The main models implemented in this regard were based on selective cycles of vegetal exploitation, especially rubber and wood (Pinedo-Vasquez et al 2001), installation of low-income agricultural activities (Becker 1990;Arima et al 2005) and more recently, soybean cultivation (Fearnside 2001).…”

“…As florestas da Amazônia brasileira historicamente receberam modelos produtivos predominantemente voltados para atividades que causam degradação da biodiversidade, não atenderam às necessidades da maioria da população local e são economicamente instáveis (Fearnside 1993, Becker 2001b, Ab'sáber 2004, Murrieta et al 2006. Os principais modelos implementados neste sentido foram baseados em ciclos de exploração vegetal seletiva, especialmente borracha e madeira (Pinedo-Vasquez et al 2001), instalação de atividades agropecuárias de baixo rendimento (Becker 1990, Arima et al 2005) e, mais recentemente, o cultivo de soja (Fearnside 2001).…”
