This article explores the causes underlying a strong presence of violent non-state actors (VNSAs) in South America. Based on a case study of the border area between Colombia and Venezuela, the research relies on a broad empirical data collected from newspapers, official documents and interviews. The analytical perspective has been grounded on a theoretical framework of four dimensions: (i) funding and illegal activities, (ii) presence in strategic regions, (iii) low state presence and (iv) violence, which identifies different forms of presence of VNSAs. When questioned about how VNSAs create new forms of alternative governance in a territorial space of fragile statehood, the results tend to reveal a context in which state governance seems to overlap the alternative and illegal governance of VNSAs, creating a fragile and hybrid governance in the region.

Do refugee inflows have an effect on state fragility? In this article I examine whether refugee inflows, commonly associated in the literature with economic and cultural pressures, result in a more fragile state by means of increased violent group grievance. Violent group grievance captures a distinct form of intrastate violence, specifically small-scale hate crimes and ethnic group clashes associated with powerlessness and discrimination. The main hypothesis in this paper is that refugee inflows may increase violent group grievance.

I examine the effect of refugee inflows on the level of domestic violent group grievance using quantitative analyses based on original large-N datasets and cross-sectional longitudinal models to fill gaps in the literature on state fragility. This study controls for alternative explanations and covers the time period between 2006 and 2014. The analysis results confirm the main hypothesis of this paper.

To reduce the consumption of firewood for cooking and to realise recycling-driven soil fertility management, three projects in Northwest Tanzania aim to provide the local smallholder community with cooking and sanitation alternatives. The present study proposes an integrated approach to assess the sustainability of the small-scale cooking and sanitation technologies. Based on the multi-criteria decision support approach (MC(D)A), we developed a decision-specific, locally adapted, and participatory assessment tool: the Multi-Criteria Technology Assessment (MCTA). Pre-testing of the tailored tool was set up with representatives of Tanzanian and German partners of case study projects. From a methodological perspective, we conclude that the MCTA uses a set of relevant criteria to realise a transparent and replicable computational Excel-tool. The combination of MC(D)A for structuring the assessment with analytical methods, such as Material Flow Analysis, for describing the performance of alternatives is a promising path for designing integrated approaches to sustainability assessments of technologies. Pre-testing of the tool served as a proof-of-concept for the general design of the method. Future applications and adjustments of the MCTA require the inclusion of end-users, a reasonable and participatory reduction of criteria, and an increase of feedback loops and group discussions between participants and the facilitator to support a common learning about the technologies and thorough understanding of the perspectives of participants.
