Abstract:Poverty eradication is one of the sustainable human development goals, and is also the important index of human social progress. The study investigates the evolution process of the world poverty and points out the spatial-temporal uneven pattern of the world poverty reduction. The current challenges to the world poverty reduction include aggravated resources exploitation in SubSaharan Africa, worldwide forcibly displaced people who lower down poverty identification accuracy, and rural decline which leads to instable poverty reduction. Oriented by the UN's poverty eradication goal by 2030, the study proposes to strengthen worldwide poverty reduction collaboration, to promote national and regional development transformation, and to revitalize the world's countryside, so as to support world poverty reduction.
