Ethnobotany and on farm conservation of cassava (Manihot esculenta Crantz) in small scale agriculture in the State of Mato Grosso, Brazil

Abstract: The present study investigates the role of traditional community Luzia (CL) and the rural settlement "Banco da Terra" (BT) (Mato Grosso State, Brazil) in on farm conservation of cassava, through socioeconomic census, ethnobotanical survey, identification of local varieties and participant observation. In CL was found higher ethnobotanical knowledge, although BT has presented a higher income (39 BT and 30 CL) and diversity (H' = 3.24 BT and 3.01 CL). The low similarity between collections reveal the complementarity of areas in the on farm maintenance of the agrobiodiversity.

摘要：本研究通过社会经济普查、民族植物学调查、本地品种鉴定与参与式观察，探究了巴西马托格罗索州传统社区卢济亚（Luzia, CL）与乡村定居点“班科达泰拉”（Banco da Terra, BT）在木薯农田原位保护中的作用。研究发现，卢济亚社区的民族植物学知识储备更为深厚；尽管班科达泰拉定居点的收入水平更高（BT组为39，CL组为30）且物种多样性更为丰富（BT的香农-威纳指数H'=3.24，CL为3.01）。样本收集物间的相似性极低，这表明两个区域在农业生物多样性的农田维持工作中具有互补性。
