According to the Global Humanitarian Overview (GHO) 2023, a record 339 million people will need humanitarian assistance and protection in 2023 – a significant increase from 274 million people a year ago, which was already the highest figure in decades.
The impact of disasters on vulnerable populations threatens to increase humanitarian needs and to reverse progress towards achieving the SDGs. Reducing risks and applying a preventive approach is essential to securing the relief expected from humanitarian interventions.
UNDRR's work to scale up DRR in Humanitarian Action was launched in conjunction with UN Secretary-General Antonio Guterres’ prevention agenda, which called on the United Nations to transcend traditional divides to reduce long-term risks and vulnerability, prevent future crises, build more resilient societies and achieve the Sustainable Development Goals. It also contributes to wider efforts to enhance humanitarian-development-peace collaboration. Priority 4 of the Sendai Framework for Disaster Risk Reduction highlights the need to “link … relief, rehabilitation and development, [and to] use opportunities during the recovery phase to develop capacities that reduce disaster risk in the short, medium and long term.”
As the COVID-19 pandemic has shown us, prevention is always better than cure. In an increasingly connected world, where risks cascade, critical opportunities are being missed to improve how we reduce risk in humanitarian contexts.
Humanitarian assistance costs are predicted to rise to $50bn per year by 2030, on the basis of current trends.

Unless urgent climate and development action is taken, Sub-Saharan Africa, South Asia, and Latin America could be dealing with a combined total of over 140 million internal climate migrants by 2050.

274 million people will need humanitarian assistance and protection in 2022; that's 1 in every 29 people worldwide.
UNDRR helps countries put in place the measures they need to reduce disaster risk and avoid creating new risks. UNDRR supports the scaling up of DRR in humanitarian action in the following ways:
- Convening the multi-stakeholder initiative Scaling up DRR in Humanitarian Action 2.0, including development of a Checklist and Recommendations on Scaling up DRR in Humanitarian Action 2.0 , launched at the Humanitarian Networks and Partnerships Week in May 2021
- Supporting country-level roll-out and application of the Checklist & Recommendations, including pilot testing in collaboration with OCHA in Haiti, Pakistan and South Sudan, with the UN Resident Coordinator’s Office in Bangladesh, and a global review of risk/DRR in 2021 Humanitarian Needs Overviews/Humanitarian Response Plans
- Strengthened partnerships with humanitarian actors to mainstream DRR in humanitarian policies, decisions and guidance, such as the IASC Leadership in Humanitarian Action: Handbook for the UN Resident and Humanitarian Coordinator
- Technical support to enhance the understanding of and knowledge on risk in humanitarian settings through the Global Risk Assessment Framework
- Capacity building activities on DRR and risk with humanitarian partners
- Supporting countries in fragile contexts to develop national DRR strategies, including in conflict and post-conflict countries
- Collecting data on disaster losses through disaster loss databases.
- Advocacy and guidance towards effective financing for pre-emptive actions to reduce disaster risk
- Advocacy and communications on risk prevention and management in humanitarian contexts

Disaster displacement

This Words into Action guide offers practical guidance to help government authorities integrate disaster displacement and other related forms of human mobility into regional, national, sub-national and local DRR strategies in accordance with Target (E) of the Sendai Framework, to revise or develop DRR strategies by 2020. It provides basic background information and highlights the various roles DRR and DRM can play in reducing, preparing for and responding to disaster displacement.
