High confidence for observed livelihood impacts is spatially concentrated in South Asia, Africa, North America, and to a lesser extent Small Island Developing States  . The hazards most prevalent in all regions include warming trends, droughts and sea level rise , and undermine crop productivity, crop varieties, and cropland in most regions . Along coastlines, climate hazards threaten livelihoods particularly exposed to extreme weather, flooding and sea level rise, and where poor populations are heavily dependent on agriculture and fisheries . One third of total sampled evidence on livelihood impacts was observed in just three countries-Bangladesh, India and Nepal-indicating accumulating experience with livelihood impacts in South Asia . However, this spatial representation of confidence does not mean that observed livelihood impacts are not occurring in other regions as well. Relative to South Asia, in Central Asia and the Caribbean, for example, the weight of evidence of livelihood impacts though lighter is still robust. Among industrialised nations, there is high confidence that climate change has impacted livelihood resources in the USA.
