Factors behind an increase in CO2 emissions and concentrations include deforestation and a spreading of arid/wasteland areas. Thus, to forestall global warming, it is very important to not only suppress emissions from the combustion of fossil fuels, but also to brake these factors, repair the damage they have done, and plant new forests. In this research, we turn our attention to arid land (parched land that is largely unsuited for even foodstuff production) or, more specifically, to afforestation as a mean to capture/fix carbon dioxide, an approach well suited to the situation at hand. First, toward the development and wide application of afforestation technologies for arid land, we examine and arrange the results of experiments with solid improvement. We next evaluate the carbon-capture ability of such technologies and their potential for practical application. Then, with an eye toward the fabrication of a large-scale biomass utilization system to follow on large-scale afforestation, we are to assemble/assess scenarios for the optimal energy conversion of biomass, together with its market transport and end utilization. While this research is now centered on an area in Western Australia roughly 600mn ENE of Perth, we hope to apply the developed technology to other regions as well.
