In the concluding part of the study the author highlights Tridosha theory (Three humours) and bioenergy and reviews the whole situation of Ayurveda around the world.
Shrinking arable land due to soil salinization and, depleting fresh water resources pose serious worldwide constraints to crop productivity. A vision of using plant feedstock for biofuel production can only be realized if we can identify alternate species that can be grown on saline soils and therefore, would not compete for the resources required for conventional agriculture. Halophytes have r...
The implications for greenhouse gas emissions of optimizing a slow pyrolysis-based bioenergy system for biochar and energy production rather than solely for energy production were assessed. Scenarios for feedstock production were examined using a life-cycle approach. We considered both purpose grown bioenergy crops (BEC) and the use of crop wastes (CW) as feedstocks. The BEC scenarios involved ...
We present the first assessment of the impact of land use change (LUC) to second-generation (2G) bioenergy crops on ecosystem services (ES) resolved spatially for Great Britain (GB). A systematic approach was used to assess available evidence on the impacts of LUC from arable, semi-improved grassland or woodland/forest, to 2G bioenergy crops, for which a quantitative 'threat matrix' was develop...
1 There is a divergence of views on future bioenergy deployment that is based in disparate epistemic communities. Integrated assessment models (IAMs) project rising deployment of biomass and biofuels in climate change-mitigation scenarios1,2. In contrast, life-cycle assessments (LCAs) and partial equilibrium models of land-use change emphasize high up-front greenhouse-gas emissions from direct ...
This paper examines the possibilities for domestic bioenergy production in Taiwan utilizing set-aside land. Three bioenergy alternatives are examined-pyrolysis-based electricity, conventional bioelectricity and bioethanol. We examine the comparative economics and choice among these alternatives under current Taiwanese agricultural system policies and also under altered energy and greenhouse gas...
Bioenergy cropping systems could help offset greenhouse gas emissions, but quantifying that offset is complex. Bioenergy crops offset carbon dioxide emissions by converting atmospheric CO2 to organic C in crop biomass and soil, but they also emit nitrous oxide and vary in their effects on soil oxidation of methane. Growing the crops requires energy (e.g., to operate farm machinery, produce inpu...
