Pearl millet (Pennisetum glaucum R. Br.) is an important staple and nutritious food crop in the semiarid and arid ecologies of South Asia (SA) and Sub-Saharan Africa (SSA). In view of climate change, depleting water resources, and widespread malnutrition, there is a need to accelerate the rate of genetic gains in pearl millet productivity. This review discusses past strategies and future approaches to accelerate genetic gains to meet future demand. Pearl millet breeding in India has historically evolved very comprehensively from open-pollinated varieties development to hybrid breeding. Availability of stable cytoplasmic male sterility system with adequate restorers and strategic use of genetic resources from India and SSA laid the strong foundation of hybrid breeding. Genetic and cytoplasmic diversification of hybrid parental lines, periodic replacement of hybrids, and breeding disease-resistant and stress-tolerant cultivars have been areas of very high priority. As a result, an annual yield increase of 4% has been realized in the last three decades. There is considerable scope to further accelerate the efforts on hybrid breeding for drought-prone areas in SA and SSA. Heterotic grouping of hybrid parental lines is essential to sustain long-term genetic gains. Time is now ripe for mainstreaming of the nutritional traits improvement in pearl millet breeding programs. New opportunities are emerging to improve the efficiency and precision of breeding. Development and application of high-throughput genomic tools, speed breeding, and precision phenotyping protocols need to be intensified to exploit a huge wealth of native genetic variation available in pearl millet to accelerate the genetic gains.

The production of pearl millet (Pennisetum glaucum (L.) R.Br.) is important in Namibia, in sub-Saharan Africa, owing to the prevailing low precipitation conditions. Most fields supporting crop production in northern Namibia are located in a network of seasonal wetlands. The aim of the present study was to evaluate the effects of ridging and fertilizer application on the yield and the growth of pearl millet in the seasonal wetlands under different rainfall conditions. The study was conducted for two years (2017–2018) in the experimental fields in northern Namibia, and yield, yield components, and growth parameters were evaluated in relation to the application of different fertilizers (manure and mineral) with and without ridge-furrows. Manure fertilizer application presented the highest yield in 2018, whereas mineral fertilizer application showed the highest yield in 2017. The proportion of rainfall was the highest during the mid-growth period in 2017, and the reproductive stage in 2018. Thus, pearl millet plants under manure fertilization overcame damage resulting from waterlogging stress during the seed setting stage by improving the soil and plant nutrient conditions. In contrast, the plants under mineral fertilization were more tolerant to large amounts of rain during the mid-growth period. In this study, yield was mainly determined by total dry weight, and it was closely related to panicle density in both years. Therefore, we concluded that fertilizer application, including additional fertilizer based on the growth diagnostic, could be important for improving crop production in seasonal wetlands.

Abstract The parasitic plant purple witchweed [Striga hermonthica (Del.) Benth.] poses a serious threat to cereal production in sub-Saharan Africa. Under natural infestation, the wild pearl millet [Pennisetum glaucum (L.) R. Br.] line 29Aw demonstrates resistance against the parasite, but the mechanism of its resistance is unknown. Striga resistance can be due to: (i) low induction of Striga germination (pre-attachment resistance) or (ii) inhibition of parasite attachment and development (post-attachment resistance). Germination bioassays and root chamber (rhizotron) resistance screening assays were used to determine the extent of pre- and post-attachment Striga resistance in 29Aw compared with the Striga-susceptible SOSAT-C88-P10 variety. Regarding pre-attachment resistance, 29Aw stimulated 10-fold less Striga seed germination at a maximum germination distance of 7.96 ± 2.75 mm from the host root compared with 35.94 ± 2.88 mm in SOSAT-C88-P10. Post-attachment resistance revealed 10 to 19-fold fewer, 2.5-fold shorter, and 28-fold less Striga seedling biomass growing on 29Aw compared to SOSAT-C88-P10. Microscopic analysis showed that Striga penetration in 29Aw was blocked at endodermis and cortex levels. Post-attachment resistance in 29Aw was further supported by fewer (22%) Striga-host vascular connections in 29Aw compared to 79% in SOSAT-C88-P10. Together, these findings demonstrate that 29Aw harbors both pre- and post-attachment resistance mechanisms against S. hermonthica.

Pearl millet [Pennisetum glaucum (L.) R. Br.] is an underutilized small grain, nutrient-rich cereal crop cultivated in the arid and semi-arid tropics of Asia and Africa. However, several barriers exist that preclude the full exploitation of the crop such as low yield, inadequate processing technologies, lack of extension support and limited productive varieties. Furthermore, anti-nutritional factors in the grain such as polyphenols reduce digestibility, palatability and bio-availability of other nutrients. Reduction or elimination of these anti-nutritional factors through pre-treatments like boiling, cooking, roasting, soaking improves the nutritional quality of the grain. Underutilized pearl millet genetic resources and processing has the potential to contribute towards sustainable agriculture particularly in drought prone and marginal areas of Africa. This review focuses on nutritional value, pearl millet cultivation and utilization challenges, processing and value addition interventions to improve crop adoption and productivity in sub-Saharan Africa.

The 1918–19 influenza pandemic killed between 30 and 50 million people worldwide. In Sub-Saharan Africa, as Terence Ranger points out, the pandemic left an indelible mark, including the unforeseen emergence of anti-medical religious movements. None were as significant as Faith Tabernacle Congregation, the Philadelphia-based divine-healing church that spurred a massive revival in West Africa – and a network stretching from Ivory Coast to Nigeria – without ever sending missionaries. They evangelised through personal letters exchanged across the Atlantic, and Faith Tabernacle literature sent from Philadelphia to various leaders in West Africa. The 1918–19 influenza pandemic was the spark that led to the church's massive growth, from one small branch before the pandemic began in 1918 to 10,500 members and nearly 250 branches of Faith Tabernacle in West Africa at its zenith in 1926. After the church's rapid demise between 1926 and 1929, leaders of Faith Tabernacle established most of the oldest Pentecostal Churches in the Gold Coast and Nigeria – such as the Apostolic Faith, the Apostolic Church, the Christ Apostolic Church and the Assemblies of God (Nigeria). Classical Pentecostalism, therefore, is Faith Tabernacle's legacy in West Africa, while abstinence from orthodox medicine continued to be debated within these Pentecostal circles.

Abstract Background The use of modern contraception has increased in much of sub-Saharan Africa (SSA). However, the extent to which changes have occurred across the wealth spectrum among adolescents is not well known. We examine poor-rich gaps in demand for family planning satisfied by modern methods (DFPSm) among sexually active adolescent girls and young women (AGYW) using data from national household surveys. Methods We used recent Demographic and Health Surveys and Multiple Indicator Cluster Surveys to describe levels of wealth-related inequalities in DFPSm among sexually active AGYW using an asset index as an indicator of wealth. Further, we used data from countries with more than one survey conducted from 2000 to assess DFPSm trends. We fitted linear models to estimate annual average rate of change (AARC) by country. We fitted random effects regression models to estimate regional AARC in DFPSm. All analysis were stratified by marital status. Results Overall, there was significant wealth-related disparities in DFPSm in West Africa only (17.8 percentage points (pp)) among married AGYW. The disparities were significant in 5 out of 10 countries in Eastern, 2 out of 6 in Central, and 7 out of 12 in West among married AGYW and in 2 out of 6 in Central and 2 out of 9 in West Africa among unmarried AGYW. Overall, DFPSm among married AGYW increased over time in both poorest (AARC = 1.6%, p < 0.001) and richest (AARC = 1.4%, p < 0.001) households and among unmarried AGYW from poorest households (AARC = 0.8%, p = 0.045). DPFSm increased over time among married and unmarried AGYW from poorest households in Eastern (AARC = 2.4%, p < 0.001) and Southern sub-regions (AARC = 2.1%, p = 0.030) respectively. Rwanda and Liberia had the largest increases in DPFSm among married AGYW from poorest (AARC = 5.2%, p < 0.001) and richest (AARC = 5.3%, p < 0.001) households respectively. There were decreasing DFPSm trends among both married (AARC = − 1.7%, p < 0.001) and unmarried (AARC = − 4.7%, p < 0.001) AGYW from poorest households in Mozambique. Conclusion Despite rapid improvements in DFPSm among married AGYW from the poorest households in many SSA countries there have been only modest reductions in wealth-related inequalities. Significant inequalities remain, especially among married AGYW. DFPSm stalled in most sub-regions among unmarried AGYW.

Economic Imperialism

Abstract The West African political economy has been shaped by the policies, decisions and actions of dominant European imperialist countries since about over 500 years. Starting with imperial merchant capitalism along the West African coast in the 16th Century and French gradual acquisition of Senegal as a colony as from 1677, West Africa has remained under the imperialist hold. West Africa remains economically dependent on its former colonial masters despite more than 60 years since the countries started gaining independence. The consequences of economic imperialism on West Africa have included exploitative resource extraction, proxy and resource influenced civil wars, illegal trade in natural resources, mass poverty, and external migration of skilled workers necessary for national development. The world sees and broadcasts poverty, starvation, conflict and Saharan migration in the West African sub-continent, but hardly reports the exploitative imperialistic processes that have produced poverty and misery in West Africa in particular and across sub-Saharan Africa in general.
