This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends establishing in-country facilities for artificial insemination centres and in situ breeding farms.
In Belgium, the pregnancy rate of inter-uterine insemination in humans is around 30 percent after six tries, similar to that of an average, fertile couple conceiving naturally. The cost is around US$200 an attempt.
