For example, climate change may alter the frequency or intensity of hazards that threaten the viability of a community's traditional farming or fishing livelihoods. Local farmers or fishers are then forced to adapt how they farm or fish or abandon livelihood practices entirely. The latter may mean migrating to a city to find work. As many communities face the same challenge, this intersects with a global trend that is affecting billions of lives and livelihoods-urbanisation-as seen in the rapid growth of informal settlements at the peripheries of cities around the world, particularly rapidly growing mega-cities in Africa, Asia and Latin America. These developments will be accelerated by negative impacts of climate change and increase risks that larger segments of the population enter conditions of persistent poverty.
