If the pledges of $26 billion per year in new aid are fulfilled, that would amount to $260 billion over a decade.
The number of child deaths due to preventable causes is about 5 million a year in developing countries, or 50 million per decade. If $80 billion of the new aid aims to prevent child deaths, and if a third of such deaths can be prevented for $500 each, and the next third for $2000 each, and the last third for $10,000 each, then the aid may reduce deaths by 38 million over a decade. The number of life-years lost per child death is about 50 years, for a total saving of 1.9 billion life-years.
If another $80 billion in new aid is aimed at adult health, such as AIDS, malaria, and TB, and if death prevention costs $4000 each, then the aid may reduce adult deaths by 20 million over a decade. The number of life-years lost per adult death is about 25 years, for a total saving of 500 million life-years.
The number of children missing school is about 100 million. The equivalent life-years lost by missing school may be 2 years, for a total of 200 million life-years. If $20 billion of new aid supports primary education, and if $100 can pay for one year of school, then all children for whom money is an obstacle, say half, could attend school, for a saving of 100 million life-years.
There are about 1.1 billion people in absolute poverty. If the remaining $80 billion of new aid is aimed against poverty, and if a third of such poverty can be eliminated for $500 per person, then 160 million people can be removed from absolute poverty. The equivalent life-years lost by living in absolute poverty may be about 15 years, giving a total of 240 million life-years saved.
Thus, there could be 2.7 billion life-years / 40,000 life-years/character = 68,000 characters. The article has 5900 characters, thus there is potential for many more articles on these subjects.
