Ethnic heterogeneity of knowledge on termites and human consumption in southern Cameroon

Termites are both pests and non-conventional food resources in Sub-Saharan Africa. Many are reluctant to eat them, and the reasons for this rejection are poorly known. This study examined level of knowledge, and acceptance by members of the 10 main ethnic groups of southern Cameroon. Most respondents (86 percent) were aware of termites as food with sixteen vernacular names in the study areas. Acceptance among ethnic groups for consumption varied between 96 percent and 8 percent of people in a group. Barriers included being raised to not eat termites, not having many opportunities to eat termites, and dislike of the taste.

Participatory Mapping with High-resolution Satellite Imagery: A Mixed Method Assessment of Land Degradation and Rehabilitation in Northern Burkina Faso

Sahelian West Africa is a region that has high population densities and that has frequent severe droughts and enormous pressure on natural resources. Because of these challenges, it is the place where the term desertification was originally coined. Recently, however, experts have identified large zones of greening where the amount of vegetation exceeds what one would expect based on rainfall alone. This pattern is well documented, but its mechanisms remain poorly understood. This research employs participatory mapping linked with high-resolution satellite imagery to better understand the human role behind regional vegetation trends. Through a case study of three communities in northern Burkina Faso, this paper presents a pilot methodology for explicitly mapping perceived areas of both land degradation and rehabilitation. Combining participatory mapping exercises with standard image classification techniques allows areas of land degradation and rehabilitation to be precisely located and their extents measured for individual communities and their surrounding terroirs. Results of the spatial analysis show that the relative proportion of greening and browning varies among communities. In the case of Sakou, nearly 60 percent of its terroir is degraded. While in another, Kouka, this is 48 percent. This method also elicits perspectives of Burkinabè agro-pastoralists on the local land-use practices driving these twin environmental processes. Altogether, this case study demonstrates the analytical power of integrating ethnography and high-resolution satellite imagery to provide a bottom-up perspective on social-ecological dynamics.

Transmission and Erosion of Local Knowledge Practices in a Fishing Village in South India

Fishermen acquire knowledge through kin or other members of the community in an informal way, as well as through personal experience. The knowledge thus acquired is viewed as an asset, but the dangers of its erosion are well understood by the fisher communities. This study documents local knowledge based on the experience, observation, and experimentation of the Jalari fishing community in South India. We focus on wave/ocean colors, sea currents, reading the weather, and availability of fishes in different seasons. Cultural transmission and factors potentially influencing the sustenance and erosion of knowledge practices are briefly considered.
