Opening ParagraphAs one goes through the numerous publications concerning East Africa, it becomes apparent that certain subjects have rarely been approached, having been neglected or even totally ignored. Such is the case concerning the problems linked with the Hadrami diaspora, the extended study of which—apart from a few notable exceptions—has not yet aroused the interest of historians or the curiosity of anthropologists.

Monthly Survey

Drinking water sources derived from groundwater using selfsupply approaches are widely used in Bekasi City because only 26.8% of households are connected to the piped distribution. These self-supplied water systems can be assessed to determine how people choose a better drinking source. Therefore, this study aims to assess the service level attributes of self-supply, including accessibility, availability, and quality. A longitudinal monitoring method by means of a monthly survey to respondents was used to mens perceptions of taste, smell, color, availability, and safety. The results on both household and citywide scale showed boreholes were perceived to deliver a high service level. On the household scale, 93% of boreholes user got ‘high’ score for water service assessment, while dug wells were only 76%. During the 8 months survey, it was shown that 45% of respondents change their main source of drinking water from self-supply to other source for several reasons. Therefore, this study is expected to provide an overview related to the resilience of selfsupply drinking water for a certain period.

AbstractShifts in landscape heterogeneity and climate can influence animal movement in ways that profoundly alter disease transmission. Water sources that are foci of animal activity have great potential to promote disease transmission, but it is unknown how this varies across a range of hosts and climatic contexts. For fecal-oral parasites, water resources can aggregate many different hosts in small areas, concentrate infectious material, and function as disease hotspots. This may be exacerbated where water is scarce and for species requiring frequent water access. Working in an East African savanna, we show via experimental and observational methods that water sources increase the density of wild and domestic herbivore feces and thus, the concentration of fecal-oral parasites in the environment, by up to two orders of magnitude. We show that this effect is amplified in drier areas and drier periods, creating dynamic and heterogeneous disease landscapes across space and time. We also show that herbivore grazing behaviors that expose them to fecal-oral parasites often increase at water sources relative to background sites, increasing potential parasite transmission at these hotspots. Critically, this effect varies by herbivore species, with strongest effects for two animals of concern for conservation and development: elephants and cattle.
