This study (https://doi.org/10.1007/s12517-017-3298-0) assesses the impacts of untreated wastewater discharge from Sulaimani City, Iraq, into the Tanjero River and proposes a framework for wastewater treatment planning. Nine sewer outlets representing residential, commercial, industrial, tourism, and hospital effluents were sampled over a year, and physicochemical analyses revealed elevated levels of turbidity, total dissolved solids, hardness, nitrates, and heavy metals—particularly in industrial zones. Questionnaire surveys conducted in 31 surrounding villages indicated significant health burdens, including chronic diseases, diarrhea, typhoid, skin disorders, and cancer, alongside impacts on livestock, fisheries, and agricultural productivity. Rice cultivation has nearly disappeared, and vegetable farming has declined due to water contamination. The findings highlight severe environmental and public health risks from current practices, where raw wastewater is still used for irrigation and animal watering. To mitigate these impacts, the study recommends constructing two wastewater treatment plants with stormwater retention structures, enforcing pretreatment of industrial effluents, and introducing appropriate on-site sanitation for unconnected households. Adoption of these measures would safeguard water resources, improve public health, and enable the safe reuse of treated wastewater for agriculture and industry.

This dataset represents the digitized version of the Geological Map of Somalia (scale 1:1,500,000), compiled between 1987 and 1991 and printed in 1994. The map was edited and coordinated by E. Abbate, M. Sagri, and F.P. Sassi, with contributions from the Faculty of Geology, Somali National University (Mogadishu) and the Universities of Florence and Padua, Italy, along with several Somali and international collaborators. The map provides a comprehensive overview of Somalia’s geological formations, stratigraphy, and structural features, covering the Gulf of Aden margin, central basins, and the Indian Ocean coastal belt. Lithological units range from Precambrian crystalline complexes to recent Quaternary deposits, with detailed symbology distinguishing volcanic, sedimentary, and metamorphic sequences. The original map also incorporates tectonic structures, fault systems, and stratigraphic cross-sections that are not included in the SHP file, but the original map is provided georeferenced in EPSG:32638 - WGS 84 / UTM zone 38N.

The digitization process involved georeferencing, vectorization, and attribute assignment of geological units and structures to enable spatial analysis within modern GIS environments. This dataset supports research and decision-making in natural resource management, groundwater assessment, mineral exploration, land-use planning, and academic studies. During the digitization process, the original projection of the map was not specified, requiring approximate control points for georeferencing. As a result, minor distortions may remain, and the spatial alignment is not perfectly accurate.
