Rural trans­portation to alleviate transportation burdens of rural women was one of his favorite projects. The research study confirmed that women, assisted by their daughters, were responsible for water and firewood collection; and spent from 1 hour to over 4 hours, tra­ve­ling 2 to 7 km while carrying a load of 20 kg, every day. Their do­mes­tic demands accounted for 45-60 percent of the time and 80-90 percent of human energy, dedicated to their daily transport needs. Because the heavy loads were carried on their heads, this time-con­sum­ing, daily activity had serious health problems for the women.

It became clear from the analysis that rural domestic transport needs should seriously focus on women’s efforts, and improved transportation could potentially free up considerable resources for more productive and welfare-enhancing activities, and/or allow for increased utilization of a facility that would be conducive to household welfare and health of the women. Strong evidence from the study emerged that if such projects are to have an impact, their design must be based on an understanding of local situation of women; must incorporate the expertise, knowledge and perceptions of women on water and firewood collection, cooking and other crop processing tasks; and must involve women in their implementation.

In 1971 Kristian returned to Denmark to establish a design studio in Thyholm, in North-Western Jutland, to continue with his work and try to establish residential joint projects and cooperation between Kenya and Denmark.
