“…Redundancy of key resources and income diversification are crucial elements that maintain resilience while reducing societal vulnerability to climate change and environmental degradation [132]. Loss of redundancy in the life support system may cause major losses of societal resilience.…”

Research on ecosystem and societal response to global environmental change typically considers the effects of shifts in mean climate conditions. There is, however, some evidence of ongoing changes also in the variance of hydrologic and climate fluctuations. A relatively high interannual variability is a distinctive feature of the hydrologic regime of dryland regions, particularly at the desert margins. Hydrologic variability has an important impact on ecosystem dynamics, food security and societal reliance on ecosystem services in water-limited environments. Here, we investigate some of the current patterns of hydrologic variability in drylands around the world and review the major effects of hydrologic fluctuations on ecosystem resilience, maintenance of biodiversity and food security. We show that random hydrologic fluctuations may enhance the resilience of dryland ecosystems by obliterating bistable deterministic behaviours and threshold-like responses to external drivers. Moreover, by increasing biodiversity and the associated ecosystem redundancy, hydrologic variability can indirectly enhance post-disturbance recovery, i.e. ecosystem resilience.

“…Most studies assessed the role of cultural factors such as acculturation or linguistic factors and individual or psychological stressors associated with the migration process (Almeida et al, 2012;Castañeda et al, 2015;Chen et al, 2000;Cheung, 2014;Eitle et al, 2009;Gil et al, 2000;Gordon-Larsen et al, 2003;Lara et al, 2005;Rostila, 2010;Warner et al, M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 5 2010). Yet, as argued elsewhere, research on migration and health may have over-emphasised the role of cultural factors (including, among others, values and beliefs) and it may instead need a better understanding of the role of structural social determinants of health (Castañeda et al, 2015).…”

“…If people leave a place, because their livelihoods have been negatively affected by natural hazards or environmental changes, one might speak of 'environmentally induced migration ' (cf. McLeman & Smit, 2006;Piguet, Pécoud, & de Guchteneire, 2011;Warner, Hamza, Oliver-Smith, Renaud, & Julca, 2010 for an introduction to the debate and its contested terminology). In order to understand migration in the context of climate change, Findlay and Geddes (2011) argued that one should first investigate pre-existing mobility patterns and livelihood systems, and then assess the 'additional burden' that climate-related risks pose for people.…”

This article presents empirical evidence on changing rainfall patterns in Kurigram district in northern Bangladesh, on the local people's perception of these changes, and on their decision to migrate, or not, in order to cope with rainfall variability and food insecurity. Our study was conducted as one of eight case studies within the 'Where the Rain Falls' Project. Taking on a social vulnerability perspective, we show that migration from the region is not driven by climatic changes, but rather by the existing livelihood and labour migration systems. First, there is a distinct seasonality and thus rainfall dependency of rural livelihoods, which makes the rural population sensitive to changing rainfall patterns. Second, rainfall variability and food security are closely intertwined. Third, the distinct rhythm in the labour migration system is largely structured by seasonal hunger (Monga) in northern Bangladesh and by the demand for agricultural labourers and informal workers at the respective destinations. Fourth, persisting local patterns of social inequality shape both people's condition of food security and their decision to migrate for work or not. We conclude that, instead of climate change, social inequality and food insecurity as well as structural economic differences are the strongest drivers of migration inside Bangladesh.
