Contemporary banditry in northwest Nigeria is a multifaceted phenomenon that encompasses a wide spectrum of violence waged by heavily militarised yet loosely organised rural gangs. These groups engage in everything from cattle rustling to kidnapping for ransom and extortion of peasant communities, with bandits becoming important de facto authorities in swathes of rural northwest Nigeria. 

Underpinning the contemporary bandit conflict, we argue, is an ongoing ‘battle for the bush’ — a struggle over land, governance and rural livelihoods. Historically, the bush functioned as a shared space for farmers and pastoralists. However, land use data shows that the expansion of cropland farming has gradually overtaken grazing lands, reducing pastoral mobility and generating increasing conflicts. The state’s failure to mediate these tensions or provide equitable land policies, coupled with the breakdown of traditional conflict resolution mechanisms, has allowed grievances to fester. In response, bandits have violently reclaimed and reshaped the governance of the bush, not only as a refuge but as a domain of coercive rule, imposing levies on farming and controlling access to land and cattle.

We examine the historical drivers of this transformation and analyse how opportunistic criminals and social bandits have evolved into de facto rural rulers. Along the way, the trend of cropland expansion is being reversed. Yet instead of reestablishing a pastoral idyll, banditry is reproducing the very conditions that gave rise to it, further undermining rural livelihoods in the northwest. This has compounded rural poverty and food insecurity while depriving pastoralist youths’ access to government services and education that could provide for a better future. Our analysis implies that the crisis cannot be solved through military interventions alone but requires a rethinking of rural governance.

Community violence intervention street outreach (CVI-SO) is gaining in popularity as a way to prevent gun violence. There is a growing need to better understand these interventions, which starts with documenting their full scope. Analyzing CVI outreach in Chicago from 2017–2023, the researchers find that organizations specialized in long-term mentoring and adjusted services based on participants’ risk levels, providing higher-risk individuals with more frequent and extended support.

Introduction: Community violence intervention street outreach (CVI-SO) strategies are growing in popularity as non-punitive approaches to solving the public health problem of community gun violence. Evidence on the effectiveness of CVI-SO on rates of violence is mixed and faces challenges due to concerns with documentation and data privacy, intentional selection bias in program design, and variation in participant risk and needs. Effective evaluation requires methods that accurately capture the scope and delivery of services, starting with a greater understanding of the services CVI participants receive and how they vary based on individual characteristics.Methods: This study explores the services that participants received from a coalition of Chicago CVI organizations from 2017–2023. Considering administrative and programmatic data from over 4,000 participants’ nearly 200,000 interactions with providers, the researchers examine patterns in demographics, network-based risk factors, and service provision and dosage. They then use descriptive and latent profile analyses to characterize the “typical” participant in Chicago.Results: Results show that CVI work relies heavily on long-term mentoring relationships. Service patterns show that latent groups exist with varying dosage: higher dosage participants with higher risk for gun violence receive more frequent contacts over longer periods, demonstrating how organizations adjust their approach based on participant needs. Profiles that primarily receive behavioral or social supports-related services also emerge.Conclusions: Findings underscore the need for evaluation frameworks that capture both the strategic variation in service delivery and the multiple pathways through which CVI programs influence participant outcomes.Evanston, IL: Northwestern University, Institute for Policy Research, 2025. 36p.

This paper investigates the link between violent crime and immigration using data from Colombian municipalities during the recent episode of immigration from Venezuela. The key finding is that, following the closing and then re-opening of the border in 2016, which precipitated a massive immigration wave, homicides in Colombia increased in areas close to the border with Venezuela. Using information on the nationality of the victim, we find that this increase was driven by homicides involving Venezuelan victims, with no evidence of a statistically significant increase in homicides in which Colombians were victimized. Thus, in contrast to xenophobic fears that migrants might victimize natives, it was migrants, rather than natives, who faced risks associated with immigration. Using arrests data, there is no corresponding increase in arrests for homicides in these areas. Taken together, these results suggest that the increase in homicides close to the border documented here are driven by crimes against migrants and have occurred without a corresponding increase in arrests, suggesting that some of these crimes have gone unsolved.
