Ebook "Recarbonization of the biosphere: Ecosystems and the global carbon cycle" increasing amounts of carbon dioxide (CO2) are added to the atmosphere by fossil fuel combustion but the biosphere is a potential C sink. Thus, a comprehensive understanding of C cycling in the biosphere is crucial for identifying and managing biospheric C sinks. Ecosystems with large C stocks which must be protected and sustainably managed are wetlands, peatlands, tropical rainforests, tropical savannas, grasslands, degraded/desertified lands, agricultural lands, and urban lands.

Carbon sequestration is basically the progression of transforming carbon in the air (carbon dioxide or CO2) stored in the soil carbon. Carbon dioxide is taken up with plants through the process of photosynthesis and built-in into living plant material. Agroforestry provides a sole opportunity to combine the double objectives of climate change adaptation and mitigation. It is an attractive alternative for sequestering carbon on agroforestry lands since it can sequester chief amounts of carbon still as leaving the bulk of the land in the production.

One of the largest sinks of organic carbon on the global scale is the organic matter stored in soils, it contains about 1500 Gt C in the top one meter. Changes in the size and the turnover rate of the soil carbon pools could possibly have an effect on the atmospheric CO2 concentration and the global climate. Stabilization of soil organic C (SOC) is pre-requisite for long-term C sequestration to mitigate climate change. Stabilization of SOC means the decrease in the potential loss of organic C by microbial respiration, erosion or leaching.

Soil organic carbon (SOC) pool is the largest among the terrestrial pools. The restoration of SOC pool in arable lands represents a potential sink for atmospheric CO2. The management and enhancement of SOC is important for sustainable agriculture. The cropping system and soil type influence crop biomass under different fertilization. Agriculture acts as both the sink and sources of the greenhouse gases.

The sensitivity of photosynthesis to each of the environmental variables including low water availability, high temperature, is associated with the inevitable rise in atmospheric carbon dioxide. Plant growth responses to the increasing CO2 concentration will not only affect ecosystem productivity in the future, but also the magnitude of C sequestration by plants. The level of CO2 in the atmosphere is rising at an unprecedented rate.

A study was carried out in an adult Oil Palm (Elaeis guineensis) plantation intercropped with cocoa (Theobroma cocoa) grown in sandy loam soil to study the effect of cropping system on above ground carbon sequestration. Non-destructive method for calculating standing biomass of oil palm and cocoa were used. Based on this biomass data carbon stock and CO2 sequestered from the system were estimated.

Global climate change is a change in long term weather pattern that characterised by the region of the world. Human activities, especially the burning of the coal and oil, have warmed the earth by increasing the concentration of the heat trapping gases. The impact of warming can be observed in changing weather patterns. Climate change is already affecting human health, ecosystem. Agroforestry has been recognized as a means to reduce CO2 emissions as well as enhancing carbon sinks.

Increasing carbon dioxide (CO2) content in the atmosphere is the prime cause of global warming. Capturing this CO2 by agro-forestry systems through photosynthetic activity could be one of the ways to reduce its concentration in the atmosphere. Therefore, an attempt was undertaken to fix the atmospheric CO2 employing the mulberry plant as the sink considering its carbon sequestration potential.

A field experiment was conducted with wheat to study the effect of tillage operations on the changes of the CO2- balance and reflection thereof, if any, on the yield of the crop. The organic sources in the form of decomposed paddy straw and farm yard manure (FYM) were applied in soil and the changes of the CO2-in and CO2-out were observed at the conventional (CT) and zero tillage (ZT) practices. The maximum level of CO2-in (914.06 ppm) and CO2-out (859.43 ppm) were recorded under the CT.

The relentlessly increase of atmospheric carbon dioxide (CO2) concentration due to release from different sources leads to global warming and climate change which are a cause for great concern demanding in-depth research on CO2 emission from soil under different forest cover. Forest cover can reverse the increasing CO2 in the atmosphere, thus, contributes to mitigate climate change. Forest stored about half of the organic carbon (C) contained in terrestrial ecosystems. The role of forests has a great impact on the global biogeochemical cycles and in particular, the carbon cycle.

Inducing calcium carbonate precipitation is another important function of urease in nature. The process takes advantage of the supply of carbonate ions derived from urea hydrolysis and of an increase in pH generated by the reaction, effects that in the presence of Ca2+ ions lead to the precipitation of CaCO3.
