Committing to change and gender diversity is easy to say, but getting a company with 155,000 employees across 70 countries to where it needs to be is, to say the least, no small feat.

Hilde Waage, regional HR leader of EMEA & North America for Cargill Aqua Nutrition, has responsibility for a significant portion of the 2,000 employees working across 20 countries and 38 facilities in her division.

Diversity is front and center at Cargill, and the group has made a commitment to the "Paradigm for Parity" initiative, which recognizes the critical importance of having diversity on a staff, finding that companies with 50 percent of women in senior operating roles show a 19 percent higher return on equity than average, for example.
