While in some districts having drinking water is a given reality, there are others where there is a lack of access to this resource. Unfortunately, even today, 10.2% of the world population lives this situation and it could be worse in the coming years, according to UNICEF. Inhabitants in Pamplona Alta at southern Lima, Peru, daily suffer this harsh reality. This social challenge study attempts to define a methodology for an effective logistic planning of water distribution in Torres Minas. Currently, they obtain it from unsanitary and informal vendors. This chapter provides the basis of a new layout of the water distribution network based on clusters to efficiently satisfy water demand. Specifically, we propose the use of orderly delivery points called “bus-stops of water” in a two-echelon distribution system, whose optimization relies on a mixed-integer linear programming (MILP) technique. The objective of these guidelines is minimizing the transactional and transportation cost, while increasing the bargaining power of the community. Results showed a reduction of 52.67% and 26% in transactional and transportation costs, respectively, and a reduction of the associated risks of shortage and contamination of a tight delivery of water. Moreover, we foster the application of this methodology in other similar situations to produce sustainable growth for human settlements; regardless, there is a lack of access to water or a steep geography.

This paper aims to identify psychosocial, demographic and health risk factors associated with depression in older people.

A correlational study with 281 independent and autonomous persons of the community over 60 years old from Bogotá was conducted. The three instruments used to measure the variables included in the data analyses were Demographic and Health Data Questionnaire, Short version of 15 items of Geriatric Depression Scale (GDS) and Montreal Cognitive Assessment Test (MoCA).

Fifteen percent of the participants presented depression. Depression was associated with different demographic, low social support and health factors in this population group and was particularly high in women. Being a woman with poor social support networks and a previous history of depressive episodes should be considered as determining factors within a clinical risk profile for depression in older adulthood. It is essential to design prevention strategies focused on women and on the development of better social support in old age.

Depression is a prevalent and highly disabling disease, when it is suffered by an older person it is associated with higher mortality, functional dependence, poor physical health, worse quality of life indicators and psychological well-being. In the elderly, the clinical diagnosis of depression is difficult, as it has a high comorbidity and is often confused with other health conditions prevalent during older adulthood.
