Background <p>Many of the problems currently facing our societies are long-term. Long-term problems are complex, often large-scale, and may require considerable planning and resources to avert undesirable outcomes in the (far) future. Consider issues such as climate change, nuclear waste disposal, and the sustainable management of ecosystems. The ability of a society to adequately address the most relevant problems depends on appropriate long-term governance, i.e., strategic, consistent, and coherent governance over an extended period of time.</p> Main text <p>Serious obstacles are inherent in long-term governance. These include short election cycles, intergenerational trade-offs, and the uncertainties involved in long-term decision-making. Liberal democracies appear to encounter difficulties in providing adequate responses to pertinent long-term issues, such as climate change, due to the institutions’ current design, which primarily focuses on safeguarding the interests of the present generation.</p> Conclusions <p>This paper introduces long-term governance as a distinct philosophical topic by defining it in relation to a novel perspective on long-term challenges. The paper defends an obligation to engage in long-term governance based on the basic rights of those who do not yet vote. This includes, in particular, an obligation to engage in research into long-term governance institutions.</p>
