The Brazilian semi-arid tropics occupies an area of 969,589 km2 that represents 11% of the national territory and the Caatinga is its most representatives Biome with an area of 844.453 km². However, approximately 46% of this area is deforested. The conversion of Caatinga preserved vegetation in degraded areas has contributed to global climatic changes; therefore, a series of scientific research studies has as its objective to quantify the C reservoirs in different semi-arid regions of the world, as well as to identify the factors that control its dynamic. Recently, network research studies for measuring C stock and balance in natural vegetation and disturbed areas, firstly related to livestock and dry land farming that are dominant activities in the region, and secondly related to irrigated agricultural exploitation due to its high impact in the productive system, have been developed. The studies comprise C determination in soil, plant, micro-organism and atmosphere systems, involving C and energy balance and the effect of land use on C stock relations. C stocks in the Brazilian semi-arid tropics varies from 20 to 48.4 t ha-1 at 0-20 cm soil layer, while for the aerial part of natural vegetation the values vary from 1 to 80 mg ha-1. It can be observed, for the same soil and vegetation type, that changes in land use decrease soil C stock and that plant cover management can behave as C source. |
