International society consists of states and the rules and institutions they share. Although international society has become a mundane feature of the world and the principal research focus of International Relations, it has become meaningless. More specifically, the technical rules that determine what states are and how they relate to other features of the world are units of semantic meaning, but their rampant, unprincipled proliferation has corroded their capacity to contain existential meaning. This deterioration is to be deplored because it alienates subjects from each other, it is totalising and excludes alternatives, and it is theoretically irreversible. To connect the two kinds of meaning, the first step is to reconceptualise international society as consisting strictly of constitutive rules whose meaning depends on the context they jointly compose, which implies that these rules can in turn be represented as signs in a semiotic structure. In order to evaluate the capacity of the signs to contain existential meaning, the next step is to adapt Baudrillard’s hierarchical typology of semiotic systems, ranging from the most meaningful systems based on symbolic exchange value to the vapid terminus of hyperreality based on sign value, in which semantic meaning is without value and existential meaning is impossible. The narrative traces the history of the signs of international law from the premodern period, when Christendom was understood as an approximation of the divine kingdom and a vehicle for salvation, to the present postmodern period, in which hundreds of articles of international maritime law make the decision to go to war over isolated rocks intelligible – even rational – and international trade law catalogues potato products to six digits. Three cases in particular exemplify this devolution in international law: the laws determining the territorial sea, the most-favoured national principle of international trade law, and nationality as a normative basis for statehood.
This thesis develops a conceptual framework for a better understanding of the impact of slow-onset climate and environmental changes on human migration in developing countries. Its regional focus is on the West African Sahel, where the majority of the population depends on agriculture and thus is highly vulnerable to environmental changes. Migration from fragile environments is predominantly considered one of several household strategies to adapt to and minimise the risk of environmental stress. Based on qualitative and quantitative data from two selected rural study areas, Bandiagara in Mali and Linguère in Senegal, this thesis analyses the drivers of migration from the two areas.
The findings illustrate that, even though people highly depend on the natural environment, migration motives are manifold and that migration often is not a household strategy to cope with environmental changes. Although environmental conditions shape migration in the region and the migrants’ support is crucial for most households, environmental stress plays a relatively small role as a driver of migration - at least in Mali, where it is considerably less important than in Senegal. On the contrary, migration is often driven by better opportunities elsewhere rather than by livelihood stressors in the home area. Particularly the migration of young people is often an individual rather than a household decision and influenced by individual aspirations, such as aspirations for consumer goods or a better future, rather than by environmental stress.
This thesis claims that research should consider people’s capabilities to migrate or to stay as well as their individual aspirations and preferences - in addition to the household’s needs and the opportunities elsewhere. This is important in order to explain why some people stay in and others migrate from an area affected by environmental stress, though living under similar conditions. Depending on people’s capabilities to choose freely between staying and migrating and their preferences and aspirations for one or the other activity, people can either be “voluntary migrants”, “voluntary non-migrants”, “forced migrants” or “trapped people”.
Moreover, it is important to consider social trends and transformation processes in the analysis of the linkages between environment change and migration. Higher education levels and aspirations to a “modern” lifestyle among young people, for instance, might decrease the impact of environmental factors on migration, despite worsening environmental conditions.
