From sex trafficking within escort services to labor trafficking of farmworkers, the ways humans are exploited differ greatly. Each type has unique strategies for recruiting and controlling victims and concealing the crime.

For years, we have been staring at an incomplete chess game, moving pieces without seeing hidden squares or fully understanding the power relationships between players. The Typology of Modern Slavery, our blurry understanding of the scope of the crime is now coming into sharper focus.

Polaris analyzed more than 32,000 cases of human trafficking documented between December 2007 and December 2016 through its operation of the National Human Trafficking Hotline and BeFree Textline—the largest data set on human trafficking in the United States ever compiled and publicly analyzed. Polaris’s research team analyzed the data and developed a classification system that identifies 25 types of human trafficking in the United States. Each has its own business model, trafficker profiles, recruitment strategies, victim profiles, and methods of control that facilitate human trafficking.

Modern slavery is the very antithesis of social justice and sustainable development. The 2021 Global Estimates indicate there are 50 million people in situations of modern slavery on any given day, either forced to work against their will or in a marriage that they were forced into. This number translates to nearly one of every 150 people in the world. The estimates also indicate that situations of modern slavery are by no means transient – entrapment in forced labour can last years, while in most cases forced marriage is a life sentence. And sadly, the situation is not improving. The 2021 Global Estimates show that millions more men, women, and children have been forced to work or marry in the period since the previous estimates were released in 2017.

The 2017 Global Estimates of Modern Slavery focus on two main issues: forced labour and forced marriage. The estimate of forced labour comprises forced labour in the private economy, forced sexual exploitation of adults and commercial sexual exploitation of children, and state-imposed forced labour.

The estimates herein are the result of a collaborative effort between the International Labour Organization (ILO) and the Walk Free Foundation, in partnership with the International Organization for Migration (IOM). They benefited from inputs provided by other UN agencies, in particular the Office of the High Commissioner for Human Rights (OHCHR).

In the context of this report, modern slavery covers a set of specific legal concepts including forced labour, debt bondage, forced marriage, other slavery and slavery like practices, and human trafficking.

Issues of asylum, migration, humanitarian protection and integration/belonging are of growing interest beyond the disciplinary areas of refugee studies, migration, and social policy. Rooted in more than two decades of scholarship, this book uses critical social theory and participatory, biographical and arts based methods with asylum seekers, refugees and emerging communities to explore the dynamics of the asylum-migration-community nexus. It argues that inter-disciplinary analysis is required to deal with the complexity of the issues involved and offers understanding as praxis (purposeful knowledge), drawing upon innovative participatory, arts based, performative and policy relevant research.

Deportation Union provides a critical examination of recently-introduced and forthcoming EU measures designed to increase the number of deportations carried out by national authorities and the European Border and Coast Guard Agency, Frontex. It focuses on three key areas: attempts to reduce or eliminate rights and protections in the law governing deportations; the expansion and interconnection of EU databases and information systems; and the increased budget, powers and personnel awarded to Frontex.

The criminalisation of asylum claimants who arrive with no documentation is the latest salvo in a ‘war on asylum’ which employs every possible method to keep the world’s unwanted masses, the displaced, the desperate and the destitute, away from the shores of Europe – from legal obstacles such as the common visa list,4 imposing impossible visa requirements on nationals of all refugee-producing countries, to British immigration officers stopping Roma passengers boarding aircraft at Prague airport,5 gunboats and military aircraft patrolling the Mediterranean and the coast of west Africa,6 landmines on the Greek border with Turkey7 and the shooting of people attempting to scale the barbed wire fences surrounding the Spanish enclaves of Ceuta and Melilla in Morocco.8 Anything goes, so long as the goal of keeping out poor asylum seekers and migrants is achieved.

This open access monograph provides an overview of the everyday lives of undocumented migrants, thereby focusing on housing, employment, social networks, healthcare, migration trajectories as well as their use of the internet and social media. Although the book’s empirical focus is Finland, the themes connect the latter to broader geographical scales, reaching from global migration issues to the EU asylum policies, including in the post-2015 situations and during the COVID-19 pandemic, as well as from national, political, and societal issues regarding undocumented migrants to the local challenges, opportunities, and practices in municipalities and communities. The book investigates how one becomes an undocumented migrant, sometimes by failing the asylum process. The book also discusses research ethics and provides practical guidelines and reflects on how to conduct quantitative, qualitative, and mixed methods research about undocumented migrants. Finally, the book addresses emerging research topics regarding undocumented migrants.

This book analyzes issues in human rights law from a variety of perspectives by eminent European and Asian professors of constitutional law, international public law, and European Union law. As a result, their contributions collected here illustrate the phenomenon of cross-fertilization not only in Europe (the EU and its member states and the Council of Europe), but also between Europe and Asia. Furthermore, it reveals the influence that national and foreign law, EU law and the European Convention on Human Rights, and European and Asian law exert over one another.

The various chapters cover general fundamental rights and human rights issues in Europe and Asia as well as specific topics regarding the principles of nondiscrimination, women’s rights, the right to freedom of speech in Japan, and China’s Development Banks in Asia.

Protection of human rights should be guaranteed in the international community, and research based on a comparative law approach is useful for the protection of human rights at a higher level. As the product of academic cooperation between ten professors of Japanese, Taiwanese, German, Italian, and Belgian nationalities, this work responds to such needs.

Since the late 1990s, Asian nations have increasingly encouraged, facilitated, or demanded the return of emigrants. In this interdisciplinary collection, distinguished scholars from countries around the world explore the changing relations between nation-states and transnational mobility. Taking into account illegally trafficked migrants, deportees, temporary laborers on short-term contracts, and highly skilled émigrés, the contributors argue that the figure of the returnee energizes and redefines nationalism in an era of increasingly fluid and indeterminate national sovereignty. They acknowledge the diversity, complexity, and instability of reverse migration, while emphasizing its discursive, policy, and political significance at a moment when the tensions between state power and transnational subjects are particularly visible. Taken together, the essays foreground Asia as a useful site for rethinking the intersections of migration, sovereignty, and nationalis.

Two issues come to the fore in current debates over migration: illegal migration and the role of gender in illegal migration. This incisive study combines the two subjects and views the migration scholarship through the lens of the gender perspective, investigating definitions of citizenship and the differences in mechanisms of inclusion and exclusion for men and women, producing a comprehensive account of illegal migration in Germany, the Netherlands, Great Britain, the Soviet Union, Mexico, Malaysia, the Horn of Africa and the Middle East over the nineteenth- and the twentieth centuries.

"This volume, edited by Ignazia Bartholini, principal investigator of the PROVIDE - Proximity on Violence: Defence and Equity project (Rights, Equality and Citizenship Programme - 2014-2020) funded by the EU, shifted the interpretative focus of its research from gender-based to proximity violence. This theoretical intuition-assertion, fruitful too at empirical level, is informed by a wide-scale reconstruction of the phenomenon of migratory violence and corroborated by the results of the action research carried out by six international teams ˗ Ismu, Oxfam, Telefono Donna, Badia Grande, Aseis Lagarto, SamuSocial International, the University of Jaén and the University of Palermo. Systems of protection, formal and informal good practices, as well as critical issues regarding the reception of migrants, are explored and narrated by the co-authors of the volume thanks to the action research they conducted with the collaboration of a plethora of professionals who narrate and illustrate the topic of proximity violence, providing their own particular frames of reference, views and counterfactual reflections. Furthermore, the discussion of legislation provided offers a cogent cross section of what has been done to contrast the violence which thousands of asylum seekers and refugees undergo and how much national governments need to do in order to host and recognise victims of proximity violence."

Navigating Borders into the Netherlands provides a unique in-depth look at human smuggling processes. Based on biographical interviews with smuggled migrants in the Netherlands, the study reveals considerable differences that exist in smuggling's underlying causes, how journeys evolve, and outcomes of the process. This research from an insider's perspective clearly demonstrates that smuggled migrants are not passive actors, there is a broad variety in types of smugglers, and interactions between migrants and smugglers largely determine how the smuggling process evolves.

Trafficking is an emerging concern in West Africa. In 2011, 17 percent of all cocaine consumed in Europe—21 tons—passed through the region, for a retail value of US$1.7 billion. This paper discusses the evolution of trafficking in the region and provides estimates of the size and value of trafficking flows to demonstrate the significance of this illegal activity. Although this topic is gaining increasing attention, less attention has been has been paid to how trafficking is perpetuating fragility. This paper contributes to this area of research by identifying five channels through which trafficking is intensifying fragility in the region. The relative importance of each channel is discussed, with specific countries as case-study examples. Possible programmatic responses are then suggested with examples of policy approaches successfully adopted elsewhere in the world.

The Trump administration has declared war on MS-13, the notoriously brutal gang based in El Salvador. A similar initiative launched by the Bush administration in 2005 stifled the gang's activity after several years, but the gang has been able to rebuild itself here since 2012.

Center researchers reviewed more than 500 cases of MS-13 gang members arrested nationwide since 2012. We conclude that this resurgence represents a very serious threat to public safety in communities where MS-13 has rebuilt itself. The resurgence is directly connected to the illegal arrival and resettlement of more than 300,000 Central American youths and families that has continued unabated for six years, and to a de-prioritization of immigration enforcement in the interior of the country that occurred at the same time.

All criminal gangs are a threat to public safety, but MS-13 is a unique problem because of the unusually brutal crimes its members have committed, its success in using intimidation to victimize and control people in its territory, and its focus on recruiting young members, often in schools.

Nevertheless, because such a large share of MS-13 members are not citizens, they are especially vulnerable to law enforcement, and many can be removed from the communities they terrorize. Strategic use of immigration enforcement is a necessary element to disrupting and dismantling MS-13 gangs and any other transnational criminal organization operating in our communities.

The proliferation of sanctuary policies that interfere with cooperation between state and local law enforcement agencies threatens to hamper efforts to stifle MS-13 activity. The federal government must take steps to clarify how federal law permits such cooperation and also must set up consequences for those jurisdictions and officials who impose sanctuary policies.

Latin America is, by far, the most dangerous region of the world for environmental human rights defenders (EHRDs). The lack of effective guarantees of human rights protection in Latin American States has created this dire situation. The absence of effective safeguards is worsened by the weak rule of law in most Latin American countries, by worrying trends of impunity that corrode the fabric of society, and by the fact that environmental movements usually concern major development projects involving powerful governmental and corporate interests.

This report illustrates the severe human rights violations in Latin America against environmental defenders, who engage in lawful activities that bring to light environmental damage and human rights abuses. Though not exhaustive, this report provides an overview of recent incidents throughout Latin America. The incidents cited cover a range of human rights violations, including violent attacks, torture, disappearances, and killings.

There are two statements that Pope Francis has constantly repeated from the beginning of his Pontificate: that ‘Human Trafficking is Modern Slavery’ and that this practice is a ‘Crime against Humanity’. PASS endorses both without reservation having, in fact, been the first to coin the latter phrase. However, each statement merits closer inspection because they denote rather different issues. Both have been crucial in shaping the leadership that the Catholic Church has assumed and the agenda she has adopted in spearheading a social movement opposing this morally horrendous treatment of human persons. As many social scientists have noted, today’s digital media make initial protests and demonstrations by new social movements easier to organize than ever before. Conversely, to hold a movement together whilst pushing its agenda forward remains as difficult as ever. The latter is where our Academy (in fact, the two Academies) can make a contribution. We are not ‘beyond moral outrage’; that remains our constant bedrock. However, it also requires a clearer definition of what new social provisions are needed not merely to eliminate Human Trafficking quickly but to restore respect – and self-esteem – to those whose human dignity has been assaulted and battered through the process of being trafficked. It is to this that the first statement points unequivocally.

This study shows that migrant smuggling routes affect every part of the world. It is based on an extensive review of existing data and literature. The study presents detailed information about key smuggling routes, such as the magnitude, the profiles of smugglers and smuggled migrants, the modus operandi of smugglers and the risks that smuggled migrants face. It shows that smugglers use land, air and sea routes – and combinations of those – in their quest to profit from people’s desire to improve their lives. Smugglers also expose migrants to a range of risks; violence, theft, exploitation, sexual violence, kidnapping and even death along many routes.
