The paper analyzes the impact of the El Niño and La Niña phenomena on both precipitation and agricultural production in the Department of Atlántico. Historically, droughts, anomalous rainy periods, and floods have constantly affected this region. Findings show that under El Niño conditions, rainfall is below average, while La Niña causes above-average rainfall. Sesame and banana yields increase when rainfall is above average (usually under La Niña conditions) during the short dry season and both the first and second rainy seasons. The above-average rainfall in the dry season has a positive impact on cassava yields. Corn yields increase if the recorded rainfall in the short dry season is above average and decrease under above-average precipitation in the second rainy season. Bean yields decrease when rainfall is above average during the first and second rainy seasons and increase when rainfall is above average in the short dry season. Cotton yields decrease in cases of above-average rainfall in the second rainy season, while sorghum does not present noticeable responses to precipitation anomalies. [ABSTRACT FROM AUTHOR]

The aim of this paper is to identify digital territorial segregation in the city of Bogotá, Colombia. The primary source of information is the Quality of Life Survey (ECV) made in Bogotá in 2007. Once the elements of the theoretical framework are exposed, the research results are addressed: 1) Internet connection and computer ownership in households in the localities of Bogotá, and 2) relational indicators for assessing territorial segregation in the city. Research demonstrates that digital territorial segregation in Bogotá is a fact that cannot be denied nor hidden. [ABSTRACT FROM AUTHOR]
