RIPPLE EFFECT THE PDRT CAMPUS MASTER PLAN

Sizinda, Zimbabwe

OPPORTUNITIES

The Painted Dog Research Trust (PDRT) was establihed to support the endangered African painted dog (Lycaon pictus) and to build local conservation capacity. This studio project invloved the design of PDRT’s campus master plan, with a focus on designing bioremediation systems to treat wastewater within the campus. The site faces threats of frequent droughts and floods that have been exacerbated by climate change. Our design concept draws from traditional Zimba-bwean landscape features and utilizes the ripple to symbolize both the design’s emphasis on water management as well as the PDRT’s mission to spread sustainable land and water practices beyond its campus. This plan also considers the traditional responsibilities of women in Zimbabwean culture and creates opportunities to support their roles.

A MODEL TO SUPPORT LOCAL WOMEN

MEDICINAL PLANT PRODUCTION

Women are healers and collectors of medicinal plants

Women are thatch collec-tors and makers of crafts such as basket weaving

Women are largely responsi-ble for water collection for everyday uses

Women are responsible for fuel wood collection and kitchen gardens

Traditional Ndebele women paint houses for communica-tion and expression
