Testing the ‘Laacher See hypothesis’: a health hazard perspective

It has recently been suggested that the Laacher See volcanic eruption, which occurred around 13,000 years ago, initiated significant demographic fluctuations along the northern periphery of Late Glacial human settlement and that these led to a number of material culture transformations. The origins of the Southern Scandinavian Bromme culture and the northeastern European Perstunian culture as well as the temporary abandonment of Central European regions have been linked to this eruption. However, it remains unclear precisely which aspects of the eruption stimulated Late Glacial foragers to abandon their traditional ways of life. Paradoxically, the culture–historical impact of the eruption appears greater further away from the eruptive centre. Here, we investigate one potential middle-range link between the Laacher See eruption and Late Glacial fauna and foragers: tephra as a health hazard. We use laser-diffraction particle-size analysis to quantitatively investigate tephra from one site with a secure Late Glacial archaeological deposit. In addition, we use values previously reported in the literature and a predictive model to calculate the hazard potential along a transect of two of the three major Laacher See tephra fans. Our results show that the Laacher See tephra may have posed a potential health hazard and that its hazard potential may have increased with distance from the vent. To our knowledge this is the only study that attempts to quantify the changing grain-size composition of tephra fall-out longitudinally in this way, at least with regard to a prehistoric eruption. We close by discussing, more speculatively, other possible health-pertinent effects of the Laacher See eruption and suggest ways in which future work can further evaluate the impact of this eruption on Late Glacial populations.     

Participatory Watershed Development in India: Can it Sustain Rural Livelihoods?

The purpose of this article is to assess the impact of policy interventions through watershed development (WD) on the livelihoods of the rural communities. This is done by assessing the programme in the context of a sustainable rural livelihoods framework, that is, looking at its impact on the five types of capital assets and strategies required for the means of living. The article also examines the vulnerability and stability of these capital assets, as well as analysing which people participate in the programme and enhance their livelihoods through sharing its benefits. In the light of the analysis, it is argued that watershed development holds the potential for enhanced livelihood security even in geo‐climatic conditions where the watershed cannot bring direct irrigation benefits on a large scale. In such fragile environments, however, watershed development is a necessary but not a sufficient condition for sustaining rural livelihoods. While the focus of watershed development is primarily on strengthening the ecological base such as water bodies (including traditional tanks), grazing lands and wastelands, it should be complemented with other programmes which focus on landless poor households in order to make it pro‐poor. In the context of low rainfall regions where improvement in irrigation facilities is slow, agriculture alone cannot support the communities. Policies and programmes should aim at creating an environment for diverse livelihood activities, which are the choice of the household rather than distress activities.
