Female pastoralists exhibit great strength in the drive to make a dependable livelihood from livestock tending. This is not without challenges that are genderspecific. This paper examines the socio-economic and environmental challenges faced by women pastoralists in the Sahelian Region of Northern Nigeria. Primary data were derived from an interview of 2,290 adult female household members in 6 local government areas in Bauchi and Gombe States in Nigeria. A stepwise regression analysis determined that amongst 23 socio-economic variables, 14 were significant explanatory or predictive variables (p < 0.05) for the socioeconomic status of women, as a measure of their capacity to sustain pastoralism. The results indicate that the length of time or experience in pastoralism had the most predictive power (β = 0.31; p < 0.05), and contributed 13% (R2 = 0.13) in enhancing the socio-economic status of pastoralist women. This was followed by other socio-economic factors such as the level of formal educational attained, participation in household livestock raising, ownership of large livestock, climate change awareness, prevalence of out-of-school children within the household, availability of household transportation means, category of health care facility accessed, involvement in non-agricultural economic sectors, involvement in food crop farming, ownership of small livestock, amount of rest/sleep affordable, membership of community development groups, and age. The paper recommends support for female education in pastoral communities, access to health care in remote areas, and upgrading community development groups to cooperative or self-help groups that can provide affordable loans to assist pastoralist women in thriving better in a supposedly male-dominated profession.

Climate change, environmental degradation, and descent-based slavery are prevailing issues in Mauritania. The relationship between the three phenomena has rarely elicited investigation, in part due to the perception that chattel slavery is an institution of the past. Despite being the last country in the world to decree its abolition in 1981, Mauritania is alleged to have one of the highest incidences of slavery in the world today. This study explores the nexus between climate change and slavery in Mauritania. The paper seeks to elucidate how the environmental interactions of the Sahel have transformed slavery’s manifestation in this multiethnic northwest African republic for more than a millennium. The author contributes to the rich literature on slavery in Mauritania by arguing that in the twenty-first century, the nexus converges on the issue of development, and that the prevalence of slavery degrades the country’s precarious environment and contributes to its underdevelopment.

The research aims to explore the complex and interrelated connections of climate change, conflict and migration in the Sahel region. Furthermore, it explores the patterns of human mobility, both internal displacement and cross-border migration, driven by climate-related environmental stressors, food insecurity, and conflict-induced displacement. The Sahel region of Africa stands at the crossroads of intersecting environmental stressors and human mobility, with climate change acting as a catalyst for conflict and migration. Using an interdisciplinary approach, this research synthesizes existing literature and incorporates quantitative analysis, qualitative insights, and geospatial mapping. It highlights case studies to explore the complex relationships between climate change, conflict, and migration in the Sahel. The study identified notable patterns in which environmental stressors, such as droughts, are closely associated with a rise in violence and displacement. The results explain how these stressors increase rivalry for limited resources, therefore intensifying disputes and stimulating migration. To address the challenges the region is facing, implement sustainable resource management and diversified economic opportunities, alongside robust governance to manage conflicts and promote social unity. Enhance community resilience through infrastructure investment and advance research, analytical tools, and multi-level stakeholder engagement for comprehensive problem-solving.

The mid-Pliocene (approximately 3.3–3.0 Ma) was one of the past geological warm periods. Since this past warmer climate was in many respects comparable to near future warming projections, how the regional monsoonal rainfall changed during the mid-Pliocene is an important scientific and socioeconomic concern. Based on phase 2 of the Pliocene Model Intercomparison Project (PlioMIP2), this work examines the simulated changes of Sahel summer rainfall during the mid-Pliocene. The results show the considerable intermodel uncertainty of the simulated mid-Pliocene Sahel rainfall changes in the PlioMIP2 multimodel ensemble, which is due to the uncertainties of both the simulated dynamic and thermodynamic responses to this past warmer climate. In particular, we find that the intermodel spread in the simulated northern North American warming is a major source of the uncertainty of the mid-Pliocene Sahel summer rainfall changes through two processes. One is a direct dynamic process: a stronger warming over northern North America could enhance the meridional temperature gradient between the extratropical and tropical regions, inducing an interhemisphere energy imbalance of the atmosphere. This could lead to a northward shift of the intertropical convergence zone, strengthening the Western African summer monsoon (WASM) circulation and Sahel summer rainfall. Another is an indirect thermodynamic process: the strengthened WASM circulation could further induce anomalous moisture convergence over the Sahel region, increasing local atmospheric moisture at the low-level troposphere, in favor of a wetter Sahel. Our results suggest that an improved warming simulation over northern North America is essential for the hydrological cycle simulation around the Sahel in the mid-Pliocene warmer climate. Significance Statement: The Sahel summer rainfall change in a global warmer climate is a widespread scientific and socioeconomic issue because of its important impacts on regional agriculture, ecosystems, food security, water resources, and even cultural environment. However, the present study identifies a nonnegligible intermodel uncertainty of the simulated Sahel rainfall changes during the mid-Pliocene (one of the most recent geological warm periods in Earth's history) in the Pliocene Model Intercomparison Project phase 2 (PlioMIP2) multimodel ensemble. In particular, such an intermodel uncertainty of the simulated Sahel rainfall changes during the mid-Pliocene is attributed to that of the simulated northern North America warming via both the direct dynamic process and the indirect thermodynamic process. This is quite different from the uncertainty source of near-future projections of Sahel summer rainfall changes. The present results improve our understanding of the underlying physics of the hydrological cycle change around the Sahel region in the mid-Pliocene warmer climate, with implications for the future projections of regional monsoonal rainfall.
