Water Sowing and Harvesting (WS&H) consists of a series of ancestral procedures by which humans collect and infiltrate (sow) rainwater and runoff underground, so as to recover (harvest) it downgradient at some later time. This management of the water has made it possible for various regions of Ibero-America -that is, Latin America plus the Iberian Peninsula-to overcome dramatic cultural and climatic changes over the centuries. The principles governing WS&H coincide with those pursued under the present paradigm of Integrated Water Resource Management. Moreover, WS&H implies a better use of water and enhanced conservation of the environment and patrimony, as well as recognition of rural communities as vital custodians of the land and of its relevant cultural aspects. The main WS&H systems that serve Ibero-American countries are described here, emphasizing the principles underlying this means of water management as exemplary of hydro-geo-ethical systems.

Objective: To assess the self-reported vaccination in older adults within the city of Bogotá and its distribution by sociodemographic factors. Methods: Data analyzed was taken from the SABE-Bogotá study. A total of 2000 persons aged 60 years and older were selected for this cross-sectional population-based study. Bivariate and multivariate analyses were performed testing the association between vaccination and sociodemographic factors. Results: A total of 73.0% of respondents received the influenza vaccine, 57.8% received pneumococcal vaccine and 47.6% received tetanus vaccine. In multivariate analyses, individuals aged between 65-74 years had higher odds of receiving influenza, pneumococcus and tetanus vaccination, compared to those between 60-64 years. Older adults with higher socioeconomic status (SES) had lower odds of having influenza and pneumococcus vaccines, compared to those with lower SES (OR= 0.16 95% confidence intervals= CI 0.08-0.30; OR 0.20 95% CI 0.10-0.38, respectively). Individuals covered by health insurance (contributive or subsidized) had higher odds (between 3 and 5 times higher) of having influenza, pneumococcus and tetanus vaccination, compared to those with no insurance. Conclusion: Older adults between 65 and 74 years, those with health care coverage and people with low SES are groups that have increased odds for self-reported vaccination. Further studies should identify factors that increase vaccination coverage in these groups and implement interventions targeted at improving coverage among older adults in general.
