Kesa Kishida, with 20 years' experience in Kenya, is a JICA expert. She travels to two model regions in Kenya from her base in Nairobi, and gives instruction to villagers on many topics, including preventing AIDS, family planning, and promoting hygiene.

Kishida's duties include the promotion of family planing to reduce population growth, including the use of videotapes at meetings, as well as promoting a sense of hygiene for pregnant women, 90% of whom currently give birth at home. Other activities include instructing local women on how to use locally-grown wheat to make their own bread, thereby improving their diets and enabling them to earn cash income.

In addition to these activities, Kishida also promotes the use of an improved oven, the "Enzalo Oven." This oven was designed from ovens used in Iwate Prefecture, Kishida's birthplace. The Enzalo Oven is quietly penetrating and taking hold in rural areas of Kenya. In contrast to the traditional cooking fire in Kenya, which involves a pot placed on top of three stones, the Enzalo Oven is made using sun-dried bricks. Cooking is possible over three heat vents at once, and the oven offers a high cooking efficiency. By using the oven, less firewood will be necessary, which should also be of major assistance in reducing deforestation. Moreover, the remaining heat after cooking is used to sterilize water through boiling. By drinking water sterilized in this manner, villagers report a lower incidence of dysentery among infants.

At the health center in Kiberechia, Kenya, Kishida and JICA member Hosokawa use materials developed by the project to promote education on population control among local residents.

This improved oven (Enzalo Oven) is becoming widely used throughout Kenya.
