In his 2005 work "The End of Poverty", Sachs wrote that "Africa's governance is poor because Africa is poor". According to Sachs, with the right policies and key interventions, extreme poverty—defined as living on less than $1 a day—can be eradicated within 20 years. India and China serve as examples, with the latter lifting 300 million people out of extreme poverty during the last two decades. Sachs has said that a key element to accomplishing this is raising aid from $65 billion in 2002 to $195 billion a year by 2015. He emphasizes the role of geography and climate as much of Africa is landlocked and disease-prone. However, he stresses that these problems can be overcome.
