Drought and economic differentiation among Ariaal pastoralists of Kenya

This paper examines the effects of the 1984 drought upon household wealth differences in a community of Ariaal pastoralists of northern Kenya. The database consists of 1985 post-drought livestock counts and informants' statements of species-specific drought loss, compared to 1976 livestock counts on the same 38 households. The analysis confirms the hypothesis that the drought resulted in increased household wealth inequalities. It is suggested that the combination of differential herd growth, differential participation in the cash market, and differential loss to the drought has contributed to a polarization within Ariaal of rich and poor, resulting in rural proletarianization and urban migration.     

Wealth and pastoral dairy production: A case study from Maasailand

Much of pastoral development in Africa has been predicted on the assumed desirability of converting pastoralists to commercial beef producers. Such development has ignored two fundamental aspects of pastoral production: first, the greater human support capacity of a dual milk/meat production system, and second, significant wealth inequality within pastoral communities. This paper presents a case study based on several years of field research in Kenya Maasailand; it examines variations by wealth status in milking strategies and the level of milk offtake for human consumption. Rich households have five times the number of cattle per reference adult as poor households, but similar levels of milk consumption, due to differences in the allocation of milk between calves and people. Residential location and watering frequency also vary by wealth status, contributing to a difference in total milk production per cow.The research and the major part of the writing of this paper were done while the author was a scientist with the Kenya Country Program of the International Livestock Center for Africa. Finishing touches were done at the International Laboratory for Research on Animal Disseases. Neither organization bears responsibility for the content. I wish to thank P. N. deLeeuw for long and valuable discussions; the animal science aspects of the research also benefitted from discussions with K. Wagenaar and M. Nicholson. P. Lembuya was, as always, a faithful and demanding assistant. The useful comments of S. Sandford, T. Conelly, U. Herren, and J. Ensminger are also appreciated.     

Pastoral dairy marketing and household wealth interactions and their implications for calves and humans in Ethiopia

Surveys of pastoral households in a semi-nomadic Borana community during 1987–1988 were used to test the hypothesis that poorer families living closest to a market town would be most affected by the enhanced opportunity to sell dairy products, which would intensify competition between people and calves for milk and have negative implications for calf management. These poorer families indeed reported the highest rates of milk offtake per cow, and the milk increment was probably sold to purchase more grain for human consumption at the expense of milk intake for the calf. Consequently, this strategy may increase the susceptibility of malnourished calves to disease, especially those from lower-producing dams. Benefits of improved human energy intake from grain and retention of livestock capital must be weighed against risks of calf death and possible malnutrition of people from milk restriction when assessing dairy marketing trade-offs that are most acute for the poor. Opportunity to sell dairy products at favorable terms of trade helps the poorest people survive, and their risks could be mitigated by policies that facilitate grain marketing in the rangelands and interventions that improve calf feeding management, diversify human diets, and create alternative opportunities for women to generate income. The households postulated to be most at risk were identified from a complex, but logical, interaction among factors of distance to market, household wealth, and the quality of milking cows held. This indicates that targeting such needy groups for development assistance may require a more detailed and interdisciplinary analysis of production systems than is commonly practiced.     

The impact of past pandemics on economic and gender inequalities

This paper estimates how previous major pandemic events affected economic and gender inequalities in the short- to medium run. We consider the impact of six major pandemic episodes – H3N2 Flu (1968), SARS (2003), H1N1 Swine Flu (2009), MERS (2012), Ebola (2014), and Zika (2016) – on cross-country inequalities in samples of 46–167 countries observed over 1950–2019. Results show that the past pandemics have moderately increased income inequality in the affected countries in the period of four to five years after the pandemic’s start. On the other hand, we do not find any robust negative impacts on wealth inequality. The results concerning gender inequality are less consistent, but we find some evidence of declining gender equality among the hardest hit countries. Moreover, the gender gap in unemployment grew within the four years after the onset of the pandemic.     

The social and economic circumstances of mixed ethnicity children in the UK: findings from the Millennium Cohort Study

The number of people with a ‘mixed’ ethnicity heritage is growing in contemporary Britain. Research in this area has largely focused on implications for cultural and racialized identities, and little is known about associated economic and social factors. Data from the Millennium Cohort Study, a representative panel survey of children born in 2000–2001, are used to examine the circumstances of mixed ethnicity children in comparison with their non-mixed and white counterparts. Findings suggest a cultural location between ‘white’ and minority identities, and socio-economic advantage in comparison with non-mixed counterparts. For example, households of non-mixed white children had poorer economic profiles than households of both mixed white and mixed Indian children. This effect is associated with the presence of a white parent, and the factors underlying it are examined. Although the statistical approach used bypasses a consideration of the dynamics of identity, it provides important evidence on stratification and inequality, and the factors driving this.     

Ethnic culture and social mobility among second-generation Asian Americans

ABSTRACT

This review engages with Jennifer Lee and Min Zhou’s The Asian American Achievement Paradox to consider how ethnic culture matters for social mobility among the immigrant second generation. It describes the strengths and contributions of the book, connects it to broader debates on culture, poverty, and mobility, and draws on my own research on the second generation in New York City. It highlights three additional cultural mechanisms that underlie the Chinese (or Asian) second-generation advantage: social class heterogeneity in the co-ethnic community, intergenerational support in the immigrant family, and the belief in achievements as redemption for parental sacrifice. While pointing out the similarities and differences between Los Angeles and New York, it also suggests possible applications of these cultural mechanisms in explaining second-generation achievements.     

Will income inequality affect environmental quality? Analysis based on China's provincial panel data

During the last two decades of China's rapid economic growth, the gap in citizens’ income has widened and environmental quality has deteriorated. Using Gini coefficients as the measure of income inequality, this study investigated the impacts of income inequality on carbon emissions per capita in China. To control for potential endogeneity and allow for dynamics, the Generalized Method of Moments (GMM) technique is utilized. Moreover, the influential factors that can affect carbon emissions per capita in China have been examined. The empirical results indicate that carbon emissions per capita increase as the income gap expands for nationwide and in the eastern and non-eastern regions of China. Among all factors that may affect carbon emissions per capita, a “U” shaped relationship exists between per capita income and per capita carbon emissions, and increasing the value-added share of secondary industry in the GDP would significantly increase carbon emissions per capita.     

Size-asymmetric root competition in deep,nutrient-poor soil

Aims There is much evidence that plant competition below ground is size symmetric, i.e. that competing plants share contested resources in proportion to their sizes. Several researchers have hypothesized that a patchy distribution of soil nutrients could result in size-asymmetric root competition. We tested this hypothesis.
