“…Migration is most often associated with the movement of young adults, typically males between the ages of 20 and 35, who migrate for employment 14,19,30,31 . We found that migration of leprosy-affected individuals was significantly associated with being male after diagnosis, and overall, migrants were slightly older than the younger age-set typical of migration globally.…”

“…VanWey (2003) showed that households in Nang Rong, Thailand pursued temporary migration as a form of income diversification, with the size of land holdings affecting the probability of migration differentially for male and female migrants. Barbieri et al (2009) additionally found that community-level context, including access to road networks, health centers, and schools affects the balance of rural-rural and rural-urban migration. Although road networks were found to increase rural-urban migration, increased road access is also associated with increased off-farm employment opportunities in rural areas.…”

The effect of reciprocal connections between demographic decision making and land use on decadal dynamics of population and land-use change. Ecology and Society 19(2): 31. http://dx.doi.org/10.5751/ ES-06243-190231 Research, part of a Special Feature on Exploring Feedbacks in Coupled Human and Natural Systems (CHANS) ABSTRACT. Although much focus has been given to the study of land use and land cover (LULC) and population change, studies have tended to focus on relationships in a single direction, for instance, the consequences of changing LULC for population processes, or the consequences of changing population dynamics for LULC. Given the highly coupled nature of human-environment systems, we cannot fully understand these systems without considering reciprocal causality, or "feedbacks." This analysis focuses on the Chitwan District of south-central Nepal, a high priority conservation area, and seeks to address the question of how feedbacks between land use and microlevel human decision making impact the decadal time scale dynamics of population and land-use change. It investigates two feedback loops connecting land use and demographic decision making: agricultural land use -marriage timing; and agricultural land use -fertility. Marriage is closely tied to land use in Chitwan because new households in Chitwan are established primarily after marriage. Fertility is connected to land use because of its linkage with population size and future new household formation. However, prior research in Chitwan has shown that residents of agricultural neighborhoods tend to marry earlier, and to have children sooner after marriage. Using an agent-based model, we compare model outcomes from scenarios with and without these feedback loops. Our results indicate that these feedbacks lead to statistically significant differences in population and in land-use outcomes. However, the sizes of these differences are relatively small in magnitude (less than 8% for the scenarios considered here), even over a 50-year time scale. These findings are a reminder that CHANS researchers must be careful to consider both effect size and significance when considering the policy implications of model outcomes.

“…A unidade doméstica não depende exclusivamente da disponibilidade de mão de obra familiar, havendo um arranjo complexo que envolve troca de serviço (compadrio), venda própria da mão de obra e contratação, forte relação familiar, interface rural-urbana e uso da terra em propriedade distinta. A fecundidade deixa de ser importante como variável explicativa, estimulando uma nova frente investigativa que considera os elementos da contemporânea realidade dos ambientes pós-fronteira (BARBIERI; CARR; BILSBORROW, 2009;VANWEY;LUDEWIGS, 2011;GUEDES et al, 2011;VANWEY;VANWEY et al, 2006).…”

Pensando de forma integrada a relação população-ambiente, o artigo aborda os estudos sobre dinâmica populacional e mudança no uso e cobertura da terra, com foco na contribuição e nos desafios da Demografia. Aproximando-se do tema em meados dos anos 1990, a Demografia teve como principal contribuição destacar a importância dos componentes populacionais nos modelos, antes, colocados como secundários e sob uma perspectiva simples. Demógrafos brasileiros dedicados a questões ambientais, embora tivessem prioritariamente a temática urbana no seu escopo, colaboraram de maneira indireta para a desenvoltura do campo, ao proporem uma releitura sobre relações população-ambiente. O artigo parte do caso da Amazônia brasileira, mostrando como a população foi explorada nas teorias sobre mudanças nos usos e coberturas da terra, passando pelo viés do crescimento populacional durante o período de fronteira agrícola, o modelo de ciclo de vida do domicílio (fecundidade e composição do domicílio) na década de 1990 e, mais recentemente, o enfoque no componente migratório. Para a Demografia, aponta-se como essencial o aprofundamento nos elementos demográficos que não o volume e a inclusão do espaço e seus efeitos. Para a construção da Ciência da Mudança da Terra, destacam-se a incorporação de dinâmicas urbanas nas investigações, a adoção de uma metodologia multiescalar e o exercício do diálogo entre as diversas disciplinas, incorporando mais sistematicamente a contribuição da Demografia.Palavras-chaves: Demografia. Mudança no uso e cobertura da terra, Amazônia.
