Estimativa de sequestro de carbono de uma árvore nativa com uma exótica no semiárido.

Abstract

In recent decades, there has been a considerable increase in concern about rising temperatures and climate change on the planet, due to increased greenhouse gas emissions in the atmosphere, most of which are CO2, methane and nitrous oxide. Attributed to anthropogenic activities such as industry, the burning of fossil fuels, deforestation, agriculture, livestock and energy generation and consumption. Due to these environmental concerns the work consists in estimating carbon sequestration between two tree species, one exotic, the Moringa oleifera Lam from India, and the other an endemic one from the northeast region of Brazil, the rigid Licania Benth, popular Oiticica, related To determine which one has the greatest potential for carbon sequestration. The study was carried out on the campus of CCTA / UFCG - Pombal / PB, and was developed with the aid of the carbon dioxide, temperature and humidity measuring equipment, and was evaluated in three measurement points, the first in Moringa oleifera Lam, the second Located behind the library to serve as a control point, and the third in Oiticica, measurements occurred during three periods of the day, three conditions of time, and in two periods of the year. The work concluded greater carbon sequestration efficiency in the early afternoon between 12:00 and 13:00 hours, in the exotic arboreal olive moringa species, with cloudy weather conditions, having a more efficient result in the dry season.
