The vast majority of migrants, about 763 million, move within their own countries. Many migrants come from rural areas, where more than 75 per cent of the world’s poor and food insecure depend on agriculture and natural resource-based livelihoods. Their prime motivation is often to escape hardships caused by a variety of factors. Poverty, food insecurity, lack of job opportunities and increased competition for scarce land and water resources lead people to seek an escape. The effects of climate change as well as political conflicts are likely to create further migration pressures both within and across countries.
