Neurobehavioral Development in Children With Potential Exposure to Pesticides

Children may be at higher risk than adults from pesticide exposure, due to their rapidly developing physiology, unique behavioral patterns, and interactions with the physical environment. This preliminary study conducted in Ecuador examines the association between household and environmental risk factors for pesticide exposure and neurobehavioral development. We collected data over 6 months in the rural highland region of Cayambe, Ecuador (2003–2004). Children age 24–61 months residing in 3 communities were assessed with the Ages and Stages Questionnaire and the Visual Motor Integration Test. We gathered information on maternal health and work characteristics, the home and community environment, and child characteristics. Growth measurements and a hemoglobin finger-prick blood test were obtained. Multiple linear regression analyses were conducted. Current maternal employment in the flower industry was associated with better developmental scores. Longer hours playing outdoors were associated with lower gross and fine motor and problem solving skills. Children who played with irrigation water scored lower on fine motor skills (8% decrease; 95% confidence interval 9.31 to 0.53), problem-solving skills (7% decrease; 8.40 to 0.39), and Visual Motor Integration test scores (3% decrease; 12.00 to 1.08). These results suggest that certain environmental risk factors for exposure to pesticides may affect child development, with contact with irrigation water of particular concern. However, the relationships between these risk factors and social characteristics are complex, as corporate agriculture may increase risk through pesticide exposure and environmental contamination, while indirectly promoting healthy development by providing health care, relatively higher salaries, and daycare options.

Alternative Development in Ecuador: Prospects for Equitable Growth

Realiza un análisis de la economía ecuatoriana y de sus políticas de desarrollo económico como la sustitución de importaciones e impulso a la industrialización interna y los impactos en la economía de los ajustes estructurales y las reformas neolibarales. Estudia las estrategias de desarrollo en el Ecuador incluyendo la dolarización y expone la precaria situación de vida de la sociedad. Analiza la forma en que se distribuye la riqueza en el país y compara su situación económica con otros países de la región, dando a conocer los coeficientes Gini y los niveles de inequidad. Analiza modelos alternativos de desarrollo más equitativos y sustentables para el país. Finalmente estudia el contexto político del país bajo la presidencia de Rafael Correa, su política económica y social, particularmente el desarrollo de la economía solidaria.

Effect of Community of Residence on Neurobehavioral Development in Infants and Young Children in a Flower-Growing Region of Ecuador

In this study we compared neurobehavioral development in Ecuadoran children living in two communities with high potential for exposure to organophosphate (OP) and carbamate pesticides to that of children living in a community with low potential for exposure. Residence in communities with high potential for exposure to OP and carbamate pesticides was associated with poorer neurobehavioral development of the child even after controlling for major determinants of delayed development. Malnourished populations may be particularly vulnerable to neurobehavioral effects of pesticide exposure.

Extractivism, economic diversification and prospects for sustainable development in Ecuador

The objectives of this paper are first, evaluating economic, social and environmental effects on oil extraction in Ecuador during the last 41 years, and second, discussing prospects to achieving a sustainable and equitable development path in the future, in the context of declining oil reserves. The current government is pursuing an extractivist policy, based on expanding oil extraction in formerly unexploited fields -including those inside the Yasuni National Park- and starting largescale mining exploitation. Two future options will be evaluated, first, an expansion of extractive activities, and second an alternative based on conservation, with sustainable use of natural resources (e.g. ecotourism, agroforestry, bio-knowledge), without expansion of oil field expansion and mining.
