farming and are likely to replace their oil palm fields with other crops. Uprooting, slashing, and burning is the common practice adopted to clear palm trees, which is believed detrimentally to emit tonnes of carbon into the atmosphere. Therefore, the study will be very helpful in decision-making and, consequently selecting a wiser choice for climate change mitigation within Serchhip and, to a larger extent, Mizoram.
The problem of incident plane waves at the interface of micropolar thermoelastic half-space with voids and micropolar elastic half-space with voids has been attempted. The amplitude and energy ratios of various reflected and refracted waves for the incident [Formula: see text]- and [Formula: see text]-waves are obtained with the help of appropriate boundary conditions at the interface. The effect of linear thermal expansion and microinertia on the amplitude and energy ratios due to the incident [Formula: see text]- and [Formula: see text]-waves are discussed. Numerically and analytically, these amplitude and energy ratios are computed to show the effect of linear thermal expansion and microinertia. It is observed that the effect of linear thermal expansion is less for incident [Formula: see text]-wave and the effect of microinertia is less for incident [Formula: see text]-wave.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
