The drivers of sugarcane expansion in Goiás, Brazil
Where Deforestation Leads to Urbanization
Developing the Amazon into a major provider of internationally traded mineral and food commodities has dramatically transformed broad expanses of tropical forests to farm and pasturelands, and to mining sites. The environmental impacts of this transformation, as well as the drivers underlying the process, have already been well documented. In this article we turn our analytical lenses to another, less examined effect of Amazon land use and enviro…
Eco-certification and greening the Brazilian soy and corn supply chains
Garrett et al 's recent letter (2013 Environ. Res. Lett. 8 044055) shows the trade value of Brazil's production of non-genetically modified (GM) crops, and argues that production for this niche market laid the foundation for the expansion of a variety of non-GM and eco-certification systems. We argue that the conditions underlying the development and perpetuation of the non-GM certification systems are transient. The expansion of soy production h…
Recent cropping frequency, expansion, and abandonment in Mato Grosso, Brazil had selective land characteristics
This letter uses satellite remote sensing to examine patterns of cropland expansion, cropland abandonment, and changing cropping frequency in Mato Grosso, Brazil from 2001 to 2011. During this period, Mato Grosso emerged as a globally important center of agricultural production. In 2001, 3.3 million hectares of mechanized agriculture were cultivated in Mato Grosso, of which 500 000 hectares had two commercial crops per growing season (double crop…
Networks Versus Need
Poverty dynamics, ecological endowments, and land use among smallholders in the Brazilian Amazon
Off-farm Work among Rural Households
This article analyzes off-farm work among subsistence-level farmers in theSantarém region of theBrazilianAmazon. We build on the literature on rural livelihoods in theGlobalSouth by exploring how the opportunity to work off the farm is embedded in social relationships. We additionally differentiate our analysis by type of off-farm work, and examine how other characteristics such as human capital, the available labor supply, and access to infrastr…

Collecting Sketch Maps to Understand Property Land Use and Land Cover in Large Surveys
This article describes a method to collect data on the spatial organization of land use within a rural property as part of a large-scale project examining the linkages between household demographic change and land use and land cover change in the Brazilian Amazon. Previous studies used several different spatial approaches, including maps and satellite images, to improve the information collected in standard survey questionnaires. However, few use…

Intergenerational Coresidence Among Small Farmers in Brazilian Amazônia
This article examines intergenerational coresidence among rural farm families near Santarém, Pará, Brazil using survey data collected by the authors on 896 children whose parents live in 175 households on 150 farms. Married adult children, daughters, and the best educated are more likely to live off their parents' rural property (vs. on the property). Results support arguments that coresidence results from the interests of children rather than th…

Population and Upland Crop Production in Nang Rong, Thailand
Land Ownership as a Determinant of International and Internal Migration in Mexico and Internal Migration in Thailand
This study focuses on the effect of land ownership on internal and international out-migration in Mexico and on internal out-migration in Thailand. Land can impact migration in four ways: as wealth; as employment; as an investment opportunity; and through inequality in ownership. Discrete time event history models of individual migration, using data from the Mexican Migration Project (covering Western Mexico) and data from the Nang Rong Project (…
Altruistic and contractual remittances between male and female migrants and households in rural Thailand
Past research has questioned the extent to which remittances are altruistic behaviors versus payments in a contractual relationship between households and migrants. This article explores altruistic and contractual patterns of remittances using a gendered approach. On the basis of results with various levels of significance in regression models, male and female migrants from Nang Rong, Thailand, behave both altruistically and contractually. Howeve…
Land Ownership as a Determinant of Temporary Migration in Nang Rong, Thailand
The Effects of Closely Spaced and Widely Spaced Sibship Size on Intellectual Development
Sibship Size and Intellectual Development
Previous research has consistently found a negative statistical relationship between sibship size and children's intellectual development. Two explanations have been offered for this finding. The prevailing explanation is that the relationship is causal, suggesting that limiting family size would lead to more intelligent children. A second explanation maintains that the relationship is spurious-that one or more undetermined factors correlated wit…
