The traditional durable solutions of return, resettlement or local integration – originating in refugee policy, and more recently transposed to internal displacement situations – have long been viewed as standard reference points for resolving displacement. However, the normative basis for durable solutions for internally displaced persons (IDPs) in international law remains under-examined and unclear in many respects, especially regarding the scope and status of relevant rights and obligations and identification of duty-bearers. This provides a relatively weak footing for the legality/normativity of a human rights-based approach to durable solutions, which has been asserted as offering the fairest and most sustainable results.

International legal norms underlying durable solutions for IDPs has mainly been articulated and developed through soft law and regional treaties. Legal research around these instruments has largely focused on their origins, domestication and implementation, while (sparse) research on the normative underpinnings of durable solutions for IDPs has mostly zoomed in on discrete issues around specific solutions, particularly in conflict situations. While research on durable solutions from the field of international refugee law may offer parallels, differences in underlying state responsibilities may complicate extension of its conclusions by analogy.

This paper therefore aims to explore the scope, content and nature of the normative basis for IDP solutions in the perspective of a human rights-based approach via mapping and analysis of primary and secondary doctrinal sources in international human rights law – also drawing on the author’s research on reparation for displacement, and with an emphasis on the contributions of international and regional (quasi-)judicial human rights mechanisms. This analysis will allow for delineation of a number of future research questions on rights and responsibilities in resolving displacement. It may also contribute to discussions on the need for an IDP treaty (and its scope), as well as the development of a distinct body of IDP law.

Dr Deborah Casalin is Principal Research Fellow at the University of Antwerp Faculty of Law – Law and Development Research Group, where she is examining durable solutions for IDPs from a legal perspective. Her doctoral research, defended in 2022 at the same faculty, explores the role of international (quasi-)judicial human rights bodies in ensuring reparation for arbitrary displacement. She is a research affiliate of the RLI Internal Displacement Research Programme.

As climate impacts intensify, planned relocation is increasingly deployed as an adaptation strategy, yet outcomes for relocated communities remain consistently adverse. This paper argues that these failures stem from the treatment of planned relocation as a short-term, projectised disaster response rather than as a long-term developmental intervention. Drawing on social protection theory, this paper reconceptualises planned relocation as a form of social assistance, capable of delivering durable solutions. It demonstrates that planned relocation inherently performs preventive, protective, promotive, and potentially transformative social protection functions by minimising future climate risks, providing non-contributory transfers such as land and housing, and enabling livelihood reconstruction. However, when implemented outside formal social protection systems, these functions may collapse, often resulting in impoverishment and protracted displacement.

Researching Internal Displacement is pleased to make this case study available as a stand-alone publication. Excerpted from a recent research and advocacy report by the Refugee Law Initiative, this case study of an urban informal settlement in Tongi, Bangladesh, examines the lived experience of loss and damage among people displaced in the context of climate change and left behind in climate action. Encouragingly, the case study also highlights a promising 'good practice' development intervention by the SAJIDA Foundation. In the case study, programme participants describe how Sajida’s multifaceted approach, which empowers women and girls, encourages positive behaviour change and prioritises psychosocial wellbeing across multiple programme workstreams, has helped restore agency, self-sufficiency and hope. SAJIDA’s programme shows how protracted displacement and associated losses and damages can be addressed and are not inevitable.

Foregrounding the voices of people living in three different communities of displacement in Bangladesh, this field research and advocacy report examines the nexus of climate change, loss and damage and displacement. This comprehensive report highlights promising interventions by Bangladeshi civil society organisations that have helped internally displaced people (IDPs) living in protracted displacement move toward durable solutions. It also examines positive developments on the policy front, including Bangladesh's fledgling National Strategy on Internal Displacement Management (NSIDM). At the same time, it calls attention to how Bangladesh's protracted displacement crisis remains under acknowledged and therefore under addressed in national policy and programming. The findings and recommendations in this report are intended to inform the UNFCCC's Loss and Damage mechanism – the Fund for Responding to Loss and Damage (FRLD), the Santiago Network for Loss and Damage (SNLD) and the Warsaw International Mechanism (WIM) ExCom, including its Taskforce on Displacement. Each must urgently demonstrate its commitment to addressing the growing displacement crisis and supporting durable solution programming. The report's findings and recommendations are also relevant to intergovernmental, governmental and civil society organisations working in and outside Bangladesh. Furthermore, the report suggests how conventional durable solutions approaches to displacement must evolve to remain relevant in a world of escalating losses and damages resulting from climate change.
