In the 2016 Global Education Monitoring Report, the United Nations Educational, Scientific and Cultural Organization alerts us that education "will not deliver its full potential unless participation rates increase and sustainable development guides education system reform." The GEM Report also examines "the destructive impact that climate change, conflict, unsustainable consumption, and the increasing gap between rich and poor have on education."

Despite its 535 pages of UNESCO jargon, the report is rich in evidence. It does, indeed, "provide readers with an authoritative source" of data to help them "argue for the value and importance of education at all levels of decision making." And it starts with the very title: "Education for People and Planet: Creating Sustainable Futures for All." At last, we, the people, are one and the same with Earth.

Here are paraphrased the report's major findings:

— Between 2008 and 2014, 84 percent of the world's youth completed upper secondary school in high-income countries, in contrast to 43 percent in upper-middle income, 38 percent in lower-middle income, and 14 percent in low-income nations. Across 76 countries, 20 percent of the 25- to 29-year-olds in the richest nations had finished at least four years of college/university, compared to less than 1 percent in the poorest. In 2014, 63 percent of countries achieved gender parity in primary education, but only 46 percent in lower-secondary, and 23 percent in upper-secondary schooling.

— Between 2005 and 2015, school facilities in 26 countries were used for military purposes. Among refugees, 50 percent of primary- and 75 percent of secondary-school-aged were out of school.

— From 2005 to 2014, 758 million adults — 114 million aged 15 to 24 — could not read or write a sentence; nearly two-thirds were women. In 2014, 82 percent of the teachers had minimum qualifications to teach in pre-primary, 93 percent in primary, and 91 percent in secondary schools.

— In at least 35 countries, governments spent less than 4 percent of their GDP and less than 15 percent of their total expenditure on education. UNESCO remarks that such investments need to increase at least sixfold to account for the $39 billion annual education finance gap, but in 2014, the levels were 8 percent lower than at their 2010 peak.

Under current trends, primary school completion for all people might be achieved in 2042, lower secondary school in 2059, and upper secondary school in 2084. Note that upper secondary schooling for women in sub-Saharan Africa by 2030 shall lead to 300,000 fewer child deaths per year in 2050. Not only that, upper secondary completion by 2030 in low-income nations shall increase per capita income by 75 percent by 2050, and accelerate poverty reduction — or its elimination — by 10 years.

Prosperous nations have their own problems: 1 in 10 countries in Europe and North America will not achieve universal upper secondary completion by 2030. Why does this matter? The GEM Report responds with cost-benefit projections: a 5 percent increase in male high-school-graduation rate in the United States would add $20 billion to the economy via reduced crime and higher input to the workforce.

And from a humanitarian perspective, providing universal upper secondary schooling to the world by 2030 would prevent 50,000 disaster-related fatalities per decade by 2040-2050. Yes, education saves lives.

For UNESCO, education is the most effective tool for reducing fertility rates. In Madagascar, for example, a single extra year of schooling extends the space between births by 0.5 years. Environmental education correlates with better "green knowledge" and sustainable lifestyles. However, only 73 percent of 78 countries’ curricula mention "sustainable development," 55 percent "ecology," and 47 percent "environmental education." The latter is crucial for disaster preparedness: "If education progress is stalled, it could lead to a 20 percent increase in disaster-related fatalities per decade."

Regarding citizenry involvement in public life, education encourages constructive political participation. In 106 countries, higher levels of education have correlated with peaceful protests (civil disobedience) rather than with chaotic violence. Interestingly, between 1996 and 2010, low literacy in 123 countries was associated with reduced tax revenue. Thus, education motivates civil responsibility.

"A sustainable future is about human dignity, social inclusion and environmental protection. It is a future where economic growth does not exacerbate inequalities but builds prosperity for all" writes Irina Bokova, Director General of UNESCO, in her introduction to the GEM Report. And I am with her: "if done right, education has the power to nurture empowered, reflective, engaged and skilled citizens who can chart the way toward a safer, greener and fairer planet."
