Much of the literature on climate change adaptation claims the destabilizing consequences of environmental crises are mitigated by sociopolitical conditions that influence a state's susceptibility to scarcity-induced violence. However, few cross-national studies provide evidence of conditional scarcity-conflict relationships. This analysis of drought severity and civil conflict onset in sub-Saharan Africa (1962–2006) uncovers three sociopolitical conditions that influence the link between environmental scarcity and civil conflict: social vulnerability, state capacity, and unequal distribution of resources. Surprisingly, we find drought does not exacerbate the high risk of conflict in the vulnerable, incapable, and unequal states thought to be especially susceptible to increased scarcity. Instead, drought negates the peace-favoring attributes of stable states with less vulnerable populations. During severe drought, states with sociopolitical conditions that would otherwise favor peace are no less likely to suffer conflict than states with sociopolitical conditions that would otherwise increase the risk of violence. These findings, which are robust across several measures of these sociopolitical concepts, suggest environmental scarcity is most likely to increase the risk of conflict where populations have more to lose relative to periods with more favorable weather.

Recent studies suggest that the pervasive impacts on global fishery resources caused by stressors such as overfishing and climate change could dramatically increase the likelihood of fishery conflict. However, existing projections do not consider wider economic, social, or political trends when assessing the likelihood of, and influences on, future conflict trajectories. In this paper, we build four future fishery conflict scenarios by considering multiple fishery conflict drivers derived from an expert workshop, a longitudinal database of international fishery conflict, secondary data on conflict driver trends, and regional expert reviews. The scenarios take place between the years 2030 and 2060 in the North-East Atlantic ("scramble for the Atlantic"), the East China Sea ("the remodeled empire"), the coast of West Africa ("oceanic decolonization"), and the Arctic ("polar renaissance"). The scenarios explore the implications of ongoing trends in conflict-prone regions of the world and function as accessible, science-based communication tools that can help foster anticipatory governance capacity in the pursuit of future ocean security.

AbstractRegulatory agencies have long adopted a three‐tier framework for risk assessment. We build on this structure to propose a tiered approach for resilience assessment that can be integrated into the existing regulatory processes. Comprehensive approaches to assessing resilience at appropriate and operational scales, reconciling analytical complexity as needed with stakeholder needs and resources available, and ultimately creating actionable recommendations to enhance resilience are still lacking. Our proposed framework consists of tiers by which analysts can select resilience assessment and decision support tools to inform associated management actions relative to the scope and urgency of the risk and the capacity of resource managers to improve system resilience. The resilience management framework proposed is not intended to supplant either risk management or the many existing efforts of resilience quantification method development, but instead provide a guide to selecting tools that are appropriate for the given analytic need. The goal of this tiered approach is to intentionally parallel the tiered approach used in regulatory contexts so that resilience assessment might be more easily and quickly integrated into existing structures and with existing policies.
