A First for Latin America
Colombia Legally Recognizes "Climate-Driven Forced Displacement"

← Back to Latin America News

In June this year, Colombia enacted Law 2577 of 2026 (Ley 2577). It recognizes climate change, environmental degradation and natural disasters as formal causes of internal forced displacement under the law. It is the first legislation of its kind in Latin America, and there are almost no precedents worldwide. Until now, the concepts of "refugee" and "internally displaced person (IDP)" have been tied to armed conflict and persecution; this law reframes internal movement driven by natural and environmental factors as a legal category of its own.

What happened

The law obliges the government to create a "unified registry of environmental migrants." It further orders the environmental, meteorological and disaster-management authorities to work jointly to draw up, within six months, the criteria for what counts as "climate displacement." Once the criteria are established, people forced to move by environmental factors may become eligible to apply for support and compensation.

Behind the law are pressing numbers. In the first months of 2026 alone, the number of people internally displaced by environmental factors exceeded 25,000. Those most affected are Indigenous communities and Afro-Colombian residents. Colombia, which spans the Andes, the Amazon basin and the Pacific coast, is ecologically diverse — and for that very reason the impact of floods, droughts and landslides is many-sided, and their frequency is rising year by year.

Context: the legal vacuum around "climate refugees"

Until now, there have been almost no examples anywhere in the world of domestic law defining migration caused by climate change. Internationally, the debate has dragged on without settling the legal status of "climate refugees," and the Refugee Convention (1951) does not make climate-driven movement grounds for refugee status. If you do not cross a border you are not a refugee, and if the cause is not conflict you fit awkwardly into the IDP framework. People driven from their homes by the climate have been falling through the gaps of the existing protection systems. In June, the Carnegie Endowment for International Peace described the law as one that "can be a model for the world."

The question: will the registry be a remedy or a dividing line?

At the same time, the challenges are clear. First, the ambiguity of the definition. People who flee for compound reasons — "climate" and "conflict" intertwined — are not rare in today's Colombia. A family that left its village under pressure from armed groups compounded by flooding: which registry do they go on? Rush the line-drawing, and people will fall outside the scope of protection.

Second, the politics of implementation. The incoming De la Espriella administration, which takes office in August, has set a course that prioritizes economic growth, and its stance toward environmental regulation and the legislation of the Petro era is an unknown. The risk that the legal framework runs ahead while budgets and implementation structures fail to follow is, in Colombia's institutional history, not an unusual story.

My perspective

Seen from the standpoint of someone who has researched social security systems, the core of this law lies in a seemingly unglamorous mechanism: the registry. Protection by an institution begins with the person being "visible" to that institution. It is the same with Japan's disability certificates or its disaster-victim rosters — someone who is not registered is, no matter how much they are struggling, treated as if they did not exist as far as the system is concerned. Counting the people driven from their homes by the climate, and registering them as beings with names, is in itself the first step that creates the precondition for support.

That said, a registry is also a double-edged sword. If the criteria are too strict it becomes an instrument of exclusion; too loose, and the finances cannot bear it. Which way will the definition of "climate displacement," to be drawn up within six months, tip? Whether this law becomes a model for the world will be decided not by its text but by how it is operated. Having seen disability certification systems in a number of countries, that is something I can say with confidence.

Glossary

desplazamiento forzado = forced displacement. In Colombia, a term long used in the context of armed conflict. desplazado climático = a climate-displaced person; a concept that begins to take on legal contours with this law. registro único = unified registry; the roster that becomes the gateway to support and compensation.

Whether the reason for leaving is a gun or a flood, the suffering of those driven from home is the same. Colombia has become the first country to recognize that reality in law.
