Infancia migrante transfronteriza, trabajo infantil y derechos humanos : zona cafetalera, Soconusco, Chiapas.
Provedor de dados: 32
Autores: Ramírez Ramos, Laura Itzel.
El sistema capitalista ha generado dinámicas de desprotección humana que obligan a grandes conglomerados de personas a buscar estrategias que les aseguren mínimos de subsistencia. Este es el caso de las y los jornaleros migrantes guatemaltecos en la frontera sur de México, para quienes la migración y el trabajo infantil, su estrategia, los expone a contextos de alta vulnerabilidad en donde la violación de sus derechos humanos es recurrente. En este marco contextual el objetivo de la presente investigación es aportar datos cuantitativos y cualitativos que describan las características del trabajo infantil, el derecho a la salud y educación de niños y niñas migrantes guatemaltecos en tres fincas cafetaleras en la zona del Soconusco, Chiapas, espacio...

Community forests and protected areas have each been proposed as strategies to stop deforestation. These management strategies should be regarded as hypotheses to be evaluated for their effectiveness in particular places. We evaluated the community-forestry hypothesis and the protected-area hypothesis in community forests with commercial timber production and strict protected areas in the Maya Forest of Guatemala and Mexico. From land-use and land cover change (LUCC) maps derived from satellite images, we compared deforestation in 19 community forests and 11 protected areas in both countries in varying periods from 1988 to 2005. Deforestation rates were higher in protected areas than in community forests, but the differences were not significant. An...

Las tendencias negativas en la abundancia de aves están fuertemente correlacionadas con la disminución de las precipitaciones en un bosque tropical centroamericano
Provedor de dados: 68
Autores: Cerezo Blandón,Alexis; Robbins,Chandler S; Dowell,Barbara; Ramírez,Miguel; López,Antonio; Javier,Obdulio.
El cambio climático es considerado uno de los principales factores que amenazan a la biodiversidad. El clima es de gran importancia para la dinámica poblacional de las aves, pero las consecuencias del cambio climático no han sido abordadas sino hasta recientemente, especialmente en aves tropicales. Para el norte de América Central, los escenarios de cambio climático para 2050 predicen una reducción en las precipitaciones, con disminuciones de 4-19% de las precipitaciones actuales. En este trabajo se evalúa la relación entre los cambios temporales en la cantidad de precipitaciones y la dinámica de la comunidad de aves en el este tropical de Guatemala para un período de 18 años (1993-2010). Los datos consistieron en capturas y recapturas anuales en cuatro...

Insights from the Guatemalan food system: an application of exploratory spatial data analysis techniques for food security analysis
Provedor de dados: 31
Autores: Alcaraz V.,   Gabriela; Zeller,   Manfred.
The achievement of food security for all remains one of the main development objectives worldwide. Most commonly, non-spatial models are developed for either explaining the underlying determinants of food insecurity and undernourishment or for predicting their changes, so as for identifying vulnerable groups for targeting support. Such approach ignores geographic determinants and the spatial dependency of food security and nutrition outcomes. This paper seeks to address this issue. We use nationally representative data from Guatemala, which faces high and rising rates of undernourishment and child stunting in spite of the efforts engaged on their reduction. Through exploratory spatial data analysis and overlay techniques, some elements embedded in the food...

The Impact of an Experimental Nutritional Intervention in Childhood on Education among Guatemalan Adults
Provedor de dados: 31
Autores: Maluccio,   John A.; Hoddinott,   John; Behrman,   Jere R.; Martorell,   Reynaldo; Quisumbing,   Agnes R.; Stein,   Aryeh D.
Early childhood nutrition is thought to have important effects on education, broadly defined to include various forms of learning. We advance beyond previous literature on early childhood nutrition on education in developing countries by (1) using unique longitudinal data from a nutritional experiment with lifetime educational measures; (2) avoiding confounding the estimates by excluding potentially endogenous right-side variables; and (3) using estimators that allow for nonnormal distributions. Our results indicate significantly positive, and fairly substantial, effects of the randomized intervention a quarter century after it ended: increased grade attainment by women, via increased likelihood of entering and completing primary school and some secondary...

Agricultural and Food Security Policy Analysis in Central America: Assessing Local Institutional Capacity, Data Availability, and Outcomes
Provedor de dados: 31
Autores: Tschirley,   David L.; Flores,   Luis; Mather,   David.
Performance of the agricultural sector in developing countries is fundamental to ensuring robust and equitable economic growth and broad-based food security. Yet donor support to agricultural development in developing countries has declined continuously for 30 years. This same period saw dramatic deterioration in developing countries’ institutional capacity to provide services to their agricultural sectors. These trends may now be changing, due in part to the global food price crisis of 2007 and 2008 and concerns that it unleashed about the world’s ability to feed its poorest inhabitants. This paper reports on the results of a two week trip to Guatemala and Nicaragua made by Michigan State University’s Food Security Group. The purpose of the trip was to...

The Guatemala Community Day Care Program: An Example of Effective Urban Programming
Provedor de dados: 31
Autores: Ruel,   Marie T.; Quisumbing,   Agnes R.; Hallman,   Kelly K.; de la Briere,   Benedicte; Coj de Salazar,   Nora.
The community daycare programs currently under way in several Latin American countries seek to promote human capital formation while relieving one of the most pressing constraints faced by working parents, especially mothers—access to reliable and affordable childcare. This research report presents the results of an evaluation of Guatemala’s Community Day Care program, which offers poor families a package of services to promote child nutrition, socialization, and development, under the condition that parents engage in income-generating activities outside the home. The program was created in the early 1990s as a response to the changing needs of the growing urban population. Given Guatemala’s rising rates of urbanization, the growing importance of formal...

Nontraditional Export Crops in Guatemala: Effects on Production, Income, and Nutrition
Provedor de dados: 31
Autores: von Braun,   Joachim; Hotchkiss,   David; Immink,   Maarten.
Modernization of traditional agriculture entalls increased participation of the smallholder sector in the exchange economy. The achievement of this participation requires an open trade regime, domestic policies that ensure against market failures and public policy that effectively permits use of a new production technology for sustained growth. To open up these opportunities to small farmers, investment in rural intrastate is essential, as is investment in education that will enable these farmers to participate as entrepreneurs in the growth process must stimulate employment and increased returns to land. Nontraditional vegetables for export have a higher labor content and therefore promise to help foster rural modernization.  In this study of...

Supermarket Purchases and the Dietary Patterns of  Households in Guatemala
Provedor de dados: 31
Autores: Asfaw,   Abay.
Very limited empirical analyses are done on evaluating how changes in the retail environment affect diet and health status of consumers, especially in developing countries. The major objective of this study is to shed some light on some of these neglected but crucial issues. The study examines the impact of supermarket purchases on dietary practices (defined as the calorie share of different food groups) of Guatemalan households using the 2000 Guatemalan household survey. I use an instrumental variable method to take into account the potential endogeneity of the supermarket-purchase variable in the calorie share equations. The identification strategy relies on two variables: the wife’s occupation (working or housewife) and the overall socioeconomic...

Assessing the Potential for Payments for Watershed Services to Reduce Poverty in Guatemala
Provedor de dados: 31
Autores: Pagiola,   Stefano; Zhang,   Wei; Colom,   Ale.
Payments for Environmental Services (PES) are being increasingly used as conservation instruments, particularly in Latin America. PES programs seek to capture part of the benefits derived from environmental services and channel them to natural resource managers who generate these services, thus increasing their incentive to conserve them. Many have assumed that these payments would go mostly to poor land users, and thus contribute to poverty reduction. There has been little empirical verification of this assumption to date, however.  The PES approach was conceptualized as a mechanism to improve the efficiency of natural resource management, and not as a mechanism for poverty reduction. Pagiola et al. (2005) identified three main questions regarding the...

A study of risk factors associated with the prevalence of Cryptosporidium in villages around Lake Atitlan, Guatemala
Provedor de dados: 55
Autores: Laubach,H. E.; Bentley,C. Z.; Ginter,E. L.; Spalter,J. S.; Jensen,L. A.
Cryptosporidium parvum is an endemic, zoonotic coccidian parasitosis that is highly prevalent in third-world countries where waterborne fecal contamination of food and drink or person-to-person contact with oocysts are the most common methods of transmission of the enteric protozoan. This type of transmission of the parasite made the villages around Lake Atitlan, Guatemala a unique site to compare environmental risk factors with the level of Cryptosporidium infections in the local residents. The study was carried out in two villages, San Antonio Palopo and Santa Catarina Palopo, located in the highlands above the shores of the lake. Smears from stool specimens of patients with gastroenteritis were processed using Kinyoun's modified acid-fast stain and...
