What is Loss and Damage?
The Earth’s climate is becoming increasingly more unpredictable due to climate change. As more severe and frequent disasters and increased heat and sea level rise continue, adverse effects on humans, biodiversity and the built landscape get harder to avoid. Loss and Damage (L&D) incurred due to climate change impacts is closely related to countries’ past development choices and policies, including its adaptation efforts which can dramatically reduce both economic and non-economic L&D. However, even when efforts to reduce vulnerability, enhance resilience and increase adaptive capacity are successfully undertaken, these actions are increasingly becoming insufficient.
When natural or man-made systems are meeting soft or hard adaptation limits it leads to economic and non-economic L&D. In short, L&D can derive from sudden-onset and slow-onset events. The former includes forest fires, heat waves, heavy rainfall, flooding, cyclones and hurricanes. The latter includes sea level rise, ocean acidification, glacial retreat, temperature rise, desertification, biodiversity loss, land degradation and salinization. For both slow- and sudden-onset events, the losses and damages can be categorized as economic and non-economic. Economic losses can be quantifiable losses of property, assets, infrastructure, agricultural production/revenue, goods and services. Non-economic losses include impacts that are not easily quantifiable in economic terms, such as impacts/loss of life, health, biodiversity, ecosystem services, Indigenous knowledge, cultural heritage, and societal/cultural identity.
Parties differentiate between averting, minimizing and addressing L&D. Averting and minimizing focuses to a great degree on preventive and precautionary measures prior to the climate change effects, and overlaps to a great degree with adaptation measures. However, responding or addressing is often understood as measures taken after the climate change event(s) has happened, i.e., ex post. These measures can also be seen as overlapping with post-adaptation measures.
Sometimes, the actions to address L&D will need to be taken in the context of ongoing climate change, such as sea level rise. The distinction is therefore not clear cut.
L&D is unequally distributed, affecting the most vulnerable and least developed countries the worst, many of which have miniscule emissions and have contributed the least to climate change globally. This puts already strained developing countries’ economies worse off and has led the global community to come together under the UN climate negotiations to support these developing countries financially.
