Recent years have seen a marked drop in detected illegal border crossings into the EU, yet the effectiveness of border policies remains a subject of debate among policymakers and researchers. The numbers alone do not capture the complexity of migration flows or the adaptability of those seeking to enter Europe.
Official figures show that irregular border crossings into the EU have declined sharply since the peak of 2015, when over 1.8 million crossings were recorded. By 2024, this figure had fallen to about 239,000, a 38% drop from the previous year and the lowest since 2021. EU officials and some commentators present these declines as evidence that recent border control measures are working as intended.
These measures include strengthened border checks, digital registration systems, and enhanced cooperation among EU agencies. The introduction of the entry/exit system and the forthcoming Etias authorisation are designed to improve monitoring and security at the external borders. Additionally, the EU has invested in fighting migrant smuggling and improving the efficiency of returns for those found to be in the EU irregularly.
While overall arrivals are down, the picture is less clear when examining specific migration routes. Research highlights that declines are not uniform: for instance, arrivals via the Central Mediterranean route dropped after 2023, but 2024–2025 levels remained higher than in 2019. Meanwhile, the Atlantic route saw decreases only after several years of growth.
Smuggling networks have proven highly adaptable, quickly shifting routes and tactics in response to new restrictions. When one route becomes more difficult, new departure points emerge elsewhere, often exposing migrants to greater risks. This adaptability means that while border controls may reduce flows in one area, they can inadvertently push migration to more dangerous or less monitored routes.
Underlying drivers such as conflict, economic insecurity, and violence remain powerful motivators for irregular migration. Evidence suggests that the assumption migrants will be deterred by stricter border policies underestimates the strength of these push factors. The nationality profiles of recent arrivals reflect ongoing crises in countries like Eritrea, Sudan, and Afghanistan, where legal migration pathways are often unavailable.
Efforts to tackle the root causes of migration—such as development aid and partnerships with countries of origin—are part of the EU’s broader strategy, but their long-term effectiveness is still uncertain. The EU’s reliance on external partnerships has also raised concerns about sustainability and the ethical costs of outsourcing migration control to countries with questionable human rights records.
Although detected fatalities at sea have declined, this does not necessarily mean migration has become safer. Instead, people are often forced onto more perilous and circuitous routes, with deaths and disappearances along land corridors such as the Sahara remaining high. Some incidents, like the discovery of a migrant boat far from Europe’s shores, suggest that fatalities may be displaced rather than reduced.
The EU’s strategy increasingly relies on agreements with non-EU countries to contain migration flows before they reach European borders. While these partnerships can reduce arrivals in the short term, they come with significant financial and political costs. There have been reports of mass round-ups and violence against migrants in partner countries, raising questions about the long-term sustainability and ethical implications of such arrangements.
Moreover, the EU’s proposed budget for migration management is set to triple, with much of the funding directed toward securitisation and externalisation rather than expanding safe and legal migration pathways. Labour migration schemes remain limited and are often used as incentives for cooperation rather than as genuine alternatives for those most in need.
Experts caution against using short-term declines in arrivals as the sole measure of success. The real test for EU migration policy lies in its ability to move beyond reactive containment and develop a sustainable, rights-based approach. This would require balancing border security with credible alternatives to dangerous journeys, including both asylum and labour migration pathways.
The effectiveness of EU border policies is not just a matter of numbers, but of how well they address the root causes and human consequences of migration.
As the EU continues to refine its border policies, the challenge will be to ensure that reductions in irregular entries do not come at the expense of humanitarian principles or simply shift the problem elsewhere. The ongoing debate reflects the complexity of migration itself—shaped by global forces, individual choices, and the unintended consequences of policy.
The next move for policymakers and observers is to scrutinise not only the immediate impact of border controls, but also their long-term effects on migration patterns, human rights, and the EU’s relationships with its neighbours.
Smuggling networks adapt by finding new routes when restrictions increase.
No, underlying drivers like conflict and insecurity still motivate migration.
Not necessarily; fatalities may be displaced to more dangerous routes.
Reports of violence and mass round-ups raise questions about sustainability and ethics.
No, most funding focuses on securitisation and externalisation rather than expanding safe pathways.
