There is a growing scientific debate regarding the suitability of certain modes of governance for promoting sustainable development (SD). However, thus far there is neither agreement on ways to meaningfully distinguish and understand governance modes nor a foundation of the aspects to be chosen for this endeavour. In order to overcome this conceptual vagueness, this paper presents a meta-framework for a sound conceptualization of governance modes. Founded on a reinterpretation of the discourse ‘from government to governance’, we argue that only a multi-dimensional approach giving consideration to political processes (politics), institutional structures (polity) and policy content (policy) adequately captures the complexity of governance phenomena. We furthermore highlight possible key features for exploring these dimensions and compare three recently published frameworks for modes of governance. By offering a sound conceptual clarification of governance modes, we facilitate both their meaningful differentiation and a more systematic understanding of their inherent complexity. In so doing, we inform both theoretical and empirical research on governance for SD. We pave the way not only for making more differentiated theoretical statements on the relationship between governance modes and SD but also for empirically exploring this relationship on a profound basis.

The extractable ores of the world's geologically scarcest mineral resources (e.g. antimony, molybdenum and zinc) may be exhausted within several decades to a century, if their extraction continues to increase. This paper explores the likelihood that these scarce mineral resources can be conserved in time for future generations without intervening but instead simply relying on the price mechanism of the free market system. First we discuss the role of geological scarcity in the long-term price development of mineral resources. Then, to see whether geological scarcity affects the price of minerals we compare the historical trends in the prices of geologically scarce mineral resources with those of geologically more abundant mineral resources. The results show that in the period 1900–2013 the price mechanism did not result in high prices that provide advance warning of exhaustion of minerals. We therefore argue that if conservation is left to market forces, it is not certain that geologically scarce minerals will be timely, automatically, and sufficiently conserved for future generations. We recommend preparing international policy measures targeted at a price increase of the scarcest mineral resources, in order to accelerate substitution and recycling of these materials and help save the geologically scarcest mineral resources for future generations
