RESUMO

This paper presents details from the field test of two rapid surveys in Ecuador in 1995. It focuses on how the surveys were designed and implemented, including descriptions of the sampling procedures, the preparation and use of preprogrammed palmtop computers for data entry, the selection criteria for the interviewing team, and how the training was designed. Lessons are drawn that will assist health professionals plan and carry out better rapid data collection in the future. The objective of the study was to evaluate the reliability and validity of data gathered during the rapid surveys as compared with a recent "gold standard" national survey. A two-way factorial design was used to control for differences in sampling (probability versus quasi-probability) and methods of data collection (paper versus palmtop computer). Few differences were detected between the surveys done on palmtops as compared to paper ones, but urban and rural differentials in contraceptive use were less pronounced in the rapid surveys than in the earlier, national survey. This suggests that caution should be exercised in interpreting the disaggregated data in these rapid surveys. In-depth interviews revealed two features of the rapid surveys that were especially popular: the palmtops for their speed of data entry, and the short questionnaire for its "low impact" on a respondent's time. The common belief that computers would disturb respondents was not found to be the case. Even with no computer experience, the interviewers rapidly mastered the new technology.

RESUMO

The authors use survey data collected in 1990 from 418 household heads of recent settlements in the Ecuadorian Amazon to study the extent of and reasons for out-migration of the settlers' children. "Our research identifies the types and incidence of out-migration of young adults from settler households in the Ecuadorian Amazon, as well as the effects of individual and household-level factors of out-migration. Important gender differences in both the levels and patterns of migration and in the factors affecting migration decisions are documented."

RESUMO

PIP: Available arable land in Latin America is actually less than figures indicate, and it is being degraded at a rapid pace. Six Latin American countries are unable to meet their demand for fuelwood, and 10 more are depleting their forests at annual rates of up to 3.8% per year. Land extensification is a national policy in several countries as an alternative to land reform, or subdivision of large land holdings. Guatemala is a case in point. 48% of Guatemala's land is classified as arable, and 80% of this land was already enclosed as farms in the last agricultural census, in 1979. 60% of this land was actually being farmed. 60% of all farms encompass 3.7% of all the farm land, small holdings called minifundia. Between 1964 and 1979 farm numbers increased 45%, total area being farmed rose 13.5%, with an annual increase of 1.2%. Most new farms were settled in the northwestern highlands called the altiplano, where numbers of farms doubled and average size of smallholdings shrank from 0.7-0.45 ha between 1964-1979. The northern lowland tropical forest region, the Peten, is being cut for farmland at one of the fastest rates in the world. Flooding and erosion, as well as urbanization, are also causing irreplaceable loss of farmland. While environmental decline is being recognized in many Latin American countries, the causative role of population growth has not been mentioned in environmental declarations and action plans.^ieng

RESUMO

"This paper examines characteristics of recent rural-urban out-migrants leaving households in the Sierra of Ecuador. A large, household survey focussing specifically on migration is utilized, allowing detailed crosstabulations by sex and origin-destination combination and providing information about migrants generally not found in more generic surveys or censuses. Differences are noted between migrants and non-migrants in basic demographic characteristics, reasons for migrating, and economic activities prior to and subsequent to moving. Differences in the characteristics of migrants moving between various types of place of origin and place of destination are also noted." (SUMMARY IN ENG)

RESUMO

It is widely believed that structural variables such as inequitable land distribution, lack of rural employment opportunities, and rural-urban wage and amenity gaps influence population movements in developing countries. Yet quantitative evidence is scant. In this paper a multilevel model is used to investigate the effects of individual-, household-, and areal-level factors on rural-urban out-migration in the Ecuadorian Sierra. Data from a detailed survey carried out in 1977-1978 and from government macro-areal statistics are used to investigate factors affecting the out-migration of youths aged 12-25. Preliminary conclusions are presented on the usefulness of multilevel models in studying migration and policy implications for Ecuador.

RESUMO

Breast-feeding is important to infant nutrition, morbidity, and mortality, and to postpartum amenorrhea (hence to birth intervals). Evidence on breast-feeding patterns in low-income countries from nationally representative World Fertility Surveys and secondary sources shows that in all but a few such countries most children are breast-fed for at least a few months. The limited evidence available on trends seems to indicate a decline in the duration of breast-feeding, but in most of Asia and Africa breast-feeding is almost universal during at least the first 6 months. Earlier weaning is common in Latin America.
