Towards Sustainable Future
This study examined the adoption of climate-smart agriculture (CSA) technologies and their determinants among smallholder farmers in the Sidaama Region, Ethiopia. A mixed research approach with descriptive and explanatory sequential designs analyzed data from 391 systematically sampled households. A multivariate probit model and logistic regression identified factors influencing adoption. The most adopted CSA technologies were crop diversificatio…
We Have Never Seen These Things in Our Entire Lives
Developing countries are experiencing the effects of climate change and urbanization simultaneously, often without the economic or political capital to address the impacts. Smallholder farmers in these countries are particularly vulnerable, given their limited resources and dependence on rainfed agriculture. On the African continent, Ethiopia is among the countries most impacted by climate change, largely due to drought, in recent years. To exami…
DHEAS and nutritional status among Sidama, Ngandu, and Aka children
OBJECTIVE: Adrenarche, the biological event marked by rising production of dehydroepiandrosterone and its sulfate (DHEAS), may represent a sensitive period in child development, with important implications for adolescence and beyond. Nutritional status, particularly BMI and/or adiposity, has long been hypothesized as a factor in DHEAS production but findings are inconsistent, and few studies have examined this among non-industrialized societies. …

The Sidama Model of Human Development
Demography and stepfamilies among the Chabu of southwestern Ethiopia
The Chabu were mobile hunter-gatherers until they were exposed to extensive farming and a market economy in the 1990s. Like many other hunter-gatherers, they live in small groups or bands in extended families. Extensive sharing of food and childcare (alloparenting) is common in their social lives. Chabu demographic features include lower fertility and higher mortality rates compared to neighbouring farming communities. A high divorce rate charact…
Stepfamilies, adoption and other forms of the family in hunter-gatherers

Effects of Family Demographics and Household Economics on Sidama Children's Nutritional Status
DHEAS patterning across childhood in three sub‐Saharan populations
OBJECTIVES: Hormones have many roles in human ontogeny, including the timing of life history 'switch points' across development. Limited hormonal data exist from non-Western children, leaving a significant gap in our understanding of the diversity of life history patterning. This cross-sectional study examines dehydroepiandrosterone sulfate (DHEAS) production in relation to age, sex, ethnicity, and cortisol concentrations, as well as average age …
The Chabu hunter-gatherers of the highland forests of Southwestern Ethiopia
A paucity of ethnographic data exists on the Chabu hunter-gatherers of Southwestern Ethiopia. Multiple linguistic studies have been conducted because some believe their language is a linguistic isolate, but they are relatively ‘new’ to the ethnographic record. Based on six months’ ethnographic fieldwork and reviews of existing literature, the paper provides an ethnographic introduction of the Chabu ecology, subsistence, settlement, demography, so…
Culture and Psychological Responses to Environmental Shocks
Sidama people occupy a subsistence niche partitioned between traditional enset agropastoralism and transitional maize farming. Enset production is low risk and requires multiple years for cultivation and processing. Maize farming is high risk and high yield, requiring one growing season from planting to harvest. Contrasting enset and maize farming, we examine effects of crop loss and social shocks on Sidama impulsivity. We argue that impulsivity …
Learning to Survive Ecological Risks among the Sidama of Southwestern Ethiopia
Sidama farmers rely on rain-fed agriculture and experience a highly variable natural environment. Recurrent drought, erratic rainfall, and crop and livestock loss are common in mid and lowland areas, but local people are not passive victims of the changing environment: they use accumulated knowledge and skills to respond to and buffer ecological changes. Based on freelists and in-depth interviews with 70 adults and 50 adolescents, this paper desc…
Vulnerability and Resilience of Sidama Enset and Maize Farms in Southwestern Ethiopia
Enset (Ensete ventricosum) is the traditional staple food of Sidama people who live in Rift Valley lowlands to highlands in southwest Ethiopia. Enset is drought resistant, but it matures slowly, requires substantial manure inputs from cattle, and intensive processing. Maize, introduced to Sidamaland in the mid-twentieth century, is common in midlands and lowlands. Maize matures rapidly and provides more kcal/kg than enset, but it is prone to fail…
Sidama Agro-Pastoralism and Ethnobiological Classification of its Primary Plant, Enset (Ensete ventricosum)
Enset is an essential plant for the Ethiopian Sidama system of agropastoralism. Sidama agropastoralism and the folk taxonomy of enset is presented here in ethnographic context. One of several societies of Ethiopia’s enset complex, the highland Sidama are among the most wholly reliant on enset and maintain more enset varieties in their gardens than other groups. Sidama agro-pastoral systems revolve around human-enset-cattle interaction: Sidama eat…
