The proposed U.S.-Brazil planning visit will allow the U.S. PIs Drs. Christopher Steiner and Keshav C. Das (University of Georgia, UGA) to meet with Brazilian collaborators at EMBRAPA (Agricultural Research Agency of Brazil) Drs. Wenceslau Teixeira and Marcos Garcia to plan an interdisciplinary, collaborative research program in agricultural productivity. Deforestation by the use of fire is a major environmental concern for both the world and Brazil. An alternative known as "slash and char" would produce charcoal out of re-growing biomass for soil amelioration purposes instead of conversion to CO2 by fire (slash and burn). Its efficiency has been demonstrated in Brazil by EMBRAPA. The use of charcoal as soil amendment (biochar) would establish a carbon sink and improve sustainability of tropical agriculture. For the planning visit the UGA team will bring its expertise in carbon cycling and transformation while EMBRAPA will provide its ample experience with tropical agriculture and biochar. Because Brazil is a leader in the area of biomass and alternate energy, both sides will benefit much from the successful establishment of research collaborations in agricultural productivity.

建议美国-巴西计划访问将允许美国PI克里斯托弗施泰纳博士和Keshav C。达斯（格鲁吉亚，UGA大学）会见巴西合作者在EMBRAPA（巴西农业研究机构）博士Wenceslau特谢拉和马科斯加西亚计划在农业生产力的跨学科，合作研究计划。 用火砍伐森林是世界和巴西的一个主要环境问题。 一种被称为“刀耕火种”的替代方法将从再生生物质中生产木炭，用于土壤改良目的，而不是通过燃烧（刀耕火种）转化为二氧化碳。 巴西农业研究和开发机构在巴西证明了其效率。 使用木炭作为土壤改良剂（生物炭）将建立碳汇，提高热带农业的可持续性。 对于规划访问UGA团队将带来其在碳循环和转化的专业知识，而EMBRAPA将提供其丰富的经验与热带农业和生物炭。 由于巴西在生物质和替代能源领域处于领先地位，双方将从农业生产力研究合作的成功建立中受益匪浅。
