Women account for only one third of the world's researchers and hold fewer senior positions compared to men at top universities, according to the United Nations Secretary-General Antonio Guterres.

The U.N. chief made the remarks as the world marked the International Day of Women and Girls in Science, on Thursday.

The day was set aside to push the world to achieve full and equal access to and participation in science for women and girls.

"Advancing gender equality in science and technology is essential for building a better future", said Guterres.

"We have seen this yet again in the fight against COVID-19".

Guterres noted that women in the science field faced greater challenges in their duties, especially during the COVID-19 pandemic. These challenges include closed laboratories and increased care responsibilities.

He bemoaned stereotypes that have locked many girls out of science, instead opting to pursue other fields that are seen to accommodate women more.

"Women and girls belong in science", stressed the Secretary-General.

The U.N. chief underscored the need to recognize that "greater diversity fosters greater innovation".

"Without more women in STEM [science, technology, engineering and mathematics], the world will continue to be designed by and for men, and the potential of girls and women will remain untapped", he said.

Guterres also noted that women’s presence is critical in achieving the Sustainable Development Goals (SDGs), to close gender pay gaps and boost women’s earnings by $299 billion over the next ten years.

"STEM skills are also crucial in closing the global Internet user gap", he said, urging everyone to "end gender discrimination, and ensure that all women and girls fulfill their potential and are an integral part in building a better world for all".
