This article argues on the basis of a comparative study in floodplain areas in Cameroon, Tanzania, and Zambia that land tenure issues have to be related to historical institutional changes not only to property rights in land, but also to land related common pool resources. It further outlines that in addition to privatisation of resources, pastoralists face challenges from the fragmentation of cultural landscape ecosystems, which serves to undermine local common property institutions and their reciprocal resource management arrangements that provided resilience in floodplain ecosystems. Colonisation and postcolonial constellations led to a major institutional change from common to state property in African rangelands, and created legal and institutional pluralism which enabled more powerful state and wealthy actors to shop for institutions that suit them best, especially privatisation and open access constellations (Haller 2010). The article argues that it is this institutional change that transformed the previous cultural landscape ecosystems, that conservationists and governments now want to protect by excluding pastoralists. It will analyse how governments and environmentalists increase their bargaining power in order to appropriate these landscapes in the form of land as commons and green grabbing. It will do so by combining a New Institutionalism and Political Ecology approach (NIPE) with Appadurai's notion of scapes (1996) in a way that unpacks power dynamics for legitimacy-based governmentalities that link global and local scales. The article unpacks the idea of ideoscapes and adds a four-step historical phases model to the concept. This illustrates the scapes pastoralists are in (state, neoliberal, neoliberal applied including investment and conservation, and terrorism and control scapes). These scapes provide legitimacy capital for powerful actors, shape platforms for strategic selection of institutions (institution shopping) and act as Anti-Politics Machines (APM).

机构购物和抗灾力抢夺：改变非洲洪泛区湿地的景观并抢占牧民

本文是在喀麦隆，坦桑尼亚和赞比亚的洪泛区进行的一项比较研究的基础上认为，土地使用权问题不仅与土地产权有关，而且与与土地相关的公共共有资源也与历史的制度变迁有关。报告进一步概述，除资源私有化外，牧民还面临着文化景观生态系统破碎化的挑战，这破坏了当地的公共财产机构及其相互提供的资源管理安排，从而为洪泛区生态系统提供了恢复力。殖民化和后殖民星座导致了非洲牧场从普通财产到国有财产的重大制度变迁，并建立了法律和制度上的多元化，使更强大的国家和富裕行为体可以购买最适合他们的机构，尤其是私有化和开放获取体系（Haller，2010年）。文章认为，正是这种制度变迁改变了以前的文化景观生态系统，保护主义者和政府现在希望通过排除牧民来进行保护。它将分析政府和环保主义者如何增加其议价能力，以便以土地为公地和绿色抢夺的形式来适应这些景观。它将通过结合新制度主义和政治生态学方法（NIPE）与Appadurai的“花s”概念（1996）来实现，这种方法为联系全球和地方规模的基于合法性的政府提供了动力动力。本文介绍了ideoscapes的概念，并为该概念添加了四步历史阶段模型。这说明了牧民所处的景观（国家，新自由主义，新自由主义的应用，包括投资和保护，以及恐怖主义和控制景观）。这些景观为强大的参与者提供了合法资本，为机构的战略选择（机构购物）提供了平台，并充当了反政治机器（APM）。
