Abstract Background Fine-scale mapping of schistosomiasis to guide micro-targeting of interventions will gain importance in elimination settings, where the heterogeneity of transmission is often pronounced. Novel mobile applications offer new opportunities for disease mapping. We provide a practical introduction and documentation of the strengths and shortcomings of GPS-based household identification and participant recruitment using tablet-based applications for fine-scale schistosomiasis mapping at sub-district level in a remote area in Pemba, Tanzania. Methods A community-based household survey for urogenital schistosomiasis assessment was conducted from November 2020 until February 2021 in 20 small administrative areas in Pemba. For the survey, 1400 housing structures were prospectively and randomly selected from shapefile data. To identify pre-selected structures and collect survey-related data, field enumerators searched for the houses’ geolocation using the mobile applications Open Data Kit (ODK) and MAPS.ME. The number of inhabited and uninhabited structures, the median distance between the pre-selected and recorded locations, and the dropout rates due to non-participation or non-submission of urine samples of sufficient volume for schistosomiasis testing was assessed. Results Among the 1400 randomly selected housing structures, 1396 (99.7%) were identified by the enumerators. The median distance between the pre-selected and recorded structures was 5.4 m. A total of 1098 (78.7%) were residential houses. Among them, 99 (9.0%) were dropped due to continuous absence of residents and 40 (3.6%) households refused to participate. In 797 (83.1%) among the 959 participating households, all eligible household members or all but one provided a urine sample of sufficient volume. Conclusions The fine-scale mapping approach using a combination of ODK and an offline navigation application installed on tablet computers allows a very precise identification of housing structures. Dropouts due to non-residential housing structures, absence, non-participation and lack of urine need to be considered in survey designs. Our findings can guide the planning and implementation of future household-based mapping or longitudinal surveys and thus support micro-targeting and follow-up of interventions for schistosomiasis control and elimination in remote areas.

Housing is a fundamental human need, until now, making sure that every person has access to good quality housing is a grave challenge facing Bamenda Urban Space. This paper seeks to examine the housing situation and challenges to housing development in Bamenda Urban Space. The study adopted the mix method approach which involves triangulation of quantitative and qualitative methods of data collection. Primary data were obtained from field observations, interviews and questionnaires administered to households. Secondary data were obtained from relevant official documents, published and unpublished sources. Satellite imageries and ArcGIS were used to describe the pattern of growth in built-up areas between 1986 and 2019. Data from questionnaire was entered using Epi Data Version 3.1, analysed using the Statistical Package for Social Science Standard version 21.0 and presented in the form of tables, figures, plates and maps. Findings on housing situation revealed that, although the housing structures has improved, the housing designs, technology and level of maintenance are still low. The irregularity and unreliability in water supply, electricity supply and waste management systems have turned most households to alternative sources with poor quality. Urbanisation and urban growth are occurring without a concurrent increase in housing supply resulting to congestion, deterioration of basic services, pollution, inaccessibility, social vices, lack of privacy, poor ventilation and natural disasters amongst others. The paper, therefore, calls for the rehabilitation and renovation of dilapidated housing structures, provision of basic services, construction of low-cost housing, encourage financial institutions to grant loans to real estate developers at low interest rate.

This article’s main objective is to present some results of a study carried out in Castro de Terronha, located in the Union of Cardielos and Serreleis parishes, county and district of Viana do Castelo, North of Portugal. This settlement was discovered and excavated in 2000 by the archeology company Perennia Monumenta under the scientific direction of Francisco Queiroga. The text focuses on the analysis of structures and indigenous ceramic and lithic remains discovered in sector A. The seven circular structures under study correspond to probable housing structures. Three of them have a vestibule attached. These would be about 5–6 m in diameter—a device of reasonable quality. Also found was a section of wall that ends abruptly, adjoining a great outcrop. Most of the ceramic specimens in articulation with the architectures revealed numerous similarities in morphological, technical and decorative terms with that of the Late Iron Age and the beginnings of Romanization in the Cávado Basin River. The set of remains suggests this settlement was involved in subsistence activities, metallurgy and trade.
