Les latrines a fosse et ventilee et ameliorees au Zimbabwe : d'une innovation locale a une solution globale d'assainissement
Pande, Rohini P. | Yazbeck, Abdo S.
This Field Note describes the development of the ventilated improved pit (VIP) latrine in Zimbabwe. This innovative latrine was invented at the Ministry of Health's Blair Research Laboratory in 1973, and subsequently adopted as the standard sanitation technology promoted by the Ministry of Health. For some years it was implemented at a large scale by the government's national rural water and sanitation program, until the decline of the national economy. Despite that decline, however, the VIP latrine itself is still popular and is currently being promoted in various forms by local NGOs and others. The VIP latrine is known and used in countries all over the world. Within Zimbabwe itself, the VIP latrine is known as the Blair latrine and is a national institution. It is still the sanitation technology of choice for most rural households. Its success demonstrates that well-supported local research can produce innovative technologies that are ideally suited to local conditions, and that home-grown technologies can generate significant political and popular support. Its inclusion in the school curriculum has meant that an entire generation of Zimbabweans has grown up with an appreciation of the benefits of the VIP latrine. In addition, the involvement of so many government staff in the national sanitation program, and the training that this program provided to thousands of VIP latrine builders, have further enhanced its reputation and support.
