The goal of this project is to understand why pastoral production is so low in anthropogenic floodplains in sub-Saharan Africa. Pastoral production systems, in which animals are taken to natural forage, are vital in sub-Saharan Africa as they provide most of the animal protein for populations in rural as well as urban areas. However, in recent decades there has been a decrease in high quality grazing areas in natural floodplains due to the construction of dams in Africa’s rivers resulting in reduced livestock production. Although the dams create anthropogenic floodplains, pastoralists have noted that cattle have a lower reproduction rate, lower milk production, and higher calf mortality than in natural floodplains. They explain these effects in terms of lower forage quality and higher parasite loads. These parasites can reduce cattle production and threaten human populations. However, there have been no studies of anthropogenic floodplains to examine these claims. We will use an innovative, transdisciplinary approach that combines ethnographic, ecological, epidemiological, and spatial approaches to evaluate whether the low nutritional value of grasslands and/or the increased presence of parasites are responsible for lower livestock production by comparing cattle and pastures around Lake Maga and in the Logone Floodplain.
The focus of the film is on exploring the differences in the quality of the pastures in the two seasonal grazing areas, e.g., quality and quantity of forage, problems of parasites and other pests, water quality and their relation to animal health and productivity. The film thus shows pastoralists from different groups describing their own practices and their perspective on the differences between herding in the Logone Floodplain and the Lake Maga area.
