This paper argues that new land conflict frontiers are emerging in the context of renewable energy production. The novel aspect of these frontiers is a ‘green’ framing of the use of land considered ‘degraded’, expressing it as a climate protection strategy, and consequently causing similar dynamics of conflict in different regions. With reference to political ecology debates on the notion of frontiers, we analyze the social conflicts over palm oil production for biodiesel and wind energy development in Brazil and Mexico, respectively. We show that green narratives, understood as forms of knowledge production concerning the protection of the climate and sustainable development, not only represent legitimization strategies for new land grabs, but also come with their own dynamics of social conflict and their own constellations of actors.

本文认为，在可再生能源生产的背景下，正在出现新的土地冲突前沿。这些领域的新颖之处在于对被视为“退化”的土地的使用的“绿色”框架，将其表示为一种气候保护策略，因此在不同地区造成了类似的冲突动态。参照有关边界概念的政治生态学辩论，我们分别分析了巴西和墨西哥在棕榈油生产用于生物柴油和风能开发方面的社会冲突。我们表明，绿色叙事被理解为与保护气候和可持续发展有关的知识生产形式，不仅代表着新土地抢夺的合法化策略，而且还伴随着他们自己的社会冲突动态和他们自己的行动者群体。
