By Magdalena Mis LONDON (Thomson Reuters Foundation) – Investing up to 3.5 percent of a nation’s gross domestic product (GDP) in science, technology and innovation can be “the game changer” for development, leading experts said on Thursday. Science, technology and innovation (STI) can help alleviate poverty, reduce inequalities, increase income and improve health, scientists advising U.N. Secretary-General Ban Ki-moon on sustainable development said. “If countries wish to break the poverty cycle and achieve post-2015 Sustainable Development Goals, they will have to set up ambitious national minimum target investments for STI,” the 26-member Scientific Advisory Board said.
