STRATEGIES FOR BIOFUEL PRODUCTION AND IMPROVEMENT IN DEVELOPING COUNTRIES: PROBLEMS AND PROSPECTS. A. Kumar Energy Plantation Demonstration project and Biotechnology Center. Bio-Technology Lab Department of Botany University of Rajasthan, Jaipur - 302 004 Email. msku31@yahoo.com ABSTRACT: A large number of hydrocarbon yielding plants like Calotropis procera, Euphorbia antisyphilitica have been reported to yield bio-fuel products. Attempts have been made to increase their growth and hydrocarbon yield potential. Studies were conducted to improve growth and productivity of these plants under field conditions In Rajasthan, Calotropis procera grows wild while Euphorbia antisyphilitica has been introduced from Mexico. Jatropha grows wild in south east

Genetically modified foods (GM foods or GMF) offer a way to quickly improve crop characteristics such as yield, pest resistance, or herbicide tolerance, often to a degree not possible with traditional methods. Further, GM crops can be manipulated to produce completely artificial substances, from the precursors to plastics to consumable vaccines.

PRODUCTIVTY OF CALOTROPIS PROCERA IN SEMI-ARID REGIONS OF RAJASTHAN AND ITS USE AS RENEWABLE SOURCE OF ENERGY Ashwani Kumar, V.R. Kumar Energy Plantation Demonstration project and Biotechnology Center. Department of Botany, University of Rajasthan, Jaipur – 302004, India. E-mail: msku31@yahoo.com ABSTRACT India has over 180 million of wasteland out of which 90 million ha is uncultivable. The degraded and denuded lands arise due to soil erosions as well as secondary salinizations. However Calotropis procera is a potential plant for bioenergy and biofuel production in semi arid regions of the country because it is able to grow on such lands. The plant has a growth potential of 2 dry tones

Liquid biofuel support program launched in 1993 in France is implemented through tax exemptions to biofuels produced by agroindustrial chains. Activity levels are fixed by decree and allocated by the government to the different chains. Based on earmarked budget increase voted in the parliament, total quantity of biofuels will be increased by 50% in the horizon 2002–2003. A microeconomic biofuel activity model containing a detailed agricultural sector component, that is represented by 700 farms, is used to estimate costs and surpluses generated by the activity at the national level as well as tax exemption levels. Furthermore, Monte Carlo simulation has been used to search for efficient tax exemptions policies in an uncertain environment, where biofuel profitability is
