All African countries spend less than 1 percent of their gross domestic product on research and development, despite a growing trend of scientists, according to UNESCO’s latest science report. The report, “The Race against Time for Smarter Development” stresses the need for increased investment in science especially in the face of the growing crisis, in order to make science less unequal and more open to all communities. While launching the report last week, officials said that current challenges such as climate change, biodiversity loss, a decline in ocean health and pandemics, are all global concerns that push for mobilizing scientists and researchers from all over the world. According to Shamila Nair-Bedouelle, UNESCO’s Deputy Director-General for natural sciences, only 32 countries in the world raised their research spending by 0.1% or more of their countrys GDPs during that period. Low spending on scientific research was pervasive in Africa, as all countries on the continent were among the 80% of countries worldwide that invested less than 1% of GDP in scientific research. Africa’s share of global expenditure on research and development remained constant at 1.01% between 2014 and 2018 but, in Sub-Saharan Africa, it dropped from 0.44% to 0.42%. Even then, on average, investment in research and development as a share of GDP in Sub-Saharan Africa rose from 0.49% in 2014 to 0.51%, an insignificant increase of 0.02 percentage points. Researchers UNESCO noted the pool of researchers per million inhabitants grew by 13.7% during the same period, an increase that was about three times faster than the global population growth of 4.6%. According to the report, this translated into 8,854 million full-time researchers, a surge that was highly dominated by China, whose researcher pool grew by 11.5% between 2014 and 2018. “On average, expenditure per researcher globally increased by 1.6%,” said Susan Schneegans, the editor-in-chief of the UNESCO science report series, during the launching of the latest report. In terms of global shares of researchers by region, Sub-Saharan Africa had increased its stake from 0.6% in 2014 to 0.7% in 2018, representing a density of 124 researchers per million inhabitants in 2018, up from 102 in 2014. But, despite the small global share, the report highlighted several African countries that were among 38 countries in the world that had increased their researcher density per million inhabitants by more than 15% between 2015 and 2018. Publishing Global trends in scientific publishing were heavily dominated by high-income and upper middle-income countries, while Africa’s global share of scientific publications rose marginally from 2.81% in 2015 to 3.5% in 2019. During the same period, Sub-Saharan Africa’s global share of scientific publications also increased, albeit a much smaller growth, from 1.41% in 2015 to 1.8% in 2019. Whereas the total volume of global scientific publications rose from 1.5 million to 1.7 million between 2015 and 2019, Africa’s contribution also increased from 61,236 to 92,133 publications, while Sub-Saharan Africa’s quota increased from 30,805 to 47,374 publications during that period. What this means is that, although there are indicators in the report that scientific research in the world today is a landscape of economic and academic power, there has been progress in Africa, especially in the increase of publications in niche areas such artificial intelligence and robotics, materials science, energy, biotechnology, nanoscience and electronics. Research topics According to Erika Kraemer-Mbula, a professor of economics at the University of Johannesburg and a member of the team that produced the UNESCO Science Report 2021, between 2012 and 2019, Sub-Saharan Africa more than spiked its research output in artificial intelligence and robotics. South Africa with 3,774 publications, Nigeria (1,600), Ethiopia (305) and Ghana (231) contributed more than 50% of Sub-Saharan Africa’s total output on artificial intelligence and robotics in that period. Several countries in the region have made significant progress in the publication of scientific research, with Cameroon cited as having made strides in energy research, while Kenya has contributed 10% of Sub-Saharan Africa’s publications in animal and plant biology. According to Dr Tiffany Straza, the statistician for the report, there had been a surge in research output on climate-ready crops in Ethiopia, Ghana, Kenya, Mali, Mozambique and Senegal. “Research on climate-ready crops make up one of the fastest-growing research topics for Sub-Saharan Africa and take the lead among topics with at least 100 publications,” said Straza. Other topics of special interest in Sub-Saharan Africa, with at least 100 publications between 2011 and 2019, included greater battery efficiency, eco-construction materials, smart-grid technologies, traditional knowledge, minimising poaching and trafficking of protected species, Human Immunodeficiency Virus and tropical communicable diseases. UNESCO attributed the emerging progress of scientific output in Sub-Saharan Africa to the 22 World Bank-supported centres of excellence that had started turning out high-quality graduates where, so far, more than 21,000 students have enrolled in programmes. Although rising isolationism in global politics was highlighted as reducing traditional sponsorship of training and education programmes in Africa from developed countries, UNESCO noted that some African countries are already getting signals that they should be more proactive in funding capacity- building and research themselves, rather than relying too much on donor support. Picture on patents The report pointed out that the number of active tech hubs and incubators in Africa had more than doubled since 2016 to 744 as of last year. Almost half of them are located in just five countries, namely, Nigeria (101), South Africa (91), Kenya (70), Egypt (55) and Morocco (41). Even then, outside South Africa which has the most robust patenting record in Africa, the intellectual property regime in the continent has been disappointing, according to the report. “The high cost of registering intellectual property and the lack of a common system is hindering patenting in Africa and the problem is unlikely to be resolved in the near future, since the Pan-African Intellectual Property Organization is taking longer than expected to become operational,” stated the report. As a result, only 17 000 patent applications were registered in Africa in 2018, equivalent to 0.5% of the global total. “Of these patent applications, only 18.4% originated from local residents, according to statistics from the World Intellectual Property Organization’s database,” said Dr Ann Njoki Kingiri, a senior research fellow at the Nairobi-based African Centre for Technology Studies, who was a member of the group that produced UNESCO’s new science report. The report raised hopes for African science, as there were indicators that graduates in science, technology, engineering and mathematics were on the rise across the continent. In most countries, tertiary enrolment in science, technology, engineering and mathematics, or STEM, fields is surpassing 30% in public universities, a factor that may explain the increase in researchers per million inhabitants and volume of research output, according to University World News.
