How will worldwide changes in population affect pressures for international migration in the future? We examine the past three decades, during which population pressures contributed to substantial labor flows from neighboring countries into the United States and Europe, and contrast them with the coming three decades, which will see sharp reductions in labor-supply growth in Latin America but not in Africa or much of the Middle East. Using a gravity-style empirical model, we examine the contribution of changes in relative labor-supply to bilateral migration in the 2000s and then apply this model to project future bilateral flows based on long-run UN forecasts of working-age populations in sending and receiving countries. Because the Americas are entering an era of uniformly low population growth, labor flows across the Rio Grande are projected to slow markedly. Europe, in contrast, will face substantial demographically driven migration pressures from across the Mediterranean for decades to come. Although these projected inflows would triple the first-generation immigrant stocks of larger European countries between 2010 and 2040, they would still absorb only a small fraction of the 800-million-person increase in the working-age population of Sub-Saharan Africa that is projected to occur over this period.

The true origin of the olive is not known but is speculated to be Syria or possibly sub-Saharan Africa. For more than 6000 years, the cultivated olive has developed alongside Mediterranean civilizations and is now commercially produced on more than 23 million acres (9.4 million ha) in the Mediterranean basin. New plantings also exist in California, Chile, Argentina, South Africa, and Australia. Various nonscientific selection processes created a multitude of different cultivars. Many villages in Europe, the Middle East, and North Africa feature distinct varieties. However, it is also common to see the same cultivars with different names and, in some cases, different cultivars with the same name. This is currently being sorted out with DNA identification. The olive tree requires some chilling; tolerates hot, dry conditions; does not like moisture during bloom, and actually produces better with some stress. As a result, olives were traditionally relegated to lands where little else would survive. For thousands of years olives were grown primarily for lamp oil, with little regard for culinary flavor. World production of table olives is now about 1.5 million t/year. The “California Style” black table olive is virtually unknown outside the United States, and this very mild-flavored olive is largely used on pizzas. Elsewhere, table olive recipes are as varied as the villages in the Mediterranean region. Oil styles are also varied, and most olive fruit (≈16 million t/year) is processed into oil. There are about 19 classic styles of olive oil produced in the world, primarily based on specific varieties grown in different regions. In some cases oils are made with a blend of regional varieties. Defective olive oil is common worldwide. The author discusses six of the world's most influential olive oil varieties ‘Picual’, ‘Coratina’, ‘Koroneiki’, ‘Arbequina’, ‘Frantoio’, and ‘Leccino’; covers some horticultural history of oil olive cultivation and processing; and describes the most current trends toward superhigh-density plantings and automated continuous oil processing.

Sub-Saharan African countries are known to be bedeviled with some challenges hindering the economic development. Meanwhile, some of these issues have not been exhaustively investigated in the context of the region. Thus, this study aimed at investigating the implications of government effectiveness, availability of natural resources, and security threats on the regions’ economic development. Yearly data, spanning from 2007 to 2020, was converted from low frequency (yearly) to high frequency (quarterly) and utilized. Data analysis was conducted using Dynamic heterogeneous panel level estimators (PMG and CS-ARDL). Findings show that while PMG estimator confirms a long-run causal effect of governance, natural resources, and security threats on economic development, only natural resources show a short-run causal effect with economic development, while the CS-ARDL (model 2) confirms the significance of all the variables both in the long and short-run. Moreover, the ECT coefficients for both models were found to be statistically significant at less than 1% significance level, which indicates that the systems return back to equilibrium in case of a shock that causes disequilibrium, and in addition, reveals a stable long-run cointegration among the variables in the model. Finally, this study suggests that the policy makers in SSA countries should place more emphasis on improving governance, managing security challenges, and effectively utilizing rents from the natural resources, as all these have severe implications for the economic development of the region if not addressed.

This paper contributes to the understanding of the other neglected effects of trade openness by analysing how it affects life quality in sub-Saharan African countries over the period 2000–2016. We used two trade openness indicators, namely: Squalli and Wilson index and the rate of trade. The empirical evidence is based on a pooled mean group approach. With two panels differentiated by their colonial origin, the following findings are established: the trade openness variable measured by Squalli and Wilson index has no effect on life quality in the both groups of countries in the short-run. However, it has a positive and significant effect on life quality in the both group of countries in the long-run. The use of the rate of trade confirms the results in the both groups of countries in the long-run. The contribution of trade openness to life quality is 3.27 and 5.19 times higher in the Former British Colonies than that recorded in the Former French Colonies of SSA respectively to the use of Squalli and Wilson index and the rate of trade. Overall, we find strong evidence supporting the view that trade openness promotes life quality in SSA countries in the long run.

Drs Terry and Schneider raise legitimate questions regarding changes in polio immunization recommendations. In response to the former, although two doses of inactivated polio vaccine provide humoral immunity that will protect an individual against central nervous system invasion by wild or revertant attenuated polioviruses, they do not provide intestinal immunity, a valued asset of oral polio vaccine (OPV). Because we live in a global community where jet transportation enables one to move from a polio-endemic area to a polio-free area in less than one day, the introduction of wild polio viruses from sub-Saharan Africa or Southeast Asia poses a legitimate threat and concern to those who wish to maintain community protection, in addition to individual protection, against possible reintroduction of wild virus to the United States.

This chapter describes the work of The Balm in Gilead, which grew out of the efforts of Pernessa Seele, an immunologist at Harlem Hospital, to organize local Black faith leaders to address AIDS through the Harlem Week of Prayer for the Healing of AIDS. As Seele trained African American clergy to incorporate AIDS education into their ministry, she also confronted entrenched homophobia in Black religious institutions. Accordingly, The Balm in Gilead designed programs that would help churches accept and include gay members. In 2001, Seele contracted with the Centers for Disease Control and Prevention to extend her work with Black churches to sub-Saharan Africa, setting up programs in Côte d’Ivoire, Kenya, Nigeria, Zimbabwe, and Tanzania. She argued that because of Black people’s particular relationship with church and faith, the approach that The Balm in Gilead had developed in the United States would work in Africa as well. At the same time, this work intersected with a growing interest in addressing “global AIDS” among U.S. leaders, including Presidents Bill Clinton and George W. Bush, who saw the spread of the disease in Africa as a growing threat to international security.
