Oil in Venezuela: Triggering Violence or Ensuring Stability? A Context-sensitive Analysis of the Ambivalent Impact of Resource Abundance

This paper studies the causal factors that make the oil-state Venezuela, which is generally characterized by a low level of violence, an outlier among the oil countries as a whole. It applies a newly elaborated “context approach” that systematically considers domestic and international contextual factors. To test the results of the systematic analysis, two periods with a moderate increase in internal violence in Venezuela are subsequently analyzed, in the second part of the paper, from a comparative-historical perspective. The findings demonstrate that oil, in interaction with fluctuating non-resource-specific contextual conditions, has had ambiguous effects: On the one hand, oil has explicitly served as a conflict-reducing and partly democracy-promoting factor, principally through large-scale socioeconomic redistribution, widespread clientelistic structures, and corruption. On the other hand, oil has triggered violence—primarily through socioeconomic causal mechanisms (central keywords: decline of oil abundance and resource management) and secondarily through the long-term degradation of political institutions. While clientelism and corruption initially had a stabilizing effect, in the long run they exacerbated the delegitimization of the traditional political elite. Another crucial finding is that the impact and relative importance of oil with respect to the increase in violence seems to vary significantly depending on the specific subtype of violence.Venezuela, natural resources, oil, political economy, violence, contextual sensitivity

Nigeria: A Prime Example of the Resource Curse? Revisiting the Oil-Violence Link in the Niger Delta

This paper studies the oil-violence link in the Niger Delta, systematically taking into consideration domestic and international contextual factors. The case study, which focuses on explaining the increase in violence since the second half of the 1990s, confirms the differentiated interplay of resource-specific and non-resource-specific causal factors. With regard to the key contextual conditions responsible for violence, the results underline the basic relevance of cultural cleavages and political-institutional and socioeconomic weakness that existed even before the beginning of the “oil era.” Oil has indirectly boosted the risk of violent conflicts through a further distortion of the national economy. Moreover, the transition to democratic rule in 1999 decisively increased the opportunities for violent struggle, in a twofold manner: firstly, through the easing of political repression and, secondly, through the spread of armed youth groups, which have been fostered by corrupt politicians. These incidents imply that violence in the Niger Delta is increasingly driven by the autonomous dynamics of an economy of violence: the involvement of security forces, politicians and (international) businessmen in illegal oil theft helps to explain the perpetuation of the violent conflicts at a low level of intensity.Nigeria, natural resources, oil, political economy, violence, context sensitivity

Gentrification through Green Regeneration? Analyzing the Interaction between Inner-City Green Space Development and Neighborhood Change in the Context of Regrowth: The Case of Lene-Voigt-Park in Leipzig, Eastern Germany

Green regeneration has become a common strategy for improving quality of life in disadvantaged neighborhoods in shrinking cities. The role and function of new green spaces may change, however, when cities experience new growth. Set against this context, this paper analyzes a case study, the Lene-Voigt-Park in Leipzig, which was established on a former brownfield site. Using a combination of methods which include an analysis of housing advertisements and interviews, the paper explores the changing role of the park in the context of urban regeneration after the city’s turn from shrinkage towards new growth. It discusses whether the concept of green gentrification may help to explain this role. As a result of our analysis, we argue that Lene-Voigt-Park has indeed operated as a trigger for structural, social, and symbolic upgrades in the growing city of Leipzig, but only in combination with real estate market developments, which are the main drivers of change. The concept of green gentrification does help to better understand the role of different factors—first and foremost that of green space. We also discovered some specifics of our case that may enrich the green gentrification debate. Leipzig serves as an example for a number of regrowing cities across Europe where green gentrification might represent a challenge.DFG, 414044773, Open Access Publizieren 2019 - 2020 / Technische Universität Berli

Inscribed Radius Bounds for Lower Ricci Bounded Metric Measure Spaces with Mean Convex Boundary

Consider an essentially nonbranching metric measure space with the measure contraction property of Ohta and Sturm, or with a Ricci curvature lower bound in the sense of Lott, Sturm and Villani. We prove a sharp upper bound on the inscribed radius of any subset whose boundary has a suitably signed lower bound on its generalized mean curvature. This provides a nonsmooth analog to a result of Kasue (1983) and Li (2014). We prove a stability statement concerning such bounds and - in the Riemannian curvature-dimension (RCD) setting - characterize the cases of equality
