The sustainable bioeconomy for arid regions (sbar) is a multi-level research project that will cultivate two desert-dwelling crops, guayule and guar, for a sustainable bioeconomy

The energy independence and security act is calling for the production of 36B gallons per year of biofuels by 2022. Combined, guayule (perennial) and guar (annual) feedstocks can provide biomass year round for biofuel production. Both crops are drought and heat tolerant, grow on marginal lands, and provide economic returns. Scale up to profitable production, however, requires feedstock improvements, expansion of cultivation, agronomic knowledge and practices, and economic crop residue utilization.researchers from the university of arizona (UA), bridgestone americas, INC., colorado school of mines (CSM), colorado state university (CSU), new mexico state university (nmsu), and the USDA-ARS will collaborate on research, development, and deployment (RDD) activities to: 1) improve feedstock; 2) produce feedstock in a sustainable manner; 3) understand how conversion to fuel is affected by variable feedstock quality; and 4) enhance transport, techno-economic, and sustainability models to provide a clear path to commercialization. With the assistance of the advisory board, potential partners will be evaluated to scale-up research findings for bagasse conversion and upgrading to jet, biodiesel, and gasoline.sbar will CO-produce biofuels and bioproducts using minimal water and nutrients from guar and guayule crops. To encourage and develop a bioeconomy workforce, the education and extension plan includes collaboration with native nations, small-scale growers, and school districts with high-percentage underserved populations. The SW U.S. Testbed is critical to understanding how to sustain global agriculture in the face of climate variably.expected long-range outcomes include:· improved guayule profitability for simultaneous production of fuel, rubber, and high value products;· developed regional sustainable supply of bagasse for fuel and guar GUM;· expanded production areas in the SW U.S.;· developed and disseminated best practices for growing guayule and guar;· assessment of the local and regional environmental, economic, and social impacts; and & middot; improved bioeconomy-related pipeline for underrepresented youth.
