The Depopulation of Upper Amazonia in Colonial Times

In Upper Amazonia, after an initial disastrous penetration of Spanish colonists, the Jesuits began the task of evangelization in 1638. A network of Missions covered the territory and some statistics were collected. The indigenous demographic system was characterized by high mobility and high fragmentation of the various communities, as well as rapid turnover of the missions' population. The Iberian intrusion increased the fragmentation, and many nations migrated away from the riverine areas (várzea) into the rainforest, with less favorable living conditions. This process may have pushed a number of communities under the threshold of minimum size for viability, thus accelerating the demographic collapse.En el Alto Amazonas, después de la desastrosa penetración inicial de los colonos españoles, los jesuitas empezaron la tarea de evangelización en 1638. Una red de misiones cubrió todo el territorio y se recogieron estadísticas. El sistema demográfico indígena se caracterizó por su alta movilidad y la gran fragmentación de algunas comunidades, además de por la rápida rotación de la población de las misiones. La intrusión ibérica aumentó esta fragmentación y muchas naciones migraron fuera de las zonas ribereñas (várzea) hacia la selva, donde las condiciones de vida eran menos favorables. Puede que este proceso empujara a muchas comunidades por debajo del umbral mínimo de la viabilidad y acelerase el colapso demográfico

Las múltiples causas de la catástrofe: consideraciones teóricas y empíricas

The aim of this article is to contribute to the analysis of the indigenous population decline, namely the weight, role and function of every one of the causes that originated it. It is argued that the attention given to epidemies and pathologies has entailed a simplification that may seriously distort the historical interpretation of the demographic catastrophe, and that other contributing factors must be analyzed. Special attention is given to two of these factors which weigh on reproductivity and, therefore, on the capacity of reaction to crisis and mortality, namely the «displacement effect» and the «substraction effect» –social displacement and taking away of the reproductive heritage.El objetivo de este estudio es contribuir a la difícil labor de analizar el peso, el papel y la función de cada una de las causas que originaron el declive demográfico de los pueblos indígenas. La importancia que se ha dado a las epidemias y patologías en el descenso de la población ha llevado a una simplificación que puede distorsionar gravemente la interpretación histórica de la catástrofe demográfica. Junto a las epidemias, deben analizarse otros factores que contribuyeron al descenso de dicha población. Dos de ellos merecen una especial atención, ya que afectan a la reproductividad y por consiguiente, a la capacidad de reacción frente a las crisis y a los episodios de mayor mortalidad; nos referimos al «efecto de desplazamiento» y al «efecto de sustracción», desplazamiento social y sustracción del patrimonio reproductivo

The Decline of Remarriage: Evidence From German Village Populations in the Eighteenth and Nineteenth Centuries

Family reconstitution data for fourteen German village populations permit the examination of remarriage during the eighteenth and nineteenth cen turies. The results provide compelling evidence for a secular decline in the tenden cy to remarry. Pronounced age and sex differentials in the likelihood of remar riage were evident: widows were far less likely to remarry than widowers, and the probability of remarriage declined rapidly with age, particularly for women. The probability of remarriage was also inversely associated with the number and age of children. There were, however, no clear differences in either the probability of remarriage or its tendency to decline over time among major occupational groups. The decline in remarriage probabilities was caused in part by declines in adult mortality, which gradually raised the ages of surviving spouses to levels at which remarriage has historically been rather unlikely. However, age-specific marriage probabilities also declined, affecting both men and women and all oc cupational groups, suggesting the presence of a social change of wide scope. Some comments on possible factors contributing to the decline of remarriage are presented. The need for a comprehensive explanation of remarriage trends and differentials remains an important challenge for family historians.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68212/2/10.1177_036319908501000103.pd

HIV/AIDS, demography and development: individual choices versus public policies in SSA

Despite the increasing rate of diffusion of effective therapies, the battle against HIV/AIDS in Sub-Saharan Africa (SSA) is far from being over. Three main challenges are that the epidemics might paralyse or reverse the fertility transition, the expansion of the resources needed to finance the fight against HIV, and the emerging resistance to anti-retroviral treatments. This research proposes a UGT-like model showing the complexity of the interplay amongst the (macro)economy, the epidemics, their endogenous feedback on mortality and fertility and the central role of policy actions aimed to fight HIV. The disease-induced increase in adult mortality can hamper economic development by its upward pressure on the precautionary demand for children and downward pressure on education. This can dramatically reduce physical and human capital accumulation
