Poverty in Asia is concentrated in South Asia, where population growth has put pressure on scarce resources and governments have allowed caste discrimination. Education, healthcare, clean water, and sanitation are often inadequate in some Asian countries. Land ownership issues and a historic lack of foreign investment have also encouraged poverty. While some countries like China and South Korea have made progress against poverty, Asia still has many extremely poor people due to factors like the high cost of fertilizers, falling remittances due to the global recession, and declining foreign aid.
